The seismic sea wave disaster that broke out one year ago lets China of Japan discuss the nuclear cha nged. Before it is unable to confirm the nuclear power totally safe, Japanese Government determines to give up this power generating way. And the data reveal, this will make Japan fall into the awkward situation of the electricity in short this summer.

The nuclear power falls into in an all-round way and stagnates at the end of April

20,Kansai Electric Power Co. lie in the nuclear power unit pays and checks and stops generating electricity regularly high the 3rd in Ding such as bank such as county such as Fukui, so far 11 nuclear powers and all breakdown of unit of this company. The whole the intersection of Japan and 54 nuclear aircrew have two left generate electricity still o nly, two the intersection of nuclear power and aircrew these enter and check regularly too by the end of A pril, the Japanese nuclear power units all stop rotating when the time comes.

Been requiring the government to issue the new safety standard all the time because of the unit locat ion of nuclear power, but Japanese Government should pay the formulation of the consumption tax and have no time to take to busy into account, so, it is not within the foreseeable future that the topic that the nuclear power restarts is terrific. Occupy 30% nuclear power of rivers and mountains, supply of electric power of Japan, fall into, leave unused once, this impact on Japanese society will be hard to assess this summer.

The substitute of electricity generation by thermal power will tie down economy

Lose nuclear power support, the intersection of Japan and in the future broad the intersection of reliance and electricity genera tion by thermal power China. But even if circulate the electricity each other if necessary between Utilities Electric Co., every company will generally feel because of lacking the nuclear power that it is tense to supply. The analyst points out, the regional government should start stricter ” Restrict the cable order ” ,Strengthen the festivals of family and enterprise electricity degree, but the enterprises including companies such as Fujitsu, Hitachi and Panasonic,etc. say one after another, the means is nearly used up to economize on electricity, has already had no leeway in economizing on electricity again.

Common people enough, but Utilities Electric Co. shoulder huge to lose. It is estimated, if the electricity generation by thermal power all replace the nuclear power, Utilities Electric Co. should increase the fuel cost of 3,000 billion Japanese yen every year.

In 2011, 9 final accounts results of April-December of Utilities Electric Co. in Japan revealed, except there is no Okinawa Utilities Electric Co. of the nuclear power unit, 8 Utilities Electric Co. all suffer the loss. Among them, it is the most serious that electricity of Tokyo, Northeastern electricity, Kansai Electric Power suffer the loss, it is 623 billion Japanese yen, 167,700 million Japanese yen and 118,100 million Japanese yen respectively.

All nuclear power units stopped generating electricity in 2012, replace by generation of electric power by thermal power, it is more serious to suffer the loss. As time passes, managing Utilities Electric Co. hard to carry on certainly will shift the cost, it is certain to aggravate enterprise’s burden after raising the price of electricity, increase the house expenses, bring the negative effect to Japan’s economy.

Watch the face of the Middle East in Japan’s energy supply

The question of making Japanese Government worry about most is not the loss of Utilities Electric Co., and lie in whether could ensure the supply of electric power.

As the fuel of generation of electric power by thermal power, the import of the liquefied natural gas has become a great difficult matter too at present. The data revealed, 28.1% of the Japanese liquefied natural gas stemmed from Middle East country in 2011, but in view of the tense relation between America and Europe and Iran at present, Hall wood noncongestion of straits influence Japan nearly 1/3 natural gas, import directly or not now. So, once fall into the war in the Middle East area, Japanese even basic generation of electric power by thermal power will be hard to carry on.

In order to avoid the awkward condition that probably falls into, Japanese Government has already begun to consult with U.S.A. and import the liquefied natural gas from this country, in fact, restrict export the intersection of natural gas and U.S.A. in strategic materials to these resource straight, it is still a question mark whether could meet Japan’s demand finally.

On February 15, American energy minister ZhuDi wen visited southern Utilities Electric Co. Vogt in Georgia state to tie tight Vogtle Nuclear power station. Since February 9, after the American nuclear energy supervises the committee and sanctions building two of new nuclear reactor in this nuclear power station, here becomes the focus that industry pays close attention to. ZhuDi wen regards as the illustration that U.S.A. supports the development of nuclear power here even more.

After 34 years, U.S.A. sanctioned the licences of the newly-built nuclear power plant for the first time, initiates the whole America even international community to the development of nuclear energy and dispute of rejuvenation. But, can these two of nuclear reactor be criticized and can become the signal of American nuclear power rejuvenation? May not!

Vogt will adopt the electric Model AP1000 reactor of west room of U.S.A. to be designed if Vogt ties the nuclear power unit No. 3 and 4 tight. American natural resources the intersection of committee and energy, environment and Yang, senior consultant of climatic change, prosperous and strong to think, can’t it supervises committees to be whether new response pile up conduct matter, regard the intersection of American and signal that nuclear energy rejuvenated as the intersection of American and nuclear energy, perhaps this measure but there aren’t piling AP1000 at U.S.A. type,it so as to last U.S.A. in should piling leading to research and develop respect, let alone become the reason why the other countries advance the nuclear power.

ZhuDi wen shows too, in order to keep the leading position in nuclear power industry of the whole world when Vogt ties the nuclear power station tight to give a lecture, U.S.A. needs to let scientist and engineer of the nuclear power understand the nuclear power of future generation even more.

As the fourth largest uranium resource producing country in the world, Namibia puts forward the idea of developing the national nuclear power undertaking as far back as 2008, and plan to build up a first nuclear power station by 2018. Chose the energy company with capability to become primary task of this country, but French enamel Company of sea of A entered the visual field of Namibia at this moment.

The materials reveal, the Namibian mineral resources are abundant, have ” The metal of strategy stores the storehouse ” Claiming is it main whether mineral deposit diamonding, uranium, copper, silver,etc.. Among them, it is renowned in the world that uranium is produced. The mining industry is its economic main pillar, 90% of the mineral products are used for exporting, the output value that the mining industry achieves accounts for its GDP nearly 20%.

Nanometer of lying in the intersection of cloth and desert only uranium mine in Namibia close to west peppery mountain Luo of coast, the uranium ore here is inlaid in the hard granite, has taken shape in several million years ago. Though hard mountain Luo right away find the radioactive mineral deposit as far back as 1910, confirm in 1928 that there is uranium. But because is unable to bear in economy, Namibia gave up after exploring some tentatively 1956, until 1976, Luo XinShan did not begin to exploit formally.

The data reveal, Luo XinShan’s uranium ore reserves probably account for 7.55% of the total reserves of global uranium ore. After the uranium ore of Namibia is exploited out, are mostly transported to places such as Central Europe, North America and Southeast Asia,etc., for local nuclear power station. According to the estimation by expert of mining industry of uranium, because China, Russia and India all plan to expand the nuclear energy plan 2030 years ago, the global uranium ore demand will increase twice, and the amount of time 6 that this demand has already made global uranium ore price rise violently in the following 25 years. Accompanied by the constant rising of uranium ore price, the prospect of mining industry of uranium of Namibia will be very clear.

At present, make every effort to open up group and Australian uranium ore company para cube energy Paladin Energy All main manufacturers of resources of uranium of this country. Among them, make every effort to open up attractiveness quite loud hard the intersection of mountain and assets Luo in the hand, last May, this company had said, plan, can be brought hard mountain Luo up to 5500 tons by annual output of uranium ore in 2012 year.

As to this plan, Namibia demonstrates the attitude absolutely supported, and suggest hoping commonly ” Share ” Achievement. A few days ago, the main developer’s French enamel group of sea of A of this country Trekkopje uranium mining area acted to some extent too, this is exactly what Namibia wanted. In fact, under the circumstances that this Pohamba, president of country, backs in a more cost-effective manner, the nuclear energy industry of Namibia is advancing steadily.

On February 9, after enamel agrees to carry on feasibility research to the Namibian nuclear power in the sea of A, Trekkopje project got the 5 – year long export and processed the licence. As far back as 2010, after Canada, the Niger and Kazakhstan will exploit the uranium ore respectively, the enamel of sea of A cast sight on Namibia at last. At that time, the enamel of sea of A declared, would go into operation in the middle ten days of 2012, annual production capacity was expected to reach 3000 tons, confident of making it become the largest open-air uranium ore in Africa.

Report, the Namibian government has already discussed with the enamel of sea of A according to Namibia’s ” receives the newspapers of people “, regard implementing the preferential policy of the tax revenue to Trekkopje project as the condition, exchanging France helps Namibia to carry on the feasibility research of nuclear power.

Namibian enamel, sea of A, process the intersection of company and the intersection of resource portion and the intersection of manager and sylies of the intersection of law and

Has if the squelch muting machine case does not think about

Squelch muting is becoming multi-user’s focus more and more, perhaps we have no way of choosing in the face of the brand machine, but still very big on DIY space that we can give play to. So there are the users of very high requirement to squelch muting, will often choose to meet one’s own demand by assembling even transforming the products by oneself.

But really make sure squelch muting is not too easy thing, because a thing is violated with squelch muting, that is to dispel the heat! Squelch muting and heat-dissipating itself are that a need excellent equilibrating the method and can reach the perfect intensity that give consideration to, it is designed that such as PWM fan etc. to appear in order to equilibrate these things.

But really make sure squelch muting is an easy thing? For example there are many heat-dissipating dead angles not very apt to solve in power, hard disk and some other places, solve these problems in suitable energy of player’s cost that this costs. We regard power of this one machine case as protagonist this time, come, say something about power and machine the intersection of case and squelch muting how many relations does it have really.

There is no fan power It is in fact very difficult

Get back to theme of us, heat abstraction of power speak easy in fact, say difficult and easy even. It is very simple to say easy connections, every player opening the power and seeing is sure to have very deep impressions on heat-dissipating system of the power, very thin the intersection of aluminium and slice even aluminium excellent and excellent the intersection of world and X loud power factory like most often, certainly for example such some ship is famous likes very much in the factory ,To the intersection of computer and friend that heat-dissipating system understand to some extent being will clear to adopt so simple and crude heat-dissipating system, reason have only one actually, that but power itself possess a too much one to be high to generate heat some.

The intersection of all parts of the world and about reducing energy consumption of electronic system various proposal, impel single-phase to exchange, input the intersection of power and designer into, adopt advanced the intersection of power and technology. In order to obtain the high power grade, these propose to require efficiency to be up to 87% and the above. Because the standard surges the formula flyback instead Traditional power such as the defying type are being too topological to support the grade of high efficiency with one pair of switches, so is and allow the resonance to be topological and replace the soft switch resonance gradually.

Operation principle

1 Fig. show for adopt three topological difference resonance of allowing person who defy topological, the intersection of LLC and resonance use soft the intersection of switch and the intersection of asymmetry and half topological bridge of technology instead Voltage sum of operation electric current wave form.

Fig. 1: Allow resonance, LLC and half a bridge of topological comparison of asymmetry

Export the electric current of the diode to drop to zero

Slope change when one grade of ends was coupled back to the secondary end originally

The body diode is led openly, until MOSFET it is open to lead

These three kinds are topological to reduce the openning of MOSFET to loss by different technology, lead the calculation formula of the open loss as follows:

Usually the switch type steps down the switch transistor of the changer is connected in the circuit, and the switch type steps up the switch transistor of the changer and supports the parallel one, it is inductance coil and diode with the components and parts which support series connection connection. So if use these two kinds of changers as backing up, when the power is in the state of awaiting the opportune moment, step down changer fail because of the intersection of switch and transistor the intersection of people and thorough fare of output end cut off, consumption of awaiting the opportune moment is very little, consume the electric current under 1uA. But step up the changer is quite different. Because switch in charge of though end cut off, fail direct-flow thorough fare of people between the output end, battery can from inductance coil and diode and condenser of output end, voltage be lasted return circuits direct-flow to be lasted resistance, the electric current flowing through is about several dozen microamperes, in addition will flow through electric current in load too, the size of the electric current varies with circuit.

Loss in order to reduce this kind of electric current, can adopt two kinds of following methods.

1.Set up the switch between inputting the output ends

Set up the switch on the circuit while inputting the output ends, separate Vin and Vout while awaiting the opportune moment. The switch can adopt a kind of mechanical switch of relay, can adopt the electronic switch that MOSFET form too.

The producer produces and takes load to cut off the stepping up changer IC of the function recently, adopt the circuit that Fig. 1 shows while using. End with the aid of the intersection of P and the intersection of ditch and dishes of MOSFET Tr2 while awaiting the opportune moment, cut off input terminus and direct-flow thorough fare of output end.

Fig. 1 sets up the switch between inputting the output ends
