The current zero phenomena is an indicator for the pressure, temperature, ion density, plasma flow, etc.
零区现象 是压力,温度,离子密度,等离子流等的指标.
Current zero measurements are used to understand the phenomena of the arc and to identify the dominant parameters for a successful interruption of the current.
零区测试 用来了解电弧现象以及确定成功的电流中断的主要参数.
Current zero (CZ) refers to the interruption phenomena in high power circuit-breakers.
零区 (CZ) 指的是在高功率断路器上的中断现象.
Since the DC current from an AC current zero crossing features, when the case of short-circuit current breaking, had difficulty extinguishing the arc, and therefore should be two-pole or three-pole series wiring methods to increase fracture, fracture bear part of the respective arc energy.
由于直流电流无交流电流过零点的特性,当遇短路电流开断时,电弧的熄灭都有困难,因此应采用二极或三极串联的接线办法,增加断口,使各断口承担部分电弧能量。
Since there is almost no free gas in the vacuum, therefore, when such contacts of the circuit breaker in the disconnected only emitted because of the high electric field, and the thermoelectric emission produces little vacuum arc so that it can in the first current zero crossing off, so that both ensures that the interrupter can be within a very short time, but not so in the system to produce a high pressure changes due to the Shaanxi speed current.
由于真空中几乎不存在气体游离的问题,因此这种断路器的触头在断开时只会因为高电场发射和热电发射产生很少的真空电弧,使它能在电流第一次过零时熄灭,这样既保证了能够在很短的时间内灭弧,又不至于在系统当中由于陕速的电流变化而产生高压。
The last time Vietnam reduced its export tax was in November, cutting a three per cent tax on centrifugal rubber and synthetic rubber to the current zero level.
越南最近一次减少出口税是在11月份,对离心橡胶减少了3%的税收,合成橡胶 到目前的零水平。
The flow and the heat conducting ability of the SF6-gas drain the energy from the electric arc, and thereby cause it to extinguish at the current zero transition.
SF6气体的流动及热传导能力将能量从电弧中排出,从而导致电弧在零电流转换处熄灭。
Are we the same Henaih current zero equation?
难道我们同样Henaih电流过零式 ? )
Even Japan, the country most marred by deflation, is contemplating monetary policy options beyond its current zero interest rate policy as its economic recovery gathers strength.
即使在最受通货紧缩之累的日本,随着经济的复苏,也在考虑在现行的零利率政策之外选择其它货币政策。
The case for carbon taxes has long been compelling. With the recent steep fall in oil prices and associated declines in other energy prices it is overwhelming. There is room for debate about the size of the tax and about how the proceeds should be deployed. But there should be no doubt that starting from the current zero tax rate on carbon, increased taxation would be desirable.
碳税问题长期以来一直备受关注。随着近期油价暴跌以及其他能源价格的相应下挫,征收碳税已是势在必行。我们有讨论碳税的规模以及税收如何运用的空间。但毫无疑问的是,以当前碳排放零税率为起点而增加的税收将是可行的。
