　　當負載電流過零時，雙向可控硅(晶閘管)開始換向，但由于相移的關系，電壓將不會是零。所以要求可控硅(晶閘管)要迅速關斷這個電壓。如果這時換向電壓的變化超過允許值時，就沒有足夠的時間使結間的電荷釋放掉，而被迫使雙向可控硅(晶閘管)回到導通狀態(tài)�！　∈紫�，斷路器在電路中主要是用于過電流保護，在電路有過載或短路情況發(fā)生時，產生電流過大，超過其承受電流適范圍時，斷路器切斷電路，防止故障進一步擴大，這里一個關鍵的地方就是過電流。第二，空開選擇一般是依據總電流的1.2~1.3倍,如果是電動機，就要考慮啟動電流,一般是遠遠高于1.3倍，這有矛盾之處，所以，綜上分析，配線斷路器不宜用于保護電動機線路中。

　　:降壓啟動是指利用啟動設備或線路，降低加在電動機定子繞組上的電壓來啟動電動機。降壓啟動可達到降低啟動電流的目的，但由于啟動力矩與每相定子繞組所加電壓的平方成正比，所以降壓啟動的方法只適用于空載或輕載啟動。　　(5)油保護方式，N-不帶金屬器；帶金屬器不表示。(6)系列序 ，用數字表示。(7)額定電壓，單位為kV。(8)特殊環(huán)境，用下列字母表示：GY-高原地區(qū)用；W-污穢地區(qū)用；TA-干熱帶地區(qū)用；TH-潮熱帶地區(qū)用。例如，JDX-110型表示單相、油浸式、帶零序電壓繞組的110kV電壓互感器。

　　2）“電表測量電壓值”。用萬用表的交流電壓250V（或500V）檔測量電動機輸入端的電源電壓是否達到規(guī)定的電壓值，例如220V（一般允許相差±5%）。如較低，應進一步測量上一級電源端（例如插座的輸入端、電能表的輸出和輸入端等）的電壓，如發(fā)現上一級或上幾級的電壓正常，則應檢驗中間的環(huán)節(jié)是否有不良等故障，如有則設法排除后再進一步檢查。

 　　如果對應了程序1這樣的程序。它是這樣工作的：輸入、輸入鎖存，按照程序1從左到右從上至下掃描運算出結果，輸出鎖存、輸出。它是在時鐘信 的驅動下，定時串行工作的。即輸入，程序運算，輸出，周而復始反復進行。只是由于串行程序掃描運行的速度太快而我們察覺不到而已。
