　　首先，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(chǎn)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(guān)鍵的地方就是過電流。第二，空開選擇一般是依據(jù)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。

　　如果主觸點燒毀，觸點雖然也可以更換，但因為曾經(jīng)更換過一批效果不太好，一方面，好的觸點成本不低，如果哪個壞更換那個，造成新舊觸點搭配，使用壽命仍然不會太久，另一方面，更換過主觸點的器耐用性比較差，因為有些器是緊密卡件互卡，拆開再裝容易損毀卡點，所以也不建議更換。

批發(fā)韓國AND KOREA AD-4212C-301應用推薦　　1、萬用表測電流，三相不平衡率不大于10%；2、搖表測絕緣，每相對地、相間均不小于0.5兆；3、電橋測直流電阻，三相不平衡率不大于2%；即首先用萬用表去量電壓以及電阻（沒搖表的情況下），首先在電機電源側(cè)UVW三相中選取兩相，測量一下兩端電壓是否為380v（高于380V沒事）中有時電壓不導致的?！　‰姍C額定功率即電動機的軸輸出功率，也是負載計算時所采用的數(shù)據(jù)。P1在負載計算中作用不大，一般不再進行換算。例如一臺小型電機的銘牌數(shù)據(jù)：額定功率250W，額定電壓380V，額定電流0.85A，功率因數(shù)0.68。如果不算效率時，額定電流=250/(1.732*380*0.68)=0.56A，跟0.85A不符；如果算效率，額定電流=0.85=250/（1.732*380*0.68*效率）；由上式計算效率為：電動機效率=250/(1.732*380*0.68*0.85)=0.66。
　　4、輸出特性（1）SSR給出的額定輸出電流一般指常溫下或常溫到高溫下的額定輸出電流而且對大于10A的繼電器還指帶有規(guī)定散熱器時的額定輸出電流。對功率SSR，當工作溫度上升或不帶散熱器時，輸出電流相應下降。

 　　8、電動機掃膛產(chǎn)生掃膛的原因是：電機軸上支承圈磨損嚴重、轉(zhuǎn)子鐵心位移，或因其他原因使定子鐵心位移，造成電機錐形轉(zhuǎn)子與定子間隙太小發(fā)生掃膛。電機嚴禁“掃膛”，當發(fā)生掃膛后，應拆下支承圈進行更換，定子轉(zhuǎn)子錐面之間的間隙使之均勻，或送到維修廠進行修理。
