其實(shí)像上面說的斷路器功率一般都很大（對(duì)于家庭用電所用功率來說），為了一般在線路的后面還會(huì)再加幾個(gè)1P的斷路器，這種斷路器一般功率都比較小，上找了一張圖片，對(duì)于1P的斷路器，直接接一個(gè)從2P斷路器出來的火線。
缺點(diǎn)：啟動(dòng)轉(zhuǎn)矩較小，功率因數(shù)較低，轉(zhuǎn)速不易調(diào)節(jié)，直接啟動(dòng)時(shí)啟動(dòng)電流大。正常情況下，鼠籠型電機(jī)冷狀態(tài)下運(yùn)行啟動(dòng)2-3次，每次間隔時(shí)間不得小于5分鐘。熱狀態(tài)下運(yùn)行啟動(dòng)一次。鼠籠式異步電動(dòng)機(jī)在啟動(dòng)時(shí)，還容易造成鼠籠斷條?！ 、谝?yàn)檩o助繞組的一端與b相接地點(diǎn)相連，由于基本二次側(cè)繞組上有負(fù)荷電流流過，在電纜芯出上產(chǎn)生電壓降，使正常開口三角形有電壓3U0，對(duì)零序方向元件不利。若單獨(dú)從接地點(diǎn)引接零序方向繼電器回路，則接線較為復(fù)雜。在中性點(diǎn)接地系統(tǒng)中，由于中性點(diǎn)無任何斷開觸點(diǎn)，可靠性高。

供水接線供水接線需要用到液位繼電器的2和3這組常開點(diǎn)，當(dāng)水位下降到低時(shí)，2和3就會(huì)導(dǎo)通水泵開始抽水。當(dāng)水位達(dá)到高時(shí)，2和3復(fù)位斷開電機(jī)停止，所以可以把2和3理解為一組開關(guān)。排水電路排水電路需要用到液位繼電器的3和4這組常閉點(diǎn)，當(dāng)水位排到低時(shí)，3和4這組常閉點(diǎn)就會(huì)斷開，水泵就會(huì)停止排水。
高壓斷路器的合閘時(shí)間是指斷路器從接到合閘指令（即合閘線圈加上電壓）起到斷路器三相主觸頭均為止所需要的時(shí)間。電力系統(tǒng)對(duì)合閘時(shí)間要求不太嚴(yán)格，一般合閘時(shí)間都大于分閘時(shí)間，但希望。高壓斷路器的分、合閘不同期時(shí)間是指斷路器各相間或同相各斷口間分、合閘的時(shí)間差?！ 』ユi原理器KM1和KM2的主觸頭決不允許同時(shí)閉合，否則造成兩相電源短路事故。為了保證一個(gè)器得電動(dòng)作時(shí)，另一個(gè)器不能得電動(dòng)作，以避免電源的相間短路，就在正轉(zhuǎn)控制電路中串接了反轉(zhuǎn)器KM2的常閉輔助觸頭，而在反轉(zhuǎn)控制電路中串接了正轉(zhuǎn)器KM1的常閉輔助觸頭。
