1.正常倩況下接通和斷開(kāi)高壓電路中的空載及負(fù)荷電流; </p> <p> 2.在系統(tǒng)發(fā)生故障時(shí)能與保護(hù)裝置和自動(dòng)裝置相配合迅速切斷故障電流防止事故擴(kuò)大從而保證系統(tǒng)安全運(yùn)行。 </p> <p> 一般情況下塑殼斷路器本身不存在潤(rùn)滑方面的問(wèn)題，需要潤(rùn)滑的常常是它的操動(dòng)機(jī)構(gòu)。熱繼電器的作用是電動(dòng)機(jī)過(guò)負(fù)荷時(shí)自動(dòng)切斷電源，熱繼電器的構(gòu)造是兩片膨脹系數(shù)不同的金屬片構(gòu)成，電流過(guò)大時(shí)膨脹系數(shù)大的先膨脹，起到切斷電源的作用。熱繼電器動(dòng)作后有人工復(fù)位和自動(dòng)復(fù)位。熔斷器作用：當(dāng)電路發(fā)生故障或異常時(shí)，伴隨著電流不斷升高，并且升高的電流有可能損壞電路中的某些重要器件或貴重器件，也有可能燒毀電路甚至造成火災(zāi)。

2)報(bào)警觸頭主要用于斷路器的負(fù)載出現(xiàn)過(guò)載、短路或欠電壓等故障時(shí)而自由脫扣。報(bào)警觸頭的工作電流是：AC380V、0.3A、DC220V、0.15A，一般不會(huì)超過(guò)1A，而發(fā)熱電流可以是1～2.5A范圍。 </p> <p> <br /> </p> <p> <br />
