电力零线地线在供电线路中的作用

长期以来,不管是家庭用电还是工业用电,都是指交流电。它可以很方便的把电能转化为各种功能,极大地便利了我们的生活。因此安全正确的使用交流电就显得尤为重要。而交流电中通常有三根线与我们用电息息相关,这三根一般称为电力零线、地线与电力火线,它们在供电线路中一样重要。在电路中干线零线断路、入户零线错接、户内零线断路及地线开路对安全用电造成严重的危害。

For a long time,whether it is domestic electrical or industrial use of electricity,is refers to the alternating current.It can be very convenient to the electrical energy into thevarious functions,bring great convenience to our life.Therefore the use of alternating current security right is particularly important.While the AC usual y have three lines and we use electricity is closely linked,the three root general y known as the powerzero line,ground wire and power wire,they in the power supply line is as important.Circuit breaker,home lines in the circuit zero line zero line wrong then,indoor zero line circuit and ground open on the safe use of electricity causes serious harm.
