Kev tiv thaiv xob laim zoo

Kev tiv thaiv hluav taws xob zoo yuav tsum tau ua rau txhua qhov AC fais fab inlets ntawm kev saib xyuas kev ruaj ntseg. Thiab yuav tsum xyuas kom meej tias lub tsev nyob qhov twg cov cuab yeej nyob rau hauv muaj ib tug zoo hluav taws xob tiv thaiv grounding system, thiab ntxiv kom paub tseeb tias seb lub xob tiv thaiv ntaus ntawv ntawm lub tsev nyob qhov twg yog siv kom raug.

Kev sib txuas hluav taws xob tiv thaiv hluav taws xob yuav tsum tau teeb tsa ntawm AC lub zog nkag ntawm cov khoom siv hauv ntej. Xav txog tias cov khoom siv hluav taws xob ntawm kev saib xyuas kev ruaj ntseg feem ntau tsis yog ib puag ncig kev siv hluav taws xob zoo heev, feem ntau muaj ob peb volts, kaum volts, los yog kaum tawm volts lossis ntau dua ntawm xoom thiab hauv av; Ntxiv rau, thaum txhim kho ib-theem fais fab kev tiv thaiv Nws yog ib qho nyuaj rau kev paub qhov txawv ntawm xoom thiab nyob ntawm tej thaum siv cov mines. Raws li qhov xwm txheej no, nws raug nquahu kom tsis txhob siv 1 ntxiv rau NPE tiv thaiv hom khoom thaum xaiv ib-theem fais fab surge protectors. Yog tias 1 ntxiv rau NPE tiv thaiv hom khoom raug xaiv, thaum muaj AC voltage ntawm NPE module, thaum NPE module ntsib ib qho overvoltage, nws yuav tsim lub hwj chim zaus freewheeling, ua rau nws nyuaj rau NPE module tua lub arc los ntawm nws tus kheej, ua rau NPE module hlawv tawm, lossis txawm tias nws yooj yim los nqa kev nyab xeeb xws li hluav taws.
