Neutral Grounding Resistorsxav tau kev saib xyuas tsis tu ncua. Raws li ib feem tseem ceeb ntawm lub zog tiv thaiv kev tiv thaiv hauv av, lawv muaj kev cuam tshuam rau ib puag ncig thiab kev laus thaum lub sijhawm ua haujlwm ntev -. Kev tu xyuas tiv thaiv kev ua haujlwm tsis ua haujlwm uas tuaj yeem ua rau muaj kev nyab xeeb.
Lub voj voog txij nkawm nyob ntawm qhov kev siv qhov xwm txheej: Rau kev siv hluav taws xob dav dav, nws raug nquahu kom kuaj xyuas txhua 6 lub hlis; rau siab- zaus ua haujlwm zaus xws li lub zog tshiab fais fab nroj tsuag thiab siab-voltage substations, qhov no yuav tsum luv luv rau ib zaug txhua 3 lub hlis. Yog tias muab tso rau hauv qhov chaw ntub lossis plua plav, yuav tsum tau kuaj xyuas tshwj xeeb ntxiv 1-2 ib xyoos.
Cov khoom kho tshwj xeeb muaj xws li ob ntu: Ua ntej, kev tshuaj xyuas qhov muag, kuaj xyuas corrosion lossis deformation ntawm cov resistor casing, thiab xoob lossis oxidized terminals. Txhua yam teeb meem pom yuav tsum tau hais kom sai. Thib ob, kev ntsuas kev tiv thaiv, siv cov cuab yeej tshwj xeeb los ntsuas tus nqi tsis kam. Yog tias qhov sib txawv ntawm tus nqi pib tshaj ± 10%, kev laus hauv tsev lossis cov teeb meem noo noo yuav tsum tau tshawb xyuas, thiab hloov pauv yuav tsum txiav txim siab yog tias tsim nyog.
Nco ntsoov tias cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob sib txuas yuav tsum raug txiav ua ntej tswj xyuas qhov nruab nrab Grounding Resistor kom tsis txhob muaj hluav taws xob poob. Tsis tas li ntawd, lub tshav kub dissipation Cheebtsam ntawm lub resistor yuav tsum tsis txhob muab pov tseg. Cov plua plav ntau dhau ntawm lub dab dej kub tuaj yeem ua rau tsis muaj cua sov dissipation, overheating, thiab ua kom lub cev muaj zog. Lub dab dej kub yuav tsum tau muab ntxuav tom qab txhua qhov tu.
