Kev tiv thaiv xob laim ntawm lub substation Rau txoj kab hluav taws xob tiv thaiv, tsuas yog yuav tsum muaj kev tiv thaiv xob laim ib nrab, uas yog, raws li qhov tseem ceeb ntawm txoj kab, tsuas yog yuav tsum muaj qee theem ntawm kev tiv thaiv xob laim. Thiab rau cov nroj tsuag fais fab, substation yuav tsum tau ua tiav xob laim. Kev sib tsoo xob laim hauv cov chaw tsim hluav taws xob thiab cov chaw nres tsheb yog los ntawm ob yam: xob laim tawm ncaj qha ntawm cov chaw tsim hluav taws xob thiab cov chaw nres tsheb; xob laim tawm tsam ntawm cov kab sib txuas ua kom muaj hluav taws xob tsis muaj zog uas cuam tshuam cov chaw tsim hluav taws xob thiab cov chaw nres tsheb hauv txoj kev. Txhawm rau tiv thaiv lub substation los ntawm cov hluav taws xob ncaj qha, koj yuav tsum tau nruab cov hlua hluav taws xob, cov hlua hluav taws xob, thiab cov nets hauv av zoo. Kev teeb tsa cov hlua hluav taws xob (xaim) yuav tsum ua kom tag nrho cov khoom siv thiab cov tsev nyob hauv lub chaw nres tsheb hauv qhov chaw tiv thaiv; Tseem yuav tsum muaj qhov chaw txaus ntawm cov khoom tiv thaiv thiab cov hlua hluav taws xob (xaim) hauv huab cua thiab cov khoom siv hauv av kom tiv thaiv kev tawm tsam (rov qab flashover). Kev teeb tsa hluav taws xob hluav taws xob tuaj yeem muab faib ua hluav taws xob hluav taws xob ywj pheej thiab cov hlua hluav taws xob thaiv. Lub hwj chim zaus grounding kuj ntawm ntsug xob laim pas nrig yuav tsum tsis txhob ntau tshaj 10 ohms. Lub rwb thaiv tsev ntawm lub zog xa hluav taws xob mus txog thiab suav nrog 35kV tsis muaj zog. Yog li ntawd, nws tsis tsim nyog rau nruab ib lub teeb ci ntsa iab, tab sis tus pas nrig hluav taws xob. Qhov hluav taws xob nyob deb ntawm qhov chaw sib txuas hauv av ntawm tus pas nrig thiab lub ntsiab hauv av thiab cov ntsiab lus hauv av ntawm lub ntsiab transformer yuav tsum siab tshaj 15m. Txhawm rau kom muaj kev nyab xeeb ntawm lub ntsiab transformer, lub teeb ntes hluav taws xob tsis raug tso cai rau nruab rau ntawm lub qhov rooj qhov rooj transformer.
