1. Kev xaiv lub ntsiab tsis tseem ceeb: valve ntes yuav tsum raug xaiv raws li cov qauv kev qhia hauv cov kev xav tau.
2. Thaum siv lub valve arrester rau xob laim overvoltage tiv thaiv, ntxiv rau rotating motors, xaiv ntes nrog txawv kev khiav hauj lwm voltage ranges thiab txawv system software grounding txoj kev.
3. Qhov seem ua hauj lwm siab ntawm lub valve ntes nyob rau hauv tus qauv nqi thiab tawm tam sim no tsis tuaj yeem tshaj 71% ntawm cov hluav taws xob impulse tag nrho-yoj tiv thaiv kev ua haujlwm voltage (BIL) ntawm cov khoom siv hluav taws xob hauv kev saib xyuas (tshwj tsis yog cov tshuab hluav taws xob tig).
4. Qhov ntsuas tam sim no ntawm cov hlau oxide ntes thiab cov pa roj carbon sib xyaw valve ntes yuav tsum tau ua raws li cov cai hauv qab no:
(1) 110kV tsim nyog grounding tiv thaiv tsis pub tsawg tshaj 0.8Um.
(2) 3 ~ 10kV thiab 35kV, 66kV system software tsis tsawg dua 1.1Um thiab UM;3kV thiab saum toj no generator teeb qhov system software siab tshaj plaws kev khiav hauj lwm voltage tsis tsawg tshaj li 1.1 npaug.
(3) Qhov ntsuas tam sim no ntawm qhov nruab nrab ntawm qhov ntsuas tsis pub tsawg tshaj 0.** Um thiab 0.58Um feem;Qhov siab tshaj plaws kev khiav hauj lwm voltage ntawm 3 ~ 20kV generator teeb tsis tsawg tshaj li 0.** zaug.
5. Thaum xaiv cov hlau oxide ntes tsis muaj qhov tsis muaj qhov tsis zoo li cov khoom siv tiv thaiv xob laim overvoltage, yuav tsum ua raws li cov kev cai sib xws.
6. Rau 110kV thiab 220kV transformers uas nruab nrab taw tes yog cais raws li cov txheej txheem insulating, yog tias qhov kev sib cais hloov nrog cov tsis zoo synchronous kev ua tau zoo, cov hlau oxide ntes yuav tsum tswj qhov nruab nrab ntawm lub transformer.
7. Cov hlau tsis muaj hlau oxide ntes tau raug cais raws li lawv tus qauv them nqi thiab tso tawm tam sim no.
8. Tus ntes nrog lub kaw lus software ntsuas tam sim no ntawm 35kV thiab siab dua yuav tsum tau nruab nrog kev them nyiaj thiab tawm ntawm lub cev saib xyuas software.
