Apha, i-SPL, umzi-mveliso waseTshayina wenguqu, ikunika ireferensi malunga nokhuseleko lokuntywiliselwa kwezothutho. Kukho izixhobo ezi-3 zokhuseleko eziphambili:

I-1, i-gas relay: isetyenziselwa i-800kVA nangaphezulu kwe-oyile-i-transformer. Xa umthamo woqhagamshelwano we-gas relay mkhulu kune-66VA okanye i-15W kunye nokuqokelela kwegesi yi-250 ~ 300ml okanye ngaphakathi koluhlu olubekwe kwisantya seoli, uqhagamshelwano oluhambelanayo kufuneka ludibaniswe. Ubume kunye nokufakela indawo ye-relay yegesi kufuneka ikwazi ukujonga ubungakanani kunye nombala wegesi, kwaye kulula ukuyithatha igesi. Yifake ngokunyuka kwe-1.5% kwi-gradient. I-220kV isigqumathelo setanki ye-oyile yesiguquli kufuneka sibe ne-1 ~ 1.5% yokuthambeka okwandisiweyo.

I-2, i-valve yokukhulula uxinzelelo: isetyenziselwa i-800kVA nangaphezulu kwee-transformers; Xa uxinzelelo kwibhokisi yeoli yokhuseleko lomoya okanye i-valve yokunciphisa uxinzelelo lufikelela kwi-5.07 × 104Pa, kufuneka ikhululwe ngokuthembekileyo. Iivalve ezimbini zokunciphisa uxinzelelo kufuneka zimiselwe i-transformer kunye ne-120000kVA nangaphezulu.

3, ivalve, iplagi yokukhupha umoya: lonke udonga lwetanki yesiguquli kufuneka luxhotyiswe ngevalve yesampulu yeoli, 110kV, 90000kVA kunye ne220kV, 63000kVA nangaphezulu kombindi wodonga lwetanki kufuneka kwakhona ibe nevalve yesampulu yeoli. I-315kVA nangaphezulu iitanki ziya kuba nesixhobo sokukhupha amanzi emazantsi. Indawo engezantsi yetanki ye-transformer kufuneka ibe nkulu ngokwaneleyo ivalve yokukhupha i-oyile, i-220kV i-transformer kufuneka ibe nevalve yokukhupha i-oyile ngengozi. I-transformer kufuneka ikhuphe igesi xa igcwalisa ioli kunye nokuvavanya, ngoko ke inxalenye ephezulu ye-transformer pedestal, i-radiator, i-bushing, njl.
