Ukudluliswa kwegesi okubuye kubizwe ngokuthi yi-Buchholz relays kudlala indima kuma-transformers agcwaliswe uwoyela. Lokhu kudluliselwa kwenzelwe ngokukhethekile ukuhlonza nokuphakamisa isexwayiso lapho kutholwa amabhamuza egesi noma omoya kuwoyela we-transformer. Ukuba khona kwegesi noma ama-bubbles emoyeni emafutheni kungaba inkomba yenkinga ngaphakathi kwe-transformer, njengokushisa ngokweqile noma isifunda esifushane. Lapho ithola iphutha i-gas relay izocupha isignali ku-breaker circuit ukuze inqamule futhi ivikele isiguquli ekulimazeni. Le ndatshana ibheka ukuthi kungani ukudluliswa kwegesi kubalulekile kuma-transformer okusabalalisa, ukuthi asebenza kanjani kanye nezinhlobo zawo ezahlukene.
Ukubaluleka Kokudluliswa Kwegesi kuma-Distribution Transformers
Ama-transformer ayisabalalisa ayizingxenye zenethiwekhi yamandla njengoba ehlisa amandla kagesi ukusuka kolayini bokudlulisela kuya kumazinga okusetshenziswa kwasekhaya nakwezentengiselwano. Lawa ma-transformer asebenzisa uwoyela njenge-insulator kanye ne-ejenti yokupholisa. Kodwa-ke amaphutha angavela ngaphakathi kwe-transformer eholela ekwakhekeni kwe-gas noma i-air bubble emafutheni. Lawa mabhamuza angaphazamisa izakhiwo zokuvikela amafutha okuholela emaphutheni kanye nokulimala kwe-transformer.
Ukudluliselwa kwegesi kuklanyelwe ngokuqondile ukukhomba ubukhona begesi noma amabhamuza omoya, kuwoyela we-transformer. Uma kwenzeka iphutha ukudluliselwa kwegesi kuzobonisa ukuthi i-circuit breaker ihambe. Nqamula i-transformer kugridi yamandla ukuvimbela noma yikuphi ukulimala ku-transformer nokuqinisekisa ukuphepha kwesistimu yamandla.
Umgomo Wokusebenza Wokudluliswa Kwegesi
Ukuthunyelwa kwegesi kusebenza ngokusekelwe ezimisweni zokuguquguquka kwegesi. Lapho iphutha elifana nokushisa ngokweqile noma isifunda esifushane kwenzeka ku-transformer gas ikhiqizwa emafutheni. Le gesi iya phezulu ngaphakathi kwe-transformer futhi ingena esikhungweni segesi ukuze ibonwe. Inhloso yalokhu kudluliselana iwukubona noma yimaphi amabhamuza egesi noma omoya emafutheni futhi ithumele isignali ukuze icuphe isinqamuli sesifunda esihlukanisa i-transformer ohlelweni lwamandla.
Izinhlobo Zokudluliswa Kwegesi
Kunezinhlobo ezimbili zamagesi adluliswayo: i-Buchholz relay kanye ne-oyili edluliswayo.
●I-Buchholz Relay
I-Buchholz relay (DIN EN 50216-2) iwuhlobo oluvame kakhulu lokudluliswa kwegesi olusetshenziswa kuma-transformer okusabalalisa. Iqanjwe ngomsunguli wayo, unjiniyela waseJalimane uMax Buchholz, owasungula i-relay ngo-1921.
Umsebenzi:
I-Buchholz relay yakhelwe ukuthola ukunqwabelana kwegesi kanye nokunyakaza okuncane kwamafutha ngaphakathi kwe-transformer. Ngokuyinhloko isetshenziselwa ukuthola amaphutha afana nokwehluleka kokufakwa kwensimbi, ukushisa ngokweqile, noma ukuvuza okuncane okukhiqiza igesi ngaphakathi kukawoyela we-transformer.
Indawo:
Ifakwe epayipini elixhuma ithangi le-transformer eyinhloko nethangi le-conservator.
Isimiso sokusebenza:
Uma igesi ikhiqizwa ngenxa yephutha, iyakhuphuka futhi ingene e-Buchholz relay, isusa uwoyela futhi ibangele ukuba ukuntanta kwehle. Lokhu kwenza kusebenze iswishi ethumela isignali ukuze ihambe i-breaker, ihlukanise i-transformer.
Ukusetshenziswa:
Okuvame ukusetshenziswa kuma-transformer okusabalalisa futhi iyasebenza ekutholeni amaphutha akhula kancane.
●I-Oil Surge Relay
Umsebenzi:
I-oyili edluliswayo iklanyelwe ukubona izinguquko ezingazelelwe ekugelezeni kukawoyela, ezingabonisa amaphutha amakhulu njengokuvuza okukhulu noma amasekethe amafushane kakhulu.
Indawo:
Iphinde ibekwe epayipini eliphakathi kwethangi le-transformer kanye ne-conservator tank, kodwa igxile ekutholeni ukunyakaza kukawoyela ngokushesha kunokunqwabelana kwegesi.
Isimiso sokusebenza:
Ukuqhuma okungazelelwe kokugeleza kwamafutha kubangela ukuntanta ngaphakathi kwe-relay ukuthi kuhambe, kubangele iswishi ethumela isignali ukuze ihambe i-breaker circuit, ihlukanise i-transformer.
Ukusetshenziswa:
Ngokujwayelekile isetshenziswa kuma-transformer amakhulu lapho ingozi yokunyakaza kwamafutha kungazelelwe inkulu.
Ukudla okudlela endlini
Ukudluliselwa kwegesi kudlala indima kuma-transformer okusabalalisa agcwaliswe uwoyela ngokuzwa nokwazisa ngegesi noma amabhamuza omoya kuwoyela we-transformer. Lawa mabhamuza angakhombisa izinkinga, njengamasekethe amafushane. Lapho kutholwa iphutha i-gas relay yenza i-circuit breaker ihlukanise i-transformer ohlelweni lwamandla ukuvimbela ukulimala. Kunezinhlobo ezimbili zama-gas relay; I-Buchholz relay kanye ne-oil surge relay. I-Buchholz relay ivame ukusetshenziswa kuma-transformer okusabalalisa kuyilapho ama-transformer amakhulu asebenzisa i-relay yokwanda kukawoyela.
