Ukuhanjiswa kwegesi okukwabizwa ngokuba zii-Buchholz relays kudlala indima kwi-oyile yokuhambisa ukuhanjiswa kwe-oyile. Ezi relay zenzelwe ngokukodwa ukuchonga kunye nokunyusa isilumkiso xa igesi okanye i-bubbles emoyeni ifunyenwe kwioli ye-transformer. Ubukho begesi okanye i-bubbles emoyeni kwioli ingaba ngumqondiso wengxaki ngaphakathi kwe-transformer, njengokushisa okanye isiphaluka esifutshane. Emva kokubona impazamo i-relay yegesi iya kubangela isignali kwi-breaker circuit ukuze ikhuphe kwaye ikhusele i-transformer engozini. Eli nqaku lijonga ukuba kutheni ukuhanjiswa kwerhasi kubalulekile kwiinguqu zokusasaza, indlela ezisebenza ngayo kunye neentlobo zazo ezahlukeneyo.
Ukubaluleka kokuhanjiswa kwerhasi kwiiTshintsho zokusasaza
Iziguquli zokusasaza ngamalungu othungelwano lwamandla njengoko zinciphisa amandla ombane ukusuka kwiintambo zothumelo ukuya kumanqanaba okusetyenziswa kwekhaya kunye nezorhwebo. Ezi ziguquli zisebenzisa i-oyile njenge-insulator kunye ne-ejenti yokupholisa. Nangona kunjalo iimpazamo zinokuvela ngaphakathi kwe-transformer ekhokelela kwi-gas okanye i-air bubble ukwakheka kwioli. Ezi bhubhu ziyakwazi ukuphazamisa iimpawu ze-insulating zeoli ezibangelwa iimpazamo kunye nomonakalo kwi-transformer.
Ukuhanjiswa kwegesi kulungiselelwe ngokukodwa ukuchonga ubukho begesi okanye iibhubhu zomoya, kwioli ye-transformer. Kwimeko yesiphoso i-relay yegesi iya kubonisa ukuba i-breaker circuit ihambe. Nqamula i-transformer kwigridi yamandla ekhusela nayiphi na ingozi kwi-transformer kunye nokuqinisekisa ukhuseleko lwenkqubo yamandla.
Umgaqo-siseko wokuSebenza weeNgxoxo zeGesi
Ukuhanjiswa kwegesi kusebenza ngokusekwe kwimigaqo yokuguquka kwegesi. Xa iphoso efana nokushisa okanye isiphaluka esifutshane senzeke kwigesi ye-transformer iveliswa kwioli. Le gesi ihambela phezulu ngaphakathi kwe-transformer kwaye ingena kwi-relay yegesi ukuze ibonwe. Injongo yale relay kukubona nayiphi na i-gas okanye i-bubbles emoyeni kwi-oyile kwaye ithumele isignali yokuqalisa i-breaker circuit ihlukanisa i-transformer kwinkqubo yamandla.
Iindidi zeeNgxoxo zeGesi
Kukho iindidi ezimbini zokuhanjiswa kwerhasi: iBuchholz relay kunye ne-oyile egqithiswayo.
●Buchholz Relay
I-Buchholz relay (DIN EN 50216-2) lolona hlobo luqhelekileyo lwe-gas relay esetyenziswa kwii-transformers zokuhambisa. Ithiywe ngegama lomqambi wayo, injineli yaseJamani uMax Buchholz, owaphuhlisa irelay ngo-1921.
Umsebenzi:
I-Buchholz relay yenzelwe ukufumanisa ukuqokelela kwegesi kunye neentshukumo ezincinci zeoli ngaphakathi kwe-transformer. Eyona nto isetyenziselwa ukukhangela iimpazamo ezinje ngokusilela kokugquma, ukufudumeza, okanye ukuvuza okuncinci okuvelisa igesi ngaphakathi kweoyile yesiguquli.
Indawo:
Ifakwe kumbhobho odibanisa itanki enkulu yesiguquli kwitanki yesilondolozi.
UmGaqo wokuSebenza:
Xa igesi iveliswa ngenxa yesiphoso, iyaphakama kwaye ingene kwi-Buchholz relay, isusa ioli kwaye ibangela ukuba i-float iwele. Oku kuvula iswitshi ethumela isignali ukuba ihambe i-breaker circuit, ihlukanise i-transformer.
Ukusetyenziswa:
Ngokuqhelekileyo isetyenziselwa ukusabalalisa i-transformers kwaye iyasebenza ekuboneni iimpazamo ezikhulayo ngokukhawuleza.
●I-Oil Surge Relay
Umsebenzi:
Ukuhanjiswa kwe-oyile ye-oyile kuyilelwe ukufumanisa utshintsho olukhawulezileyo lokuhamba kwe-oyile, olunokuthi lubonise iimpazamo ezinkulu ezifana nokuvuza okukhulu okanye imijikelezo emfutshane enzima.
Indawo:
Ikwabekwe kumbhobho ophakathi kwetanki yesiguquli kunye netanki yesilondolozi, kodwa ugqaliselo lwayo lusekuchongeni intshukumo ekhawulezayo ye-oyile endaweni yokuqokelelana kwerhasi.
UmGaqo wokuSebenza:
Ukunyuka ngokukhawuleza kokuhamba kweoli kubangela ukuba i-float ngaphakathi kwe-relay ihambe, ibangele utshintsho oluthumela umqondiso wokuhamba kwi-breaker circuit, ukwahlula i-transformer.
Ukusetyenziswa:
Ngokuqhelekileyo isetyenziswe kwii-transformers ezinkulu apho umngcipheko wokuhamba kweoli ngokukhawuleza mkhulu.
Yise kude
Ukuhanjiswa kwegesi kudlala indima kwi-oyile yokuhambisa ukuhanjiswa kwe-oyile ngokuva kunye nokwazisa malunga negesi okanye amaqamza omoya kwi-oyile ye-transformer. La maqamza angabonisa imiba, njengeesekethe ezimfutshane. Ekubhaqweni kwesiphoso i-gas relay ivula i-breaker yesiphaluka ukuba ihlukanise i-transformer kwinkqubo yokukhusela ukuthintela ingozi. Kukho iindidi ezimbini zokuhanjiswa kwegesi; Buchholz relay kunye neoli surge relay. I-Buchholz relay iqhele ukusetyenziswa kwi-transformer yokuhambisa ngelixa ii-transformer ezinkulu zisebenzisa ukuhanjiswa kwe-oyile.
