Isiguquli sisebenza ngokuqhubekayo kwezixhobo ze-tuli, ukusebenza okuthembekileyo, amathuba amancinci okusilela.Kodwa ngenxa yokuba uninzi lwenguqulelo lufakelwe ngaphandle, kwaye luyachaphazeleka ngokusebenza komthwalo kunye nefuthe lenkqubo yamandla yesiphaluka esifutshane, ngaphakathi Inkqubo yokusebenza, ngokungathandabuzekiyo zonke iintlobo zeziphene kunye neemeko ezingaqhelekanga.
1. Iimpazamo eziqhelekileyo kunye neziphene zenguqu
2. Ukucwangciswa kokukhuselwa kwesiguquli
3. Ukukhuselwa kombane
(1) Ukukhuselwa kwegesi
(2) Ukukhusela uxinzelelo
(3) ubushushu kunye nokhuseleko oyile kwinqanaba
(4) Kupholile ukhuseleko olupheleleyo
4. Ukhuseleko olwahlukileyo
(1) Magnetizing inrush yangoku sombane
(2) Umgaqo wesibini wokuthintela ukungqinelana
(3) Umahluko ukhuseleko ikhefu ekhawulezileyo
Ngokufutshane ngenisa ezi kukhuseleko oluphambili lwesiguquli, kwaye uqhubeke ngokwazisa ukhuseleko lwesiguquli. Zininzi iindidi zoqwalaselo lokhuselo lokhuselo lwesiguquli. Nantsi intshayelelo emfutshane kwezi ndidi zimbini zokhuselo lokhuselo, ukhuseleko olugqithisileyo kunye nokukhuselwa komhlaba kwisiguquli.
1. Ukhuseleko olugqithisileyo ngoxinizelelo oluphuma ngaphandle
2. Ukukhusela ukukhusela isiguquli
Ukhuseleko lwe-backup lokumisa isiphoso se-short-circuit ze-transformer ezinkulu neziphakathi ngesiqhelo zihlala zibandakanya: ukulandelelana okungaphezulu kokukhusela, ukhuseleko ngokulandelelana kwe-zero, ukhuselo lomsantsa, njl.njl. ingongoma.
(1) Indawo engathathi hlangothi isekwe ngqo
(2) Inqaku elingathathi hlangothi alisekelwanga emhlabeni
(3) Indawo engathathi hlangothi isekwe kwisithuba sokukhupha
Isiguquli sombane esinee-high-high zonke zii-transformer ezingagqitywanga, kwaye ubushushu bomhlaba wekhoyili engathathi hlangothi ibuthathaka kunezinye iindawo. Indawo yokuthintela ukungathathi hlangothi yaphuka ngokulula. Ke ngoko, ukhuseleko lomsantsa kufuneka luqwalaselwe.
Umsebenzi wokhuselo lomsantsa kukhuseleko lokhuselo lobushushu bendawo engathathi hlangothi yendawo engathathi hlangothi yenguqu esiguquliweyo.
Ukhuseleko lwesikhewu luyaqatshelwa ngokusebenzisa umsantsa okhoyo ngoku u-3I0 ohamba ngendlela engathathi hlangothi yesiguquli kunye nevolthi evulekileyo ye-delta 3U0 ye-busbar PT njengemilinganiselo.
Ukuba indawo engathathi hlangothi yesiphoso inyuka iye kwindawo, isithuba siyaqhekeka kwaye kuvela umsantsa omkhulu okhoyo ngoku ongu-3I0. Ngeli xesha, ukhuseleko lwesikhewu luyasebenza kwaye isiguquli sinqunyulwe emva kokulibaziseka. Ukongeza, xa isiphoso somhlaba sivela kwinkqubo, indawo engathathi hlangothi iyazinza kwaye ukhuseleko ngokulandelelana kwe-transformer luyasebenza, kwaye indawo engathathi hlangothi ibekwe kuqala. Emva kokuba inkqubo iphulukene nendawo yomhlaba, ukuba impazamo isekhona, ivolta evulekileyo ye-3U0 ye-busbar PT iya kuba nkulu kakhulu, kwaye ukhuseleko lwesithuba luya kusebenza ngeli xesha.
