Yintoni iswitshi yokuzahlula?Yintoni umsebenzi wesihluli?Indlela yokukhetha?
Isitshixo sokwahlula wonke umntu awayebhekisa kuso yileyo yayivule isango elincinane locelemba.Nqamula unikezelo lwamandla okutshintsha ngokufanelekileyo.Ngaphantsi kombane ophezulu, ukutshintshwa kwe-isolation akufanele kulayishwe.Ukuthuthwa kwesitshixo sokutsalela ngaphakathi kuya kubangela ukungqubana kombane wedwa, ukutsha okungephi, kunye nomonakalo omkhulu ebomini.
I-isolator isetyenziswe ngokubambisana ne-circuit breaker phantsi koxinzelelo oluphezulu lokusebenza.Xa ulungisa indlela, vula kwaye ucime umbane kuqala ukuze uqinisekise ukhuseleko lwabasebenzi bokulondoloza.
Isixhobo sombane sokuhlukanisa iswitshi, iswitshi enye yomhlaba, iswitshi ephindwe kabini yomhlaba, iswitshi yokubopha ibhasi kwisitishi esingaphantsi kwe-11kv.Ukutshintshela ngokungathathi hlangothi.
Umlinganiselo ochanekileyo we-voltage ephezulu ubeka ngokucacileyo ukuba i-grounding switching enye ithetha ukuba xa utshintsho luvaliwe, elinye icala lendlela lisekelwe ukuqinisekisa ukhuseleko.Kuyafana nakwiswitshi yokumisa kabini.Kuyo yonke inkqubo yokucima umbane, i-busbar inokucima amandla ukuze ibe nomsebenzi wokutshintsha amandla, kwaye ukutshintshwa kokungathathi hlangothi kukutshintsha ukusebenza.
Imisebenzi ephambili ye-isolator yile ilandelayo.
1. Xa ugqibezela ukugcinwa kwezixhobo zombane eziphezulu kunye neziphantsi, sebenzisa i-switching yokuhlukanisa ukwahlula iindawo zombane kunye nezingezona zombane, ukudala indawo yokuphazamiseka esekelwe, ukwahlula ukugcinwa kwezixhobo ukusuka kwigalelo elikhulu langoku lenkqubo yokubonelela umbane. , kunye nokuqinisekisa ukugcinwa Ukhuseleko lwabasebenzi kunye nezixhobo zokuhambisa amandla.
2. Umtshini wokuzihlukanisa kunye ne-circuit breaker usebenzisana omnye nomnye ukuguqula ukusebenza kunye nokutshintsha indlela yokusebenza.
① Xa i-circuit breaker yemodyuli ephumayo yeqela elithile leyunithi ivaliwe ngenxa yezinye izizathu, xa i-breaker circuit breaker isetyenziselwa ezinye izinto zokusebenza, ukutshintshela okukodwa kunokukhethwa kwaye kudibaniswe kwisiphaluka solawulo;
② Kwi-wiring evaliweyo, xa isiphaluka esifutshane kuluhlu luvelisa itephu, ukutshintshwa kwe-isolation kungasetyenziselwa ukukhulula i-loop (kodwa qaphela ukuba zonke ii-circuit breakers kolunye uchungechunge kufuneka zibe kwindawo yokuvala);
③Indlela yebhasi ephindwe kabini yecandelo elinye.Xa enye yee-breaker zesekethe ezimbini ze-busway kunye ne-segmented circuit breaker icofa, inokuqhawulwa ngokuhambelana nokutshintsha okukodwa.
Ukuhlelwa kokutshintsha kombane wodwa.
Ukusuka kwindlela yokusebenza yokutshintshwa kombane wokufakelwa kombane, izixhobo zombane ezihlukanisayo zinokwahlulwa zibe zitshintshi ezijikelezayo, ezijikelezayo ngokuthe tye, i-plug-in kunye nezinye izixhobo zombane ezihlukanisayo.Ngokwenani lokutshintsha kombane, ukutshintshwa kombane kunokuthi kwahlulwe kwikholamu enye, ikholamu enye, kunye nezitshixo zokuzihlukanisa zombane zekholamu ezintathu.
Enyanisweni, oku luhlobo lwesixhobo sokutshintsha, esinokudibaniswa okanye sikhutshwe kwi-switching power supply.Kuphela ngamanqaku amancinci amancinci okutshintsha kombane wodwa.Ngokomzekelo, xa umbane wokuhlukanisa umbane uhlukaniswe ube ngamacandelo, kukho umgama ocacileyo ocacileyo phakathi kwee-breaker circuits phakathi kwe-circuit breaker, kwaye iqulethe uphawu olubalulekileyo lokuqhawula.Xa umtshini wokuhlukanisa umbane uvaliwe, umbane wokuhlukanisa umbane unokuthwala yonke into ekhoyo phantsi kweendlela eziqhelekileyo zokulawula iilophu kunye neziganeko ezingaqhelekanga, ezifana neziphoso ezimfutshane kwimeko yeempazamo ezimfutshane phantsi kweemeko eziqhelekileyo kakhulu.
Khetha indlela yokucima amandla kunye nokuvala.Xa umbane ucinyiwe, qala uqhawule i-breaker circuit kwaye uvumele isiphaluka samandla sikhuphe umthwalo.Ukuba akukho mthwalo, qhawula isitshixo sokwahlula.Xa i-wiring, khangela ukuba i-breaker circuit circuit inqanyuliwe., Kuphela xa zonke i-breaker-side side breakers zikwimeko evaliweyo, oko kukuthi, xa ukucima ukuqhawula kuvaliwe kwaye akukho mthwalo, unokuphinda uvale.Emva kokuba umtshini wokuqhawula uvaliwe, i-breaker circuit ingavalwa kwakhona.
