Yintoni iukwahlula iswitshi?Yintoni umsebenzi wokutshintsha ukwahlula?njani ukukhetha?Into ebizwaukwahlula iswitshisisitshixo esikhulu semela, esiluhlobo olufakwe emnyango.Ngaba ukucima amandla ngokufanelekileyo.Ngaphantsi kombane ophezulu, umtshintshi wokwahlula akayi kuba nokutshintsha komthwalo.Iiswitshi ezinomthwalo ziya kutsala umva wodwa wombane, ukutsha okungephi kunye nokufa okumandundu.I-Disconnectors isetyenziswe ngokubambisana nabaphuli beesekethe phantsi kombane ophezulu.Xa ulungisa umzila, vula kwaye unqumle amandla ukuze uqinisekise ukhuseleko lwabasebenzi bokulondoloza.Kwisikhululo esingaphantsi kwe-11kv, iswitshi yokwahlula yombane yahlulwe yaba yitshintshi enye yokumisa phantsi, i-double grounding switch kunye ne-bus tie switch.Ukutshintsha okungathathi hlangothi kuvavanyo lwe-voltage ephezulu, into ebizwa ngokuba yi-single grounding switch ithetha ukuba xa uvula kunye nokucima, elinye icala lendlela lisekelwe ukuqinisekisa ukhuseleko.Okufanayo kuya kukutshintsha kabini komhlaba.Ukutshintsha kwebhasi yiswitshi ekhupha ibhasi.Xa ibhasi i-de-energized, i-neutral grounding switch inokudlulisa amandla.Indima ephambili yokuba wedwa yile ilandelayo.1. Kwinkqubo yokugcinwa kwezixhobo zombane eziphezulu kunye neziphantsi, i-switch ye-isolation isetyenziselwa ukwahlula unikezelo lwamandla kunye nenxalenye yombane, ukwenza indawo ecacileyo yokuqhawula, ukwenzela ukuba izixhobo zokugcina zihlulwe kwigalelo lombane. inkqubo yokuqinisekisa ukhuseleko lwabasebenzi bolondolozo kunye nezixhobo zombane.2. Ukuze utshintshe imodi yokusebenza, ukutshintshwa kwe-isolation kunye ne-circuit breaker isebenzisana nomnye ukwenza umsebenzi wokutshintsha.①Xa imodyuli ephumayo yesekethe yesiphaluka ineebhasi ezimbini ezineentambo ezidlulayo ngenxa yezinye izizathu, vala isitshixo kwaye usebenzise i-bypass circuit breaker kunye neminye imisebenzi, iswitshi yokwahlula ingasetyenziselwa ukudibanisa isekethe;② Kwi-wiring evaliweyo, xa uchungechunge lwee-breakers zesekethe luvuliwe kwaye luvaliwe, i-switch disconnect switch ingasetyenziselwa ukukhulula isiphaluka (kodwa nceda uqaphele ukuba zonke ezinye ii-breaker circuit breakers kufuneka zibe kwindawo evaliweyo);③ Kwimowudi ye-wiri ye-busbar yecandelo elinye, xa i-breaker circuit of the two busbar circuit breakers kunye necandelo le-circuit breaker livuliwe okanye livaliwe, isiphaluka sinokuqhawulwa ngokutshintshwa kwe-isolation.Ukuhlelwa kokutshintsha kombane okuhlukanisayo kombane Ukutshintsha kombane kunokwahlulahlula kwiitshintshi zombane ezizimeleyo ezifana nokujikeleza okuthe tye, ukujikeleza okuthe tye, iplagi-in kunye nezinye izitshixo zokuzihlukanisa zombane.Ukutshintshela ukwahlula kombane kunokohlulwa kwikholamu enye, ikholamu ephindwe kabini kunye nekholamu emithathu yokutshintsha umbane wokuzihlukanisa.Enyanisweni, sisitshixo esinokuthi sidibanise okanye sikhuphe amandla.Ezinye iinkcukacha ezincinci zokutshintsha kombane wokuzihlukanisa.Ngokomzekelo, xa umbane wokuhlukanisa umbane ukwi-sub-position, kukho isithuba soqhagamshelwano esicacileyo phakathi kwabafowunelwa, kwaye kukho uphawu olucacileyo lokwahlula.Xa iswitshi yokwahlula yombane ikwindawo evaliweyo, iswitshi yokuhlukanisa yombane inokumelana nemisinga phantsi kwesekethe eqhelekileyo kunye nemigangatho engaqhelekanga, efana neesekethe ezimfutshane phantsi kwemigangatho engaqhelekanga.Umtshini wokuzihlukanisa unqamla unikezelo lwamandla kunye nemodi yokuhambisa amandla, unqumle i-breaker circuit, uvumela isiphaluka ukuba sinqumle umthwalo, sinqumle umtshini wokuzihlukanisa xa kungekho mthwalo, kwaye ukhangele ukuba i-breaker circuit inqanyuliwe.Gubungela umtshintshi wokuqhawula, uze uvale i-breaker circuit
