Indima ye-disconnectors kwiinkqubo zamandla

Susa unxibelelwanoiiswitshi, ezikwabizwa ngokuba ngabaphuli beesekethe okanye baqhawule uqhagamshelo, zizinto ezibalulekileyo kwiinkqubo zamandla. Zisetyenziselwa ukuhlukanisa amacandelo athile eenkqubo zombane ukuze kugcinwe, ukulungiswa okanye ukutshintshwa. Eli nqaku liza kunika inkcazo yemveliso, lichaze indlela yokusebenzisa ukuqhawula utshintshi, kwaye uxoxe ngeendawo ezisetyenziswa kuzo.

Ingcaciso yeMveliso

A qhawula unxibelelwanoiswitshi yenzelwe ukwaphula uqhagamshelo lombane phakathi kwabaqhubi ababini, ukuqinisekisa ukuba isekethe ikhutshwe ngokupheleleyo ukuze igcinwe okanye ilungiswe. Yintoni eyahlula kwezinye iintlobo zokutshintsha kukukwazi ukubonelela ngesithuba somzimba phakathi kwabaqhubi ababini, ukuhlukanisa umqhubi omnye komnye. Izixhumi azenzi i-arc xa zivuliwe, zizenza ziyimfuneko ekusebenzeni kwisixhobo sombane esiphilayo.

Iziqhawuliziza ngobukhulu obahlukeneyo, umlinganiselo wombane kunye nolungelelwaniso. Banokutshintsha iisekethe ezingatshatanga okanye ezininzi, zibe noqhagamshelwano olubonakalayo okanye olufihliweyo, kwaye lunokusebenza ngesandla okanye ngombane. Ukongezelela, izinto zokukhusela kwi-disconnectors zinquma ukuhamba kwazo, ubushushu abanokumelana nazo, kunye namandla abo omatshini.

sebenzisa iswitshi yokwahlula

Ukuqhawula ukutshintshela kukulungele ukusetyenziswa, kodwa ukusebenza ngokungafanelekanga okanye ukungabi nalwazi kunokukhokelela kwimiphumo emibi. Ngaphambi kokusebenzisa i-isolator, kufuneka kuqinisekiswe ukuba isekethe ilinganiswe ngokuchanekileyo kwi-voltage, ukuba abasebenzisi baqeqeshwe ngokufanelekileyo, kwaye zonke iimfuno zokhuseleko ziyafezekiswa.

Ukusebenzisa iswitshi yodwa, umsebenzisi kufuneka alandele amanyathelo athile afana nokunxiba izixhobo zokukhusela, ukwahlula isekethe, kunye nokutshixa iswitshi ngokwasemzimbeni kwindawo evaliweyo. Oku kuqinisekisa ukuba isekethe i-de-energized ngokupheleleyo kwaye iswitshi ihlukanisa ngokwaneleyo isixhobo okanye inkqubo esebenzayo.

sebenzisa okusingqongileyo

I-Disconnectors isebenza phantsi kweemeko ezinzima kwaye ukusebenza kwazo kunokuchaphazeleka kwizinto ezininzi. Ezi zinto ziquka utshintsho lobushushu, ukufuma, amandla oomatshini kunye neentlobo ezahlukeneyo zongcoliseko. Imiba yokusingqongileyo inokunciphisa ubomi benkonzo ye-disconnector kunye nokudala iingozi zokusebenza ezifana nomlilo okanye ukutshitshiswa kombane.

Ukunciphisa le mingcipheko, i-disconnectors ziyilelwe ukuba zimelane neendawo ezinzima kwaye zivavanywe ngokungqongqo phantsi kweemeko ezahlukeneyo. Baphinde bavavanywe umntu wesithathu ukuqinisekisa ukuba baya kusebenza kakuhle kwiimeko ezahlukeneyo, kubandakanya amaqondo obushushu angaphantsi kwe-zero, ubushushu obugqithisileyo, kunye neemeko ezingqongileyo zekhemikhali.

ukuququmbela

Isishwankathelo, i-disconnector iyinxalenye ebalulekileyo kwinkqubo yamandla, esetyenziselwa ukuhlukanisa iindawo ezahlukeneyo zenkqubo yokugcina nokulungiswa. Zenzelwe ukuphula isekethe ngokwahlula abaqhubi ngokwasemzimbeni kunye nokuqinisekisa ukuba isekethe i-de-energized ngokupheleleyo. Izixhumi ziza ngobukhulu obahlukeneyo, umlinganiselo wombane kunye nolungelelwaniso oluyilelwe ukumelana nemekobume erhabaxa. Iiswitshi zokuzihlukanisa kufuneka zisetyenziswe ngokuchanekileyo, ngokulandela zonke izilumkiso eziyimfuneko zokuqinisekisa ukhuseleko lomsebenzisi kunye nokusebenza okusebenzayo.
