ISIMISO ESIYINHLOKO SOKUSHINTSHA UMTHWALO WE-VOLTAGE HIGH

Iswishi yomthwalo we-high-voltage isebenzisa ngokugcwele izinzuzo zokucisha i-arc zeshubhu yokushintsha i-vacuum kanye nendlela yokusebenza ehambisanayo. Njengoba iswishi yomthwalo we-high-voltage ingenalo ikhono lokuphula ugesi we-short-circuit, ilula ngesakhiwo futhi ifaneleka ngezikhathi ezinemisebenzi yamandla amancane kanye nezenzo ezivamile. Kuneziswishi ezimbili ezivamile zomthwalo we-high-voltage: uhlobo lwangaphakathi nohlobo lwekholomu yangaphandle.

Kunezinhlobo eziningi zokushintsha komthwalo we-high-voltage, futhi isakhiwo singahlukaniswa sibe yizinkinobho zomthwalo we-high-voltage kawoyela, izinkinobho zomthwalo we-vacuum high-voltage, izinkinobho zomthwalo we-sulfur hexafluoride high-voltage, izinkinobho zomthwalo we-high-voltage ezikhiqiza igesi kanye nezinkinobho zomthwalo we-high-voltage womoya ocindezelwe, njll.; ngokwendlela yokusebenza, ihlukaniswe ngokusebenza ngesandla Kunezinhlobo ezimbili zokushintsha komthwalo we-high-voltage kanye nezinkinobho zomthwalo we-high-voltage kagesi. Le mikhiqizo igxile kunethiwekhi yokusabalalisa, njengekhabethe lenethiwekhi yendandatho. Njengamanje, izinkinobho zomthwalo we-high-voltage we-vacuum zithandwa kakhulu, kanti izinkinobho zomthwalo we-high-voltage zifakwe ama-fuse neminye imishini. Kuye kwanakwa kakhulu ekuthuthukisweni komsebenzi wokuguqulwa kwenethiwekhi. Okulandelayo kuchaza izici zesakhiwo kanye nezimiso eziyisisekelo zezinkinobho ezimbili ezijwayelekile zomthwalo we-high-voltage.

Iswishi yomthwalo we-voltage ephezulu ifakwe ngokuphelele ku-bracket yayo eqondile. Indlela yayo yokusebenza kufanele isebenze ngendlela ecacisiwe, futhi ikakhulukazi, uma indlela yokusebenza ingugesi noma i-pneumatic, ukusebenza kwayo kufanele kwenziwe nge-voltage encane noma ingcindezi yomoya encane, ngokulandelana, ngaphandle kokuthi ukuphazamiseka kwamandla kagesi kuzothinta imiphumela yokuhlolwa. Esimweni sokugcina, i-voltage noma ingcindezi yomoya ngesikhathi sokusebenza kweswishi yomthwalo kufanele ikhethwe ngaphakathi kobubanzi obucacisiwe ukuze ibe nesivinini esiphezulu kanye nokusebenza okuphezulu kokucima i-arc lapho oxhumana nabo behlukaniswe. Kufanele kuboniswe ukuthi i-switch-disconnector isebenza ngokwanelisayo ngaphansi kwezimo ezingenamthwalo ngaphansi kwezimo ezingenhla. Uma kungenzeka, idatha efana nokuhamba kokuxhumana okuhambayo kufanele iqoshwe. Amaswishi omthwalo angasetshenziswa ngesandla angasetshenziswa ngokuvala okude.

1. Kufanele kucatshangelwe kahle ukukhethwa kokuxhumeka kohlangothi olubukhoma. Uma iswishi yokulayisha ihloselwe ukuxhunywa kumandla kusuka ezinhlangothini zombili, futhi ukwakheka kwangempela kolunye uhlangothi lweswishi yokulayisha kuhlukile kukwakheka kolunye uhlangothi, ukunikezwa kwamandla kwesekethe yokuhlola kufanele kuxhunywe ohlangothini olubonisa izimo zokusebenza ezinzima kakhulu zeswishi yokulayisha. Uma kungabaza, ingxenye yokusebenza kufanele yenziwe ngamandla axhunywe kolunye uhlangothi lweswishi yokulayisha, kanti enye ingxenye yokusebenza kufanele yenziwe ngamandla axhunywe kolunye uhlangothi lweswishi yokulayisha.

2. Ukuhlolwa kokwenziwa nokuphulwa kweswishi yomthwalo we-high-voltage enama-pole amathathu esebenza ngesikhathi esifanayo yi-pole ngayinye kufanele kwenziwe ngezigaba ezintathu ngaphandle kokuthi kuchazwe ngenye indlela.

Ukuhlolwa kokwenziwa nokuphulwa kweswishi enama-pole amathathu ngokusebenza kwe-pole-by-pole (okwakhiwe ngama-switch amathathu ane-single-pole high-voltage load switches) kufanele kwenziwe nge-single-phase, ngaphandle kokuhlolwa kokuphulwa komthwalo we-capacitive okunezidingo ezikhethekile.

3. Ngaphandle kwezinkinobho zomthwalo ezigcwele uketshezi noma igesi kanye nezinkinobho zomthwalo we-vacuum, uma kukhona ukusabalala okukhulu kwelangabi noma kwezinhlayiya zensimbi, kungadingeka ukusebenzisa isikrini sensimbi ukuze sibekwe eduze kwezingxenye eziphilayo futhi kude nazo ngesikhathi sokuhlolwa. Ibanga lokuphepha elichazwe embonini. Izikrini zensimbi, amabakaki kanye nezinye izingxenye ezivame ukuba phansi kufanele zifakwe umswakama emhlabathini futhi zixhunywe komunye nomunye bese zixhunywe kudivayisi efanele yokubeka phansi ukuze kuboniswe ukuthi kukhona yini ukuvuza okukhulu komhlabathi.
