Ukuvikeleka Kombani Nokweqisa Kwamandla Ayinhloko

I-GPAS iyisisetshenziswa sokuvikela umbani esisebenza ngezindlela eziningi futhi esisebenzayo esihlanganisa ukucindezelwa okungaba khona kokuhlasela komhlaba kanye nokuvikela i-fault arc. Inganciphisa kakhulu umonakalo kanye nomthelela wokuhlasela okungase kube khona phansi kanye namaphutha e-arc ezintweni zokusebenza lapho echayeke ezingozini zombani.

Lapho umbani oqondile ushaya, induku yombani noma inethiwekhi yokuvikela umbani ixhunyiwe, futhi umbani onamandla ugeleza kugridi yomhlabathi. Uma olayini bamandla kagesi aphezulu bebona ukugcwala kombani, amandla ombani agelezela kugridi yaphansi ngokusebenzisa izibambisi zombani. Lapho imishini yokuphazamisa eqinile efana nemishini yokushisela isebenza, amandla okuphazamisa anamandla akhiqizwa yiwo nawo azogeleza kugridi yomhlabathi. Amandla okugxilisa aqinile angabangela ukulahleka kwedatha, ukusetshenziswa kabi kwempahla, ukukhubeka kwemishini, ukulimala kokufakwa kwensimbi noma ukushiswa kwezinhlelo zokuphakelwa kwamandla kagesi aphansi.

I-GPAS inokwethenjelwa okuphezulu nesikhathi sesenzo esifushane, esingahlukanisa ngokuphumelelayo imisinga yombani wefrikhwensi ephezulu, ivimbele imisinga yombani ekuhlaseleni inethiwekhi evikelayo evikela umbani, futhi igweme ngokuphumelelayo ukwenzeka kwezingozi zokukhiqiza ukuphepha ezifana nemililo nokuqhuma.

Idivayisi ye-LOPS yokucindezela ibhasi ene-voltage ephansi ye-voltage overvoltage ixhunywe ngokuqondile ngokuhambisana nebhasi, isebenzisa ubuchwepheshe obufana nezilawuli ezisheshayo, izilawuli ezingezona umugqa zamandla aphezulu, izinqamuli ze-overvoltage peak, kanye nokucindezelwa kokuhlasela. Ibalwa ngokwesayensi futhi yaklanywa kahle. I-LOPS isebenzisa ngokugcwele izici ezinhle kakhulu ze-volt ampere, umthamo omkhulu oshisayo, kanye nesivinini sokuphendula esisheshayo sezixhumi ze-overvoltage, izinqamuleli ezingezona umugqa, kanye nemishini yokucindezela i-counterattack. Ngokuvamile, ukusetha inani lesenzo se-LOPS izikhathi ezingu-1.2 i-voltage yesigaba sesistimu (engenziwa ngokwezifiso ezimweni ezikhethekile) kungathola imiphumela emihle ngesikhathi sokusebenza.

I-LOPS ixhumeke ngokuqondile ngokuhambisana nebha yebhasi, isebenzisa ubuchwepheshe obufana nezilawuli ezisheshayo, izimelambi ezingezona umugqa zamandla aphezulu, izinqamuli ze-overvoltage peak, kanye nokucindezelwa kokuhlasela. Ibalwa ngokwesayensi futhi yaklanywa kahle. I-LOPS inxephezela ukushiyeka okufana ne-SPD, ukuvikelwa kwe-overvoltage okuhlanganisiwe, nokumuncwa kwamandla okumelana, ukuxazulula ngokuphelele inkinga yokugcwala ngokweqile kubha enkulu ye-voltage emaphakathi.

35kV~6kV olayini abangaphezulu bavame ukufaka izibambi ze-ZnO. Kukhona amaphutha aholela ekukhubekeni, ekwephukeni komugqa kanye nokucisha.
Ukuvikelwa Kombani Okusha Kolayini Wokudluliswa Kombani (LOPT) Kusekelwe kumphumela oseduze we-cathode, ubuchwepheshe bokuvunguza nokucima kwegebe elifushane leleveli eminingi, ukweqa izici ezizwelayo kagesi zezibopheli ze-ZnO, kusebenzisa isimiso sokuvunguza nokucisha kwe-arc yamagumbi amaningi, idizayini yesakhiwo ekhethekile ukuze kwelule futhi kunwetshwe umgomo ogqamile we-arc. ukucisha.

I-LOPT inezinzuzo ezifana nokuphepha, okuthembeke kakhulu, ubude besikhathi eside, kanye nokunakekelwa okuncane. Ingakhulula ngokushesha amandla ombani, ivimbele ukugqashuka kombani kanye nokukhubeka, futhi inemisebenzi yamahhala yesondlo nokuzihlanza.
