Izici zomkhiqizo kanye nendawo yokusebenza

1. I-switchgear inqoba ukushiyeka kwe-switchgear yasekuqaleni.I-switchgear yenoveli yohlobo lwenqola yesandla eyakhiwe yinkampani inemisebenzi yokuvikela ephelele, ukuthembeka okuphezulu kokusebenza, nokugcinwa okulula nokulula.Usayizi omncane nesisindo esincane.
2. Ikhabhinethi yokushintsha yenziwe ikhabethe kanye nenqola yesandla.Ihlukaniswe yaba yigumbi lezinqola eziphathwayo, indawo yokuphuzela amabhasi, igumbi lezintambo, kanye negumbi lokudluliselwa kwempahla ngokuhlukaniswa.Inqola yesandla inezindawo ezimbili zokuhlola nomsebenzi.Igumbi lenqola yezandla lihlukaniswe negumbi lekhebula ngepuleti le-insulating elisuswayo, elilungele futhi eliphephile ngesikhathi sokulungiswa.Izinga lokushintshanisa inqola yesandla ngu-100%, linciphisa isikhathi sokulilungisa futhi lithuthukisa ikhwalithi yokuphakelwa kwamandla.Indlela yesilayidi yenqola ephathwayo inembile futhi iyavumelana nezimo ukuze kuqinisekiswe ukuthi inqola yesandla ayichezuki futhi iphume, futhi isitimela sokuzulazula esimiyo sifakiwe ukuze kwenziwe ipulaki yesibili inembe futhi ixhumeke okuthembekile.
3. Umsebenzi wokuvikela we-switchgear, ngemuva kweminyaka yokusetshenziswa ezimayini zamalahle, umkhiqizo ungahlangabezana nezinketho zokuvikela izinjongo ezahlukahlukene, ezifakwe ukuvuza, ukuqapha ukufakwa kwe-insulation, ukungasebenzi, umjikelezo omfushane, i-overcurrent operation overvoltage, futhi ungasetshenziswa isilawuli kude, ukuxhumana kwerimothi, i-telemetry, njll. Idivayisi ebanzi yokuvikela ezenzakalelayo ingafakwa idivayisi encane yamanje yokukhetha umugqa wokuvikela ophansi.
Uchungechunge lokuvikela i-microcomputer yezimayini kanye namadivayisi wokulinganisa nokulawula angakhethwa.Uhlelo lokuvikela lunokuxhumana okubonakalayo.Lonke ulwazi luthunyelwa kuhlelo lokuqapha olusezingeni eliphezulu noma lokulungisa ngesikhathi sangempela ngenethiwekhi yokuxhumana.Umsebenzi we-"remote Five".

Imisebenzi yokuvikela eyinhloko:
1) Ukuvikelwa kwesifunda esifushane
2) Ukuvikelwa kokugcwala ngokweqile
3) Ukuvikelwa kwe-overcurrent yokulandelana kweZero
4) Ukuvikelwa kwe-overvoltage yokulandelana kweZero
5) Ukuvikelwa kwe-overvoltage kanye ne-undervoltage
Iphinde ibe nemisebenzi efana nenkumbulo yephutha, ukubuza ngamaphutha, nokuzihlola wena.
Izimo zemvelo:
I-switchgear kufanele isebenze ngokujwayelekile ngaphansi kwezimo ezilandelayo:
a) Ukuphakama: 1000m;b) I-ambient
izinga lokushisa: -20℃～40℃;
c) Umswakama ohlobene: 95%;
