High-voltage yakazara midziyo (yakakwirira-voltage kugovera kabati) inoreva mukati nekunze AC switchgear inoshanda mumasisitimu emagetsi ane voltages e3kV uye pamusoro uye ma frequency e50Hz uye pazasi.Inonyanya kushandiswa kutonga nekudzivirira kwemasimba emagetsi (kusanganisira magetsi emagetsi, substations, kutumira uye kugovera mitsara, mabhizimisi emabhizimisi nemigodhi, nezvimwewo) Kana mutsara ukakundikana, chikamu chinokanganisa chinokurumidza kubviswa kubva kumagetsi emagetsi, kuitira kuti ave nechokwadi. iyo yakajairika yekushanda kwechikamu chisina kukanganisa chegetsi remagetsi uye kuchengetedzwa kwemidziyo uye kushanda uye kugadzirisa vashandi.Naizvozvo, high-voltage yakakwana michina yakakosha zvikuru yekufambisa uye yekuparadzira midziyo, uye kushanda kwayo kwakachengeteka uye kwakavimbika kune kukosha kukuru kune yakachengeteka uye inoshanda kushanda kwesimba remagetsi.
Yakakwira-voltage yakazara seti yemidziyo inogona kukamurwa kuita:
(1) Zvikamu nemasanganisiro azvo: zvinosanganisira mabreaker breaker, kupatsanura switch, earthing switching, reclosers, circuit breaker, load switch, contactors, fuse uye zviri pamusoro apa Combined load switch-fuse musanganiswa, contactor-fuse (FC) musanganiswa, kupatsanura mutoro. chinja, fuse switch, kuvhura musanganiswa, nezvimwe.
(2) Maseti akazara emidziyo: sanganisa izvo zviri pamusoro uye musanganiswa wazvo nezvimwe zvigadzirwa zvemagetsi (zvakadai sematransformer, emazuvano matransformer, mavoltage transformers, capacitor, reactors, vanosunga, mabara emabhazi, inlet uye outlet bushings, tambo terminals uye chechipiri zvikamu, etc.) Kugadziriswa kunonzwisisika, organically yakabatanidzwa musimbi yakavharwa goko, uye chigadzirwa chine mashandiro akazara ekushandisa.Zvakadai sesimbi-yakavharirwa switchgear (switchgear), gas-insulated metal-enclosed switchgear (GIS), uye high-voltage/low-voltage prefabricated substations.
