Kapasitọ shunt nwere otu, akpọkọ, outlet porcelain busing, naa. Ukwuu stainless steel akpọkọ na-enye okwu maka iji eji ya, ma ọ bụrụ na enweghị ikpe azụ ma ọ bụrụ na enweghị ikpe ntụkwasị. Iji mee ka ọ ghọta site na voltages dị iche iche, otu na-enwee element n'ime pụtara na series. Kapasitọ na-ekwesite resistor discharge.
Ọmụmaatụ ndị kachasị
Akpọkọ: Akpọkọ cold-pressed, anti-fouling type na-enyere, na creepage distance adịghị kwesịrị 31mm/kV.
Teknụlụjị internal fuse nke nweta.
Site na test, internal fuse na-egosipụta component nke ọchịchị mgbe 0.2ms, energy release site na fault point adịghị kwesịrị 0.3kJ, na component ndị ọzọ nwere onwe ha adịghị enweghị mfe.
Ụdị internal fuse nke advanced, na-eji oil gap arc extinguishing, na-enye ọrụ maka ịhụnanya kapasitọ akpọkọ.
Protection internal fuse na relay protection na-enye standards coordination ziri ezi iji zọpụta ọrụ nke ọma na reliable site na device gọọmenti.
Liquid medium: E ji 100% insulation oil (NO PCB) eji. Liquid a na-enye performance low temperature na partial discharge performance nke ọma.
Insulation main na-enye structure insulation composite, nke na-enye electrical performance nke ọma, ma ọ bụrụ na enweghị strength mechanical nke ọma, nke na-enye ọrụ nke ọma na ọ bụla site na devices complete set of kapasitọ.
Performance sealing nke ọma: Rate leakage annual adịghị kwesịrị 0.1%, na performance sealing nke kapasitọ na-enye site na measures dịka automatic argon arc welding, vacuum leak testing, na thermal aging.
Level discharge partial: Voltage extinguishing adịghị kwesịrị 1.5Un, na enweghị capacitor ọ bụla na-test site na discharge partial site na production.
Parameters
Kapasitọ shunt nke medium voltage/Kapasitọ shunt nke high voltage na-enyere 50Hz ma ọ bụ 60Hz AC power systems iji improve power factor nke power system, reduce line losses, improve quality nke power supply voltage, na increase active output nke transformer.
