KUSHANDISWA KWESF6 LOAD SWITCH MUDISATION NETWORK

Kushandiswa kweSF6 Load Switch muDistribution Network

Maswichi emagetsi epakati anoshandiswa muzviteshi zvemagetsi zvemahub ese anoshandisa macircuit breaker semidziyo yekudzora nekudzivirira, uye anofanira kunge aine otomatiki inovhara. Zvisinei, kugona kwesimba remagetsi kwechiteshi chega chega chekugovera simba mu ring network kazhinji hakusi kukuru, simba rayo rakayerwa diki pane simba rakayerwa re ring network, uye kuvhura hakudiwi, saka unit yesimba re ring network power distribution station inogona kushandisa chimiro chiri nyore, mutengo wakaderera uye kushanda kwepamusoro. Musanganiswa we load switch + fuse inogona kusangana nezvinodiwa.

Kusanganiswa kwe load switch ne fuse kuti zvitsive circuit breaker yechinyakare kwave kuchiitwa kunze kwenyika kwemakumi mashanu emakore. Chiyero che output ye circuit breakers i1:2.5, iyo ichiri kure kure nenyika dzakabudirira dzemaindasitiri. Zvinoratidzawo kuti munyika mangu, SF6 load switches ine mikana mikuru mukuvandudzwa kwe medium-voltage distribution networks.

Muchidimbu, nekuenzanisa mashandisirwo eSF6 load switches nemacircuit breakers muma small-capacity distribution networks, pfungwa dzinotevera dzinogona kupfupikiswa:

Circuit breaker inoshanda pamwe chete ne relay protection uye ine zvese zvinodiwa

Basa rekudzivirira uye basa rekushanda.

SF6 load switch ine basa rakafanana necircuit breaker, kunze kwekuti haigone kutyora short circuit (haidikanwi).

Kushanda kweSF6 load switch inopwanya transformer isina mutoro kuri nani pane kushanda kwecircuit breaker.

SF6 load switch + current limiting fuse inogonawo kutyora short circuit panguva imwe chete, izvo zvakafanana necircuit breaker.

SF6 load switch + current limiting fuse haina kuipa kupfuura circuit breaker, asi mutengo wayo wakaderera zvikuru.
