Okwu Mmalite Maka Isi Ihe Mgbanaka

A maara kabinet netwọk mgbanaka dịka SF6 load switch na SF6 load switch + fuse combination ngwa eji na ring network line ma ọ bụ terminal. SF6 load switch bụ ezigbo load switch nke ọtụtụ ndị ọrụ na-enweta n'afọ ndị na-adịbeghị anya. Na mgbakwunye na uru nke ogologo ndụ eletriki, ike mgbawa siri ike na vacuum load switch, uru ya dị mfe ịrụ ọrụ atọ (gbanye, gbanyụọ na ala), obere ọkụ eletrik (inductance, capacitance) imeghe na ịgbaji, yana ikike siri ike iguzogide ọnọdụ gburugburu ebe obibi siri ike. Ọ dị mma ime ka ọ pụta ìhè ma tinye ya na netwọk nkesa voltaji etiti obodo na ime obodo.

A na-ekewa kabinet netwọk mgbanaka n'ụdị abụọ: mkpuchi ikuku na mkpuchi SF6. A na-eji ya maka nkewa na imechi ọkụ eletrik, imepe na ịgbaji ọkụ eletrik dị mkpụmkpụ na transformer enweghị ibu, na chaja ọkụ eletrik nke eriri elu na eriri waya n'ebe dị anya. Ọ na-arụ ọrụ nke njikwa na nchekwa, ọ bụkwa ngwa mgbanwe dị mkpa maka ọkọnọ ike netwọk mgbanaka na ọkọnọ ike ọdụ. N'ime ahụ kabinet, ihe mgba ọkụ eletrik nke nwere mkpuchi ikuku gụnyere ụdị mmepụta gas, ụdị nrụgide na ụdị vacuum. Ihe mgba ọkụ eletrik nke nwere mkpuchi SF6 bụ ụdị SF6. N'ihi na a na-emechi gas SF6 na shei, mgbawa nkewa nke ọ mepụtara anaghị ahụ anya. Ihe mgba ọkụ eletrik na kabinet netwọk mgbanaka na-achọkarị ọdụ atọ, ya bụ, bepụ ibu ahụ, kewapụ sekit ahụ, enwere ike ime ya site na ịkụda ala. Ụdị mmepụta gas, ụdị nrụgide na ihe mgba ọkụ eletrik SF6 dị mfe iru ọdụ atọ, enwere ike ịgbaji naanị ụlọ mgba ọkụ eletrik, enweghị ike ịpụpụ ya, yabụ mgbanwe netwọk vacuum ibu mgbanaka izugbe tupu mgba ọkụ eletrik iji tinye mgba ọkụ eletrik, iji mepụta mgba ọkụ eletrik.

Ihe mgba ọkụ ibu bụ ụdị ngwa mgbanwe nwere ngwaọrụ mgba ọkụ arc dị mfe. A na-akpọ ihe mgba ọkụ ibu nke na-eji gas SF6 dị ka ihe mkpuchi na ihe mgba ọkụ arc a na-akpọ ihe mgba ọkụ ibu SF6. Enwere ike iji ya gbanye ma gbanyụọ ihe mgba ọkụ ibu na ihe mgba ọkụ ibu, a pụkwara iji ya gbanye ma gbanyụọ ahịrị ndị na-enweghị ibu, ihe mgba ọkụ na-enweghị ibu na capacitor, wdg. Ihe mgba ọkụ ibu atọ nwere ọrụ nke ịgbanwu, gbanyụọ na ala nwere njirimara nke nhazi dị mfe na ọnụ ahịa dị ọnụ ala. Naanị ihe mgba ọkụ ibu enweghị ike ịkwụsị ihe mgba ọkụ sekit dị mkpụmkpụ.

Ngwa njikọta SF6 load switch + fuse bụ site na SF6 load switch iji buo overload current (oke overload current maka SF6 load switch ka dị n'ime oke nke load switch rated off current) na mmechi na mmebi nke frequency nkịtị na-arụ ọrụ, ọ chọkwara ibu "transfer current". Fuses voltaji dị elu bụ maka nchekwa sekit dị mkpụmkpụ na nchekwa overload n'akụkụ voltaji dị elu. N'oge a, otu SF6 load switch na fuses atọ nwere ihe mkpali, ma ọ bụrụhaala na ihe mkpali ọ bụla na-eme, usoro njikọ ya ga-eme ka mgbanwe ibu ahụ nwee mgbanwe akpaka atọ. Njikọta nke abụọ ahụ nwere ike izute ihe achọrọ maka nchekwa ọrụ sistemụ nkesa ike n'okpuru ọnọdụ nkịtị na nke njehie.
