Ihe mgbaji sekit (ACB)

A na-akpọkwa ihe nbibi sekit nke ụwa niile.A na-etinye akụkụ ya niile n'ime ihe mkpuchi ígwè, nke na-emeghekarị.Enwere ike ịkwado ya na ngwa ngwa dị iche iche.Ọ dị mma iji dochie kọntaktị na akụrụngwa, a na-ejikarị ya eme ihe na isi ngbanwe na njedebe ike.Enwere ntọhapụ elektrọnik, eletrọnịkị na ọgụgụ isi karịa ugbu a.Ihe mgbawa sekit nwere akụkụ anọ nke nchebe: ogologo oge, obere oge, ngwa ngwa na mmebi ala.A na-edozi uru ntọala nke nchedo ọ bụla n'ime otu oke dịka ọkwa shei ya si dị.
Ihe mgbaji sekit a na-adabara na netwọk nkesa nwere AC 50Hz, voltaji nke 380V na 660V, na akara ugbu a nke 200a-6300a.A na-ejikarị ya na-ekesa ọkụ eletrik ma chebe ahịrị na akụrụngwa ọkụ site na oke ibu, undervoltage, obere sekit, ala otu oge na mmejọ ndị ọzọ.Ihe mgbawa sekit nwere ọtụtụ ọrụ nchebe nwere ọgụgụ isi ma nwee ike nweta nchebe nhọrọ.N'okpuru ọnọdụ nkịtị, enwere ike iji ya maka ịgbanwee ahịrị na-adịkarịghị.Enwere ike iji ihe mgbawa sekit dị n'okpuru 1250A iji chebe oke ibu na obere sekit nke moto na netwọk na voltaji AC 50Hz nke 380V.
A na-etinyekwa ihe nbibi sekit ụdị etiti ahụ na isi mgba ọkụ na-apụ apụ, mgbanaka tie ụgbọ ala, nnukwu ọkụ ọkụ feeder na nnukwu njikwa njikwa moto n'akụkụ 400V nke transformer.

Ihe njiri mara ntọala nke ihe nbibi sekit

(1) Egotara voltaji arụ ọrụ Ue

Voltaji na-arụ ọrụ gosiri na-ezo aka na voltaji ọnụ nke ihe mgbawa sekit, nke nwere ike na-arụ ọrụ na-aga n'ihu n'okpuru usoro eji eme ihe na ọnọdụ arụmọrụ akọwapụtara.
China na-ekwu na voltaji na-arụ ọrụ kachasị bụ 1.15 ugboro nke voltaji a kwadoro nke usoro na ọkwa voltaji nke 220kV na n'okpuru;Ọkwa voltaji nke 330kV na n'elu bụ 1.1 ugboro nke voltaji e gosiri dị ka voltaji na-arụ ọrụ kachasị elu.Onye na-agbaji sekit nwere ike idowe mkpuchi n'okpuru voltaji arụ ọrụ kachasị elu nke usoro ahụ, ma nwee ike ime ma mebie dịka ọnọdụ akọwapụtara.

(2) Egosiri ugbu a (na)

Egosiri ugbu a na-ezo aka ugbu a na ntọhapụ nwere ike ịgafe ogologo oge mgbe ọnọdụ okpomọkụ dị n'okpuru 40 ℃.Maka eriri sekit na ntọhapụ a na-agbanwe agbanwe, ọ bụ ihe kachasị ugbu a na ntọhapụ nwere ike ịgafe ogologo oge.
Mgbe ọnọdụ okpomọkụ gafere 40 ℃ mana ọ bụghị elu karịa 60 ℃, a na-ahapụ ya ka ọ belata ibu ma rụọ ọrụ ogologo oge.

(3) Bufee ntọhapụ IR dị ugbu a

Ọ bụrụ na nke ugbu a karịrị uru ntọala IR dị ugbu a nke ntọhapụ, ihe mgbaji sekit ga-egbu oge ntupu.Ọ na-egosipụtakwa oke kachasị ugbu a nke onye na-agbaji sekit nwere ike iguzogide na-enweghị nkwụsị.Uru a ga-abụrịrị ibu karịa IB dị ugbu a mana ọ na-erughị iz kacha ugbu a nke ahịrị kwere.
Enwere ike idozi IR relay disconnect thermal na oke nke 0.7-1.0in, mana ọ bụrụ na ejiri ngwa eletrọnị mee ihe, oke ngbanwe na-ebuwanye ibu, na-abụkarị 0.4-1.0in.Maka onye na-agbaji sekit nke nwere ihe mgbagharị njem na-adịghị agbanwe agbanwe, IR = in.

(4) Mkpịpụta mkpirisi sekit dị ugbu a uru ntọala im

A na-eji relay nke mkpirisi mkpirisi mkpirisi (ozugbo ma ọ bụ obere oge na-egbu oge) iji mebie sekit nke na-agbaji ngwa ngwa mgbe nnukwu mmejọ dị ugbu a na-eme, yana ọnụ ụzọ ọ ga-akwụsị bụ im.

(5) Egobere obere oge na-eguzogide ICW dị ugbu a

Na-ezo aka na uru dị ugbu a ekwenyere ka ọ gafere n'ime oge ekwenyero.Uru dị ugbu a ga-agafe onye nduzi n'ime oge a kwadoro, na onye nduzi agaghị emebi n'ihi oke ọkụ.

(6) Ike imebi

Ikike nke na-agbaji ihe nkesa na-ezo aka n'ikike nke ihe na-eme ka ọ bụrụ nke na-adịghị mma, nke na-abụghị ihe jikọrọ ya na ọkwa ya ugbu a.Enwere 36ka, 50kA na nkọwa ndị ọzọ.A na-ekewakarị ya ka ọ bụrụ ikike imebi obere okirikiri ICU na ikike imebi obere okirikiri ICs.
