Kedu ihe bụ bushes?

Igwe ọkụ eletrik bụ ihe dị mkpa maka akụrụngwa ọkụ eletrik dị iche iche dị ka ihe ngbanwe, ihe mkpuchi shunt na switchgears. Ngwa ndị a na-enye ihe mgbochi mgbochi dị mkpa n'etiti onye na-eduzi ndụ na ahụ na-eduzi ngwa eletrik na ikike ala. Ọrụ a dị oke egwu na-enye ohere maka bushes na-ebu ugbu a na nnukwu voltaji site na ihe mgbochi na-eduzi nke mkpuchi akụrụngwa. Emebere JIEOZU bushings iji gbochie ọdịda eletrik site na ọkụ ma ọ bụ nkupu, iji gbochie ịrị elu okpomọkụ na ọkwa dị ugbu a, yana iguzogide ndị agha sitere na ibu USB na mgbasawanye ọkụ.

Ihe mkpuchi dị n'ime nke ohia ga-anagide nrụgide eletrik nke ọ ga-adịgide na ọrụ. Ihe na-akpata nrụgide ndị a bụ ihe dị iche na voltaji nwere ike ịdị iche site na onye na-eduzi ike ruo n'ihe ndị gbanyere ala n'ọhịa na-agafe. N'ime ngwa ọkara na elu voltaji, mkpuchi nke ime ga-amachikwa mmalite nke mwepu akụkụ (PD) nke nwere ike jiri nwayọọ nwayọọ na-eweda njirimara na ike nke mkpuchi ahụ.

Ihe mkpuchi mpụta nke bushings nwere ihe eji emepụta ihe dị ka ọnụ ọgụgụ nke ụlọ ịwụ na ebe dị anya iji nye nkewa n'etiti ebe njikọ HV na-agba ume yana ikike ala dị na mpụga akụkụ ahụ. Ebumnuche nke njirimara ndị a bụ iji gbochie nkụchi akọrọ (flashover) na creep (leakage). Arcing akọrọ, nke BIL kwadoro, chọrọ anya zuru oke maka bọs iji guzogide mkpali ọkụ eletrik site na ngbanwe na ọkụ na-ada. Ihe omume ndị a nwere ike ime ka ọdịda ọkụ na-egbuke egbuke ebe ọkụ eletrik na-etolite site na onye na-eduzi HV ozugbo na ala ma ọ bụrụ na anya ezughị oke maka voltaji. Ihe na-akpụ akpụ (Leakage) na-apụta mgbe mmetọ na-etolite n'elu ọhịa ma na-enye ụzọ na-eduzi maka ugbu a iji soro n'elu. Ntinye nke shess n'ime ime ohia na-abawanye ogologo elu nke oke ohia n'etiti ọdụ HV na ala iji gbochie mfu na-asọ oyi.

JIEZOU arụpụta ime ụlọ & n'èzí epoxy bushings maka switchgear, transformer & ike ngwa na ma ala na ọkara voltaji klaasị. Emebere ma nwalee Bushings anyị iji zute ụkpụrụ CSA, IEC, NEMA na IEEE dị.

A na-egosi oke ọkụ ọkụ dị ala maka voltaji ruru 5kV/60kV BIL yana oke ọhịa voltaji ọkara maka voltaji ruru 46kV/250kV BIL.

Ịhịa aka n'ahụ maka transformers

Ahịhịa transformer bụ ngwaọrụ mkpuchi nke na-eme ka onye na-ahụ maka ike na-ebu ugbu a gafere site na tank nke mgbada n'ala. Ụdị ụdị mmanya nwere onye nduzi wuru na ya, ebe Draw-Lead ma ọ bụ Draw-Rod Bushing nwere ndokwa maka onye nduzi dị iche ka etinyere site na etiti ya. Mpempe osisi siri ike (ụdị buru ibu) na oke ohia nwere ogo (ụdị condenser) bụ ụdị isi abụọ nke iwu ụlọ:

A na-ejikarị osisi siri ike nwere poselin ma ọ bụ epoxy insulator dị ka ihe njikọ si n'akụkụ ikuku voltaji dị ala nke transformer gaa na mpụga nke transformer.
A na-eji bushes ndị nwere akara ikike na voltaji sistemụ dị elu. E jiri ya tụnyere bushes siri ike, ha dị mgbagwoju anya na owuwu ha. Iji nagide nrụgide ọkụ eletrik dị elu nke a na-emepụta na elu voltaji dị elu, a na-eji ohia nke nwere ike ime ka ọ dị n'ime, bụ nke dị n'etiti etiti na-ebu ihe na-eduzi ugbu a na insulator mpụga. Ebumnuche nke ọta ndị a na-eduzi bụ iji belata nkwụsịtụ site na njikwa ọkụ eletrik gburugburu onye na-eduzi etiti, nke mere na nrụgide ubi na-etinye uche n'otu n'otu n'ime mkpuchi bushes.
