13KN PW-33-Y High Voltage Pin Type Porcelain Insulator

Wehewehe Huahana

ʻO ka insulator pin kahi mea i hoʻohana ʻia e kākoʻo a hoʻopaneʻe paha i kahi uea a e hana i kahi pale uila ma waena o ka hale kiaʻi a me ka uea [1].Hoʻopili ʻia nā ʻāpana porcelain ceramic insulator maʻamau a me ke kila hoʻolei ʻia me ka hoʻopili sima, a ua uhi ʻia ka ʻili o nā ʻāpana porcelain me kahi papa aniani e hoʻomaikaʻi ai i ka hana insulation o ka insulator.
Pono nā insulators i ka ikaika insulation a me ka ikaika mechanical.I ka wā o ka hana, ʻaʻole hiki i nā insulators ke pale wale i ka hana o ka volta hana a me ka nui o ka volta, akā loaʻa nō hoʻi ke kūpaʻa kūpono i ka erosion o nā haumia kemika, a hiki ke hoʻololi i ka mana o ka hoʻololi ʻana o ka mahana a me ka puni honua.

Hana huahana

ʻO nā waiwai kumu o nā insulators pin e pili ana i ka uila, mechanical a me nā waiwai wela.Eia kekahi, aia ke kū'ē kaiapuni a me ke kū'ē kahiko a me nā waiwai'ē aʻe.

(1) Ka hana uila: Ua kapa ʻia ka hoʻokuʻu ʻana i ka mea luku ma ka ʻaoʻao insulating he flashover, a ʻo ke ʻano flashover ka hana nui o nā insulators.No nā pae uila like ʻole, loaʻa i nā insulators nā koi ʻokoʻa no ka hoʻomanawanui ʻana, e like me ka mana pinepine o ka mana maloʻo a me ka hoʻomaloʻo ʻana i ka uila, ka hoʻomanawanui ʻana o ka uila, ka ʻoki ʻana i ka uila uila, a me ka hoʻomanawanui ʻana i ka hana.I mea e pale aku ai i ka haʻihaʻi ʻana i ka wā o ka hana, ʻoi aku ka kiʻekiʻe o ka volta haʻihaʻi o kahi insulator ma mua o ka uila uila.I ka hoʻāʻo ʻana o ka hale hana, hele maʻamau ka insulator porcelain breakdown i ka hoʻāʻo ʻana, ʻo ia hoʻi, hoʻonui ʻia ka uila kiʻekiʻe e hana pinepine ai i nā huna huna ma ka ʻili insulation, a mālama i kekahi manawa e ʻike inā ua haki ia.Pono kekahi mau insulators e ho'āʻo i ka corona, radio interference test, partial discharge test and dielectric loss test.Ke emi nei ka ikaika uila o nā insulators ma nā wahi kiʻekiʻe ma muli o ka emi ʻana o ka nui o ka ea, no laila pono e hoʻonui ʻia ko lākou kūpaʻa i ka wā e hoʻohuli ʻia i nā kūlana lewa maʻamau.ʻOi aku ka haʻahaʻa o ka uila uila o nā insulators i hoʻohaumia ʻia i ka wā e hoʻopili ʻia ai lākou me ka makū ma mua o ko lākou puʻupuʻu maloʻo maloʻo a pulu.No laila, pono e hoʻoikaika ʻia ka insulation a i ʻole e hoʻohana ʻia nā insulators kū i ka pollution ma nā wahi haumia, a ʻoi aku ka kiʻekiʻe o ka mamao creepage (ka lākiō o ka mamao kolo i ka volta helu) ma mua o nā insulators maʻamau.Ke hoʻohālikelike ʻia me nā insulators AC, ʻo nā insulators DC he haʻahaʻa haʻahaʻa kaila uila, adsorption o ka pollution particles a me ka electrolysis, haʻahaʻa flashover voltage, a maʻamau e koi i ka hoʻolālā kūkulu kūikawā a me ka mamao creepage ʻoi aku ka nui.
