mau ʻano ʻāpana i ka hoʻomohala ʻana i nā mea pale pale ʻO nā mea pale Surge nā mea e kaupalena ana i nā overvoltages transient. ʻO nā mea e hana ai i ka pale hoʻoulu ʻana, ʻo ia ka nui o nā ʻāpana hoʻokuʻu kinoea (e like me ka ceramic gas discharge tubes), nā ʻāpana pale uila paʻa (e like me varistors), nā mea pale uila semiconductor (e like me suppression diode TVS, ESD multi-pin ʻāpana) , SCR, etc.). E hoʻolauna mākou i nā ʻano ʻāpana i ka mōʻaukala o ka ʻoihana pale uila: 1. Hoʻopaʻa i ke kaula āpau ʻO ka string gap paʻa he ʻōnaehana hoʻoheheʻe arc maʻalahi. Loaʻa ia i nā electrodes i loko metala i uhi ʻia me ka silicone rubber. Aia nā puka liʻiliʻi ma waena o nā electrodes i loko, a hiki i nā puka ke kamaʻilio me ka ea o waho. Hoʻokumu kēia mau puka liʻiliʻi i kahi moʻo micro Chamber. 2. kaula graphite gap Hana ʻia ka pepa graphite me ka 99.9% carbon content. Loaʻa i ka pepa graphite nā pono kūʻokoʻa ʻaʻole hiki ke hoʻololi ʻia e nā mea metala ʻē aʻe e pili ana i ka conductivity uila a me ka conductivity thermal. Hoʻokaʻawale ʻia ka ʻāpana hoʻokuʻu mai kekahi i kekahi. ʻAʻole hoʻoponopono wale kēia ʻenehana lamination i ka pilikia o ka freewheeling, akā hoʻokuʻu pū kekahi i ka papa ma ka papa, a ʻo ka huahana ponoʻī he mana ikaika loa i kēia manawa. Pōmaikaʻi: nui hoʻokuʻu i kēia manawa ho'āʻo 50KA (maoli ana waiwai) liʻiliʻi leakage o kēia manawa,ʻaʻohe freewheeling i kēia manawa,ʻaʻohe arc hoʻokuʻu, maikaʻi thermal paʻa Nā hemahema: kiʻekiʻe koena uila, lohi manawa pane. ʻOiaʻiʻo, hiki ke hoʻohui ʻia kahi kaapuni hoʻoulu kōkua e hoʻonui ai. Ke hoʻololi nei ke ʻano o ka mea hopu uila, ua loli nui ke anawaena o ka pepa graphite a me ke ʻano o ka graphite. 3. Silicon carbide nā mea pale uila ʻO Silicon carbide kahi huahana i hoʻololi ʻia e like me ka Soviet Union i nā lā mua o ka hoʻokumu ʻia ʻana o ka People's Republic of China. ʻO kāna hana e kaomi a hoʻopaʻa i ke āpau a me kekahi mau papa valve SiC i loko o ka lima porcelain arrester. ʻO ka hana pale ka hoʻohana ʻana i nā hiʻohiʻona nonlinear o ka pā valve SiC. He liʻiliʻi loa ka pale uila, a hiki ke hoʻokuʻu ʻia ka nui o ka uila uila e kaupalena i ke koena o ka uila. Ma hope o ka hala ʻana o ka uila uila, e hoʻonui ʻia ke kūʻē, e kaupalena ana i ka manawa manuahi i loko o nā ʻumi amperes, i hiki ke hoʻopau a hoʻopau ʻia ke āpau. ʻO Silicon carbide arrester ka mea hana uila pale uila nui i kēia manawa me ka mōʻaukala lōʻihi o ka hoʻohana ʻana ma koʻu ʻāina. hana, ʻaʻole piha ka hana pale uila; ʻaʻohe hiki ke hoʻomalu i ka uila uila; maikaʻi ʻole ka paʻa o nā ʻano hana a hiki ke loaʻa i nā pōʻino overvoltage transient; ʻO ke kaumaha o ka hana a he pōkole ke ola lawelawe, a pēlā aku. Ua hōʻike kēia i ka hiki o nā mea hopu carbide silicon ke hoʻohana i nā pōʻino huna a me ka ʻenehana huahana backwardness. 4. ʻO nā ʻāpana pale pale ʻano pila ʻO kāna hana e kaomi a hoʻopaʻa i ke āpau a me nā mea pale (pana ke alakaʻi dioxide a i ʻole emery) i loko o ka lima porcelain arrester. Ke maʻamau ka voltage, hoʻokaʻawale ʻia ke āpau mai ka volta hana. I ka wā e uhaʻi ai ka uila uila i ke āpau, ʻo ke alakaʻi dioxide kahi mea haʻahaʻa haʻahaʻa, kahi e kūpono ai i ka leakage o ka nui o ka uila i loko o ka honua e hōʻemi i ka overvoltage. Aia ke kēpau monoxide, a ua hoʻemi ʻia ka mana alapine freewheeling, no laila e pio ke āpau a hoʻopau ʻia ke au. ʻAʻole kūpono nā hiʻohiʻona pale o ka mea hopu ʻano pila, a ua hoʻololi ʻia e nā mea hopu carbide silicon ma koʻu ʻāina.
