Nānā nui
ʻO ka Surge arrester kahi ʻano pale overvoltage, kahi i hoʻohana nui ʻia e pale i nā mea uila like ʻole (transformers, switch, capacitors, arresters, transformers, generators, motors, power cables, etc.) ..) ʻO ka pale ʻana o ka overvoltage o ka lewa, ka overvoltage hana a me ka mana pinepine transient overvoltage ke kumu o ka ʻōnaehana insulation coordination.
ʻO ke kumu hana o ka disconnector
Ke hana maʻamau ka mea hopu, ʻaʻole e hana ka disconnector, e hōʻike ana i ka impedance haʻahaʻa, ʻaʻole ia e pili i nā ʻano pale o ka mea hopu.ʻO ka mea hopu me ka disconnector ka palekana, mālama ʻole, kūpono a hilinaʻi.ʻElua ʻano o nā mea hoʻokaʻawale uila: ʻano pahū wela a me ke ʻano hoʻoheheʻe wela.ʻAʻole hiki ke wehe koke ʻia ka mea hoʻoheheʻe wela wela ma muli o kona mau hemahema kumu ponoʻī, no laila ke hoʻohana mau ʻia ka mea hoʻokaʻawale ʻano pahū wela i kēia mau lā.Ua hoʻohana ʻia ka mea hoʻokaʻawale hoʻoheheʻe wela mua e GE ma ke ʻano he silicon carbide valve arrester.ʻO kāna kumu hana ka hoʻopili ʻana i kahi capacitor e like me ka lua o ka hoʻokuʻu ʻana, a kau ʻia ka pahu pahū wela ma ka electrode haʻahaʻa o ka lua hoʻokuʻu.Ke hana maʻamau ka mea hopu, ʻaʻole lawa ka hāʻule o ka uila o ka uila a me ka hana impulse i kēia manawa ma luna o ka capacitor e hana i ka haki ʻana o ka hoʻokuʻu ʻana, a ʻaʻole hana ka disconnector.Ke hoʻopōʻino ka mea hopu ma muli o ka hewa, ʻo ka hāʻule ʻana o ka uila o ka mana alapine hewa o kēia manawa ma ka capacitor e hoʻopau a hoʻokuʻu ʻia ka hoʻokuʻu ʻana, a hoʻomau ka arc i ka wela o ka pahu pahū wela a hiki i ka hana ʻana o ka disconnector.Eia nō naʻe, no nā ʻōnaehana i hoʻopaʻa pono ʻia ma luna o 20A, ʻaʻole hiki i kēia ʻano disconnector ke hōʻoia i ka hana ʻana ma lalo o ka liʻiliʻi o ka mana alapine hewa o kēia manawa.Ke hoʻohana nei ka mea hoʻokuʻu mea hoʻokuʻu wela hou i ka varistor (silicon carbide a i ʻole zinc oxide resistor) i hoʻopili like ʻia ma ka lua hoʻokuʻu, a hoʻokomo ʻia kahi paipu pahū wela ma ka electrode haʻahaʻa.Ma lalo o ka liʻiliʻi o ka mana alapine hewa o kēia manawa, wela ka varistor, hoʻopau i ka paipu pahū wela, a hana ka mea hoʻokuʻu.

1. He māmā i ke kaumaha, liʻiliʻi i ka leo, kū'ē kū'ē, hāʻule hōʻoia a maʻalahi i ka hoʻokomoʻana, a ua kūpono no ka switchgear, apo pūnaewele cabinet a me nā mea hoʻololi'ē aʻe.
2. Hoʻohui pū ʻia ia, me ka ʻole o ka ea, me ka hana hoʻopaʻa maikaʻi ʻana, ka moisture-proof a me ka pahū-hōʻoia, a me ka hana kūikawā.
3. Ka mamao creepage nui, maikaʻi wai repellency, ikaika anti pollution hiki, paʻa hana, a emi ka hana a me ka malama ana.
4. ʻO keʻano kūikawā, ka zinc oxide resistance, ka haʻahaʻa leakage o kēia manawa, ka wikiwiki o kaʻelemakule a me ke ola lōʻihi
5. ʻO ka mana maoli o ka DC reference voltage, ka hawewe nalu huinahā a me ka hoʻomanawanui kiʻekiʻe o kēia manawa ʻoi aku ka kiʻekiʻe ma mua o nā kūlana aupuni a me nā kūlana honua.
Mana pinepine: 48Hz~60Hz

- Ke ana wela: -40°C~+40°C
-Ka makani makani kiʻekiʻe: ʻaʻole ʻoi aku ma mua o 35m/s
-Ke kiʻekiʻe: a hiki i 2000 mika
