Hoʻopili ka uila i ka pale uila kūwaho a me ka pale uila kūloko. Hoʻohana nui ʻia ka pale uila kūwaho no nā mea loaʻa uila (koʻokoʻo uila, ʻupena pale uila, nā kāʻei pale uila, nā laina pale uila), nā mea alakaʻi i lalo, a me nā hāmeʻa paʻa. ʻO ka hana nui a ka pale pale piʻi e hōʻoia i ka pale ʻana o ke kino o ka hale mai nā uila uila pololei. Hoʻokuʻu ʻia nā uila i kū i ka hale i loko o ka honua ma o nā koʻokoʻo uila (kāʻei, ʻupena, uea), nā mea alakaʻi i lalo, a pēlā pū me ka pale uila i loko o ka pale uila, nā piʻi laina, nā hopena kūwaha honua, ka nalu uila i komo ai, a me ka uila hoʻokomo Hoʻokumu ʻia ke ʻano ma ka hoʻopili paʻa pono ʻana, e pili ana i ka pili pololei a me ka pili pili ʻole ma o SPD, i mea e hana ai ke kino metala, laina laina a me ka honua i kino equipotential conditional, a hoʻohuli ʻia nā wahi kūloko e nā uila a me nā piʻi ʻē aʻe. Hoʻokuʻu ʻia ka uila i kēia manawa a i ʻole ke kolo nui i ka honua e pale ai i ka palekana o ka poʻe a me nā lakohana i ka hale.

ʻĀpana kumu

1. Hoʻokaʻawale puka (ʻike ʻia ma ke āpau pale):

Hoʻohui ʻia ia i ʻelua mau koʻokoʻo hao i hoʻokaʻawale ʻia e kekahi hakahaka i hōʻike ʻia i ka lewa, pili kekahi o ia i ka laina pae mana uila L a i ʻole ka laina kūlike ʻole (N) o ka hāmeʻa pale e pono ai, a me nā koʻokoʻo hao ʻē aʻe a me ka Pili ka laina honua (PE). Ke paʻi ka overvoltage transient, wāwahi ʻia ka hakahaka, a hoʻolauna ʻia kahi ʻāpana o ka hoʻoili overvoltage i ka honua, kahi e pale ai i ka piʻi ʻana o ka uila ma ka hāmeʻa pale ʻia. ʻO ka mamao ma waena o nā koʻokoʻo hao ʻelua o ka hakahaka hoʻokuʻu hiki ke hoʻoponopono ʻia e like me ka mea e pono ai, a maʻalahi ke ʻano, a ʻo ka mea maikaʻi ʻole he maikaʻi ʻole ka hana pio ahi. ʻO ka hakahaka hoʻokuʻu maikaʻi ʻo kahi āpau angular, a ʻoi aku ka maikaʻi o kāna hana arc-extinguishing ma mua o ka mea ma mua. Hoʻokumu ʻia ia e ka hana o ka uila uila F o ke kaapuni a me ka piʻi ʻana o ke kahe wela e kinai i ka arc.

2. Pahu hoʻokuʻu kinoea:

Loaʻa iā ia he mau pā maikaʻi maikaʻi anuanu i hoʻokaʻawale ʻia mai kekahi i kekahi a hoʻopaʻa ʻia i loko o kahi kīʻaha kīʻaha a i ʻole ka pahu keramika i hoʻopihapiha ʻia me kahi kinoea inert (Ar). I mea e hoʻonui ai i ka piʻo kūpono o ka paipu hoʻokuʻu, hāʻawi ʻia kahi agena triggering i loko o ka paipu hoʻokuʻu. ʻO kēia ʻano o ka paipu hoʻopihapiha hoʻopihapiha i loaʻa i ʻelua ʻano kia a me kahi ʻano ʻekolu mau kia.

ʻO nā palena kikoʻī o ka paipu hoʻokuʻu kinoea ʻo: DC voltage voltage Udc; haʻalulu hoʻokuʻu uila Up (Generally, Up≈ (2 ~ 3) Udc; ka mana alapine e kū ai i kēia manawa In; impulse e kū i kēia Ip; kūpale pale R (> 109Ω)); capacitance interelectrode (1-5PF)

Hiki ke hoʻohana ʻia ka ʻōmole hoʻokuʻu kinoea ma lalo o nā kūlana DC a me AC. ʻO kēia ka mea i koho ʻia DC DC Udc penei: E hoʻohana ma lalo o nā kūlana DC: Udc≥1.8U0 (U0 ka uila DC no ka laina e hana maʻamau)

Hoʻohana ma lalo o nā kūlana AC: U dc ≥ 1.44Un (ʻo Un ka helu rms o ka anakahi uila AC no ka hana maʻamau o ka laina)

3.Varistor:

ʻO ia kahi varistor semiconductor varistor mekala me ZnO ma ke ʻano he nui. Ke hoʻopili ka uila i nā wēlau ʻelua i kekahi waiwai, maʻalahi ka pale i ka uila. ʻO kāna kumu hana e kūlike ia i ka moʻo a me ka pili like o ka nui semiconductor PN. Hoʻohālikelike ʻia ka varistor e nā ʻano laina laina maikaʻi ʻole (I = CUα, α kahi coefficient nonlinear), hiki i ke kahe nui (~ 2KA / cm2), haʻahaʻa o ke kahe o ka manawa maʻamau (10-7 ~ 10-6A), uila haʻahaʻa haʻahaʻa (e like me ma I ka uila e hana ana i ka uila a me ke kahe o ke kahe), wikiwiki ka manawa pane i ka overvoltage transient (~ 10-8s), ʻaʻohe freewheeling.

ʻO nā palena ʻenehana o ka varistor ka uila varistor (ʻo ia hoʻi ka hoʻololi uila) UN, voltage voltage Ulma; koena uila Ures; kohu koina anakuhi K (K = Ures / UN); ʻoi loa ka hiki kahe Imax; au kulu; manawa pane.

Hoʻohana ʻia ka varistor ma lalo o nā kūlana aʻe: uila uila: UN ≥ [(√ 2 × 1.2) / 0.7] U0 (U0 ka uila i koho ʻia o ka mana pinepine pinepine ʻia o ka mana)

Anakahi uila kuhikuhi: Ulma ma (1.8 ~ 2) Uac (hoʻohana ʻia ma lalo o nā kūlana DC)

Ulma ≥ (2.2 ~ 2.5) Uac (hoʻohana ʻia ma lalo o nā kūlana AC, ʻo Uac ka uila hana AC)

Pono e hoʻoholo i ka anakahi uila e pili ana i ka varistor e ka voltage ahonui o ka hāmeʻa pale uila. ʻO ke koena uila o ka varistor e haʻahaʻa ma mua o ka pae uila o ka pale uila i pale ʻia, ie (Ulma) max≤Ub / K. Ma hea ʻo K ka lāki uila koena a ʻo Ub ke anakahi uila o ka hāmeʻa pale ʻia.

4. Kaomi diode:

Loaʻa i ka diode suppression kahi hana paʻa-palena. Hana ia i ka ʻāpana breakdown ʻaoʻao.
