ʻO ke kuleana o ka pale pale

ʻO Surge, (Surge Protection Device) he mea pono i ka pale uila o nā lako uila.ʻO ka hana a ka mea pale pale ka palena o ka overvoltage koke e komo i ka laina mana a me ka laina hoʻouna hōʻailona i loko o ka laina uila e hiki ai i nā mea hana a ʻōnaehana paha ke kū, a i ʻole e hoʻokuʻu i ka uila ikaika i loko o ka honua e pale ai i nā lako pale a ʻōnaehana. mai ka poino.pōʻino e ka hopena.

ʻO ke kumu hoʻomalu hoʻoulu

ʻO ke kumumanaʻo hana o ka pale pale ʻana penei: hoʻokomo pinepine ʻia ka pale pale ma nā ʻaoʻao ʻelua o ka mea pale a hoʻopaʻa ʻia.Ma lalo o nā kūlana hana maʻamau, hāʻawi ka mea pale pale i kahi impedance kiʻekiʻe i ka uila alapine o ka mana maʻamau, a aneane ʻaʻohe kahe o kēia manawa, e like me kahi kaapuni hāmama;i ka wā e loaʻa ai kahi overvoltage transient i loko o ka ʻōnaehana, e pane ka mea pale pale i nā overvoltages transient kiʻekiʻe.Hāʻawi ka volta i kahi impedance haʻahaʻa, e like me ka pōkole pōkole i nā mea i pale ʻia.

1. 'Ano ho'ololi: 'O kāna kumu hana 'o ia ka wā 'a'ohe overvoltage hikiwawe, hō'ike ia i kahi impedance ki'eki'e, akā i ka manawa e pane ai i ka overvoltage koke o ka uila, ho'ololi koke kona impedance i ka waiwai ha'aha'a, e hiki ai i ka uila ke hala.Ke hoʻohana ʻia e like me ia mau mea, ʻo nā hāmeʻa e loaʻa: nā kīwaha hoʻokuʻu, nā pahu hoʻokuʻu kinoea, thyristors, etc.

2. Voltage-limiting type: ʻO kāna kumu hana ʻo ia ka impedance kiʻekiʻe inā ʻaʻohe overvoltage koke, akā e hoʻomau ka emi ʻana o kona impedance me ka piʻi ʻana o ka piʻi ʻana o kēia manawa a me ka uila, a ʻo kāna ʻano volage o kēia manawa he ikaika nonlinear.ʻO nā mea i hoʻohana ʻia no ia mau mea: zinc oxide, varistor, suppressor diode, avalanche diode, etc.

3. ʻAno shunt a i ʻole ʻano choke

ʻAno Shunt: i ka like me nā mea i pale ʻia, hōʻike ia i ka impedance haʻahaʻa i nā pulu uila a me ka impedance kiʻekiʻe i nā alapine hana maʻamau.

ʻO ke ʻano Choke: Ma ke ʻano me nā mea i pale ʻia, hōʻike ia i ka impedance kiʻekiʻe i nā pulu uila a me ka impedance haʻahaʻa i nā alapine hana maʻamau.

ʻO nā mea i hoʻohana ʻia e like me ia mau mea: choke coils, high-pass filters, low-pass filters, 1/4 wavelength short-circuiters, a me nā mea like.
