He aha ka Surge Protective Device (SPD)?

ʻO ka Surge Protective Device (SPD) kahi ʻāpana o ka ʻōnaehana pale hoʻonohonoho uila.Hoʻohui like ʻia kēia mea hana me ke kaapuni hoʻolako mana o nā ukana e pono ai ke pale.Hoʻihoʻi hou ka mea pale pale i nā au uila e like me ka manawa hoʻokuʻu inoa mai kahi kaapuni pōkole.Hana ia i ka hoʻohana ʻana i kahi pilina paʻa a i ʻole kahi hoʻololi ea.Eia kekahi, ke lawelawe nei ka mea pale pale ma ke ʻano he mea pani pani palekana no nā kūlana overcurrent a me kahi recloser e hoʻomalu i ka pae uila ma luna o ka volta helu a i ʻole ka haʻahaʻa haʻahaʻa inā loaʻa kahi kūlana hewa.Hiki iā mākou ke hoʻohana i ka mea pale pale ma nā pae āpau o ka pūnaewele lako mana.ʻO kēia ala ka mea maʻamau i hoʻohana pinepine ʻia a ʻoi aku ka maikaʻi o ka pale overvoltage.

ʻO ka mea pale Surge i hoʻopili ʻia i nā hiʻohiʻona impedance kiʻekiʻe.I nā huaʻōlelo ʻē aʻe, ua like ka huina o ka impedance series me ka impedance o kahi mea pale pale surge.Ke ʻike ʻia ka overvoltage transient i loko o ka ʻōnaehana, e emi ana ka impedance o ka hāmeʻa, no laila e hoʻokele ʻia ke au o ka piʻi ʻana ma o ka mea pale pale, me ke kaʻe ʻana i nā mea koʻikoʻi.ʻO ia ka pale ʻana i nā mea hana i nā transients overvoltage a me nā haunaele, e like me nā spike volta a me nā hoʻokele uila, nā ʻano like ʻole, a me nā over-voltage i hoʻokumu ʻia e nā hana hoʻololi a i ʻole ka uila.Ke hoʻokomo ka mea hoʻohana i kahi ʻāpana hoʻoulu a i ʻole kahi mea pale pale i loko o kahi laina mana e hele mai ana mai kahi lako mana e komo pū ana me nā capacitors hoʻoluʻu, ʻaʻole pono nā mea hoʻopau no ka mea ke pale nei kēia mau capacitors mai nā hoʻololi koke ʻana i ka pae uila.
