He aha kahi mea pale pale surge (SPD)

He aha ka mea pale piʻi? Amea pale piʻi (SPD) he mea hana i hoʻohana ʻia e pale i nā lako uila mai nā piʻi mana a i ʻole nā ​​voltages transient. Hoʻopili ʻia kēia mea hana ma ke kaapuni e like me ke kaapuni mana o ka ukana āna e pale ai. Hiki ke hoʻohana ʻia nā pale piʻi ma nā pae āpau o nā pūnaewele lako mana. Akā he aha ka hana a kahi pale piʻi (SPD)?

ʻO kahi mea pale piʻi he mea pale e kaupalena ana i nā volta transient ma o ka shunting a i ʻole ka palena ʻana i ke au piʻi. I nā huaʻōlelo ʻē aʻe, hana ia e hoʻohuli i ka volta keu mai nā lako uila koʻikoʻi, e like me nā kamepiula, nā kīwī, nā mīkini holoi, a me nā kaapuni palekana, e like me nā ʻōnaehana ʻike ahi a me nā kukui uila ulia pōpilikia. Ua hoʻolālā ʻia kēia mau mea e pale i nā ʻōnaehana uila a me nā lako mai nā hanana piʻi ma o ka palena ʻana i nā volta transient a me ka hoʻohuli ʻana i nā au piʻi. Me ka ʻole o ka pale piʻi SPD kūpono, hiki i nā hanana transient ke hōʻino i nā lako uila a hoʻoulu i nā pilikia downtime pipiʻi.

Hiki i nā piʻi uila ke hele mai mai nā kumu o waho, ʻoi aku ka ikaika mai ka uila, a i ʻole mai loko mai o ka hoʻololi ʻana i ke kaumaha uila. ʻO nā kumu o kēia mau piʻi uila o loko (ʻo ia hoʻi he 65% o nā transients āpau) e komo pū me nā ukana e hoʻohuli a pio ana, ka hana relay a me ka circuit breaker, nā ʻōnaehana hoʻomehana, nā motika, a me nā lako keʻena. He mea nui e hoʻomaopopo he maʻalahi ka hōʻino ʻia o nā lako me nā kaapuni uila koʻikoʻi a me nā hōʻailona mana kiʻiʻoniʻoni a me ke kīwī e nā voltages overload transient. ʻO kēia kahi e komo ai kahi pale piʻi uila, e hāʻawi ana i ka palekana koʻikoʻi no nā mea uila palupalu.

No laila, pehea e hana ai nā pale uila? Ke hana ʻia kahi piʻi mana, ʻike ka pale uila i ka volta keu a hoʻihoʻi palekana iā ia i ka uea honua. Ma ka hana ʻana pēlā, pale ka pale uila i ka volta keu mai ka hiki ʻana a me ka hōʻino ʻana i nā lako uila i hoʻopili ʻia. Ma kēia ʻano, hana nā pale uila ma ke ʻano he pale ma waena o ke kumu mana a me nā mea uila, e hōʻoiaʻiʻo ana ua hoʻemi ʻia kekahi pōʻino hiki mai nā piʻi mana.

I ka hopena, ʻo kahi mea pale uila, a i ʻole kahi mea pale uila (SPD), he ʻāpana koʻikoʻi ia i ka pale ʻana i nā lako uila mai nā piʻi mana a i ʻole nā ​​​​​​voltage transient. He mea nui lākou no ka pale ʻana i nā mea uila koʻikoʻi a me ka pale ʻana i nā pilikia downtime pipiʻi e hiki ke hopena mai nā hanana transient. Ma ka hoʻohuli ʻana i ka voltage keu mai nā lako i hoʻopili ʻia, he kuleana koʻikoʻi nā mea pale uila i ka hōʻoia ʻana i ka hana hilinaʻi a me ka hoʻomau ʻana o nā mea uila. Inā paha e pale ana i nā kamepiula, nā kīwī, a i ʻole nā ​​​​​​ʻōnaehana ʻike ahi, he mea hana pono ʻole nā ​​​​​​mea pale uila no ka mālama ʻana i ka pono o nā lako uila.
