Inā ʻoi aku ka liʻiliʻi o nā huahana uila ʻike kiʻekiʻe i loko o ka hale, ʻoi aku ka liʻiliʻi o ko lākou hiki ke kū i ka uila ma mua o nā lako uila, pono e hoʻohana i kahipale pale ʻanano ka mālama ʻana i nā huahana uila kiʻekiʻe, a laila pehea e koho ai i kahi surge Pehea e pili ana i nā mea pale?
Ma mua o ke koho ʻana i kahipale pale ʻana, E hōʻoia e hoʻokō i ka uwila paʻi pilikia loiloi a me ka noʻonoʻo i ka hoʻokele waiwai o ka papahana,ʻaʻole wale pololei poho, akā, indirect pōʻino (no ka 'ikepili hooponopono nenoai, indirect poino mea maʻamau kiʻekiʻe ma mua o Eia kekahi, nā kānāwai kūpono a me nā lula. i kēia lā koi i ke kau ʻana onā mea pale hoʻoulu, e like me nā kūlana ʻoihana ʻāina e like me GB 50057. Ma lalo nei, e wehewehe wau pehea e koho ai i kahi pale pale mai nā pae he nui.

I mea e hōʻoia maikaʻi ai ʻaʻole e hōʻeha ʻia nā ʻōnaehana hoʻolako mana paʻakikī a me nā ʻōnaehana ʻike e nā uila uila a me ka piʻi ʻana, wehewehe pono ʻo IEC 62305 i ka wehewehe ʻana o nā wahi palekana uila.

LPZ 0A: Ka ʻike ʻana i nā uila uila, e lawe ana i nā au uila a me nā pā electromagnetic uila.

LPZ 0B: Ka pale ʻana i nā uila uila pololei, me ka pale ʻana i ka ʻāpana uila a i ʻole ke au i hoʻokomo ʻia, a me ke kahua uila uila piha.

LPZ 1: Ka pale ʻana i ka uila uila, ka uila uila kūloko a i ʻole nā ​​au i hoʻokomo ʻia, a me nā māla uila uila.Ua kaupalena ʻia ka piʻi ʻana ma ka palena a pale ʻia e kahi pale pale, a ua pale ʻia ke kahua electromagnetic i ka attenuation.

LPZ 2…n: E like me LPZ 1, akā me ka attenuation hou o ke kahua electromagnetic no ka uila.Ma ke ʻano he lula pale maʻamau, pono e waiho ʻia ka mea i pale ʻia i loko o ka LPZ zone nona nā waiwai electromagnetic i kūpono me ka hiki ke kū i ka pōʻino e hōʻemi i ka pōʻino (ʻino kino, ʻaʻole o ka uila a me nā ʻōnaehana uila ma muli o ka overvoltage, etc.

Pehea e koho ai i ka mea kūponopale pale ʻana

Inā hiki ʻole ke ana i ka papa 1 surge protector (Type1, Class1), hoʻohana maʻamau ʻo Iimp≥12.5kA, ʻo ia hoʻi, lawa ka 12.5kA i ka nui o nā kūlana.Manaʻo mākou e hoʻohana i ka Iimp=25kA, no laila e loaʻa ʻO ka nui o ka hiki, ʻoi aku ka lōʻihi o ke ola lawelawe.

No ka papa 2 pale hoʻonui (Type2, Class2), koho mākou e hoʻohana i ka 20/40kA (In=20kA, Imax=40kA) i nā mea pale hoʻoulu mana, a ʻaʻole i hana pinepine ʻia ka uila ma luna o 40kA (ma hope o LPZ1) i nā noi kikoʻī.o.Nui nā ʻano o ka Papa 2 mau mea pale pale, me 40/80kA, 50/100kA, a me 60/120kA nā mea pale hoʻoulu mana.

E hoʻokō i nā koi palekana ma ʻekolu mau mokuʻāina hana

1. Kūlana kali: nā hiʻohiʻona o ka wā kahiko, ka haʻahaʻa a me nā ʻano pale wela, ka lawe ʻana i kēia manawa o ka pale ʻana i nā awa lua;

2. ʻO ke kūlana hoʻopaʻa haʻahaʻa: Ma waho aʻe o ka ikehu o ka ʻōnaehana e hana ana i ka uila, ʻo ka mea hoʻomalu o ka piʻi ʻana i loaʻa ka ikehu mai ka puʻu uila;

3. TOV moku'āina hana: Ka uila kaumaha o kapale pale ʻanaʻO ka nui o ka volta hana TOV a me kēia manawa.Pili kēia i ka maikaʻi o ka grid, ka mana haʻahaʻa haʻahaʻa haʻahaʻa a me nā ʻōnaehana hoʻoili, nā ʻōnaehana hoʻoili uila uila a me nā ʻano kumu no nā mea hoʻololi hoʻoili.ʻO kēia ka mea e koi ai i ka hiki o ka mea pale pale ke kū i nā overvoltages transient, ʻo ia hoʻi, hiki i ka pale pale ke kū i ka UT i kuhikuhi ʻia i ka maʻamau.

ʻO ka hōʻoia mana ma ka home a ma waho

I ka hopena, he mea koʻikoʻi nō hoʻi ke koho ʻana i nā huahana me ka hōʻoia ʻana o nā ʻaoʻao ʻekolu (e like me CE, TUV, CAS, CQC, a me nā mea ʻē aʻe), a e koho i nā ʻoihana me ka hōʻiliʻili ʻenehana, nā pono ʻenehana, a me nā hopena maikaʻi.

Wahi a TUV, CE, CQC a me nā palapala hōʻoia honua ʻē aʻe, he ʻenehana hana maikaʻi loa ka mea hoʻokele surge a me ka ʻenehana hana i ke kahua o ka pale uila, a hiki ke hoʻokō i nā koi noi ma lalo o nā kūlana koʻikoʻi e like me ke kiʻekiʻe wela, ke kiʻekiʻe wela a me nā wahi pāpū, a hiki ke pale aku i ka manawa harmonic a me ka overvoltage no ka manawa lōʻihi.,ʻO nā mea hoʻomalu hoʻouluhiki ke hoʻopilikinoʻia no nā mea kūʻai ma nā wahi kūikawā.
