ʻO nā mea hoʻomalu o AC Surge

Lai o ka noi

Ua kūpono ʻo SPD i nā ʻano ʻōnaehana haʻahaʻa haʻahaʻa haʻahaʻa me ka uila uila ma lalo o 1000 volts a me ke alapine o 50/60HZ, e like me ka pou a me ke kelepona, nā alahao, nā ʻōnaehana kālā, nā māla aila, nā hale kiʻekiʻe, nā hale a me nā hale keʻena. No ka pale ʻana i nā mea uila (e like me nā kamepiula, nā mea hana a me nā mea hana, nā lako hale, a me nā mea ʻē aʻe) o kēia mau mea hoʻohana i ka uila mai ka uila, overvoltage transient a me nā pōʻino overvoltage ʻē aʻe. E hōʻoia i ka lako a me ka palekana pilikino. He mea pono no ka pale overvoltage.

ʻO ke kumu nui a me ke kumu hana

I loko o ka ʻōnaehana ʻehā ʻāpana ʻekolu, ua hoʻopili ʻia nā mea pale ma waena o nā ʻāpana ʻekolu a me kahi uea kūʻokoʻa i ka uea honua (e nānā i ke kiʻi ma lalo). Ma lalo o nā kūlana maʻamau, aia ka mea pale ma ka mokuʻāina ʻo Levin, a i ka wā e hoʻokau ʻia ai ka mana mana i ka overvoltage ma muli o ka uila a i ʻole nā ​​​​kumu ʻē aʻe. E hoʻohuli koke ʻia ka mea pale i ka manawa nanosecond, e hoʻolauna ana i ka overvoltage surge i ka honua, pēlā e pale ai i nā mea uila ma ka pā mana. Ke hele ka piʻi ʻana o ka overvoltage i ka pale a nalowale, hoʻi hou ka mea pale i ke kūlana kūʻē kiʻekiʻe. I ʻole e hoʻopilikia i ka hana maʻamau o ka mana mana.

4. ʻAʻole ʻoi aku ka nui o ka makemake i ka mokulele kū i ka 5.

5.Where ʻaʻohe ʻike ʻia ka haʻalulu a me ka haʻalulu hopena.

6. ʻAʻohe pōʻino pahū ma ka waena, ʻaʻohe kinoea a me ka lepo(me ka lepo conductive) lawa no ka ʻino ʻana i nā metala a hoʻopau i ka insulationma ka waena.
