ʻO ka mea hoʻopalekana hoʻoulu ʻana o TRS-B
ʻO ke kumumanaʻo hana o ka mea pale pale:
ʻO nā mea hopu hoʻokuʻu i wehewehe ʻia ʻo SPDs (Surge Protection Devices), he mau mea hana i hoʻolālā ʻia e pale i nā ʻōnaehana uila a me nā mea hana e kūʻē i nā overvoltages transient a impulse e like me nā mea i hana ʻia e ka uila a me ka hoʻololi uila.
ʻO kā lākou hana, ʻo ia ka hoʻohuli ʻana i ka hoʻokuʻu ʻana a i ʻole impulse i hana ʻia e kahi overvoltage i ka honua / ʻāina, no laila e pale ai i nā mea hana i lalo.Hoʻokomo ʻia nā SPD e like me ka laina uila e pale ʻia.Ma ka mains i helu ʻia, ua hoʻohālikelike ʻia lākou me kahi kaapuni hāmama a loaʻa kahi impedance kiʻekiʻe ma ko lākou hopena.Ma ke alo o kahi overvoltage, hāʻule kēia impedance i nā waiwai haʻahaʻa loa, e pani ana i ke kaapuni i ka honua / honua.I ka pau ʻana o ka overvoltage, piʻi koke ko lākou impedance i ka waiwai mua (kiʻekiʻe loa), e hoʻi ana i nā kūlana loop open.
ʻO ka Type 2 SPD ka ʻōnaehana pale nui no nā mea uila uila haʻahaʻa haʻahaʻa.Hoʻokomo ʻia i loko o kēlā me kēia papa hoʻololi uila, pale ia i ka hoʻolaha ʻana o nā overvoltages i nā mea uila a pale i nā ukana.
Hoʻolālā ʻia nā ʻano mea pale pale hoʻoneʻe ʻo Type 2 (SPDs) e pale i nā mea hoʻokomo uila a me nā mea koʻikoʻi e kūʻē i nā piʻi ʻole a me ka hōʻoia ʻana i kahi pae haʻahaʻa haʻahaʻa (Up).
Hāʻawi ʻia nā mea pale ʻano 2 surge i ka pale kūpono i kēia mau ʻano hoʻololi hoʻonāukiuki.Inā ma kahi ʻoihana a i ʻole hale noho, ʻo ka pale ʻano 2 e hōʻoia i ka pale kumu no kāu mau mea hoʻonoho a me nā mea hana.
Loaʻa ka TRS-B,C,D series type 2 SPDs i ka mana hoʻokuʻu o 10kA, 20KA, 40KA, 60KA i ka hoʻonohonoho hoʻokahi-phase a i ʻole 3-phase a me nā ʻano uila like ʻole i mea e pale ai i kekahi ʻano o ka ʻōnaehana lako mana.
Hāʻawi nā hiʻohiʻona THOR Type 2 DIN-rail SPD i ka pane wela wikiwiki a me ka hana ʻoki ʻoki kūpono a hāʻawi i ka palekana wikiwiki a hilinaʻi no nā ʻōnaehana lako mana like ʻole.
Hoʻokumu ʻia me ka hōʻike hewa o ka puka makani a me ka hoʻopili ʻana i ka alarm mamao koho, hiki iā ia ke nānā i ke kūlana hana o ka SPD ponoʻī.
