SPD hoʻopaʻa pale T1 moʻo
Nānā huahana
Wahi a GB18802.1, GB50057 a me Q/THQBOO1-2013 maʻamau, pono e hoʻopili ʻia ka ʻaoʻao mua o ka loop SPD i ka moʻo me nā mea hana pale overcurrent e koi ʻia e ka mea hana pale pale.
No ka mea, ʻaʻole hiki i ka fuse a me ka mea hoʻokaʻawale liʻiliʻi i kēia manawa ke hui pū me SPD, ke ʻano ʻino ka mana o ka mana a i ʻole ka pau ʻana o ka SPD, ua pōʻino ke ahi a me nā mea hana e ka uila, ka mea i hoʻopilikia nui i ka hana maʻamau o ka hana!
I kēia manawa, ʻaʻole hiki ke hoʻohālikelike ʻia ka nui o nā mea haʻihaʻi kaapuni liʻiliʻi i hoʻohana pū ʻia me SPD i nā helu ʻehā:
1. He mea maʻalahi loa ka hoʻopōʻino ʻana o ka uila i kēia manawa-ua hāʻule ka pale uila;
2.High koena voltage o ka uila impulse i kēia manawa-ua ho'ēmiʻia ka hilinaʻi o ka uila pale o nā lako;
3. ʻAʻole holo ka mana alapine-free-wheeling-he ʻano ʻole ka lako mana a ke ahi ʻo SPD;
4. ʻO ka hopena o ka uila e hele hewa-ʻaʻole i hāʻule ka pale uila.
I ka nānā ʻana i ke kūlana i kēia manawa ʻaʻohe SPD-specific e kākoʻo ana i kahi mea pale overcurrent i ka ʻoihana pale uila, ma hope o ʻekolu mau makahiki o ka noiʻi a me ka hoʻomohala ʻana a ʻoi aku ma mua o hoʻokahi makahiki o nā ʻano hoʻokolohua hoʻokolohua kūlohelohe i loko o ka hale hana, ua hōʻike ʻia ʻo SPD backup protector. (SCB)
1.SPD mana alapine freewheeling huakaʻi waiwai 4A
2. ʻOi aku ka nui o ka hoʻoulu ʻana i kēia manawa ma mua o 40kA (8/20);
3.Lightning impulse koena kaumaha. E hoʻopau piha i ke kūlana o kēia manawa ʻaʻohe lako pale kūikawā o SPD; ʻO ka hopena pololei o ka hui pū ʻana ma waena o SCB a me SPD ʻo ia ka hōʻoia ʻana ʻaʻole e puhi ʻo SPD i ke ahi a ʻaʻole holo ka hopena o kēia manawa.
Hana a me ka laulā o ka noi
Hoʻopili ʻia ka mea hoʻokaʻawale kūwaho kūikawā SPD ma ke ʻano ma ka loop SPD, a ua hoʻohana ʻia ka mea hoʻokaʻawale ʻokoʻa i loko o kēia manawa no ka ʻike ʻana i ke alapine o ka mana liʻiliʻi i kēia manawa hoʻomaha wikiwiki; ʻAʻole holo ka hopena uila kiʻekiʻe o kēia manawa. Loaʻa i ka hana o ka mana alapine liʻiliʻi i kēia manawa SPD pale ahi a me ka uila hopena SPD pale mau; Hoʻohana wale ʻia nā huahana SCB no ka pale SPD loop overcurrent, a i ʻole ka pale ʻana i kēia manawa. Mai hoʻohana iā lākou i nā manawa ʻē aʻe.

1. ʻO ke ʻano hoʻoheheʻe ʻana i ka palena, hiki ke hoʻomaopopo i ka haʻihaʻi koho ʻana i kēia manawa;
2. He haʻahaʻa ke koena o ka volta o ka impulse, hiki ke hoʻohālikelike ʻia me ka fuse;
3. Hoʻopili ikaika kiʻekiʻe, me ke ola lawelawe lōʻihi;
4. ʻO keʻano micro-broken, liʻiliʻi liʻiliʻi, kūpono no ka hikiʻole o ka mana keʻike i ka SPD;
5. Hoʻopiha i nā kiko'ī, e hoʻokō i nā koi o ke kākoʻoʻana iā SPD ma nā pae T1, T2 a me T3.
