I mea e pale aku ai i ka pilikia leakage, ma ka hoʻohui ʻana i ke kahua o kapuʻu hoʻouka, ʻo ke koho ʻana i ka pale leakage he mea nui loa.Wahi a ke kūlana aupuni GB / T 187487.1, pono e hoʻohana ka mea pale leakage o ka puʻu charging type B a i ʻole type A, ʻaʻole ia e pale wale i ka leakage AC, akā pale pū kekahi i ka pulsating DC.ʻO ka ʻokoʻa nui loa ma waena o Type B a me Type A ʻo ia ka Type B i hoʻohui i ka pale mai ka leaka DC.Eia naʻe, ma muli o ka paʻakikī a me ke kumu kūʻai o ka ʻike ʻana i ke ʻano B, koho ka hapa nui o nā mea hana i kēia manawa i ke ʻano A. ʻO ka pōʻino nui loa o ka leakage DC ʻaʻole ia ka hōʻeha pilikino, akā ʻo ka pōʻino huna i hana ʻia e ka hemahema o ka mea pale leakage kumu.Hiki ke ʻōlelo ʻia ʻo ka pale leakage o kēia manawa o ka hoʻopiʻi ʻana i nā puʻu i hūnā i nā pōʻino i ka pae maʻamau.
ʻAno A leakage circuit breaker
ʻO ke ʻano leakage circuit breaker A-type a me ka AC-type leakage circuit breaker he mea like nō ia ma ke ʻano o ka loina hana (ua ana ʻia ka waiwai leakage ma o ka mea hoʻololi o kēia manawa zero-sequence), akā ua hoʻomaikaʻi ʻia nā ʻano magnetic o ka transformer.E hōʻoia i ka hele ʻana ma lalo o nā kūlana:
(a) E like me ke ʻano AC.
(b) Ke koena pulsating DC au.
(c) Hoʻopili ʻia kahi au DC maʻemaʻe o 0.006A ma luna o ke koena pulsating DC.
ʻAno B leakage circuit breaker —— (KINAEVSE hiki ke hana i ka RCD Type B)
Hiki i nā mea ha'i kaapuni leakage type B ke pale pono i nā hō'ailona AC sinusoidal, nā hō'ailona DC pu'upu'u a me nā hō'ailona ma'ema'e, a loa'a iā lākou nā koi ho'olālā ki'eki'e ma mua o nā mea ha'i kaapuni leakage type A.E hōʻoia i ka hele ʻana ma lalo o nā kūlana:
a) E like me ke ʻano A.
b) Koe sinusoidal alternating au i ka 1000 Hz.
c) Ho'opi'i 'ia ke koena o kēia manawa me ka mana'o DC o ka manawa he 0.4 manawa o ka manawa i helu 'ia
d) Hoʻopili ʻia ke koena pulsating DC i kēia manawa me 0.4 mau manawa o ke koena i koho ʻia a i ʻole kahi DC maʻemaʻe o 10mA (ʻoi aku ka nui).
e) Ke koena DC au i hana ʻia e nā kaapuni hoʻoponopono penei:
- ʻelua mau alahaka haʻahaʻa haʻahaʻa haʻahaʻa laina i ka laina no 2-, 3- a me 4 mau pole kaapuni kaapuni leaka honua.
- No 3-mole a me 4-mole honua leakage kaapuni kaapuni, 3 hapalua hawewe pili hoku a 6 hapa-hawewe alahaka.
