Kedu ihe bụ modul Nchaji? Kedu ọrụ nchekwa ọ nwere?

 Modul chaja bụ modul nhazi kachasị mkpa nke ọkụ ọkụ. Ọrụ nchebe ya na-egosipụta na akụkụ nke ntinye n'elu / n'okpuru nchebe voltaji, mmepụta n'elu nchedo voltaji / n'okpuru mkpuchi voltaji, nkwụsịtụ mkpụmkpụ mkpụmkpụ, wdg. Ọrụ ".

1. Gịnị bụ modul chaja?

1) Module chaja na-eme ka usoro ikpo ọkụ na-ekpo ọkụ na-ejikọta onwe ya na ikuku na-ekpo ọkụ, ma na-eme ka ọ dị jụụ na ibu ọkụ, nke kwekọrọ na arụ ọrụ nke usoro ike ahụ n'ezie.

2) Ọ bụ modul nhazi kachasị mkpa nke ọkụ eletrik, a na-ejikwa ya na-enye ike nke substations site na 35kV ruo 330kV.
2. Ọrụ nchekwa nke modul chaja ikuku

1) Ntinye n'elu / n'okpuru nchebe voltaji

Modul ahụ nwere ntinye n'elu / n'okpuru ọrụ nchekwa voltaji. Mgbe ntinye voltaji na-erughị 313 ± 10Vac ma ọ bụ karịa 485 ± 10Vac, a na-echekwa modul ahụ, ọ dịghị mmepụta DC, na ihe nchebe na-egosi (edo edo) dị. Mgbe voltaji ahụ gbakere n'etiti 335 ± 10Vac ~ 460 ± 15Vac, modul na-amaliteghachi ọrụ na-akpaghị aka.

2) Mpụpụ overvoltage nchedo / undervoltage mkpu

Modul ahụ nwere ọrụ nke nchebe nfebigara oke ọkụ yana mkpu n'okpuru voltaji. Mgbe mmepụta voltaji dị ukwuu karịa 293 ± 6Vdc, a na-echekwa modul ahụ, ọ dịghị mmepụta DC, na ihe nchebe (edo edo) na-agbanye. Modul enweghị ike ịgbake na-akpaghị aka, yana modul ahụ ga-agbanyụrịrị wee gbanye ya ọzọ. Mgbe mmepụta voltaji na-erughị 198 ± 1Vdc, modul Mkpu, e nwere DC mmepụta, na nchebe egosi (odo) na-na. Ka eweghachite voltaji ahụ, mpụpụta modul n'okpuru voltaji na-apụ n'anya.

3. Mkpirisi mkpirisi mgbagha

Modul ahụ nwere ọrụ ndọghachi azụ nke mkpirisi okirikiri. Mgbe mpụta modul dị mkpụmkpụ-ekesa, ihe nrụpụta ugbu a adịghị elu karịa 40% nke akara ugbu a. Mgbe e kpochapụrụ ihe nkenke sekit, modul na-eweghachi mmepụta nkịtị na-akpaghị aka.

4. Nchekwa ọnwụ nke oge

Modul ahụ nwere ọrụ nchedo ọnwụ oge. Mgbe ntinye ntinye na-efu, ike nke modul ahụ dị oke, na mmepụta nwere ike ibu ọkara. Mgbe voltaji mmepụta bụ 260V, ọ na-ewepụta 5A ugbu a.

5. N'elu nchedo okpomọkụ

Mgbe a na-egbochi ntinye ikuku nke modul ma ọ bụ ọnọdụ okpomọkụ dị oke elu na okpomọkụ dị n'ime modul ahụ karịrị ọnụ ahịa setịpụrụ, a ga-echebe modul ahụ site na oke okpomọkụ, ihe ngosi nchebe (odo odo) na modul panel ga-adị na ya. , na modul agaghị enwe mmepụta voltaji. Mgbe ọnọdụ ahụ na-adịghị mma kpochapụrụ na okpomọkụ dị n'ime modul ahụ na-alaghachi na nkịtị, modul ga-alaghachi na-arụ ọrụ nkịtị.
6. Nchekwa oke n'akụkụ nke mbụ

N'ọnọdụ na-adịghị mma, ihe na-emebiga ihe ókè na-eme n'akụkụ rectifier nke modul ahụ, a na-echekwa modul ahụ. Modul enweghị ike ịgbake na-akpaghị aka, yana modul ahụ ga-agbanyụrịrị wee gbanye ya ọzọ.
