E rua nga Mahi Taketake o nga Rerei Takawaenga i roto i nga Taumahi Mahinga

E rua te nuinga o te whakamahinga o te rei takawaenga e whakamahia ana i roto i te whakamahinga mahi pera i raro nei.

1. toronga whakapā tānga takawaenga, te tikanga whakamahia i roto i te ara iahiko matua te nuinga:
Hei tauira: relay takawaenga whakamahia i roto i te ara iahiko matua, me te AC contactors i roto i te whakarara, whakamahia ki te whakawhānui i te whakapā o AC contactors, hoapā ki te hanga ake mo nga hapa o te whakamahi iti.

2. Ko te wehenga hiko e whakamahia nuitia ana i nga ara iahiko:
Koinei te kaupapa e whakamahia ana e matou: he iti te waa ki te whakahaere i te waa nui, te ngaohiko iti hei whakahaere i te ngaohiko nui, mo te ara iahiko nui o te naianei nui me te wehenga ngaohiko nui.

Rere iti mana whakahuri Photoelectric:
Tuatahi ka whakamahi matou i te relay ki te whakahaere i te whakaoho, ka kati te whakaoho hiko ka tangi, no reira ka whakamahia e matou te reera mana whakahuri whakaahua, na te mea ko te reera mana me whakahaere e matou te relay coil, penei i te pikitia, ka pa atu matou ki te whakawhiti whakaahua. , te mana relay, ka tangi te whakaoho.

Ko te kaupapa mahi o Photoelectric Whakawhiti 220V Plus whakaoho relay takawaenga:
Tuatahi, ko nga waahanga hiko e whakamahia ana i roto i ta maatau hoahoa he 220V, no reira ko te raina hiko ki te kore, ko te raina ahi ki roto i nga hononga tuwhera o te rei i runga ake nei, ka uru nga hoapaki ki roto i te hiko hiko mo te whakaoho.
Waea whakakā Photoelectric, kore ki te whakakā photoelectric, i roto i te whakakā photoelectric maha tuwhera ki relay coil 13, waea ki te relay coil 14, ka pa tatou ki te whakakā photoelectric, photoelectric pana maha tuwhera ira tata.
I tenei wa, ko te mana o te relay coil, he maha nga wa ka kati te whakapiri, me whakatangihia te whakaoho hiko, ka wehe atu tatou i te whakahuri photoelectric, he maha tonu te whakatuwhera i te tohu, te ngaro o te hiko, ka mutu te tangi o te mana whakaoho.
Koinei te huarahi e whakahaere ai te whakawhiti whakaahua hiko i te reera, me te pehea e whakamahia ai te relay i roto i te ara iahiko, e takaro ana i te mahi o te tohu tuku.
