Tuatahi, ko nga huanga nui e toru o te kaiwhakataki AC:
1. Ko te AC contactor coil.Cils i te nuinga o te waa ka tautuhia e A1 me A2 ka taea te wehe noa ki nga kaiwhakataki AC me nga kaiwhakataki DC.He maha nga wa ka whakamahia e matou nga kaiwhakataki AC, ko te 220 / 380V te nuinga o te whakamahi:
2. Ko te waahi whakapiri matua o te AC contactor.L1-L2-L3 e hono ana ki te raina whakauru hiko e toru-waahanga, me te T1 T2-T3 e hono ana ki te raina hiko, a ka taea te whakamahi ki te hono i te raina kawenga. Ko nga hoapaki matua o te AC contactor he maha nga hononga tuwhera, te nuinga o te hono ki te ara iahiko matua, hei whakahaere i te tiimata me te mutu o te motuka me etahi atu taputapu!
3. Ko nga hoapaki awhina o te AC contactor.Ko nga hoapaki awhina ka taea te wehewehe ki te waahi tuwhera tonu KORE me te tikanga kati NC.
3-1 I te nuinga o te wa ka tuwhera te tohu KORE, ko te nuinga o nga wa ka tuwhera te tohu KORE e whakamahia ana mo te mana whakahaere kati me te tohu mahi whakawhiti hei whakamahi, penei: Ko te kaiwhakataki AC he maha nga wa ka tuwhera te tohu KORE ki te rama tohu whero ka taea te mahi hei tohu mahi motuka. marama, ina he hiko te contactor AC, maha tuwhera ira KORE katia, tahuri ki runga ki te rama tohu, ki te tuku i te nekeneke mahi iahiko ranei tohu.
3-2, Ira kati noa NC o te AC contactor.Generally, te NC is used for interlocking and signal transmission.
Hei tauira, ka whakamahia e te motuka mana pai me te whakamuri i te mahi honohono o te kaiwhakataki i te waahi kati NC.
Hei tauira, ka hono te AC contactor ira kati kati NC ki te rama tohu kaakaariki, ka taea te mahi hei tohu whakamutu mo te ara iahiko, motika ranei.I te wa e hikohia ana te kaiwhakataki AC, ka momotuhia te waahi kati NC, ka mutu te rama tohu, ka ka te rama tohu mahi, ka rere te ara iahiko.
Tuarua, e mohio ana ahau ki nga huanga o waho o te AC contactor, katahi ka ata titiro ki roto o te AC contactor:
1. Ko nga waahanga matua o te AC contactor: porowhita, matua rino, puna tautuhi, pūnaha whakapā me te armature me etahi atu waahanga.
1. Me mohio noa ki te awhi o te AC contactor.Armature e hono ana i te punaha whakapiri, ka neke te papa ki runga me te heke, ka huri te whakapiri, penei: he maha nga waahi tuwhera KORE kati, he maha nga waahi kati NC ka momotuhia me etahi atu, tenei Ko te whakamahinga taketake!
2. Ko etahi atu waahanga nui: te matua, te porowhita, me te tautuhi i nga puna!
Anei te mahi a nga kaiwhakataki AC i roto i te reo e waatea ana:
I mua i te kore e hikohia te kaiwhakataki AC: kaore e taea te hiko te porowhita, karekau he momi electromagnetic te matua, e kore e neke te armature, ka mau tonu te elasticity o te puna, i tenei wa ka tuwhera te tohu KORE, ka kati te tohu NC kei runga, ko te ahua noa tenei.
AC contactor hiko: coil hiko, rino matua hiko momi hiko, ka taea te hinga i te tautuhi elasticity puna, toia te moka neke ki raro, tenei wa, ka huri te pūnaha whakapā: maha tuwhera ira KORE katia, maha katia ira NC momotuhia, ko te tino tenei mana contactor taketake, contactor is by contact change to indirectly control the circuit!
I muri i te ngaronga o te mana o te AC contactor, ka mutu ranei te hiko, ka kore e hiko te porowhita, kaore he momi electromagnetic i te matua, i tenei wa, ko te elasticity o te puna tautuhi ka peia te tautuhi i te patu, te pupuhi rakau, i tenei wa, ka pana te patu. te pūnaha whakapā o te contactor AC ki te neke, whakahokia ki te āhua tuatahi: te wāhi tuwhera maha KORE momotuhia, te ira maha katia NC katia i runga i.
