Dab tsi yog contactor?

Lub contactor yog ib qho kev hloov khoom siv uas siv hluav taws xob, pneumatic, lossis hydraulic cov hauv paus ntsiab lus los tswj qhov qhib thiab kaw ntawm lub ntsiab Circuit Court. Kev siv dav hauv kev lag luam xws li kev lag luam automation thiab lub zog tshiab tsheb, nws feem ntau ua haujlwm los tswj cov khoom siv hluav taws xob xws li hluav taws xob motors thiab vuam tshuab. Tus cwj pwm los ntawm qhov siab tam sim no - tawg muaj peev xwm, kev ua haujlwm sai, thiab kev tswj chaw taws teeb muaj peev xwm, cov contactors nquag siv ua ke nrog fuses. Raws li lawv txoj kev actuation, lawv tuaj yeem muab faib ua hom xws li electromagnetic thiab cov hlau nplaum ruaj khov; Raws li cov arc- tua nruab nrab siv, lawv tau muab faib ua hom xws li cua- tawg thiab nqus.

Lub contactor muaj ib lub tshuab electromagnetic, ib qho kev tiv tauj, thiab ib qho arc -extinguishing device; thaum lub coil yog energized, nws generates ib tug sib nqus quab yuam uas tsav cov neeg mus kaw. Cov hybrid DC contactors tshiab siv los tiv thaiv- cov kab sib txuas thyristors kom ua tiav arc- tsis muaj kev cuam tshuam, thaum cov hlau nplaum ua haujlwm tas mus li yog siv los ntawm lub zog- khaws cia capacitors kom txo tau lub zog noj. Cov contactors ntse muaj kev tiv thaiv kev cuam tshuam tsis raug cai thiab rov pib ua haujlwm, thiab lawv cov txheej txheem ntau- txheej rwb thaiv tsev tsim kom muaj kev nyab xeeb hauv qhov chaw siab -voltage. Lub teb chaws tus qauv GB/T 14048.4-2020 qhia txog ntau hom kev siv-xws li AC-3 thiab AC-4-nrog rau lawv cov sib npaug sib npaug.
