XML7B MCB Circuit Breaker Bimetallic System
XML7B MCB Circuit Breaker Thermal Tripping Mechanism muaj bimetall sawb, muag kev sib txuas, arc khiav, braid hlau, txav kev sib cuag thiab txav chaw tuav.
Covthermal trippingkev npaj muaj ib tug bimetallic sawb nyob ib ncig ntawm uas lub rhaub coil yog mob los tsim kom sov nyob ntawm seb qhov ntws ntawm tam sim no.
Lub tshuab cua sov tsim tuaj yeem yog ncaj qha qhov twg tam sim no dhau los ntawm bimetal sawb uas cuam tshuam rau ib feem ntawm cov hluav taws xob hluav taws xob los yog tsis ncaj nraim qhov twg lub coil ntawm cov khoom nqa tam sim no raug mob nyob ib ncig ntawm lub bimetallic strip.Lub deflection ntawm ib tug bimetallic sawb activates lub tripping mechanism nyob rau hauv cov ntaub ntawv ntawm tej yam kev mob overload.
Cov strips bimetal yog tsim los ntawm ob yam hlau sib txawv, feem ntau yog tooj dag thiab hlau.Cov hlau no yog riveted thiab welded raws lawv qhov ntev.Cov no yog tsim los xws li tias lawv yuav tsis ua kom sov lub sawb mus rau qhov taw tes tripping rau ib txwm tam sim no, tab sis yog tias qhov tam sim no nce siab tshaj tus nqi, cov sawb tau sov, khoov thiab tawm mus rau lub latch.Bimetallic strips raug xaiv los muab lub sijhawm ncua sijhawm nyob rau hauv qee qhov overloads.
