7. Cov qauv thiab kev ua haujlwm
Raws li pom nyob rau hauv daim duab (1a) thiab (1b), tus contactor txais ib tug vertically teem configuration, muaj xws li lub tshuab nqus tsev interrupter 3, ib tug insulating thav duab 2, insulators 5, snap act kaw electromagnetic mechanism14, 15,16, mechanical locking mechanism19(for mechanical retention mode), and a base plate11. Cov insulators 5 thiab insulating thav duab 2 muab rwb thaiv tsev thiab cov qauv kev txhawb nqa ntawm qhov siab -voltage circuit thiab hauv av nrog rau ntawm theem. Kev tswj xyuas hluav taws xob muaj xws li choj rectifier seem, kaw coils, qhib coils (rau cov tshuab tuav tswj), tuav coils (rau hluav taws xob tuav hom), auxiliary switches, thiab capacitors. Daim duab hluav taws xob thiab cov kab hluav taws xob muaj nyob hauv daim duab (4a) thiab (4b). Rau hom kev tuav hluav taws xob, qhov tuav lub kauj yog txuas nrog cov kab kaw kom tswj tau tus contactor ntev - lub sijhawm kaw. Cov capacitors tshem tawm cov hluav taws xob hluav taws xob tsim tawm thaum lub sij hawm hloov ntawm kev hloov pauv ib txwm kaw cov neeg nyob hauv lub kaw lus kaw, yog li txhim kho kev ruaj ntseg thiab kev ntseeg siab ntawm cov txheej txheem hloov no.
Thaum tau txais cov lus txib kaw, 110V lossis 220V AC lub zog raug kho los ntawm tus choj rectifier thiab siv rau ob qhov kawg ntawm lub kaw lus. Thaum energized, kaw coil activates lub armature 16, ua rau lub square ncej 17 tsau rau nws tig. Lub caj npab mounted ntawm lub square ncej thawb mus rau pem hauv ntej, tsav lub insulator 5 thiab lub tshuab nqus tsev interrupter3 lub movable conductive pas nrig upward, yog li ua kom tiav contactor kaw.
Rau cov neeg kho tshuab latching mechanism, kaw tuav yog tswj los ntawm cov neeg kho tshuab latching system.
