Tsawg-Voltage Circuit Breakers: Kuj hu ua lub tshuab hluav taws xob tsis siv neeg lossis lub tshuab hluav taws xob tsis siv neeg lub tshuab hluav taws xob-thiab tsuas yog hu ua "circuit breakers"-cov no yog cov khoom siv hluav taws xob uas ua haujlwm rau ob qho kev ua haujlwm raws li phau ntawv hloov thaum tseem muab kev tiv thaiv tsis siv neeg tiv thaiv hluav taws xob poob, undervoltage, overload, thiab luv circuits. Lawv tau siv los faib hluav taws xob hluav taws xob, pib lub cev muaj zog asynchronous tsis tu ncua, thiab muab kev tiv thaiv rau cov kab hluav taws xob, lub cev muaj zog, thiab cov khoom siv zoo sib xws. Nyob rau hauv qhov tshwm sim ntawm qhov ua txhaum loj heev-xws li overload, luv Circuit Court, los yog undervoltage- lawv cia li cuam tshuam lub Circuit Court. Ua haujlwm tau zoo, lawv sib npaug rau kev sib koom ua ke ntawm fuse - hom hloov, overload relays, undervoltage relays, thiab thermal relays. Tsis tas li ntawd, lawv feem ntau tsis tas yuav hloov cov khoom tom qab cuam tshuam qhov txhaum tam sim no, thiab vim li ntawd, lawv tau txais ntau daim ntawv thov.
1) Circuit Breaker Accessories
2) Cov Hluav Taws Xob Hluav Taws Xob (MCB): Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob - luv luv li MCBs- yog cov khoom siv dav dav siv ntau tshaj plaws hauv cov khoom siv hluav taws xob hauv lub davhlau ya nyob twg ntawm cov tuam tsev.
3) Moulded Case Circuit Breakers (MCCB): Moulded Case Circuit Breakers muaj peev xwm tuaj yeem cuam tshuam qhov tam sim no thaum twg qhov ntsuas tam sim no tshaj qhov pib mus ncig ua ntej. Lo lus "cov ntaub ntawv molded" yog hais txog kev siv cov ntaub ntawv yas insulating rau lub tsev, ua haujlwm rau hluav taws xob cais cov khoom siv sab hauv los ntawm ib leeg thiab los ntawm cov khoom siv hlau hauv av. MCCBs feem ntau suav nrog cov thermal-Magnetic trip units, thaum cov qauv loj dua feem ntau nruab nrog cov khoom siv-xeev mus txawv tebchaws sensors.
