Taw qhia rau Circuit Breakers

Lub tshuab hluav taws xob hluav taws xob yog lub tshuab hloov hluav taws xob uas muaj peev xwm ua, nqa, thiab tawg tam sim no nyob rau hauv ib txwm muaj kev cuam tshuam hauv Circuit Court, nrog rau kev ua, nqa, thiab tawg tam sim no nyob rau hauv cov xwm txheej txawv txav hauv lub sijhawm teev tseg. Raws li lawv daim ntawv thov, Circuit Court breakers raug faib ua high-voltage thiab low-voltage hom; Thaum qhov ciam teb ntawm qhov siab thiab qhov hluav taws xob tsawg yog cov kua dej me ntsis, cov khoom siv hluav taws xob ua haujlwm ntawm qhov hluav taws xob siab tshaj 3 kV feem ntau yog categorized li high-voltage apparatus.

Circuit Court breakers pab faib hluav taws xob hluav taws xob, ua kom yooj yim pib ntawm asynchronous motors, 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 faults-xws li hnyav overloads, luv luv Circuit Court, los yog undervoltage tej yam kev mob- lawv cia li cuam tshuam lub Circuit Court. Ua haujlwm zoo, lawv ua raws li kev sib xyaw ua ke ntawm fuse - hloov chav tsev thiab ntau yam kev tiv thaiv relays (xws li, overload, undervoltage, thiab thermal relays). Tsis tas li ntawd, tsis zoo li fuses, lawv feem ntau tsis tas yuav hloov cov khoom tom qab cuam tshuam qhov txhaum tam sim no. Yog li ntawd, lawv tau pom cov ntawv thov thoob plaws hauv ntau qhov chaw.

Nyob rau hauv cov txheej txheem ntawm kev tsim hluav taws xob, kev xa tawm, thiab kev siv hluav taws xob, kev faib hluav taws xob yog ib theem tseem ceeb heev. Lub zog faib hluav taws xob muaj xws li transformers thiab ntau yam siab - thiab qis- cov khoom siv hluav taws xob voltage; ntawm cov no, qhov tsawg-voltage Circuit Court breaker sawv tawm raws li ib qho khoom siv hluav taws xob uas siv los ntawm ntau qhov ntau ntawm cov kev siv dav dav.
