Khoom Taw Qhia:
Hauv hluav taws xob engineering, lub tshuab hluav taws xob disconnector, disconnect switch lossis isolator switch[1] yog siv los xyuas kom meej tias hluav taws xob Circuit Court yog tag nrho de-energised rau kev pab cuam los yog txij nkawm. Xws li cov keyboards feem ntau pom muaj nyob rau hauv hluav taws xob kev faib khoom thiab kev siv hauv kev lag luam, qhov twg cov tshuab yuav tsum muaj nws qhov chaw tsav lub zog tshem tawm rau kev hloov kho lossis kho. High-voltage rho tawm switches yog siv nyob rau hauv hluav taws xob substations tso cai rau kev rho tawm apparatus xws li Circuit Court breakers, transformers, thiab kis kab mob, rau kev kho. Lub disconnector feem ntau tsis yog rau kev tswj xyuas ib txwm muaj ntawm Circuit Court, tab sis tsuas yog rau kev sib cais kev nyab xeeb xwb. Disconnector tuaj yeem ua haujlwm manually lossis txiav (motorized disconnector).
Tsis zoo li cov hluav taws xob hloov hluav taws xob thiab cov hluav taws xob hluav taws xob, cov khoom siv hluav taws xob tsis muaj ib qho kev cuam tshuam ntawm hluav taws xob arc, uas tshwm sim thaum cov khoom siv hluav taws xob muaj hluav taws xob cuam tshuam. Yog li, lawv tau tawm - cov khoom siv thauj khoom, npaj kom qhib tsuas yog tom qab tam sim no tau cuam tshuam los ntawm qee yam khoom siv tswj hwm. Kev ruaj ntseg cov cai ntawm cov nqi hluav taws xob yuav tsum tiv thaiv ib qho kev sim qhib lub disconnector thaum nws muab lub voj voog. Cov qauv hauv qee lub teb chaws rau kev nyab xeeb yuav xav tau lub tshuab hluav taws xob hauv zos lossis cov khoom siv kaw tau ntau dhau (uas tuaj yeem kaw tau).
Disconnectors muaj cov kev cai rau lub ntsuas phoo kom tsis tuaj yeem ua haujlwm tsis tau (lockout-tagout). Hauv siab -voltage los yog complex systems, cov padlocks no tej zaum yuav yog ib feem ntawm ib tug ntxiab -tseem ceeb interlock system los xyuas kom meej raws li zoo raws li kev ua hauj lwm. Hauv qee qhov kev tsim, qhov hloov pauv hloov pauv muaj peev xwm ntxiv rau lub ntiaj teb cov kab hluav taws xob sib cais yog li muab kev nyab xeeb ntxiv. Xws li kev npaj yuav siv tau rau cov circuits uas inter- txuas hluav taws xob faib hluav taws xob qhov twg ob qhov kawg ntawm Circuit Court yuav tsum tau cais tawm.
