Nyob rau hauvengineering hluav taws xob, adisconnector, disconnect switchorisolator switchis yuav siv los xyuas kom meej tias qhov hluav taws xob Circuit Court yog kiag li de-energized rau cov kev pab los yog txij nkawm. Tej keyboards feem ntau muaj nyob rau hauvtis hluav taws xobthiabmuajdaim ntaub ntawv, qhov twg machinery yuav tau tshem tawm nws qhov uas tsav hwj huam tawm hloov li cas lawm los yog kho. Kev rho tawm High School-voltage keyboards yog siv los hauv hluav taws xob substations apparatus muab xws litej fais fab Circuit Court,transformers, thiab kis kab, rau nkawm. Tus disconnector no mas tsis los rau hauv Circuit Court coj tswj, tiam sis tsuas rau kev rho tawm. Disconnector yuav tsum ua manually los yog txiav (motorized disconnector).
Tsis zoo lithauj khoom keyboardsthiabtej fais fab Circuit Court, disconnectors tsis muaj ib tug mechanism rau hluav ntawmelectric arc, uas tshwm sim thaum conductors teev muaj currents muaj electrically tu ncua. Li no, lawv cov off-load pab kiag li lawm, xav tias yuav tau qhib tau tom qab tam sim no muaj tau tu ncua ntawm tej lwm tswj ntaus ntawv. Kev tswj kev nyab xeeb ntawm lub chaw tso dej yuav tsum tiv thaiv txhua txoj kev los qhib cov disconnector thiab thaum nws khoom siv ib Circuit Court. Qauv kawm nyob rau hauv tej lub teb chaws rau kev nyab xeeb tej zaum yuav tau isolators lub cev muaj zog los yog lockable overloads (uas yuav tau padlocked).
Disconnectors muaj cai rau ib tugntsuas phookom inadvertent zov me nyuam yuav tsis tau (ntawm kev kaw haujlwm-tagout). Hauv lub nruab siab-voltage lossis txoj, no padlocks tej zaum yuav yog ib feem ntawm iblawv cuab yuam qhaibxyuas kom zoo ib theem zuj zus ntawm lub lag luam. Nyob hauv ib co designs, tus tes hloov qhov isolator muaj peev xwm ntxiv musntiaj tebcov raug rho tawm Circuit Court uas muab ntxiv kev nyab xeeb. Muaj tej kev xav hais txog circuits uas inter-txuas lub hwj huam yuav tis uas ob hnub ntawm lub Circuit Court yuav raug rho tawm.
Aswitch disconnectorcombines cov khoom ntawm tus disconnector thiab tus tes hloov qhov load,li ntawd, nws muab lub muaj nuj nqi rho tawm kev ruaj ntseg thaum tau paub hab lov nominal currents.
