High-voltage switchgear ua haujlwm zoo li tus neeg saib xyuas ntawm lub zog hluav taws xob, lub luag haujlwm rau kev sib txuas, kev sib txuas, thiab kev tiv thaiv circuits.
Cov khoom tseem ceeb muaj xws li:
Circuit Breaker: Lub vanguard ntawm kev tiv thaiv hluav taws xob, cuam tshuam tam sim no sai thaum muaj teeb meem.
Disconnecting Switch: Ib qho cuab yeej pab tau rau kev saib xyuas kev nyab xeeb, muab qhov pom kev cuam tshuam.
Load Switch: Tus neeg ua haujlwm tshaj lij hauv kev ua haujlwm txhua hnub, muaj peev xwm cuam tshuam cov khoom thauj tam sim no.
Grounding Switch: Tus neeg saib xyuas kev nyab xeeb, ua kom ntseeg tau cov khoom siv hauv av.
Cov Khoom Siv Hluav Taws Xob Ua Ke: Txhua yam - rounder, integrating ntau lub zog.
Txhua lub cuab yeej muaj peev xwm tshwj xeeb:
Circuit Court breakers ua tau zoo ntawm kev tuav luv-circuit tam sim no, nrog millisecond- theem kev khiav hauj lwm ceev.
Disconnecting keyboards tsis muaj arc- tua muaj peev xwm tab sis xyuas kom muaj kev nyab xeeb.
Load keyboards poob ntawm ob, haum rau kev ua haujlwm nquag.
Grounding keyboards muab kev tiv thaiv kev nyab xeeb rau cov khoom siv thaum muaj hluav taws xob.
Cov khoom siv hluav taws xob sib xyaw ua ke txuag tau qhov chaw, ua rau lawv tshwj xeeb tshaj yog haum rau cov chaw ua haujlwm me me.
Application Scenarios: Xaiv cov cuab yeej zoo yog zoo li xaiv cov cuab yeej zoo:
Substations: Yuav tsum muaj kev sib txuas ntawm cov hluav taws xob hluav taws xob thiab cov hluav taws xob sib txuas.
Fais fab Faib Faib Kab: Load switches yog kev lag luam thiab siv tau.
Generator Outlets: Yuav tsum muaj - muaj peev xwm Circuit Court breakers.
Cable Ceg Boxes: Cov hloov pauv me me yog txaus.
Ib puag ncig tshwj xeeb: Xav txog cov qauv tsim tshwj xeeb xws li tawg- pov thawj thiab ya raws- pov thawj nta.
