5. Hlau-Clad Switchgear: Hlau-clad switchgear muaj cov khoom siv hauv av, tab sis nrog cov kab rov tav lub tsheb npav loj thiab lwm yam tseem ceeb hauv Circuit Court nyob rau hauv cov khoom sib cais.

Cheebtsam ntawm Switchgear

Switchgear muaj ntau yam khoom siv ua haujlwm ua ke kom muaj kev nyab xeeb hluav taws xob thiab kev ua haujlwm zoo. Nov yog cov ntsiab lus tseem ceeb:

1. Circuit Breakers: Circuit Court breakers yog ua hauj lwm los cuam tshuam qhov txhaum tam sim no los yog hloov tam sim no rau thiab tawm. Lawv ua raws li kev hloov pauv tsis siv neeg, tiv thaiv hluav taws xob los ntawm overloads lossis luv circuits.

2. Disconnect Switches: Disconnect keyboards yog manually ua cov khoom siv rau kev cais tawm. Lawv tso cai rau kev saib xyuas kev ua haujlwm kom ua tau zoo ntawm qhov tshwj xeeb ntawm cov khoom siv hluav taws xob.

3. Fuses: Fuses yog cov khoom siv tiv thaiv uas tshwm sim raws li cov xov hlau nyias lossis ib daim hlab. Thaum qhov tam sim no dhau ntawm qhov kev txwv tsis pub dhau, lub fuse hlau melts, yog li cuam tshuam rau hauv Circuit Court thiab tiv thaiv cov khoom txuas.

4. Relays: Relays yog cov hluav taws xob hluav taws xob hloov hluav taws xob uas qhib lossis tshem tawm cov hluav taws xob hluav taws xob raws li qee yam kev cai ua ntej, xws li overcurrent lossis under-voltage.

5. Bus Bars: Busbars yog cov khoom siv hluav taws xob siv hluav taws xob siv los nqa cov hluav taws xob tam sim no ntawm ntau yam khoom siv hluav taws xob.

6. Tswj Vaj Huam Sib Luag: Lub vaj huam sib luag tswj muaj cov keyboards, ntsuas, thiab lwm yam khoom siv uas xav tau rau kev tuav tswj lossis tsis siv neeg tswj ntawm lub tshuab hloov pauv.

Txoj Cai Ua Haujlwm ntawm Switchgear

Switchgear feem ntau ua haujlwm nyob rau hauv lub hauv paus ntsiab lus ntawm kev xaiv cais cov faulty circuits thiab tiv thaiv kev ua haujlwm. Cia peb nkag siab txog lub hauv paus ntsiab lus ua haujlwm ntawm switchgear:

Kev kuaj xyuas qhov txhaum: Thaum muaj teeb meem tshwm sim hauv lub tshuab hluav taws xob, cov xwm txheej txawv txav xws li overcurrent lossis overvoltage tshwm sim. Ntau yam khoom siv tiv thaiv, xws li relays, sensors, thiab Circuit Court breakers, ntes cov kev txawv txav no.

Teeb liab kis: Qhov teeb meem pom tau pib lub teeb liab kis mus rau lub vaj huam sib luag tswj. Qhov teeb liab no ua rau lub kaw lus tswj kom paub qhov tseeb qhov chaw thiab hom kev ua txhaum.

Kev ua haujlwm ntawm Circuit Breaker: Thaum tau txais qhov teeb meem txhaum cai, lub kaw lus tswj tau qhib lub tshuab hluav taws xob tsim nyog. Lub Circuit Court breaker mus ncig thiab cuam tshuam cov dej ntws tam sim no, cais qhov tsis zoo ntawm cov hluav taws xob.

Fault Clearance: Tom qab cais cov faulty Circuit Court, lub kaw lus tswj xyuas kom meej tias qhov txhaum raug tshem tawm. Thaum qhov kev ua txhaum raug kho lawm, lub kaw lus tswj tau tso cai rau lub Circuit Court breaker rov txuas rau qhov kev sib cais ntawm qhov system.

Kev kuaj thiab kev tu: Switchgear systems yuav tsum tau kuaj thiab saib xyuas kom ntseeg tau tias lawv ua haujlwm zoo. Qhov no suav nrog kev txheeb xyuas qhov kev ua haujlwm ntawm cov hluav taws xob hluav taws xob, kev tiv thaiv hluav taws xob, thiab lwm yam tsis raug.
