Switchgear yog siv nyob rau hauv ntau yam kev lag luam, los ntawm lub zog tsim sector mus rau cov chaw tsim khoom, cov tsev lag luam, thiab lwm yam. Hauv tsab xov xwm no, peb yuav muab cov ntsiab lus ntawm switchgear, nws ua haujlwm li cas, nws hom sib txawv, thiab daim ntawv thov ntawm switchgear hauv kev lag luam sib txawv.

Switchgear yog dab tsi?

Switchgear yog ib qho tseem ceeb ntawm lub zog hluav taws xob. Nws yog ib qho khoom siv hluav taws xob hluav taws xob uas tswj cov hluav taws xob xa mus thiab kev xa tawm. Switchgear yog ib qho kev sib txuas ntawm cov keyboards, fuses, lossis circuit breakers uas siv los tswj thiab tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj.

Switchgear paub los ntawm ntau lub npe nyob rau hauv ntau qhov chaw ntawm lub ntiaj teb no, piv txwv li, nyob rau hauv North America, nws yog hu ua Switchboard, whereas, nyob rau hauv Teb chaws Europe, nws yog hu ua Control Gear. Txawm li cas los xij, lub luag haujlwm tseem ceeb ntawm switchgear tseem zoo ib yam, uas yog los tswj cov hluav taws xob hluav taws xob faib hluav taws xob.

Switchgear ua haujlwm li cas?

Switchgear ua haujlwm raws li lub hauv paus ntsiab lus ntawm kev sib cais hluav taws xob. Nws tuaj yeem yog phau ntawv lossis tsis siv neeg, nyob ntawm qhov kev teeb tsa thiab daim ntawv thov. Thaum lub Circuit Court breaker lossis hloov tau raug kaw, nws tsim ib txoj kev txuas hluav taws xob txuas ntxiv, cia cov hluav taws xob tam sim no dhau los ntawm qhov system. Txawm li cas los xij, thaum qhib Circuit Court breaker lossis hloov pauv, nws cuam tshuam rau txoj kev hluav taws xob, ua rau cov hluav taws xob tsis txaus.

Ib qho tseem ceeb ntawm switchgear yog nws lub peev xwm los cais thiab tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj vim hluav taws xob tsis raug lossis hluav taws xob surges. Thaum muaj teeb meem hluav taws xob los yog lub zog hluav taws xob tshwm sim, lub switchgear pom qhov teeb meem thiab tam sim ntawd cais cov khoom cuam tshuam los ntawm qhov seem ntawm lub zog hluav taws xob, tiv thaiv kev puas tsuaj ntxiv.

Hom Switchgear

Muaj ntau ntau hom switchgear muaj nyob rau hauv kev ua lag luam. Cov hom no txawv raws li lawv daim ntawv thov thiab kev ua haujlwm. Feem ntau hom switchgear yog:

1. Air Insulated Switchgear (AIS)

Cua Insulated Switchgear, abbreviated li AIS, yog ib hom switchgear uas siv cua ua ib qho nruab nrab insulating nruab nrab ntawm cov theem thiab cov hauv av. AIS yog dav siv nyob rau hauv nruab nrab thiab high voltage daim ntaub ntawv.

2. Gas Insulated Switchgear (GIS)

Gas Insulated Switchgear, abbreviated li GIS, yog ib hom switchgear uas siv roj ua ib qho nruab nrab insulating. GIS yog dav siv nyob rau hauv high voltage daim ntaub ntawv, qhov chaw yog txwv, thiab txhim khu kev qha kis tau tus mob yuav tsum tau.

3. High Voltage Switchgear (HV)

High Voltage Switchgear, abbreviated li HV, yog ib hom switchgear uas tau tsim los ua haujlwm ntawm qhov ntsuas hluav taws xob ntawm 72.5 kV thiab siab dua. HV switchgear yog siv dav hauv kev xa hluav taws xob thiab kev faib tshuab.

4. Nruab nrab Voltage Switchgear (MV)

Nruab nrab Voltage Switchgear, luv luv li MV, yog ib hom kev hloov pauv uas tsim los ua haujlwm ntawm qhov ntsuas hluav taws xob ntawm 1 kV txog 72.5 kV. MV switchgear yog siv dav hauv kev lag luam, tsev lag luam, thiab lwm yam kev siv.

Kev siv ntawm Switchgear

Switchgear yog siv nyob rau hauv ntau yam kev lag luam thiab kev siv. Qee qhov kev siv ntau tshaj plaws suav nrog:

1. Kev tsim hluav taws xob thiab kev faib tawm

Switchgear yog siv dav hauv kev tsim hluav taws xob thiab kev faib tshuab. Nws yog siv los tswj, tiv thaiv, thiab cais cov khoom siv hluav taws xob hauv cov chaw tsim hluav taws xob, cov chaw tsim hluav taws xob, thiab lwm qhov chaw tsim hluav taws xob.

2. Cov ntawv thov kev lag luam

Switchgear yog siv nyob rau hauv ntau yam kev lag luam kev siv, los ntawm kev tsim cov nroj tsuag mus rau chemical nroj tsuag, refineries, thiab lwm yam.
