Nyob rau hauv lub hwj chim system, switchgear yog ib qho tseem ceeb txuas. Lawv tsis tsuas yog tswj cov kev faib tawm thiab kev sib kis ntawm hluav taws xob hluav taws xob, tab sis tseem ua haujlwm tseem ceeb ntawm kev tiv thaiv circuits thiab khoom siv.Hlau clad switchgearthiab gas insulated switchgear (GIS) yog ob hom switchgears, txhua tus muaj nws tus kheej zoo thiab daim ntawv thov scenarios. Kab lus no yuav muab piv rau ob lub switchgears los ntawm ntau yam.
Cov yam ntxwv zoo
Hlau clad switchgear yog tsim los ntawm lub thawv, qhov rooj vaj huam sib luag, hauv paus, rail, fuse, riam hloov thiab lwm yam khoom. Lawv feem ntau yog ua los ntawm cov ntaub ntawv zoo steel phaj, nrog cov dej tsis zoo thiab cov plua plav tsis zoo thiab lub zog ua haujlwm siab, tsim nyog siv rau hauv qhov hnyav hnyav. Hauv qhov sib piv, GIS feem ntau yog tsim los ntawm lub plhaub hlau, roj insulator, cov khoom siv hluav taws xob thiab kev tswj hwm. Nws lub plhaub hlau tuaj yeem tiv taus qhov hluav taws xob siab thiab cov khoom siv hluav taws xob, thiab cov roj insulator muab cov hluav taws xob rwb thaiv tsev zoo.
Kev ua tau zoo
Hlau clad switchgear muaj lub zog txhua yam thiab kev tiv thaiv kev ua haujlwm zoo, tsim nyog siv rau hauv cov khoom siv hluav taws xob tswj thiab kev tiv thaiv hauv kev siv hluav taws xob, kev sib txuas lus, substation thiab transformer. Nws qhov kev ua haujlwm ntawm thiab tawm yog ua tiav los ntawm kev tuav tes lossis cov nyees khawm, thiab kev tswj xyuas hluav taws xob siv hluav taws xob tsawg-voltage DC. GIS paub txog nws lub zog rwb thaiv tsev siab, hneev taw me me, kev ua haujlwm qis thiab kev ntseeg siab. Cov roj insulator ntawm GIS tuaj yeem muab lub zog rwb thaiv tsev zoo heev, tso cai rau cov khoom siv los tiv thaiv cov hluav taws xob siab, thiab nws yog qhov me me thiab nyob hauv ib cheeb tsam me me, uas tsim nyog rau kev txhim kho cov khoom siv hluav taws xob ntau hauv qhov chaw txwv.
Daim ntawv thov teb
Hlau-clad switchgearyog dav siv nyob rau hauv lub sij hawm uas yuav tsum tau muaj zog mechanical zog thiab kev tiv thaiv kev ua tau zoo, xws li cov tsev lag luam, cov tsev lag luam thiab cov tsev siv hluav taws xob. GIS yog dav siv nyob rau hauv lub hwj chim kis tau tus mob thiab tis systems vim nws superior kev kawm thiab kev ntseeg siab, tshwj xeeb tshaj yog nyob rau hauv high-ceev railways, subways thiab rail transit systems. GIS ua tau zoo tshwj xeeb hauv cov haujlwm no, tsis yog tsuas yog nce cov khoom siv ceev tab sis kuj txo cov nqi khiav lag luam.
Kev tu thiab tu
Kev saib xyuas ntawm cov hlau-clad switchgear yog qhov yooj yim, feem ntau suav nrog kev tu thiab tu cov cuab yeej zoo li qub thiab kev tshuaj xyuas tsis tu ncua ntawm cov khoom siv hluav taws xob sab hauv. GIS yuav tsum muaj kev saib xyuas zoo dua, suav nrog kev tshuaj xyuas tsis tu ncua ntawm cov pa hluav taws xob tso pa tawm, kev sib tsoo ntawm cov hlau casing thiab kev tiv thaiv xob laim rau cov khoom siv hluav taws xob. Cov roj insulator ntawm GIS yog lub tsev cog khoom muaj zog, thiab nws cov dej xau yuav tsum tau tswj nruj kom tsis txhob muaj kuab paug ib puag ncig.
Xaus
Hlau-clad switchgear thiab roj-insulated switchgear txhua tus muaj lawv tus kheej qhov zoo, thiab kev xaiv ntawm cov cuab yeej twg nyob ntawm qhov tshwj xeeb daim ntawv thov scenario thiab xav tau. Nyob rau hauv cov xwm txheej uas yuav tsum tau muaj zog mechanical zog thiab kev tiv thaiv kev ua tau zoo, hlau-clad switchgear yog ib qho kev xaiv zoo dua; Nyob rau hauv cov xwm txheej uas muaj zog rwb thaiv tsev, me me hneev taw, tsis tshua muaj nqi khiav lag luam thiab kev ntseeg siab yuav tsum tau, GIS yog qhov zoo dua. Yog li ntawd, thaum xaiv switchgear, nws yuav tsum raug xaiv raws li ib puag ncig siv tshwj xeeb thiab kev ua haujlwm kom ntseeg tau tias cov cuab yeej tuaj yeem ua tau zoo tshaj plaws.
Hauv cov ntsiab lus,hlau-clad switchgearthiab gas-insulated switchgear muaj lawv tus kheej zoo, thiab nws yog tsis yooj yim sua kom generalize qhov twg yog zoo dua. Qhov tseem ceeb yog ua kom muaj kev tshawb fawb thiab tsim nyog xaiv raws li qhov xav tau tiag tiag kom ua tiav kev nyab xeeb, ua haujlwm zoo thiab ruaj khov ntawm lub zog hluav taws xob.
