High-voltage switchgear yog dav siv nyob rau hauvkev faib hluav taws xobtshuab txais thiab faib hluav taws xob hluav taws xob. Lub txee hloov pauv muaj lub luag haujlwm ntawm suppressing internal faults. "Internal faults" hais txog qhov ua txhaum los ntawm arc luv circuits hauv lub txee hloov. Thaum muaj teeb meem sab hauv tshwm sim, nws yuav tsum txwv lub arc txhaum rau lub compartment. Nws kuj tseem siv tau los tiv thaiv qhov txhaum thaum cov khoom siv hluav taws xob lossis hluav taws xob tsis ua haujlwm. Cov khoom raug tshem tawm sai sai ntawm daim phiaj hluav taws xob kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm qhov tsis muaj qhov tsis raug ntawm daim phiaj hluav taws xob thiab kev nyab xeeb ntawm cov khoom siv thiab kev ua haujlwm thiab cov neeg ua haujlwm tu. Yog li ntawd, high-voltage switchgear yog ib qho khoom siv hluav taws xob tseem ceeb heev, thiab nws txoj haujlwm ruaj ntseg thiab txhim khu kev qha yog qhov tseem ceeb rau lub zog hluav taws xob.
Tam sim no, substations feem ntau siv KYN hom hloov khoom. Tam sim no peb yuav coj 10kV hloov txee qauv KYN28A-12 hloov txee ua piv txwv los piav qhia tag nrho cov qauv ntawm lub txee hloov.
Kev txheeb xyuas tus qauv
KYN28A-12 hloov txee yog tsim los ntawm lub txee lub cev thiab lub hauv paus rub-tawm handcart. Lub txee txais yuav cov qauv sib dhos, txuas nrog rivet ceev thiab lub zog muaj zog bolts, thiab tau muab faib ua plaub qhov sib cais los ntawm cov khoom siv hlau: Chav tsev busbar, B Circuit Court breaker chav, C cable chav thiab D relay chav, sab saum toj ntawm qhov hloov txee yog txawm peem rau nrog lub siab nyem li saum toj no lub Circuit Court breaker chav tsev, busbar chav tsev thiab chav cable.
1. Chav tsev tsheb npav
Lub busbar tseem ceeb yog ib chav tsev spliced thiab txuas los ntawm ib leeg nyob rau hauv lub compartment. Lub busbar tseem ceeb tau txais kev txhawb nqa los ntawm cov insulators, thiab cov ceg busbars txuas nrog lub hauv paus zoo li qub thiab lub ntsiab busbar los ntawm bolts.
Lub ntsiab busbar hla ntawm cov khoom nyob ib sab yog insulated los ntawm lub txee lub cev nrog lub tes tsho insulating. Yog tias muaj teeb meem sab hauv arc tshwm sim, nws tuaj yeem txwv qhov kev sib tsoo ntawm kev sib kis mus rau cov khoom nyob ib sab. Nws tuaj yeem txo qhov kev huam yuaj rau qhov chaw no thiab tib lub sijhawm txhawb nqa lub busbar.
2. Circuit Court breaker chav
Cov lus qhia tshwj xeeb tau muab tso rau hauv chav ntsuas hluav taws xob hluav taws xob, thiab lub tshuab hluav taws xob hluav taws xob hluav taws xob xaub thiab ua haujlwm sab hauv, tso cai rau lub laub txav ntawm qhov chaw ua haujlwm thiab qhov chaw sim. Cov ntaub thaiv kev tiv thaiv zoo li qub (valve) ntsia rau ntawm phab ntsa tom qab ntawm chav nqa nqa nqa tau kaw thaum lub laub txav ntawm qhov chaw ua haujlwm mus rau qhov chaw sim, thiab qhib tau txais thaum lub tsheb thauj khoom txav mus rau qhov sib txawv. Xyuas kom cov neeg ua haujlwm tsis txhob kov cov khoom nyob.
3. Chav Cable
Lub cable davhlau ya nyob twg kev twb kev txuas chav tsev muaj ib tug loj qhov chaw, uas yog yooj yim tsis tsuas yog rau lub installation ntawm thawj cables, tab sis kuj rau lub installation, hloov thiab txij nkawm ntawm cov thawj Cheebtsam xws li tam sim no transformers, grounding keyboards, ntes, thiab nyob cov lus qhia.
4. Relay ntsuas chav
Relay tiv thaiv Cheebtsam, cov twj paj nruag, cov ntsuas nyob, qhov taw qhia teeb, hloov hluav taws xob theem nrab thiab lwm yam khoom siv thib ob (cov ntawv tiv thaiv siab, cov tes tuav haujlwm) tau teeb tsa hauv chav ntsuas relay.
5. Lub siab nyem channel (ua tib zoo saib rau lub ntsiab transformer txee thiab lwm yam khoom nrog txuas hniav)
Thaum lub sijhawm ua haujlwm ntawm lub txee hloov, vim muaj ntau yam laj thawj, xws li kev laus ntawm cov rwb thaiv tsev sab hauv, qhov ua txhaum ntawm lub txee hloov pauv yog luv luv. Nyob rau hauv luv luv-circuit tam sim no ntawm kaum tawm txhiab tus amperes, gases nrog kub thiab siab siab yuav generated instantly. Yog tias cov pa roj no tsis tuaj yeem muaj nyob rau hauv lub txee me me hauv lub sijhawm luv luv, Kev tso tawm zoo nyob rau hauv qee lub sijhawm yuav ua rau lub txee hloov pauv, ua rau muaj kev puas tsuaj rau cov txee uas nyob ib sab, nthuav dav qhov txhaum, thiab tej zaum yuav ua rau raug mob, yog li muaj kev kub ntxhov. nyem channel yog tsim.
