High-voltage switchgearKev tsis ua haujlwm feem ntau tshwm sim hauv rwb thaiv tsev, conductivity, thiab mechanics.
(i) Tsis muaj zog lossis tsis ua haujlwm.
Hom kev tsis ua haujlwm no yog qhov tsis ua haujlwm tseem ceeb ntawm high-voltage switchgear, thiab nws cov laj thawj tuaj yeem muab faib ua ob pawg. Ib qho yog tshwm sim los ntawm cov neeg kho tshuab tsis ua hauj lwm ntawm kev khiav hauj lwm mechanism thiab kis tau tus mob, uas yog manifested li mechanism jamming, Cheebtsam deformation, tshem tawm los yog puas, xoob hloov core, xoob ncej pin, tso tsis ua hauj lwm, thiab lwm yam yog tshwm sim los ntawm hluav taws xob tswj thiab pab. circuits, uas yog tus cwj pwm los ntawm kev sib txuas tsis zoo ntawm ob txoj hlua hluav taws xob, xoob xaim terminals, thiab cov xaim tsis raug.
(ii) Txhaum thiab kaw tsis ua haujlwm
Hom kev ua tsis tiav no yog tshwm sim los ntawm kev sib tsoo hluav taws xob. Rau cov roj hluav taws xob hluav taws xob qis, nws qhov kev ua haujlwm tseem ceeb yog roj txhaj tshuaj luv luv, arc extinguishing chamber hlawv, tsis muaj peev xwm txiav tawm, kaw lub sij hawm tawg, thiab lwm yam. Rau lub tshuab nqus tsev Circuit Court breakers, nws txhais tau hais tias lub arc extinguishing chamber thiab bellows xau, lub tshuab nqus tsev vacuum. degree raug txo qis, lub txhab nyiaj capacitor rov ua dua, thiab cov raj ceramic tawg.
(iii) Rwb thaiv tsev tsis ua haujlwm
Qib rwb thaiv tsev hais txog kev sib raug zoo ntawm kev tuav peb qhov hluav taws xob (suav nrog kev ua haujlwm voltage thiab ntau yam overvoltages), ntau yam kev txwv voltage, thiab lub zog rwb thaiv tsev. Siv zog ua kom cov khoom muaj kev nyab xeeb thiab kev lag luam kom ua tiav cov txiaj ntsig kev lag luam loj tshaj plaws. Lub ntsiab rwb thaiv tsev faults yog av flashover, internal rwb thaiv tsev, hauv av flashover, flashover, rwb thaiv tsev flashover, xob laim overvoltage flashover, ceramic bushing, capacitor bushing, flashover, tawg, tawg, boom flashover, CT flashover, tawg, tawg, porcelain lub raj mis tawg, thiab lwm yam. .
(IV) Tam sim no loading tsis ua hauj lwm
Lub ntsiab yog vim li cas rau tam sim no tsis ua hauj lwm nyob rau hauv lub 72 ~ 12KV voltage ntau yog vim tsis muaj kev sib cuag ntawm lub cais plug, ua rau tsis zoo kev sib cuag ntawm lub switchgear.
(V) Sab nraud quab yuam thiab lwm yam txhaum
Nws suav nrog cov khoom txawv teb chaws tsis paub, kev puas tsuaj ntuj tsim, cov tsiaj luv luv, thiab lwm yam tsis paub txog sab nraud thiab xwm txheej.
Txawm hais tias qhov kev tshuaj xyuas thiab kev tshuaj xyuas ua haujlwm tau ua tiav ua ntej kev yuav khoom thiab siv cov khoom siv hluav taws xob siab, qhov tseeb, cov khoom siv nrog cov teeb meem tsis zoo hauv lub cev yuav inevitably muab tso rau hauv kev siv. Tsis tas li ntawd, vim yog sab nraud quab yuam thiab tshuab kev laus, nws tseem nyuaj rau high-voltage switchgear kom muaj kev ruaj ntseg mus tas li. Raws li kev ntsuas kho, cov neeg siv yuav tsum ntxiv dag zog rau kev tshuaj xyuas ntawm high-voltage switchgear. Tsuav peb pom thiab pom qhov txawv txav hauv lub sijhawm, peb tuaj yeem zam kev raug xwm txheej.
(i) Kev tshawb nrhiav thiab kev siv cov tshuab tsis ua haujlwm
Ntau qhov kev txheeb xyuas qhia tau tias feem pua ntawm cov tshuab tsis ua haujlwm hauv switchgear yog qhov siab tshaj plaws. Qhov no yog vim muaj ntau yam cuam tshuam nrog kev ua haujlwm ntawm cov tshuab, nrog rau cov kev sib txuas thiab kaw cov kab hluav taws xob. Tsis tas li ntawd, kev ua haujlwm ntawm qhov hloov pauv kuj tsis zoo. Qee lub sij hawm nws tsis khiav mus ntev, tab sis qee zaus nws yuav tsum khiav tsis tu ncua. Tsis tas li ntawd, nws tseem cuam tshuam los ntawm ib puag ncig kev hloov pauv txhua xyoo. Yog li ntawd, mechanical failures, tshwj xeeb tshaj yog kev txav tsis tau, feem ntau yuav muaj.
Txhawm rau kom ntseeg tau qhov kev ntseeg tau ntawm kev ua haujlwm ntawm lub switchgear, lub switchgear yuav tsum tau kuaj thiab xyuas. Piv txwv li, ua ntej lub tshuab nqus tsev vacuum breaker yog tsim, lub tshuab feem ntau ua haujlwm ntau pua zaus ntawm tus qauv ua haujlwm voltage. Yog tias qhov ua tsis tiav, nws yuav ua tiav ua ntej tawm hauv lub hoobkas. Qhov thib ob, txhua qhov chaw ntawm lub switchgear, tshwj xeeb tshaj yog nyob rau hauv qhov kev txiav txim, nrog rau cov fastening screws, springs, thiab rub rods nyob rau hauv tag nrho cov qhov chaw, muaj txaus lub zog thiab txhim khu kev qha qauv los tiv thaiv cov kev xeem ntawm lub sij hawm ntev kev ua haujlwm.
Txhawm rau kom ntseeg tau tias kev sib txuas hluav taws xob zoo, kev ua haujlwm ntawm cov khoom siv xws li kaw, kaw cov coils, thiab cov pab cuam hloov pauv yuav tsum tau lav. Txij li thaum nws yog ib lub voj voog, cov keyboards, fuses, thiab kev sib txuas hauv Circuit Court yuav tsum nyob hauv qhov zoo, thiab DC lub zog ua haujlwm yuav tsum nyob hauv ib txwm muaj. Yog hais tias DC Circuit Court tsis zoo insulated, ib-point grounding los yog multi-point grounding tej zaum yuav ua rau lub hloov mus ua hauj lwm tsis raug. Yog hais tias lub DC Circuit Court tsis zoo los yog lub hwj chim mov tsis zoo, kev tsis lees yuav tshwm sim.
Txawm hais tias nws yog cov chaw tsim khoom lossis chaw ua haujlwm, kev ua haujlwm yuav tsum ua kom zoo. Txhawm rau txo qhov tsis ua haujlwm ntawm lub tshuab.
(ii) Rwb thaiv tsev ntsuas ntsuas
Nyob rau hauv txoj cai, qhov siab dua qhov voltage, qhov ntau xim yog them rau kev xaiv ntawm rwb thaiv tsev theem. Rau nruab nrab voltage theem, nws yog feem ntau vam tias cov rwb thaiv tsev theem yuav siab dua me ntsis thiab muaj kev nyab xeeb los ntawm kev nce nqi.
Raws li ib tug kws manufacturers ntawmswitchgear, peb paub zoo txog nws qhov tseem ceeb thiab tau cog lus los muab cov neeg siv khoom zoo thiab cov kev pabcuam zoo. Yog xav paub ntxiv, thov koj xav tiv tauj peb.
