Ntawm tag nrho cov tsis ua hauj lwm ntawm lub tshuab nqus tsev Circuit Court breaker (VCB), qhov ua txhaum loj tshaj plaws thiab txaus ntshai yog qhov txo qis hauv lub tshuab nqus tsev.nqus interrupter, uas ua rau lub tshuab nqus tsev poob. Nws muaj kev pheej hmoo siab dua li cov txheej txheem jamming, tiv tauj overheating, caij nplooj ntoos hlav qaug zog, theem nrab Circuit Court faults thiab lwm yam teeb meem. Raws li cov ntsiab lus tseem ceeb ntawm VCB, lub tshuab nqus tsev vacuum tso siab rau nws qhov chaw nruab nrab ntawm lub tshuab nqus tsev kom tua hluav taws xob arcs thiab muab kev sib cais ntawm rwb thaiv tsev. Qhov kev ua txhaum no tau zais ntau heev thiab tsis tuaj yeem kwv yees ua ntej los ntawm kev tshuaj xyuas qhov muag lossis niaj hnub saib xyuas kev soj ntsuam. Kab lus no yog ib qho kev tshuaj xyuas tag nrho ntawm qhov kev phom sij no los ntawm tsib qhov loj: qhov tshwm sim txhaum cai, ua rau kev tsom xam, kev phom sij txhaum cai, kev lis kev cai thiab kev tiv thaiv.
1. txhaumPdab tsi tshwm sim
Tam sim no cuam tshuam thiab arc extinction tshwm sim hauv lub tshuab nqus tsev vacuum ntawm VCB. Txij li thaum VCB tsis tau nruab nrog cov cuab yeej tsim los rau kev soj ntsuam zoo lossis ntau lub tshuab nqus tsev, lub tshuab nqus tsev degradation yog categorized raws li qhov tsis raug latent, uas yog qhov txaus ntshai tshaj qhov ua txhaum.
2. Ua rau Analysis
Cov laj thawj tseem ceeb ntawm kev txo lub tshuab nqus tsev yog:
Kev puas tsuaj ntawm cov khoom siv lossis cov txheej txheem tsim khoom ntawm lub tshuab nqus tsev vacuum, uas ua rau cov ntsiab lus micro-tawg ntawm lub tshuab nqus tsev nws tus kheej;
(2) Cov khoom siv tsis zoo lossis kev tsim cov hauv paus hauv lub tshuab nqus tsev vacuum, uas tsim cov ntsiab lus xau tom qab rov ua haujlwm;
(3) Rau split-type nqus Circuit Court breaker (xws li, VCB haum nrog electromagnetic kev khiav hauj lwm mechanisms), qhov ntev kev khiav hauj lwm txuas pas nrig adversely cuam tshuam lub breaker lub synchronism, hu bounce thiab over-travel yam ntxwv thaum lub sij hawm ua hauj lwm, accelerating tus nqi ntawm nqus℃txo.
3. Fasult Hazards
Qhov kev txo qis hauv Nqus theem cuam tshuam rau VCB lub peev xwm cuam tshuam overcurrent thiab ua rau nws lub neej ua haujlwm luv luv. Hauv qhov xwm txheej hnyav, nws tuaj yeem ua rau tawg tawg.
4. Txoj kev tuav
(1) Thaum lub sij hawm teem fais fab-tawg tu ntawm Circuit Court breakers, lub tshuab nqus tsev vacuum tester yuav tsum tau siv los ua qhov zoo ntawm lub tshuab nqus tsev ntsuas qhov ntsuas ntawm lub tshuab nqus tsev qhov muag kom ntseeg tau tias nws tswj tau lub tshuab nqus tsev txaus;
(2) Thaum qhov txo qis ntawm lub tshuab nqus tsev kawm ntawv tau lees paub, lub tshuab nqus tsev yuav tsum tau hloov, ua raws li cov yam ntxwv ntawm kev kuaj mob stroke, synchronism thiab kev sib cuag bounce.
5. Kev tiv thaiv
(1) Xaiv cov khoom lag luam VCB paub tab muab los ntawm cov tuam txhab muaj npe nrov;
(2) Xaiv lub tshuab nqus tsev vacuum nrog lub cev tseem ceeb thiab kev ua haujlwm;
(3) Thaum lub sij hawm niaj hnub tshuaj xyuas, cov neeg ua hauj lwm yuav tsum tau xyuas seb puas muaj cov pa paug tawm ntawm sab nrauv ntawm lub qhov hluav taws xob lub tshuab nqus tsev. Yog tias pom qhov paug tawm, qhov ntsuas ntsuas ntsuas ntsuas qhov ntsuas lub tshuab nqus tsev feem ntau yuav pom tias tsis txaus siab, thiab lub tshuab nqus tsev yuav tsum tau hloov tam sim tom qab de-energizing Circuit Court;
(4) Cov neeg ua haujlwm tu yuav tsum ua cov yam ntxwv rau kev sib txuas lus, kev sib cuag bounce, mob stroke thiab dhau mus ncig thaum lub hwj chim-tawg tu kom lub Circuit Court breaker nyob rau hauv lub suab khiav hauj lwm zoo.
Xaus
Lub hauv paus kev ua tau zoo ntawm lub tshuab nqus tsev Circuit Court breaker hinges ntawm lub tshuab nqus tsev tsim nyog hauv nws qhov cuam tshuam. Lub tshuab nqus tsev tsis ua haujlwm txhais tau hais tias qhov poob ntawm cov peev txheej tseem ceeb rau arc extinction thiab kev tiv thaiv luv luv. Rau switchgear manufacturers, EPC cov neeg cog lus thiab chaw nres tsheb fais fab kev khiav hauj lwm & tu pab pawg, nrog rau lub tshuab nqus tsev interrupter integrity soj ntsuam nyob rau hauv tsis tu ncua tu yog qhov tseem ceeb tshaj plaws los xyuas kom meej lub sij hawm ntev kev nyab xeeb thiab txhim khu kev qha kev khiav hauj lwm ntawm lub tshuab nqus tsev Circuit Court breaker.
