Maintenance Ntawm Nqus Circuit Court Breaker

Nqus Circuit Court breaker yog dav siv nyob rau hauv kev lag luam tsim khoom thiab kev faib tawm tam sim no, cov khoom siv ntau yam xws li VS 1-12 lub tshuab nqus tsev vacuum breaker, tab sis vim nws qhov ntsuas hluav taws xob siab, siab tam sim no, ya hma liab muaj peev xwm muaj zog, ua rau ntau yam. ntawm cov teeb meem thiab kev phom sij zais, ib qho kev tuav tsis raug, nws yuav ua rau muaj kev sib tsoo ntau heev. Yog li ntawd, nws xav kom peb ntxiv dag zog rau kev tswj hwm hauv cov txheej txheem ntawm lub tshuab nqus tsev vacuum breaker xaiv, kev teeb tsa, kev ua haujlwm, kev kho dua tshiab thiab kev saib xyuas, saib xyuas thiab kuaj xyuas cov xwm txheej ntawm lub tshuab nqus tsev vacuum breaker hauv kev ua haujlwm, thiab daws cov teeb meem tshwm sim raws sijhawm thiab raug.
1, debugging thiab handover test nruj me ntsis zoo cov cuab yeej debugging thiab handover test, nyob rau hauv thiaj li yuav tiv thaiv cov kev hloov ntawm cov khoom nyob rau hauv kev thauj mus los thiab kev hloov kho mechanism tom qab qhov tshwm sim ntawm mismatch, tshwj xeeb tshaj yog tom qab kev khiav hauj lwm mechanism thiab lub tshuab nqus tsev breaker kev twb kev txuas. Cov kev ntsuas tseem ceeb yog: kaw bounce, qhib lub sij hawm, qhib qhov deb, shrinking stroke, kaw ceev thiab lub sij hawm, DC tsis kam, qhib thiab kaw lag luam voltage tus nqi, tawg rwb thaiv tsev theem, kis tau tus mob kev kuaj, thiab lwm yam, cov tsis yuav tsum tau raws li qhov yuav tsum tau. . Hauv peb qhov kev ua haujlwm niaj hnub niaj hnub, feem ntau pom cov teeb meem hauv qab no: Lub phaj nthuav dav ntawm qhov sib txuas zoo li qub hauv lub txee hluav taws xob hluav taws xob thiab cov thav duab ntawm tes Circuit Court breaker yog daig, uas ua rau muaj teeb meem hauv kev nkag mus rau hauv lub tsheb. Lub bounce thiab stroke ntawm Circuit Court breaker yog tsis tsim nyog. Lub insulator ntawm lub Circuit Court breaker lub cev yog tawg vim qhov kev ncua deb ntawm nws thiab khi pas nrig, thiab cov yam ntxwv ntawm lub kaw contactor tsis zoo. Peb tau daws tag nrho cov teeb meem no. Qhov kev debugging thiab xa mus kuaj ntawm lub tshuab nqus tsev Circuit Court breaker yuav tsum tau ua nruj me ntsis. Peb yuav tsum nrhiav kom tau raws sij hawm qhov kev puas tsuaj ntawm cov rwb thaiv tsev, cov txheej txheem tsis zoo, cov pa tawm hauv lub tshuab nqus tsev arc extinguishing chamber, thawm txawv txav, ceev thiab mob stroke thiab lwm yam tsis tsim nyog, thiab ua haujlwm zoo ua ntej lawv muab tso rau hauv kev ua haujlwm kom muaj kev nyab xeeb.
2. Kev ua haujlwm thiab kev saib xyuas, kev tshuaj xyuas tsis tu ncua
2, 1, kev ua haujlwm thiab kev tswj xyuas kev ua haujlwm, ua tib zoo saib xyuas seb puas muaj qhov txawv txav, xws li tom qab lub tshuab hluav taws xob raug txiav, seb puas muaj suab nrov txawv txav, thaum lub hwj huam mov, saib seb puas muaj qhov tawg, puas yog qhov tseeb. khoob arc extinguishing chamber. Tshaj tawm txhua qhov tsis txaus ntseeg tam sim ntawd thiab ua haujlwm tsuas yog tom qab kev saib xyuas tau lees paub.
2.2. Kev tshuaj xyuas tsis tu ncua ntawm lub tshuab nqus tsev Circuit Court breaker lub cev muaj xws li: lub tshuab nqus tsev arc extinguishing chamber cua to, lub cev rwb thaiv tsev tawg, unqualified overvoltage protector, unqualified DC kuj ntawm lub tshuab nqus tsev arc extinguishing chamber, rejection ntawm tshiab muab tso rau Circuit Court breaker, thiab lwm yam. , DC tsis kam thiab hloov qhov ntsuas hluav taws xob yog qhov tseem ceeb kom pom cov teeb meem saum toj no.
3. Lub xeev saib xyuas thiab kuaj xyuas lub tshuab nqus tsev Circuit Court breaker
Nqus arc extinguishing chamber yog qhov tseem ceeb ntawm lub tshuab nqus tsev vacuum breaker. Nws yog kev txhawb nqa thiab kaw los ntawm iav los yog ceramic. Nws muaj dynamic thiab dynamic hu thiab shielding npog, thiab lub tshuab nqus tsev degree yuav tsis qis dua 6.6x 10-2P a. Factory - ua tshiab lub tshuab nqus tsev quench chamber yuav tsum ncav cuag 7.5 x 10-4Pa. Thaum lub tshuab nqus tsev kawm ntawv txo qis, qhov kev ua haujlwm tawg tau qis dua. Yog li ntawd, lub tshuab nqus tsev arc extinguishing chamber tsis tuaj yeem raug khob lossis sib tsoo los ntawm ib qho kev quab yuam sab nraud.
3.1. Qhov loj tshaj plaws ntawm lub tshuab nqus tsev Circuit Court breaker yog qhov kev sib cuag tau kaw rau hauv lub plhaub insulating ntawm lub tshuab nqus tsev arc extinguishing raj. Nws yog tsim nrog cov cuab yeej siv niaj hnub raws li kev tswj hwm nruj thiab tuaj yeem ua kom lub neej ntev. Yuav tsum tau kuaj xyuas hauv cov xwm txheej hauv qab no, yog tias tsim nyog
Lub tshuab nqus tsev npuas yuav tsum tau hloov:
(I) Lub tshuab nqus tsev arc extinguishing chamber tau mus txog lub sij hawm on-off guaranteed los ntawm cov chaw tsim tshuaj paus (tus neeg kho tshuab lub neej 10, 000 zaug);
(2) Lub tshuab nqus tsev arc extinguishing chamber tau mus txog lub voj voog tshuaj xyuas (thaum tus naj npawb ntawm kev tawg thiab kaw mus txog 10, 000 zaug thiab luv Circuit Court tam sim no mus txog 100 zaug, qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob tua hluav taws yuav tsum yog nqa tawm, thiab lub tshuab nqus tsev extinguishing chamber yuav tsum tau hloov thaum nws mus txog 20, 000 zaug);
(3) Thaum pom qhov txawv txav. Kev soj ntsuam hauv paus: Lub neej ntawm lub tshuab nqus tsev Circuit Court breaker yog txiav txim los ntawm kev sib cuag thiab lub tshuab nqus tsev kawm ntawv:
(1) Kev ntsuas kev sib cuag. Kev tiv tauj overstroke ntawm lub tshuab nqus tsev vacuum yog kuaj los ntawm kev khij qhov sib txuas ntawm lub tshuab nqus tsev vacuum lossis ntsuas los ntawm vernier caliper. Yog tias qhov hnyav hnyav ntawm kev txav mus los thiab kev sib cuag zoo li qub tshaj li qhov teev tseg, nws qhia tau hais tias lub tshuab nqus tsev nqus tau tas sij hawm, thiab lub tshuab nqus tsev yuav tsum tau hloov.
(2) DC tsis kam ntawm lub tshuab nqus tsev npuas yog nyob rau hauv qhov kev teev tseg. Lub tshuab nqus tsev vacuum DC kuj tsis ntau dua 25 μΩ, lub tshuab nqus tsev vacuum breaker conductive Circuit Court tsis ntau dua 45μΩ
(3) Lub tshuab nqus tsev degree ntsuas.
① fais fab zaus voltage kuj txoj kev. Ua lub Circuit Court breaker nyob rau hauv lub xeev off-lub xeev, ntxiv voltage ntawm cov neeg nyob rau hauv lub nqus arc extinguishing chamber los txiav txim lub peev xwm los tiv thaiv 42kV, Imin fais fab zaus voltage xeem, lub nqus npuas yuav tsum tsis txhob yuav tas mus li tso tawm, nws yog suav tias yog ib txwm.
② Vacuum degree tester test. Tam sim no, txoj kev raug ntau dua yog txoj kev tswj kev sib nqus, uas yog tsim rau kev tshawb nrhiav lub tshuab nqus tsev tua hluav taws hauv cov chaw tsim khoom. Lub tshuab nqus tsev degree tsis ntau tshaj 5 * 10-4Pa,
③ Sparkmeter txoj kev. Nws tsuas yog tsim rau iav raj lub tshuab nqus tsev arc extinguishing chamber. Thaum nws siv, cia lub txim hluav taws xob txav mus rau ntawm qhov chaw ntawm lub arc extinguishing chamber, thiab muaj qhov sib txawv luminescence nyob rau hauv qhov kev txiav txim ntawm nws high-frequency hluav taws xob teb. Yog tias muaj lub teeb ntsuab ci nyob rau hauv lub raj, lub tshuab nqus tsev kawm ntawv siab tshaj 1.33 * 10-5; Yog tias lub teeb liab thiab xiav, cov yeeb nkab ua tsis tiav; Yog hais tias lub raj twb nyob rau hauv cov huab cua, nws yuav tsis emit lub teeb.
