Lub ZN73-12 series sab hauv tsev peb-theem AC high-voltage vacuum circuit breaker los ntawm People Electric yog lub cuab yeej tiv thaiv kev hloov pauv tseem ceeb uas tau hloov kho rau 12kV, 50Hz peb-theem AC fais fab systems. Tsim los rau kev lag luam thiab kev tsuas, cov chaw tsim hluav taws xob, cov chaw hloov pauv thiab lwm yam xwm txheej, nws ua haujlwm ua lub cuab yeej tseem ceeb hauv cov kab ke faib hluav taws xob hauv kev lag luam, nrog rau cov txiaj ntsig tseem ceeb thiab kev hloov pauv tau pom hauv plaub yam:
1.Kev Hloov Kho Qhov Xwm Txheej Tseeb & Kev Tso Chaw Tseem Ceeb: Nws ua rau muaj kev hloov pauv ntawm ntau yam khoom thauj thiab kev tiv thaiv & kev tswj hwm ntawm cov chaw hluav taws xob, tshwj xeeb tshaj yog haum rau cov xwm txheej fais fab kev lag luam uas xav taukev ua haujlwm ntau zaus, muab kev tiv thaiv hluav taws xob thiab kev tswj hwm rau cov xwm txheej faib hluav taws xob siab ntawm ntau qhov sib txawv.
2.Kev Ua Haujlwm Zoo Tshaj Plaws ntawm Arc Extinguishing & Kev Tsim Qauv: Siv lub tshuab nqus tsev ua lub tshuab tua hluav taws xob thiab rwb thaiv tsev thiab cov khoom siv tooj liab-chromium sib cuag, nws muaj qhov tsis tshua muaj hluav taws xob hnav, tiv taus hluav taws xob siab thiab rov qab tau sai sai ntawm lub zog rwb thaiv tsev tom qab-arc kom txiav cov hluav taws xob txhaum sai thiab ruaj khov. Nws siv cov qauv sib xyaw ua ke nrog lub tshuab ua haujlwm thiab chav tua hluav taws xob arc teeb tsa pem hauv ntej thiab tom qab, thiab lub voj voog hluav taws xob peb-theem pem teb. Lub chav tua hluav taws xob arc tau teeb tsa hauv lub tog raj kheej nrog epoxy resin ntawm APG thev naus laus zis, xa cov khoom tiv taus creepage muaj zog thiab cov hmoov av tsawg. Lub caij no, nws txo cov kev sib txuas kis nruab nrab kom txo qis kev siv hluav taws xob thiab suab nrov nrog kev ua haujlwm txhim khu kev qha.
3.Kev Teeb tsa Qauv Yooj Yim & Kev Tiv Thaiv Tag NrhoMuaj nyob rau hauvhom ruaj khovthiabhom kos tawm, nws tuaj yeem ntsia tau rau hauv cov txee hloov kho thiab rub tawm tau raws li ntau yam kev teeb tsa thiab kev ua haujlwm & kev saib xyuas. Nruab nrog cov khoom siv tiv thaiv hluav taws xob tag nrho suav nrog kev tiv thaiv kev mus ncig relay, over-current tripping electromagnet thiab lub zog cia micro-switch, nws txhim kho kev nyab xeeb ntawm kev ua haujlwm. Nws ua haujlwm ruaj khov ntawm -10 ℃ txog + 40 ℃, tiv taus av qeeg txog li 8 qhov loj, thiab ua haujlwm tau zoo hauv ib puag ncig tsis muaj cov pa roj corrosive / flammable lossis kev co hnyav. Cov kev pabcuam tshwj xeeb tau muab rau cov xwm txheej ua haujlwm tshwj xeeb.
4.Kev Xaiv Qauv Ntau Yam & Kev Ua Haujlwm Tsawg & Tus Nqi Txij Nkawm: Qhov ntsuas tam sim no yog txij li 630A txog 3150A, thiab qhov ntsuas luv luv tawg tam sim no npog 20kA txog 40kA, tso cai rau kev xaiv yooj yim raws li qhov tam sim no ntawm qhov chaw. Nrog lub neej ua haujlwm ntev, kev saib xyuas yooj yim, tsis muaj kuab paug thiab tsis muaj kev pheej hmoo tawg, nws txo cov nqi ua haujlwm thiab kev saib xyuas rau cov neeg siv khoom lag luam.
Cov Khoom Tseem Ceeb Tseem Ceeb
1.Cov Khoom SivLub tshuab hluav taws xob nqus tsev peb-theem AC high-voltage sab hauv tsev tau hloov kho rau 12kV / 50Hz fais fab systems, ua raws li cov qauv hauv tebchaws. Lub tshuab nqus tsev arc-extinguishing nruab nrab ua kom muaj kev ua haujlwm zoo tshaj plaws ntawm kev tua arc thiab kev rwb thaiv tsev.
2.Cov txiaj ntsig tseem ceebCov khoom siv tooj liab-chromium uas tsis hnyav thiab siv tau ntev; cov qauv sib xyaw ua ke siv hluav taws xob tsawg, tiv taus creepage thiab tiv taus kuab paug; lub neej ua haujlwm kho tshuab 10,000 zaug, qhib/kaw saiteb thiab muaj peev xwm tawg qhov txhaum loj heev; cov khoom tiv thaiv tiav rau kev nyab xeeb ua haujlwm siab.
3.Cov Xwm Txheej ntawm Daim Ntawv ThovKev tiv thaiv thiab kev tswj hwm cov chaw hluav taws xob hauv cov chaw lag luam thiab cov chaw tsuas, cov chaw tsim hluav taws xob, cov chaw hloov pauv,tshwj xeeb tshaj yog tsim rau kev hloov pauv nrog kev ua haujlwm ntau zaus.
4.Kev Tsim Kho & Kev Kho Kom Haum: Cov qauv ruaj khov thiab kos tawm uas hloov tau rau ntau lub txee hloov pauv; kev tsim khoom tshwj xeeb muaj rau cov xwm txheej ua haujlwm tshwj xeeb nrog kev hloov pauv ib puag ncig zoo.
