Kev piav qhia ntawm Vacuum Circuit Breaker Application

Core Application Domains

Lub tshuab nqus tsev vacuum breakers, vim lawv qhov kev ua tau zoo heev, tau dhau los ua cov khoom siv hloov pauv tseem ceeb hauv qhov nruab nrab -voltage field (nrog rau qib voltage feem ntau yog li ntawm 3kV txog 40.5kV). Lawv cov xwm txheej tseem ceeb ntawm kev thov suav nrog:

1. Kev lag luam thiab kev tsim khoom

Cov chav faib khoom hauv cov chaw tsim khoom loj: xws li cov nroj tsuag tshuaj, steel mills, tsheb tsim cov chaw, cov ntaub ntawv chaw, thiab lwm yam. Cov chaw no muaj ntau heev thiab siab -cov khoom siv hluav taws xob, ua rau lawv yooj yim rau overload los yog luv luv Circuit Court.

2. Fais fab System

Substations: Qhov no yog thawj thiab feem ntau classic daim ntawv thov site rau lub tshuab nqus tsev vacuum breakers. Nyob rau hauv substations nrog voltage theem ntawm 35kV thiab hauv qab no, lawv yog siv raws li nkag thiab tawm kab switches, busbar khi keyboards, thiab transformer tiv thaiv keyboards, lub luag hauj lwm rau kev faib, dispatching, thiab kev tiv thaiv ntawm hluav taws xob lub zog.

3. Infrastructure thiab Commercial Buildings

Kev faib hluav taws xob rau cov tsev siab - nce siab: Lub hauv paus hluav taws xob faib hluav taws xob ntawm cov niaj hnub siab - nce chaw ua haujlwm, tsev kho mob, tshav dav hlau, thiab cov khw loj loj yuav tsum muaj cov cuab yeej tiv thaiv zoo.

4. Kev thauj mus los

Electrified railways: Siv nyob rau hauv traction substations ntawm railways, tswj cov khoom siv hluav taws xob rau hluav taws xob locomotives.

Vim li cas lawv tau siv dav hauv cov haujlwm no? - Kev soj ntsuam zoo

Piv nrog cov roj hluav taws xob hluav taws xob thaum ntxov, roj- tsim cov hluav taws xob hluav taws xob, thiab SF6 (sulfur hexafluoride) Circuit Court breakers, lub tshuab nqus tsev hluav taws xob muaj qhov zoo tshaj plaws:

Strong arc extinguishing peev xwm, ntev lifespan:

Lub tshuab nqus tsev yog ib qho zoo tagnrho insulator, thiab nws cov dielectric rov qab ceev ceev heev. Thaum qhov tam sim no rov qab mus rau xoom, cov hlau vapor tsim los ntawm arc tuaj yeem nrawm nrawm thiab nrawm, tso cai rau lub zog rwb thaiv tsev ntawm cov neeg sib cuag kom rov zoo sai thiab tsis yooj yim dua. Kev tiv thaiv hnav yog me me, thiab hluav taws xob lifespan ntev.

Me me, lub teeb yuag:

Vim lub siab rwb thaiv tsev lub zog ntawm lub tshuab nqus tsev, lub interrupter chamber yuav ua tau heev compact, yog li tag nrho cov ntim thiab qhov hnyav ntawm lub Circuit Court breaker yog npaum li cas me dua li cov roj Circuit Court breakers ntawm tib theem, yooj yim installation thiab sib dhos rau hauv lub thawv hloov, thiab txuag chaw.

Kev txiav txim sai, muaj peev xwm tawg loj:

Nws tuaj yeem txiav tawm qhov tsis raug tam sim no sai sai (feem ntau nyob rau hauv kaum tawm milliseconds), txo qhov cuam tshuam ntawm luv luv - cov tam sim no ntawm lub cev.

Haum rau kev ua haujlwm nquag:

Tshwj xeeb tshaj yog tsim nyog rau lub sijhawm uas yuav tsum tau muaj kev cuam tshuam ntau zaus, xws li arc furnaces, tswj lub cev muaj zog, thiab lwm yam.

Lub ntsiab lus ntawm Kev Ua Haujlwm (Core: Vacuum Arc Nqus Tsev)

1. Kev coj ua zoo li qub: Thaum lub Circuit Court breaker raug kaw, cov kev txav mus los thiab zoo li qub tuaj rau hauv kev sib cuag raws li qhov kev txiav txim ntawm cov neeg kho tshuab mechanism, thiab Circuit Court yog ua.

2. Tripping thiab Arc Generation: Thaum nws yog ib qho tsim nyog yuav tsum tau tawg lub voj voog (tshwj xeeb yog txiav tawm qhov txhaum tam sim no), lub tshuab ua haujlwm (xws li lub caij nplooj ntoos hlav lossis lub tshuab electromechanical) yuav nrawm nrawm ntawm kev sib cuag. Thaum lub sijhawm sib cais, vim muaj qhov hluav taws xob muaj zog thiab qhov kub thiab txias, cov khoom siv sib txuas yuav evaporate thiab tsim cov hlau vapor, uas ua rau lub arc hauv lub tshuab nqus tsev (lub npe hu ua arc arc).

3. Kev Tiv Thaiv Arc ntawm Zero Tam Sim No: Cov yam ntxwv ntawm lub tshuab nqus tsev arc yog qhov siab ntawm cov hlau vapor nyob rau hauv arc kem yog qhov tsawg heev, thiab cov khoom siv hluav taws xob yuav nrawm nrawm rau txhua qhov kev qhia. Thaum qhov hloov pauv tam sim no nce mus txog xoom, lub arc ib ntus extinguishes, thiab cov hlau vapor yuav condense sai heev thiab tso rau ntawm cov neeg thiab cov ntaub thaiv npog. Yog li, qhov sib txawv ntawm kev sib cuag sai sai rov qab mus rau lub tshuab nqus tsev siab, rov ua kom muaj zog rwb thaiv tsev siab, yog li tiv thaiv qhov re-ignition ntawm arc thiab ua tiav cov txheej txheem "so".

Cov ntsiab lus

Tam sim no, nyob rau hauv nruab nrab-voltage field, lub tshuab nqus tsev vacuum breakers tau hloov cov roj ntau thiab SF6 Circuit Court breakers. Nyob rau hauv qhov siab -voltage field, txawm hais tias SF6 tseem yog qhov tseem ceeb thev naus laus zis, ib puag ncig tus phooj ywg lwm cov pa roj (xws li "huab cua qhuav", fluorosulfonated acrylonitrile mixed gas, thiab lwm yam) thiab kev txhim kho ntawm lub tshuab nqus tsev vacuum breakers mus rau qib siab dua voltage (xws li 145 kV) yog qhov kev tshawb fawb tam sim no hotspots.

Lub tshuab nqus tsev vacuum breaker yog qhov hloov pauv ntse uas siv qhov zoo tshaj plaws arc - tua thiab rwb thaiv tsev ntawm lub tshuab nqus tsev. Nrog nws cov yam ntxwv zoo xws li kev nyab xeeb, kev nyab xeeb ib puag ncig, kev saib xyuas- kev ua haujlwm dawb, me me, thiab kev ua neej ntev, nws ruaj khov tuav txoj haujlwm tseem ceeb hauv nruab nrab -voltage fais fab faib network. Nws yog ib qho tseem ceeb ntawm "tus saib xyuas kev nyab xeeb" hauv cov tshuab hluav taws xob niaj hnub no, kev tsim khoom lag luam, thiab kev tsim kho hauv nroog, thiab yog cov khoom siv hluav taws xob tseem ceeb rau kev ua kom muaj kev ntseeg siab ntawm cov khoom siv hluav taws xob thiab cov khoom siv kev nyab xeeb.
