Circuit Court breaker yog ib qho khoom siv hluav taws xob hauv lub zog hluav taws xob, uas tuaj yeem txiav tawm thaum txoj kab lossis lub chaw nres tsheb luv luv lossis dhau los tiv thaiv cov khoom siv hluav taws xob thiab kev nyab xeeb ntawm tus kheej.
High voltage Circuit Court breakeryog tsuas yog tsim los ntawm arc extinguishing system, cuam tshuam qhov system, tswj cov cuab yeej thiab xyuas cov khoom.
Yog tias qhov hloov pauv tsis tuaj yeem raug txiav tawm hauv lub sijhawm, cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob yuav txiav tawm qhov yuam kev tuaj yeem tiv thaiv tus kheej kev nyab xeeb thiab khoom siv kev nyab xeeb.

I, Arc extinguishing system
Lub arc extinguishing system ntawm high voltage Circuit Court breaker muaj xws li arc generating ntaus ntawv, arc extinguishing ntaus ntawv thiab arc extinguishing chamber.
Hauv qhov hluav taws xob tsis tshua muaj hluav taws xob, feem ntau yog siv cov cua cuam tshuam los tua cov arc, vim hais tias nyob rau hauv cov huab cua cuam tshuam tsis muaj hluav taws xob tam sim no, yog li tsis tuaj yeem muaj arc los tsim.
Nyob rau hauv high voltage system, nqus arc extinguishing feem ntau yog siv, siv cov thermal nyhuv thiab electromagnetic quab yuam ntawm tam sim no nyob rau hauv lub tshuab nqus tsev arc extinguishing chamber.
Nyob rau hauv HVDC circuits, arc extinguishing feem ntau ua los ntawm mechanical extrusion vim yog DC tam sim no loj thiab yooj yim tshwm sim ntawm arc tawg.
Vim tias qhov ntim loj ntawm high voltage Circuit Court breaker, cua arc extinguishing chamber feem ntau yog siv.
II, Disconnection system
Lub breaker ntawm high voltage Circuit Court breaker feem ntau suav nrog electromagnet, electromagnetic kauj, thiab lwm yam.
Lub luag haujlwm ntawm lub tshuab hluav taws xob yog tsim cov hlau nplaum uas nias lub arc tawm tsam tus quab.
Lub luag haujlwm ntawm electromagnetic coil yog xa cov teeb liab mem tes thaum lub qhov hloov pauv tau qhib lossis tawm mus rau tus maub los, thiab tus maub los ua kom tiav qhov kev txiav tawm los ntawm kev tswj cov electromagnetic kauj kom tig los yog tawm.
Lub electromagnetic kauj kuj ua raws li electromagnetic cais.
Ib tug quab yog mounted ntawm lub Circuit Court breaker, uas ua rau lub arc voltage los tsim ib tug sib nqus teb ntawm tus quab, uas yog muab los ntawm ib tug khub ntawm synchronously rotating armatures, yog li tiv thaiv lub arc los ntawm nqa tawm lub Circuit Court los ntawm tus quab thiab ua rau ib tug quab yuam. xwm txheej.
III, Tswj cov cuab yeej
Circuit Court breakers feem ntau txais cov cuab yeej tswj tshwj xeeb, xws li microcomputer Circuit Court breakers (microcomputer tiv thaiv cov cuab yeej), nrog rau kev tswj thiab kev tiv thaiv kev ua haujlwm.
Lub luag haujlwm ntawm microcomputer tiv thaiv ntaus ntawv yog tsim kom muaj hluav taws xob lossis lub teeb liab tam sim no hauv Circuit Court thaum muaj kev txhaum, ces hloov nws mus rau hauv hluav taws xob teeb liab los yog mem tes teeb liab los ntawm amplifying circuit, thiab paub lub Circuit Court breaker ua hauj lwm muaj nuj nqi los ntawm relay los yog lwm yam kev tswj ( xws li reactor, isolator, thiab lwm yam).
Tsis tas li ntawd, muaj qee qhov kev hloov kho tshuab siv rau kev tswj tsis siv neeg hloov pauv, xws li SCR, SCR rectifier diodes, thiab lwm yam.
Txhawm rau txhim kho kev ntseeg tau thiab kev nyab xeeb, cov cuab yeej tiv thaiv microcomputer feem ntau siv cov khoom siv analog tso tawm los muab kev tiv thaiv ntau dua, xws li analog input / output (AFD), voltage / tam sim no ua ke (AVR) lossis tam sim no transformer voltage sampling.
IV, Saib xyuas cov khoom
Lub Circuit Court breaker yog nruab nrog cov txheej txheem ntawm kev saib xyuas tsis siv neeg, uas yog siv los txheeb xyuas qhov txawv txav hauv cov txheej txheem ntawm Circuit Court breaker.
Common high-voltage circuit breakers yog SF6, SF7, lub tshuab nqus tsev thiab lwm yam, raws li ntau hom yuav muab faib ua rated voltage 1000V, 1100V thiab 2000V.
Nrog rau kev txhim kho kev tshawb fawb thiab thev naus laus zis, HV Circuit Court breakers tau hloov kho tas li.Tam sim no, SF6 Circuit Court breaker thiab SF7 Circuit Court breaker yog dav siv nyob rau hauv peb lub teb chaws.
V 、 Kev teeb tsa thiab kev ceev faj rau cov hluav taws xob hluav taws xob hluav taws xob siab
Thaum txhim kho lub high voltage Circuit Court breaker, yuav tsum tau them nyiaj mloog mus rau qhov siab ntawm installation txoj hauj lwm thiab qhov deb;Cov kab txuas txuas yuav tsum raug xaiv rau ntawm Circuit Court breaker raws li qib voltage thiab luv Circuit Court tam sim no theem.
Txhawm rau kom tsis txhob muaj teeb meem xws li thermal effect thiab electromagnetic cuam tshuam thaum luv luv Circuit Court tam sim no tshwm sim, nws yuav tsum tau muab sau tseg tias lub installation txoj hauj lwm ntawm lub Circuit Court breaker yuav tsum nyob deb ntawm lub load center li sai tau;Thaum lub sij hawm installation, nws yuav tsum tau xyuas kom meej tias lub high voltage Circuit Court breaker yuav yooj yim them los ntawm lub hwj chim faib khoom, thiab kev khiav hauj lwm mechanism ntawm lub Circuit Court breaker yuav tsum muaj txaus qhov chaw rau kev txav mus los;thiab txoj hauj lwm ntawm kev khiav hauj lwm mechanism ntawm lub Circuit Court breaker yuav tsum yooj yim rau cais lub zog ua hauj lwm los ntawm kev ua hauj lwm fais fab mov.
