Ua kom muaj kev nyab xeeb ntawm lub tshuab ua haujlwm: Kev kaw ntau zaus thiab qhib kev ua haujlwm tuaj yeem cuam tshuam rau lub tshuab hluav taws xob ua haujlwm ntawm lub tshuab hluav taws xob, ua rau txhua yam hnav lossis puas tsuaj.
III. Hom Anti-trip Circuits
Kev tiv thaiv - ncig mus ncig Circuit Court feem ntau muab faib ua ob pawg: hluav taws xob thiab tshuab. Niaj hnub nimno lub tshuab nqus tsev vacuum breakers (tshwj xeeb tshaj yog nyob rau hauv nruab nrab thiab high voltage range) feem ntau siv hluav taws xob tiv thaiv -tripping, los yog ib tug ua ke ntawm hluav taws xob thiab txhua yam kev daws teeb meem.
Hluav taws xob tiv thaiv-tripping
Hluav taws xob tiv thaiv-tripping yog siv los ntawm relays thiab kev sib cuag logic thiab yog txoj kev siv ntau tshaj thiab txhim khu kev qha. Muaj ob txoj hauv kev xaim tseem ceeb:
a) Series Anti-tripping (Tam sim no pib, Voltage tuav)
Qhov no tam sim no yog qhov tseem ceeb tshaj plaws thiab siv dav los tiv thaiv -tripping tov.
Core Components:
Anti-tripping Relay (TBJ): Ib qho dual -coil relay nrog lub kauj pib tam sim no thiab lub zog tuav lub kauj, lossis ib qho -coil relay nrog latching hu.
TBJ's Nquag Qhib Kev Sib cuag (TBJ-1): Txuas qhov voltage coil latching circuit.
TBJ's Ncua Sijhawm Kaw (TBJ-2): Txuas nrog cov kab kaw, nws cuam tshuam cov lus txib kaw.
Txoj Cai Kev Ua Haujlwm:
Kaw: Thaum kaw cov lus txib, kaw cov dej ntws tam sim no, ib txoj hauv kev kaw lub Circuit Court breaker thiab lwm qhov ntws los ntawm cov kauj tam sim no ntawm kev tiv thaiv -tripping relay TBJ, ua rau nws mus.
Pib thiab tuav: Tom qab TBJ mus ncig, nws Nquag Qhib Hu rau TBJ-1 ib ntus kaw, txuas TBJ voltage coil circuit thiab tuav nws.
Kaw: Ib txhij, nws Nquag Kaw Hu TBJ-2 ib ntus qhib. Thaum lub sijhawm no, txawm hais tias qhov kev kaw kaw txuas ntxiv mus, lub kaw lus kaw tau raug txiav tawm los ntawm TBJ-2, tiv thaiv kev kaw ntxiv.
Rov pib dua: Thaum cov lus txib kaw thaum kawg ploj mus, TBJ voltage coil poob lub zog, relay rov pib dua, thiab ib txwm kaw kev sib cuag TBJ-2 rov qab, rov qab kaw lub voj voog thiab npaj rau qhov kev sim kaw tom ntej.
Qhov zoo:
Kev ntseeg siab thiab txhim khu kev qha los tiv thaiv -tripping nyhuv.
Zoo tiv thaiv tripping tshwm sim los ntawm kev kaw cov neeg sib cuag.
Qhov no yog tus qauv tsim thiab pom zoo kev daws teeb meem hauv kev lag luam tiv thaiv relay.
Qhov tsis zoo:
Kev xaim yog qhov nyuaj me ntsis, yuav tsum muaj dual -coil relay lossis ib qho ntxiv rau tus kheej- tuav lub voj voog.
b) Parallel anti-tripping (voltage-pib, voltage- tuav)
Txoj kev no yog ib txwm siv ntau dua thiab tam sim no tsis tshua siv hauv cov haujlwm tshiab.
Core Components:
Anti-tripping relay (TBJ): Tus qauv voltage- hom relay
TBJ feem ntau kaw cov neeg sib cuag: Txuas hauv koob hauv lub kaw lus kaw.
Lub Circuit Court breaker feem ntau qhib cov neeg sib cuag.
Txoj Cai Kev Ua Haujlwm:
Kaw: Tshaj tawm cov lus txib kaw, thiab lub Circuit Court breaker kaw. Pib: Tom qab lub Circuit Court breaker raug kaw, nws ib txwm qhib cov neeg pab cuam kaw. Thaum lub sijhawm no, yog tias qhov kaw lus tseem nyob, qhov hluav taws xob tau siv rau TBJ coil los ntawm lub kaw lus kaw, ua rau nws ua haujlwm.
Severing Kaw: Tom qab TBJ actuates, nws ib txwm kaw cov neeg sib txuas, txuas nrog rau hauv lub kaw lus kaw, qhib, kaw lub kaw lus kaw thiab tiv thaiv kev kaw ntxiv.
Rov pib dua: Tom qab kaw cov lus txib ploj mus, TBJ rov pib dua thaum lub zog tsis ua haujlwm.
Qhov tsis zoo: Yog hais tias lub Circuit Court breaker cov neeg pab cuam raug kho tsis raug lossis tsis teb, kev tiv thaiv -tripping yuav ua tsis tau.
Nws tsis tuaj yeem daws qhov teeb meem zoo uas qhov kev sib cuag kaw tam sim no.
Nws tsis tshua muaj kev ntseeg siab dua li cov series -hom Circuit Court breaker.
Mechanical Anti-trip
Cov neeg kho tshuab tiv thaiv-tripping muaj nuj nqi yog nyob ntawm tus qauv tsim ntawm Circuit Court breaker txoj haujlwm mechanism.
Txoj Cai Kev Ua Haujlwm: Siv lub caij nplooj ntoo hlav ua haujlwm ua piv txwv. Thaum lub mechanism nyob rau hauv txoj hauj lwm kaw, lub kaw lub caij nplooj ntoos hlav yog tag nrho them. Yog tias qhov kev kaw lus kaw tau txais ntawm qhov no, txij li lub tshuab yog twb nyob rau hauv txoj haujlwm kaw lawm, ib qho kev kaw lus hauv lub tshuab kaw lus tiv thaiv kev kaw ntxiv, yog li tiv thaiv kev sib tsoo. Cov lus txib kaw yuav siv tau tsuas yog tom qab lub Circuit Court breaker qhib thiab lub caij nplooj ntoos hlav recharges.
Qhov zoo:
Cov qauv yooj yim, tsis tas yuav txuas hluav taws xob ntxiv lossis txuas txuas ntxiv.
Txo tus nqi.
Qhov tsis zoo:
Nws tsis tiv thaiv lub kaw coil los ntawm kev kub hnyiab los ntawm kev kaw lub sijhawm ntev. Txawm hais tias lub tshuab tsis ua haujlwm, lub teeb liab kaw ntev ntev tuaj yeem ua rau lub kaw lus kaw kom muaj zog thiab hlawv tawm.
Kev ntseeg siab ntawm kev tiv thaiv -tripping mechanism yog nyob ntawm qhov tseeb machining thiab hnav ntawm cov khoom siv tshuab.
Cov qauv hluav taws xob feem ntau tsis xav txog kev siv tshuab ua haujlwm nkaus xwb los tiv thaiv -tripping kev txhim khu kev qha tiv thaiv -tripping ntsuas.
Xaus
Rau lub tshuab nqus tsev vacuum breakers, qhov kev ntseeg siab tshaj plaws thiab pom zoo los tiv thaiv -tripping tov yog "series (tam sim no- pib, voltage- tuav) hluav taws xob tiv thaiv -tripping circuit." Qhov no suav hais tias yog tus qauv yuav tsum tau ua thaum tsim, tsim kho, thiab ua haujlwm thiab tu.
Kub muag khoom
VTZ-12CL series sab hauv tsev txhaum ceev-txiav lub tshuab nqus tsev Circuit Court breakertsim los ntawmShaanxi West Fais Fab Tongzhong Hluav Taws Xob Co., Ltd.yog ib qho kev hloov pauv hauv tsev tsim los siv nrog qhov ntsuas hluav taws xob ntawm 12kV thiab AC 50 / 60Hz. Nws siv ib qho tshwj xeeb tsim cov hlau nplaum ruaj khov mechanism thiab repulsion mechanism ua ke. Thaum lub sijhawm ua haujlwm ib txwm, cov hlau nplaum ruaj khov ua haujlwm ua haujlwm ib txwm ua rau kaw thiab qhib. Thaum muaj kev txhaum tam sim no, lub Circuit Court breaker sai sai qhib ntawm lub repulsion mechanism nyob rau hauv lub nrhiav kom tau thiab tswj ntawm lub hwj chim system los tiv thaiv lub hwj chim system. Cov khoom tsim nyog rau ntau yam kev lag luam thiab kev lag luam mining thiab cov khoom siv hluav taws xob. Lub trolley chav tsev yog siv ua ke nrog covKYN28A-12 switchgear.Nws kuj tseem siv tau los ua ib qho chaw ruaj khov nrog cov khoom siv sib txuas sib txuas rau cov khoom ruaj ruaj xws liXGN 2.
