Kev daws rau Kaw bounce ntawm Nqus Circuit Court Breakers

Qhov kaw bounce ntawm lub tshuab nqus tsev vacuum breakers yog ib qho teeb meem tab sis nruj tswj tau, vim tias nws tuaj yeem ua kom muaj kev sib cuag, ua kom muaj hluav taws xob ntau dhau, thiab cuam tshuam rau ob qho tib si hluav taws xob thiab kev siv tshuab. Cov hauv qab no yog cov kev daws teeb meem thiab cov txheej txheem:

Mechanical Structure Optimization (qhov tseem ceeb mus kom ze):

Kev khiav hauj lwm mechanism optimization: Xyuas kom meej tias cov yam ntxwv ntawm cov kev khiav hauj lwm mechanism (xws li lub caij nplooj ntoos hlav mechanism, mus tas li hlau nplaum mechanism) phim lub load yam ntxwv ntawm lub Circuit Court breaker. Qhov kev kaw lub davhlau ya nyob twg yuav tsum tsis txhob siab dhau thiab yuav tsum maj mam li ua tau thaum ua kom ntseeg tau tias kaw. Tsis siv neeg tsim: Ntxiv los yog optimize hydraulic buffers los yog polyurethane tsis pads nyob rau thaum xaus ntawm lub tsiv kev sib cuag txav los yog nyob rau hauv lub kis tau tus mob txuas mus nqus cov seem kinetic zog, uas yog ib tug ntawm cov feem ntau ncaj qha thiab zoo txoj kev los txo bouncing. Txhim kho coaxiality thiab verticality: xyuas kom meej lub coaxiality ntawm kev txav thiab zoo li qub nyob rau hauv lub arc extinguishing chamber, nrog rau qhov nruab nrab thiab ntsug ntawm cov zis pas nrig ntawm kev khiav hauj lwm mechanism thiab txav kev sib cuag pas nrig ntawm lub arc extinguishing chamber, kom txo tau lateral cuam tshuam. Tightening thiab anti-loosing: Tshawb xyuas thiab zawm tag nrho cov khoom siv sib txuas (xws li pins, bolts) txhawm rau tiv thaiv kev vibration thib ob los ntawm kev xoob.

Hu rau System Design

Sib cuag Cov Khoom Siv thiab Cov Qauv: Siv los tiv thaiv - vuam thiab siab - cov khoom siv hluav taws xob xws li tooj liab -chromium (CuCr). Txhim kho qhov kev sib cuag zoo (xws li, siv cov kev sib cuag nrog qee qhov chaw arc) kom yooj yim rau kev sib cuag nrog zawv zawg thiab txo qhov kev sib tsoo ncaj qha thiab rov ua dua.

Hu rau Lub Caij Nplooj Ntoos Hlav: Ua kom zoo rau lub preload, txhav, thiab kev teeb tsa ntawm kev sib cuag lub caij nplooj ntoos hlav. Ua kom qhov kev sib cuag thawj zaug kom tsim nyog thiab xyuas kom meej tias lub caij nplooj ntoos hlav tuaj yeem ua kom muaj kev vibrations sai.

Hu rau Kev Taug Kev Mus Los thiab Kev Kho Kev Tshaj Tawm: Precisely adjust the overtravel. Tsis txaus overtravel yuav ua rau tsis txaus siab thiab nce bouncing; overtravel overtravel yuav ua rau kom muaj zog sib tsoo. Kev kho kom zoo yuav tsum tau ua raws li cov chaw tsim khoom cov kev qhia tshwj xeeb.

Tswj thiab ua haujlwm Parameter hloov

Kaw Voltage Control: xyuas kom meej tias lub kaw lus kaw ua haujlwm ntawm qhov ntsuas hluav taws xob. Cov hluav taws xob ntau dhau yuav ua rau lub zog kaw ntau dhau thiab nrawm, ua kom nrawm nrawm.

Kaw Phase Control (Yeem): Rau siab- kawg lossis ntse Circuit Court breakers, theem xaiv kaw tshuab tuaj yeem raug coj los kaw ze zero- hla qhov hluav taws xob, txo qhov cuam tshuam electrodynamic ntawm pre- tawg tam sim no ntawm cov neeg sib cuag thiab yog li txo qis bounce.

1. Diagnostic Measurement: Ua ntej, siv lub tshuab ntsuas tus yam ntxwv los ntsuas qhov ntsuas lub sij hawm bounce uas twb muaj lawm (feem ntau yog milliseconds, ms) thiab tus naj npawb ntawm bounces.

Xav txog Kev Txhim Kho Cov Txheej Txheem: Rau kev ua haujlwm nquag lossis tseem ceeb, yog tias tus qauv qub muaj qhov tsis zoo ntawm cov qauv tsim, xav txog kev hloov kho dua tshiab rau lub tshuab nqus tsev vacuum nrog kev ua haujlwm zoo dua.

2.Core tus qauv: Cov kev daws teeb meem kawg yuav tsum xyuas kom meej tias lub sijhawm kaw bounce ua raws li cov kev cai ntawm cov qauv tsim xws li GB/T 1984-2014 "High-Voltage AC Circuit Breakers" lossis IEC 62271-100 (feem ntau Tsawg dua lossis sib npaug li 2ms). Hauv kev ua haujlwm tiag tiag, nws yog qhov tseem ceeb uas yuav tsum tau xa mus rau cov ntawv qhia tshwj xeeb ntawm cov khoom tsim khoom.

VTZ-12KF Nqus Circuit Court Breaker(Tongzhong Hluav Taws Xob tshwj xeeb qauv) yog ib qho hluav taws xob sab hauv tsev rau cov ntsuas hluav taws xob 12kV, AC 50/60Hz. Nws adoptsmodular kev khiav hauj lwm mechanismthiab yog tsim rau ntau yam kev lag luam thiab mining lag luam thiab cov khoom siv hluav taws xob. Lub trolley chav tsev yog siv ua ke nrog covKYN28A-12 hloov txee. Nws kuj tseem siv tau los ua ib qho chaw ruaj khov thiab nruab nrog cov khoom sib txuas sib txuas rau XGN2 thiab lwm cov khoom ruaj khov.
