Raws li cov kws tshaj lij hauv kev lag luam fais fab, feem ntau ntawm peb paub txogLub tshuab nqus tsev Circuit Court breakerslos yog tsawg kawg tau hnov txog lawv. Lawv muaj qhov loj me, lub cev nyhav, tsim nyog rau kev ua haujlwm nquag, thiab kev saib xyuas -dawb arc quenching. Nrog kev nce qib hauv cov txheej txheem tsim khoom, kev ua tsis tiav hauv lub tshuab nqus tsev arc tau raug txo qis; Txawm li cas los xij, cov teeb meem kev ua haujlwm tseem niaj hnub tshwm sim hauv cov txheej txheem khiav haujlwm. Kab lus no tham txog qee qhov kev ua tsis tiav ntawm Circuit Court breaker thiab lawv cov laj thawj, nrog kev cia siab tias nws yuav pab tau rau txhua tus.
I. Vacuum Arc Chamber Failures: Feem ntau Gas Leaks
Kev Tiv Thaiv thiab Kev Tshuaj Xyuas:Ua lub zog- zaus tiv thaiv qhov ntsuas hluav taws xob ua ntej ua haujlwm los xyuas qhov ntsuas lub tshuab nqus tsev thiab kev ua haujlwm rwb thaiv tsev.It is recommended to perform another withstand voltage test within six months of commissioning to detect leaking tubes as early as possible.Kev tshuaj xyuas tom ntej tuaj yeem ua raws li cov qauv ntsuas txhua xyoo.
II. Kev khiav hauj lwm Mechanism Failures
Cov tsos mob ua tsis tiav suav nrog kev kaw / qhib kev ua haujlwm tsis zoo thiab hlawv - tawm coils. Cov hauv paus ntsiab lus tuaj yeem muab faib ua hluav taws xob Circuit Court thiab mechanical teeb meem.1. Short Circuit:Kev ua haujlwm tsis ua haujlwm thaum lub zog muaj zog, uas tuaj yeem ua rau lub tshuab hluav taws xob, cov khoom muag muag, lossis hlawv - tawm cov khoom. Ua rau: Cov kab hluav taws xob tsis raug, thauj cov coils tsis txuas, xoob hauv kev sib txuas, lossis cov khoom siv hluav taws xob puas los ntawm kev cuam tshuam sab nraud.2. Circuit Breaker tsis ua haujlwm (tsis yog-kev koom tes lossis tsis ua haujlwm).Ua rau: Tsis muaj qhov hluav taws xob ntawm qhov kev khiav hauj lwm fais fab, qhib Circuit Court, tawg coil xov hlau, los yog kev sib cuag tsis zoo nyob rau hauv kev sib cuag hloov.3. Tsis ua hauj lwm hauv ib qho kev taw qhia (kaw lossis qhib).Ua rau: Misalignment ntawm pab hloov hu.4. Kev kaw tsis tiav, lossis qhib tam sim tom qab kaw. Ua rau:Kev khiav hauj lwm voltage tsawg dhau; kev mus ncig ntau dhau ntawm kev txav chaw sib cuag; kev tshem tawm ntxov ntxov ntawm kev pabcuam hloov pauv kev sib cuag; kev koom tes tsis txaus ntawm ib nrab -shaft thiab latch; Kev kho tsis raug ntawm "I" - zoo li lub phaj.5. Qhib tsis tau.Ua rau: Cov khoom txawv teb chaws cuam tshuam rau lub hauv paus; kev mus ncig ib nrab- ncej tsis tig dawb; lub phaj tooj liab yog ze rau tus ntaus ntawv; kev koom tes ntau dhau ntawm ib nrab -shaft thiab latch.6. Coil burnout:Kev hloov pauv hloov pauv tsis raws sijhawm; mechanical jamming tiv thaiv cov tub ntxhais los ntawm kev mus txog nws txoj haujlwm zoo; kev khiav hauj lwm voltage tsawg dhau. Tsis tas li ntawd, kev kub ceev ceev kuj tseem tuaj yeem tshwm sim los ntawm luv luv Circuit Court ntawm coil windings los yog rwb thaiv tsev degradation.
III. Cov lus pom zoo rau kev tu txhua hnub
Tsis tu ncua tshuaj xyuas cov neeg kho tshuab hloov tau yooj yim ntawm kev khiav hauj lwm mechanism thiab lub sij hawm ntawm kev pab cuam hloov kev sib cuag hloov; sim DC tsis kam thiab rwb thaiv tsev ntawm cov kauj ib xyoos ib zaug; ua raws sij hawm tiv thaiv qhov ntsuas hluav taws xob ntawm lub arc-extinguishing chamber. Hais txog tej yam txawv txav tam sim ntawd.
Cov ntsiab lus
Cov teeb meem kev khiav hauj lwm mechanism yog feem ntau ua rau lub tshuab nqus tsev Circuit Court breaker tsis ua hauj lwm. Rau arc-extinguishing chamber tsis ua hauj lwm, lub hom phiaj yuav tsum nyob rau thaum ntxov-theem tiv thaiv voltage ntsuas thiab hloov raws sij hawm; rau kev khiav hauj lwm mechanism tsis ua hauj lwm, hluav taws xob circuits thiab mechanical Cheebtsam yuav tsum tau soj ntsuam systematically raws li pom cov tsos mob. Kev ua raws li niaj hnub kev tiv thaiv kev saib xyuas tuaj yeem txhim kho kev ntseeg tau ntawm kev ua haujlwm.
