I. Cov ntsiab lus tseem ceeb rau Ntev -Lub Sij Hawm Lub Sij Hawm Caij Nplooj Ntoos Hlav-Mechanism VCB

Long-Term Lifespan Of Spring-Mechanism Vacuum Circuit Breakers

Caij nplooj ntoos hlav ua haujlwm Mechanism

Lub caij nplooj ntoos hlav tshuab khaws lub zog los ntawm cov tshuab nqus dej (compression lossis torsion springs) thiab tso tawm lub zog no los ntawm cov txheej txheem sib txuas, lub zog, thiab cov cams kom tsav lub Circuit Court breaker qhib thiab kaw.

1. Core Maintenance Focus: Precision Maintenance of the Mechanical System

Lubrication tsis tu ncua: Ua raws li cov neeg tsim khoom xav tau, siv cov roj tshwj xeeb qis -cov roj kub (xws li Molykote lossis sib npaug) ntawm kev sib txhuam tseem ceeb xws li kev sib txuas sib txuas, cov kabmob, lub zog, thiab cov hlua khi. Rau qhov kub thiab txias ib puag ncig, xaiv cov khoom uas tsim nyog rau huab cua tsis kam.

Bolt Tightness Inspection: Kev vibration tuaj yeem yooj yim ua rau xoob ntawm cov khoom siv sib txuas. Tsis tu ncua xyuas thiab nruj tag nrho cov txheej txheem bolts rau tus qauv torque, tshwj xeeb tshaj yog cov kev sib txuas ntawm chassis thiab cov ntsiab lus kho mechanism.

Caij nplooj ntoos hlav Fatigue Monitoring: Kaw springs yog nquag qaug zog los yog yas deformation tom qab nquag ua haujlwm. Nws raug nquahu kom ua lub caij nplooj ntoo hlav mus ncig lossis kev sim siab, piv nrog cov ntaub ntawv hauv lub Hoobkas, thiab hloov tam sim yog qhov sib txawv tshaj qhov txwv.

Kaw thiab Qhib Tsis Siv Tshuaj Ntsuam Xyuas: Kev laus, tawg, los yog tawg hydraulic lossis polyurethane buffers tuaj yeem ua rau muaj kev cuam tshuam ntau heev thiab kev puas tsuaj rau cov khoom siv . 1. Xyuas kom cov nyhuv buffering txaus, tsis muaj kev cuam tshuam los yog nruj.

2. Qhov tseem ceeb Parameter saib xyuas thiab hloov kho

Kaw thiab qhib ceev thiab sijhawm: ntsuas tsis tu ncua siv lub ntsuas hluav taws xob ntsuas hluav taws xob. qeeb qeeb qeeb yuav ncua lub sij hawm arcing, hlawv cov neeg sib cuag; ceev ceev heev yuav ua rau muaj kev cuam tshuam ntau heev, shortening mechanical life. Kho nruj me ntsis raws li kev ua haujlwm ntau.

Stroke thiab Overtravel Measurement: Kev sib cuag tsis txaus yuav ua rau muaj kev sib cuag tsis txaus, muaj zog tiv thaiv, thiab overheating; overtravel overtravel yuav ua rau kom lub caij nplooj ntoos hlav load. Ntsuas tsis tu ncua thiab kho raws li tus qauv muaj nuj nqis.

Mechanical Characteristic Curve Analysis: Npaj "stroke-time" nkhaus siv lub tachometer thiab muab piv nrog tus qauv nkhaus. Cov duab nkhaus txawv txav feem ntau yog cov cim qhia ntxov ntawm jamming, lubrication tsis zoo, lossis cov khoom hnav.

3. Environmental and Operational Adaptability Optimization

Plua plav thiab noo noo tiv thaiv: Lub tshuab lub thawv sealing sawb yuav tsum zoo kom tsis txhob muaj plua plav paug ua rau jamming thiab noo noo ua rau corrosion. Xav txog kev txhim kho lub tshuab hluav taws xob los tiv thaiv -condensation.

Kev Tswj Xyuas Zaus: Tsis txhob ua haujlwm tsis tu ncua (xws li rov qhib thiab kaw thaum lub sijhawm ua haujlwm).

Rau cov ntawv thov nrog kev ua haujlwm tsis tu ncua (xws li metallurgy thiab steel dov), lub voj voog tu yuav tsum tau luv luv raws li.

Energy Storage Motor Maintenance: Kos lub cev muaj zog carbon txhuam thiab gearbox kom paub meej lub zog cia lub sij hawm. Nres kev ua haujlwm tam sim ntawd tom qab lub zog cia ua tiav los tiv thaiv lub cev muaj zog dhau.

II. Cov ntsiab lus tseem ceeb rau Ntev -Lub Sij Hawm Lub Sij Hawm ntawm Cov Hlau nplaum tas mus li vCB

Permanent Magnet Mechanism VCB

Cov ntsiab lus tseem ceeb rau kev ua neej ntev ntawm Cov Hlau nplaum ruaj khov Lub Nqus Hluav Taws Xob Hluav Taws Xob Cov hlau nplaum ruaj khov siv cov hlau nplaum ruaj khov thiab cov hlau nplaum hluav taws xob los ncaj qha tsav cov kev sib cuag, txo qis cov khoom thiab tshem tawm cov khoom siv sib txuas sib txuas.

Long-Term Lifespan Of Permanent Magnet Vacuum Circuit Breakers

1. Core Maintenance Focus: Reliability of Electrical and Control Systems

Capacitor Condition Monitoring: Lub zog cia capacitor yog "lub plawv" ntawm cov hlau nplaum ruaj khov mechanism.

Tsis tu ncua xyuas nws cov capacitance, leakage tam sim no, thiab sab hauv tsis kam.

Txo qhov peev xwm yuav ua rau tsis txaus kaw nrawm, thiab cov dej xau tam sim no yuav ua rau lub sijhawm them nyiaj luv luv.

Nws raug nquahu kom muaj kev soj ntsuam kev tshaj lij txhua 3-5 xyoos lossis raws li tus naj npawb ntawm kev ua haujlwm, thiab hloov cov capacitors kev laus ntxov ntxov.

Tswj Fais Fab Kev Tswj Xyuas Zoo: Siv cov khoom siv hluav taws xob tswj thiab lim DC.

Kev hloov pauv ntawm qhov hluav taws xob ntau dhau los yog ripple tuaj yeem ua rau lub zog tsav thiab coils, ua rau lub neej luv luv ntawm cov khoom siv hluav taws xob.

Dual-coil check tam sim no: Ntsuas qhov ntsuas qhov tseem ceeb ntawm qhov qhib thiab kaw coils thiab sib piv nrog cov nqi pib.

Cov kev hloov pauv hauv kev tiv thaiv yuav qhia tau luv luv ntawm cov kauj hloov los yog kev laus ntawm cov khoom sib txuas.

Txoj hauj lwm sensor calibration: Xyuas kom tseeb qhov tseeb ntawm qhov qhib/kaw txoj hauj lwm sensor (sib sib zog nqus hloov los yog auxiliary contact) teeb liab.

Cov teeb liab cuav tuaj yeem ua rau tus tswj cov logic yuam kev, ua rau muaj kev ua haujlwm tsis zoo lossis tsis ua haujlwm.

2. Qhov tseem ceeb Parameters thiab Software Maintenance

Kev saib xyuas tus yam ntxwv: Txawm hais tias qhov tsis sib xws ntawm cov hlau nplaum ruaj khov yog qhov ruaj khov, lub sijhawm qhib thiab kaw thiab synchronization tseem yuav tsum tau kuaj xyuas ib ntus.

Anomalies feem ntau taw qhia txog teeb meem nrog cov tswj Circuit Court lossis capacitors.

Software thiab firmware hloov tshiab: Rau cov tswj ntse, ua tib zoo saib xyuas cov firmware hloov kho tshiab tso tawm los ntawm cov chaw tsim khoom, uas tuaj yeem suav nrog kev ua kom zoo dua qub uas tuaj yeem tswj hwm cov khoom siv hluav taws xob zoo dua thiab kev tso tawm, txuas ntxiv tag nrho lub neej.

Sib nqus Circuit Court tuav: Nyob rau hauv huab cua kub los yog muaj zog vibration ib puag ncig, xyuas seb qhov kev pheej hmoo ntawm demagnetization ntawm cov hlau nplaum ruaj khov (qhov no tuaj yeem txiav txim ncaj qha los ntawm kev tuav lub zog).

Tsis txhob muaj kev cuam tshuam loj lossis siab - ib puag ncig kub.

3. Kev tiv thaiv ib puag ncig thiab kev tiv thaiv

Electromagnetic Compatibility (EMC): Cov hlau nplaum tas mus li muaj ntau yam khoom siv hluav taws xob, yuav tsum muaj kev tiv thaiv zoo thiab hauv av los tiv thaiv electromagnetic cuam tshuam los ntawm kev tswj tsis tau.

Temperature Control: Controllers thiab capacitor yog qhov kub thiab txias. Xyuas kom muaj qhov cua zoo nyob rau hauv lub tshuab kaw lus thiab tsis txhob raug tshav ntuj ncaj qha los yog nyob ze rau qhov chaw kub siab -.

Simplified Maintenance: Siv tag nrho nws "kev tu vaj tu tsev- dawb" kom zoo dua, tab sis tsis yog "kev tu- dawb." Hloov qhov ua kom pom tseeb los ntawm "kev kho tshuab" mus rau "kev saib xyuas qhov xwm txheej thiab kev saib xyuas kev kwv yees."

General Long -Lub Neej Core Strategy (tseem siv tau rau ob hom kev siv tshuab)

Vacuum Interruptor Protection:

Ua qhov ntsuas lub tshuab nqus tsev tsis tu ncua (piv txwv li, lub zog zaus tiv thaiv qhov ntsuas hluav taws xob) kom ntseeg tau tias lub tshuab nqus tsev yog 10⁻⁴ Pa lossis siab dua.

Tswj kev sib tw dhia thiab kaw ua ntej - tawg, vim cov no yog cov laj thawj tseem ceeb ntawm kev sib cuag burnout.

Tsis txhob cuam tshuam luv luv -circuit tam sim no tshaj cov nqi ntsuas; txawm tias ib qho hnyav dhau heev tuaj yeem ua rau cov khoom sib cuag mus tas li.

Kev saib xyuas kev sib txuas hluav taws xob nruj: Kev ntsuas kub tsis tu ncua (infrared thermography), nruj ntawm cov kev sib txuas ntawm cov thawj busbar thiab lwm cov terminals kom tiv thaiv overheating thiab oxidation.

Cov xwm txheej-raws li kev kwv yees kev saib xyuas: Tso tseg qhov ruaj khov- kev tu lub voj voog, ua haujlwm hauv online xyuas cov tshuab (xws li kev saib xyuas tus yam ntxwv, kev ntsuas kub, thiab ntsuas ntsuas lub tshuab nqus tsev), cov ntaub ntawv- tau tsav, thiab kev cuam tshuam meej.

Kev ua haujlwm tshaj lij thiab kev cob qhia: zam kev ua haujlwm hnyav xws li phau ntawv qhib thiab kaw thaum muaj xwm ceev. Xyuas kom cov neeg ua haujlwm nkag siab txog cov txheej txheem ntawm cov khoom siv.
