Yog vim li cas rau nrov Contactor khiav suab nrov

Lub suab nrov dhau thaumtus contactorkev ua haujlwm yog ib qho txhaum cai, feem ntau yog tshwm sim los ntawm kev sib cuag tsis zoo thiab kev co thaum lub sij hawm kev koom tes ntawm cov tsiv thiab nyob ruaj ruaj hlau cores. Nws cov hauv paus ntsiab lus tuaj yeem muab faib ua electromagnetic, mechanical, installation, thiab ib puag ncig yam. Qhov no tsis yog tsuas yog cuam tshuam rau qhov chaw ua haujlwm tab sis kuj tseem qhia tau tias cov khoom siv tsis ua haujlwm lossis lub neej luv luv.

Common Causes thiab Solutions:

Cov teeb meem tseem ceeb

1. tawg lossis tshem tawm luv luv- lub nplhaib hluav taws xob: Qhov no yog ib qho ua rau muaj suab nrov hauv AC contactors.

2. Cov qias neeg, xeb, lossis oily core ncej nto: Ua rau tsis zoo ntawm cov contactor nto.

3. Hnav, tsis sib luag, lossis tsis zoo ntawm cov ncej ncej: Ua rau muaj kev sib tsoo thiab kev vibrations thaum sib cuag.

4. Loose core fastening screws: Ua rau muaj kev vibration thaum ua haujlwm.

Kev daws:

1. Hloov nrog luv luv - lub nplhaib hluav taws xob ntawm tib qhov tshwj xeeb.

2. Ntxuav cov ncej nrog ib daim ntaub paj rwb dampened nrog anhydrous cawv los yog roj av.

3. Yog tias qhov tsis sib xws hnyav, hloov cov tub ntxhais; me me unevenness yuav smoothed nrog nplua sandpaper.

4. Txheeb xyuas thiab ceev cov clamping screws ntawm cov cores txav thiab ruaj khov.

 

Installation thiab Machinery

1. Kev teeb tsa tus contactor tsis raug: xws li qhov tsis sib xws mounting nto los yog xoob screws.

2. Cov khoom txawv teb chaws sab hauv: Cov plua plav lossis cov khoom me me daig hauv cov khoom txav.

3. Kev ua kom tsis zoo ntawm cov khoom txav: xws li obstructed armature txav.

4. Siab dhau ntawm lub caij nplooj ntoos hlav tiv tauj lossis rov qab caij nplooj ntoos hlav.

Kev daws:

1. Xyuas kom ruaj ntseg installation thiab ib lub phaj tiaj tiaj.

2. Ntxuav sab hauv tom qab fais fab tuag.

3. Kho lossis hloov cov khoom muaj feem cuam tshuam.

4. Kho lossis hloov lub caij nplooj ntoos hlav haum.

 

Teeb meem hluav taws xob

1. Coil tswj voltage tsawg dhau: ua rau kev nqus tsis txaus thiab cov tub ntxhais tsis muaj zog.

2. Coil tswj voltage siab dhau: muaj peev xwm ua rau muaj kev cuam tshuam ntau dhau ntawm cov tub ntxhais.

Kev daws: Ntsuas qhov voltage hla lub kauj thiab kho nws mus rau qhov ntsuas kev ua haujlwm.

 

Environmental Factors

1. Ib puag ncig kev co: kev vibration los ntawm cov khoom nyob ze yog kis mus rau tus contactor, ua rau resonance.

2. Ib puag ncig hnyav: plua plav, av noo, thiab corrosive gases ua kom lub cev muaj zog.

Fais fab tuag, xyuas, zawm, huv si, tiv thaiv xeb, thiab dampen vibrations.

 

Tsis tu ncua plua plav lub txee tswj hluav taws xob, zawm cov ntsia hlau, thiab ua kom lub zog ruaj khov hluav taws xob yog txoj hauv kev zoo los tiv thaiv cov teeb meem zoo li no. Rau cov contactors siv nyob rau hauv cov ntaub ntawv tseem ceeb los yog cov uas tsis tu ncua emit suab nrov txawv txav, nws yog pom zoo kom hloov lawv tam sim ntawd los tiv thaiv overheating thiab burnout ntawm lub kauj vim tsis zoo core kev koom tes, los yog ntau malfunctions tshwm sim los ntawm kev sib cuag tsis zoo ntawm cov neeg. Nco ntsoov: Nco ntsoov xyuas kom meej tias cov khoom siv hluav taws xob raug txiav tag nrho ua ntej ua haujlwm. High-voltage lossis complex circuits yuav tsum tau ua los ntawm cov neeg ua haujlwm tsim nyog.
