Feem ntau faults thiab teeb meem txoj kev ntawm high zaus quenching khoom
Common faults thiab troubleshooting txoj kev ntawm cov khoom siv hluav taws xob ntau zaus
1. Fault phenomenon Lub high-frequency quenching khoom ua hauj lwm ib txwm tab sis lub hwj chim tsis mus.
Yog tias cov cuab yeej ua haujlwm ib txwm muaj, nws tsuas tuaj yeem txhais tau tias lub zog ntawm txhua qhov ntawm cov khoom siv tsis zoo, thiab nws txhais tau tias kev hloov kho tsis raug ntawm cov khoom siv yuav cuam tshuam rau lub zog ntawm cov khoom siv.
Cov laj thawj tseem ceeb yog:
(1) Lub rectifier qhov tsis raug kho kom zoo, lub raj rectifier tsis qhib tag nrho thiab DC voltage tsis ncav cuag tus nqi ntsuas, uas cuam tshuam rau lub zog tso zis;
(2) Yog tias qhov nruab nrab zaus voltage tus nqi raug kho siab dhau lossis qis dhau, nws yuav cuam tshuam rau lub zog tso zis;
(3) Kev hloov tsis raug ntawm qhov txiav tawm thiab txiav tawm tus nqi ua rau lub zog tso zis tsawg;
(4) Qhov tsis sib haum xeeb ntawm lub qhov cub lub cev thiab lub zog hluav taws xob cuam tshuam rau lub zog tso zis;
(5) Yog tias lub capacitor them nyiaj tau teeb tsa ntau dhau lossis tsawg dhau, cov khoom siv hluav taws xob nrog cov hluav taws xob zoo tshaj plaws thiab thermal efficiency tsis tuaj yeem tau, uas yog, qhov zoo tshaj plaws kev lag luam hluav taws xob tsis tuaj yeem tau txais;
(6) Qhov sib faib inductance ntawm qhov nruab nrab zaus tso zis hluav taws xob thiab qhov inductance ntxiv ntawm cov hluav taws xob resonant yog qhov loj heev, uas tseem cuam tshuam rau lub zog siab tshaj plaws.
2. Qhov tshwm sim txhaum cai Cov cuab yeej siv hluav taws xob ntau zaus ua haujlwm ib txwm ua, tab sis thaum lub zog nce thiab txo qis hauv qee qhov hluav taws xob, cov cuab yeej muaj suab txawv txav thiab co co, thiab cov cuab yeej hluav taws xob qhia lub viav vias.
Qhov kev ua txhaum no feem ntau tshwm sim ntawm lub hwj chim muab potentiometer, thiab ib feem ntawm lub hwj chim muab potentiometer tsis dhia zoo, ua rau lub inverter tig rov qab thiab hlawv lub thyristor thaum cov cuab yeej tsis ruaj khov thiab hnyav.
