Dab tsi faults yog nquag tshwm sim nyob rau hauv kev siv cov nruab nrab zaus induction cua sov fais fab mov

1. Tom qab cov khoom siv tau ua haujlwm ib txwm ua rau lub sijhawm, cov khoom siv muaj suab txawv txav, kev nyeem ntawv ntawm lub ‘meter’ yog co, thiab cov khoom siv tsis ruaj khov.

Yog vim li cas: Cov yam ntxwv thermal ntawm cov khoom siv hluav taws xob tsis zoo

Kev daws teeb meem: Cov khoom siv hluav taws xob tuaj yeem muab faib ua ob ntu: tsis muaj zog tam sim no thiab muaj zog tam sim no, thiab kuaj cais. Kev txheeb xyuas qhov kev tswj hwm thawj zaug tuaj yeem tiv thaiv kev puas tsuaj rau cov khoom siv hluav taws xob tseem ceeb. Thaum lub hwj chim tseem ceeb hloov tsis tau qhib, tsuas yog qhib lub hwj chim ntawm qhov chaw tswj. Tom qab tswj kav ua haujlwm rau ib lub sijhawm, siv ib lub sijhawm oscilloscope los xyuas cov mem tes ntawm cov mem tes tswj tau ib txwm.

2. Cov cuab yeej ua haujlwm ib txwm ua, tab sis nquag overcurrent.

Yog vim li cas: Saib seb nws yog vim qhov tsis raug xaim uas ua rau muaj kev cuam tshuam electromagnetic thiab parasitic parameter coupling cuam tshuam ntawm kab.

tshuaj:

(1) Cov xov hlau muaj zog thiab cov xov tsis muaj zog tau muab tso ua ke;

(2) Cov kab hluav taws xob zaus thiab kab nruab nrab nruab nrab tau tso ua ke;

(3) Cov xaim hluav taws xob txuas nrog cov xov hlau muaj zog, cov xov hlau nruab nrab zaus, thiab cov npav npav.

3. Cov cuab yeej siv tau ua haujlwm ib txwm, tab sis thaum lub sijhawm ua haujlwm tiv thaiv overcurrent, ntau KP thyristors thiab cov fuses ceev tau hlawv.

Yog vim li cas: Thaum lub sij hawm overcurrent tiv thaiv, thiaj li yuav tso tawm lub zog ntawm smoothing reactor rau daim phiaj, lub rectifier choj hloov los ntawm lub rectification xeev mus rau lub inverter xeev.
