Distribution Transformer Thiab Fais Fab Transformer Fault Analysis
Cov kev ua tsis tau zoo ntawm kev faib hluav taws xob thiab lub zog hloov hluav taws xob hauv kev ua haujlwm suav nrog kev ua tsis tiav ntawm windings, bushings, kais hloov pauv, hlau cores, roj tso tsheb hlau luam thiab lwm yam khoom siv.
Winding txhaum
Feem ntau suav nrog inter-tig luv luv Circuit Court, winding grounding, interphase luv Circuit Court, disconnection thiab qhib vuam ntawm cov pob qij txha, thiab lwm yam.
Casing tsis ua hauj lwm
Lub fouling ntawm transformer bushing yuav ua rau muaj kuab paug flashover nyob rau hauv hnyav pos huab los yog lub teeb los nag, uas yuav ua rau ib tug-theem grounding los yog luv luv-circuit ntawm theem nyob rau hauv high-voltage sab ntawm lub transformer thiab lub hwj chim transformer.
Loj heev
Cov roj to ntawm cov khoom siv hluav taws xob thiab hluav taws xob hloov pauv yog qhov hnyav lossis txuas ntxiv dhau los ntawm qhov puas lawm kom cov roj qib tsis tuaj yeem pom ntawm cov roj ntsuas ntsuas. Thaum lub sij hawm no, lub transformer yuav tsum tau nres tam sim ntawd los kho qhov to thiab refuel. Qhov ua rau cov roj to ntawm lub transformer yog weld cracking los yog sealing Parts tsis ua hauj lwm, thiab cov roj tank yog heev corroded thiab puas los ntawm kev co thiab sab nraud quab yuam thaum ua hauj lwm.
Coj mus rhaub changer
Cov kev ua txhaum feem ntau suav nrog kev sib cuag tsis zoo lossis qhov tsis raug ntawm qhov hloov pauv ntawm tus kais dej, melting thiab hlawv ntawm qhov chaw sib cuag, thiab tso tawm ntawm cov neeg sib cuam tshuam lossis tso tawm ntawm txhua tus kais dej.
Overvoltage
Thaum lub transformer faib thiab lub hwj chim transformer nyob rau hauv lub lag luam raug ntaus los ntawm xob laim, vim lub siab muaj peev xwm ntawm xob laim, nws yuav ua rau sab nraud overvoltage ntawm lub transformer. Thaum qee qhov tsis zoo ntawm lub zog hluav taws xob hloov pauv, vim yog electromagnetic oscillation, nws yuav ua rau sab hauv overvoltage ntawm lub transformer. Feem ntau ntawm cov kev puas tsuaj los ntawm cov khoom siv overvoltage yog qhov kev puas tsuaj ntawm lub ntsiab rwb thaiv tsev ntawm cov winding, uas ua rau transformer tsis ua haujlwm.
Hlau tub ntxhais
Feem ntau ntawm qhov ua tsis tiav ntawm cov tub ntxhais hlau yog tshwm sim los ntawm kev puas tsuaj ntawm cov tub ntxhais hlau los yog cov ntsia hlau clamping ntawm cov tub ntxhais hlau.
Roj xau
Yog hais tias cov roj theem ntawm transformer transformer thiab lub hwj chim transformer roj tsawg dhau lawm, lub bushing lead hlau thiab tus kais hloov pauv yuav raug rau saum huab cua, thiab lub rwb thaiv tsev theem yuav raug txo kom tsawg, yog li nws yog ib qho yooj yim los ua kom tawg tawm.
