Roj Txias Distribution Transformer Siv

Lub transformer feem ntau yog tsim los ntawm cov tub ntxhais hlau, winding, roj tank, roj conservator, insulating bushing, kais changer thiab roj relay.

1. Roj Txias Distribution Transformer Iron Core

Cov tub ntxhais hlau yog qhov sib nqus Circuit Court ntawm lub transformer. Thaum lub sijhawm ua haujlwm, hysteresis poob thiab eddy tam sim no poob yuav raug tsim los ua kom muaj cua sov.

Yuav kom txo tau cov cua sov thiab txo qhov ntim thiab qhov hnyav, cov tub ntxhais hlau yog ua los ntawm cov ntawv txias-kuav los tiag-qhib silicon steel ntawv nrog lub siab sib nqus permeability tsawg dua 0.35mm. Raws li kev npaj ntawm winding nyob rau hauv cov tub ntxhais hlau, muaj hlau core hom thiab hlau plhaub hom.

Nyob rau hauv loj-muaj peev xwm transformers, thiaj li yuav xyuas kom meej tias lub tshav kub generated los ntawm cov tub ntxhais poob yuav tsum tau tag nrho tshem tawm los ntawm cov insulating roj thaum lub sij hawm ncig mus cuag ib tug zoo txias nyhuv, ib tug txias roj passage feem ntau muab nyob rau hauv lub hlau core.

2. Roj Txias Distribution Transformer Winding

Windings thiab cores yog cov tseem ceeb ntawm lub transformer. Vim yog qhov tsis kam ntawm winding nws tus kheej los yog kev sib cuag ntawm qhov sib koom ua ke, cov cua sov yuav raug tsim los ntawm I2Rt.

Yog li ntawd, lub winding tsis tuaj yeem hla qhov tam sim no siab tshaj qhov ntsuas tam sim no rau lub sijhawm ntev. Tsis tas li ntawd, thaum lub caij luv-circuit tam sim no dhau mus, lub zog hluav taws xob loj yuav raug tsim los ntawm winding thiab transformer yuav puas. Muaj ob hom kev windings: concentric thiab overlapping.

Lub ntsiab faults ntawm transformer windings yog inter-tig luv luv Circuit Court thiab luv luv Circuit Court rau plhaub. Tig-rau-tig luv luv Circuit Court feem ntau yog vim kev laus ntawm rwb thaiv tsev, los yog vim lub overload ntawm lub transformer thiab cov neeg kho tshuab puas tsuaj ntawm rwb thaiv tsev thaum lub sij hawm luv luv Circuit Court.

Cov roj theem nyob rau hauv lub transformer poob, yog li ntawd thaum lub winding raug rau cov roj theem, ib tug inter-tig luv Circuit Court kuj tshwm sim; Nyob rau hauv tas li ntawd, thaum muaj ib tug luv luv Circuit Court, lub winding yog deformed vim overcurrent nyhuv, ua rau lub rwb thaiv tsev yuav mechanically puas, thiab inter-tig luv luv Circuit Court kuj yuav tshwm sim.

Thaum muaj luv luv Circuit Court ntawm lem, tam sim no nyob rau hauv lub luv luv-circuit winding tej zaum yuav tshaj tus nqi ntsuas, tab sis tam sim no ntawm tag nrho cov winding yuav tsis tshaj tus nqi ntsuas. Hauv qhov no, kev tiv thaiv roj ua haujlwm, thiab thaum qhov xwm txheej hnyav, cov khoom siv tiv thaiv sib txawv kuj tseem yuav ua haujlwm.

Yog vim li cas rau lub luv luv Circuit Court rau lub plhaub kuj yog vim kev laus ntawm rwb thaiv tsev los yog roj damp, roj theem poob, los yog vim hluav taws xob thiab kev khiav hauj lwm overvoltage.

Tsis tas li ntawd, thaum ib qho luv luv Circuit Court tshwm sim, lub winding yog deformed vim overcurrent, thiab luv luv Circuit Court rau casing yuav tshwm sim. Thaum lub plhaub luv luv, cov khoom siv tiv thaiv roj thiab kev tiv thaiv hauv av feem ntau yog qhib.

3. Roj Txias Distribution Transformer Roj tank

Lub cev (winding thiab hlau core) ntawm cov roj-immersed transformer yog ntsia rau hauv lub tank roj uas muaj roj transformer, thiab cov roj tank yog welded nrog steel daim hlau. Cov roj tank ntawm nruab nrab thiab me transformers yog tsim los ntawm lub tank plhaub thiab lub tank npog. Lub cev ntawm lub tshuab hloov pauv tau muab tso rau hauv lub plhaub tank, thiab lub tank npog tuaj yeem nqa tawm rau kev saib xyuas.
