Yog vim li cas rau overheating ntawm Cheebtsam nyob rau hauv lub Distribution Box

Overheating ntawm cov khoom hauv hluav taws xobcov thawv xa khoomyog ib qho tshwm sim uas yuav tsum tau ua tib zoo saib xyuas. Nws tuaj yeem muab faib ua ob hom: ib txwm overheating thiab txawv txav overheating. Kev kub ntxhov txawv txav yog ib qho tseem ceeb zais qhov phom sij ntawm hluav taws xob hluav taws xob thiab yuav tsum tau tshawb xyuas thiab kho tam sim ntawd.

I. Kev sib txuas tsis raug

Cov no feem ntau tshwm sim ntawm kev sib txuas ntawm cov xov hlau thiab cov khoom.

1. Loose Screws: Screws tsis tau nruj thaum lub sij hawm installation, los yog loosened vim thermal expansion thiab contraction los yog vibration tom qab ntev - lub sij hawm ua hauj lwm. Qhov no ua rau muaj kev tiv thaiv kev tiv thaiv, ua kom muaj cua sov ntau thaum tam sim no ntws.

2. Kev xaim tsis raug: Burrs, oxidation, lossis rwb thaiv tsev nias rau hauv lub davhlau ya nyob twg txo qhov kev sib cuag zoo.

Cov hlua tooj liab tsis tsim nyog tau siv, lossis kev sib txuas tsis ruaj ntseg.

Untinned los yog substandard tus pin terminals tau siv, ua rau ib nrab sib cais thiab kev sib cuag tsis zoo.

3. Loose los yog Insipid Connections: Qhov kev sib txuas zoo nkaus li tau ua, tab sis qhov tseeb kev sib cuag yog me me, ua rau muaj kev tiv thaiv siab heev.

II. Load-Cov teeb meem ntsig txog

1. Overload: Tam sim no ntws los ntawm lub voj voog lossis cov khoom siv tshaj nws qhov ntsuas tam sim no - nqa peev xwm rau lub sijhawm ntev. Piv txwv li, siv ntau dhau - cov khoom siv fais fab lossis siv cov xov hlau nyias nyias. Qhov tam sim no tshaj qhov tsim muaj peev xwm, ua rau cov khoom siv thiab cov xaim hluav taws xob ua haujlwm ntawm kev siv siab tsis tu ncua thiab ua kom muaj cua sov.

2. Load Imbalance (Peb-Phase System): Kev faib tsis sib npaug ntawm peb-theem loads ua rau muaj ntau dhau tam sim no hauv ib theem, ua rau overheating ntawm cov kab sib txuas thiab cov khoom siv hloov pauv.

3. Harmonic Currents (Common in Commercial and Industrial Applications): High -frequency harmonic currents generated by nonlinear loads tsub kom qhov zoo tam sim no ntawm txoj kab, ua rau cov cua kub tsis zoo ntawm cov kab nruab nrab thiab cov khoom siv.

III. Teeb meem nrog cov Cheebtsam Lawv tus kheej

1. Cov khoom puas los yog laus:
Kev sib cuag sab hauv tuaj yeem raug hlawv lossis oxidized, ua rau muaj kev tiv thaiv ntau ntxiv.

Cov txheej txheem kev laus ua rau kev ua haujlwm qeeb, tsis txaus sab hauv, thiab kev sib cuag tsis zoo.

Tsawg rwb thaiv tsev kev ua tau zoo tsub kom cov hluav taws xob sab hauv, ua kom muaj cua sov.

Cov yam ntxwv tsis sib xws, xws li kev siv lub tshuab hluav taws xob uas muaj qhov ntsuas qis tam sim no los tswj lub siab load.

2. Kev xaiv cov khoom tsis raug:
Rated tam sim no tsawg dua qhov load tam sim no, tawg peev xwm tsis txaus, los yog cov khoom tsis zoo, ua los ntawm cov khoom tsis zoo, lossis muaj kev ua haujlwm tsis zoo.

IV. Environmental thiab Installation teeb meem

1. Tsis zoo cua sov Dissipation:
Lub thawv xa khoom yog ntsia rau hauv qhov chaw tsis zoo, qhov chaw kaw.

Cheebtsam yog tuab heev ntim rau hauv lub thawv, ua rau kub tsub zuj zuj.

Lub thawv yog npog lossis thaiv los ntawm cov khib nyiab.

2. Kub Ambient Kub:
Kev teeb tsa hauv qhov chaw siab - qhov kub thiab txias xws li chav boiler lossis lub hnub ci ncaj qha ua rau muaj qhov kub thiab txias.

3. Corrosive Gases lossis hmoov av:
Qhov chaw ntub dej, plua plav, lossis corrosive ib puag ncig ua kom sib koom ua ke oxidation thiab rwb thaiv tsev laus.

Kev ntsuas kub tsis tu ncua, siv cov khoom tsim nyog, cov txheej txheem kev teeb tsa, thiab kev faib khoom kom raug yog qhov tseem ceeb rau kev tiv thaiv overheating malfunctions. Yog tias pom tias muaj cua sov tsis zoo, tus kws tshaj lij hluav taws xob yuav tsum raug hu tam sim los tshawb xyuas thiab daws qhov teeb meem, tiv thaiv cov teeb meem ua ntej lawv tshwm sim.
