Yog vim li cas rau kev puas tsuaj rau hluav taws xob Arc rauv Thermal Capacitors

Hauv kev lag luam xws li steel smelting thiab alloy melting, hluav taws xob arc rauv yog cov khoom siv thauj khoom uas muaj zog noj, muaj kev cuam tshuam, thiab siab sib haum xeeb. Txhawm rau txhim kho lub zog ntawm lub zog, ua kom cov kab hluav taws xob ruaj khov, thiab txhim kho kev siv hluav taws xob, thermal capacitors feem ntau tau teeb tsa hauv arc rauv tshuab. Txawm li cas los xij, ntau tus neeg siv feem ntau ntsib qhov tsis ua haujlwm capacitor thaum ua haujlwm. Dab tsi yog qhov laj thawj rau qhov no?

I. Feem ntau yog vim li cas rau kev puas tsuaj rau hluav taws xob Arc rauv Thermal Capacitors

1. Kev puas tsuaj ntau dhau vim muaj kev sib haum xeeb ntau dhau
Cov hluav taws xob arc rauv yog cov khoom siv tsis zoo thiab tsim kom muaj qhov tseem ceeb ntawm siab -kev sib haum xeeb (tshwj xeeb tshaj yog 2nd, 3rd, 5th, 7th, thiab 11th harmonics) thaum ua haujlwm. Cov kev sib haum xeeb tam sim no superimpose rau ntawm lub capacitor, ua rau lawv tiv taus tam sim no tshaj lawv cov nqi ntsuas. Ntau dhau ntawm cov capacitor tam sim no ua rau muaj qhov nce hauv qhov kub thiab txias hauv dielectric thiab accelerates dielectric aging.

Cov lus pom zoo: Nruab cov lim dej reactors (feem ntau nrog tus nqi reactance ntawm 5% mus rau 14%) nyob rau hauv series nrog lub capacitor Circuit Court kom zoo suppress harmonic tam sim no thiab tiv thaiv cov capacitors los ntawm harmonic overload.

2. Grid Voltage Fluctuations thiab Arc Impact
Kev pib thiab tua ntawm arc rauv ua rau cov kab hluav taws xob hloov pauv loj heev thiab tseem tsim cov kev cuam tshuam voltages. Xws li kev rov ua dua siab dua -voltage kev ntxhov siab tuaj yeem ua rau lub zog hluav taws xob tawg, sab hauv metallized zaj duab xis txheej sib cais, casing bulging, roj to, thiab lwm yam txhaum.

Cov lus pom zoo: Koom nrog cov khoom siv hluav taws xob ua hluav taws xob muaj zog (xws li SVG lossis TSC) rau hauv lub cev kom nqus tau cov hluav taws xob reactive.

3. Cov khoom siv hluav taws xob thiab cov cua kub ntxhov vim muaj kev hloov pauv ntau zaus
Thaum lub sij hawm ua hauj lwm ntawm lub arc rauv, lub reactive hwj chim hloov sai heev, yuav tsum tau nquag hloov ntawm lub capacitor banks. Yog tias siv cov contactors zoo tib yam lossis cov tshuab hluav taws xob hloov pauv, qhov no tuaj yeem ua rau muaj kev cuam tshuam tam sim no thaum hloov pauv, tiv tauj yaig, thiab rov ua cua sov thiab txias ntawm lub capacitor dielectric, thaum kawg txo cov rwb thaiv tsev.

Cov lus pom zoo: Siv cov keyboards sib xyaw lossis thyristor keyboards los tswj lub capacitor hloov. Cov khoom siv no ua haujlwm ntawm qhov hluav taws xob xoom- hla cov ntsiab lus, zam kev cuam tshuam tam sim no thiab txuas ntxiv lub neej ntawm lub capacitor.
