Product Description

Lub capacitor tiv thaiv yog txuas nrog nyob rau hauv parallel nrog lub tshuab nqus tsev hloov.Thaum lub tshuab nqus tsev hloov mus rau qhov inductive load, nws tuaj yeem tsis tsuas yog txwv kev khiav hauj lwm overvoltage mus rau ib qho chaw, tab sis kuj ncua lub sij hawm sawv ntawm qhov kev txiav tawm overvoltage thiab rov ignition overvoltage yoj lub taub hau thiab txo qhov steepness, yog li ntawd. tiv thaiv cov khoom siv hluav taws xob yog rwb thaiv tsev los ntawm kev cuam tshuam ntawm cov yoj yoj pem hauv ntej.
Nws yog siv nyob rau hauv 50Hz, 3kV, 6kV, 10kV, 35kV fais fab tshuab los tsim ib tug kuj-capacitance absorber nrog ib tug resistor.Nws siv lub zog absorbed los ntawm lub capacitor los txo qhov voltage amplitude thiab damping nyhuv ntawm tus resistor kom attenuate oscillation thiab tiv thaiv overvoltage.Hom av ntawm qhov nruab nrab ntawm qhov taw tes yog txwv kom ntseeg tau tias nws phim cov rwb thaiv tsev theem ntawm lub cev muaj zog thiab txhim kho cov khoom siv hluav taws xob zoo ntawm daim phiaj hluav taws xob.
Hauv lwm lub sijhawm, nws kuj tuaj yeem siv los ua lub tshuab hluav taws xob siab.Thaum txuas ntawm cov kab thiab hauv av, nws tuaj yeem txo qis atmospheric overvoltage, wavefront steepness thiab ncov-rau-peak tus nqi.
Nws tuaj yeem tiv thaiv cov khoom siv hluav taws xob thaum siv nrog tus ntes;Nws yog qhov sib txuam capacitor rau RC overvoltage absorption ntaus ntawv ntawm lub tshuab nqus tsev Circuit Court breaker.
