Tsis Siv Neeg CVT Capacitance Thiab Tan Delta Meter

I. Txheej txheem cej luam

Tsis Siv Neeg Capacitance thiab Tan Delta Test Set yog ib hom kev ntsuas nrog siab precision siab tsis siv neeg ntsuas lub dielectric poob tangent thiab capacitance ntawm ntau yam high voltage hluav taws xob equipments nyob rau hauv lub fais fab nroj tsuag thiab substations. Kev siv cov tshuab hloov pauv zaus tuaj yeem ua kom ntsuas qhov tseeb hauv kev cuam tshuam ntawm cov hluav taws xob muaj zog.

Kev qhia ua haujlwm ntawm cov cuab yeej yog Suav. Tag nrho cov txheej txheem yog ntsuas tau los ntawm microcomputer.

Qhov ntsuas kuj tseem siv tau rau kev ntsuas ntawm tgδ thiab lub peev xwm hluav taws xob ntawm cov khoom siv hluav taws xob hluav taws xob siab hauv cov chaw ua haujlwm, cov chaw soj nstuam thiab cov chaw tshawb fawb.

Nws tuaj yeem ntsuas cov khoom siv hluav taws xob tsis muaj av lossis hauv av uas siv cov khoom siv hluav taws xob zoo thiab tsis zoo. Dhau li ntawd, nws tuaj yeem ntsuas qhov tgδ ntawm capacitor voltage transformer thiab capacitance ntawm lub ntsiab capacitor C1 thiab C2.

Qhov ntsuas yog nruab nrog high voltage step-up transformer. Tsis tas li ntawd, nws yuav siv kev ntsuas kev ruaj ntseg xws li xoom-cross kaw, tiv thaiv xob laim, thiab lwm yam. Thaum lub sijhawm sim, qhov sib txawv ntawm cov hluav taws xob sib txawv ntawm 0.5KV txog 10kV yog outputted. Cov cuab yeej muaj qhov zoo ntawm kev ua haujlwm yooj yim thiab nyab xeeb.

Raws li qhov tshwm sim ntawm cov roj dielectric poob ≥ 0.01%, nrog lub khob roj, cov xaim zoo tuaj yeem siv los ntsuas cov roj dielectric poob.

Cov yam ntxwv tiv thaiv hauv qab no tsis suav nrog hauv qhov ntsuas no:

• High voltage tiv thaiv luv luv

• CVT tiv thaiv dhau-voltage

• Kev tiv thaiv hauv av tsis zoo
