Imbaraga za dielectric (kwihanganira voltage) ikizamini

Ikizamini cyingufu zamashanyarazi, kizwi cyane nka stand ya voltage test, ni igipimo cyubushobozi bwumuriro wamashanyarazi kugirango uhangane no gusenyuka bitewe nigikorwa cya overvoltage.Nuburyo bwizewe bwo gusuzuma niba ibicuruzwa bifite umutekano gukoresha.

Hariho ubwoko bubiri bwimbaraga zamashanyarazi: imwe ni DC ihanganira ikizamini cya voltage, naho ubundi ni AC power frequency kwihanganira ikizamini cya voltage.Ibikoresho byo murugo byo murugo bikorerwa AC power frequency kwihanganira ikizamini cya voltage.Ibice byageragejwe hamwe nigipimo cya voltage indangagaciro zumuriro wamashanyarazi zirasobanuwe kandi zisobanuwe muri buri gipimo cyibicuruzwa.

Niyihe ntego yo gupima ubukana bwibikoresho byamashanyarazi?

Ibintu bigira ingaruka ku gipimo cyapimwe cyo kurwanya insulasiyo ni: ubushyuhe, ubushuhe, voltage yo gupima nigihe cyibikorwa, amafaranga asigara mumuzunguruko hamwe nubuso bwimiterere ya insulasiyo, nibindi. Mugupima ubukana bwibikoresho byamashanyarazi, intego zikurikira zirashobora kugerwaho:

a.Sobanukirwa nuburyo bwo kubika ibintu.Imiterere ishyira mu gaciro (cyangwa sisitemu yo kubika) igizwe nibikoresho byujuje ubuziranenge bigomba kuba bifite imiterere myiza yo gukumira no kurwanya izirinda cyane;

b.Sobanukirwa n'ubwiza bwo kuvura ibicuruzwa biva mu mashanyarazi.Niba kuvura insulasiyo yibicuruzwa byamashanyarazi atari byiza, imikorere ya insulation izagabanuka cyane;

c.Sobanukirwa n'umwanda hamwe n'umwanda wanduye.Iyo kubika ibikoresho byamashanyarazi bitose kandi byanduye, ubusanzwe irwanya insulasiyo izagabanuka cyane;

d.Reba niba insulasiyo ihanganira ikizamini cya voltage.Niba ikizamini cyo guhangana na voltage gikozwe mugihe irwanya insulasiyo yibikoresho byamashanyarazi biri munsi yumupaka runaka, hazabaho ingufu nini yikizamini, bikaviramo gusenyuka kwumuriro no kwangirika kwizuba ryibikoresho byamashanyarazi.Kubwibyo, ibipimo ngenderwaho bitandukanye mubisanzwe bivuga ko kurwanya insulasiyo bigomba gupimwa mbere yikizamini cya voltage.

Imbaraga za dielectric (kwihanganira voltage):

Urukurikirane rwa RK267, RK7100, RK9910, RK9920 rukurikirana ibizamini bya voltage (imbaraga za dielectric) bihuye na GB4706.1, ukurikije icyiciro kiriho ubu bigabanijwemo AC na AC hamwe na DC ibyiciro bibiri, ibyiciro bibiri, ukurikije urugero rwa voltage isohoka nka 0-15kV ihangane na tester ya voltage Kandi ubwoko bubiri bwa ultra-high voltage ihanganira ibizamini bya voltage hejuru ya 20kV.Ibisohoka voltage intera ni 0-100kV, kandi ibisohoka ntarengwa bishobora kugera kuri 500mA.Nyamuneka ohereza ku bicuruzwa hagati y'ibipimo byihariye.

Ibisabwa byo kurwanya ibikoresho byo murugo ntabwo biri hejuru, kandi 5kV irashobora kuzuza ibisabwa kugirango ibizamini bya voltage bikenerwa mubikoresho byinshi byo murugo.RK2670AM, RK2671AM / BM / CM RK2671DMni ubwoko bugezweho (AC na DC 10KV, 100ma y'ubu),RK2672AM / BM / CM / DM / E / EM、RK2674A / B / C / -50 / -100nubundi buryo bwo kwihanganira ibipimo bya voltage.

Muri byo RK267 harimo guhindura intoki,RK71, RK99urukurikirane rushobora kumenya kwikora, imikorere yitumanaho.
