Mimwe midziyo yekuyeresa yekumisa pasi inoda kubviswa pakuyera, nepo vamwe vasingadaro, zvakanyanya nekuda kwezvinotevera kufunga.Kana vasina kubviswa, zvinotevera zvinoitika:
HV Hipot GDCR3200C yakapetwa kaviri mbambo yakawanda-inoshanda pasi pekupikisa tester
1. Kana iyo yekumisikidza yekumisa electrode iri pasi pekuyedzwa yakakura kwazvo kana waya yakaputsika pasi pevhu, ikozvino sosi kana jenareta mune yekuyeresa chiridzwa ichavhurika, uye ipapo iyo yakavhurika yedunhu voltage ichaitwa kune casing yechiridzwa chemukati. uye midziyo kuburikidza nemukati grounding system.Iyo yakavhurika-circuit voltage yejenareta-yakarembedzwa nemaoko kazhinji iri pamusoro pe100V, uye yakavhurika-yedunhu voltage yebhatiri-powered ikozvino sosi kazhinji iri pasi pe50V.
2. Kana midziyo yemagetsi yemukati ichidonha ikozvino, ikozvino ichaiswa jekiseni kubva kune yakaedzwa electrode kusvika pasi, uye kudonha kwemagetsi kuchagadzirwa panzvimbo yakapoteredza, iyo inonzi voltage yepasi.Kana simba revhu riri diki, rinokanganisa mhedzisiro yekuyera, uye kana iyo voltage yepasi yakakura, inotyisidzira kuchengetedzwa kwevashandi kana kukuvadza kupikisa kwepasi.pamusoro.
3. Dzimwe nzira dzisiri dzepasi pasi dzinobatanidza maviri ekutanga akazvimiririra pasi pasi kuburikidza necasing yechiridzwa uye midziyo.Ukoshi hwekupikisa hwakayerwa nemamita ekumisa pasi haisi imwe yekumisa pasi, asi kubatana kwakafanana kwemaviri system grounding resistances.Kunyange kana electrode yepasi pasi pekuedzwa yakaputsika, haigoni kuonekwa.
Zviri nani kubvisa tambo yepasi paunenge uchiyera kupikisa kwepasi.Kana zvisiri, teerera kudzivirira mamiriro ari pamusoro, uye ita:
(1) Tanga nepima voltage yepasi.Kana iyo voltage yepasi yemapoinzi E uye C yakakura kupfuura zvinodiwa zvechiyereso, dzima midziyo yemagetsi yakakodzera, uye dzima simba kana zvichidikanwa.
(2) Tarisa uye simbisa kuti electrode iri pasi pekuedzwa yakanyatsodzika, tarisa kubatana kweaya maviri akazvimirira epasi masisitimu, uye usasanganisire irregular grounding point.Mazuva ano, iyo yepasi pasi inowanzodikanwa kugovera pasi electrode, saka hapana maviri akazvimirira pasi emagetsi emagetsi, uye mamiriro ekunze ekubatanidza haatariswe.Kuti utarise waya dzakaputsika, pima kupikisa kwe loop.
