Iyo insulation resistance tester inonyanya kushandiswa kuyera kudzivirira kwekudzivirira kwema transformer mahombe, transformer, jenareta, high-voltage motors, magetsi capacitors, tambo dzemagetsi, zvinosunga uye zvimwe zvishandiso.
GD3127/3128 Insulation Resistance Tester
Kushanda uye kuyedza matanho eiyo insulation resistance tester:
(1) Iyo shaker inofanirwa kusarudzwa zvinoenderana neiyo voltage level yemidziyo.Kune vashanduri ve10KV-35KV, 2500 volt shaker inofanira kushandiswa.
(2) Usati wayera kudzivirira kwekudzivirira, magetsi emidziyo iri pasi pekuyedzwa anofanirwa kudimburwa, uye Ita kuburitsa kwepfupi-kutenderera, chinangwa chekuburitsa ndechekuchengetedza kuchengetedzwa kwevanhu nemidziyo, uye kuita kuyerwa. migumisiro yakarurama;
(3) Kubatana kweiyo shaker kunofanirwa kunge kune maviri akaparadzana waya (mavara maviri) ane yakanaka insulation, maviri Usamonyanisa waya dzinobatanidza pamwe chete, uye usaite kuti waya dzinobatanidza dzibatane pasi, kuitira kudzivirira kukanganisa kunokonzerwa nehurombo. kuvharidzira kwetambo dzekubatanidza;
(4) Usati wayera, ita rakavhurika redunhu uye pfupi dunhu bvunzo pane shaker kuti uone kana shaker iri mumamiriro akanaka uye transformer yakavharwa.Kana muyedzeri wekupikisa akavhura mitsara miviri yekubatanidza uye achizunza mubato, chinongedzo chinofanira kunongedza pa ∞ (infinity).Panguva ino, kana mitsara miviri yekubatanidza ipfupi-yakatenderedzwa, chinongedzo chinofanira kunongedza pa0, zvinoreva kuti shaker iri mumamiriro akanaka., kana zvisina kudaro pane kukanganisa mutafura inodedera;
(5) Iyo wiring nzira yekuzunungusa kudzivirira kwekudzivirira kweyekutanga mhepo kune yechipiri mhepo uye pasi (shell): Ipfupi-inotenderera iyo-nhatu-chikamu terminals lU, lV uye 1W yekutanga mhepo ine waya isina mhangura, kuitira kubatanidza kune "L" kuguma kwemegohmmeter;pfupi-dunhu materminals N, 2U, 2V, 2W uye pasi (yepasi crust) yechipiri mhepo inotenderera ine isina mhangura waya dzemhangura, uye wozozvibatanidza kune "E" kumagumo megohmmeter;kana zvichidikanwa, kuti uderedze pesvedzero yekudonha kwepasi pane yakayerwa kukosha, iyo isina tambo yemhangura inogona kukuvadzwa pane porcelain siketi yepakutanga side porcelain sleeve kwemajana mashoma, uye yobva yabatanidzwa kune "G" kumagumo kwe. megohmmeter ine insulated waya;
(6) Kuzunungusa kuyerwa kweyechipiri inomonereka peya Iyo nzira yewaya yekudzivirira kwekudzivirira kwekutanga mhepo uye pasi (shell): pfupi-circuit iyo 2U, 2V, 2W, uye N zviteshi zvechipiri chinomonereka netambo dzemhangura dzisina chinhu. .Kuti ubatanidze kumagumo e "L" megohmmeter;mushure mekupfupika-kutenderera kwechikamu chetatu-chikamu chinotungamira 1U, 1V, 1W uye pasi (shell) yekutanga mhepo ine waya isina mhangura yemhangura, vabatanidze kune "E" kuguma kwe megger;Kuti uderedze pesvedzero yekudonha kwepamusoro pachiyero chakayerwa, waya yemhangura isina chinhu inogona kukuvadzwa yakatenderedza siketi yeporcelain yechikamu chechipiri cheporcelain sleeve kwemajana mashoma, uye yozobatanidzwa kune "G" kumagumo kwemegohmmeter newaya yakavharidzirwa. .
(7) Pakuyera, dzvanya goko remusheki neruoko rumwe (kudzivirira kuti shaker irege kudedera).Kana iyo pointer ichiratidza 0, rega kuzunungusa nekukasira kudzivirira kupisa wachi;
(8) Pakuyera, isa tafura inozunguzika panzvimbo yakachinjika, shandura mubato unozunguza wejenareta nekumhanya kunosvika 120 revolutions paminiti, uye verenga pa15s Tora nhamba (R15), verenga imwe nhamba (R60) pa. 60s, uye rekodha iyo inodedera data.
