Iyo insulation kupokana tester inogona kushandiswa kuyera kukosha kwekudzivisa kwezvinhu zvakasiyana siyana zvekushanduka kwevanochinja, motors, tambo, etc. pazasi isu tichakurukura zvimwe zvinetso zvakajairika.
01
Chii chinobuda chipfupi-dunhu riripo rwekunzwa kwezvinhu zvinoparadzanisa tester zvinoreva?
Tambo refu, motors ine mhepo dzemhepo, dzinoshandura, etcc. dzinozivikanwa seyemagetsi mitoro. Paunenge uchiyera kudzikisira kwezvinhu zvakadaro, kupfupika-dunhu riripo kwekunzwa kupokana tester kunogona kuratidza kupokana kwemukati kwekubuda kwemukati kweiyo megger yeiyo megger. .
02
Nei uchishandisa iyo yekunze "g" magumo kuyera kudzikisira kwepamusoro
Iyo "G" terminal (yekuvharidzira terminal) yeiyo kunze, basa rayo ndeyekubvisa pesvedzero yeushiviti uye tsvina munzvimbo yekuedzwa pane chiyero. Paunenge uchiyera kupokana kwepamusoro, kana ukaona kuti mhedzisiro yacho yakaoma kudzikamisa, unogona kufunga nezvekushandisa iyo g terminal kubvisa zvikanganiso.
03
Pamusoro pekuyera kupokana, nei tichifanira kuyera huwandu hwekunyora uye polarization index?
Muchiitiko cheInternational test, iyo insulation kupokana kukosha pane imwe nguva haigoni kuratidza zvakanyatsoratidza zvakanakira zvakanaka uye zvinoitika zveInsulation Basa reMuenzaniso webvunzo. Kune rimwe divi, nekuda kwezvinhu zvekusimbisa kwebasa rimwe chete, kupesana kwekunzwa kunoonekwa apo vhoriyamu kana iyo vhoriyamu yakakura, uye kupokana kwekuparadza kunoonekwa kana vhoriyamu kana iyo vhoriyamu idiki. Hombe. Kune rimwe divi, zvinyorwa zvekusimbisa zvine chirevo chekutora rutio (dar) maitiro uye polarization (pi) process mushure mekushandisa vhoriyamu yakakwira.
04
Nei magetsi ekusimbisa kwemagetsi zvinokanganisa tester kuburitsa yakakwira dc high voltage
Sekureva kwenheyo yeDC shanduko, iyo yemagetsi inosimbisa inoparadzira tester yakapihwa mabhatiri akati wandei inogadziriswa nedunhu rekuwedzera. Iyo yakaderera yemagetsi yekuisa voltage ichawedzerwa kune yakakwira yekubuda DC DC voltage. Iyo yakakwira voltage yakagadzirwa yakakwira asi simba rekubuda rakadzika.
Kuchenjera kwekushandiswa kwekushandiswa kwekuparadzira kupokana tester
1. Usati wayera, ita redunhu rakavhurika uye pfupi redunhu bvunzo pane insulation kupokana tester kuti utarise kana iyo insulation kupokana tester yakajairika. Iko kushanda kwakananga ndekwekuti: Whura waya mbiri dzekubatanidza, iyo pointer yekunyepedzera inofanirwa kunongedza kusvika mukusvika, uye ipfupi waya mbiri dzekubatanidza, iyo pointer inofanira kunongedza zero.
2. Chishandiso chiri pasi peyedzo chinofanira kubviswa kubva kune mamwe magetsi masosi. Mushure mekuyera kwapera, mudziyo uri pasi peyedzo unofanirwa kuve wakanyatsowanikwa (anenge 2 ~ maminetsi matatu) kuchengetedza michina uye kuchengetedza pachako.

4 Kana uchiedza capacitors uye tambo, zvakafanira kudzikisira wiring apo iyo crank ichibata iri kutenderera, kana zvikasadaro iyo yekudzokorora kubhadharisa ichakanganisa kupesana kupokana kupikisa tester.
5. Paunenge uchitsvedza chibatiso, chinofanira kunge chinononoka uye nekukurumidza, uye zvakanyanyisa kukurudzira kusvika kune 120r / min, uye teerera kudzivirira kuvhunduka kwemagetsi. Munguva yekutsvaira, apo pointer yasvika zero, haigone kuenderera mberi nekudziya kudzivisa nekukuvadza kune coil mune wachi.

7. Iyo yakakodzera insulation kupokana tester inofanirwa kusarudzwa zvichienderana neiyo mwero wekuvharira wemidziyo iri kuedzwa. Kazhinji, yemidziyo ine ratidziro voltage pazasi 500 volts, sarudza insulation kupesana tester ye 500 volts kana 1000 volts; Zvekushandisa neyakagadziriswa voltage ye500 volts uye pamusoro, sarudza insulation kupokana tester ye1000 kusvika 2500 volts. Mukusarudzwa kwehuremu hwenyoka, kutarisira kunofanirwa kutorwa kuti kusatorwa kuyera chiyero zvakanyanya kupfuura kusimbisa kwekukosirwa kukosha kwemidziyo mumidziyo yekuyedza kudzivirira zvikanganiso zvakawanda mukuverenga kwakakura mukuverenga.
