Maitiro ekusarudza iyo yakakodzera renji kune inomira voltage tester?

1. Kushingirira test voltage, inowanzozivikanwa se "high voltage dielectric test", inonzi "withstand voltage test".Murau wakakosha wekusarudza iyo yakakodzera siyana yevoltage inomira tester ndeye kushandisa voltage yekushanda kaviri yechinhu chinoyedzwa, wobva wawedzera chiuru chevolts seyevoltage chiyero chebvunzo.Iyo yekuyedza voltage yezvimwe zvigadzirwa inogona kunge yakakwira kupfuura 2 × Iyo yekushanda voltage iri + 1000V.Semuyenzaniso, simba remagetsi rinoshanda rezvimwe zvigadzirwa rinobva pa100V kusvika pa240V, uye magetsi ekuyedza ezvigadzirwa zvakadaro anogona kunge ari pakati pe1000V ne4000V kana kupfuura.Kazhinji, zvigadzirwa zvine "double insulation" dhizaini inogona kushandisa bvunzo voltage yakakwira kupfuura 2 × Kushanda voltage + 1000V yakajairwa.

2.The standstand voltage test yakanyatsojeka mukugadzirwa kwechigadzirwa uye sampuli kugadzira pane kugadzirwa kwepamutemo, nekuti kuchengetedzwa kwechigadzirwa kwakatemwa mukugadzira uye nhanho yekuyedza.Kunyangwe masampula mashoma achishandiswa kutonga dhizaini yechigadzirwa, bvunzo dzepamhepo panguva yekugadzira dzinofanirwa kuve dzakaomarara.Zvese zvigadzirwa zvinofanirwa kupfuudza zviyero zvekuchengetedza, uye zvinogona kusimbiswa kuti hapana chakaremara zvigadzirwa zvichayerera zvichibuda mumutsara wekugadzira.

3.Kubuda kwemagetsi ekudzivirira voltage tester kunofanirwa kuchengetwa muhuwandu hwe100% kusvika ku120% yemhepo yakataurwa.Iyo inobuda frequency ye AC inomira voltage tester inofanirwa kuchengetedzwa pakati pe40Hz uye 70Hz, uye kukosha kwayo kwepamusoro hakuzodzike kupfuura 1.3 nguva yemudzi we mean square (RMS) voltage value, uye kukosha kwayo kwepamusoro hakuzokwire kupfuura 1.5 times. yemudzi we mean square (RMS) voltage value.

4.Different zvigadzirwa zvine maitiro akasiyana ehunyanzvi.Chaizvoizvo, mukumira kwevoltage test, voltage yakakwira kupfuura yakajairika kushanda voltage inoiswa kuchigadzirwa kuti chiedzwe.Iyo voltage inofanirwa kugara kwenguva yakatarwa.Kana iyo yekudonha ikozvino yechikamu ichichengetwa mukati meiyo yakatarwa mukati menguva yakatarwa, inogona kutariswa kuti chikamu chakachengeteka kwazvo kushanda pasi pemamiriro akajairika.Yakanakisa dhizaini uye kusarudzwa kwezvinhu zvakanaka zvekudzivirira zvinogona kudzivirira mushandisi kubva netsaona yemagetsi kuvhunduka
