Vamwe vatengi, kana vachishanyira fekitori, vanosimudza mubvunzo wekuti zvigadzirwa zvemota zvinogona kudzokororwa pasi pe dielectric inomira kuedzwa kwemagetsi. Uyu mubvunzo wakabvunzwawo nevakawanda vashandisi vemotikari.Dielectric inomira voltage yekuongorora ndeye bvunzo yekuona yekuvharisa kuita kwemotor windings panguva yekugadzirwa kwekugadzira, pamwe neyese muchina chigadzirwa bvunzo. Chiyero chekutonga hunhu ndechekuti insulation haina kuputswa pasi pemamiriro akatarwa.
Kuve nechokwadi chekuti mota yekumisa mashandiro inosangana nezvinodiwa, mukuwedzera pakusarudza yakakodzera electromagnetic waya uye insulating zvinhu, yakavimbika maitiro garandi inodiwa zvakare. Semuyenzaniso, dziviriro panguva yekugadzirisa, zvigadziriso zvakakodzera, yakanaka impregnation michina, uye yakakodzera maitiro paramita.
Tichitora mamhepo emagetsi emagetsi semuenzaniso, vazhinji vanogadzira mota vanozoita kutendeuka-kune-kutendeuka uye dielectric inomira bvunzo dzemagetsi pane yega coil. Asati aiswa, musimboti une windings uye muchina wese panguva yekuongorora bvunzo uchaitwa dielectric inomira voltage kuyedzwa. Izvi zvinotidzosera kukusahadzika kwevatengi nezve dielectric standstand issue.
Nechinangwa kutaura, dielectric inomira voltage yekuyedza bvunzo isingadzoreki inoparadza. Zvingave zvema windings kana ega coil, hazvikurudzirwe kuita bvunzo dzakadzokororwa, nekukosha kwekutsvaga matambudziko senzvimbo. Muzviitiko zvakakosha apo kudzokororwa kuyedzwa kunodiwa, iyo bvunzo voltage inofanirwa kudzikiswa zvinoenderana neyakajairwa chiyero chinodiwa kuti uderedze kukuvadza kune insulation zvakanyanya sezvinobvira.
Nezve Dielectric Withstand Voltage Tester
Iyo dielectric inomira voltage tester chiridzwa chekuyera iyo dielectric inomira voltage simba. Iyo inogona intuitively, nemazvo, nekukurumidza, uye nekuvimbika kuyedza akasiyana magetsi ekuchengetedza zviratidziro senge inomira voltage, breakdown voltage, uye kuvuza ikozvino kwezvinhu zvakaedzwa. Kuburikidza neiyo dielectric inomira voltage tester, matambudziko anogona kuwanikwa uye kutevedza kwekuita kwe insulation kunogona kutsanangurwa.
● Ziva kugona kwekudzivirira kushingirira kushanda kwevoltage kana kuti overvoltage.
● Tarisa kunaka kwekugadzira insulation kana kuchengetedza midziyo yemagetsi.
● Bvisa kukuvadzwa kwekuvharisa kunokonzerwa nemidziyo, kugadzirisa, kana kutakurwa, uye kuderedza kukurumidza kutadza kwechigadzirwa.
● Ongorora kutevedza kwemagetsi emagetsi uye creepage kureba kwekudzivirira.
Nheyo dzeKusarudza Dielectric Inomira Voltage Test Voltage
Iyo yakanakisa nzira yekuona iyo test voltage ndeyekuimisa zvinoenderana nezvinodiwa pabvunzo. Kazhinji, magetsi ekuedzwa anoiswa pa 2 times the rated voltage plus 1000V. Semuenzaniso, kana chigadzirwa chine rated voltage ye380V, test voltage inenge iri 2 x 380 + 1000 = 1760V. Ehe, iyo bvunzo voltage inogonawo kusiyana zvichienderana nekirasi yekuisa uye akasiyana echigadzirwa ane akasiyana voltage zvinodiwa.
Sei zvakakosha kugara uchitarisa kutendeseka kweyedzo yedunhu?
Dielectric instand voltage testers pamutsara wekugadzira inoshandiswa kazhinji, kunyanya iyo inotungamira bvunzo uye zvigadziriso zvekuyedza izvo zvinowanzo famba, zvichiita kuti vatarise mukati mepakati waya kuputswa uye maseketi akavhurika, ayo asingawanzo kuve nyore kuona. Kana paine dunhu rakavhurika pane chero nzvimbo muchiuno, iyo yakakwira voltage inobuda nedielectric inomira voltage tester haigone kuiswa kune chinhu chakaedzwa. Izvi zvikonzero zvinogona kukonzera iyo yakakwira voltage kuti isanyatso shandiswa kuchinhu chakayedzwa panguva yedielectric inomira kuedzwa kwesimba, uye nemasikirwo, iyo yazvino inoyerera nechinhu chakaedzwa ingangoita zero. Sezvo isingapfuure muganho wepamusoro wakatemerwa neiyo dielectric inomira voltage tester, chiridzwa chinopa kukurumidza kuti bvunzo yacho inokodzera, uchifunga kuti insulation inokodzera. Nekudaro, iyo data yekuyedza mune iyi kesi haisi yechokwadi. Kana chinhu chakayedzwa chikaitika chine hurema hwekudzivirira panguva ino, zvinotungamira mukusanzwisisa kwakakomba.
