Iyo insulation material yemota inotarwa nehukuru hweizvino kana voltage?

Ndiyo insulationzvinhuyemota inotarwa nehukuru hweazvino kana kuti voltage?

Insulation zvinhuchinhu chakakosha chakakosha chezvigadzirwa zvemotokari. Mota dzine mazinga akasiyana emagetsi ane misiyano mikuru muchimiro chekudzivirira chemhepo dzadzo uye zvikamu zvadzo zvakakosha. Semuenzaniso, iyo insulation chimiro cheyakakwira-voltage mota uye yakaderera-voltage mota windings yakasiyana zvakanyanya. .

Insulating zvinhu, inozivikanwawo se dielectrics, zvinhu zvine yakakwira resistivity uye yakashata kwazvo conductivity. Izvo zvinoshandiswawo muzvigadzirwa zvemotokari nekuda kwekusaita kwavo conductivity. Muzvigadzirwa zvemotokari, kuburikidza nekudzivirira zvinhu, kune rumwe rutivi, waya dzinofambisa dzakabatanidzwa nezvimwe zvikamu. Kupatsanura, kune rumwe rutivi, ndiko kuparadzanisa mapoinzi akasiyana emutsetse wekuitisa, senge inter-turn insulation uye inter-phase insulation. Yakasiyana insulating zvinhu zvinogona zvakare kuve nemhando dzakasiyana siyana senge tsigiro, gadziriso, arc kudzimisa, mildew resistance, radiation protection uye corrosion resistance.

Kupisa kwemota windings chiratidzo chekongiri chekuora kana kunyangarika kwekuita kwekudzivirira. Zvadaro, iko kushanda kwekudzivirira kwemota kwakadzikira nekuda kwemhepo huru yekumonereka kana kuti yakakwira voltage?

Kana iyo mota inotenderedza yazvino yakawandisa, iyo yakakwira density iripo inokonzeresa kuramba kwemhepo kuwedzera uye kukonzera kupisa kwakanyanya. Kupisa kunogadzirwa nemotor kuchabviswa kuburikidza nekudzivirira. Kana kupisa kwasvika pane imwe nhanho, chimiro cheiyo insulating zvinhu chichaita shanduko yemhando, senge mota Izvo zvinodikanwa zvekushanda kwemagiredhi akasiyana ekudzivirira akadai seB, F, uye H anosanganisirwa mutafura anoenderana nehupamhi hwekushanda tembiricha iyoinsulating zvinhuinogona kumira.

Kune iyo mota inotenderera, izvo zvinodiwa zvekudzivirira pakati pekutendeuka nekutendeuka, pakati pezvikamu zvakasiyana zveakawanda-chikamu mota, uye pakati pe conductor nepasi zvinobatanidzwa. Kana iyo yakayerwa voltage yemota yakakwira, iyo voltage yemhepo yekuvharisa inokwira zvakare, inogona kunge iri nyore Funga nezveizvi seakasiyana capacitors. Kana iyo voltage pakati peiyo capacitors yakanyanya kukwira, inotungamira kune dambudziko rekuputsika kwecapacitor, ndiko kuti, kutadza kwekudzivirira kwemota inotenderera pasi, pakati pekutendeuka uye pakati pezvikamu.

Kubva pane zviri pamusoro, tinogona kunzwisisa kuti kunyangwe iyo yazvino yemota yakakwira-voltage iri diki, iyo insulation voltage yemhepo yakakwira, saka yakakosha yekumisa chimiro inofanirwa kushandiswa kuve nechokwadi chekuti mashandiro emagetsi emota anosangana nezvinodiwa. ; nepo iyo yakaderera-voltage mota, nekuti iyo insulation voltage yakakwira saka, kusarudzwa kwezvinhu zvinodzivirira zviri nyore, asi ikozvino density, kufefetedza uye kupisa kupisa ndizvo zvinhu zvakakosha kuti ive nechokwadi chekushanda kwemagetsi emota. Iyo yazvino uye voltage yemota ine maitiro akasiyana paneinsulating zvinhuuye inofanira kurangarirwa panguva imwe chete.
