Kudzivirira kwekudzivirira kwemota ndiyo yakakosha paramende yekuongorora mashandiro ayo ekudzivirira, ayo ane hukama zvakananga nekushanda kwakachengeteka kwemota. Nekuda kwemhando dzakasiyana uye mazinga emagetsi emotor, iwo mashoma zviyero zvekupokana kwekudzivirira zvakare akasiyana.
Insulation resistance ye low-voltage motors
For low-voltage motors ine voltage mazinga e400V uye pazasi, iwo mashoma mwero wekupokana kwekudzivirira ndeaya anotevera:
Mitsetse ichangobva kuiswa: Kudzivirira kwekudzivirira pakati pemitsara uye pakati pemitsara nepasi hakufanirwe kunge iri pasi pe0.5 megohms.
Zvishandiso uye mitsetse iri kushanda: Kudzivirira kwekudzivirira hakufanirwe kunge kuri pasi pe1 megohm/kilovolt, kana kuenzana ne1 kiloohm/volt.
Insulation kuramba kwemadiki uye epakati-saizi mota
Kune akajairwa madiki uye epakati-saizi mota, iyo yakaderera mwero wekupokana kwekudzivirira zvakare haisi pasi pe 0.5 megohms. Iyi chiyero inoshanda kumidziyo uye mitsetse iri kushanda, uye kudzivirira kwekudzivirira hakufanirwe kunge kuri pasi pe1MΩ/kV.
Insulation resistance yehigh-voltage yemagetsi motas
Izvo zvinodzivirira zvekudzivirira zvinodikanwa zveakakwira-voltage motors zvakanyanya kuomarara. Iwo chaiwo mazinga ndeaya anotevera:
Stator insulation resistance: Pakushanda tembiricha, kudzivirira kwekudzivirira hakufanirwe kunge kuri pasi pe1 megohm pa kilovolti.
Rotor insulation resistance: Kudzivirira kwayo kwekudzivirira hakufaniri kuva pasi pe 0.5 megohms pa kilovolt.
Kuyerwa kwemotor insulation resistance
Paunenge uchiyera chaizvo kudzivirira kwekudzivirira kwemota, panogona kunge paine mimwe misiyano nekuda kwekunongedza zviyero zvakasiyana uye pesvedzero yezvinhu zvakaita seye tembiricha uye kunyura. Kunyanya kana iyo insulation resistance value uye absorption ratio iri padyo nekukosha kwakakosha, mhinduro dzebvunzo dzevashandisi vakasiyana dzinogona kunge dzakasiyana. Nokudaro, pakuyera, mitemo yakakodzera inofanira kuteverwa zvakasimba, chiridzwa chakakodzera chinofanira kusarudzwa, uye zvakasiyana-siyana zvinodiwa zvekutonhora uye zvinopisa zvinofanira kusiyaniswa.
Muchidimbu, iyo yakaderera insulation yekudzivirira chiyero chemotor zvinoenderana neiyo voltage level uye mhando. Kudzivirira kwekudzivirira kweakadzika-voltage motors uye madiki uye epakati-saizi mota /yepakati voltage induction mota inowanzodiwa kuti ive isingasviki 0.5 megohms, nepo kudzivirira kwekudzivirira kwemagetsi emagetsi epamusoro hakufanirwe kunge ari pasi pe1 megohm pa kilovolti. Aya mazinga anoitirwa kuti ive nechokwadi chekuti mota haizokonzeresa tsaona dzekuchengetedza nekuda kwekusakwana kuvharirwa panguva yekushanda.
