Winding resistance test yakakosha pakuongorora kutendeseka kwetransformer windings.Nekuyera maitiro ekupikisa, zvikwata zvekuchengetedza zvinogona kuongorora kuenderera kwemagetsi uye kuona chero zvisizvo zvinogona kutungamirira mukupisa kana kusashanda zvakanaka.

Megger Test

Iyo Megger bvunzo, inozivikanwawo seye insulation yekudzivirira yekuyedza, inoongorora iyo insulation zvimiro zve transformer windings.Muedzo uyu unobatsira mukuona chero kuparara kwekudzivirira kana kubuda kwemhepo kunogona kukanganisa kuchengetedza uye kuita kweshanduko.

Transformer inoshandura mwero

Transformer inoshandura reshiyo yekuyedza inosimbisa reshiyo yekutendeuka pakati pepuraimari nesekondari mamhepo.Misiyano pakuchinjana reshiyo inogona kuratidza kukanganisa senge kupfupika kutendeuka kana kumonereka deformation, kuratidza nzvimbo dzinoda kutariswa nekukurumidza.

• Ita shuwa nzvimbo yakakodzera pakati pematransformer ekufemesa.
• Kuiswa kwemukati kunofanirwa kubvumira kupinda nyore kwemabasa ekugadzirisa.

 

Operation Guidelines

Kushanda kwakanaka kwetransformer kunoenderana nekuteedzera kwakasimba kune mirairo yekushanda inoisa pamberi pekuchengetedza uye kuita.Kutarisa uye kudzora akakosha ma paramita akadai se impedance voltage uye simba chinhu chakakosha kuchengetedza mashandiro akagadzikana pasi pemitoro yakasiyana.

• Monitor impedance voltage nguva dzose panguva yekushanda.
• Chengetedza simba rakagadzikana kuti uwedzere kushanda kwesimba.
• ShandisaNEMAICS zviyero zvekushanda kwakachengeteka uye kwakavimbika.

Monitoring uye Kudzora

Kuongorora maparamendi etransformer kwakakosha kufungidzira zvingangoitika zvinogona kutungamira mukukundikana kana kusashanda.Kugara uchiongorora mazinga anonzwika anogona kuratidza kusagadzikana mukushanda, zvichikurudzira kupindira panguva yakakodzera kudzivirira imwe kukuvara.

"Kugara uchitarisisa mazinga anonzwika anonzwika kunoita kuti aonekwe nekukurumidza kwezvisina kurongeka."

Emergency Procedus

Kugadzira nzira dzakajeka dzekukurumidzira kwakakosha mukudzikamisa njodzi panguva yezviitiko zvisingafanoonekwi.Kuve nemaprotocol munzvimbo yemamiriro akaita semagetsi akangoerekana akwira kana kusashanda zvakanaka kwemidziyo kunosimudzira matanho ekuchengetedza mukati menzvimbo, kudzivirira vashandi uye zvinhu kubva mukukuvadzwa.

"Maitirwo echimbichimbi akatsanangurwa anogonesa mhinduro nekukurumidza panguva dzakaoma, kuderedza nguva yekuzorora uye kuve nechokwadi chekuchengetedzwa kwevashandi."
