Ukuguqulwa kwesekethe emfutshane yimpazamo yombane enokuthi yenzeke ngexesha lokuveliswa, ukulungisa kunye nokusetyenziswa kwayo nayiphi naimotoumoya. Xa kuvela impazamo yesiphaluka esifutshane esifutshane, ngaba kunokulungiswa kwaye manyathelo mani athathwe?
Umoya ovuthuzayo kunye nokuxhonywa kweemoto zinokuba neziphumo ezibi kwi-inshurensi yeengcingo ze-elektromagneticic. Nokuba yi-enctromagnetic wire okanye i-mica wire wire icingo elisetyenzisiweyo ekwakheni imimoya, kunzima ukuthintela ezo ngxaki. Inkqubo yokuxhuzula yomthombo wobunjineli ineempembelelo ezintle kumgangatho we-elektromagnetic wire. When the mold is inappropriate and the winding shape design is unreasonable, it will lead to serious insulation damage problems during the molding process, which is a potential quality hazard for inter-turn short circuit problems.
When similar problems occur in the winding before dipping in paint, necessary insulation remedial measures can be taken to isolate and protect the damaged electromagnetic wires; Ngexesha lenkqubo yonyango yokufakelwa, ukufaka ipeyinti kunokudlala indima ethile ekomelezeni i-insumpases phakathi ukujika. It turns out that The insulation performance of the injured electromagnetic wire may fully meet the insulation performance requirements of the motor; however, if the insulation effect is not very obvious, it will inevitably lead to electrical quality failures during the operation of the motor, that is, inter-turn short circuit problems during operation.
In comparison, the inter-turn short circuit problem that occurs in the winding before the motor is running is mostly discovered through the inter-turn insulation tester, and there is still an opportunity to take some effective remedial measures; Xa isekethe emfutshane yomoya yenzeka ngexesha lovavanyo olupheleleyo lomatshini okanye ukusebenza ngokungasebenzi kakuhle kwemoto kunye nokulungiswa okuncinci kokulungiswa.
When an inter-turn short circuit fault occurs during the operation of the motor, the fault is manifested as a multi-turn insulation problem, and some even affect the entire coil. Iziphumo ezibi ngakumbi ziya kuba kwimeko yokufakelwa kwesigaba senqanaba lesigaba kunye nokufakwa komhlaba. Oko kukuthi, igalelo lesiphatho sesekethe esifutshane esifutshane lineziphumo ezikhulu eziphezulu, kwaye inqanaba letyala lokujika liza kulunga kakhulu. Ufakelo lwe-inshurensi lwe-electromagnetic ucingo luphantse kukwimeko ephembelayo, ke wonke umthombo womoya kufuneka utshintshwe.
