Ngaba ukupeyinta ngesitshizi kunokusombulula ingxaki yokujikeleza okufutshane phakathi kokujika kwee-motor windings?

I-inter-turn short circuit yimpazamo yombane enokwenzeka ngexesha lokuveliswa, ukucutshungulwa kunye nokusetyenziswa kwayo nayiphi naimotoUkujika. Xa kwenzeka impazamo ye-inter-turn short circuit, ingaba ingalungiswa kwaye ngawaphi amanyathelo ekufuneka athathwe?

Ukujijela kunye nokufakelwa kwee-motor windings kunokuba nemiphumo emibi kumaleko wokugquma kwee-electromagnetic wire. Nokuba yi-enamel electromagnetic wire okanye i-mica wire wrapped wire esetyenziswa ekwenzeni ii-windings, kunzima ukuziphepha iingxaki ezinjalo. Inkqubo yokubumba i-molded winding nayo inempembelelo enkulu kumgangatho we-electromagnetic wire insulation maleko. Xa i-mold ingafanelekanga kwaye uyilo lwe-winding shape lungafanelekanga, luya kukhokelela kwiingxaki ezinkulu zomonakalo we-insulation ngexesha lenkqubo yokubumba, nto leyo enokuba yingozi esemgangathweni kwiingxaki ze-inter-turn short circuit.

Xa kuvela iingxaki ezifanayo kwi-winding ngaphambi kokuba kufakwe ipeyinti, amanyathelo okulungisa i-insulation afunekayo anokuthathwa ukuze kwahlulwe kwaye kukhuselwe iingcingo ze-electromagnetic ezonakeleyo; ngexesha lenkqubo yonyango lwe-insulation ye-winding, ipeyinti ye-insulation inokudlala indima ethile ekuqiniseni i-insulation phakathi kokujika. Kuyavela ukuba ukusebenza kwe-insulation ye-electromagnetic wire eyonakeleyo kunokuhlangabezana ngokupheleleyo neemfuno ze-insulation ze-motor; nangona kunjalo, ukuba isiphumo se-insulation asibonakali kakuhle, ngokuqinisekileyo siya kukhokelela ekusileleni komgangatho wombane ngexesha lokusebenza kwe-motor, oko kukuthi, iingxaki ze-inter-turn short circuit ngexesha lokusebenza.

Xa kuthelekiswa, ingxaki ye-inter-turn short circuit eyenzeka kwi-winding ngaphambi kokuba imoto isebenze ifunyanwa kakhulu nge-inter-turn insulation tester, kwaye kusekho ithuba lokuthatha amanyathelo asebenzayo okulungisa; xa i-winding short circuit isenzeka ngexesha lovavanyo olupheleleyo lomatshini okanye ukusebenza kwe-motor ukungasebenzi kakuhle kwaye akukho thuba lokulungiswa.

Xa kwenzeka impazamo yesekethe emfutshane phakathi kwe-turn ngexesha lokusebenza kwemoto, impazamo ibonakala njengengxaki ye-insulation ye-multi-turn, kwaye ezinye zichaphazela ne-coil yonke. Iziphumo ezibi kakhulu ziya kuba kwi-insulation ye-phase-to-phase kunye ne-ground insulation. Oko kukuthi, impazamo yesekethe emfutshane phakathi kwe-inter-turn ineziphumo ezinkulu ze-derivative, kwaye inqanaba le-inter-turn fault liya kuba libi ngakumbi. Umaleko we-insulation we-electromagnetic wire phantse ukwimeko yokuqhekeka, ngoko ke yonke i-winding kufuneka itshintshwe.

Ke ngoko, abavelisi abaninzi beemoto banikela ingqalelo enkulu kwitekhnoloji yokucubungula ii-winding, bazama konke okusemandleni abo ukunciphisa nokususa iingozi ezifihlakeleyo zeziphene zokufakelwa kwe-insulation, kwaye ngokusisiseko baphucule umgangatho wokusebenza kombane wemoto.
