(1) Isiphaluka esifutshane phakathi kwamacandelo abahambisi
Okubizwa ngokuba yi-short circuit phakathi kwamacandelo abahambisi kuthetha ukuba kukho uxhulumaniso olufutshane lwesekethe phakathi kwamacandelo amabini asondeleneyo nabahambisi kwi-commutator. Isiphaluka esifutshane phakathi kwamacandelo abahambi. Iintlantsi ezinkulu ziya kubonakala kumphezulu womhambisi; xa isiphaluka esifutshane sinzima, umlilo we-ring uya kwenzeka kumphezulu womqhubi.

Ukulungiswa kwesekethe emfutshane phakathi kwamacandelo abathuthi kungokulandelayo:
① Ukucoca ngeshiti lokucoca i-slot Xa i-armature winding itshiswa ngenxa yesiphambeko se-short-circuit, indawo ephosakeleyo inokufunyanwa ngendlela yokujonga. Ukuze unqume ukuba ngaba i-short-circuit iphoso yenzeke ngaphakathi kwi-winding okanye phakathi kwamacandelo abahambisi, intloko yocingo olujikelezayo oludityaniswe kwicandelo lomhambisi kufuneka luqhawulwe, kwaye emva koko usebenzise ukukhanya kwetshekhi ukujonga ukuba kukho isiphaluka esifutshane phakathi komhambisi. amacandelo, njengakumphezulu wecandelo labahambisi. Ukuba isiphaluka esifutshane sifunyenwe, okanye i-spark itshisa isiva, ngokuqhelekileyo sebenzisa i-slot yokucoca sheet eboniswe kuMfanekiso 227 ukukrazula iitshiphu zetsimbi ezijikelezayo ezimfutshane, umgubo webrashi, izinto ezibolayo, njl. khangela ukuba akukho sikhewu esifutshane. Kwaye sebenzisa i-mica powder kunye ne-shellac okanye i-mica powder, i-epoxy resin kunye ne-polyamide resin (i-650) ukudibanisa kwi-paste, uze ugcwalise i-grooves kwaye uyivumele ibe nzima kwaye yome.
②Clean the V-groove and V-ring of the commutator block If the short circuit between the chips cannot be eliminated after carefully removing the external debris between the chips. At this time, the commutator must be disassembled, and the V-groove and V-ring of the commutator group must be carefully cleaned. Before disassembling the commutator, wrap a layer of elastic paper with a thickness of 0.5 to 1 mm on the outer circumference of the commutator for insulation, and mark the fault location, and then cover the stacking die, and then Take the commutator apart. Further check the faults between the commutator segments, the surface of the V-groove and the V-ring, and deal with them according to different faults.
③ Ukutshintshwa kwamaphepha e-mica phakathi kwamaphepha Ukuba isiphaluka esifutshane phakathi kwamaphepha asikwazi ukupheliswa ngale ndlela ingasentla, kuphela ngamacwecwe e-mica anokutshintshwa. Indlela yokutshintsha i-inter-chip mica flakes yile ilandelayo.
Beka eli candelo lingentla liqhawulwe kwipleyiti ethe tyaba, phawula izahlulo zesihambisi esinempazamo, uze emva koko usiqhoboshele ngeringi yerabha, emva koko susa ihupula yentsimbi okanye ucingo lweglasi olungenaweft, kwaye usebenzise icandelo elibukhali A leblade yesarha ebanzi. ifakwe phakathi kweengcezu eziphosakeleyo, emva kokukhulula, isiqwenga somqhubi esiphosakeleyo sitsalwa ngaphandle, kunye neqhekeza elitsha le-commutator yenkcazo efanayo kunye neqhekeza le-commutator eliphosakeleyo lifakiwe.
Emva kokuba ipleyiti yabahambi itshintshiwe, sebenzisa iihupula zentsimbi (ezinekhadibhodi eshinyeneyo ngaphakathi) ukuqhobosha iqela lepleyiti yabahambisi. Fudumeza ibhloko ye-commutator ukuya kwi-165℃±5℃, qinisa izikhonkwane okokuqala, kwaye usebenzise isibane sokulinganisa ukujonga ukuba isiphaluka esifutshane phakathi kweebhloko sisusiwe emva kokupholisa. Ukuba ayipheliswanga, kufuneka ufumane ngononophelo imbangela yokungaphumeleli okanye ukuphinda umsebenzi ongentla; ukuba isiphaluka esifutshane phakathi kweetshiphusi siphelisiwe, yenza indibano.
