Ukukhutshwa ngokuyinxenye kwiNkqubo yokuJonga kwi-Intanethi yeeJenereyitha
Ngokuqhelekileyo, ukukhutshwa kwenxalenye kwenzeka kwindawo apho iipropati zezinto ze-dielectric azifani.Kwezi ndawo, amandla ombane wendawo aphuculwe, kwaye amandla ombane wendawo akhulu kakhulu, okukhokelela ekuqhekekeni kwendawo.Oku kuqhekeka ngokuyinxenye ayikokuwohloka ngokupheleleyo kwesakhiwo sokugquma.Ukukhutshwa okungaphelelanga ngokuqhelekileyo kufuna umlinganiselo othile wesithuba serhasi ukuze siphuhle, esifana nerhasi engaphakathi kwindawo yokugquma, iiconductors ezikufutshane, okanye ujongano lokhuselo.
Xa amandla entsimi yendawo edlula amandla e-dielectric ezinto zokugquma, ukukhutshwa okuyingxenye kwenzeka, okubangela ukuba iipulse ezininzi zokukhupha zenzeke ngexesha lomjikelo omnye wokusebenzisa i-voltage.
Ubungakanani bokukhutshwa okunikezelweyo buhambelana ngokusondeleyo neempawu ezingaqhelekanga kunye neempawu ezithile ze-dielectric zezinto eziphathekayo.
Ukukhutshwa okubonakalayo okubalulekileyo kwi-motor kudla ngokuba luphawu lwe-insulation defects, njengomgangatho wokuvelisa okanye ukuthotywa kwe-post-run degradation, kodwa oku akusona isizathu esithe ngqo sokungaphumeleli.Nangona kunjalo, ukukhutshwa kwenxalenye kwi-motor nako kunokonakalisa ngokuthe ngqo i-insulation kwaye kuchaphazele inkqubo yokuguga.
Imilinganiselo ethile yokukhupha kunye nokuhlalutya inokusetyenziswa ngokufanelekileyo kulawulo lomgangatho we-windings emitsha kunye namacandelo ajikelezayo kunye nokubonwa kwangaphambili kweziphene zokugquma ezibangelwa yimiba efana ne-thermal, umbane, indalo kunye noxinzelelo lomatshini ekusebenzeni, okunokukhokelela ekungaphumeleli kokugquma.
Ngenxa yobuchwephesha bemveliso ethile, iziphene zokuvelisa, ukuguga okuqhelekileyo okanye ukuguga okungaqhelekanga, ukukhutshwa okungaphelelanga kunokuchaphazela ulwakhiwo lwe-insulation yalo lonke i-stator winding.Uyilo lwemoto, iimpawu zezixhobo zokugquma, iindlela zokuvelisa, kunye neemeko zokusebenza zichaphazela kakhulu inani, indawo, indalo, kunye nentsingiselo yophuhliso lokukhutshwa kwenxalenye.Kwiimeko ezininzi, ngeempawu zokukhutshwa ngokuyinxenye, imithombo eyahlukeneyo yokukhutshwa kwendawo inokuchongwa kwaye yahlulwe.Ngokusebenzisa intsingiselo yophuhliso kunye neeparamitha ezinxulumeneyo, ukugweba imeko yokugquma kwenkqubo, kunye nokubonelela ngesiseko sangaphambili solondolozo.
Ipharamitha yophawu lokukhutshwa kwenxalenye
