Ngaba i-insulation material ye-motor inqunywe ngubukhulu bangoku okanye i-voltage?

Ngaba i-insulationimpahlayemoto egqitywe bubungakanani bangoku okanye amandla ombane?

Izinto zokugqumasisixhobo esibalulekileyo kwiimveliso zeemoto. Iimotor ezinamaqondo ombane ahlukeneyo anomahluko omkhulu kulwakhiwo lokugquma kwee-windings zazo kunye nezinto zazo eziphambili. Ngokomzekelo, i-insulation structure ye-high-voltage motor kunye ne-low-voltage motor windings yahluke kakhulu. .

Izinto zokugquma, ekwaziwa ngokuba yi-dielectrics, zizinto ezinokumelana okuphezulu kakhulu kunye nokuqhuba kakubi kakhulu. Zikwasetyenziswa kwiimveliso zeemoto ngenxa yokungaqhubi kakuhle kwazo. Kwiimveliso zeemoto, ngokusebenzisa izinto zokugquma, kwelinye icala, iingcingo zokuqhuba zixhunyiwe kunye namanye amacandelo. Ukwahlula, ngakolunye uhlangothi, kukwahlula amanqaku ahlukeneyo omgca wokuqhuba, njenge-inter-turn insulation kunye ne-inter-phase insulation. Izixhobo ezahlukeneyo zokugquma zinokuba neepropathi ezahlukahlukeneyo ezifana nenkxaso, ukulungiswa, ukucima i-arc, ukuxhathisa ukubola, ukukhuselwa kwemitha kunye nokuxhathisa ukubola.

Ukutshisa i-motor windings yimbonakaliso yekhonkrithi yokuwohloka okanye ukunyamalala kokusebenza kwe-insulation. Ke, ngaba ukusebenza kwe-insulation yemoto kuthotywa ngenxa yomoya omkhulu ojikajikayo okanye amandla ombane aphezulu?

Xa i-motor winding yangoku inkulu kakhulu, ukuxinana okuphezulu kwangoku kuya kubangela ukuxhathisa kwamajiko-jiko kunyuke kwaye kubangele ubushushu obukhulu. Ubushushu obuveliswa yi-motor buya kuchithwa nge-insulation. Xa ubushushu bufikelela kwinqanaba elithile, ulwakhiwo lwezixhobo zokugquma ziya kutshintsha umgangatho, njengemoto.izinto zokugqumainokumelana.

Kwi-motor winding, iimfuno ze-insulation phakathi kokujika kunye nokujika, phakathi kwezigaba ezahlukeneyo ze-motor multi-phase, kunye naphakathi komqhubi kunye nomhlaba zibandakanyeka. Xa i-voltage elinganisiweyo ye-motor iphezulu, i-voltage ye-insulation ejikelezayo iphezulu, enokuthi ibe lula Cinga oku njenge-capacitors ezahlukeneyo. Ukuba i-voltage phakathi kwe-capacitors iphezulu kakhulu, iya kukhokelela kwingxaki yokuchithwa kwe-capacitor, oko kukuthi, ukungaphumeleli kwe-insulation ye-motor winding emhlabeni, phakathi kokujika kunye naphakathi kwezigaba.

Ukusuka kulo mxholo ungasentla, sinokuqonda ukuba nangona i-motor ye-high-voltage encinci incinci, i-voltage ye-insulation ye-windings iphezulu, ngoko ke kufuneka kusetyenziswe isakhiwo esikhethekileyo sokufakelwa kombane ukuqinisekisa ukuba ukusebenza kombane we-motor kuyahlangabezana neemfuno. ; ngelixa i-motor low-voltage, ngenxa yokuba i-voltage ye-insulation iphezulu ngoko ke, ukukhethwa kwezinto zokukhusela kulula, kodwa ukuxinana kwangoku, ukungena komoya kunye nokutshatyalaliswa kobushushu zizinto eziphambili zokuqinisekisa ukusebenza kombane wemoto. Yangoku kunye nombane wemoto zineempembelelo ezahlukeneyo kwiizinto zokugqumakwaye kufuneka ithathelwe ingqalelo ngaxeshanye.
