Ho na le mefuta e mengata ea mechine ea motlakase e potolohang.Ho ea ka mesebetsi ea bona, li arotsoe ka lijenereithara le li-motors.Ho ea ka mofuta oa motlakase, li arotsoe ka li-motor tsa DC le li-motors tsa AC.Ho ea ka libopeho tsa bona, li arotsoe ka li-motor synchronous le motors asynchronous.Ho ea ka palo ea mekhahlelo, li-motors tsa asynchronous li ka aroloa ka li-motor tse tharo tsa asynchronous motors le li-motor tsa asynchronous tse le 'ngoe;ho ea ka mekhoa ea bona e fapaneng ea rotor, li arotsoe ka mefuta ea cage le maqeba a rotor.Har'a tsona, li-motors tsa cage tse tharo tsa asynchronous li bonolo ka sebopeho le ho etsoa.Bonolo, theko e tlase, ts'ebetso e tšepahalang, e sebelisoang haholo ho li-motors tse fapaneng, tlhokahalo e kholo ka ho fetisisa.Tšireletso ea lehalima ea mechine ea motlakase e potolohang (lijenereithara, lik'hamera tse lokisang, li-motor tse kholo, joalo-joalo) li thata haholo ho feta tsa li-transformer, 'me lebelo la kotsi ea lehalima le atisa ho feta la li-transformer.Lebaka ke hore mochine oa motlakase o potolohang o na le litšobotsi tse ling tse fapaneng le transformer mabapi le sebopeho sa ho kenya letsoho, ts'ebetso le ts'ebetso ea ho kopanya.
(1) Har'a lisebelisoa tsa motlakase tsa boemo bo tšoanang ba motlakase, sekhahla sa ho mamella voltage ea mochini oa motlakase o potolohang ke se tlase haholo.
Lebaka ke: ① Enjene e na le rotor e potolohang ka lebelo le holimo, ka hona e ka sebelisa sehare se tiileng feela, 'me e ke ke ea sebelisa mokelikeli o tiileng (oli ea transfoma) e kopanyang motsoako o mahareng joalo ka transformer: nakong ea ts'ebetso ea tlhahiso, sehare se tiileng se senyeha habonolo. , 'me ho koala ke Li-voids kapa likheo li atisa ho etsahala, kahoo ho tsoa ka mokhoa o sa fellang ho tloaelehile ho etsahala nakong ea ts'ebetso, e leng se lebisang ho senyeha ha mocheso;②Maemo a ts'ebetso ea motlakase oa motlakase ke a matla ka ho fetisisa, a itšetlehile ka liphello tse kopantsoeng tsa mocheso, ho sisinyeha ha mechine, mongobo moeeng, tšilafalo, khatello ea motlakase, joalo-joalo, lebelo la ho tsofala le potlakile;③ Sebaka sa motlakase sa mohaho oa motlakase oa motlakase se batla se tšoana, 'me coefficient ea eona ea tšusumetso e haufi le 1. Matla a motlakase tlas'a overvoltage ke khokahanyo e fokolang ka ho fetisisa.Ka hona, matla a lekantsoeng le boemo ba ho kenella ka motlakase ha bo khone ho ba holimo haholo.
(2) Matla a setseng a sets'oants'o sa lehalima se sebelisetsoang ho sireletsa koloi e potolohang a haufi haholo le motlakase oa motlakase oa motlakase oa motlakase, 'me moeli oa ho kenya letsoho o monyenyane.
Mohlala, tlhahiso ea feme e mamellang boleng ba tlhahlobo ea motlakase ea jenereithara e phahame ka 25% ho isa ho 30% feela ho feta boleng ba 3kA bo setseng ba motlakase oa zinc oxide arrester, 'me moeli oa sets'oants'o sa matla a khoheli o nyane, mme moeli oa ho kenella o tla ba teng. tlase ha jenereithara e sebetsa.Ka hona, ha hoa lekana hore enjene e sireletsoe ke sets'oants'o sa lehalima.E tlameha ho sireletsoa ke motsoako oa li-capacitor, li-reactors le likarolo tsa cable.
(3) The inter-turn insulation e hloka hore moepa oa leqhubu le kenang o fokotsehe ka thata.
Hobane matla a inter-turn a motor matsoelintsoeke e nyenyane le discontinuous, overvoltage leqhubu le ka feela propagate hammoho le matsoelintsoeke conductor ka mor'a hore e kene ka enjene matsoelintsoeke, 'me bolelele ba mong le e mong thinya ea matsoelintsoeke ke e kholoanyane ho feta ea transformer matsoelintsoeke. , e sebetsang ka thinya e 'meli e bapileng.E le ho sireletsa "inter-turn insulation" ea enjene, ho teba ha leqhubu le kenang ho tlameha ho fokotsoa ka thata.
Ka bokhutšoanyane, litlhoko tsa tšireletso ea lehalima tsa mechine ea motlakase e potolohang li phahame ebile li thata.Hoa hlokahala ho ela hloko ka botlalo litlhoko tsa ts'ireletso ea "insulation" e kholo, "inter-turn insulation" le "insulation point" e sa nke lehlakore.
