1.Lub luag hauj lwm ntawm dipping xim

1. Txhim kho cov dej noo-pov thawj muaj nuj nqi ntawm lub cev muaj zog windings.

Nyob rau hauv lub winding, muaj ntau qhov pores nyob rau hauv lub qhov rwb thaiv tsev, interlayer rwb thaiv tsev, theem rwb thaiv tsev, khi xov hlau, thiab lwm yam.Nws yog ib qho yooj yim mus nqus noo noo nyob rau hauv cov huab cua thiab txo nws tus kheej rwb thaiv tsev kev ua tau zoo. Tom qab dipping thiab ziab, lub cev muaj zog muaj cov xim insulating thiab tsim cov xim pleev xim zoo nkauj, uas ua rau nws nyuaj rau ya raws thiab corrosive gases rau invade, yog li txhim kho cov dej-pov thawj thiab corrosion-resistant zog ntawm winding.

2.Txhim kho qhov hluav taws xob rwb thaiv tsev lub zog ntawm winding.

Tom qab cov windings tau dipped nyob rau hauv cov xim thiab qhuav, lawv lem, coils, theem thiab ntau yam ntaub ntawv insulating yog sau nrog insulating xim nrog zoo dielectric zog, ua rau lub rwb thaiv tsev lub zog ntawm windings ntau dua ua ntej dipping nyob rau hauv cov xim.

3.Txhim kho cua sov dissipation tej yam kev mob thiab enhanced thermal conductivity.

Qhov kub nce ntawm lub cev muaj zog thaum lub sijhawm ua haujlwm ntev ncaj qha cuam tshuam rau nws lub neej kev pabcuam. Lub cua sov ntawm winding yog pauv mus rau lub dab dej kub los ntawm lub qhov hluav taws xob rwb thaiv tsev. Qhov loj qhov sib txawv ntawm cov ntaub ntawv rwb thaiv tsev hlau ua ntej varnishing tsis yog qhov zoo rau kev ua kom sov hauv qhov winding. Tom qab varnishing thiab ziab, cov khoob no tau ntim nrog cov kua roj vanish. Lub thermal conductivity ntawm insulating cov kua roj vanish yog zoo dua li ntawm cov huab cua, yog li zoo heev txhim kho cov cua kub dissipation tej yam kev mob ntawm winding.

2. Hom insulating kua roj vanish

Muaj ntau hom xim insulating, xws li epoxy polyester, polyurethane, thiab polyimide. Feem ntau, cov xim insulating sib raug tau raug xaiv raws li qib kub, xws li 162 epoxy ester liab enamel qib B (130 degrees), 9129 epoxy hnyav-dawb topcoat F (155 degrees purified), 1. degrees), Nyob rau hauv cov xwm txheej uas cov xim insulating ua tau raws li qhov yuav tsum tau ua kom sov, nws yuav tsum raug xaiv raws li ib puag ncig ntawm lub cev muaj zog, xws li thermal conductivity, noo noo tsis kam, thiab lwm yam.

3.Tsib hom txheej txheem varnishing

1. Npog

Thaum kho ib lub cev muaj zog, lub winding varnishing tuaj yeem nqa tau los ntawm cov txheej txheem pouring.Thaum lub ncuav, tso lub stator vertically ntawm cov xim tha xim nrog ib kawg ntawm winding tig upward, thiab siv lub lauj kaub xim los yog xim txhuam los pleev xim rau ntawm qhov kawg ntawm lub winding.Thaum qhov sib txawv winding yog sau nrog cov xim thiab pib nkag mus rau lwm qhov kawg ntawm cov cua ntsawj ntshab ntawm qhov sib txawv. kawg kom txog thaum nws puv puv.

2.Drip leaching

Txoj kev no yog tsim rau varnishing ntawm me me thiab nruab nrab-qhov loj qhov hluav taws xob motors.

①Formula. 6101 epoxy resin (mass ratio), 50% tung oil maleic anhydride, npaj siv.

②Preheating: Ua kom sov lub cua sov li 4 feeb, thiab tswj qhov kub ntawm 100 thiab 115 ° C ( ntsuas nrog lub ntsuas kub ntawm qhov chaw), los yog muab cov cua sov tso rau hauv qhov cub kom qhuav thiab ua kom sov li 0.5 teev.

③Drip. Muab lub cev muaj zog stator vertically rau ntawm lub tais xim, thiab pib cov xim pleev xim manually thaum lub cev muaj zog kub poob rau 60-70 ℃. Tom qab 10 feeb, tig lub stator tshaj thiab drip xim rau lwm qhov kawg ntawm winding kom txog thaum nws tau ntub dej kom huv.

④ Kev kho mob. Tom qab dripping, lub winding yog energized rau kho, thiab winding kub yog tswj ntawm 100-150 ° C; Cov nqi hluav taws xob tiv thaiv raug ntsuas kom txog thaum nws tsim nyog (20MΩ), lossis cov cua nkag tau muab tso rau hauv lub qhov cub kom qhuav kom sov ntawm tib qhov kub li 2 teev (nyob ntawm qhov loj ntawm lub cev muaj zog), thiab nws raug tshem tawm ntawm qhov cub thaum lub rwb thaiv tsev tiv thaiv siab tshaj 1.5MΩ.

3. Roller xim

Txoj kev no yog tsim rau varnishing ntawm nruab nrab motors. Thaum dov cov xim, ncuav cov xim pleev xim rau hauv lub tank xim, tso lub rotor rau hauv lub tank xim, thiab cov xim pleev xim yuav tsum raus lub rotor winding rau ntau tshaj 200 hli. Yog hais tias lub tank xim yog ntiav heev thiab qhov chaw ntawm lub rotor winding rau hauv cov xim yog me me, lub rotor yuav tsum tau dov ob peb zaug, los yog cov xim yuav tsum tau siv nrog ib tug txhuam hniav thaum lub rotor dov. Feem ntau dov 3 mus rau 5 zaug tuaj yeem ua rau cov xim insulating nkag mus rau lub rwb thaiv tsev.

4. Kev tso dej tawm

Thaum kho cov motors me me thiab nruab nrab hauv cov khoom siv, cov windings tuaj yeem muab tso rau hauv cov xim. Thaum immersing, thawj zaug muab ib tug zoo npaum li cas ntawm insulating xim rau hauv cov xim muaj peev xwm, ces dai lub cev muaj zog stator nyob rau hauv, kom cov xim kua submerges lub stator los ntawm ntau tshaj 200 hli. Thaum cov kua pleev xim nkag mus rau txhua qhov sib txawv ntawm cov windings thiab cov ntawv insulating, lub stator yog lifted thiab cov xim yog dripped. Yog tias 0.3 ~ 0.5MPa siab ntxiv thaum lub sij hawm immersion, cov nyhuv yuav zoo dua.

5.Nqus siab immersion

Lub windings ntawm high-voltage motors thiab me me thiab nruab nrab motors nrog siab rwb thaiv tsev zoo yuav tsum raug rau lub tshuab nqus tsev siab dipping. Thaum lub sij hawm dipping, lub stator ntawm lub cev muaj zog yog muab tso rau hauv ib lub thawv xim kaw thiab noo noo raug tshem tawm siv tshuab nqus tsev. Tom qab cov windings yog dipped nyob rau hauv cov xim, ib tug siab ntawm 200 mus rau 700 kPa yog siv rau cov xim nto kom tso cai rau cov xim cov kua nkag mus rau hauv tag nrho cov seem ntawm cov windings thiab sib sib zog nqus mus rau hauv lub qhov hws ntawm cov ntaub ntawv insulating kom zoo dipping.
