I. Chikonzero chekubuda kweropa zvishoma

Mudziyo we transformer, muviri wesimbi nezvimwewo zvinowanzova nekona yakapinza uye burr, saka magetsi anochajwa pasi pesimba remagetsi acharamba ari panzvimbo yakapinza kana burr uye zvichikonzera kuburitswa kwechikamu.

Epoxy resin insulated dry transformer mu vacuum casting, kana kusadzora zvakanaka maitiro kunokonzerawo mabubbles emukati uye zvobva zvaburitsa chikamu chemhepo. Kazhinji pane mipata midiki yemhepo mu epoxy resin insulator, uye kazhinji dielectric coefficient yemabubbles yakaderera zvikuru pane insulator, nekudaro, simba remagetsi rebubble mu insulator rakakwira zvakanyanya kupfuura rezvinhu zvinodzivirira zviri pedyo, saka zviri nyore kusvika padanho rekubudirira uye kuita kuti mabubbles atange abuda emagetsi.

Kana kubatana kwemagetsi pakati pemuchina unofambisa magetsi kusina kunaka, zviri nyore kuburitsa magetsi, ayo ari iwo anonyanya kukonzera simbi kusundidzirwa.

Hunyoro hwemhepo yakawanda, simba rekudzivirira kwechikamu chekuchinja hazvina kukwana, kana kuti kudzivirira kwetransformer kunokuvara panguva yekuisa, nguva yekushanda kwetransformer yakareba zvakanyanya, huwandu hwemvura muzvinhu zvinodzivirira hunopfuura mwero, uye muviri wese wetransformer wakanyorova, izvo zvinokanganisawo kubuda kwechikamu.

Simba rema "layer" kana "turns" rakanyanya kukwira pakugadzira "dry transformer insulation structure", senge "insulation structure design" hazvina musoro, "low quality insulation tool" haina kunaka, "winding", "omesa" uye "durulla" haina kunaka, "assembling" haina kunaka sekugadzirwa kwe "high and low voltage wire lead" ine "burrs" kana kuti "distance" yakati wandei, zvese izvi zvinokanganisa "partial discharge" kuti iwedzere.

II.Njodzi Yekubuda Muropa Zvishoma

Kune mhando dzakasiyana-siyana dzekuburitsa mvura muchikamu. Imwe imhando yekuburitsa mvura muchikamu chinoitika pamusoro pechinhu chinodzivirira kupisa. Kana simba rayo rakakura, chiratidzo chekuburitsa mvura muchikamu chinochengetedza kupisa chichaiswa pamusoro pechinhu chinodzivirira kupisa uye chichakanganisa hupenyu hwe transformer. Kunewo simba guru rekuburitsa mvura muchikamu chinopinza kupisa, chinoitika mu cavitation kana sharp electrode, chakabatanidzwa muchimiro chekuburitsa mvura muchikamu chinoparadza kupisa, chinogona kupinda muzvikamu nekudzika kwebhodhi rinodzivirira kupisa kupisa, uye pakupedzisira chinotungamira mukubuda kwesimba.

Kubuda kwechikamu ndicho chikonzero chikuru chekukwegura kweinsulation uye breakthrough. Nguva pfupi yekubuda kwechikamu haizokonzere kukuvara kwe dielectric yechiteshi chose, uye kushanda kwe electrolytic kwekubuda kwechikamu kunokurumidza oxidation yeinsulation, uye kunoparadza insulation, saka hupenyu hwe transformer hunoderera. Dhigirii rekukuvadzwa rinoenderana nekushanda kwekubuda uye mashandiro ekukuvadzwa kweinsulation iri pasi pekubuda. Kana kubudiswa kwechikamu che transformer yakaoma kwakapfuura zvakanyanya mwero wayo wenguva dzose, hupenyu hwayo hwebasa mumakore 3-5 kukwegura kwemukati kweinsulation uye breakthrough zvichaitika. Saka kubudiswa kwechikamu che transformer yakaoma kunofanirwa kudzorwa zvakanyanya muChina.

III. Kudzora Kubuda Kwemvura Muchinje Chakaoma
Chinhu chikuru chekudzivirira chetransformer yakaoma iepoxy resin, yakachengeteka uye yakavimbika, musimba remagetsi pasi pe35kV zvigadzirwa zvakashandiswa zvakanyanya. Pane zvinhu zvakawanda zvinokanganisa kuburitswa kwechikamu chetransformer yakaoma, pakati pazvo zvinhu zvikuru kusarudzwa kwezvinhu zvakagadziriswa, dhizaini yechimiro chechigadzirwa, maitiro ekukanda mavhiri nezvimwewo. Tichifunga nezvekugadzirisa dhizaini kwenguva refu kwekambani yedu, kuvandudzwa kwemaitiro, kusarudzwa kwezvinhu uye maitiro ekugadzira, tinoisa matanho ekudzora anotevera.

1. Dhizaini yeChimiro Chinomonereka
(1) Kureba kwekudzivirira, mukugadzirwa kwetransformer winding, kunofanirwa kuve nechokwadi chekuti coil yemagetsi yakakwira neyakaderera, pakati pe coil yemagetsi yakakwira, coil yemagetsi yakakwira pasi ine daro rakakwana rekudzivirira, pasi pemamiriro ezvinhu anobvumirwa, kureba kwekudzivirira kwakawanda, kureba kwesimba remunda kudiki. Kudzivirira kwamadziro muHV coil kunogona kuwedzerwa zvakakodzera kuti kuderedzwa simba rekunze remunda zvinobudirira.
(2) Kugadzirwa kwe coil ine voltage yakakwira pakati pezvikamu nezvikamu, izvo zvinodzora simba remunda we coil, uye kana HV winding ikashandiswa copper foil ine subsection, interlayer voltage yakaenzana ne interturn voltage, kazhinji kacho chete ye 10 kusvika 20 v, sectional pakati pezvikamu zvechimiro che electromagnetic wire voltage i400 ~ 800v, ​​section number inofanira kunge yakawanda, senge 35kv dry-type transformer inodiwa section number inopfuura 16~18 pieces, Ehe, zvinounza matambudziko akawanda kune winder process.
(3) kudzora kudzivirira, kushandisa kudzivirira kunoshanda, mipendero yekucheka, maburi uye mhepo inogona kurongedzwa mukati mechidzitiro, izvo zvinogona kubvisa zvinobudirira kuburitswa kwemagetsi kwemuromo wekuputika, uye kuderedza kuburitswa kwechikamu. HV shield neHV wire end, LV uye clamp zvinofanirwa kunge zvakabatana zvakavimbika, kugadziriswa kwekudzivirira kunofanira kuramba kuchichenesa, zvikamu zvechidzitiro zvinofanirwa kunge zvakatsetseka, zvisina kuputsika uye muromo wakapwanyika, nezvimwewo.

2. Kudzora Kudzora Maitiro Ekudzikisa Makoira, Kuumba uye Kudurura Vacuum

Coil yetransformer yakaoma ndiyo inonyanya kukosha, kushandiswa kwetransformer kwakanaka kana kuti kwete kutadza kwecoil. Mhedzisiro yekudira vacuum yakakoshawo pakuburitswa kwenzvimbo, kunyangwe maburi madiki anokanganisa kuburitswa kwetransformer munzvimbo, saka maitiro ekugadzira nekukanda coil anofanira kudzorwa zvakanyanya.

(1) patinenge tichimonera coil, tinofanira kuziva madhirowa uye maitiro acho, uye hatigone kuchinja nhamba yekutenderera pakati pezvikamu nenhamba yemapepa ekudzivirira pakati pezvikamu! Ita shuwa kuti zvinhu zvese zvakachena patinenge tichimonera.

(2) Pakuisa welding yemold lead terminal, nyatsoteerera kukuvara kwakanyanya kwe coil insulation, welded wire inofanira kuporishwa yakapinza corner burr, nezvimwewo. Iva nechokwadi chekuti lead dzese dzakaputirwa kure zvakakwana kuti dzizadzwe ne epoxy resin uye dzicheneswe panguva yese yekuunganidza. Die coil yakaiswa inoomeswa zvakanyatsoenderana nemaitiro ekuomesa.

(3) epoxy resin zvinosanganisirwa uye degassing, maitiro ekubatanidza anofanirwa kutevedzera tekinoroji yekodhi, senge zvinhu, chiyero chekusanganisa, tembiricha nenguva yekubvisa gassing, viscosity yedhigirii inofanira kutevedzera zvakanyatsoenderana, dhigirii re vacuum, tembiricha uye chiitiko chebubble, kusanganisa, tembiricha yekudurura uye dhigirii re vacuum zvinochengetedza coil yekutarisa (mould) mukati mechiyero chekudzora tembiricha mumaitiro akatarwa. Mukuita kwekudurura, kumhanya hakufanirwe kuve kwakanyanya kukurumidza uye kugadzira mabubble. Kana kudurura kwakasimba, kutarisirwa kunofanirwa kupihwa kune nguva mushure mekushandisa zvinosanganisirwa kuti kupedzwa kwekudurura kudzivirire viscosity ye resin yakakura zvakanyanya.

3. Kusarudzwa uye kutonga kwezvinhu zvakagadzirwa

(1) Kusarudzwa kwewaya yemagetsi, kunogona kusarudza waya ye enamel inoputira mhangura yakatsetseka kana dhizaini yewaya yemhangura yakatenderera; vatengesi vewaya yemagetsi vari kugadzirwa, vanofanirwa kunge vaine michina yakakosha yekubvisa maburi nemidziyo yekuona, uye vanoedza kuderedza maburi kusvika padiki.

(2) kusarudzwa kwezvinhu zve epoxy resin, epoxy resin yakasiyana, hunhu hwayo hwakasiyana, kuburitswa kwechigadzirwa munzvimbo yacho, kushanda kwakazara kwemhedzisiro yacho kwakanakawo, unofanirwa kusarudza viscosity diki, kuomarara kwakanaka, simba guru rekuputira resin, modhi yakasiyana ye resin, uye dhipatimendi rehunyanzvi rekugadzira marongero anoenderana.

(3) kudzora zvinhu zvinodzivirira kupisa mu coil, mhando yezvinhu zvinodzivirira kupisa pakati pezvikamu zve transformer yakaoma ine chekuita zvakananga nehukuru hwenzvimbo yacho. Saka, vatengesi venguva refu uye vakagadzikana vanofanira kusarudzwa kuti vape zvinhu zvakagadziriswa, nekuti mushure mekuchinja zvinhu zvitsva, transformer haigone kuwana matambudziko munguva pfupi.
