Oiri yetransformer Mumamiriro emvura, transformer mukufambisa, kuchengetedza, uye kushandiswa inogona kupinzwa nekunze kana okisijeni yemvura pachayo, mvura inogadzirwa ichavepo mune zvinotevera: imwe imvura yakasununguka. Chechipiri ndechekuti zvidimbu zvitete kwazvo zvinonyunguduka mumvura. Molekyuru yefiber inochengetedza iglucose (C6H12O6) molecule. Kana mvura ikapinda mumolekyuru yefiber, inoderedza kukwezva kwayo, inosimudzira hydrolysis yayo kuita zvinhu zvine mamorekuru mashoma, uye inoderedza simba remuchina uye mwero wepolymerization yefiber.

Parizvino, transformer yemagetsir haisi imwe yemidziyo inonyanya kukosha uye inodhura mumagetsi, asiwo imwe yemidziyo inokonzera tsaona dzakawanda mumagetsi. Transformer isati yangoerekana yakundikana, kuora kweinsulation uye kukanganisa kwakavanzika kuchaburitsa mhedzisiro dzakasiyana siyana neruzivo rwakadai sechiedza, magetsi, ruzha, kupisa uye shanduko dzemakemikari pasi pesimba remagetsi anoshanda. Naizvozvo, kwete chete kuchengetedza kudzivirira kwakavakirwa pamiedzo yekudzivirira kunofanirwa kuitwa nguva dzose kumba nekune dzimwe nyika, asiwo nzira dzekufanotaura dzekuchengetedza dzakavakirwa pakutarisa online dziri kudzidzwa kuitira kutarisa nekuongorora zvikanganiso kana zvikanganiso zvinogona kuitika online munguva chaiyo kana nguva dzose. Hunyoro huri mumafuta e transformer insulation zvakare chiyero chekuona hunhu hwe insulation ye transformer. Transformer online intelligent diagnostic michina inogona kuunganidza otomatiki, kuongorora zviri mumvura mumafuta uye kuwana chikonzero chekukundikana, kupa mhinduro, vashandisi kugadzirisa njodzi dzakavanzika dziripo mu transformer nenguva, kudzivirira tsaona.

1. Mamiriro uye kukuvadzwa kwehunyoro mumafuta etransformer

Muchina wekushandura mafuta uri mukufambisa, kuchengetedza uye kushandisa unogona kupindwa nenyika yekunze kana oxidation yemafuta pachayo kuti ugadzire mvura, mvura inogadzirwa ichavepo mune zvinotevera:

Imwe mvura yemahara. Kuti mvura ipinde kunze, senge isiri nyore kuisanganisa nemvura. Hazvikanganisi voltage yekupwanyika kwemafuta, asiwo hazvibvumiri, zvichiratidza kuti panogona kunge paine mvura yakanyungudutswa mumafuta, kurapwa nekukurumidza.

Chechipiri ndechekuti zvidimbu zvitete kwazvo zvinonyungudika mumvura. Kazhinji zvinobva mumhepo zvichienda mumafuta, zvichideredza zvakanyanya kuputsika kwemagetsi emafuta. Kuwedzera kwekurasika kwepakati, mafuta evacuum filter.

Chechitatu, mvura yakasanganiswa. Kuchenesa mafuta hakuna kunaka, kana kushanda kwenguva refu kunokonzera kukwegura kwemafuta, kana mafuta akasvibiswa ne emulsification, kunoderedza kushushikana pakati pemafuta nemvura, zvakaita semafuta nemvura zvakasanganiswa, zvinoumba mamiriro e emulsified. Wedzera demulsifier.

Kukuvara kwayo: imwe ndeyekuderedza voltage yekupwanyika kwezvigadzirwa zvemafuta. 100 ~ 200mg/kg voltage yekupwanyika yakadzikira kusvika pa1.0kV, tsvina yefaibha iri mumafuta inonyudza mvura zviri nyore, pasi pesimba remagetsi, kuumbwa kwe "bhiriji" rinofambisa magetsi pakati pemaerekitirodhi, saka zviri nyore kupwanyika.

Chechipiri ndechekuwedzera kurasikirwa kwechinhu chiri pakati. Mvura inonyungudutswa ine simba guru uye haina kufanana. Molekyuru yefiber inonyungudutsa iglucose (C6H12O6) molecule. Kana mvura ikapinda mufiber molecule, inoderedza kukwezva kwayo, inosimudzira hydrolysis yayo kuita zvinhu zvine mamorekuru mashoma, uye inoderedza simba remuchina uye mwero wepolymerization yefiber. Kuedza kunoratidza kuti 120℃, insulation fiber muhunyoro inowedzera ka1, simba remuchina refiber rinoderera ne1/2, kana tembiricha ikakwira, mvura mumafuta inowedzera, mvura mufiber inoderera, tembiricha inoderera, zvakapesana. Naizvozvo, hunyoro mumafuta hunofanira kutariswa, uye nokudaro kukwegura kwefiber inonyungudutsa kunofanira kutariswa. Chechina ndechekuti mvura inokurudzira kugona kwekuora kweorganic acids uye inokurumidza kuora kwezvikamu zvesimbi. Mukupfupisa, huwandu hwakawanda hwemvura mumafuta, kukwegura kwemafuta pachawo kunokurumidza, kukwegura kwemidziyo inonyungudutsa uye kuora kwezvikamu zvesimbi, saka zvakakosha kutarisa huwandu hwemvura mumafuta, kunyanya huwandu hwemvura yakanyungudutswa.

2. Nzira yekuyedza hunyoro mumafuta e transformer insulation

Kuongororwa kwehunyoro mu zvinhu zvekuputira chinhu chakakosha kuti transformer igare yakavimbika uye inoshanda kwenguva refu. Hunyoro mumafuta ekudzivirira hunogara huchichinja, izvo zvinogona kukanganisa kunaka. Pamusoro pezvo, hunyoro hwakawanda hunoparadzirwa mupepa rekudzivirira hunyoro. Hunyoro hunokanganisa simba rekuputsika kwe dielectric kwezvinhu zvinodzivirira hunyoro uye mvura, uye hunokanganisa mwero wekukwegura kwezvinhu zvinodzivirira hunyoro uye maitiro ekuumbwa kwemabubble panguva yekuwedzerwa kwemafuta.

Kupisa kwenzvimbo, mutoro, kukwegura, kubuda kwemvura, nezvimwe zvinhu zvinogona kukonzera kuchinja kwehunyoro nguva dzose. Nokudaro, kutarisisa nguva dzose uye kuongororwa kunodiwa nekuchinja kwetembiricha yetransformer. Izvi zvinonyanya kukosha kune matransformer ane mutoro wakawandisa kana kuti uri pamusoro. Hunyoro hwese mutransformer insulation system hunotsanangurwa nehuwandu hwehunyoro hwe cellulose nemvura. Hukama hwehunyoro pakati pepepa re insulation nemafuta e insulation hunoenderana chete netembiricha. Sezvo tembiricha ichiwedzera, kunyunguduka kwemvura mumafuta e insulation (simba rekubata mvura remushonga) kunowedzera, uye mvura ichatamiswa kubva papepa re insulation kuenda kumafuta e insulation.

Kana tembiricha yadzikira, maitiro acho anodzokera shure, asi kuyerera kwemvura kubva muchinhu chinonyungudutsa mvura kuenda kuchinhu chinonyungudutsa mvura chakasimba kunononoka. Nokudaro, huwandu hwemvura mumafuta anonyungudutsa panguva yekutonhora hwakakwira kupfuura huri panguva yekupisa. Saka, kuti unzwisise zvakanaka kugoverwa kwehunyoro mutransformer, zvakakosha kuziva nzvimbo yemuchina mukupisa kwayo. Kuti unzwisise hunyoro hwechokwadi hwepepa rinonyungudutsa mvura nekutarisa hunyoro muchinhu chinonyungudutsa mvura, transformer inofanira kunge iri mumamiriro ekupisa akagadzikana.

Kuwanda kwemvura mumafuta ekudzivirira kunofanirwa kuenzaniswa nekuti hunyoro mumafuta ekudzivirira kunoenderana nekuchinja kwetembiricha uye pane mwero wekupisa mubhokisi guru retransformer (kazhinji pamusoro pebhokisi panodziya kupfuura pasi). Kuti upedze kuyera, ongororo yehunyanzvi hwesystem inowana huwandu hwehuwandu hwemvura pasi. Izvi zvinogona kuwanikwa nekushandisa tembiricha yakataurwa nesensor nenzvimbo yayo yesampuro.

Ongororo iyi inofunga kuti tembiricha yepamusoro yetransformer yakakwira ne10℃ kupfuura tembiricha yepasi. Kana nzvimbo isiri yepamusoro kana pasi ikashandiswa senzvimbo yekutora sampuli, kutsauka kwetembiricha kunofanirwa kutsanangurwa. Kuburikidza nekuzara kwehunyoro uye tembiricha yakayerwa, sisitimu yenyanzvi ichave nehuwandu hwakati wandei hwehuwandu hwehuwandu hwemhedzisiro yekuverenga hunyoro hwepepa rekudzivirira. Zvakakosha kuziva kuti kuverenga uku kwakavakirwa paruzivo kubva pakuyera kumwe chete uye kungasaratidze huwandu hwehunyoro hwepepa rekudzivirira, kunyanya mushure mekunge transformer yachinja zvakanyanya tembiricha.

Kana sisitimu yenyanzvi ikaona kuti transformer iri mu equilibrium (pepa rekudzivirira hariburitse kana kunyudza hunyoro), chikamu chechipiri che relative saturation chinoverengerwa, inova avhareji yezviyero makumi matatu zvekupedzisira zve relative saturation percentage kana transformer iri mu equilibrium. Tembiricha uye musiyano zvakanyorwa pamusoro apa zvinosarudza nzira dzekuziva kuvapo kana kusavapo kwe equilibrium.

Tine mhando dzemidziyo yekuyedza yeTransformer oil test, yakaita se: Interfacial Tension Tester, Oil Particle Counter tester, Pour point test nezvimwewo. Kana muine mubvunzo, ndapota taurai nesu makasununguka.
