Kutenderedza Transformer Inonyudzwa Mumafuta: Ruzivo Rwehunyanzvi uye Magadzirirwo Azvo

Transformer Inonyudzwa muOiri Mawindings zvinhu zvakakosha mumasisitimu ekugovera magetsi, akagadzirirwa kutamisa simba remagetsi zvinobudirira uku achiva nechokwadi chekuti rakavimbika uye rinogara kwenguva refu. Pazasi pane ongororo yakadzama yemaumbirwo aro, zvinhu, uye misimboti yekushanda, yakagadzirwa kubva pamitemo yeindasitiri uye hunyanzvi.

Tembiricha yepamusoro yetransformer inonyudzwa mumafuta haibvumidzwe kudarika 95 ° C, kazhinji haibvumidzwe kudarika 85 ° C, sarudzo yakajairika yetransformer winding yezvinhu zve class A insulation layer, tembiricha yepamusoro inobvumidzwa yezvinhu zve insulation i95 ~ 105 ° C, muChina, zvirevo zve transformer heating zvinoenderana netembiricha yekushanda ye40 ° C seyakajairwa, winding yeavhareji yetembiricha yegesi inosanganisirwa mu65 ° C. Kukwira kwetembiricha yemafuta epamusoro kuenda kugasi kwakaiswa nemazvo pa55 ° C, saka winding ine core yetransformer inosanganisirwa mukukwira kwetembiricha yemafuta pa10 ° C.

Kana tembiricha yepamusoro yetransformer iri 85 ° C, tembiricha yekumonera iri 95 ° C; Kana tembiricha yepamusoro iri 95 ° C, tembiricha yekumonera yasvika 105 ° C, iyo yasvika tembiricha yepamusoro inobvumirwa yezvinhu zvekumonera zvekumonera. Tembiricha yakanyanya kukwidza ichakurumidzisa kukwegura kwezvinhu zvekumonera zvekumonera, ichakurumidzisa kuora kwemafuta etransformer, uye ichakanganisa hupenyu hwebasa retransformer. Transformer yekugoveras, uye zvinotokonzera tsaona dzekuchengetedza.

Sisitimu yakasimba yekutenderera kwemafuta inotonhorera nemhepo, tembiricha yepamusoro 75℃ ichidziya 35℃; Sisitimu yekutenderera kwemafuta yechisikigo, dziviriro yekupisa kwakanyanya, transformer inotonhorera nemhepo, tembiricha yepamusoro kazhinji haikodzeri kazhinji inopfuura 85 ° C, kupisa kwepamusoro hakugone kudarika 95 ° C hakugone kudarika 55 ° C, kana muganho ukawanikwa mukushanda kwemutengo unodarika zvinodiwa, unofanirwa kuzivisa nguva yekugadzira, kushandiswa kwemuganho wemutoro kunodzivisa.

1. Tsanangudzo uye Basa Guru

Mawinding etransformer anonyudzwa mumafuta anosanganisira coils dzemhangura kana dzearuminiyamu dzakatenderedzwa nesimbi yesilicon ine laminated. Mawinding aya akazara mumafuta anodziisa, ayo anoshanda mabasa maviri: ​electrical insulation​ uye ​thermal management. Mawinding aya anoshandura high-voltage input kuita lower-voltage output (kana kuti zvinopesana) kuburikidza ne electromagnetic induction, zvichiita kuti simba rifambiswe zvakanaka pamagrid.

2. Kuumbwa kwezvinhu

Zvinhu Zvinotungamirira:

Mhangura: Inonyanya kushandiswa pakufambisa mavhiri ane simba guru nekuda kwekufambisa kwayo simba uye simba remakanika. Mavhiri ane simba shoma (≤500 kVA) anowanzo gadzira chimiro che cylindrical chine mativi maviri, nepo simba guru (≥630 kVA) richishandisa magadzirirwo e double-helix kana quadruple-helix kuti riwedzere kugoverwa kwemagetsi.

Aluminum: Dzimwe nguva inoshandiswa pakushandisa zvinhu zvinodhura zvishoma, kunyange zvazvo isingashande zvakanaka semhangura.
Kudzivirira:

Zvinhu zvinodzivirira kupisa (semuenzaniso, epoxy resins, bepa rakagadzirwa ne cellulose) zvinoparadzanisa mawindings kubva pakati uye mumwe nemumwe.

Kudzivirira kwakawanda kunodzivirira ma "short circuits" kana paine thermal stress kana mechanical deformation.

3. ​Kugadzira Zvivako​

Kurongeka kweKutenderera:

Kutenderedza kweConcentric (Cylindrical): Kunowanikwa mumatransformer ane zvikamu zvitatu, uko mawindings ane voltage shoma anoiswa mukati memawindings ane voltage yakawanda kuderedza kubuda kwemvura.

Kutenderedza Maronda Akakombama: Kunoshandiswa pakushandisa magetsi ane simba guru, nematanho akapatsanurwa kuderedza kurasikirwa kwemagetsi emvura.

Kubatanidzwa kweKutonhodza:

Mawindings anosanganisira maducts emafuta kuti aendese kupisa kuburikidza ne convection yechisikigo kana kuti yakamanikidzwa.

Matangi emafuta ane kongiri anotsiva ma conservators echinyakare, zvichiita kuti mafuta awedzere kupisa ukuwo achichengetedza nzvimbo yakavharwa.

4. Kugadzirisa Mashandiro​

Dhizaini Yekurasikirwa Kwakaderera:

​Amorphous Alloy Cores: Inoderedza hysteresis uye kurasikirwa kwemagetsi e-eddy (semuenzaniso, maS11-M series transformers anowana kurasikirwa kwakaderera ne30% pane mamodheru ekare)

Dyn11 Connection Group: Inoderedza kukanganiswa kweharmonic uye inovandudza kunaka kwesimba nekubvisa third-harmonic currents

Kuramba Kwenguva Pfupi:

Makomputa ekumonera akasimbiswa uye matekiniki ekumonera anotenderera anovandudza kugadzikana kwemuchina panguva yekukanganisa.

Zvifefe zveSilica gel uye Buchholz relay zvinotarisa kusarongeka kwehunyoro uye kuyerera kwemafuta

5. ​Kushandisa uye Kugadzirisa​

Mamiriro Ekutumira:

Zviteshi zvemaindasitiri, magrid emagetsi emumaguta, uye masisitimu esimba rinodzokororwa (semuenzaniso, mapurazi emhepo).

Kukwanisa kwemagetsi kunobva pa50 kVA kusvika 25,000 kVA, uye magetsi anosvika 35 kV

Maitiro Ekugadzirisa:

Kuongororwa kwemafuta nguva dzose uye kuongororwa kwegasi rakanyungudutswa (DGA) kuti zvionekwe kuti insulation yadzikira.

Kufungidzira kwekupisa kuti uone nzvimbo dzinopisa dziri munzvimbo dzakasiyana-siyana.

6. ​Zvitsva muWinding Technology​

Kuisa muchina wevacuum: Kunobvisa mapombi emhepo panguva yekugadzira, zvichivandudza kusimba kwekudzivirira kupisa

Kutarisa Kwakangwara: Masensa anobatidzwa neIoT anoteedzera tembiricha inotenderera uye mafambiro emutoro munguva chaiyo.
