Kuiswa uye kutumirwa kweakaoma-mhando transformers, inotungamirirwa nefekitari yekushandura muChina, yepamusoro-soro, nyanzvi
1. Vhura bhokisi kuti riongororwe usati waiswa
Tarisa uone kana kurongedza kuri muchimiro chakanaka. Mushure mokunge transformer yasunungurwa, tarisa kana data iri pazita rezita rekushandura rinosangana nezvinodiwa zvekugadzira, kana zvinyorwa zvefekitari zvakakwana, kana transformer iri mumamiriro ezvinhu akanaka, kana pane chiratidzo chekuparara kwekunze, kana zvikamu zvakadzingwa. uye yakakuvadzwa, ingave zvikamu zvekutsigira magetsi kana tambo dzekubatanidza kana pane kukuvara, pakupedzisira tarisa kana pane kukuvadzwa uye kushomeka kwezvimedu.
2. Transformer kuiswa
Kutanga tarisa hwaro hwe transformer kuti uone kana pre-yakamisikidzwa simbi ndiro iri nhanho. Panofanira kunge pasina cavitation phenomenon pasi peplate yesimbi kuti ive nechokwadi chekuti hwaro hweshanduko hune kunaka kwekuvhunduka uye kuita kwekunzwa kwekurira, kana zvisina kudaro ruzha rwetransformer mushure mekuiswa ruchawedzera. Zvadaro, shandisa roller kuti uendese transformer kunzvimbo yekuisa, bvisa roller, uye kunyatsogadzirisa transformer panzvimbo yekugadzira, uye kukanganisa kwemazinga ekugadzirisa kunosangana nezvinodiwa zvekugadzira. Pakupedzisira, simbi ina mapfupi emugero anosungirirwa pamakona mana ari pedyo negadziko reshanduko, ndiko kuti, pane pre-embedded simbi ndiro, kuitira kuti nzvimbo ye transformer irege kufamba panguva yekushandiswa.
3. Transformer wiring
Kana wiring, iyo diki chinhambwe pakati pemuviri wakaiswa magetsi uye muviri wakaiswa magetsi kusvika pasi unofanirwa kuve nechokwadi, kunyanya chinhambwe kubva patambo kusvika kune yakakwira-voltage coil. Iyo yakakwirira-ikozvino yakaderera-voltage busbar inofanirwa kutsigirwa yakaparadzana, uye haifanirwe kuve yakanangana neiyo transformer terminal kukonzeresa yakawandisa mechanical tension uye torque. Kana ikozvino yakakura kudarika 1000A (yakadai se2000A low-voltage busbar inoshandiswa muprojekti iyi), bhasibha uye transformer Panofanira kuva nekubatana kwakapfava pakati pematerminal kubhadhara kuwedzera kwekupisa uye kuderera kwe conductor uye kuparadzanisa vibration yebhasibar uye transformer. Kubatana kwemagetsi pane imwe neimwe wiring kunofanirwa kuchengetedza inodiwa yekubata kumanikidza. Elastic elements (senge disc-shaped plastic rings kana spring washers) inofanira kushandiswa. Paunenge uchisimbisa mabhoti ekubatanidza, wrench ye torque inofanira kushandiswa. Iyo torque referensi kukosha yakapihwa nemugadziri inoratidzwa muTafura 1 inoratidzwa
4. Transformer grounding
Nzvimbo yepasi ye transformer iri panheyo ye-low-voltage side, uye inotungamirira kunze kune yakakosha bhoti yepasi, iyo yakanyorwa nechiratidzo chepasi. Iyo yekugadzika kweiyo transformer inofanirwa kuve yakavimbika yakabatana kune inodzivirira yepasi system kuburikidza neiyi nhanho. Kana iyo transformer iine casing, iyo casing inofanira kuvimbika yakabatana neiyo grounding system. Kana iyo yakaderera-voltage divi inotora matatu-phase mana-waya system, iyo isina kwayakarerekera waya inofanira kuvimbika yakabatana kune grounding system.
5. Kuongorora pamberi pekushanda kwetransformer
Tarisa kana zvese zvinosungirirwa zvakasununguka, kana kubatana kwemagetsi kwakaringana uye kwakavimbika, ingave nhambwe yekudzivirira pakati pemuviri wakachajwa nemuviri wakachajwa kusvika pasi inosangana nemirairo, hapafanirwe kunge paine nyaya yekune dzimwe nyika padhuze neshanduko, uye iyo coil inofanirwa. kucheneswa.
6. Debugging before transformer operation
(1) Tarisa chiyero cheshanduko uye boka rekubatanidza re transformer, kuyera kupikisa kweDC kweyakakwira uye yakaderera voltage windings, uye enzanisa mhedzisiro nefekitori yekuyedza data yakapihwa nemugadziri.
(2) Tarisa kudzivirira kwekudzivirira pakati pemakoiri uye coil kusvika pasi. Kana iyo insulation resistance yakadzikira zvakanyanya pane dhizaini yekuyera data, inoratidza kuti transformer inonyorova. Kana kudzivirira kwekudzivirira kwakaderera kupfuura 1000Ω/V (kushanda kwemagetsi), transformer inofanira kuomeswa.
(3) Iyo yekuyedza voltage yestanding voltage test inofanirwa kuenderana nemirairo. Paunenge uchiita yakaderera voltage inomira voltage bvunzo, tembiricha sensor TP100 inofanirwa kuburitswa kunze, uye sensor inofanirwa kudzoserwa kunzvimbo yayo nenguva mushure mekunge bvunzo yapera.
(4) Kana transformer yakashongedzerwa feni, fan inofanirwa kupihwa simba uye kushandwa kuti ive nechokwadi chekushanda kwayo.
7. Muedzo kumhanya
Mushure mekunge transformer yanyatsoongororwa isati yaiswa mukushanda, inogona kupihwa simba rekushanda kwekuyedza. Munguva yekuedzwa kwekuedza, kutarisisa kwakanyanya kunofanirwa kubhadharwa kuti utarise pfungwa dzinotevera. Tarisa uone ruzha rusina kujairika, ruzha uye kudedera. Pane here kunhuhwirira kusina kujairika kwakadai sekunhuwa kwekutsva? Kana paine discoloration inokonzerwa nekupisa kwenzvimbo. Kana kufefetera kwakanaka here. Mukuwedzera, pfungwa dzinotevera dzinofanira kucherechedzwa.
Chekutanga, kunyangwe iyo yakaoma-mhando transformer ine yakasimba hunyoro inopikisa, ichiri kujaira kunyorova nekuti kazhinji yakavhurika chimiro, kunyanya yakaoma-mhando transformer inogadzirwa munyika yangu ine yakaderera insulation level (yakaderera insulation level). Naizvozvo, yakaoma-mhando transformers inogona chete kuwana yakakwirira kuvimbika kana hunyoro hwehukama huri pasi pe70%. Dry-type transformers inofanirwawo kudzivirira kubuda kwenguva refu kudzivirira kunyorova kwakanyanya. Kana iyo insulation yekudzivirira kukosha yakaderera pane 1000/V (inoshanda voltage), zvinoreva kuti transformer yakanyorova zvakanyanya, uye bvunzo kumhanya kunofanirwa kumiswa.
Chechipiri, iyo yakaoma-mhando transformer inoshandiswa nhanho-kumusoro muchiteshi chemagetsi yakasiyana nemafuta-akanyudzwa transformer. Kuvhura-circuit kuvhiyiwa kune yakaderera-voltage kudivi kunorambidzwa, kuitira kuti udzivise kuputira kuparara kweiyo yakaoma-mhando transformer nekuda kwekuwedzeredza padivi regidhi kana kurova kwemheni pamutsetse, zvichikonzera kutapurirana kweovervoltage. Kuti udzivise njodzi yekufambiswa kwe overvoltage, seti ye overvoltage yekudzivirira surge arresters (yakadai seY5CS zinc oxide arresters) inofanira kuiswa padivi revoltage bhazi reiyo dry-type transformer.
