Kubva kuma1990, nyika yangu yakaunza American box-type substation, uye chimiro chekuchinja kwekutakura, ring network switch uye fuse yakave yakareruka mutransformer mafuta tank uye yakanyudzwa mumafuta.Anosunga zvakare anotora mafuta-akanyudzwa zinc oxide arrester.Iyo transformer inodzima piro yemafuta, uye tangi yemafuta uye radiator zvinoratidzwa kumhepo.Mhando yekuchinja kwebhokisi iyi inonzi American box change, inofananidzwa nebhokisi rakarembera pedyo netransformer.Panyaya yehuwandu, European-style box-type transformers yakakura nekuda kwekuiswa kwemukati kweajairika switch makabati uye transformers.Iyo American box-type transformer ine vhoriyamu diki nekuda kwekuiswa kwakabatanidzwa.Panyaya yekudzivirira, iyo yakakwira-voltage yeEuropean box transformer inodzivirirwa nemutoro wekuchinja uye ikozvino-inogadzirisa fuse.Kana iyo-fase-phase fuse ichivhuvhuta, shandisa anorova fuse kuti avhure matatu-phase mutoro switch panguva imwe chete kuti udzivise kushaikwa kwechikamu, uye chinja chemutoro chinodiwa kuve nekugona kugura uye kutumira ikozvino.Rutivi rwepasi-voltage runodzivirirwa nekuchinja kwekutakura uye ikozvino-kumisa fuse, uye rutivi rwepamusoro-voltage yeAmerican box transformer inodzivirirwa nefuse, nepo kushandura kwekutakura kunongova nebasa rekushandura nekucheka kwepamusoro. -voltage mutoro ikozvino, uye kukwanisa idiki.Kana fuse yechikamu padivi repamusoro-voltage ichiridzwa, voltage padivi-yakadzika-voltage inodzikira, uye iyo under-voltage dziviriro kana pamusoro-ikozvino kudzivirira kwepurasitiki kesi otomatiki air switch ichaita, uye yakaderera-voltage mashandiro. hazvizoitiki.Kubva pamaonero emutengo wechigadzirwa, mutengo weEuropean-style mabhokisi wakakwira.Kubva pakuona kwenzvimbo yekudzikisa mutengo wechigadzirwa, kuchine nzvimbo yakakura yekudzikisa mutengo yeAmerican box transformers.Kune rumwe rutivi, matatu-chikamu cheshanu-column iron core yeAmerican box transformer inogona kushandurwa kuita matatu-chikamu chetatu-column iron core.Kune rumwe rutivi, iyo yakakwirira-voltage chikamu cheAmerican box transformer inogona kuchinjwa kubva The transformer mafuta tank inotamirwa kune kunze kwetangi yemafuta, inotora nzvimbo yekamuri yepamusoro-voltage.
