Pano, SPL, fekitori yeChina inoshandura, inokupa chirevo pamusoro pekudzivirira kwekufambisa kwemafuta akanyudzwa. Pane 3 mikuru yekuchengetedza michina:

1, gasi relay: inoshandiswa 800kVA uye pamusoro pemafuta-akanyudzwa transformer. Kana iyo yekubata gasi relay yakakura kupfuura 66VA kana 15W uye kuunganidzwa kwegasi kuri 250 ~ 300ml kana mukati mechikamu chakaiswa mukumhanya kweoiri, iyo inoenderana yekubata inofanirwa kubatana. Chimiro uye nzvimbo yekuisa gasi relay inofanirwa kukwanisa kuona huwandu uye ruvara rwegasi, uye zviri nyore kutora gasi. Isa iyo ine 1.5% kuwedzera kwegradient. 220kV transformer mafuta tank cover inofanirawo kuva ne1 ~ 1.5% yakawedzera materu.

2, pressure release valve: inoshandiswa 800kVA uye pamusoro pe transformers; Kana dzvinyiriro mubhokisi remafuta yenzira yekuchengetedza mhepo kana kuti vharafu yekudzivirira inosvika 5.07 × 104Pa, inofanira kusunungurwa zvakavimbika. Mavharuvhu maviri ekuyamura mavharuvhu anofanirwa kuisirwa transformer ine 120000kVA uye pamusoro.

3, vharafu, vent plug: ese etransformer tangi madziro anofanirwa kuve nemafuta emuenzaniso valve, 110kV, 90000kVA uye 220kV, 63000kVA uye pamusoro pepakati petangi madziro anofanirawo kuva nemafuta emuenzaniso valve. 315kVA uye pamusoro pematangi achange aine mudziyo wekudhonza mvura pasi. Chikamu chezasi chetangi chetransformer chinofanirwa kunge chakakura zvakakwana chekuburitsa oiri valve, 220kV transformer inofanirawo kuva neaccine yekuburitsa mafuta. Iyo transformer inofanirwa kuburitsa gasi kana ichizadza oiri uye kuyedza, saka iyo yekumusoro chikamu che transformer pedestal, radiator, bushing, nezvimwe, inoshongedzerwa ne vent plug kuti ive nechokwadi chekuchengetedzwa kweshanduko.
