Five, embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.

Shown in Fig. 1-3, the utility model is to include fuel tank 8, case lid 11 and device body insulation 2, case lid 11 places fuel tank 8 tops, device body insulation 2 places in the fuel tank 8 of case lid 11 bottoms, transformer oil 20 is housed in the fuel tank, said fuel tank 8 outer symmetrical are equipped with

radiator

29,30, case lid 11 tops are equipped with high-voltage connection 4 and low-voltage lead 5 respectively through bushing 18 and low-tension bushing 17, said device body insulation is by height, low-voltage coil 3 is contained on the transformer core 1 of non-crystaline amorphous metal, iron-core coil has core insulation 26 in both sides up and down, cardboard 6 and phase partition 32 are arranged between high-voltage coil and low-voltage coil, and place in the fuel tank through wooden briquetting 31 and fagging 7.

In order to guarantee result of use and easy to maintenance, said case lid is equipped with boatswain chair 15 for 11 4 jiaos, and the centre has shunting switch 21, one ends that oil level indicator 19 and mercurial thermometer 27 are housed, low-tension bushing has standby sleeve pipe 16 on one side, and case lid 11 is contained in the top of fuel tank 8 by bolt 12, nut 13 and sealing offset plate 14; Bleeder plug 22 is arranged at fuel tank 8 bottoms; By high and low pressure sleeve pipe place the word board 28 of indicating A, B, C, a, b, c, o is housed on the case lid 11, with difference high-low pressure output situation (being the binding post situation), word board 24 is equipped with through rivet 25 in radiator 29 front portions, is used to indicate transformer title and correlation circumstance; For safety, earth stud 23 is housed also on the fuel tank 8.Through screw 10 nameplate 9 is housed on the said radiator 29, is used to indicate title and related parameter is arranged.

Said amorphous alloy transformer core 1 is three-phase five-limb two row rectangular arranged, and magnetic flux does not produce the structure loss of heating without the casing of fuel tank.
