Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The arrangement of a kind of power transformer side outlet of the utility model, comprising the fixing of high-pressure side bushing with (shown in Fig. 1), the design of high-pressure side shell and the layout of installation (shown in Fig. 1), high voltage side current instrument transformer and installation (Fig. 2,3,4 shown) are installed.
High voltage side current instrument transformer 16 is arranged in current transformer measurement mechanism 8, and because side, high-pressure side outlet 14 is drawn, corresponding current transformer 16 is also installed by the level of routine and changed at right angle setting into.Consider that current transformer 16 is due to the impact by gravity, inside current transformer measurement mechanism 8, welding supports work durm 12, uses insulating board reinforced insulation between current transformer 16 inwall side and support work durm 12; And insulated by insulating paper cylinder 15 between side, high-pressure side outlet 14 and support work durm 12; Clamped by the positioning screw 13 of laminated wood 11 and corner, fixed current instrument transformer 16.In oil tank of transformer 3 side, installation method orchid 9 measured by corresponding side, high-pressure side outlet 14 position welding current instrument transformer, makes current transformer measurement mechanism 8 end flange be fixed on fuel tank 3 side with the current transformer measurement mechanism flange 9 being welded on side, high-pressure side outlet 14 position, fuel tank 3 side by bolt; Current transformer measurement mechanism 8 other end flange and bushing base flange 7 are bolted fixing, thus make bushing 5 level be arranged on oil tank of transformer 3 side; Because bushing 5 level is installed, gravity is very large on the impact of bushing 5, the impact not alleviating gravity can cause bottom bushing 5 and occur oil seepage phenomena between bushing base flange 7 flange face, by increasing insulating support 4, insulating support 4 one end is fixed on high-pressure side shell 1, the other end is connected to bushing 5 and lifts one's head place, the impact of gravity on bushing 5 is alleviated by the pulling force of insulating support 4, increase cable clamp 6 at high-pressure side shell 1 place inside place, alleviate the pulling force of inlet wire cable to bushing 5.
At whole high-voltage side outlet wire peripheral disposition high-pressure side shell 1, the size of high-pressure side shell 1 is accomplished minimum as far as possible when meeting electric insulation distance, be conducive to like this saving space, increase high-pressure side shell 1 strengthened by support iron support 2 intensity as the strong point at the bottom position place of high-pressure side shell 1, alleviate the impact of gravity on high-pressure side shell 1.
Specifically, the at right angle setting of original conventional products bushing is changed into level and installs by the utility model, and the leakage of oil that will solve when bushing 5 level is installed and problems of mechanical strength.Because side, high-pressure side outlet 14 is drawn from the side, current transformer 16 is also installed by level thereupon and has been changed at right angle setting into, needs the clamping of current transformer 16 during solution at right angle setting, fixation problem.Be equipped with high-pressure side shell 1 in outside, high-pressure side, high-pressure side shell 1 size is accomplished minimum as far as possible when meeting insulation distance, is conducive to reducing cost and the weight of self.
Secondly, transformer high-voltage side terminal lead-out wire is drawn from fuel tank side.At side, high-pressure side outlet 14 position, fuel tank side welding bushing base flange 7, make its bushing 5 level can be arranged on oil tank of transformer 3 side; Due to the impact by gravity, bushing 5 mechanical strength weakens, and takes the method increasing insulating support to strengthen the intensity of bushing; Insulating support one is connected with bushing head, and one is fixed on high-pressure side shell 1 place; Enhanced the intensity of bushing 5 by the pulling force of insulating support 4, alleviate the impact of gravity on bushing 5, leakage of oil when bushing 5 level is installed and problems of mechanical strength are solved (Fig. 1 is shown in by schematic diagram).
Because side, high-pressure side outlet 14 is drawn, corresponding current transformer 16 is also installed by original level and is changed at right angle setting into, due to the impact by gravity, clamping and fixation problem particularly outstanding, the method solved is that welding supports work durm 12 inside current transformer measurement mechanism 8, uses insulating board reinforced insulation between current transformer 16 inwall side and support work durm 12; And insulated by phenolic aldehyde paper web between side, high-pressure side outlet 14 and support work durm 12; Clamped by the positioning screw 13 of laminated wood 11 and corner, fixed current instrument transformer (schematic diagram is shown in Fig. 2, Fig. 3, Fig. 4).
The high-pressure side shell 1 of periphery, high-pressure side reduces volume when meeting insulation distance as far as possible, and the mechanical strength of high-pressure side shell 1 is strengthened by support iron support 2 in bottom.In high-pressure side shell 1, correct position place is welded and fixed the cable clamp 6 of service cable, alleviates the pulling force (schematic diagram be shown in Fig. 1) of cable to bushing 5.
