Abstract
The utility model discloses a plate structure without static electricity at the end of transformer high-voltage winding, comprising backing strips, angle rings, supplementary insulation, thick-turn windings, etc. The utility model is suitable for transformer pie winding whose end voltage is 60-110KV. Since the static plate at the winding end is saved, the winding construction is simplified, working hours and materials are saved, and cost is lowered. The utility model has the advantages of simple structure, easy manufacture and reliable electric property.
Description
The utility model belongs to transformer ' s type, is that a kind of transformer high voltage winding overhang does not have the static board structure, is applicable to that anode-cathode voltage is the pie winding transformer of 60～110KV.
At present, traditional high voltage transformer, anode-cathode voltage are 60～110KV, and all must there be static board the end of its pie winding.The effect of static board is to reduce the winding overhang electric field, and protection end line segment is to improve the electrical strength of winding.But the static board structure is comparatively complicated, the technological requirement height, as fruit structure incorrect or process coarse, not only static board do not have the effect of protection line segment, itself will become on the contrary insulation weakness.In addition, because the static board structure is comparatively complicated, manufacturing procedure is more, manufacturing expenses man-hours, processing cost height.
The purpose of this utility model aims to provide a kind of no static board winding construction, takes the reinforced insulation measure on line segment, not influencing winding overhang under the preceding topic of iron yoke distance, satisfies the electric property of winding.Owing to cancelled static board, simplified winding construction, can save man-hour, economical with materials reduces cost.
The utility model is to realize with following technical scheme: 1, increase the insulation of winding overhang line segment, to reduce the electric field strength of end line segment, main by increasing the turn insulation of end line segment lead, it is thick turn insulation, or adopt and wrap supplementary insulation, the lead that is line segment is identical with the normal reach turn insulation, adds the bag insulation at whole line segment, is referred to as supplementary insulation; 2, place square ring at the end line segment, square ring can be a soft corner-ring, also can be the forming angle ring, external diameter both sides or a side in square ring is placed on; 3, place filler strip at the end line segment, filler strip is placed on the inside and outside footpath two or a side of line segment.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.
Fig. 1～8th, the structural representation of the utility model embodiment.
Describe concrete structure of the present utility model in detail in conjunction with Fig. 1～8.
Structure of the present utility model is by filler strip 1, square ring 2, and supplementary insulation 4, thick turn insulation winding 3 constitutes, wherein:
A, according to Fig. 1, inside and outside the footpath of winding 5, be sidelong and put square ring 2, filler strip 1 is installed with in square ring 2 sides, its winding is thick circle winding 3;
B, according to Fig. 2, outside winding 5 on additional 2 sides of bag, its interior external diameter both sides at supplementary insulation 4 are installed with square ring 2, filler strip 1 is installed with in square ring 2 sides;
C, according to Fig. 3, be installed with square ring 2 in the inboard, footpath of winding 5, filler strip 1 is installed with in square ring 2 sides, the footpath of winding 5 outside is thick circle winding 3;
D, according to Fig. 4, outsourcing supplementary insulation 4 on winding 5, the inboard, footpath of winding 5 is installed with square ring 2, filler strip 1 is installed with in square ring 2 sides;
E, according to Fig. 5, in the footpath of winding 5, the outside is installed with square ring 2, winding is thick circle winding 3;
F, according to figure b, outsourcing supplementary insulation 4 on winding 5, its footpath in, the outside is installed with square ring 2; G, according to Fig. 7, be installed with square ring 2 in the inboard, footpath of winding 5, winding is thick circle winding 3;
H, according to Fig. 8, outsourcing supplementary insulation 4 on winding 5, its footpath inboard be installed with square ring 2.
The utlity model has simple in structure, easily manufactured, the reliable characteristics of electric property. Owing to cancelled static board, simplify the structure, economical with materials reduces cost.
