Abstract
The utility model discloses a high-voltage casting body of a transformer. The high-voltage casting body comprises a high-voltage casting body (1), wherein two main tap joints (2) and a group of tap joints (3) are arranged on the tapping side of the high-voltage casting body (1), and bulges (1.1) are arranged at the parts of the high-voltage casting body (1), where the main tap joints (2) and the tap joints (3) are mounted. The high-voltage casting body of the transformer saves casting materials, increases the creepage distance between the main tap joints and the tap joints and the insulation distance between a tap nut and a high-voltage coil, and improves the safety performance of the transformer.
Description
Technical field:
The utility model relates to the transformer technology field, specifically is a kind of high pressure pour mass of transformer.
Background technology:
The high pressure pour mass of transformer is wrapped in the periphery of high-tension coil, be under vacuum state with poured with epoxy resin outside high-tension coil.In order to reach insulation distance and the insulation distance between principal tapping and the tap between branch connected nut and the high-tension coil, tap one side of high pressure pour mass needs to raise, to increase creepage distance.But, so directly cause the waste of mould material, and coil being big more, its material that needs is just many more, wastes big more.
The utility model content
The technical problem that the utility model will solve is; Provide a kind of and practice thrift mould material, increase the creepage distance between principal tapping and the tap and divide the insulation distance between connected nut and the high-tension coil, improve the high pressure pour mass of the transformer of transformer security performance.
The technical scheme of the utility model is; A kind of high pressure pour mass with transformer of following structure is provided; Comprise high pressure cast body; Said high pressure cast body tap one side is provided with two principal tappings and a set of taps, and the position that said high pressure cast body is installed principal tapping and tap is equipped with convexity.
The cross section of said convexity is rectangular.
After adopting said structure; The utility model compared with prior art; Have the following advantages: be equipped with convexity because said high pressure cast body is installed the position of principal tapping and tap, can increase the creepage distance between principal tapping and the tap like this and divide the insulation distance between connected nut and the high-tension coil, saved the original whole structure that raises; Can save mould material like this, also can improve the security performance of transformer simultaneously.
Description of drawings
Accompanying drawing 1 is the sketch map of high pressure pour mass of the transformer of the utility model.
Accompanying drawing 2 is schematic side view of high pressure pour mass of the transformer of the utility model.
Shown in the figure, 1, high pressure cast body, 1.1, convexity, 2, principal tapping, 3, tap.
Embodiment
Be described further below in conjunction with the high pressure pour mass of accompanying drawing the transformer of the utility model.
Like Fig. 1, shown in Figure 2; The high pressure pour mass of the transformer of the utility model; Comprise high pressure cast body 1, said high pressure cast body 1 tap one side is provided with two principal tappings 2 and a set of taps 3, and the position that said high pressure cast body 1 is installed principal tapping 2 and tap 3 is equipped with protruding 1.1; That is to say that two principal tappings 2 are installed on the corresponding convexity 1.1, a set of taps 3 is installed on the corresponding convexity 1.1.
Said protruding 1.1 cross section is rectangular.
Claims (2)
1. the high pressure pour mass of a transformer; Comprise high pressure cast body (1); Said high pressure cast body (1) tap one side is provided with two principal tappings (2) and a set of taps (3), and it is characterized in that: the position that said high pressure cast body (1) is installed principal tapping (2) and tap (3) is equipped with convexity (1.1).
2. the high pressure pour mass of transformer according to claim 1, it is characterized in that: the cross section of said convexity (1.1) is rectangular.
