Abstract
The utility model relates to a cushion block of a dry-type transformer. The cushion block is provided with a cushion block body. A protruding block is arranged on the cushion block body, the protruding block and the cushion block body are integrally formed, the upper portion of the protruding block is provided with two strip holes directly leading to the cushion block body, the two strip holes are a first strip hole and a second strip hole, and two grooves distributed symmetrically and directly leading to the protruding block are formed in the two ends of the upper surface of the cushion block body in the direction vertical to the protruding block. The cushion block is manufactured by unsaturated polyester glass fiber reinforcement molding compound, heated and melted in a die, and then cooled and solidified to be formed. The cushion block is high in mechanical strength, good in electrical performance and easy to manufacture, achieves compression molding forming, has a smooth surface without burrs, and does not influence local discharging of the transformer.
Description
Technical field
The utility model relates to the technical field of transformer, especially a kind of dry-type transformer cushion block.
Background technology
Cushion block is the vitals that dry-type transformer coil supports, and in order to guarantee that dry-type transformer moves reliably and with long-term, must meet the basic demand of the aspects such as electrical strength and mechanical strength.Yet the cushion block height using on existing dry-type transformer is limited, so high-tension coil is easily creepage along cushion block, causes the electric discharge to parts such as folders.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the problem proposing in above-mentioned background technology, the utility model provides a kind of dry-type transformer cushion block, and its mechanical strength is high, good electric property, and do not affect the partial discharge of transformer.
The utility model solves the technical scheme that its technical problem adopts: a kind of dry-type transformer cushion block, there is cushion block body, on cushion block body, be provided with and the integrated projection of cushion block body, the top of projection offers two and leads directly to the strip hole to cushion block body, they are respectively the first strip hole and the second strip hole, the two ends of cushion block body upper surface and with the perpendicular direction of projection on offer that twice are symmetrical to be led directly to the groove to projection.
Limit further, the length of the first strip hole is less than the length of the second strip hole.
Limit further, projection cross section is inner concavity.
The beneficial effects of the utility model: two grooves that the upper surface of dry-type transformer cushion block of the present utility model is offered can be used for placing silicagel pad or strengthen cushion block, two strip holes that projection top is offered can conveniently separate high-voltage coil and low-voltage coil, to reach the insulation between high-voltage coil and low-voltage coil.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
In figure 1, cushion block body, 2, projection, 3, strip hole, 3-1, the first strip hole, 3-2, the second strip hole, 4, groove.
Embodiment
Dry-type transformer cushion block as shown in Figure 1, there is cushion block body 1, on cushion block body 1, be provided with and the integrated projection 2 of cushion block body 1, the top of projection 2 offers two and leads directly to the strip hole 3 to cushion block body 1, they are respectively the first strip hole 3-1 and the second strip hole 3-2, the two ends of cushion block body 1 upper surface and with the perpendicular direction of projection 2 on offer that twice are symmetrical to be led directly to the groove 4 to projection 2.
Wherein the length of the first strip hole 3-1 is less than the length of the second strip hole 3-2.Projection 2 cross sections are inner concavity.
Claims (3)
