Abstract
The utility model relates to a coil cushion block, which takes the structure of a block both ends of which are provided with grooves matched with a structure on a stay, and is made of E-level insulating materials. The coil cushion block has the advantages of good toughness, high-temperature resistance, high mechanical strength, good electric performance, compression moulding forming at a time, simple structure, convenient manufacture, smooth surface without burrs, and incapability of damaging wire insulation of a coil, and is suitable for a high-voltage product and particularly a gas-insulated transformer.
Description
One, technical field
The utility model belongs to transformer manufacture technology, relates to gas-insulated transformer coil cushion block.
Two, background technology
The insulating board of making the conventional coil cushion block is the A class F insulation, can not satisfy the requirement of gas-insulated transformer.In addition, because cushion block need be from laterally inserted or taking-up on the stay, thereby require cushion block except that having certain electric property, heat resistance, mechanical performance, also want flexible, though and the present used insulating part heatproof of dry-type transformer is higher, mechanical strength still can, but electric property is relatively poor, and is immalleable, can't use.
Three, summary of the invention
The utility model solves the above-mentioned problems in the prior art exactly, provides a kind of high temperature resistant, mechanical strength height, good electric property, the coil cushion block of the gas-insulated transformer special use of good toughness.
For addressing the above problem, technical solution of the present utility model is: a kind of coil cushion block, it for two ends have with stay on the bulk of the groove that is complementary of structure, it is made by the E class F insulating material F.
The above-mentioned described end side of having a shape groove of the present utility model, the other end has platform shape groove.
Above-mentioned described making E class F insulating material F of the present utility model is an enhanced PA 66 granular solids material.
The utility model is made by the E class F insulating material F, and it is the graininess raw material, heating and melting in mould, and poach is used in cooling curing moulding more again after the depanning.Its good toughness, high temperature resistant, the mechanical strength height, good electric property, once molding formed, simple in structure, easy to make, smooth surface does not have burr, can not damage the coil wire insulation.Be applicable to the high voltage product, especially gas-insulated transformer.
Four, description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a front view of the present utility model.
Five, embodiment
As shown in Figure 1, the coil cushion block of present embodiment be two ends have with stay on the bulk 1 of the groove that is complementary of structure, it is made by enhanced PA 66 granular solids material.Use the enhanced PA 66 granular solids, melt cooling forming with mold heated.Use poach after the depanning again, to increase flexibility.Minimum thickness can be accomplished 1.5mm.The one end side of having shape groove 2, the other end has platform shape groove 3.
Claims (3)
1. coil cushion block is characterized in that: it for two ends have with stay on the bulk of the groove that is complementary of structure, it is made by the E class F insulating material F.
2. coil cushion block according to claim 1 is characterized in that: the groove that the structure with on the stay that described two ends have is complementary is: the end side of having a shape groove (2), the other end has platform shape groove (3).
3. according to claim 1 or 2 described coil cushion blocks, it is characterized in that: the E class F insulating material F of described making is an enhanced PA 66 granular solids material.
