AI Technical Summary
The low thermal conductivity of insulation materials in existing ultra-high voltage power equipment leads to poor heat dissipation, which can easily cause accelerated aging of insulation and discharge breakdown.
A heat transfer channel is formed by staggered semi-cylindrical or semi-circular strip grooves on the upper and lower surfaces of the gasket body. The shape and size of the insulating flat gasket structure are optimized to improve heat dissipation.
It significantly improves the heat dissipation effect of insulation materials and reduces the risk of insulation aging and discharge breakdown.

[0020] Example:
[0021] This utility model provides a venting and insulating flat washer. Before designing and manufacturing, a large number of existing insulating products were collected and tested to create a special structure and shape tailored to the characteristics of the insulating material. Without affecting the strength of the insulating product, a slotted design is incorporated into the insulator to solve the venting and heat dissipation problem. Figure 1 and Figure 2 As shown, the insulator is a gasket body 1. Grooves 2 are provided on both the upper and lower surfaces of the gasket body 1. The grooves 2 connect the inner and outer rings of the gasket body 1, providing a heat transfer channel between the inside and outside of the gasket body 1, while reducing the impact on the insulation of the gasket body 1.
[0022] In this embodiment, the grooves 2 on the upper and lower surfaces of the washer body 1 are staggered in the vertical direction to avoid overlapping and causing some parts of the washer body 1 to be too thin, thereby reducing the impact on the insulation effect. At the same time, the grooves 2 are semi-cylindrical. The diameter of the washer body 1 is 40mm and the inner diameter is 17mm, so the grooves 2 are grooves with a radius of 1mm and a depth of 0.5mm.
[0023] In other embodiments, such as Figure 3 As shown, the groove 2 is semi-circular and the path of the groove 2 is arc-shaped. During the manufacturing process, an elliptical cylinder is used to form a protrusion in the mold, so that the adjacent grooves 2 on the washer body 1 form two sides of an ellipse, which increases the torsional bearing capacity of the washer body 1 and also dissipates heat.
[0024] This design takes into account the characteristics of insulating materials and optimizes and innovates the shape, size and arrangement of the insulating flat gasket structure in three dimensions. The heat dissipation effect of the slotted insulating flat gasket is significantly better than that of ordinary gaskets.
[0025] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
