Problems solved by technology

Usually, the high-voltage hollow insulators used outdoors are generally porcelain insulators. Because porcelain insulators have poor pollution flashover resistance, are heavy, easy to break, and need to be cleaned regularly, it brings a lot of inconvenience to installation and use.
Due to the limitation of production conditions of the existing composite insulators, the umbrella body is generally formed by bonding several sheds to form a whole. Since the composite insulator is generally installed outdoors, after a long time of use, the joint of two adjacent sheds will It is prone to cracks, which affects the overall performance, so it is necessary to develop new composite insulators to meet the needs of actual production and use

Embodiment Construction

[0011] With reference to the accompanying drawings, the present invention is composed of a flange 1, an insulating cylinder 2, and an umbrella body 3. The insulating cylinder 2 is a hollow tube made by winding epoxy glass fibers. An integral umbrella body 3 is arranged outside the insulating cylinder 2. The body 3 is formed by injection of high-temperature vulcanized silicone rubber, and its heating temperature is 150°C-190°C, and the heating temperature in this embodiment is 155°C. The two ends of the insulating cylinder 2 are glued to the flange 1 with an adhesive.

Abstract

The invention relates to a composite insulator used in high voltage electrical apparatus of electric industry and its manufacture method, comprising Frange, insulating tube and umbrella. The insulating tube is hollow pipe wrapped by epoxy glass fiber, a umbrella is out of it and the frange is on the two sides of insulating tube, theumbrella is a integration injected by high-temperature silicon sulfide rubber, which making the performance much more stable, and working temperature is controlled within a certain range which makes inner tissue of umbrella after sulfuration more symmetrical.

Description

technical field [0001] The invention relates to a composite insulator for high-voltage electrical appliances in the electric power industry and a production method thereof. Background technique [0002] After retrieving relevant patent documents, no composite insulator with the same structure as the present invention and its production method have been retrieved yet. Usually, the high-voltage hollow insulators used outdoors are usually porcelain insulators. Because porcelain insulators have poor pollution flashover resistance, are heavy, easy to break, and need to be cleaned regularly, it brings a lot of inconvenience to installation and use. Due to the limitation of production conditions of the existing composite insulators, the umbrella body is generally formed by bonding several sheds to form a whole. Since the composite insulator is generally installed outdoors, after a long time of use, the joint of two adjacent sheds will be damaged. It is prone to cracks, which affec...
