Abstract

The invention discloses an insulating supporting bar for a high-voltage electrical appliance and a production method thereof. The insulating supporting rod for the high-voltage electrical appliance comprises an epoxy resin rod body and two metal inserts, wherein the two metal inserts are respectively embedded in two ends of the epoxy resin rod body; the upper end surface and the lower end surface of the epoxy resin rod body are parallel; an included angle between the central connecting line of the upper end surface and the lower end surface and the vertical line of the end surfaces is 0-15 degrees; and internal threads are arranged on the metal inserts. The production method of the insulating supporting rod comprises the following steps: a. coating a semi-conductive rubber layer outside the two metal inserts; b. fixing the two metal inserts in a mould; c. vacuum-pouring epoxy resin; and d. demoulding. The epoxy resin rod body can be installed and used in a tiny space, and has high structural strength; and the supporting rod produced by the invention has high structural strength and good insulating property.

Description

technical field [0001] The invention relates to an insulating support rod and a production method thereof, in particular to an insulating support rod for high-voltage electrical appliances and a production method thereof. Background technique [0002] Traditional insulating support rods are mainly made of ceramics or glass (an insulating material). In the field of high-voltage electrical insulation technology, insulating support rods as insulating components, that is, components made of ceramics or glass bear mechanical loads. , and bear the electrical load, as the voltage level increases, the electromechanical load that the insulating support rod needs to bear continues to increase, and in SF 6 With the continuous improvement of the internal bearing of the gas, the inherent defects of the porcelain or glass insulating support rods are exposed in use. The main manifestations are: low insulation performance under dirty conditions, low surface flashover voltage; mechanical st...
