Abstract

The invention discloses a method for preparing a no-local-discharge compound-glass fiber winding pipe. The preparation method comprises the following steps of: coating a release agent on the surface of a core module; arranging the core module on a numerical-control winding machine; automatically completing a winding process controlled by a microcomputer; winding fiber or alkali-free Worland clothes on the core module; preparing a resin adhesive, wherein the resin adhesive comprises epoxide resin, a curing agent, a toughener, silicon dioxide and a defoaming agent; injecting the resin adhesive in vacuum, stopping injecting the resin adhesive, closing a valve ladder and heating for solidifying and molding. The polymeric housed arrester has simple structure, light weight, good toughness, strong shock resistance capability, high tensile strength, high bending resistance, high twist resistance and more precise fiber distribution and is widely used for a power electric network, a transformer station and a communication device.

Description

technical field [0001] The invention relates to a lightning arrester used in power grids, substations, and communication equipment, in particular to a composite jacket lightning arrester and a method for preparing a non-partial discharge composite glass fiber winding pipe. Background technique [0002] Surge arresters are important components for protecting electrical equipment. When the power equipment or power facilities are impacted by instantaneous large currents such as lightning and overvoltage during live operation, the arrester is at this time to play a certain role in buffering and absorbing the energy generated by the instantaneous high current, so that the power equipment and facilities will not be damaged. . The existing porcelain-sleeved zinc oxide arrester has the following defects: [0003] a. Because most of the products use porcelain jacket arresters, if the arrester is damaged, the arrester will explode, endangering the safety of surrounding personnel and...
