Method for processing novel composite silicone rubber solid insulated bus

Abstract

The invention relates to a processing method of a novel composite silicone rubber solid insulated busbar. The processing method comprises the following steps: a. Pre-polish the conductive tube to be smooth without tip burrs, then wipe it clean with alcohol, and evenly apply the coupling agent on the conductive tube. On the tube, advance the oven for curve baking; b. Install the baked conductive tube on the tractor on the extruder to extrude silicone rubber. After the extrusion is completed, remove the conductive tube; c. Put the extruded tube The silicone rubber conductive tube is put into the dryer, and the temperature control is set for fluidized drying. After drying, the conductive tube is disassembled; d, making a semi-conductive layer; e, making a metal shielding layer; f, making a grounding layer; g, making a heat-shrinkable tube protective layer. The insulating bus bar of the present invention utilizes solid insulation and interface insulation to realize insulation, and does not need to be inflated at the processing site, and from the perspective of environmental protection, many cumbersome procedures are omitted.

Description

technical field [0001] The invention relates to an insulated busbar for high-voltage grades in a power system, in particular to a processing method for a novel composite silicone rubber solid insulated busbar. Background technique [0002] In recent years, with the increase of insulated bus bar manufacturers, the surface insulation performance of the bus bar has been degraded and accidents have continued. Insulated busbars are generally divided into two types according to the insulation method: 1. Gas insulated busbars; 2. Composite solid insulated busbars. Since the gas insulated busbar must be inflated on site, it needs on-site vacuuming, inflation, moisture control, leak detection and other gas treatment processes, and is affected by the installation environment, which may cause dust, conductive particles, moisture, etc. to enter the gas box, thereby affecting the busbar Its own insulation performance, which in turn affects the reliability and safety of product operation...
