Insulation pipe type busbar three-layer coextrusion continuous vulcanization production equipment and production process

Abstract

The invention discloses insulation pipe type busbar three-layer coextrusion continuous vulcanization production equipment and a production process. The equipment comprises a conductor pipe connecting auxiliary pushing car, a conductor pipe connecting platform, conductor pipe connecting pins, an air-pressure track pusher, a three-layer coextrusion machine head, an upper closer, a vulcanization pipe, a cooler, a lower closer, an air-pressure pressing device, an insulation stripping cutter and a stripping cutting platform positioned on the same inclined surface from high to low in sequence. The production process comprises the following steps: single conductor pipes are connected continuously by the connecting pins to satisfy the continuous extrusion and continuous vulcanization technical requirements; a production line is aslant arranged to eliminate the gravity dropping influence of the conductor pipes for free insulation vulcanization; the pressing device is used for eliminating aslant downward sliding force of the conductor pipes and improving the extrusion stability; and the scheme satisfies the continuous extrusion and continuous vulcanization production requirements of high-voltage-grade insulation pipe type busbars.

Description

technical field [0001] The invention relates to a three-layer co-extrusion continuous vulcanization production equipment and a production process of an insulating tubular busbar. Background technique [0002] Insulated tubular busbars are widely used in the field of power transmission because of their large carrying capacity and low skin effect. However, the conductor tube is a hard conductor, and the short length of a single conductor tube restricts its The bottleneck of the development of insulation technology; after searching the existing technology, it is found that there is no production equipment and production process for the production of insulating tubular busbars by continuous extrusion and continuous vulcanization. In order to improve the withstand voltage level of insulating tubular busbars and improve the product performance, there is an urgent need to develop a three-layer co-extrusion continuous vulcanization production equipment and production process for ins...
