Abstract

The invention discloses a 10 kV/380 V combined pole distribution line lightning-proof apparatus. A 10 kV/380 V combined pole distribution line comprises one loop of three-phase 10 kV line above a straight pole and one loop of four-phase 380 V low-voltage line below the straight pole, a line arrester is mounted at any phase of the three-phase 10 kV line, a lightning-proof line support and a lightning-proof line are mounted at the top of a base pole, a ground downlead and a ground part connected to the lightning-proof line support and the line arrester on a cross arm of the 10 kV line are mounted on the base pole. The 10 kV/380 V combined pole distribution line lightning-proof apparatus has the advantages that modifying cost and operation and maintenance workload are decreased, lightning trip-out rate of the 10 kV/380 V combined pole distribution line is greatly decreased, and economic benefit is increased.

Description

technical field [0001] The invention relates to a line lightning protection device, in particular to a 10kV / 380V combined pole power distribution line lightning protection device. Background technique [0002] In the city, due to the limited corridors of power lines, in fact, there are often lines with two or more voltage levels that need to occupy one side of the road. Generally, the method of increasing the height of the pole and erecting wires in multiple layers is used to solve the problem. Among the medium-voltage overhead distribution lines, the most commonly used is the combined pole line, that is, the distribution lines with different voltage levels and multiple parallel poles. Previous papers and patents proposed lightning protection methods for single-circuit and multi-circuit 10kV distribution lines on the same tower, such as the invention patent "A Method for Preventing Lightning Breakage of 10kV Overhead Insulated Lines" (authorization number: CN 102290775 B );...
