Abstract

The invention discloses a 35kv/10kv common-tower distribution line lightning protection device. According to the device, the 35kv/10kv common-tower distribution line comprises a primary loop circuit three-phase 35kv line above a straight-line pole tower and a primary loop circuit three-phase 10kv line below the straight-line pole tower, line arresters are installed on any two phases of the three-phase 10kv line, a lightning conductor support and a lightning conductor are installed on the tower top of a base pole tower, a down conductor and a grounding connector are arranged on the base pole tower and are connected with the lightning conductor support and the line arrester on a cross arm of the 10kv line. The 35kv/10kv common-tower distribution line lightning protection device has the advantages of being capable of lowering improvement cost and operation maintenance load, sharply lowering lightning trip-out rate of the 35kv/10kv common-tower distribution line and improving economic benefits.

Description

technical field [0001] The invention relates to a lightning protection device for a medium-voltage power distribution line, in particular to a lightning protection device for a 35kV / 10kV combined pole power distribution line. Background technique [0002] Due to the rapid development of the domestic economy and the rising cost of land, in order to save the area occupied by line passages in cities, the method of erecting multiple distribution lines on the same pole after increasing the height of the pole tower is often adopted. A distribution line with different voltage levels and multiple parallel poles is called a combined pole line, and the 35kV / 10kV combined pole distribution line is the most common one. Previous papers and patents proposed lightning protection methods for single-circuit and multi-circuit 35kV or 10kV distribution lines on the same tower, such as the invention patent "A method for preventing lightning strike and disconnection of 10kV overhead insulated li...
