Problems solved by technology

In order to ensure the continuous use of electricity by residents and meet the reliability requirements of power supply, it is necessary to reduce the number of power outages and power outage time as much as possible; however, the workload is too large when live work is used, resulting in failure to complete the detection of lightning arresters in the operation of the distribution network as required
In the season of frequent thunderstorms, tripping of distribution lines due to lightning arrester failures occurs frequently, which affects the safe and stable operation of distribution lines

Abstract

The invention puts forward a lightning arrester capable of being dismounted on a live line. The lightning arrester comprises a silicone rubber insulator support rack which comprises a silicone rubber insulator; an upper end and a lower end of the silicone rubber insulator are respectively provided with a first support cross bar and a second support cross bar that are made of metal material and arranged perpendicular to a length direction of the silicone rubber insulator; an upper part of one end, connected with the silicone rubber insulator, of the first support cross bar is provided with a first fixing screw bolt; a lower part of one end, connected with the silicone rubber insulator, of the second support cross bar is provided with a second fixing screw bolt; the other end of the first support cross bar and the other end of the second support cross bar are provided with grooves that are respectively a first groove and a second groove; elastic cards are respectively connected in the first groove and the second groove, and the elastic cards are respectively connected with two ends of the lightning arrester in a clamped manner. The lightning arrester capable of being dismounted on the live line can be mounted and dismounted on the live line, and the lightning arrester is enabled to be convenient to test and change.

Description

technical field [0001] The invention relates to the electrical field, in particular to a lightning arrester that can be assembled and disassembled while charging. Background technique [0002] In the power system, according to the relevant operation and use regulations of power equipment, the arrester operating in the distribution network needs to be tested once every 1 to 3 years, and a test should be carried out before the thunderstorm season. [0003] To detect the arrester in operation, it is necessary to remove the arrester. Since the equipment is charged and the arrester is fixed by bolts, the arrester in operation can only be removed through power failure or live work. In order to ensure the continuous use of electricity by residents and meet the reliability requirements of power supply, it is necessary to reduce the number of power outages and power outage time as much as possible; however, the workload of live work is too large, resulting in failure to complete the ...
