Abstract

The invention discloses a 10kV distribution network line anti-thunder protection device allowing electrified replacement. The 10kV distribution network line anti-thunder protection device allowing the electrified replacement comprises a guiding supporting plate which is connected with an insulator steel pin, an electrified separator which is connected with the guiding supporting plate, an adjusting plate which is connected with the electrified separator and an anti-thunder protector which is connected with the adjusting plate. The 10kV distribution network line anti-thunder protection device allowing the electrified replacement is formed by the guiding supporting plate, the electrified separator, the adjusting plate and the anti-thunder protector, the electrified separator is pulled to be opened to enable the anti-thunder protector and the guiding supporting plate to be separated, then the anti-thunder protector and the high-voltage insulator steel pin are separated, and electrified maintenance and replacement of the anti-thunder protector is convenient.

Description

technical field [0001] The invention relates to the technical field of lightning protection for 10kV distribution network lines, in particular to a lightning protection device for 10kV distribution network lines that can be replaced with electricity. Background technique [0002] At present, most of the domestic 10kV distribution network lightning protection devices adopt the zinc oxide arrester series air gap method, but due to the limitation of its installation structure, this type of lightning protection device has the following problems in the actual operation process: (1) After the lightning protection device is installed and operated, there is no effective detection method to judge whether the lightning protection device is good or bad, but to test its performance, the lightning protection device must be removed in a power failure state before testing; (2) According to the requirements of the power system, zinc oxide arrester products must be replaced after 5-6 years o...
