Abstract

The invention discloses a zinc oxide arrester whose controllable part adopts a small-diameter valve plate, comprising a fixed part and a controllable part, and is characterized in that one end of the controllable part is connected with the gas gap unit, and the other end is connected with one end of the fixed part , both the fixed part and the controllable part contain at least one layer of arrester valve plates, the multilayer arrester valve plates are connected in series, and the diameter of the arrester valve plate of the fixed part is larger than that of the controllable part. The invention has a simple structure, can reduce the charge rate, improve the service life of the arrester, and achieve the goal of enhancing the ability to limit the overvoltage of the lightning when the lightning voltage comes.

Description

technical field [0001] The invention belongs to the technical field of surge arresters, and in particular relates to a zinc oxide surge arrester whose controllable part adopts a small-diameter valve plate. Background technique [0002] The interior of the conventional zinc oxide arrester is a multi-layer zinc oxide valve plate of the same model and the same specification in series. If you want to control or test the performance of the arrester valve, you must connect the two ends of the valve in parallel, which will inevitably increase the diameter of the arrester, that is, change the specifications of the original arrester. From the electrical analysis, this will inevitably affect the distributed capacitance of the original arrester valve, and further affect the voltage distribution and other parameters under the normal operation of the arrester. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a zinc oxide arres...
