Embodiment Construction

[0039] The application provides a method for dehumidifying the surface of the discharge counter, which is used to remove rain or frost on the surface of the discharge counter, so as to check the number of lightning strikes recorded by the discharge counter. figure 1 For the flow chart of the application discharge counter surface dehumidification method, such as figure 1 The method for dehumidifying the surface of the discharge counter specifically includes the following steps.

[0040] Step S1000: Detect the temperature T and relative humidity RH on the surface of the discharge counter.

[0041] Step S2000: Determine whether the surface temperature T of the discharge counter is higher than a preset freezing temperature. It should be noted that for different regions or climate conditions, those skilled in the art can set an appropriate freezing temperature according to local actual conditions or needs, for example, in this example, the freezing temperature is set to 0°C.

Abstract

This application discloses a method and device for dehumidifying the surface of a discharge counter. By detecting the temperature and relative humidity of the surface of the discharge counter, and according to the temperature and relative humidity of the surface of the discharge counter, it is estimated whether there is rain or frost in the dehumidification of the surface of the discharge counter. When it is judged that there is rain, dew or frost on the surface of the discharge counter, start the fan, and the wind provided by the fan to the surface of the discharge counter is detected. The problem with looking at the number of lightning strikes recorded by the discharge counter. The realization process of the surface dehumidification method of the discharge counter of the present application is easy and quick, and the composition and structure of the device are simple, which is easy to be popularized and used widely.

Description

technical field [0001] The application relates to the technical field of lightning arresters, in particular to a method and device for dehumidifying the surface of a discharge counter. Background technique [0002] The discharge counter is connected to the arrester and is used to record the number of arrester actions, grasp the law of lightning activities, continuously improve the reliability of lightning protection protection for power transmission and distribution equipment, monitor the life of the arrester and study the operation of the power system under the action of atmospheric overvoltage. of electrical equipment. [0003] During the daily inspection process, the number of lightning strikes on a certain phase of a certain line can be judged by checking the number of lightning strikes displayed by the discharge counter installed on a certain phase of the transmission line, so as to provide a reference for the differential lightning protection work of transmission lines...
