Abstract

The invention discloses a testing device of a lightning stroke counter, comprising a capacitor bank, a power conversion unit, a switch unit, an input unit, a CPU and a display unit, wherein the capacitor bank is used for discharging to the lightning stroke counter; the power conversion unit is used for converting an input current into a current for charging the capacitor bank; the switch unit is connected with the power conversion unit and the capacitor bank and used for switching on or off the charging current of the power conversion unit to the capacitor bank; the input unit is used for inputting an operational instruction of a user; the CPU is used for receiving an input signal of the input unit and controlling the current conversion of the power conversion unit and the on-off of the switch unit; and the display unit is used for displaying the output of the CPU. The invention can realize continuous and automatic test according to man-made testing frequency, greatly facilitates and simplifies the testing operation process, reduces the workload and saves the testing time.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for a lightning strike counter. Background technique [0002] Surge arresters are important overvoltage protection devices in substations, which can effectively protect equipment insulation from damage. When the power grid is subjected to lightning overvoltage or operating overvoltage and reaches the specified voltage limit, the arrester will act to release the overvoltage load, and limit the overvoltage caused by lightning to the level that the insulating equipment can withstand, thereby protecting the insulation of the equipment. effect. [0003] In order to judge whether the arrester is activated by overvoltage and record the number of actions, the prior art usually uses a discharge counter for arresters, commonly known as a lightning strike counter, to record the number of actions, so as to understand the operation of the arrester and analyze related accidents. [0004] The li...
