Abstract

The invention discloses a lightning stroke counter testing device and method. The lightning stroke counter test device comprises a power supply module, a control module, a first switch, a high-voltage generation module, a relay and a test contact. The control module is used for controlling the first switch to be switched on every first preset time according to preset times; the power module is used for charging the high-voltage generation module when the first switch is switched on; the control module is further used for controlling the first switch to be switched off and controlling the relay to be switched on when the charging time of the high-voltage generation module reaches second preset time; and the high-voltage generation module is used for discharging to the lightning stroke counter through the relay and the test contact when the relay is switched on so as to judge whether the recording frequency of the lightning stroke counter conforms to the preset frequency or not. According to the technical scheme, the accuracy of testing the lightning stroke counter is improved, the testing time is saved, and the testing efficiency is improved.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of testing, and in particular to a lightning strike counter testing device and method. Background technique

[0002] Surge arresters are widely used in power systems, and the quality of the arrester itself is related to the operation safety of the entire power grid. The main internal components of the arrester will gradually deteriorate due to long-term exposure to voltage, and most of the arresters exposed outdoors are also susceptible to moisture, which will further aggravate the The deterioration speed will cause an explosion in serious cases. Therefore, it is necessary to use the lightning strike counter to monitor the discharge times of the arrester. When the discharge times of the arrester reach the upper limit, the arrester can be replaced in time.

[0003] When the lightning strike counter is working, the count may be inaccurate, which affects the accuracy of the arrester mo...
