Problems solved by technology

[0003] At present, there are many kinds of counters on the market, and the quality is also uneven. Most of the manufacturers do not provide professional testing equipment, generally only provide simple testing methods, and on-site diagnosis is very difficult.
Especially for the general testing equipment currently on the market, when doing the counter action test, it does not use the lower limit action current value of the detection counter, and the output waveform is not an 8 / 20 waveform, which causes each time the counter counts. When the counter voltage is high, the counter moves once, and at this time the pointer of the counter ammeter is at the bottom of the range, which will damage the counter and affect the arrester.

Abstract

The invention relates to the technical field of power industry equipment, and in particular to an arrester discharge counter tester and a detecting device. The arrester discharge counter tester comprises an insulating rod, a high-voltage component and a hook body suspended from an arrester. The top of the insulating rod is connected to the hook body. The bottom end of the insulating rod is connected to the high-voltage component. The high-voltage component comprises a high-voltage generator, a main switch, a button and a jack. The button is provided with at least two shifts to output differentlevels of voltage. The jack is used for charging or grounding. The hook body comprises a main body and a connecting member. The main body is bent into a hook-like structure. The main body is connected to the insulating rod through the connecting member. The detecting device includes the arrester discharge counter tester.

Description

technical field [0001] The invention relates to the technical field of electric power industry equipment, in particular to a lightning arrester discharge counter tester and a detection device. Background technique [0002] At present, counters for lightning arresters have been popularized in various large and small substations in my country, providing important data for the reliable operation of lightning arresters. When the counter of the arrester in operation displays abnormal data, the staff needs to carry out corresponding inspections to find out the cause of the failure. First, when the number of actions of the counter technical meter does not move or jumps, it is generally because the gears inside the counter meter are corroded or damaged. Second, when the value of the counter ammeter is significantly larger than normal, it is generally because the continuous current of the arrester increases or There is a malfunction in the counter measurement section. Third, when t...
