Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

Abstract

The invention discloses a lightning arrester test device and a lightning arrester test system. In the test process, when a tester or a non-tester enters a lightning arrester test area by mistake, a detector can detect an intruding person and sends a current signal to warning equipment to trigger the warning equipment to operate, and the tester or the non-tester is warned, so that the tester or thenon-tester can avoid danger in time; when the lightning arrester finishes the test operation or the lightning arrester does not start, an induced voltage device cannot induce the voltage, so that thedetector is disconnected from an external power supply or is kept disconnected from the external power supply, namely the detector is in a stop working state, and thus, the service life reduction caused by excessive work of the detector is effectively avoided. Therefore, the lightning arrester test device automatically performs early warning on personnel mistaken entry in the test process, automatically stops the operation of the detector in the non-test process, realizes intelligent protection, and greatly improves the safety in the lightning arrester test process.

Description

technical field [0001] The invention relates to the technical field of electrical testing, in particular to a lightning arrester testing device and a lightning arrester testing system. Background technique [0002] Surge arrester is one of the main equipment of the power system. It can effectively limit the overvoltage amplitude of the power grid, ensure that the substation equipment is not damaged by overvoltage, and ensure the safe and stable operation of the system. It is also called an overvoltage protector. It is suitable for overvoltage protection of transformers, transmission lines, power distribution panels, switch cabinets, power metering boxes, vacuum switches, parallel compensation capacitors, rotating electrical machines and semiconductor devices. [0003] In the electrical test of power distribution equipment, the leakage current test of the arrester is a very important item. At present, there are many types of test platforms developed for arrester current test...
