Zinc oxide arrester charged tester easy to use at night

Abstract

The invention discloses a zinc oxide arrester charged tester easy to use at night and belongs to the field of testers. According to the zinc oxide arrester charged tester easy to use at night, a wirelimiting column and an LED illumination lamp which can rotate automatically are arranged at the left side and the right side of a jaw of a wireless current clamp body; through cooperation of a servo motor and a driving mechanism, reverse rotation of the wire limiting column and an illumination plate provided with the LED illumination lamp is realized, so that the upper end of the jaw is in an openstate, and it is easy to arrange a wire sheath in the jaw in a sleeved mode; the LED illumination lamp which is turned over is located in the vertical direction of the side of the jaw, so that it iseasy for a technician to observe the position of a wire and perform construction operation; after the wire is embedded into the jaw, the LED illumination lamp can the wire limiting column return, thewire limiting column is buckled onto the jaw, a test is performed through the wireless current clamp, and then the LED illumination lamp is located over the wireless current clamp body. Therefore, thewhole operation environment is relatively bright, and it is easy to perform construction operation at night.

Description

technical field [0001] The invention relates to the field of testing instruments, in particular to a live testing instrument for zinc oxide arresters which is easy to use at night. Background technique [0002] DYYHX-F Zinc Oxide Surge Arrester Live Tester is a special instrument for testing the electrical performance of zinc oxide surge arresters. This instrument is suitable for live or power failure detection of zinc oxide surge arresters of various voltage levels, so as to timely detect the dampness of the internal insulation of the equipment and the valve plate. Hazardous defects such as aging. [0003] At present, the live tester of zinc oxide arrester is used for wireless testing by the host of the tester and the wireless current clamp. The wireless current clamp is fixedly installed on the insulating rod. The arrester grounding down conductor is bonded for wireless testing. In the test process, the wires are generally installed at a higher place, and the operation i...

AI Technical Summary

Problems solved by technology

In the test process, the wires are generally installed at a higher place, and the operation itself is inconvenient when clamping the wires, and the operation is difficult. Especially for night or dark operating environments, the wireless current The distance between the clamp and the ground is high. In the case of poor light, it is difficult for technicians to observe the position of the wire and it is difficult to successfully and conveniently set the wire in the jaw, which brings certain operational difficulties to the construction. Need to use external lighting equipment, the operation is more troublesome
