Handheld partial discharge detection device

Abstract

A handheld partial discharge detection device provided by the present invention comprises an insulating sheath and a partial discharge detector movably arranged in the insulating sheath, the insulating sheath comprises an upper shell and a lower shell, the upper shell and the lower shell are mutually buckled and connected, the front end of the insulating sheath is provided with a pressure detection device, and the pressure detection device is connected with the partial discharge detector. The insulation sheath is also provided with a power supply module for supplying power to the pressure detection device, the pressure detection device is arranged at the front end of the insulation sheath, and the power supply module is used for supplying power to the pressure detection device, so that when the partial discharge detector is used for performing partial discharge detection on the cabinet surface of the power distribution cabinet, the power supply module is used for supplying power to the pressure detection device. The pressure detection device can well detect whether the partial discharge detector is tightly attached to the cabinet surface of the power distribution cabinet or not, so that the effectiveness of the detected numerical value is ensured, multiple times of detection are not needed, one-time detection can be realized, the detection efficiency is greatly improved, the detection accuracy can be ensured, and the safety and durability of the power distribution cabinet are ensured.

Description

technical field [0001] The invention relates to the field of electric power operation detection equipment, in particular to a hand-held partial discharge detection device. Background technique [0002] With the rapid development of the national economy, the requirements for the reliability of power equipment are getting higher and higher. As the central brain of the power grid, the importance of the substation is self-evident. As we all know, there are a large number of high-voltage equipment in the substation, and the partial discharge of high-voltage equipment is persistent, concealed and unpredictable. In recent years, with the continuous increase in the number of substations and the continuous improvement of the level of intelligent operation and inspection, regular partial discharge detection of high-voltage equipment in substations is an important part of substation operation and maintenance work. [0003] Partial discharge detector is the abbreviation of high voltag...

Problems solved by technology

[0004] However, in order to ensure the accuracy of the detection, the existing partial discharge detectors on the market generally detect multiple times and take the average value to obtain an accurate detection value. However, this operation will make the operation time too long. However, it affects the operation efficiency, and the value detected at the same time is not necessarily accurate.
