10kV centrally installed switchgear partial discharge test work execution holder, system and method

Abstract

The invention discloses a 10kV centrally installed switchgear partial discharge test work execution holder, a system and a method. The 10kV centrally installed switchgear partial discharge test work execution holder comprises a chassis, a middle part of the chassis is provided with a rotatable pedestal, a telescopic boom is arranged on the pedestal, and a tail end of the telescopic boom is provided with a holding end; a front end of the chassis is provided with a stand column, the top of the stand column is provided with a camera; the chassis is also provided with a battery pack and a controlsystem, and the control system is connected with a camera and controls movement of the pedestal, the telescopic boom and the holding end. With the holder, the system and the method provided by the invention, partial discharge test speed can be uniform and regulatable, discovery of hidden defects of equipment is facilitated, a base for safe and stable operation of a power grid is enhanced, and thelast defense line for human body safety is formed.

Description

technical field [0001] The invention relates to the technical field of partial discharge testing of central cabinets, in particular to a gripper, system and method for performing partial discharge testing of 10kV central cabinets. Background technique [0002] At present, each operation and maintenance team is generally equipped with a partial discharge tester. In practice, after many months of testing, no partial discharge case is often found. The discharge equipment and discharge location were accurately found out when the air ultrasonic partial discharge retest was carried out again. Comparing the retest pattern with the previous team test pattern, it is found that the discharge test values ​​are very different. After careful analysis, it is found that the first reason is that the detection probe itself has a magnetic attraction, and it is often easy to absorb the 10kV central cabinet door during detection, resulting in detection data. Incorrect; Second, because the dete...

Comparing the retest pattern with the previous team test pattern, it is found that the discharge test values ​​are very different. After careful analysis, it is found that the first reason is that the detection probe itself has a magnetic attraction, and it is often easy to absorb the 10kV central cabinet door during detection, resulting in detection data. Incorrect; secondly, because the detection probe is far away from the central cabinet, the discharge waveform signal collected by the probe is weak, resulting in the detection data error
