Problems solved by technology

Due to the wide frequency range and high amplitude of inductive discharge, strong interference will be generated in the surrounding environment, and the device for measuring current has no electromagnetic protection, so the error of the measurement result is very large, and it even cannot work normally.
[0004] At present, there is no test device for 0-GHz broadband and strong current. Therefore, it is urgent to combine the special electromagnetic environment of the operation of the power distribution robot, and equip the induction discharge current test device that is resistant to strong electromagnetic interference, and propose a method for testing the induction discharge current of the power distribution robot.

Abstract

The invention provides an induced discharge current testing method and device for a power distribution live-line work robot. The induced discharge current testing device comprises current measuring equipment, a discharge electrode and a current sensor. The current measuring equipment comprises a shielding box, an oscilloscope and a device for providing power for the operation of the oscilloscope are arranged in the shielding box, the side wall of the shielding box is provided with joints which are in butt joint with the outside, namely an optical fiber joint and a shielded wire joint, and theoscilloscope is connected with an upper computer through the optical fiber joint; and after the discharge electrode is connected with the current sensor through a discharge current measuring cable, the discharge current measuring cable penetrates through the shielded wire joint to be connected with the input end of the oscilloscope. The current measuring equipment, the discharge electrode and thecurrent sensor are reasonably matched and connected, so that the robot induced discharge current in the space radiation field can be tested in time.

Description

technical field [0001] The invention belongs to the field of electromagnetic compatibility of high-voltage power transmission and substation engineering, and in particular relates to a method and device for testing the induced discharge current of a power distribution live working robot. Background technique [0002] It is an inevitable direction of technological development that live working robots replace workers in live working in distribution networks. In order to meet the requirements of live work on distribution lines, a high-voltage live work robot that meets the requirements of the on-site working environment to the greatest extent is currently being developed. The robot is exposed to harsh electromagnetic environments, and EMC testing and evaluation are urgently needed. [0003] When the power distribution robot is working with electricity, various ports are exposed to the complex electromagnetic generated by the high-voltage line, and the robot may malfunction or r...
