Problems solved by technology

However, the technical threshold for monitoring surface leakage current is relatively high, and the cost is also relatively high, and it is also relatively susceptible to environmental influences
In addition, this system does not have mobility, and the flexibility of use has been limited
[0005]In summary, although the power system safety monitoring system has been researched to a certain extent, there is no report in the literature that wirelessly monitors the electric field near the insulator to judge the quality of the insulator, and can Device for automatic inspection of insulators along the line

Abstract

The invention discloses an insulator quality monitoring device. The device comprises an insulator suspension mechanism, an electric field sensor, a wireless transmission module, a device moving module, a wire, and a control center monitoring module. The device can monitor the quality of fixed insulators wirelessly and transmits monitoring information to the control center monitoring module by means of the wireless transmission module. If there is a deviation over 2% compared to recorded data in a system, an insulator is considered to be invalid, and the device prompts that manual maintenance is needed. Besides, the device can automatically inspect insulators in the whole line range according to needs, which cannot be accomplished by insulator quality monitoring devices in the prior art.

Description

[0001] technical field [0002] The invention relates to an insulator quality monitoring device, in particular to a device capable of realizing power system insulator quality monitoring. Background technique [0003] In recent years, more and more attention has been paid to the safety of power systems, especially the quality of insulators. However, manual monitoring is inefficient and less safe, so a low-cost device that can monitor the quality of insulators wirelessly is needed. [0004] Chinese application number CN201110086978.0, application publication number CN102221641A, which discloses an on-line monitoring system for leakage current of high-voltage transmission line insulators. Although the system can timely and accurately monitor the surface leakage current of high-voltage transmission line insulators, it can reflect the pollution status of insulator surfaces during operation in real time, and transmit on-site measured data and early warning / alarm information to th...
