Problems solved by technology

For example, the collected power frequency leakage signal is converted into frequency transmission, etc., but because the power frequency leakage is a single characteristic quantity, it cannot reflect the state of the insulator, or it is uneconomical due to the influence of network transmission; or it is dangerous, expensive, and inaccurate. , poor anti-interference ability
In addition, to inspect insulators regularly or after pollution flashover occurs, the work tasks are heavy and intensive

Abstract

The invention provides a device for detecting pollution flashover of an insulator on a transmission line in real time. The device comprises a detection part and a reception part, wherein in the detection part, the insulator is a part of an insulator string, a part of a detection module is located around the insulator, the other part of the detection module is fixed to a grounded tower, and the detection module transmits obtained signals to a detection processing module through a data line; a reception part module of the reception part comprises a wireless reception module, a second processing module, a waveform display module and a computer. The device for detecting pollution flashover of the insulator on the transmission line in real time can remotely detect the insulator on the transmission line in real time, so that pollution flashover warning information is convenient to obtain in advance for replacing or maintaining the insulator; moreover, the device is low in dangerousness, economical and reasonable in manufacturing cost, accurate in measurement and high in interference resistance and improves safety and reliability of a power grid.

Description

technical field [0001] The invention relates to a device for detecting pollution flashover of an insulator on a transmission line in real time, and more specifically, to a device for detecting pollution flashover of an insulator on a transmission line in real time. Background technique [0002] The insulator on the high-voltage transmission line not only plays the role of electrical insulation, but also plays the role of mechanical support. To ensure that the transmission line can also operate normally when overvoltage occurs, the working state of the insulator plays a crucial role in the safety and reliability of the power network. important role. Insulators will inevitably be polluted outdoors. Although in a dry climate, these polluted dust have no effect on the reliability of the insulator due to its large resistance; but in an environment with high humidity, the dust on the surface of the insulator is wet, causing the surface of the insulator to A full blown flashover o...
