Embodiment 1

[0026] Embodiment 1: as attached figure 2 As shown, the high-voltage cable is suspended and installed on the high-voltage line tower through the insulator, and the angle steel is fixed on the high-voltage line tower as the supporting structure of the device of the present invention. It is fixed on the angle steel by installing hoops and a few-shaped brackets.

[0027] In the embodiment of the present invention, the sun-blind semiconductor single-tube ultraviolet detector adopted by the ultraviolet sensor can track and detect the corona discharge of the equipment at a fixed point, orientation, long distance (2m-50m), and real-time in the ultraviolet band, and the working wavelength is image 3 shown. When the power transmission equipment discharges, it will radiate ultraviolet light, that is, electromagnetic waves in the ultraviolet band. By analyzing the spectrum of the ultraviolet light, it is found that there is a section of the spectrum that avoids the ultraviolet band of ...

Abstract

According to an ultraviolet online remote real-time monitoring device for abnormal discharge of the power transmission and transformation equipment, an ultraviolet sensor is connected to an AD circuit, the AD circuit is connected to an MCU unit and a wireless transmission module at the same time, and the MCU unit is connected to the wireless transmission module. In addition, the photovoltaic powersupply is connected to the ultraviolet sensor, the AD circuit, the wireless transmission module, the MCU unit and the photovoltaic power supply respectively. A photocurrent signal of an ultraviolet sensor is subjected to digital integration operation, detection data is subjected to integration sampling and AD conversion, and the sampling data is transmitted to a background system through a wireless module according to a sampling frequency and a sampling threshold set by an MCU unit and is sent to a background for real-time detection through multiple wireless transmission protocols. Through alow-integration low-power-consumption design, early warning of a fault is intelligently realized, remote real-time monitoring of abnormal discharge of power equipment is realized, and safe operation of on-grid equipment is guaranteed. The automation degree is high, the response speed is high, the detection efficiency is high, manual field operation is not needed, and the operation cost of power equipment is greatly reduced.

Description

technical field [0001] The invention belongs to an IPC classification G01R31 / 00 electrical performance testing device or an electrical fault detection device, relates to the technical field of abnormal discharge detection of electric power equipment, and particularly relates to an ultraviolet online monitoring device for abnormal discharge of outdoor power transmission and transformation equipment. Background technique [0002] With the continuous growth of transmission lines, the traditional manual line inspection method has become less and less suitable for the requirements of transmission line safety and power supply reliability. Under the action of long-term electrical, thermal, mechanical and environmental factors, power transmission and transformation equipment will have reduced insulation performance and structural defects, resulting in phenomena such as corona discharge and surface partial discharge. The detection of corona discharge on electrical equipment is helpfu...
