Abstract

The invention provides a + / -800kV DC power transmission line hot-line electrical inspection device, and the device comprises a power module, a binocular visual unit, electric field induction equipment and an electrical inspection output module, wherein the power module, the binocular visual unit, the electric field induction equipment and the electrical inspection output module are respectively connected with a microprocessor. The power management module provides working power for the microprocessor. The binocular visual unit collects image information. The microprocessor recognizes a detected wire in a DC power transmission line according to the image information, and calculates the distance from the detected wire to the device. The electric field induction equipment measures the electric field surrounding the detected wire according to the distance from the detected wire to the device. The microprocessor judges whether the detected wire is electrified or not according to the electric field measurement result. The electrical inspection output module outputs the electrification information of the detected wire. The device is small in size, is light in weight, is large in range, is high in reliability, and can achieve the contact-type or non-contact type electrical inspection of the line through an unmanned plane or an insulating operation rod.

Description

technical field [0001] The invention relates to an electric inspection device, in particular to an electric inspection device for live work of a ±800kV direct current transmission line. Background technique [0002] With the construction of ultra-high voltage transmission lines, live working technology is an important technical means to ensure the reliability of the line. In order to ensure the safety of operators, the electric inspection of the line is an important technical means. UHV transmission lines and UHV substation equipment need to be checked to see if they are live when they are powered on and overhauled during a power outage to prevent accidents. According to the regulations in the "Safety Work Regulations of the Electric Industry", when working on electrical equipment that is completely or partially powered off, technical measures such as power failure, power inspection, installation of grounding wires, hanging signs and installation of barriers must be taken. ...
