Transmission line iced conductor galloping aerodynamic parameter monitoring device and monitoring method

Abstract

The invention discloses a transmission line iced conductor galloping aerodynamic parameter monitoring device comprising an integrated online transmission line monitoring unit and an online conductor galloping monitoring unit which is arranged on an iced conductor. The integrated online transmission line monitoring unit is connected with the online conductor galloping monitoring unit through 3G signals, and is connected with a monitoring center background system through a 3G network. The invention further discloses a method for monitoring the aerodynamic parameters of iced conductor galloping by using the transmission line iced conductor galloping aerodynamic parameter monitoring device. By adopting the transmission line iced conductor galloping aerodynamic parameter monitoring device and the monitoring method of the invention, the icing thickness of an iced conductor of a transmission line and the real-time aerodynamic parameters during galloping of the iced conductor can be acquired accurately.

Description

technical field [0001] The invention belongs to the technical field of state monitoring devices for power transmission and transformation equipment, and in particular relates to an aerodynamic parameter monitoring device for galloping ice-coated conductors of power transmission lines. The method of aerodynamic parameters. Background technique [0002] In winter, some areas in my country are affected by the macroclimate, micro-topography, and micro-meteorological conditions. The galloping accidents of transmission line ice-coated conductors occur frequently, and the galloping of transmission line ice-coated conductors will cause a sharp decline in the mechanical and electrical performance of the transmission line, which is likely to cause phase-to-phase flashover. The network, fittings and insulators are damaged, the wires are broken, the bolts of the tower are loose and fall off, the tower materials are damaged, the foundation is damaged, and even a series of serious accident...

[0002] In winter, some areas in my country are affected by the macroclimate, micro-topography, and micro-meteorological conditions. The galloping accidents of transmission line ice-coated conductors occur frequently, and the galloping of transmission line ice-coated conductors will cause a sharp decline in the mechanical and electrical performance of the transmission line, which is likely to cause phase-to-phase flashover. The network, hardware and insulators are damaged, the wires are broken, the bolts of the tower are loose and fall off, the tower materials are damaged, the foundation is damaged, and even a series of serious accidents such as the collapse of the tower will be caused, resulting in huge economic losses.
