Abstract

The invention discloses a power supply device of an online monitoring device for power transmission lines. The power supply device comprises an energy converting module, a power supply converting module, a magnetorheological fluid vibration attenuation module, a noise reduction module and an antitheft bolt module. The energy converting module is used for converting hydraulic energy into alternating voltage power supply. The power supply converting module is used for simultaneously converting the alternating voltage power supply into a power supply for the online monitoring device for power transmission lines and a direct current power supply for a vibration attenuation system. The magnetorheological fluid vibration attenuation module is used for lowering vibration of the energy converting module. The noise reduction module is used for reducing noises of the energy converting module. The antitheft bolt module is used for preventing the whole device from being stolen. By the power supply device having brand new ideas, power supply reliability of the online monitoring device for power transmission lines is improved greatly, vibration and noise pollution are lowered, and development of online monitoring technology for power transmission lines is promoted.

Description

technical field [0001] The invention relates to the technical field of power transmission line state monitoring, in particular to a power supply device for on-line monitoring equipment of power transmission lines. Background technique [0002] Power grids at home and abroad are affected by the macro-climate, micro-topography, and micro-meteorological conditions, and accidents such as lightning damage, ice damage, bird damage, and floods occur from time to time. It caused different degrees of mechanical damage to wires, iron towers, insulators, and fittings. In severe cases, wires were disconnected and towers fell, causing large-scale power outages. Therefore, in order to effectively control the operation status of transmission lines and take effective measures in a timely manner, the technology of online monitoring and status assessment of transmission lines has been greatly developed. However, the power supply is one of the key issues when conducting on-line monitoring of ...
