The invention provides an online energy taking device for a power transmission line, and belongs to the field of power systems. The online energy taking device comprises a lightning-protection decoupling device connected to the power transmission line, the input end of the lightning-protection decoupling device is connected with an iron tower and a ground wire via joints, and the output end of the lightning-protection decoupling device is connected with the input end of a transformer; and the output end of the transformer is connected with a rectification filter via a lightning protection circuit, the output end of the rectification filter is connected with a DC-DC module, and the output end of the DC-DC module is connected with monitoring equipment via an electrolytic capacitor. A scheme that a ground wire takes energy is used in the online monitoring system. The online energy taking device has the advantages that an induction voltage, which is originally defined as power transmission loss, of a lightning conductor is re-utilized, the maintenance cost of the system is reduced greatly, the working stability of the online monitoring type equipment is improved, the service life of the same is prolonged greatly, and the device is convenient to install, simple in wiring and can satisfy requirement of reliable power supply of different types of online monitoring systems.
Description
Technical field [0001] The invention belongs to the field of power systems, and particularly relates to an online energy acquisition device for power transmission lines. Background technique [0002] The transmission line online detection system is a system that monitors the transmission line’s remote video, micro-weather, tower tilt, anti-theft alarm, icing and other line conditions through wireless public network communication and uploads it to the monitoring center. The main station is the system master. It is composed of various monitoring devices. [0003] At present, almost all the power supply modes adopted by the online monitoring devices of transmission lines are "photovoltaic panels + storage batteries". This energy supply method effectively solves the power problem of the online monitoring system for transmission lines in remote areas, but the acquisition of light energy is greatly affected by the environment. In the weather with insufficient light such as rain, snow, a...
