Abstract

The invention provides a double-coil inner and outer ring type induction energy taking system, which comprises an energy taking coil, a switch module, an anti-impact module, a rectification filtering module, an overvoltage protection module, a voltage reduction and stabilization module and an energy storage module, and is characterized in that the switch module comprises a first switch, a second switch, a third switch and a current relay; the voltage reduction and stabilization module comprises a front-end DC / DC step-down transformer and a rear-end DC / DC voltage stabilizer, the input ends of the first switch and the second switch are connected with an ultracrystalline magnetic core energy-taking coil and a silicon steel magnetic core energy-taking coil in the energy-taking coil respectively, and the output ends of the first switch and the second switch are connected with the rectification filtering module through the anti-impact module. The output end of the rectification filtering module is connected with an overvoltage protection module for controlling the first switch and the second switch and a front-end DC / DC step-down transformer, and the output end of the front-end DC / DC step-down transformer is connected with a rear-end DC / DC voltage stabilizer through a current relay, an energy storage module and a third switch. The double-coil and inner and outer ring mode is adopted to take energy, the energy taking dead zone is reduced, and the energy taking current range, the energy taking efficiency and the output power are increased.

Description

Technical field [0001] The present invention relates to the field of transmission of transmission lines, and more particularly to a double coil inner and outer ring type sensing unit. Background technique [0002] The operating state of the electrical equipment and the transmission line is critical to the stability and reliable operation of the power system. Online monitoring technology can monitor each running parameters in real time, and real and effective reflection of the actual situation of equipment insulation, and is an important technical means to ensure the safety of equipment and line operations. However, in some applications, the online monitoring device has a problem that the power supply is not easy to acquire, the existing power supply plan reliability is poor, so the power supply is one of the important factors that restrict the development of online monitoring technology. Currently used solutions include photovoltaic power supply, capacitive voltage power supply, ...
