Embodiment Construction

[0043] Below in conjunction with accompanying drawing, the present invention will be further described with specific embodiment:

[0044] The induction power-taking device used for the overhead high-voltage transmission line applied by the method proposed by the present invention, such as figure 1 In the structure shown, the alternating magnetic field generated around the high-voltage transmission line passes through the iron core to generate induced electromotive force at both ends of the induction coil, and then passes through the rectifier bridge to convert the alternating current into direct current to charge the battery; the monitoring circuit consists of sensors, signals It consists of conditioning circuit, MCU (microcontroller) and relay driving circuit. Closing and opening of the relay can stop and proceed the charging process. The monitoring circuit is used to monitor the state of the battery charging and discharging process, mainly monitoring the battery voltage, ch...

Abstract

The invention relates to the technical field of high-voltage induction power taking, in particular to a parameter matching method for an induction power-taking device for an overhead high-voltage transmission line. According to the method, a working mode of charging a storage battery by using electrical energy induced by an induction coil through a rectifying bridge is adopted, and the mode can store the induced electrical energy and provide a stable voltage source for a working circuit; and the power-taking device can take maximum energy by reasonably configuring parameters such as the sectional area of an iron core, the turn number of a secondary winding, the voltage of the battery and the like. Compared with the conventional induction power-taking device, the induction power-taking device of the invention can take more electrical energy under the conditions of the same iron core and high-voltage bus current, and has great significance for the electric equipment with high energy consumption and strict requirements for size and weight.

Description

technical field [0001] The invention relates to the technical field of high-voltage induction power acquisition, in particular to a parameter matching method of an induction power acquisition device used for overhead high-voltage transmission lines. Background technique [0002] The power extraction device for overhead high-voltage transmission lines is an energy conversion device that uses the alternating magnetic field around the high-voltage line to extract electric energy. It is mainly used for energy supplementation of high-power electrical equipment (such as line inspection robots). The high-voltage line induction power-taking device is a power conversion device used on the live line of the high-voltage line. It is composed of an iron core, an induction coil (secondary winding), a rectifier bridge, a battery and a monitoring circuit. The power converted by the power-taking device will be Stored in the battery, the battery mainly plays the role of voltage stabilization ...
