Problems solved by technology

The disadvantage of this device is that the magnetic core is a ring structure, so it can only be applied to the energy harvesting environment where the current source is an ordinary cylindrical wire
However, in the switchgear of the substation, flat wires are widely used, but the above-mentioned energy harvesting device cannot use this type of wire as a current source for energy harvesting due to the mismatch in shape

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] see figure 2 , figure 2 It is a schematic diagram of the magnetic field energy acquisition device of the present invention. As shown in the figure, a substation magnetic field energy acquisition device includes: a multi-turn copper coil 1 for inducing voltage and outputting electric energy and a C-shaped first-section magnetic core 2. The coils are wound on the first section of the magnetic core in the same direction, and the distance between each two turns of the coils is small, so that the two turns of the coils are completely close to each other, and the coil taps are retained. It also includes a C-shaped second magnetic core 3, the coils are wound on the second magnetic core in the same direction, and the distance between each two turns of the coils is small, so that the two turns of the coils are completely close together. The first-segment ma...

Abstract

A transformer-substation magnetic field energy taking apparatus comprises a multi-turn copper coil used for sensing a voltage and outputting electric energy, a C-shaped first-segment magnetic core and a C-shaped second-segment magnetic core. The first-segment magnetic core is oppositely arranged to the second-segment magnetic core, and an air gap is arranged between the first-segment magnetic core and the second-segment magnetic core. The apparatus can be installed on a flat lead so as to provide electric energy for an electric appliance. Through selection of different installation modes, a greater degree of flexibility is provided for installation and maintenance of the energy taking apparatus.

Description

technical field [0001] The invention belongs to a magnetic field energy obtaining device, which is used to obtain energy from a magnetic field formed after a wire is energized, and specifically relates to a magnetic field energy obtaining device of a substation. Background technique [0002] At present, the existing magnetic field energy acquisition device adopts a circular magnetic core [1]. The overall device includes: a ring-shaped magnetic core 11 and a coil 12 . When the energy-fetching device is working, the high-voltage wire passes through the center of the ring magnetic core, and the alternating current in the wire generates an alternating magnetic field, so that the coil induces voltage and outputs electrical energy for the electrical appliance (such as figure 1 shown). The disadvantage of this device is that the magnetic core is a ring structure, so it can only be used in an energy-taking environment where the current source is an ordinary cylindrical wire. Howe...
