specific Embodiment approach

[0027] The specific embodiment: the present invention will be further described below in conjunction with accompanying drawing:

[0028] like figure 1 Shown is a schematic diagram of the power taking principle of the present invention, the number 1 shown in the figure is the transmission line wire, 2 is the capacitance imagined between the induction electrode plate and the line wire, 3 is the high impedance value coil, 4 is the impedance transformer, 5 for the load.

[0029] The present invention provides a non-contact electric field induction method for obtaining electricity. The steps of the method are as follows:

[0030] a. Use the induction electrode plate close to the line wire, so that the induction electrode plate and the line wire form a capacitor, and use the capacitor to receive the electric energy on the transmission line;

[0031] b. Apply a transformer with high transformation ratio and high excitation impedance to transform the high voltage and small current p...

Abstract

The invention provides a non-contact electric field type induction power access method. The method is characterized in that: the method comprises the following steps that: a, an induction electrode plate is used to approach a line wire, so that a capacitor is formed by the induction electrode plate and the line wire; and the capacitor is utilized to receive electric energy on a power transmission line; and b, a high transformation ratio and high excitation impedance transformer is applied to convert a high voltage and low current power source that is transmitted by the induction electrode plate into a low voltage and heavy current power source, so that the converted power source is suitable for application to a general electric device. According to the invention, a working power source that is needed by and is suitable for monitoring equipment can be stably obtained; the effect is obvious; and the method and the apparatus are beneficial for popularization and application in the on-line monitoring field of electric network equipment.

Description

technical field [0001] The invention provides a method for obtaining power by using the principle of electric field induction near the charged conductor. Background technique [0002] With the in-depth development of smart grid and condition-based maintenance, online monitoring of grid equipment has been paid more and more attention. The extensive influence of the equipment online monitoring system plays a very important role in knowing the equipment operation status in time. As an important part of the power grid, the transmission line is also very important to monitor its operation status. Since there is often no mains power supply around the transmission line, the monitoring device cannot easily obtain the power required for work. [0003] Battery-solar panels are commonly used at present. There are also few manufacturers that use wind energy and solar energy for combined power supply, but solar energy and wind energy are too dependent on weather conditions and are inc...
