Embodiment 1

[0030] Such as figure 1 As shown, a high-voltage induction plate is set in the high-voltage electromagnetic field of the high-voltage electrical equipment, and the low voltage obtained by the high-voltage induction plate is connected to a grounded capacitor to generate a microcurrent, and the grounded capacitor is used for primary energy storage.

[0031] The voltage control adopts a circuit including thyristor, impedance and trigger tube. The trigger terminal and positive pole of the thyristor are connected in series with the impedance and trigger tube. The positive pole of the thyristor is connected to the primary energy storage element, and the negative pole of the thyristor Connect the elements that use energy storage, and the trigger voltage of the trigger tube is 12V-400V. When the voltage of the primary energy storage reaches the maximum voltage, the elements of the primary energy storage discharge; when the voltage of the primary energy storage does not reach the maxim...

Embodiment 2

[0039] Such as image 3 As shown, a high-voltage induction plate is set in the high-voltage electromagnetic field of the DC high-voltage line to generate a micro-current. The weak current does not need to be rectified, but directly stores primary energy, and supplies energy storage to the application through voltage control.

[0040] The high-voltage line power transmission, thyristor conduction or cut-off, rectification and filtering involved in the present invention are all common prior art and are mastered by those skilled in the art.

Abstract

The invention discloses a non-contact high-voltage power obtaining method, which belongs to the field of monitoring or protecting equipment of high-voltage electric equipment. The method is characterized by comprising the following steps of: first, obtaining micro power by utilizing a high-voltage electric field generated around the high-voltage electric equipment; then, performing primary energy storage on the micro power; next, performing application energy storage after the primary energy storage reaches a certain voltage value by controlling a voltage; and finally, supplying power to an electrical appliance by using the application energy storage serving as a power supply. In the method, energy conservation and environment friendliness are achieved; continuous power supply to the electric appliance can be realized without influence caused by a short-circuit current or a requirement on a line current; and required power can be provided by using a no-load transmission line.

Description

technical field [0001] The invention provides a non-contact high-voltage power-taking method, which belongs to the field of power supply applied to high-voltage electrical equipment and high-voltage substation monitoring or protection equipment. Background technique [0002] At present, bird repelling devices, on-line detection or metering devices for high-voltage overhead transmission lines or transformers are mainly powered by batteries. Due to the limited power of batteries, manual live work is required to replace batteries regularly, which not only greatly reduces the usable time of the devices, but also increases Reduced the workload of live work and potential personal safety hazards. In order to prolong the usable time of these devices, it is necessary to increase the capacity of the energy source, resulting in a substantial increase in the weight of the devices, which limits the practical application of these devices. [0003] In order to solve this problem, the rese...
