Abstract

The invention relates to a self energy taking power supply device. A self energy taking capacitor adopts a capacitor voltage dividing form, the stability is high, and the cost is low; and meanwhile no transformer is connected to two ends of a low-voltage capacitor, the volume and weight of a power supply and an intelligent switch are greatly reduced, and the electromagnetic interference and visual pollution due to overhead line distribution network layout are reduced. The self energy taking power supply device takes power from a wire inlet side of a high-voltage switch, is unaffected by a line load, and can also provide a switch operating power supply when power supply and distribution lines fail.

Description

technical field

[0001] The invention relates to a self-energy-taking power supply device, which is used in the field of intelligent switches. Background technique

[0002] At present, there are mainly the following types of intelligent switch energy harvesting technology: 1. Voltage transformer type, which can be used to supply power to the automatic monitoring device of overhead line distribution network, but due to its vulnerability to external environment, system impact, pouring quality and other aspects Influenced by various factors, many voltage transformer explosion accidents occurred during operation, which seriously affected the safe operation of distribution lines. 2. The current transformer type, which uses the primary side to induce the high-voltage bus current to obtain the secondary side electric power output. When the bus current changes from several amperes to several thousand amperes, the working power obtained by this method is extremely unstable. When the ...
