High voltage capacitor-based energy taking power supply arranged in ZW20 switch

Abstract

The invention discloses a high voltage capacitor-based energy taking power supply arranged in a ZW20 switch, which comprises a shell, a high-voltage input terminal, a first output plug and a second output plug, wherein one end of the high-voltage input terminal is fixedly installed on one side of the shell through a thread, the first output plug and the second output plug are fixedly connected tothe inner wall of the shell through snap spring type terminals, one end of the first output plug and one end of the second output plug both penetrate through the shell and extend out of the shell, anda high-voltage energy taking capacitor and a low-voltage energy taking capacitor are fixedly installed on the inner wall of the shell through arc-shaped fixing rings from top to bottom. The inventionrelates to the technical field of electrical equipment. According to the high voltage capacitor-based energy taking power supply arranged in the ZW20 switch, the 10kV plateau type energy taking capacitor is simple in structure, compact in installation, stable and reliable in performance, good in use effect, capable of being installed easily, conveniently and rapidly, long in service life and capable of effectively solving the power supply problem of 10kV overhead power distribution lines.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an energy harvesting power supply based on a high-voltage capacitor built in a ZW20 switch. Background technique [0002] In the construction of distribution network automation system, the problem of power acquisition of automation devices has always been a major bottleneck in the upgrading and transformation of distribution network lines. Some use electromagnetic voltage transformers to obtain power, some use current transformers to obtain power, and some The use of solar power generation devices to obtain electricity requires either large investment in implementation and application, or complex and unreliable wiring, and may be affected by external factors such as operating environment, climate change, and line load, which limits the development of distribution network automation. [0003] The power supply of equipment in the online monitoring of transmission lines...
