Intelligent self-energy-obtaining vacuum breaker

Abstract

The invention discloses an intelligent self-energy-obtaining vacuum breaker. The intelligent self-energy-obtaining vacuum breaker comprises a base, a three-phase vacuum extinction chamber device, three high-voltage current mutual inductors and a spring energy storage operation mechanism, wherein the base is installed with a valve switching-on / off operation rod and an energy storage operation rod which are connected with the spring energy storage operation mechanism. The intelligent self-energy-obtaining vacuum breaker further comprises an intelligent controller for controlling the vacuum breaker; an energy obtaining device for obtaining electric power from a high-voltage operated circuit and supplying the electric power to each power utilization unit is mounted at the top end of the base; a signal processing unit for processing signals output by the energy obtaining device and signals output by the high-voltage current mutual inductors is mounted on the base; the energy obtaining device is electrically connected with the upper end of the vacuum extinction chamber device; the energy obtaining device and the high-voltage current mutual inductors are connected with the signal processing unit; and the signal processing unit is connected with the intelligent controller. The intelligent self-energy-obtaining vacuum breaker provided by the invention has the advantages of compact structure, novel and reasonable design, high reliability, good security property, strong practical applicability, and high popularization and application values. The intelligent self-energy-obtaining vacuum breaker is good for prompting the development of an automatic distribution network.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and in particular relates to a self-energy intelligent vacuum circuit breaker. 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 high-voltage voltage transformers to obtain power, some use high-voltage current transformers to obtain power, and some There are many disadvantages in utilizing solar power generation devices to obtain electricity. In the implementation and application, either the investment is large, or the wiring is complex and unreliable, and it may be affected by external factors such as environmental location, weather and load, which limits the development of distribution network automation.
