Intelligent circuit breaker controller

Abstract

The invention discloses an intelligent circuit breaker controller which comprises a signals acquisition module for acquiring working voltage of all circuits of a circuit breaker, electrical signals and frequency signals, a monolithic integrated circuit control module for receiving output signals of the signals acquisition module, and a power module for supplying power for all used electricity units in a system. The input end of the monolithic integrated circuit control module is connected with a key input module, the output end of the monolithic integrated circuit control module is connected with a liquid crystal display module and an execution mode, the execution mode is connected with an anti-interference module for connecting an execution module signal line and the power module into the ground through piezoresistor, the monolithic integrated circuit control module is connected with a communication module, the signals acquisition module comprises an air-core transformer and a signal conditioning circuit which is connected with the air-core transformer, the execution mode comprises an execution origin for operating a motor reclosing module, a reset circuit and a release control unit, and the reset circuit and the release control unit are respectively connected with the execution origin. The intelligent circuit breaker controller is fast and agile, strong in monitoring, and capable of conducting the remote opening and closing.

Description

technical field [0001] The invention relates to an intelligent circuit breaker controller. Background technique [0002] As one of the important electrical appliances in the power distribution system, the low-voltage circuit breaker protects the power distribution network from damages such as short circuit, overload and ground fault.... Electricity systems have higher and higher requirements for circuit breakers, and circuit breakers are gradually developing from electromagnetic to electronic. At present, the electromagnetic type of short circuit breakers in the market generally have low intelligence, poor segmentation ability, unstable performance, high operational risk, single function, poor monitorability, and remote control, etc., and the country is vigorously developing smart grids, which requires The matching power distribution products must be intelligent and networked. Because of its faster and faster development, smart circuit breakers are more and more popular wit...
