Abstract

The invention relates to the field of intelligent permanent magnetic high pressure vacuum circuit breakers, in particular to an intelligent modularized permanent magnetic mechanism controller. The intelligent modularized permanent magnetic mechanism controller comprises a microcontroller, and is characterized in that the microcontroller is respectively connected with a contact temperature sampling circuit, a switch current voltage acquisition circuit, a switch position state circuit, a capacitor voltage sampling circuit and a remote local control circuit so as to obtain input information; and the microcontroller is also respectively connected with an IGBT (Insulated Gate Bipolar Translator) drive module, a direct current motor drive circuit, a relay state indicator lamp circuit, an LCM (liquid crystal module) and a voice integrated module so as to output the information and an instruction. The invention provides the intelligent modularized permanent magnetic mechanism controller, which has the functions of monitoring the mechanical properties and the contact temperature of a high pressure vacuum circuit breaker on line, achieving the voice guide operation and controlling an electric pushing mechanism in addition to the function of the conventional permanent magnetic controller, and can effectively prevent the potential hazard of the operation accidents of the vacuum circuit breaker and avoid the misoperation accidents.

Description

technical field [0001] The invention relates to the field of intelligent permanent magnet high-voltage vacuum circuit breakers, in particular to an intelligent modular permanent magnet mechanism controller. Background technique [0002] As a core component of the permanent magnet high voltage vacuum circuit breaker, the permanent magnet mechanism controller is widely used by many high voltage vacuum circuit breaker manufacturers. The traditional permanent magnet mechanism controller is mainly to meet the control requirements of the momentary high current of the permanent magnet mechanism opening and closing, and to realize undervoltage lockout, fault alarm, and communication functions, and does not have the mechanical characteristics of high-voltage vacuum circuit breakers. , Contact temperature online monitoring and voice-guided operation, electric propulsion mechanism control, circuit breaker anti-jumping and other functions, but with the demand for intelligent constructio...
