|
摘要
针对高压开关柜接地开关因机械故障、人为误操作、机柜设备过热等原因导致的设备故障、工作人员触电等问题,设计一种新型的智能控制接地开关操控装置。以STM32F103为核心处理器搭建硬件平台,并根据模块化的设计理念确定总体设计方案及各功能模块的电路图;通过C语言完成软件模块各单元中主要功能的程序流程图。实验结果表明,操控装置的电动控制可靠性高,可以准确地执行软启动、软停止、全速运行、急停等操作,及时地响应堵转等故障灵敏动作。实现了电动操控接地开关的分闸、合闸操作。
Aiming at the problems of equipment failure and staff electric shock caused by mechanical failure,artificial misoperation and overheating of cabinet equipment,a new type of intelligent control grounding switch control device is designed. The hardware platform is built with STM32F103 as the core processor,and the overall design scheme and the circuit diagrams of each functional module are determined according to the modular design concept. The program flow chart of the main functions of each unit of the software module is completed by C language. The experimental results show that the electric control reliability of the control device is high,and it can accurately perform soft start,soft stop,full speed operation,emergency stop and other operations,and timely respond to fault-sensitive actions such as shutdown. The operation of opening and closing ground switch with electric control is realized.
