【摘要】 为提高煤矿井下供电系统的可靠性、安全性和连续性,设计了一种基于高性能处理器STM32F103的煤矿防爆高压馈电开关的智能保护系统。该系统集测量、控制、保护、通讯功能于一体,人机界面好、数据采集量大、运算速度快、能完成各种复杂保护的控制任务。4个采区变电所的改造工程证明,该系统能够用于井下供电系统的升级与改造。更多还原

【Abstract】 An intelligent protection system for coal mine explosion-proof high-voltage feed switch was designed which is based on STM32 F103. The system integrates measurement,control,protection and communication functions,with good man-machine interface,large data acquisition,fast calculation speed,and can complete various complex protection control tasks. The transformation project of the four mining substations proved that the system can be used for the upgrading and transformation of the underground power supply system.更多还原
