摘要
介绍一种基于DSP +CPLD的矿用隔爆型高压真空开关数字式综合保护系统的组成结构和实现方法 ,对电参量测量原理 ,继电保护分合闸控制电路的CPLD反馈控制原理 ,以及过流反时限数字保护现实原理作了详细叙述 。
The paper introduced the structure and operation method of the digital comprehensive protection system for mine flame proof high voltage vacuum switch base on DSP+CPLD. The paper has a detail introduction on the electric quantity measuring principle, the CPLD feedback control principle of the relay protection tripping and closing control circuit and the implemental principle of the over current reversing time limit digital protection. The paper has a technology development outlook of the digital comprehensive protection system for the flame proof high voltage switch.
