摘要
为提高煤矿电力系统的抗干扰能力,设计采用了终端加电阻附加交流电源的监视保护装置。分析了终端加电阻附加交流电源的绝缘监视保护原理,并从硬件、软件及抗干扰方面介绍了高压防爆开关微机保护装置绝缘监视保护模块的设计。试验表明,该保护模块具有抗干扰性强、动作可靠的特点。
In order to improve the anti disturbance ability of the coal mine power system, the monitoring and protection device of the terminal and the electric power supply is adopted. This paper analyzes the principle of the insulation monitoring and protection of the terminal and the additional AC power source, and introduces the design of the insulation monitoring and protection module of the high voltage explosion-proof switch microcomputer protection device from hardware, software and anti-interference. Experiments show that the protection module has the characteristics of strong anti-interference and reliable operation.
