摘要
针对我国煤炭系统10 kV电网的实际情况和当前高压综合保护装置的状况,提出煤矿井下高压线路的主要故障类型及采用解决问题的基本技术途径,在此基础上选用C8051F构成一个单片机保护、测量系统,由大液晶面板显示电网的运行情况,通过触摸键盘实现参数的无级整定。充分利用了单片机的优点,它的开发应用为确保煤矿电网安全运行起到重要作用。
According to the actual conditions of the 10 kV electric power network and the present status of the high voltage comprehensive protection devices in China coal industry,the paper provided the main fault type of the high voltage lines in underground mine and the basic technical access to solve the problems.The C8051F micro processor was selected to be a micro processor protection and measurement system.The operation of the electric network can be displayed on the large LC displayer.With the touch key board,...
