摘要
针对INFI-90系统热电阻测量回路在信号断线或信号接线松动时热电阻显示最大值,容易造成保护误动作问题提出了解决方案,对其他使用INFI-90系统的电厂有一定的借鉴意义。
In view of INFI-90 system thermal resistance measurement circuit becomes less crowded when the signal broken line or the signal wire loosing the thermal resistance demonstration maximum value, easy to create the protection to move the question to propose by mistake the solution. For other power plant which used INFI-90 system to have offer instructions to significance.
