发电厂辅机单点轴承温度保护热控组态优化

Optimization Scheme of the Thermal Control Configuration of Bearing Single Point Temperature Protection for Auxiliary Equipment

通过对某发电厂重要辅机的单点轴承温度保护热控组态进行分析,并针对其优缺点,提出两套优化方案,以减小保护的误动和拒动的可能性。

Through analyzed the thermal control configuration of bearing single point temperature protection of important auxiliary equipment of power plant,and according to its advantages and disadvantages,put forward two sets of optimization schemes and reduced the possibility ofmal-operation and miss trip,as well as to avoid such a situation when bearing need lubrication without protection.
