Research for Methodologies Solving Temperature Protection Miss Actuation Caused by Thermal Resistors
Based on the analysis for history data of temperature measured by RTD,which field wirings is loosed,put forward three methods for preventing the protect logic against being acted faultily:Temperature changing Rate value judgment,Temperature changing Rate Direction judgment,and Technical Comparison judgments.And statistical the variety of temperature changing rate in any case of wirings loosed by Matlab software.Those logic judgment methods are used in practice,which effectively prevent equipment from tripping accident caused by wiring loosening.
