In this paper

the theoretical and case analysis on the special magnetic valve structure and its partial overheating of MCR core is analyzed through the practical application of the magnetic valve controlled reactor（MCR） in the regional grid of Zhejiang Power Company

and the existence of the partial overheating of the MCR magnetic valve and its effect is pointed. On this basis

operation and maintenance work as well as standard specification for the MCR is sorted further

the existed problem and shortcoming is summarized and concluded. Finally

the need for detecting magnetic valve temperature status information for the MCR and suggestion on the development of application of on-line temperature measurement technology for the internal magnetic core magnetic valve of MCR are proposed so to enhance effectiveness of evaluation technology of MCR equipment status further

improve operation and maintenance level and operation reliability of MCR equipment.
