Abstract: Temperature is an important parameter that characterizes the normal operation of electric primary equipment. With the rapid increase in power consumption, in order to meet the demand for electricity, high and low voltage equipment such as switch cabinets in substations are operating online for a long time. Overload operation will cause heating and overheating of primary equipment. This phenomenon is especially true in areas with fast load growth. universal. If these situations are not monitored and dealt with in time, unpredictable accidents will occur. Through real-time monitoring of the temperature of the switchgear, the operating conditions of the switchgear can be known, and the integration of power grid information resources can provide a strong basis for condition maintenance. Therefore, safe temperature monitoring and intelligent control are very necessary.
