              Energy monitoring system for wireless temperature measurement of iDTS2020W switchgear

              Energy monitoring system for wireless temperature measurement of iDTS2020W switchgear

              The system can be applied to all kinds of indoor high-voltage switchgear head head, contact and busbar on-line temperature monitoring, can effectively prevent the occurrence of overheating failure. The temperature measurement unit of the system adopts the direct contact method to carry on the accurate temperature measurement to the monitoring point, the temperature measurement unit transmits the monitored temperature change to the receiving device on the low pressure side through the wireless communication way, and carries on the multi- Kind of alarm tips. Wireless temperature measurement unit fully considered in the high voltage, high current, high temperature and other complex conditions of work reliability, through multiple reliable technology to ensure the safety of the temperature unit. The temperature measuring unit is made of high temperature and insulating material, and has no bare metal parts. It can be installed in parts such as busbar, static contact, moving contact, cable joint and so on. Switch cabinet structure, but will not reduce the thermal stability of the switchgear, temperature performance, insulation safety distance, insulation and other insulation performance and other safety performance.
