摘　　要：金属铠装移开式开关柜由于内部结构原因,以往采用的红外测温仪或红外热成像仪无法安全、有效地测量到断路器室动、静触头的温度,会因动、静触头接触不良过热导致大量的电气事故。在线测温装置能实时监测动、静触头的接触温度,上传到温度接收终端及变电所综合自动化监控后台,为无人值守变电所的安全运行提供了有力的技术支持。Due to the internal structure of metal armored movable switchgear,the previous infrared thermometer or infrared thermal imager can not safely and effectively measure the temperature of moving and static contacts in the circuit breaker room,which will lead to a lot of electrical accidents due to poor contact and overheating of moving and static contacts.The online temperature measuring device can monitor the contact temperature of moving and static contacts in real time and upload it to the temperature receiving terminal and the integrated automatic monitoring backstage of the substation,which provides strong technical support for the safe operation of unattended substation.
