摘　　要：具有“五防”功能的环网柜在电缆运行状态下处于常闭状态,普通红外测温仪器无法通过玻璃观察窗进行测温。为此,设计了一套基于单片机技术的10 kV环网柜电缆终端温度在线监测装置。将装置的温度传感器部分固定在电缆终端上,可直接测量电缆终端运行温度,实现实时监测。该装置经初步应用,取得了良好效果。The ring network cabinets with "five-prevention" function are normally in closure state when the cables are live,and the ordinary infrared temperature measurement instruments cannot measure the temperature through the glass observation window.In view of this problem,a gadget for online monitoring of 10 kV ring network cabinet cable terminal temperature was designed utilizing the single chip machine technology.By fixing the temperature sensors of the gadget onto the cable terminal,the measurement of operating temperature of ring network cabinet cable terminal was achieved,which also allowed real-time temperature monitoring.The device displayed satisfactory utility in preliminary preliminary practical application.
