电力电缆表面温度的监测

Monitoring System for Surface Temperatures of Power Cables

本文通过对电力电缆热特性研究，得出了电力电缆表面温度与各参量的关系。在此基础上提出了一种主从分布式多机电力电缆表面温度监测系统方案。该系统结构灵活、操作方便、实时性强，是实现电力电缆表面温度监测，预防火灾发生的一种较好方案。对该系统稍加修改，也可以构成其它物理量的监测系统。

The relationship between surface temperatures of power cables and various other parameters is obtained by studying heat characteriedcs of power cables. On this basis, a master-slave distributed multi-computer surface temperature monitoring system for power ables is suggested.The system has features of active structure, simple operation, strongly real-time, and can be utilized to ensure safe operation of power cables. With slight modifcation, it is easy to convert into a system for monitoring other physical quantities.
