变电站开关柜温度监测系统设计

The Design of the On-line Monitoring System for Temperature of Transformer Substation Switchgear

文章首先讨论了变电站设备中常用的几种温度监测方法,阐明了光纤测温传感器应用于电力系统设备上的优势。应用荧光光纤测温传感器作为测温节点,完成变电站内开关柜设备的温度监控系统设计,介绍了荧光光纤测温原理及系统施工,并对聊城110kV开发区站开关柜进行温度监控,验证了系统的稳定性。

In this paper the several methods of transformer substation devices＂ temperature momtormg are uscussed. The advantages of using fluorescence fiber temperature measurement method in switchgear monitoring are introduced. The paper designs the switchgear on -line monitoring system based on fluorescence fiber temperature sensors. It explains the system principle and construction of the monitoring system. The system was applied in the Liaocheng 1 lOkV Kaifaqu transformer substation, and the stability has been validated.
