基于多通道光纤加速度测试分析法测温的研究与分析

Research and Analysis of Temperature Measurement Based on Multi Channel Fiber Acceleration Test Analysis Method

摘要: 发电厂、变电站的高压开关柜、母线接头、室外刀闸开关等重要的设备，因长期运行，造成设备老化或接触电阻过大发热，由于这些发热部位的温度无法监测，最终导致事故发生。近年来，在电厂和变电站已发生多起开关过热事故，造成火灾和大面积的停电事故，解决开关过热问题是杜绝此类事故发生的关键，实现温度在线监测是保证高压设备安全运行的重要手段。

Abstract: Because of the long-term operation, high voltage switch cabinet, bus connector, outdoor knife gate switch and other important equipments of power plant and substation become the aging equip-ments and contact resistance has the high fever, due to the temperature of the heating parts cannot be monitored, eventually accidents happen. In recent years, many accidents about switch overheating have occurred in power plant and substation, resulting in fire and power outage in large area. So solving overheating problems of the switch is the key to preventing such accidents, and realizing online temperature monitoring is an important way to ensure safe operation of high voltage equipment.
