随着供电负荷的迅速增加及高压电力设备的老化,厂站因设备过热而引起的火灾、爆炸事故时有发生,且危害性极大,带电设备的连接点处更为易发点,如断路器、隔离开关触头等。据国家电力安全事故通报统计,我国每年仅发生在电站的电力事故,40%是由高压电器设备过热所致。因此,对高压带电设备温度在线监测是保证厂站安全运行的重要内容。
With the rapid increase of the power supply load and the aging of high-voltage power equipment, fire and explosion accidents caused by overheating of the plant station occur frequently and are extremely harmful. The connection point of the charged equipment is more prone to the point of disconnection Disconnector contacts, etc. According to the national electric power safety accident notification statistics, our country only takes place in power plant accidents every year, 40% is caused by overheating of high-voltage electrical equipment. Therefore, on-line monitoring of high-voltage live equipment temperature is to ensure the safe operation of the plant an important part.
