高压开关柜无线测温系统的研究

The Research of Wireless Temperature Measurement System for the High-voltage Switchgear

作为保证系统安全运行的重要设备的高压开关柜,其内部导电连接处过热会导致电气设备的损坏,更严重时可能会发生火灾等严重事故,因此需要对高压开关柜进行温度的监测。根据高压开关柜测温区别于普通测温系统的特点,研制了采用供能CT进行供电、无线传输方式、点对多点无线组网的无线测温系统,并对整个系统在软硬件方面采取了相应的抗干扰的措施,保证系统的可靠性。

High-voltage switchgear, as the guarantee for the safety operation of the power system, whose internal conductive joint overheating could cause the damage of the electrical equipment, and more serious. It will cause fire accidents and so on. Therefore, it needs to monitor the temperature of the high-voltage switchgear. According to the differences between the high-voltage switchgear temperature measurement system and ordinary temperature measurement system, it develops a wireless temperature measurement system which is composed of power supply CT, wireless transmission, point-to-multipoint network, and takes some anti-interference measures in software and hardware to ensure the reliability of the system.
