伴随能源发展方式转变,电力位居中心地位。智能变电所是未来电力发展的重要方向。智能变电所中控制电能的主要电力设备的安全运行影响着整个电力系统的稳定性和可靠性。常规电力设备如隔离开关、动静触头、电缆头连接部位的接触面,无论压接多紧,总有缝隙。在长期运行中,接触面氧化,接触电阻增加,进一步导致触头发热。这种触头发热又会加速接触面氧化,如不及时发现处理将会造成电力设备的损坏。因此电力设备触头实时温
With the change of energy development mode, power is at the center. Smart substation is the future direction of power development. The safe operation of the main power equipment that controls the electric energy in the smart substation affects the stability and reliability of the entire power system. Conventional power equipment such as disconnectors, moving contacts, cable head connecting parts of the contact surface, no matter how tight pressure, there are always gaps. In the long run, the contact surface oxidation, contact resistance increases, further lead to contact fever. This hot contact will accelerate the contact surface oxidation, if not promptly found that the treatment will cause damage to electrical equipment. Therefore, real-time power equipment contact temperature
