变电站温湿度控制器断线报警分析

Disconnection Alarm of Temperature and Humidity Controller in Transformer Substations

变电站温湿度控制器断线报警可能导致温控器退出运行,使温控器的实际投入率降低。以济南电网为例,深入分析温湿度控制器断线报警的原因,充分考虑济南地区气候特点,对其设计原理和整定值的优化提出改进措施,解决温湿度控制器投入率较低的问题,使二次机构能够有效地避免温度和湿度的影响,确保变电设备的安全稳定运行。

Disconnection alarm of temperature and humidity controller may lead to the quit of temperature controller, lower the actual investment rate of the controller. Taking Jinan power grid as an example, causes of the temperature and humidity controller disconnection alarm are analyzed, and optimization measures of design principle and setting value are proposed considering characteristics of Jinan power grid. The low input rate of temperature and humidity controller is increased, and the second mechanism can effectively avoid the influence of temperature and humidity, which assure the safe and stable operation of electric equipment.
