摘要
中压开关柜在长期运行过程中,开关柜中触点因老化或接触电阻过大而发热,由此而引起的开关柜故障在开关设备故障中比例较高,所以对中压开关柜内的温度状态实时监测非常必要。本文采用的基于C8051F020单片机的远红外测温法,利用红外测温技术,以温度传感器为测温元件,监测中压开关柜带电工作状态下母线和电器元件连接处的发热情况,克服了中压开关柜内高温高电压的困难,实现了对中压开关柜内温度的实时采集,达到了对温升在线监测的效果。
Medium voltage switchgear in the long-running process, switchgear contacts due to aging or exposure to excessive resistance heating the switchgear fault which caused a higher proportion of switch equipment failure, so the medium-voltage switch cabinetthe temperature state real-time monitoring is very necessary. In this paper, based on the C8051F020 MCU far infrared thermometry, to overcome the difficulties of the high-temperature and high-voltage switch cabinet,to achieve real-time acquisition of medium voltage switchgear cabinet temperature to achieve the effect of the temperature rise of online monitoring.
