变电站母线接头放电发热故障监测装置研究

Research on Discharge Heating Fault Monitoring Device of Substation Busbar Joint

变电站母线接头受密闭性不足、电压流转较强等因素影响,更容易受到潮气、灰尘等的侵入,导致连接处放电发热,从而造成短路故障。针对这一问题,从光纤光栅和红外测温技术出发,提出变电站母线接头放电发热故障监测装置。通过监测装置的应用,能够实时明确母线接头温度变化趋势,从而强化故障监测效果。

Influenced by factors such as insufficient airtightness and strong voltage flow,the busbar joints in substation are more vulnerable to the invasion of moisture and dust,which leads to the discharge and heating at the joints,thus causing short-circuit faults.Aiming at this problem,based on fiber grating and infrared temperature measurement technology,a monitoring device for discharge and heating fault of substation bus joint is proposed.Through the application of the monitoring device,the temperature change trend of bus joint can be clearly defined in real time,thus strengthening the fault monitoring effect.
