摘要
针对现有容型设备在线监测系统对主变压器设备介损的测量结果不准确,抗干扰性能、抗温度和湿度变化能力差等问题,探讨容性设备介损在线监测系统的关键技术,为判断电力设备的绝缘状况提供可靠依据。介绍了信号采样电路、介损测试电路和分析方法的设计,通过在线监测系统对主变设备的介损进行了实测,并对比传统试验数据,证明了该技术的有效性。
Aiming at the problems such as inaccuracy,poor anti-interference performance and poor ability to resist temperature and humidity changes of measurement results of dielectric loss of main transformer equipment by on-line monitoring system of existing capacitive equipment,the key technology of an on-line monitoring system for capacitive casing loss was discussed to provide reliable basis for judging insulation status of power equipment.The signal sampling circuit,dielectric loss test circuit and analysis method were introduced.The dielectric loss of the main variable casing was measured through the on-line monitoring system,and the effectiveness of the technique was proved by the comparison of the traditional test data.
