| 摘 要： | 为了避免单一方法在开关柜局部放电检测和定位时所存在的局限性,提出一种暂态地电压、超声波和超高频联合检测方法,通过在带电运行的35 kV开关柜上进行实际应用分析,表明联合检测法能有效对开关柜局部放电缺陷进行检测和定位,对开关柜的日常局放检测工作具有借鉴意义。

| Abstract: | In order to avoid the limitation of the single detection and location method of partial discharge in switchgear,an united detection method is presented by combining transient earth voltage,ultrasonic and ultra-high-frequency method.With the practical application in operating 35 kV switchgear,it shows that the united detection method can detect and locate the partial discharge effectively in switchgear,which plays a certain guiding significance for field applications. |
