T型GIS模型中局部放电光学信号传播特性仿真
|
摘要
为了研究T型气体绝缘开关设备(GIS)腔体中局部放电光学信号传播特性,通过建模仿真,在不同放电位置、探测距离以及探测角度条件下,观察并分析了各个探测面上的光学信号。结果表明:1)不同放电位置情况下,GIS部件的遮挡使探测面的光斑产生暗区,减弱了探测面和探测点的光学信号强度;2)经过T型转角后,探测面位置距离放电源越远,光学信号越弱,以放电源位于x轴正方向50 cm(即x50)为例,距离放电源75 cm的平均相对辐照度是50cm时的44.31%;3)探测角度不同时,放电源直射出来的相对辐照度值较大,而被部件遮挡或者直射光较弱的探测点的值较小。以T型转角上的C1探测面,x50为放电源为例,当探测角度为270°时相对辐照度值最大,225°时最小,仅为前者的39.02%。
In order to study the propagation characteristics of partial discharge optical signals in T-type GIS cavities, the optical signals on each detection plane are observed and analyzed under the conditions of different discharge positions,detection distances and angles by modeling and simulation. The results show that: 1) In the case of different discharge positions, the occlusion of the GIS component enables the light spot on the detection plane to generate a dark area, reducing the optical signal strength of the detection plane and the detection point. 2) After T-shaped cornering, the farther the power source is away from, the weaker the optical signal will be. The x50, namely, the discharge source is set at x=50 cm, is taken as an example,it is revealed that the average relative irradiance decreases to 44.31% when the distance from the discharge source is 75 cm is compared to when the distance is 50 cm. 3) When the detection angle is different, the relative irradiance value of the detection point of direct ray is relatively large, and the value of the detection point which is obscured by the component is relatively small. The C1 detection surface and x50 coordinates on the T-type angle are taken as examples,it is revealed that the relative irradiance is largest when the detection angle is 270 degrees, and the relative irradiance is smallest when the detection angle is 225 degrees, which is only 39.02% of the former.
