| 摘 要： | 在很多情况下,电抗器直接接在GIS母线上,在GIS中开关操作时会产生VFTO,VFTO以行波的方式通过母线传播到套管,并耦合到GIS外部端子、电抗器及与之相连的设备,对其带来危害。以某330kVGIS为例,利用EMTP计算了GIS中投切电抗器时VFTO的幅值、波形,并分析了各种因素对电抗器端部过电压的影响,以及避雷器对该过电压的抑制作用。

| Abstract: | In many cases, reactors are directly connected to the GIS bus, the circuit breaker operation may generate VFTO, which would propagate towards the bushing along the bus in the form of travelling wave, and be coupled to the outside terminals. The reactor as well as the other equipment connected with the reactor may be subjected to the dangerous stress. This paper computes the waveforms and the maximal amplitudes of such case, and analyses the influence factors. The suppression effect of MOA is also discussed. |
