The invention discloses an indicating device for contact between a moving contact and a fixed contact of a GIS voltage transformer. According to the device, an electromagnetic induction device is arranged on an ejector rod of the moving contact, and an indicator light is controlled to be turned on or off through the electromagnetic induction device. The indicating device has the advantages that the position of the moving contact is directly displayed, so that whether the moving contact and the fixed contact are in contact or not is judged, and the defect that indication is not accurate in theprior art is avoided. 本发明公开一种GIS电压互感器动静触头接触指示装置，通过在动触头的顶杆上设置电磁感应装置，并通过所述电磁感应装置来控制指示灯的开闭。本发明的优点是：直接显示了动触头的位置，从而判断动静触头是否接触，避免了现有技术指示不准的缺点。
