GIS (gas insulated switchgear) operating position inspecting device

The invention relates to a GIS (gas insulated switchgear) operating position inspecting device, comprising a signal generating device and a display device that are independent; the signal generating device comprises an insulating transmitting shell, a transverse cylindrical transmitting light-guide barrel is disposed in the center of the insulating transmitting shell, and a light transmitter is disposed in the center of the transmitting light-guide barrel; the display device comprises an insulating display shell, a transverse cylindrical receiving light-guide barrel is disposed in the center of the insulating display shell, an a light-permeable cover is arranged on the right end surface of the insulating display shell. The GIS operating position inspecting device has the advantages that operation and maintenance staff judges opening and closing of a disconnector according to signal displaying during operation of the GIS disconnector, the problem that an actual position of the disconnector that is operated is
