description The utility model provides a 500kV switch expansion joint fixing device. The 500kV switch expansion joint fixing device comprises a steel sheet, a round steel rod, a nut and a thread, one end of the steel sheet is vertically fixed at one end of the round steel rod; the upper end of the thread is located on a main body of the round steel rod and is in threaded connection with a nut. When the fixing device provided by the utility model is used for replacing a sleeve for maintenance and replacement of a 500kV main transformer, a GIS flange screw rod is fastened by using the screw hole on the steel sheet, and then the screw tooth end extends into the screw hole of the expansion joint and is fastened by using the screw cap, so that the expansion joint of the main transformer can be supported, and the risk existing in manual support is avoided. 本实用新型提供一种500kV开关伸缩节固定装置，包括钢片、圆钢杆、螺帽和螺牙；钢片的一端垂直固定于圆钢杆的一端，另一端设有螺孔；圆钢杆的另一端固定连接有螺牙，螺牙上端位于圆钢杆的主体上螺纹连接有螺帽。本实用新型的固定装置用于500kV主变维修换更换套管时，利用钢片上的螺孔禁锢GIS法兰螺杆，然后将螺牙端伸入伸缩节的螺孔中并用螺帽禁锢，即可对主变
