[0004] To achieve the above objectives, this utility model provides an integrated device for measuring the grounding wire and insulating rod of a GIS bushing, including a U-shaped measuring head for connecting to the transmission wire at the top of the GIS bushing, the U-shaped measuring head being connected to a measuring head wire, and a base. An electric push rod is hinged to the base, and the telescopic rod of the electric push rod is fixedly connected to the U-shaped measuring head. One end of a hydraulic rod is also hinged to the base, and the other end of the hydraulic rod is hinged to the electric push rod.

[0005] Furthermore, the U-shaped measuring head includes a U-shaped frame, within which two opposing springs are hinged, and a spring is provided between the springs and the U-shaped frame. The springs are connected to the measuring head's lead wires.

[0006] Furthermore, both the base and the electric push rod are equipped with limiting rings for the measuring head wires to pass through.

[0007] Furthermore, the base is provided with a U-shaped groove, and the electric push rod is hinged in the U-shaped groove.

[0008] Furthermore, a baffle is installed above the electric actuator.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] like Figures 1 to 2 As shown in the embodiment of this utility model, an integrated device for measuring the grounding wire and insulating rod of a GIS bushing is provided. It includes a U-shaped measuring head 1 for connecting to the transmission wire at the top of the GIS bushing. The U-shaped measuring head 1 is connected to a measuring head wire 2. It also includes a base 3. An electric push rod 4 is hinged to the base 3. The telescopic rod of the electric push rod 4 is fixedly connected to the U-shaped measuring head 1. One end of a hydraulic rod 5 is also hinged to the base 3. The other end of the hydraulic rod 5 is hinged to the electric push rod 4.

[0017] The U-shaped measuring head 1 includes a U-shaped frame 101, with two opposing springs 102 hinged inside the U-shaped frame 101. A spring 103 is provided between the springs 102 and the U-shaped frame 101, and the springs 102 are connected to the measuring head wire 2.

[0018] Both the base 3 and the electric push rod 4 are equipped with limiting rings 6 for the measuring head lead wire 2 to pass through.

[0019] A shield 7 is installed above the electric push rod 4; the shield 7 serves to provide shade and protection from rain.

[0020] In some embodiments, the base 3 is provided with a U-shaped groove 301, and the electric push rod 4 is hinged in the U-shaped groove 301; the U-shaped groove 301 can support the electric push rod 4.

[0021] like Figure 3As shown, the above embodiment is applied to GIS equipment 8. The main body of GIS equipment 8 is located inside GIS room 9, and the GIS sleeve 801 at the end is located outside GIS room 9. GIS sleeve 801 is set vertically, and a transmission wire 10 is connected to the top of GIS sleeve 801.

[0022] In the above embodiment, the base 3 is fixedly connected to the outside of the GIS chamber 9. In the initial state, the telescopic rod of the electric push rod 4 and the hydraulic rod 5 are both in the retracted state. When connecting the U-shaped measuring head 1 to the transmission wire 10, firstly, the telescopic rod of the electric push rod 4 drives the U-shaped measuring head 1 to extend outward to one side of the transmission wire 10. Then, the hydraulic rod 5 extends, bringing the U-shaped measuring head 1 closer to the transmission wire 10. Finally, the telescopic rod of the electric push rod 4 drives the U-shaped measuring head 1 to retract inward, so that the transmission wire 10 is locked between the two springs 102, completing the connection between the U-shaped measuring head 1 and the transmission wire 10. After the U-shaped measuring head 1 is connected to the transmission wire 10, the end of the measuring head wire 2 away from the U-shaped measuring head can be grounded or connected to a megohmmeter, thereby realizing the remote measurement of the grounding or insulation resistance of the GIS bushing 801.

[0023] The above embodiments, by setting up electric push rods and hydraulic rods, can drive the measuring head to the wire connection at the top of the GIS bushing at a designated position, thereby realizing the grounding of the GIS bushing and the remote measurement of the insulation resistance of the GIS bushing; no manual wire connection is required, making the operation more convenient and safer.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
