When the GIS shell is particularly long (up to about 10m), the above-mentioned method can only be used to inspect and clean it within the limited space of the GIS shell. If metal particles are generated in the middle of the GIS shell and are not cleaned in time, it will cause great harm to the operation of the GIS. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0025] When GIS is overhauled, the busbar temperature changes violently and frequently under the dual influence of daily temperature changes and current-carrying heat. The GIS shell and conductor materials are made of aluminum alloy, and the conductor and the contact seat are connected by sliding. Temperature changes cause deformation, and the conductors produce metal particles due to thread friction between the contact seats or shaking during transportation. The metal particles are removed using the following devices:

[0026] Example 1

[0027] like Figure 1-5 As shown, a tooling vehicle for a GIS busbar cavity is provided. The tooling vehicle 2 is located in the cavity 3 of the GIS shell 1 and is used to automatically clean metal particles in the cavity 3 of the GIS shell 1 before the GIS is energized. The tooling vehicle comprises a vehicle body 21 and wheels 22 installed at the bottom edge of the vehicle body 21 and driven by a motor. Lights 23 are respectively installed on the top and bottom of the vehicle body 21. An electromagnet 26 facing downward for adsorbing metal particles in the cavity 3 is also installed at the exact center of the bottom of the vehicle body 21.

[0028] A control panel 25 is also installed on the vehicle body 21 . The output ends of the control panel 25 are electrically connected to the two lighting lamps 23 , respectively. The electromagnet 26 and the motor for controlling the driving of the wheel 22 are both electrically connected to the output ends of the control panel 25 .

[0029] An inlet 4 and an outlet 5 are respectively provided at both ends of the side wall of the GIS housing 1 . The above solution is adopted in order to install the tooling vehicle 2 in the GIS housing 1 from the inlet 4 and then exit from the outlet 5 .

[0030] The control panel 25 is also provided with a WIFI communication module, which is connected to an external terminal for communication. By adopting the above solution, instructions are transmitted to the control panel in real time through a mobile phone, and the control panel controls the relevant equipment to perform operations respectively.

[0031] It should be noted that the electromagnet 26 can be connected to an external power source by an external wire, or a battery box can be provided on the vehicle body and the electromagnet can be powered by a battery provided inside the battery box.

[0032] Working principle: Put the tooling vehicle 2 into the inlet 4 of the GIS housing 1, first use the control panel 25 to start the two lighting lamps 23, the electromagnet 26 and the motor respectively, so that the tooling vehicle 2 can move under the condition of light. During the movement, there are mainly the following working modes:

[0033] As the tooling vehicle 2 moves in the cavity 3 of the GIS housing 1 , the electromagnet 26 is used to absorb the metal particles in the cavity 3 of the GIS housing 1 while the tooling vehicle 2 moves.

[0034] As another embodiment, Figure 6 As shown, this embodiment is basically the same as Embodiment 1, except that a tooling vehicle is used for the GIS busbar cavity, the tooling vehicle 2 is located in the cavity 3 of the GIS shell 1, and cameras 24 are respectively provided on the top and bottom of the vehicle body 21 to check the installation status of the GIS busbar inside the cavity 3 of the GIS shell 1.

[0035] Working principle: Put the tooling vehicle 2 into the inlet 4 of the GIS housing 1, first use the control panel 25 to start the two cameras 27, the lighting lamp 23 and the motor respectively, so that the tooling vehicle moves under the condition of light, that is, the motor drives the wheels 22 to rotate and walk in the cavity 3. During the movement, there are mainly the following working modes:

[0036] As the tooling vehicle moves in the cavity 3 of the GIS shell 1, two cameras 24 are used to shoot in the cavity 3 of the GIS shell 1, and the cameras 24 have a 360-degree rotation function (it should be noted here that there are many cameras 24 with a rotation function on the market, and how they rotate is not elaborated here), and the captured content is transmitted to the control panel 25, and the control panel 25 transmits it to the computer through the WIFI communication module, and finally the captured photos or videos are displayed on the computer, so as to check the installation status of the bottom of the busbar in real time.

[0037] The tooling vehicle 2 in the utility model is placed in the cavity 3 of the GIS shell 1. The tooling vehicle 2 can move in the cavity 3 of the GIS shell 1, so it is not limited by the length of the cavity 3 of the GIS shell 1, and can clean the entire cavity 3 of the GIS shell 1. Compared with the previous manual digging mode, the working method is improved, that is, the electromagnet 26 is used to absorb the metal particles in the cavity 3 of the GIS shell 1. In addition, the installation status of the GIS busbar in the cavity 3 of the GIS shell 1 can be checked through the setting of two cameras 24 and a control panel 25, which ultimately improves the efficiency of cleaning and inspection. (It should be noted that the number of lighting lamps 23 turned on is set according to the needs of actual maintenance or cleaning operations), which ultimately improves the efficiency of cleaning and inspection.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
