[0025] The tank body 1, the insulator 2, the conductor 3, the fixed components 4, the wiring cylinder 8 and the lightning protection mechanism 9 are provided. Through the wiring cylinder 8, the corresponding cylinder of the GIS can be docked, so that the external wires can pass through the fixing plate 81 and respectively penetrate through the communication holes 810 to transition into the tank body 1, effectively ensuring the miniaturization of the overall GIS. Secondly, the installation and disassembly of the insulator 2 can be facilitated by operating the explosion-proof sheet 5.

[0026] As Figure 2 shown in the figure, the utility model provides a technical solution for a pot-type lightning arrester for GIS: The lightning protection mechanism 9 includes a rubber pad 91. The top of the rubber pad 91 is fixedly connected with a fixing seat 92. The top of the fixing seat 92 is fixedly connected with an insulating rod 93.

The top of the core body 96 abuts against the bottom of the insulator 2. Inside the tank body 1, the lightning protection mechanism 9 effectively ensures the lightning protection performance of the device.

[0027] As Figure 3 shown in the figure, the utility model provides a technical solution for a pot-type lightning arrester for GIS: A connection groove 101 that penetrates through the inside and outside is opened on one side of the tank body 1 close to the wiring cylinder 8. A fixing plate 81 is fixedly connected to the inner wall of the wiring cylinder 8. A plurality of communication holes 810 that penetrate through the front and rear are opened in a circular array inside the fixing plate 81. Through the communication holes 810 provided in the fixing plate 81, the wires can be transitioned into the tank body 1 for connection.

[0028] As Figure 4 shown in the figure, the utility model provides a technical solution for a pot-type lightning arrester for GIS: A fixing sleeve 20 is fixedly connected to the bottom of the insulator 2. Connecting plates 21 are respectively fixedly connected to the left and right sides of the outer wall of the fixing sleeve 20. Positioning grooves 210 are opened at the far ends of the two connecting plates 21 away from each other. Fixing grooves 211 are opened at the tops of the two connecting plates 21. The inner wall of the fixing sleeve 20 is sleeved on the outer wall of the tank body 1. The insulator 2 can be installed on the top of the tank body 1 through the fixing sleeve 20.

[0029] As Figure 5As shown in the figure, the utility model provides a technical solution for a pot-type lightning arrester for GIS: The fixing component 4 includes a fixing plate 41. One end of the fixing plate 41 away from the tank body 1 is provided with a movable groove 410. An L-shaped plate 42 is arranged inside the movable groove 410. A plug rod 43 is inserted vertically into the L-shaped plate 42, and the front and rear ends of the plug rod 43 penetrate through the outer wall of the fixing plate 41 and are movably connected therebetween. A T-shaped pull rod 44 is arranged on the transverse surface of the L-shaped plate 42, and the T-shaped pull rod 44 penetrates through the upper and lower ends of the transverse surface of the L-shaped plate 42. A groove 420 is opened on the lower surface of the transverse surface of the L-shaped plate 42. A spring 45 is sleeved on the outer wall of the T-shaped pull rod 44 away from the groove 420. One end of the T-shaped pull rod 44 away from the fixed block 46 is fixedly connected with a fixed block 46 having the same size as the fixed groove 211 and the groove 420. A positioning plate 47 having the same shape and size as the positioning groove 210 is fixedly connected to the side of the L-shaped plate 42 close to the fixed block 46 in the vertical direction. The bottom of the spring 45 is fixedly connected to the transverse surface of the L-shaped plate 42, and the top of the spring 45 is fixedly connected to the lower surface of the top of the L-shaped plate 42.

The L-shaped plates 42 on both sides are turned upwards respectively, and the T-shaped pull rod 44 is pulled upwards, so that the spring 45 is stretched upwards, so that the fixed block 46 is retracted into the groove 420. The L-shaped plate 42 is stuck at the outer end of the connecting plate 21, so that the positioning plate 47 is inserted into the positioning groove 210. Then, the pulling force on the T-shaped pull rod 44 is released, and the elastic force of the spring 45 is used to reset the fixed block 46 and snap it into the fixed groove 211, so as to install the insulator 2 on the top of the tank body 1, which is convenient for replacing the insulator 2. Since the wiring cylinder 8 is communicated with the tank body 1, the wiring cylinder 8 is a docking end for docking with the corresponding cylinder of the GIS. A fixing disk 81 is arranged inside the wiring cylinder 8. By arranging the lightning protection mechanism 9 inside the tank body 1, through the resistance sheet 94 arranged outside the insulating rod 93 and the core body 96 arranged on the inner contact seat 95, it effectively meets the supporting construction of the GIS. The external wire can pass through the fixing disk 81 and penetrate the communication hole 810 respectively to transition to the tank body 1, effectively ensuring the overall miniaturization of the GIS.
