[0030] Furthermore, the fixing rod 400 includes a bent rod 401 and a straight rod 402. There are at least two sets of bent rods 401, and each end of the straight rod 402 is connected to a bent rod 401. One end of the bent rod 401 is connected to the bottom of the auxiliary support rod 103, and the other end passes through the cover plate on the side of the tank 200 where the moving side electrode 202 is located. The top of the auxiliary support rod 103 is fixedly connected to the bent rod 401.

Several casters 104 are installed at the bottom of the base frame 102 for easy movement; preferably, casters 104 with self-locking function can be used.

[0032] In this embodiment, as Figure 4 As shown. The insulating basin 201 divides the tank 200 into two chambers, which can be filled with test gases for testing; for example, when testing the electrode, the chamber containing the electrode can be filled with environmentally friendly gas, while the other chamber remains filled with SF6. The opposite is true when testing the sleeve 300.

[0033] Example 2

[0034] Reference Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, when testing the electrodes, environmentally friendly gas is filled into the gas chamber containing the electrodes on one side of the insulating basin 201, and SF6 is filled into the gas chamber containing the conductor on the other side of the insulating basin 201, and then the test is carried out.

[0036] Furthermore, when testing the bushing 300, environmentally friendly gas is filled into the gas chamber containing the conductor on one side of the insulating basin 201, and SF6 is filled into the gas chamber containing the electrode on the other side of the insulating basin 201, and then the test is carried out.

[0037] Preferably, when replacing the electrode, the connection between the tank 200 and the insulating basin 201 is disconnected, and the connection between the tank 200 and the support frame 100 is disconnected, so that the tank 200 can slide along the curved rod of the fixed rod 400; the electrode is replaced or the interior is cleaned when there is sufficient clearance between the tank 200 and the insulating basin 201.

[0038] Preferably, when disassembling the tank 200 to replace the electrode, a slider with a pulley can be placed on the bent rod to support the tank 200 so that the fasteners, bolts, and screws on the tank 200 can be loosened. The slider and pulley roll on the bent rod, making it easier to move the tank.

[0040] It should be noted that the auxiliary rod 105 can be fixed to the base frame by means of hinges, etc., and the opening angle can be freely controlled to prevent the equipment from tipping over during assembly and testing; the shelf 101 can be used to place environmentally friendly gas cylinders and test equipment.

[0041] It should also be noted that when replacing the contacts, loosen the connection between the electrode housing 200 and the insulating basin 201, as well as the connection between the housing 200 and the support frame 100. Remove the housing 200 and place it on the bent rod of the fixing rod 400, allowing the housing 200 to slide on the bent rod towards the handwheel 204a. Once there is sufficient clearance between the housing 200 and the insulating basin 201, the moving and stationary electrodes can be replaced or the interior can be cleaned. The fixing rod 400 passes through the through hole in the cover plate to guide and prevent the housing from accidentally falling. This utility model has a small overall footprint, with a width of less than 1 meter. When the auxiliary rod 105 is closed, it has strong mobility, and when the auxiliary rod 105 is open, it can prevent tipping. When replacing the electrodes, the fixing rod 400 provides support, saving time and effort.
