DETAILED DESCRIPTION

[0017] In order to make the technical solution of the utility model more clear, the utility model is further described below in conjunction with the specific embodiments of the drawings.

[0019] Among them, the high-voltage section device 2 includes a high-voltage section gas tank 21, a composite casing 22 and a pressure equalizing hood 23. The high-voltage section gas tank 21 is vertically connected with the composite casing 22, and the end of the composite casing 22 is connected with the pressure equalizing hood 23. The electrical equipment in the composite casing 22 can play a conductive role, and the pressure equalizing hood 23 can control and reduce the pressure to protect the safety of personnel and equipment.

[0020] Among them, cable guide frames 41 are symmetrically connected on both sides of the middle joint bracket 4. The cable guide frames 41 can support, stabilize and guide the first cable 5 and the second cable 6, thereby ensuring the stability of the connection between the first cable 5 and the second cable 6.

[0021] Wherein, a set of cable guide wheel frames 41 are symmetrically connected on both sides of the middle joint bracket 4.

[0022] Among them, the length of the first cable 5 is equal to the length of the second cable 6. When the high-pressure section gas compartment 21 is connected to the first cable 5 or the tail section gas compartment 3 is connected to the second cable 6, the moving distance can be reasonably controlled to prevent the cable from being inserted too much and causing a malfunction.

[0023] Working principle: When the intermediate joint needs to be tested, the high-pressure section gas chamber 21 and the tail section gas chamber 3 are first evacuated and filled with SF6 gas to 0.4MPa, and then the intermediate joint to be tested is installed on the intermediate joint bracket 4, and GIS is installed on the first cable 5 and the second cable 6. Epoxy sleeves are provided in the high-pressure section gas chamber 21 and the tail section gas chamber 3, and high voltage is connected to the top of the composite sleeve 22. Since the high-pressure section device 2, the intermediate joint bracket 4 and the tail section gas chamber 3 are all driven by a motor, the tail section gas chamber 3 and the second cable 5 are first driven by the motor to connect. The second cable 6 is connected, and the stress cone 24 in the tail section air chamber 3 is pressed by the second automatic cone pressing frame 81, and then the second cable 6 is driven by the tail section air chamber 3 to pass through the cable guide wheel frame 41 and connect with the first cable 5. At the same time, the high-voltage section device 2 is driven by a motor to connect with the first cable 5, and the stress cone 24 in the high-voltage section air chamber 21 is pressed by the first automatic cone pressing frame 71. Then, the motor is started to drive the middle joint bracket 4 to move, so that the middle joint coincides with the position where the first cable 5 and the second cable 6 are connected, and the testing operation of the middle joint can be started;

[0024] When it is necessary to test the cable accessory GIS, first open the cone plate 25, install the GIS to be tested in the epoxy sleeves of the high-voltage section gas chamber 21 and the tail section gas chamber 3, put in the cone holder, close the cone plate 25 to fix the cone holder, and then evacuate the high-voltage section gas chamber 21 and the tail section gas chamber 3 and fill them with SF6 gas to 0.4MPa as described above, start the motor to drive the tail section gas chamber 3 to drive the second cable 6 to pass through the cable guide wheel frame 41 and connect with the first cable 5, and then drive the high-voltage section device 2 to connect with the first cable 5 through the motor, and press the stress cone 24 in the high-voltage section gas chamber 21 through the first automatic cone pressing frame 71, and then start the testing operation of the cable accessory GIS.
