DETAILED DESCRIPTION

[0022] The technical scheme in the embodiment of the utility model is clearly and completely described below. Figure 1 The technical scheme in the embodiment of the utility model is clearly and completely described below.

[0023] Embodiment one

[0024] Reference Figure 1 , Figure 2 A withstand voltage test tool for GIS equipment, comprising a shell 15, an insulation torsion bar 6, an output shaft 7, a rotating shaft 5, an electric conductor 16, an electric rod 17, a rotating plate 1 and a dynamic side contact seat 3.

[0025] Wherein, the insulation torsion bar 6 is fixed on the outer surface of a single side edge of the shell 15, and the output shaft 7 is arranged in the interior of the shell 15; one end of the output shaft 7 is fixedly connected with the insulation torsion bar 6 through the shell 15, and the other end of the output shaft 7 is nestedly connected with one end of the rotating plate 1 through the rotating shaft 5.

[0026] In operation, the output shaft 7 is used for external connection of a motor and the like driving facility, and the motor drives the rotation of the output shaft 7, so that the rotating shaft 5 rotates along with the output shaft 7, and finally drives the rotating plate 1 to rotate.

[0027] Meanwhile, the other end of the rotating plate 1 is fixedly connected with the moving side contact seat 3, and the moving side contact finger 4 is arranged on the side of the moving side contact seat 3 away from the rotating plate 1, and the rotating shaft 5 and the moving side contact seat 3 are respectively located on the two sides of the rotating plate.

[0028] Through the above arrangement, the rotating plate 1 drives the moving side contact seat 3 to rotate in the process of rotating; and the moving side contact seat 3 performs withstand voltage test on the three-phase conductor by means of the moving side contact finger 4 arranged thereon.

[0029] In the existing withstand voltage test tool, the output shaft 7 usually plays the functions of driving the rotating plate 1 to rotate and conducting electricity; and with the use of the withstand voltage test tool, the output shaft 7 will be worn to a certain extent, or loose with other structures such as the rotating shaft 5, etc., so that the output shaft 7 and other structures are in poor contact, thereby reducing the insulation performance of the output shaft 7 itself; at this time, if the withstand voltage test on the three-phase conductor is performed through the conduction of the output shaft 7, it will not be able to accurately judge whether the three-phase conductor has insulation performance.

[0030] In order to solve this problem, the embodiment nests the conductor 16 at the connection between the output shaft 7 and the rotating shaft 5, and makes the conductor 16 adhere to the rotating plate 1, and also fixedly connects one end of the conducting rod 17 with the conductor 16; the other end of the conducting rod 17 extends out of the shell 15 and is used for external testing equipment, so as to realize the withstand voltage test on the three-phase conductor.

[0031] By rotating the handle connected to the output shaft 7, the insulating torsion rod 6, the rotating shaft 5, the rotating plate 1 are sequentially driven to rotate, and then the moving side contact seat 3 is driven to rotate to a specified position, and the moving side contact finger 4 is in contact with the conductor 10.

[0032] With reference to Figure 1 , the withstand voltage test tool further comprises a three-phase insulator 11, a conductor 10, a density relay 8 and a porcelain sleeve 9.

[0033] Specifically, the three-phase insulator 11 is fixedly installed in the shell 15, and a through hole is formed in the three-phase insulator 11; one end of the conductor 10 is nested in the through hole, and the other end of the conductor 10 is used for contacting the moving side contact finger 4. Meanwhile, the through hole formed in the three-phase insulator 11 is also used for connecting the conductor in the GIS device, which in this embodiment is the A-phase conductor 12, the B-phase conductor 13 and the C-phase conductor 14.

[0034] In order to improve the safety performance of the whole withstand voltage test tool, and effectively fix and support the shell 15, the porcelain sleeve 9 is nested with the shell 15; and the other end of the conductive rod 17 extends out of the shell 15 and is located inside the porcelain sleeve 9, which can isolate high-voltage and low-voltage wires through the porcelain sleeve 9, prevent current from directly passing through, and ensure the safe operation of the test.

[0035] The density relay 8 is arranged outside the shell 15 and fixedly connected with the outer surface of the shell 15, and is used for monitoring the gas density in the shell 15. Through the density relay 8, it can be monitored in real time whether SF6 gas leakage occurs during the withstand voltage test of the GIS device, so as to ensure the safe operation of the whole withstand voltage test.

[0036] Based on the above description, the use steps of the withstand voltage test tool are as follows:

[0037] Step one: first fix one end of the three-phase conductor (A-phase conductor 12, B-phase conductor 13 and C-phase conductor 14) in the through hole on the three-phase insulator 11, and contact with the conductor 10; at the same time, the output shaft 7 is connected with the motor device, and the conductive rod 17 is connected with the test device.

[0038] Step two: drive the output shaft 7 to rotate through the motor, and drive the moving side contact seat 3 to the specified position through the sequentially connected rotating shaft 5 and rotating plate 1, and contact with the conductor 10 through the moving side contact finger 4.

[0039] Step three: at this time, the test device is connected with the A-phase conductor 12 through the conductive rod 17, the conductive body 16, the rotating plate 1, the moving side contact seat 3 and the conductor 10 in sequence, so as to conduct the withstand voltage test of the connected A-phase conductor 12.

[0040] Step four: after completing the withstand voltage test of the A-phase conductor 12, repeat steps two and three to conduct the withstand voltage test of the B-phase conductor 13 and the C-phase conductor 14.

[0041] Step five: after completing the withstand voltage test of the A-phase conductor 12, B-phase conductor 13 and C-phase conductor 14, turn off the connected test device, and use the motor to return the moving side contact seat to the original position.

[0042] Through the above setting, the output shaft 7 only plays the function of rotation; and the conductive body 16 and the conductive rod 17 only play the function of conduction, so as to realize the complete separation of conduction and rotation, thereby avoiding the problem that the output shaft 7 cannot conduct the withstand voltage test of the three-phase conductor due to wear or poor contact when it plays the functions of rotation and conduction at the same time.

[0043] The utility model discloses above although the specific embodiment of the utility model has been described in conjunction with the drawing, is not the limit to the protection scope of the utility model, and the person skilled in the art should understand that on the basis of the technical scheme of the utility model, various modifications or deformation that the person skilled in the art can make without paying creative labour are still within the protection scope of the utility model.
