Technical Field

[0001] The utility model belongs to the technical field of gas cabinet switch testing, in particular to an insulation testing device for a gas cabinet switch. Background Art

[0002] A gas-filled cabinet is a switch cabinet that seals the main electrical components in a box and fills the sealed box with gas at a certain pressure as an insulating medium. When testing the performance of the switch cabinet, because the main components are sealed in the box, the input of external detection current and voltage can only be connected to the main circuit of the switch cabinet by installing a specific test device. Before testing the switch device, each component must be sealed to improve the insulation of the gas-filled cabinet switch.

[0003] In the existing method of inspecting parts, each part is subjected to a sealing inspection. However, during the inspection, due to the different sizes and shapes of different parts, the parts may move when placed, which makes the inspection inconvenient.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0020] Reference Figure 1-Figure 2, an inflatable cabinet switch insulation test device, including a base plate 1, a test box 3 is fixedly connected to the middle of the top surface of the base plate 1, support columns 2 are fixedly connected to the four corners of the base plate 1, and support legs are fixedly connected to the bottom of the base plate 1. A placement plate 8 is slidably provided in the test box 3, and the placement plate 8 is embedded in the test box 3. A plurality of pin holes 9 are opened along the top surface of the placement plate 8. The plurality of pin holes 9 surround the outer edge of the top surface of the placement plate 8. A pin rod 10 is detachably installed in each pin hole 9. The pin rod 10 is installed or removed according to the size and shape of the part to adapt to different part sizes;

[0021] A sieve plate 11 for placing parts is installed on the placement plate 8. The sieve plate 11 is located in the middle of the pin holes 9 around it. The top surfaces of multiple support rods are fixedly connected to the top plate 4. A cylinder 5 is installed through the top plate 4. The movable end of the cylinder 5 is fixedly connected to the sealing box 6 covering the detection box 3. The sealing box 6 is provided with an annular groove 12 on the side facing the detection box 3.

[0022] A reset component for resetting the placement plate 8 is provided between the placement plate 8 and the bottom wall of the detection box 3. A negative pressure machine 7 communicated with the detection box 3 is provided below the bottom plate 1. The air in the detection box 3 is evacuated by the negative pressure machine 7, and the sieve plate 11 on which the parts are placed fully drains the air in the detection box 3. The pin rod 10 is first installed in the pin hole 9, and then the parts to be inspected are placed on the sieve plate 11. The pin rod 10 is additionally installed according to the shape and size of the parts, so that the parts are placed stably, which facilitates the inspection of the parts, and by buckling the sealing box 6 on the detection box 3, the sealing performance during inspection is improved.

[0023] Reference Figure 2 The reset assembly includes a telescopic rod 14 fixedly connected between the placement plate 8 and the inner bottom wall of the detection box 3. The telescopic rod 14 is covered with a spring 15 fixedly connected between the placement plate 8 and the detection box 3. When the cylinder 5 descends, the inner wall of the sealing box 6 presses the pin rod 10 on the top surface of the placement plate 8 and descends synchronously. Then, the placement plate 8 descends, compressing the telescopic rod 14 and the spring 15 to descend. After the inspection is completed, as the sealing box 6 rises, the spring 15 will push the placement plate 8 upward to reset the placement plate 8.

[0024] Reference Figure 3 The top surface of the placement plate 8 is provided with a mounting groove 17 , and the sieve plate 11 is installed in the placement groove. The sieve plate 11 is embedded in the mounting groove 17 to facilitate the installation of the sieve plate 11 .

[0025] Reference Figure 3 A through groove 16 communicating with the detection box 3 is opened through the installation groove 17. After the sieve plate 11 is installed, due to the through groove 16 and the sieve plate 11 opened on the placement plate 8, when the placement plate 8 is pressed into the detection box 3, it is convenient to use the negative pressure machine 7 to drain the air in the detection box 3.

[0026] Reference Figure 2 A sealing gasket 13 is installed on the top wall of the annular groove 12 of the sealing box 6, and the sealing gasket 13 improves the sealing performance of the sealing box 6 and the detection box 3.

[0027] Reference Figure 2 The inward side wall thickness of the annular groove 12 of the sealing box 6 is less than the diameter length of the pin rod 10. When the sealing box 6 is pressed against the pin rod 10 of the placement plate 8, it does not interfere with the parts attached to the pin rod 10, which reduces the sealing performance of the sealing box 6 and the detection box 3.

[0028] Working principle:

[0029] First install the pin rod 10 in the pin hole 9, then place the parts to be inspected on the sieve plate 11, and install additional pin rods 10 according to the shape and size of the parts. Then, as the cylinder 5 descends, the inner wall of the sealing box 6 presses the pin rod 10 on the top surface of the placement plate 8 and descends synchronously. Then, as the placement plate 8 descends, the compression telescopic rod 14 and the spring 15 descend, and the parts on the placement plate 8 are inspected. After the inspection is completed, as the sealing box 6 rises, the spring 15 will push the placement plate 8 upward to reset the placement plate 8.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
