Abstract

This invention relates to the field of simulation verification device technology, and discloses an environmentally friendly insulating gas simulation verification device, including a housing with an internal cavity, and two shells disposed inside the cavity, each capable of rotating about its own central axis. The invention utilizes the rotation of the shells around their central axes to move a first and second protrusion along the central axis of the shells, causing them to protrude a certain distance from the surface of the shells. This results in an uneven electrode surface formed by the three components. By gradually adjusting the voltage and observing the current change between a pair of electrodes, the device can detect the voltage at which SF6 gas breaks down and loses its insulating properties. This design, which creates an uneven electrode surface, accurately reflects the usage scenario, ensuring the accuracy of the test results and enabling the safe use of SF6 gas.

Description

Technical Field

[0001] This invention relates to the field of simulation verification device technology, and in particular to an environmentally friendly insulating gas simulation verification device. Background Technology

[0002] The environmentally friendly insulating gas simulation verification device is an important tool for simulating and verifying the performance and safety of environmentally friendly insulating gases used in electrical equipment (such as SF6 substitute gases used in gas-insulated switchgear (GIS)). This device is primarily used to test and verify the electrical insulation performance parameters of insulating gases to ensure they meet safety requirements in practical applications.

[0003] Existing simulation verification devices inject SF6 gas into an observable sealed environment and then pressurize two electrodes within the sealed environment using an external pressurizing device. They then observe changes in the current between the two electrodes under different voltages to determine whether the SF6 gas has been broken down by high voltage. However, existing electrode surfaces are smooth. If the electrode surface were perfectly smooth and flat, the electric field lines would be uniformly parallel. In this case, the stress on the gas molecules would be uniform, requiring a high voltage to trigger electron avalanche and lead to breakdown. In actual use environments, however, the connecting electrodes are typically composed of multiple strands of wire and electrode posts. The surfaces of these wires and posts are not smooth; the electrode surfaces are rough or have protrusions. These microscopic protrusions can cause a sharp increase in local electric field strength, thus breaking down the SF6 gas. Therefore, existing electrodes cannot accurately simulate and verify the breakdown voltage of SF6 gas, leading to inaccurate test results and affecting the safe use of SF6 gas in the future.

An external power supply is electrically connected to the housing, the first and second protrusions, and the three components are energized with voltage. The voltage is then gradually adjusted, and the current change between a pair of electrodes is observed. This allows the detection of the voltage at which SF6 gas breaks down and loses its insulating properties.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] To test and verify the insulation performance of SF6 gas under a high-voltage electric field when the electrode surface is uneven, such as... Figure 1 , Figure 2 and Figure 3 As shown, this invention proposes an environmentally friendly insulating gas simulation verification device, comprising: a box 100, two shells 400, a first tray 1600, and a second tray 1700. Specifically, the box 100 has an internal cavity, and the two shells 400 are disposed inside the cavity and symmetrically arranged such that the end faces of the two shells 400 are aligned. Wherein, as... Figure 4 As shown, a second cavity 410 is formed inside the two housings 400. The first disk 1600 and the second disk 1700 are both disposed inside the second cavity 410, and the first disk 1600 and the second disk 1700 are arranged on the same axis. Figure 5 and Figure 12 As shown, a plurality of first protrusions 1620 are provided on one side of the outer surface of the first disk 1600, and a plurality of second protrusions 1720 are provided on one side of the outer surface of the second disk 1700. One end of each of the second protrusions 1720 penetrates the end face of one side of the housing 400. The plurality of first protrusions 1620 are respectively inserted into the interior of the plurality of second protrusions 1720. When the device is not in use, the ends of the first protrusions 1620 and the second protrusions 1720 are flush, and the ends of both are also flush with the outer surface of the housing 400. The housing 400, the first protrusions 1620 and the second protrusions 1720 form the electrodes required for detection, and the electrodes are as follows: Figure 3The diagram shows a pair of electrodes with a fixed spacing between them. When the device is in use, the two housings 400 can rotate around their own central axis, causing the first disk 1600 and the second disk 1700 to rotate with the housings 400. The first protrusion 1620 and the second protrusion 1720 are configured such that when the housings 400 rotate around their own central axis, they move along the central axis of the housings 400, causing the first protrusion 1620 and the second protrusion 1720 to protrude from the housings 400. The surface of the three electrodes is uneven due to a distance between them. An external power supply is electrically connected to the housing 400, the first protrusion 1620 and the second protrusion 1720, so that voltage is applied to the three electrodes. The voltage is then gradually adjusted, and the current change between a pair of electrodes is observed. This allows the detection of the voltage at which SF6 gas breaks down and loses its insulating properties. This setting makes the surface of the detection electrodes uneven, which can truly reflect the usage scenario, ensure the accuracy of the detection results, and enable the safe use of SF6 gas in the future.

[0022] In this embodiment, in order to enable the first protrusion 1620 and the second protrusion 1720 to move along the central axis of the housing 400 when the housing 400 rotates, thereby protruding a certain distance from the surface of the housing 400, such as... Figure 6 , Figure 7 and Figure 13 As shown, an arc-shaped piece 700 is provided inside the second cavity 410. The arc-shaped piece 700 is fixedly positioned inside the second cavity 410. A first guide groove 710 and a second guide groove 720 are formed on the circumferential surface of the arc-shaped piece 700. A first guide post 1610 is fixedly connected to the outer circumferential surface of the first disk 1600, and a second guide post 1710 is fixedly connected to the outer circumferential surface of the second disk 1700. The first guide post 1610 is slidably installed with the inner wall of the first guide groove 710, and the second guide post 1710 is slidably installed with the inner wall of the second guide groove 720. Because the arc-shaped piece 700... The position of 00 is fixed. When the first disc 1600 and the second disc 1700 rotate with the rotation of the housing 400, they will cause the first guide post 1610 to slide relative to the first guide groove 710. At the same time, they will cause the second guide post 1710 to slide relative to the inner wall of the second guide groove 720. Because the first guide groove 710 and the second guide groove 720 are inclined on the arc plate 700, the first protrusion 1620 and the second protrusion 1720 will move along the central axis of the housing 400 through the first disc 1600 and the second disc 1700, thereby protruding a certain distance from the surface of the housing 400.

[0023] It should be noted that the center of the arc plate 700 is located at the same center as the first plate 1600 and the second plate 1700, and is located on the central axis of the housing 400, thus ensuring that the first plate 1600 and the second plate 1700 can move correctly.

[0024] In this embodiment, in order to drive the housing 400 to rotate, such as Figure 3 and Figure 6 As shown, a rotating rod 300 is fixedly installed on the other end face of the housing 400. One end of the rotating rod 300 penetrates the outer surface of the box 100. The rotating rod 300 is rotatably installed with the box 100. A handle is provided at the end of the rotating rod 300 that penetrates the box 100. The operator can manually turn the handle to drive the rotating rod 300 to rotate, thereby driving the housing 400 to rotate. The rotation range of the rotating rod 300 is determined by the length range of the first guide groove 710 and the second guide groove 720.

[0025] In this embodiment, in order to fix the arc-shaped piece 700 in a fixed position inside the second cavity 410, such as... Figure 4 , Figure 7 and Figure 8 As shown, the rotating rod 300 has a first cavity 310 at one end near the housing 400, which is connected to the second cavity 410. An opening 320 is formed on the outer circumferential surface of the rotating rod 300, which is connected to the first cavity 310. A column 500 is fixedly installed on the bottom wall of the receiving cavity of the box 100. A connecting rod 520 is fixedly installed at the top of the column 500. A hollow rod 600 is fixedly installed through the opening 320 at the top of the connecting rod 520. The hollow rod 600 is disposed inside the first cavity 310, and one end of the hollow rod 600 is fixedly connected to the outer surface of the arc plate 700 through the first cavity 310. This design allows the arc-shaped piece 700 to be fixedly installed in a fixed position inside the second cavity 410. Simultaneously, the opening 320 prevents interference with the rotation of the rotating rod 300. Since SF6 gas is present during testing, and the first cavity 310 is connected to the second cavity 410, residual air and other gases may remain inside. To prevent gas leakage into the containment cavity and contamination of the SF6 gas, a fixing ring 510 is fixedly installed at the top of the column 500. The fixing ring 510 is fitted onto the outer circumference of the rotating rod 300 and completely covers the opening 320, sealing the opening 320 and preventing other gases from contaminating the SF6 gas.

[0026] In this embodiment, in order to detect the differences in the breakdown voltage of SF6 gas when the size of the protrusions on the electrode surface varies, and to make the detection results more realistic and accurate, such as... Figure 13As shown, the first guide groove 710 is composed of a first groove 711 and a second groove 712, and the second guide groove 720 is composed of a third groove 721 and a fourth groove 722. The first groove 711 and the third groove 721 are arranged parallel to each other. It should be noted that the first groove 711 and the second groove 712 have the same dimensional parameters, similar to an isosceles triangle. The third groove 721 and the fourth groove 722, wherein the central axis of the fourth groove 722 is located on the same plane as the radius of the arc plate 700. With this arrangement, when the housing 400 rotates in one direction, that is, when the first guide post 1610 and the second guide post 1710 slide along the first groove 711 and the third groove 721 respectively, the first protrusion 1620 and the second... The protrusion 1720 moves simultaneously along the central axis of the housing 400. Conversely, when the housing 400 rotates in the other direction, that is, when the first guide post 1610 and the second guide post 1710 slide along the second groove 712 and the fourth groove 722 respectively, the first protrusion 1620 will move along the central axis of the housing 400, while the second protrusion 1720 remains stationary. The end face of the second protrusion 1720 is flush with the surface of the housing 400, and the first protrusion 1620 protrudes a distance from the surface of the housing 400. With this setting, the size of the protruding part on the surface of the housing 400 can be adjusted according to the detection requirements, thereby detecting the differences in the breakdown voltage of SF6 gas under different sizes of protrusions on the electrode surface.

[0027] In this embodiment, because the first guide post 1610 and the second guide post 1710 protrude a certain distance from the surface of the housing 400 by rotating the housing 400, in order to ensure that the operator can rotate the housing 400 to the set position and to avoid the distance between the first guide post 1610 and the second guide post 1710 protruding from the surface of the housing 400 being too small, such as... Figure 10 and Figure 11As shown, two countersunk holes 511 are symmetrically formed on the outer circumference of the fixing ring 510. A slider 1200 is slidably mounted on the inner wall of each of the two countersunk holes 511. A column 1210 is fixedly connected to one end of the slider 1200 near the hollow rod 600, and a second spring 1300 is fixedly connected to the other end of the slider 1200. A stop block 1400 is fixedly connected to the inner wall of the countersunk hole 511, and the other end of the second spring 1300 is fixedly connected to the outer surface of the stop block 1400. The inner wall of the hollow rod 600... A sliding rod 800 is slidably inserted. One end of the sliding rod 800 passes through the second cavity 410 and is fixedly connected to the rotation center of the first disk 1600. The other end of the sliding rod 800 passes through the inner wall of the hollow rod 600 and is fixedly installed with a block 900. A first square hole is opened inside the block 900. A square rod 1000 is slidably inserted into the inner wall of the first square hole. A first top head 1010 is fixedly installed at the top of the square rod 1000 through the square hole. A first... Spring 1100, the top end of the first spring 1100 is fixedly connected to the outer surface of the first top head 1010, the bottom end of the first spring 1100 is fixedly connected to the top end of the block 900, and the outer surface of the first top head 1010 abuts against the bottom end of the column 1210. When the housing 400 rotates, it drives the slide rod 800 to rotate through the first disc 1600, and the slide rod 800 drives the block 900 to rotate. The block 900, through the square rod 1000, drives the outer surface of the first top head 1010 to abut against the bottom end of the column 1210. The first pusher 1010 has an arc-shaped design. When the highest point of the arc contacts the bottom of the column 1210, it pushes the column 1210 away from the column 500, thereby causing the slider 1200 to slide away from the column 500. The operator can visually observe the position change of the slider 1200 to determine whether the housing 400 has rotated to the correct position. When the device is no longer needed, rotating the housing 400 back to the starting position resets the slider 1200 under the force of the second spring 1300. It should be noted that because the first disc 1600 can move away from the column 500 along the central axis of the housing 400 when the housing 400 rotates, the length of the first pusher 1010 needs to be considered in the actual design to ensure that the first pusher 1010 can hold the end of the column 1210.

[0028] In this embodiment, to ensure that the highest point of the arc surface of the first top head 1010 can completely abut the end of the column 1210, and to further ensure that the housing 400 rotates into place, such as... Figure 9 and Figure 11As shown, the bottom end of the square rod 1000 penetrates the outer surface of the block 900 and is fixedly installed with a second top head 1020. A second square hole is opened inside the column 500, and a square electrode rod 1500 is fixedly inserted between the inner walls of the second square hole. The top end of the square electrode rod 1500 penetrates the outer surface of the column 500 and is spaced from the second top head 1020. The bottom end of the column 500 penetrates the outer surface of the box 100, and the bottom end of the square electrode rod 1500 penetrates the bottom end of the column 500. When the first top head 1020... When the highest point of the arc surface 10 completely abuts against the end of the column 1210, it will press the square rod 1000 downward, thereby causing the second top head 1020 to abut against the top of the square electrode rod 1500, so that the square electrode rod 1500 is electrically connected to the block 900 through the second top head 1020 and the square rod 1000. The block 900 is electrically connected to the first plate 1600, the second plate 1700 and the housing 400 through the slide rod 800. In actual use, the external power supply device is electrically connected to the square electrode rod 1500 through a cable.

[0029] In this embodiment, in order to allow SF6 gas to enter and exit normally inside the cavity of the housing 100, such as Figure 1 As shown, a gas control valve 200 is fixedly connected to the outer surface of the box 100, and the gas control valve 200 is connected to the receiving cavity of the box 100.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
