[0002] A transformer is a static electrical device used to convert AC voltage and current to transmit AC power. It achieves power transmission based on the principle of electromagnetic induction. Transformers can be divided into power transformers, test transformers, instrument transformers, and special-purpose transformers based on their uses. Power transformers are essential equipment for power transmission and distribution, and power distribution to power users. To ensure the safe use of transformer insulating oil, it is often necessary to test the electrical properties of the transformer insulating oil. When testing the transformer insulating oil, an integrated testing device needs to pass high voltage electricity into the transformer insulating oil and use the high voltage electricity to test the transformer insulating oil. During the testing process, the temperature of the transformer insulating oil rises after the high voltage is passed through.

[0042] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0043] Reference below Figures 1-11 A feeder for an air cushion belt conveyor according to an embodiment of the present invention is described.

[0044] like Figures 1-11 As shown, the integrated detection device 100 based on the DCS monitoring system 62 according to the embodiment of the present invention includes: a box 10, a detection component, an oil cup 61 and a sealing component. The box 10 is provided with a receiving cavity; the detection component is provided in the receiving cavity and is installed in the box 10. The detection component includes a pressure plate 25 and an electrode member 26. The pressure plate 25 is arranged in the up and down direction (such as Figure 2The electrode member 26 extends in the up-down direction and the upper end is connected to the pressure plate 25; the oil cup 61 is arranged in the accommodating cavity and is located at the lower side of the detection component, and the opening of the oil cup 61 faces upward; the sealing component is arranged on the pressure plate 25, and the sealing component and the pressure plate 25 cooperate to seal the opening of the oil cup 61, and the electrode member 26 extends into the oil cup 61.

[0045] In this embodiment, the detection component includes a pressure plate 25 and an electrode member 26. The pressure plate 25 can move in the up and down directions. The oil cup 61 is arranged on the lower side of the pressure plate 25 and the opening is facing upward. The electrode member 26 extends into the oil cup 61, which can well meet the detection needs of the transformer insulating oil. For example, when the integrated detection device performs the detection operation, the oil cup 61 contains the transformer insulating oil to be tested, and the pressure plate 25 can move toward the oil cup 61 so that the electrode member 26 extends into the oil cup 61. The sealing assembly cooperates with the pressure plate 25 to cover the opening of the oil cup 61, thereby sealing the oil cup 61 to prevent external air from entering the oil cup 61. High voltage electricity can be passed into the transformer insulating oil through the electrode member 26, so that the integrated detection device 100 can detect the transformer insulating oil.

[0046] In this embodiment, the box 10 is provided with a accommodating cavity, and the detection component is arranged in the accommodating cavity and installed on the box 10. The structure is simple, and a good layout position and space can be provided for the installation layout of the detection component. The box 10 can play a good protective role for the detection device and the oil cup 61, etc. At the same time, when the operator is performing the inspection, if the transformer insulating oil burns, etc., the box 10 can play a good isolation and protection role for the operator, thereby making the integrated detection device 100 safer during the inspection.

[0047] In this embodiment, the sealing assembly includes: an annular member 301, an annular pressure plate 302 and a sealing member 303. The annular member 301 is formed with an annular groove 3011 with an opening facing downward; the annular pressure plate 302 is arranged in the annular groove 3011 and abuts against the open end edge of the oil cup 61; the sealing member 303 is arranged in the annular groove 3011 and is sealed between the annular pressure plate 302 and the side wall of the annular groove 3011. The sealing member 303 can be elastically deformed in the radial direction of the annular member 301. When the annular pressure plate 302 is configured to be pressed against the open end edge in the up and down directions, the annular pressure plate 302 is pressed against the sealing member 303 in the radial direction of the annular member 301.

[0048] The sealing assembly in this embodiment is provided on the pressure plate 25 and cooperates with the pressure plate 25 to cover the opening of the oil cup 61. The sealing assembly is arranged on the side of the pressure plate 25 facing the oil cup 61. The annular member 301 is formed with an annular groove 3011 facing the opening. The annular pressure plate 302 is provided in the annular groove 3011 and abuts against the open end edge of the oil cup 61. For example, the annular member 301 can be fixedly connected to the pressure plate 25. When the pressure plate 25 moves toward the oil cup 61, the annular pressure plate 302 can extend into a ring shape along the circumference of the oil cup 61 and abut against the open end edge of the oil cup 61, so that the oil cup 61 is sealed at the open end edge by the abutment of the annular pressure plate 302. For example, after the pressure plate 25 cooperates with the sealing assembly to seal the oil cup 61, the air in the oil cup 61 can be evacuated and replaced with oxygen-free gas to avoid combustion of the transformer insulating oil due to residual oxygen in the oil cup 61 after high voltage electricity is passed through. For example, the integrated detection device 100 can be provided with an air pump 471 to pass oxygen-free gas such as carbon dioxide into the oil cup 61 to expel the original air from the oil cup 61.

[0049] When the annular pressure plate 302 abuts against the oil cup 61, a part of the annular pressure plate 302 in the radial direction of the annular member 301 is located on the inner side of the oil cup 61 and cooperates with the pressure plate 25 to seal the opening of the oil cup 61, and the other part of the annular pressure plate 302 is located on the outside of the oil cup 61. It can be understood that after the pressure plate 25 presses against the oil cup 61 so that the annular pressure plate 302 abuts against the open end of the oil cup 61, when the seal between the annular pressure plate 302 and the side wall of the annular groove 3011 is not good, external air can enter the oil cup 61 along the gap between the part of the annular pressure plate 302 on the outside of the oil cup 61 and the side wall of the annular groove 3011, the gap between the annular pressure plate 302 and the annular groove 3011, and the gap between the part of the annular pressure plate 302 on the inside of the oil cup 61 and the side wall of the annular groove 3011, thereby causing the transformer insulating oil to burn when the integrated detection device 100 performs the detection operation, thereby affecting the safety of the detection operation.

[0050] In this embodiment, the seal 303 is elastically deformable in the radial direction of the annular member 301. When the annular pressure plate 302 is configured to be pressed against the open end of the oil cup 61 in the up and down directions, the annular pressure plate 302 is pressed against the seal 303 in the radial direction of the annular member 301, so that the annular pressure plate 302 can obtain a good extrusion sealing effect in the radial direction of the annular member 301 through the seal 303 and the side wall of the annular groove 3011. The seal 303 stably and reliably abuts and seals with the side wall of the annular groove 3011 and the annular pressure plate 302 through elastic deformation, thereby effectively cutting off the path of external air entering the oil cup 61 from the annular pressure plate 302 and the annular groove 3011, so that the oil cup 61 obtains a more stable and reliable sealing effect, thereby effectively avoiding the burning of transformer insulating oil when the integrated detection device 100 is performing detection operations, and ensuring the safety of the integrated detection device 100 during detection operations.

[0051] According to the integrated detection device 100 based on the DCS monitoring system 62 according to an embodiment of the present invention, a sealing component is provided, and the sealing component includes an annular member 301, an annular pressure plate 302 and a sealing member 303. The sealing member 303 is arranged in the annular groove 3011 of the annular member 301 and is sealed between the annular pressure plate 302 and the side wall of the annular groove 3011. The annular pressure plate 302 is pressed against the sealing member 303 in the radial direction of the annular member 301, so that the oil cup 61 can obtain a stable and reliable sealing effect, thereby effectively avoiding the situation where the transformer insulating oil burns when the integrated detection device 100 is performing detection operations, so that the safety of the integrated detection device 100 during detection operations is well guaranteed.

[0052] In some embodiments of the present invention, Figure 8 and Figure 11 As shown, the sealing member 303 may include: a fixing portion 3033 , a first sealing lip 3031 and a second sealing lip 3032 .

[0053] Specifically, the fixing portion 3033 is connected to the side wall of the annular groove 3011; the lower end of the first sealing lip 3031 is connected to the lower end of the fixing portion 3033, and the upper end of the first sealing lip 3031 extends obliquely from the bottom to the top along the radial direction of the annular member 301 away from the fixing portion 3033, and the first sealing lip 3031 is suitable for abutting against the side wall of the annular pressure plate 302; the second sealing lip 3032 is arranged between the first sealing lip 3031 and the fixing portion 3033, one end of the second sealing lip 3032 is connected to the upper end of the fixing portion 3033, and the other end of the second sealing lip 3032 is connected to the first sealing lip 3031, and the second sealing lip 3032 extends obliquely from the bottom to the top along the radial direction of the annular member 301 toward the fixing portion 3033.

[0054] The cam 3032 is provided on the upper edge of the first sealing lip 3031 and the lower edge of the first sealing lip 3032, so that the cam 3032 is in a stable state when the cam 3032 is in a stable state when the cam 3032 is in a stable state when the cam 3032 is in a stable state when the cam 3032 is in a stable state when the cam 3032 is in a stable state when the cam 3032 is in a stable state The sealing lip 3031 is between the sealing lip 3031 and the fixed part 3033, and one end of the second sealing lip 3032 is connected to the upper end of the fixed part 3033, and the other end of the second sealing lip 3032 is connected to the first sealing lip 3031, so that the first sealing lip 3031 can be more stably connected to the fixed part 3033 through the second sealing lip 3032, and the second sealing transmission extends obliquely from bottom to top toward the fixed part 3033, which can cooperate with the fixed part 3033 to provide a good support for the first sealing lip 3031 in the radial direction of the annular member 301, so that when the sealing member 303 and the annular pressure plate 302 are pressed in the radial direction of the annular member 301, the sealing member 303 can stably and reliably abut and seal against the annular pressure plate 302, so that the sealing member 303 has a good sealing effect on the annular pressure plate 302 and the side wall of the annular groove 3011.

[0055] In one embodiment of the present invention, Figure 8 As shown, the annular pressure plate 302 can be formed with a first inclined surface 3021 on both sides of the radial direction of the annular member 301, and the first inclined surface 3021 extends obliquely in the radial direction of the annular member 301 from bottom to top, and a second inclined surface is formed on the surface of the first sealing lip 3031 facing away from the fixed portion 3033, wherein one of the first inclined surface 3021 and the second inclined surface is provided with a locking protrusion 30211 and the other is provided with a locking groove 30311, and when the annular pressure plate 302 moves toward the sealing member 303 in the up and down directions, the locking protrusion 30211 is suitable for extending into the locking groove 30311.

[0056] In this embodiment, the annular pressure plate 302 is formed with a first inclined surface 3021 on both sides of the radial direction of the annular member 301. The first inclined surface 3021 extends in an upward direction along the radial direction of the annular member 301, and the width of the annular pressure plate 302 gradually decreases from bottom to top in the radial direction of the annular member 301. A second inclined surface is formed on the surface of the first sealing lip 3031 on the side away from the fixing portion 3033. For example, the second inclined surface extends in an upward direction along the radial direction of the annular member 301 away from the fixing portion 3033. The second inclined surface can cooperate well with the first inclined surface 3021 to make the annular pressure plate 302 02 and the seal 303 have a larger sealing abutment area, which makes the sealing effect between the seal 303 and the annular pressure plate 302 better, and plays a good guiding role in the relative movement of the annular pressure plate 302 and the seal 303 in the up and down directions. Specifically, the two side walls of the annular groove 3011 are respectively arranged with seals 303, and a sealed space can be formed between the two seals 303. The annular pressure plate 302 can stably move into the sealed space under the guidance of the first inclined surface 3021 and the second inclined surface, so that the first inclined surface 3021 of the annular pressure plate 302 and the second inclined surface of the seal 303 can reliably abut and seal.

[0057] In this embodiment, a latching protrusion 30211 is provided on one of the first inclined surface 3021 and the second inclined surface, and a latching groove 30311 is provided on the other. When the annular pressure plate 302 moves downward along the up and down directions with the seal 303, the latching protrusion 30211 is suitable for extending into the latching groove 30311. The structure is simple. The setting of the latching protrusion 30211 and the latching groove 30311 can increase the contact area when the first inclined surface 3021 and the second inclined surface are abutted and matched, and can increase the extension length of the first inclined surface 3021 and the second inclined surface in the up and down directions, thereby further increasing the difficulty of external air entering the oil cup 61 through the annular pressure plate 302 and the seal 303, so that the sealing effect of the seal 303 and the annular pressure plate 302 is further improved.

[0058] For example, refer to Figure 7 and Figure 8 As shown, the annular pressure plate 302 is movable between an initial position and a sealing position. In the initial position, the annular pressure plate 302 is located on the lower side of the sealing member 303. In the sealing position, the annular pressure plate 302 and the sealing member 303 are arranged opposite to each other in the radial direction of the annular member 301. In this way, when the annular pressure plate 302 moves between the initial position and the sealing position, the annular pressure plate 302 can play a buffering role through the moving friction with the sealing member 303, so that when the pressure plate 25 is pressed toward the oil cup 61, the annular pressure plate 302 can be gradually pressed against the open end of the oil cup 61, thereby reducing the greater impact force on the oil cup 61 caused by the direct pressing of the annular pressure plate 302 and the oil cup 61, so that the integrated detection device 100 can operate more stably.

[0059] In one embodiment of the present invention, Figure 8 and Figure 11 As shown, the seal 303 may further include a reinforcement frame 3036, which is embedded in the fixing portion 3033. This can improve the structural strength of the fixing portion 3033, so that the seal 303 can be more stably and reliably fixed to the side wall of the annular member 301, thereby allowing the seal 303 to stably and reliably perform a sealing function.

[0061] In this embodiment, the sealing member 303 further includes a first elastic portion 3034 and a second elastic portion 3035. The first elastic portion 3034 is arranged between the first sealing lip 3031 and the second sealing lip 3032 and is located on one side of the second sealing lip 3032 in the up-down direction. The second elastic portion 3035 is arranged between the first sealing lip 3031, the second sealing lip 3032 and the fixing portion 3033. The second elastic portion 3035 is located on the other side of the second sealing lip 3032 in the up-down direction. The structure is simple and the arrangement is reasonable. The first elastic portion 3034 and the second elastic portion 3035 can cooperate with the second sealing lip 3032 to better support the first sealing lip 3031, so that the annular pressure plate 302 and the sealing member 303 can be more stably and reliably abutted and pressed against each other in the radial direction of the annular member 301, and the elastic deformation performance of the sealing member 303 can be greatly improved, so that the sealing member 303 can have a better sealing effect, and the sealing assembly can have a better sealing effect on the oil cup 61.

[0062] In some examples of the present invention, Figure 8 As shown, the sealing assembly can also include: a first pusher 304, a second pusher 305, a first support plate 308 and an airbag 315, the first pusher 304 is connected to the annular pressure plate 302, and the first pusher 304 is arranged on the side of the annular pressure plate 302 facing the bottom of the annular groove 3011; the second pusher 305 is arranged on both sides of the first pusher 304 in the radial direction of the annular member 301, the second pusher 305 extends along the radial direction of the annular member 301 and abuts against the second pusher 305, and the first pusher 304 and the second pusher 305 can move relative to each other in the up and down directions.

[0063] The first support plate 308 and the airbag 315 are both arranged in the annular groove 3011 and are located on the side of the annular pressure plate 302 facing the bottom of the annular groove 3011. The first support plate 308 extends in the up and down directions. The airbag 315 is arranged between the first support plate 308 and the side wall of the annular groove 3011. The second pushing member 305 and the first support plate 308 abut against the radial direction of the annular member 301, wherein the first pushing member 304 is respectively formed with third inclined surfaces 3042 on both sides of the radial direction of the annular member 301. The two third inclined surfaces 3042 extend obliquely toward each other along the radial direction of the annular member 301 from bottom to top. The first elastic portion 3034 has a cavity 30341, and the airbag 315 is connected to the cavity 30341.

[0064] In this embodiment, the first pusher 304 is connected to the annular pressure plate 302 and is arranged on one side of the annular pressure plate 302 facing the bottom of the annular groove 3011. A third inclined surface 3042 is formed on both sides of the radial direction of the annular member 301. The two third inclined surfaces 3042 extend toward each other in the radial direction of the annular member 301 from bottom to top. In the radial direction of the annular member 301, the width of the first pusher 304 gradually decreases from bottom to top. The second pusher 305 is arranged on both sides of the first pusher 304 in the radial direction of the annular member 301. The second pusher 305 and the third inclined surface 3042 are respectively formed on both sides of the radial direction of the annular member 301. Abutment. When the annular pressure plate 302 moves in the up and down directions, the first push member 304 can move toward the bottom of the annular groove 3011 or toward the oil cup 61 relative to the second push member 305. When the first push member 304 moves toward the bottom of the annular groove 3011 relative to the second push member 305, the annular pressure plate 302 can be pressed toward the oil cup 61, and the width of the part where the first push member 304 and the second push member 305 cooperate and abut against each other gradually increases, so that the second push member 305 moves along the radial direction of the annular member 301 toward the side wall of the annular groove 3011 under the action of the first push member 304.

[0065] In this embodiment, the first support plate 308 extends in the up-down direction, the second pusher 305 abuts against the first support plate 308 in the radial direction of the ring 301, the airbag 315 is arranged between the first support plate 308 and the side wall of the annular groove 3011, and the airbag 315 is connected to the first elastic continuous cavity 30341. When the second pusher 305 moves along the radial direction of the ring 301 toward the side wall of the annular groove 3011, the first support plate 308 can be pushed by the second pusher 305 in the radial direction of the ring 301. The airbag 315 is squeezed so that the gas in the airbag 315 is pressed into the cavity 30341 of the first elastic part 3034, which can further enhance the supporting effect of the first elastic part 3034, so that the first elastic part 3034 can better support the first sealing lip 3031 in the radial direction of the annular part 301, so that the sealing part 303 and the annular pressure plate 302 can be more tightly and reliably abutted and sealed in the radial direction of the annular part 301, thereby further enhancing the sealing effect of the sealing part 303 and the annular pressure plate 302.

[0066] In this embodiment, the first support plate 308 can evenly transmit the force applied by the second pusher 305 to the airbag 315, so that the airbag 315 can be stably compressed to inflate the cavity 30341 of the first elastic portion 3034, thereby allowing the sealing assembly to operate more stably.

[0067] In one example of the present invention, Figure 8 As shown, the first pusher 304 may be provided with a first cavity 3041 , and the sealing assembly may further include: a first sliding plate 306 , a connecting rod 310 and a guide member 311 , a first elastic member 312 , a second elastic member 313 , a second sliding plate 307 and a second support plate 309 .

[0068] Specifically, the first sliding plate 306 is arranged in the annular groove 3011 and is located on the side of the first pushing member 304 facing the bottom of the annular groove 3011. In the up and down directions, the first sliding plate 306 abuts against the first support plate 308 and the airbag 315; the guide member 311 is arranged in the first cavity 3041, and the guide member 311 slides with the side wall of the first cavity 3041 along the up and down directions. The connecting rod 310 extends along the up and down directions and is connected to the first sliding plate 306 and the guide member 311; the first elastic member 312 is sleeved on the connecting rod 310, and the first elastic member 312 can be elastically deformed in the up and down directions. The two ends of the first elastic member 312 abut against the first sliding plate 306 and the first pushing member 304 respectively; the second elastic member 313 is arranged in the first cavity 3041 and is located on the side of the guide member 311 away from the connecting rod 310. The second elastic member 313 can be elastically deformed in the up and down directions.

[0069] In this embodiment, the first sliding plate 306 is arranged in the annular groove 3011 and is located on the side of the first pushing member 304 facing the bottom of the annular groove 3011. A first elastic member 312 is provided between the first sliding plate 306 and the first pushing member 304. The first sliding plate 306 abuts against the first support plate 308 and the airbag 315 in the up and down directions. The connecting rod 310 extends in the up and down directions and is connected to the first sliding plate 306 and the guide member 311. The first elastic member 312 is sleeved on the connecting rod 310. For example, the first pushing member 304 can be provided with a through hole, which is connected to the first cavity 3041. The connecting rod 310 can extend from the through hole into the first cavity 3041 and be connected to the guide member 311. The second elastic member 313 is arranged in the first cavity 3041 and is located on the side of the guide member 311 away from the connecting rod 310. When the first push member 304 moves in the up and down directions toward the first sliding plate 306, the guide member 311 cooperates with the first sliding plate 306 and the connecting rod 310 to press against the second elastic member 313, and the first push member 304 presses against the first elastic member 312. That is, when the sealing assembly cooperates with the pressure plate 25 to cover the oil cup 61, the first elastic member 312 and the second elastic member 313 are gradually compressed, which can play a good buffering role, so that the annular pressure plate 302 can be more smoothly pressed and sealed with the oil cup 61, so that the integrated detection device 100 can operate more stably during the detection operation.

[0070] In this embodiment, the guide member 311 slides with the side wall of the first cavity 3041, so that the relative movement of the first push member 304 and the second push member 305 in the up and down directions can be more stable and reliable, and the annular pressure plate 302 can move more stably and reliably relative to the sealing member 303 in the up and down directions to achieve stable sealing contact.

[0071] In this embodiment, the first sliding plate 306 abuts against the first support plate 308 and the airbag 315 in the up and down directions. For example, the first support plate 308 and the airbag 315 can be arranged between the first sliding plate 306 and the seal 303 in the up and down directions. The first support plate 308 and the airbag 315 can be stably arranged in the annular groove 3011 under the support of the seal 303, so that the first sliding plate 306 can be stably arranged in the annular groove 3011 under the support of the first support plate 308, which facilitates the assembly of the first sliding plate 306, the first support plate 308 and the airbag 315 in the annular groove 3011.

[0072] In this embodiment, the second sliding plate 307 is arranged in the annular groove 3011 and is located on the upper side of the first sliding plate 306. A third elastic member 314 is connected between the second sliding plate 307 and the first sliding plate 306. The third elastic member 314 can be elastically deformed in the up and down directions. The second support plate 309 extends in the up and down directions. In the radial direction of the annular member 301, the second support plate 309 abuts against the side wall of the annular groove 3011 and the first sliding plate 306. The second sliding plate 307 abuts against the second support plate 309 in the up and down directions. A pushing portion is formed at the lower end of the support plate 309, which abuts against the airbag 315 and the side wall of the annular groove 3011 in the radial direction of the annular member 301, and a fourth inclined surface is formed on the pushing portion, which extends obliquely from top to bottom along the radial direction of the annular member 301 toward the side wall of the annular groove 3011. The second support plate 309 is configured to squeeze the airbag 315 when the second sliding plate 307 and the first sliding plate 306 approach each other in the up and down directions, so that the gas in the airbag 315 is pressed into the cavity 30341 of the first elastic portion 3034.

[0073] In this embodiment, the second sliding plate 307 is arranged in the annular groove 3011 and is located on the upper side of the first sliding plate 306. A third elastic member 314 is connected between the second sliding plate 307 and the first sliding plate 306. The second support plate 309 extends in the up-down direction and abuts the second sliding plate 307 in the up-down direction. A pushing portion is formed at the lower end of the second support plate 309, and the pushing portion abuts the airbag 315 and the side wall of the annular groove 3011 in the radial direction of the annular member 301. When the second sliding plate 307 and the first sliding plate 306 approach each other in the up-down direction, the second support plate 309 squeezes the airbag 315 so that the gas in the airbag 315 is pressed into the cavity 30341 of the first elastic portion 3034.

[0074] For example, when the pressure plate 25 is pressed toward the oil cup 61, the annular pressure plate 302 can move from the initial position toward the sealing position under the interaction with the oil cup 61, thereby gradually abutting and sealing with the sealing member 303, and the second sealing lip 3032, the first elastic portion 3034 and the second elastic portion 3035 of the sealing member 303 cooperate to support the first sealing lip 3031, so that the first sealing lip 3031 is stably abutted and pressed against the annular pressure plate 302, and the first pushing member 304 is pushed down by the annular pressure plate 302, and the second pushing member 305 is pushed along the radial direction of the annular member 301, so that the first support plate 308 squeezes the airbag 315, and at the same time, the second sliding plate 307 can move toward the annular pressure plate 302 relative to the first sliding plate 306. The second support plate 309 moves to squeeze the airbag 315, so that the airbag 315 can have a larger compression deformation under the joint extrusion of the first support plate 308 and the second support plate 309, so that the airbag 315 can fill more gas into the cavity 30341 of the first elastic part 3034, so that the first elastic part 3034 can have a better supporting effect, so that the abutment seal between the seal 303 and the annular pressure plate 302 is tighter and more reliable, and the airbag 315 can better overcome the extrusion force on the first elastic part 3034 formed when the annular pressure plate 302 and the seal 303 are squeezed in the radial direction of the annular part 301, so that the gas can be filled into the cavity 30341 more stably.

[0075] In this embodiment, the pushing portion abuts against the airbag 315 and the side wall of the annular groove 3011 in the radial direction of the annular member 301, and the pushing portion is formed with a fourth inclined surface, which extends obliquely from top to bottom along the radial direction of the annular member 301 and the side wall of the annular groove 3011. The structure is simple, and the side wall can guide and limit the pushing portion. The setting of the fourth inclined surface allows the pushing portion to extend more smoothly between the airbag 315 and the side wall in the up and down directions to squeeze the airbag 315, so that the second support plate 309 can better cooperate with the operation of the airbag 315.

[0076] In some specific embodiments of the present invention, Figure 6 and Figure 8 As shown, the second sliding plate 307 cooperates with the bottom wall of the annular groove 3011 to define an air pressure chamber. The integrated detection device 100 can also include an exhaust component, which includes an air storage component 41. The air storage component 41 is arranged on the pressure plate 25. The air storage component 41 has an air storage chamber 401. The air storage chamber 401 is connected to the oil cup 61 and the air pressure chamber. The side wall of the air storage chamber 401 is provided with an air release valve 46.

[0077] In this embodiment, the second sliding plate 307 cooperates with the bottom wall of the annular groove 3011 to define an air pressure chamber. The air storage member 41 is provided on the pressure plate 25. The air storage chamber 401 of the air storage member 41 is connected to the oil cup 61 and the air pressure chamber. The side wall of the air storage chamber 401 is provided with a relief valve 46. The structure is simple and the arrangement is reasonable. It can be understood that when the integrated detection device 100 detects the transformer insulating oil in the oil cup 61, after high voltage is passed into the transformer insulating oil, when the high voltage breaks through the transformer insulating oil, the transformer insulating oil generates high temperature and boils. In this case, the air pressure in the oil cup 61 increases, thereby reducing the sealing effect of the oil cup 61. In this embodiment, the air storage cavity 401 of the air storage member 41 is connected to the oil cup 61, so that the gas in the oil cup 61 can flow into the air storage cavity 401, thereby reducing the air pressure in the oil cup 61 to a certain extent, reducing the probability of the pressure plate 25 and the sealing component being sealed along the open end of the oil cup 61 under the push of the air pressure in the oil cup 61, and allowing the pressure plate 25 and the sealing component to perform a stable and reliable sealing function during the detection process.

[0078] The air storage chamber 401 is connected to the oil cup 61 and the air pressure chamber, so that the gas in the air storage chamber 401 can enter the air pressure chamber after the air pressure increases due to the inflow of hot air. The second sliding plate 307 can move toward the first sliding plate 306 in the up and down directions under the driving action of the gas, thereby driving the second support plate 309 to squeeze the airbag 315, thereby increasing the sealing effect of the seal 303 and the annular pressure plate 302, so that the integrated detection device 100 can automatically enhance the sealing effect of the oil cup 61 as the air pressure in the oil cup 61 changes during the detection process, so that the sealing component can cooperate with the pressure plate 25 to seal the oil cup 61 more stably and reliably, further reducing the probability of external air entering the oil cup 61, so that the integrated detection device 100 can perform detection operations more safely, stably and reliably.

[0079] In this embodiment, a gas relief valve 46 is provided on the side wall of the gas storage chamber 401 so that when the gas pressure in the gas storage chamber 401 is too high, the gas can be discharged through the gas relief valve 46, thereby allowing the integrated detection device 100 to perform detection operations more stably and reliably.

[0080] In a specific embodiment of the present invention, Figure 4 、 Figure 6 and Figure 7 As shown, the air storage member 41 is provided with a first through hole 402 , and the exhaust assembly may further include: an air box 47 , a one-way valve 45 , a guide hole and a cover plate 43 , and an oil baffle 44 .

[0081] Specifically, an air pump 471 is installed in the air box 47, and the air pump 471 is configured to deliver carbon dioxide to the oil cup 61; a one-way valve 45, which is provided on the bottom wall of the air storage member 41, and the one-way valve 45 is unidirectionally conducted toward the oil cup 61; a guide block 42 and a cover plate 43, the guide block 42 is provided in the air storage chamber 401, and the guide block 42 is provided with a second through hole 421, and the second through hole 421 is communicated with the first through hole 402 and the oil cup 61, and the cover plate 43 is provided with a second through hole 421. The cover plate 43 seals the opening of the second through hole 421. The cover plate 43 is rotatably connected to the guide block 42 at one end in the radial direction of the annular member 301. The guide block 42 is formed with a guide slope 422. The guide slope 422 is formed on one side of the cover plate 43 and extends obliquely from top to bottom toward the one-way valve 45, away from the cover plate 43. The oil baffle plate 44 is disposed in the air storage chamber 401 and is located above the opening of the first through hole 402.

[0082] In this embodiment, an air pump 471 is installed in the air box 47. The air pump 471 is configured to transport carbon dioxide into the oil cup 61. After the pressure plate 25 and the sealing assembly seal the opening of the oil cup 61, the air pump 471 can be operated to fill the oil cup 61 with carbon dioxide, so that the gas containing oxygen in the oil cup 61 can flow into the gas storage chamber 401. As carbon dioxide continues to be filled, the original gas can be discharged from the gas storage chamber 401 from the air release valve 46, so that there is no oxygen in the gas storage chamber 401 and the oil cup 61, thereby effectively avoiding the burning or even explosion of the transformer insulating oil due to the presence of oxygen after the high voltage electricity breaks down, so that the safety of the integrated detection device 100 during detection operations is well guaranteed.

[0083] It is understandable that the transformer insulating oil boils after the high voltage breakdown. Since the gas storage chamber 401 is connected to the oil cup 61, the boiling transformer insulating oil may splash into the gas storage chamber 401. In this embodiment, a guide block 42 and an oil baffle 44 are provided in the gas storage chamber 401. The second through hole 421 of the guide block 42 is connected to the first through hole 402 of the gas storage member 41 and the oil cup 61, so that the gas in the oil cup 61 can enter the gas storage chamber 401 along the first through hole 402 and the second through hole 421, meeting the use needs of the gas storage member 41 and the exhaust needs of the oil cup 61. The guide block 42 is formed with a guide slope 422, which is directed from top to bottom toward the one-way valve 4 5 is extended obliquely, and the one-way valve 45 is unidirectionally conducted toward the oil cup 61. The oil baffle plate 44 is arranged on the upper side of the opening of the first through hole 402, so that the oil splashed from the first through hole 402 into the air storage chamber 401 can fall onto the guide slope 422 under the action of the oil baffle plate 44, thereby reducing the scope of oil contamination in the air storage chamber 401. The oil can flow toward the one-way valve 45 and then back into the oil cup 61 under the guidance of the guide slope 422, thereby effectively reducing the contamination of the air storage chamber 401 by the oil, so that the air storage member 41 can be better kept clean during the long-term use of the integrated detection device 100, thereby making it easier and more convenient to clean the integrated detection device 100 later.

[0084] In this embodiment, a cover plate 43 is provided at the opening of the second through hole 421. The cover plate 43 is rotatably connected to the guide block 42 and has a simple structure. It can open and disconnect the connection between the air storage chamber 401 and the oil cup 61, meet the exhaust needs of the oil cup 61, and reduce the probability of oil splashing into the air storage chamber 401.

[0085] In one embodiment of the present invention, Figure 4 As shown, the exhaust assembly may further include an air pipe 48 and a solenoid valve 49. The solenoid valve 49 is disposed on the pressure plate 25. The air pipe 48 is connected to the outlet of the air pump 471 and the solenoid valve 49. This allows the air pump 471 to deliver carbon dioxide into the oil cup 61 through the air pipe 48. The solenoid valve 49 can control the amount of carbon dioxide flowing into the oil cup 61 as needed, allowing the air pump 471 to cooperate with the air pipe 48 and the solenoid valve 49 to effectively meet the exhaust needs of the oil cup 61.

[0086] In some embodiments of the present invention, Figure 4 and Figure 11As shown, the detection component can also include: a fixing ring 21 and a fixing part, the fixing ring 21 is arranged in the accommodating cavity, the fixing ring 21 extends in the up and down directions and the upper end is fixedly connected to the box body 10, the fixing part is arranged on the radial inner side of the fixing ring 21 and slides with the fixing ring 21 in the up and down directions, the fixing part is fixedly connected to the pressure plate 25, the integrated detection device 100 also includes a driving component 50, the driving component 50 is installed on the box body 10, the driving component 50 includes a driving component 51 and a screw rod 52, the driving component 51 is transmission-connected to the screw rod 52, the screw rod 52 extends in the up and down directions, the screw rod 52 is threadedly matched with the fixing component, and the driving component 51 is suitable for driving the fixing component to move in the up and down directions through the screw rod 52, so that the pressure plate 25 is pressed toward or away from the oil cup 61.

[0087] In this embodiment, the detection component is provided with a fixing ring 21 and a fixing part. The fixing ring 21 is fixedly connected to the housing 10. The fixing part is arranged on the radial inner side of the fixing ring 21 and slides with the fixing ring 21 in the up and down directions. The fixing part is fixedly connected to the pressure plate 25. The screw rod 52 of the driving component 50 is threadedly engaged with the fixing part. When the integrated detection device 100 is operating, the driving component 51 drives the screw rod 52 to rotate, so that the fixing part moves downward in the up and down directions, thereby driving the pressure plate 25 to press against the oil cup 61, so that the sealing component can cooperate with the pressure plate 25 to cover the opening of the oil cup 61.

[0088] In this embodiment, a fixing ring 21 is provided, which can play a good guiding role in the movement of the fixing part. The driving assembly 50 is provided with a driving part 51 and a screw rod 52 for transmission connection with the fixing part. The structure is simple and the transmission is stable and reliable, so that the fixing part can move stably in the up and down directions, so that the integrated detection device 100 can operate stably to perform detection operations.

[0089] In one embodiment of the present invention, Figure 4 As shown, the fixing part may include a connecting ring 22 and a connecting plate 23. The connecting ring 22 extends in the up and down directions and its two ends are respectively connected to the pressure plate 25 and the connecting plate 23. The connecting plate 23 is threadedly engaged with the screw rod 52. The lower end of the fixing ring 21 is provided with a guide ring 24, which is fixedly connected to the fixing ring 21. The guide ring 24 is provided between the fixing ring 21 and the connecting ring 22, and the guide ring 24 abuts against the outer peripheral wall of the connecting ring 22.

[0090] In this embodiment, the fixed ring 21 is provided with a connecting ring 22 and a connecting plate 23, which has a simple structure and is convenient for transmission connection with the pressure plate 25 and the screw rod 52. The guide ring 24 can support and guide the lower end of the connecting ring 22, so that the connecting ring 22 can move more stably in the up and down directions, and can reduce the sliding matching area between the connecting ring 22 and the guide ring 24, thereby reducing friction, so that the fixed ring 21 and the connecting ring 22 can cooperate more stably and lastingly.

[0091] In some embodiments of the present invention, Figure 4 and Figure 6 As shown, the integrated detection device 100 may also include: a DCS monitoring system 62, a high-voltage power supply 63 and an intelligent circuit breaker 64, the DCS monitoring system 62 is electrically connected to the high-voltage power supply 63 and the intelligent circuit breaker 64, and the high-voltage power supply 63 is electrically connected to the electrode member 26 through the intelligent circuit breaker 64.

[0092] In this embodiment, a DCS (Distributed Control System) monitoring system is provided. The DCS monitoring system 62 is electrically connected to the high-voltage power supply 63 and the intelligent circuit breaker 64, and can monitor and control the operating status of the high-voltage power supply 63 and the intelligent circuit breaker 64 in real time, thereby further improving the safety of the integrated detection device 100 during operation. For example, the DCS monitoring system 62 can control the high-voltage power supply 63 to be turned on as needed to pass high voltage electricity into the transformer insulating oil. The voltage continues to rise until the transformer insulating oil is broken down. After the breakdown, the resistance of the transformer insulating oil drops rapidly and forms a circuit path. The intelligent circuit breaker 64 can disconnect the circuit when the current in the circuit is large, thereby effectively ensuring the circuit safety and avoiding circuit damage.

[0093] Specifically, the DCS monitoring system 62 may include an oxygen detector and a sensor to detect the gas in the gas storage chamber 401.

[0110] The drive assembly 50 includes a drive member 51 and a screw 52. The drive member 51 is mounted on the first plate. The screw 52 extends in a first direction and is in transmission connection with the drive member 51.

The high-voltage power supply 63 and the intelligent circuit breaker 64 are both mounted on the pressure plate 25.

A control panel 66 is provided on the housing 10 and can be in communication with the DCS monitoring system 62.

[0111] When the integrated detection device 100 is testing the transformer insulating oil, the operator opens the box door 111 and fills the transformer insulating oil into the oil cup 61. The operator closes the box door 111, and the DCS monitoring system 62 controls the drive assembly 50 to operate, so that the pressure plate 25 moves toward the oil cup 61. As the pressure plate 25 gradually presses against the oil cup 61, the annular pressure plate 302 gradually abuts against the open end of the oil cup 61. Under the push of the reaction force of the oil cup 61, the annular pressure plate 302 gradually presses against the sealing member 303 in the vertical direction, and the protrusion 303 is locked. 0211 is snap-fitted with the card groove 30311, and the annular pressure plate 302 is squeezed and sealed with the two sealing members 303 along the radial direction of the annular member 301. The sealing member 303 supports the first sealing lip 3031 well through the second sealing lip 3032, the first elastic part 3034 and the second elastic part 3035. The second inclined surface of the first sealing lip 3031 and the first inclined surface 3021 of the annular pressure plate 302 greatly increase the sealing abutment area and can form a greater extrusion force in the radial direction of the annular member 301.

[0112] The arrangement of the first inclined surface 3021 and the second inclined surface enables the annular pressure plate 302 and the sealing member 303 to have greater frictional force when they are in sealing contact, so that the first sealing lip 3031 and the annular pressure plate 302 can be pressed and sealed more stably and reliably. Furthermore, the first pushing member 304 follows the movement of the annular pressure plate 302 to squeeze the two second pushing members 305 toward the airbag 315, the first elastic portion 3034 elastically supports the first sealing lip 3031, and the second elastic portion 3035 elastically supports the second sealing lip 3032. The gas in the airbag 315 is continuously injected into the cavity 30341 of the first elastic portion 3034 as the second pushing member 305 is squeezed, causing the first elastic portion 3034 to expand, thereby continuously enhancing the sealing effect of the abutment between the sealing member 303 and the annular pressure plate 302, and the first elastic member 312 and the second elastic member 313 are gradually compressed to play a buffering role, preventing the annular pressure plate 302 from moving quickly in the annular groove 3011. When the annular pressure plate 302 moves to the sealing position, a stable and reliable sealing abutment is formed between the annular pressure plate 302 and the sealing member 303, thereby effectively isolating the external air and preventing the transformer insulating oil from burning or even exploding due to the high temperature generated after the breakdown current.

[0113] After the oil cup 61 and the sealing assembly are in place, the DCS monitoring system 62 controls the drive assembly 50 to stop and controls the air pump 471 to fill the oil cup 61 with carbon dioxide gas, so that the gas in the oil cup 61 flows into the gas storage chamber 401 and is discharged from the gas storage chamber 401 through the relief valve 46. When the DCS monitoring system 62 detects that there is no oxygen in the gas storage chamber 401, it means that the oxygen-containing air retained in the gas storage chamber 401 and the oil cup 61 has been cleared. The DCS monitoring system 62 controls the high-voltage power supply 63 to generate electricity to pass high voltage electricity into the transformer insulating oil in the oil cup 61 through the electrode rod, thereby performing the detection operation.

[0114] Furthermore, when the transformer insulating oil boils, hot gas flows into the gas storage chamber 401, increasing the air pressure in the gas storage chamber 401, so that the gas can enter the air pressure chamber along the air inlet channel 403 to push the second sliding plate 307 downward, the third elastic member 314 is compressed, and the second support member is pushed by the second sliding plate 307 to further squeeze the airbag 315, so that the seal 303 and the annular pressure plate 302 are pressed and sealed more tightly and reliably, thereby further improving the sealing effect of the seal 303 and the annular pressure plate 302 on the oil cup 61, and reducing the probability of the sealing effect decreasing due to the increase in air pressure in the oil cup 61, so that the integrated detection device 100 can always obtain a stable and reliable sealing effect during the detection process of the transformer insulating oil, thereby effectively avoiding the situation where the transformer insulating oil burns when the integrated detection device 100 is performing the detection operation, so that the safety of the integrated detection device 100 during the detection operation is well guaranteed.
