Description

Technical Field

[0001] This invention relates to the technical field of auxiliary equipment for online chromatographic analysis systems of transformer oil, and more particularly to a device for collecting and storing separated gases from transformer oil. Background Technology

[0002] Transformer oil is currently one of the most important media for the normal operation of transformers, effectively isolating, cooling, and protecting the transformer's insulation system. However, as transformers age, the chemical and physical properties of the transformer oil change, leading to some indicators exceeding standards or becoming abnormal. These abnormalities can cause transformer failures and jeopardize normal operation. Therefore, timely monitoring of changes in the chemical indicators of transformer oil and conducting diagnostic assessments can effectively prevent transformer failures.

[0003] A transformer oil chromatography online analysis system is an instrument used to monitor the composition and concentration of gases and dissolved gases in transformer oil in real time. However, online transformer oil chromatography analysis requires an oil-gas separation process to separate the gases from the transformer oil for analysis. Regarding the aforementioned related technologies, the inventors believe that existing transformer oil chromatography online analysis systems require the storage of the separated gases before sampling and analysis.

[0004] However, most existing gas collection and storage devices use sealed tanks to store a single type of gas, which is not conducive to classifying and storing multiple gases according to actual needs. If multiple sealed tanks are used to store different gases, multiple sealed tanks need to be managed independently, resulting in high management costs. In addition, the inside of the sealed tanks is not easy to clean thoroughly, resulting in high maintenance costs. Summary of the Invention

[0068] This invention provides a transformer oil separation gas collection and storage device to solve the technical problem of high cost of existing gas collection and storage equipment.

[0069] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0072] Please see Figures 1 to 13 The present invention provides a transformer oil separation gas collection and storage device, comprising: a base plate 1, a water seal box group 3, a cleaning box 4, and multiple storage tanks 2;

[0073] The tray 1 includes a tray body 11 and multiple drainage seats 12 arranged in a circle;

[0074] The drainage seats 12 are evenly arranged on the upper end surface of the disc body 11, and the drainage seats 12 are fixedly connected to the disc body 11;

[0075] Storage tank 2 includes tank body 21 and gas cover bracket 22;

[0076] The lower ends of the tank bodies 21 of multiple storage tanks 2 are respectively sealed and detachably installed on the corresponding drainage seats 12, and the tank bodies 21 are fixedly connected to the corresponding drainage seats 12;

[0077] The gas cap bracket 22 is sealed and installed on the top of the tank body 21;

[0078] An air inlet pipe 23 is installed on the air cover bracket 22, and a control valve 233 is installed on the air inlet pipe 23;

[0079] The water seal tank assembly 3 includes a distribution pipe rack 31 and a water storage tank 32;

[0080] The shunt tube support 31 is fixedly installed at the center of the upper end face of the disc body 11;

[0081] The lower end of the diversion pipe rack 31 is connected to the lower end of the internal space formed by the combination of the diversion seat 12 and the tank body 21;

[0082] The water storage tank 32 is installed at the upper end of the diversion pipe frame 31;

[0083] The interior of the water storage tank 32 is sealed and fixedly connected to the upper end of the diversion pipe frame 31;

[0084] The cleaning box 4 is located below the disk body 11, and the cleaning box 4 is fixedly connected to the disk body 11.

[0085] It is understandable that when installing the storage tank 2, the lower end of the tank body 21 is sealed and connected to the diversion seat 12, and then the gas cover bracket 22 is sealed and installed on the upper end of the tank body 21. The tank body 21, the diversion seat 12 and the gas cover bracket 33 can be disassembled from each other, which facilitates better cleaning and maintenance of the interior later. The structure of the water seal box group 3 can ensure that the water storage shell 32 can be connected to the interior of each storage tank 2 through the diversion pipe bracket 31, and at the same time, it can make the overall structure layout of the device more compact. The air inlet pipe 23 is equipped with a corresponding control valve 233, which can control the opening and closing of the air inlet pipe 23, so as to flexibly select the water storage shell 32 to cooperate with different storage tanks 2, which is convenient for the classified storage of various gases. The cleaning box 4 is set below the base plate 1, which can facilitate the collection of wastewater when cleaning the storage tank 2, and facilitate better centralized cleaning. All the above technical features make the management cost and maintenance cost of the transformer oil separation gas collection and storage device provided by the present invention low.

[0086] It should be noted that the capacity of the water storage shell 32 is preferably greater than or equal to the total capacity of all tanks 21; the water storage shell 32 may be covered with a cover with an open bottom, which ensures that the water storage shell 32 is connected to the atmosphere while preventing the water in the water storage shell 32 from being mixed with volatile substances from the outside and contaminating the gas in the tank 21; a level gauge may be installed in each tank 21, and the gas storage in the tank 21 can be confirmed by the measurement value of the level gauge.

[0087] When gas storage is required, the gas storage operation can be carried out by using the inlet pipe 23 and control valve 233 in conjunction with the pump: First, select the appropriate storage tank 2 for gas storage operation according to actual needs. After selection, connect the inlet pipe 23 corresponding to the storage tank 2 to the gas pump and open the control valve 233 on the inlet pipe 23. After the gas enters the storage tank 2 from the inlet pipe 23, the liquid in the storage tank 2 is squeezed into the water storage tank 32 through the diversion pipe frame 31 to realize the gas storage operation. After storage is completed, close the control valve 233 on the inlet pipe 23. The water in the water seal tank group 3 keeps the space inside the tank 21 in a sealed state, ensuring the stable storage of gas in the storage tank 2.

[0088] When the gas inside the tank needs to be used, first open the control valve 233 to connect the inside of the tank 21 to the atmosphere. Due to the principle of communicating vessels, the water pressure generated by the high water level in the water tank 32 causes the liquid level inside the tank 21 to rise, causing the gas inside the tank 21 to be discharged from the air inlet pipe 23 of the storage tank 2. When it is necessary to store the gas generated by the oil-gas separation, connect the air inlet pipe 23 to the air outlet of the oil-gas separation device, open the control valve 233, and let the gas generated by the oil-gas separation device be input into the storage tank 2.

[0089] In a preferred embodiment, such as Figures 3 to 4 and Figures 7 to 9 As shown, a support frame 13 connected to the cleaning box 4 is provided on the lower end face of the disc body 11; the lower end of the support frame 13 is fixedly installed in the cleaning box 4, and the upper end of the support frame 13 is fixedly connected to the lower end face of the disc body 11. By providing the support frame 13 on the lower end face of the disc body 11, the disc body 11 can be supported and fixed in the cleaning box 4; furthermore, the support frame 13 and the lower end face of the disc body 11 can be rotatably connected, which facilitates the quick selection of the required storage tank or the switching to the next storage tank from multiple storage tanks 2 when using this device.

[0090] Furthermore, such as Figures 8 to 9 As shown, the drainage seat 12 includes a base 121 and an annular plate 122; the annular plate 122 is coaxially disposed on the upper end face of the base 121, and the annular plate 122 and the base 121 are integrally formed; the tank body 21 includes an outer tank shell 211, a top ring plate 212 and a bottom ring plate 213; the top ring plate 212 and the bottom ring plate 213 are respectively disposed on the upper and lower ends of the inner side of the outer tank shell 211, and the top ring plate 212 and the bottom ring plate 213 are integrally formed with the outer tank shell 211; the gas cover frame 22 includes a cover shell 221 and a bottom ring shell 222; the bottom ring shell 222 is disposed on the lower end face of the cover shell 221, and the bottom ring shell 222 and the cover shell 221 are integrally formed. The annular plate 122 on the drain seat 12 can cooperate with the bottom ring plate 213 on the inner side of the tank body 21, and the outer diameter of the annular plate 122 is preferably the same as the inner diameter of the bottom ring plate 213; the top ring plate 212 on the inner side of the tank body 21 can cooperate with the bottom ring shell 222 of the gas cover bracket 22, and the inner diameter of the top ring plate 212 is preferably the same as the outer diameter of the bottom ring shell 222; furthermore, in order to ensure a good sealing effect between the drain seat 12 and the tank body 21 and between the tank body 21 and the gas cover bracket 22, sealing rings can be provided between the annular plate 122 and the bottom ring plate 213 and between the bottom ring shell 222 and the top ring plate 212, respectively.

[0091] Furthermore, such as Figures 8 to 9As shown, the air inlet pipe 23 includes a horizontal pipe 231 and a vertical pipe 232; the horizontal pipe 231 is integrally formed and disposed on the side of the cover shell 221; the vertical pipe 232 is vertically installed on the top of the horizontal pipe 231. The horizontal pipe 231 extends the air outlet of the storage tank 2 outward, which facilitates the connection between the air inlet pipe 23 and the air pump; the air outlet of the vertical pipe 232 is located at its highest position, and the highest position of the vertical pipe 232 is preferably higher than or equal to the highest water level of the water tank 32, which can prevent the water level in the tank from overflowing from the air inlet pipe 23 due to excessive water level.

[0092] Furthermore, such as Figure 6 and Figures 8 to 11 As shown, a plurality of connecting screws 14 are evenly arranged along the circumferential direction on the upper end face of the disc body 11, and the connecting screws 14 are perpendicularly and fixedly connected to the disc body 11; a matching locking nut 141 is provided on the connecting screws 14; a connecting top plate 214 and a bent bottom plate 215 matching the connecting screws 14 are respectively provided on the upper and lower ends of the outer side of the outer shell 211; the connecting top plate 214 and the connecting bottom plate are integrally formed with the outer shell 211; the control valve 233 is installed on the transverse pipe 231; the lower end face of the transverse pipe 231 is symmetrically installed with the connecting top plate 214. The connecting rod 235 is vertically fixedly connected to the transverse tube 231; the two sides of the rod 235 are symmetrically provided with limiting slots 234; the rod 235 is detachably connected to the locking frame 24 installed on the limiting slots; the locking frame 24 includes a concave shell 241 adapted to the limiting slots 234 and an outer plate 242; the outer plate 242 is disposed on one side of the concave shell 241 and is integrally formed with the concave shell 241; a magnetic block 243 that attracts the side of the connecting top plate 214 is also provided on the inner side of the outer plate 242. The bent bottom plate 215 is fixed to the chassis 1 by screw 14 and locking nut 141, which allows the lower end of the tank 21 to better fit and connect with the drain seat 12, ensuring the sealing between the tank 21 and the drain seat 12; the connecting top plate 214 is fixedly connected to the gas cap bracket 22 by insert rod 235 and locking bracket 24, which allows the upper end of the tank 21 to better fit and connect with the gas cap bracket 22, ensuring the sealing between the tank 21 and the gas cap bracket 22; during installation, first insert the two insert rods 235 into the connecting top plate 21. The corresponding holes on the 4 allow the two insert rods 235 to restrict the relative positions between the tank body 21 and the gas cover bracket 22. Then, the concave shell 241 is inserted into the limiting slots 234 on both sides of the insert rod 235. This prevents the insert rod 235 from sliding out of the hole in the connecting top plate 214, ensuring the stability of the installation of the tank body 21 and the gas cover bracket 22. At the same time, the magnetic block 243 on the outer plate 242 causes the locking frame 24 to be attracted to the side of the connecting top plate 214, ensuring the stable limiting effect of the locking frame 24 on the insert rod 235.

[0093] Furthermore, the diversion pipe rack 31 includes a central pipe 311 and external pipes 312; the external pipes 312 are evenly arranged outside the lower end of the central pipe 311, and the external pipes 312 are sealed and fixedly connected to the central pipe 311; several auxiliary support rods 321 are fixedly installed at the lower end of the water storage shell 32, and the auxiliary support rods 321 are detachably connected to the chassis 1. The central pipe 311 is vertically fixed at the center of the upper end face of the plate body 11, and each external pipe 312 can connect the central pipe 311 to different diversion seats 12; furthermore, each external pipe 312 is equipped with an individual control valve, which can be selected to be opened as needed.

[0094] In a preferred embodiment, such as Figures 12 to 13 As shown, a mixing tank 5 can be installed in the cleaning tank 4; a stirring motor 6 is fixedly installed on the upper end of the mixing tank 5; a stirring rod 61 is installed on the lower end of the stirring motor 6; a flushing pump 7 is installed in the mixing tank 5; a water outlet pipe 71 is installed on the output port of the flushing pump 7; and a hose 72 is sealed to the outlet of the water outlet pipe 71. When the device needs to be cleaned, a cleaning solution can be prepared inside the mixing tank 5. The cleaning agent and the aqueous solution are mixed in the mixing tank 5, and then the cleaning solution is used to flush the device through the water outlet pipe 71 and the hose 72 installed on the flushing pump 7.
