Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a transformer vacuum oil filling liquid level detection device. Background Art

[0002] Before an oil-immersed transformer is used, transformer oil is usually added to it by vacuum oil filling, so that the inside of the oil-immersed transformer is in a vacuum-sealed state, and the transformer oil is used to achieve insulation, heat dissipation and lubrication. Therefore, the use of transformer oil in transformers is indispensable, and it comprehensively improves the performance and safety of the transformer.

[0003] At present, when replacing the transformer oil of the existing oil-immersed transformer, the oil drain port of the transformer is usually opened manually to allow the transformer oil to flow out naturally and drip into the container located below the transformer. Since the existing carrying container is not yet equipped with cooling equipment, the transformer oil in a working state is discharged from the transformer, and the temperature of the transformer oil is relatively high. The high temperature causes the staff to be unable to recycle and process the transformer oil in time, thereby wasting a lot of time costs of the staff, thereby reducing the work efficiency of recycling and processing of deteriorated transformer oil, thereby increasing the workload of the staff. In addition, during the process of filling the transformer oil, when the transformer oil is filled to the required oil level of the oil-immersed transformer, the staff needs to carefully observe the oil level gauge to understand the oil level inside the transformer, and the valve of the oil filling pipe cannot be automatically closed, so the transformer may be filled with too much oil, resulting in an excessive volume of transformer oil and interference with the normal operation of the transformer, which will not only affect the life of the transformer, but also may cause damage to the equipment.

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0038] Embodiment 1

[0039] Please refer to Figures 1 to 8As shown, in order to solve the problems mentioned in the technical solution, an embodiment of the present application provides a transformer vacuum oil filling liquid level detection device, including a transformer body 1, and an oil pillow 101 is fixedly connected to one side of the top of the transformer body 1, which is used to buffer transformer oil for the transformer body 1 and increase its range of loading transformer oil. The transformer body 1 is connected to the oil pillow 101 through an explosion-proof pipe 102. An oil level gauge 103 is fixedly connected to the outer wall of one side of the oil pillow 101. The bottom of the oil level gauge 103 is connected to the oil pillow 101. An indicating piston 104 is slidably connected in the oil level gauge 103, which is used to reflect the oil level in the transformer body 1. An oil drain valve 105 is fixedly connected to the outer wall of the bottom of the transformer body 1 through an oil outlet. An oil filling adjustment mechanism is provided on the oil level gauge 103, and the oil filling adjustment mechanism includes a magnet 2, which is fixedly connected to the top of the indicating piston 104. An annular magnet 201 is slidably connected to the outer surface of the oil level gauge 103. The magnetism of the annular magnet 201 is opposite to that of the magnet 2, and the magnetic force of the annular magnet 201 is greater than that of the magnet 2, thereby preventing the annular magnet 201 from being separated from the magnet 2 due to insufficient adsorption force when the indicating piston 104 moves up and down. The outer surface of the annular magnet 201 is rotatably connected to an extrusion block 202, and a torsion spring 203 is fixedly connected between the extrusion block 202 and the annular magnet 201. The torsion spring 203 is sleeved on the rotating shaft of the extrusion block 202. The upper and lower ends of the oil level gauge 103 are fixedly connected to touch switches 204, and the number of touch switches 204 is two, and the two touch switches 204 are both located on the movement trajectory of the extrusion block 202, wherein the vertical height of the annular magnet 201 is greater than the width of the extrusion block 202, so that when the extrusion block 202 is in a horizontal state, it cannot contact the touch switch 204 located at the bottom of the oil level gauge 103, and the oil pillow 101 is fixedly connected to a fixed limit plate 205 on one side of the oil level gauge 103, which is used to limit the movement range of the extrusion block 202 in the upper area of ​​the oil level gauge 103.

[0040] The oil pillow 101 is provided with a reset assembly at one side of the oil level gauge 103. The reset assembly includes a slide rail 206, which is fixedly connected to the outer wall of the oil pillow 101 at one side of the oil level gauge 103. The inner wall of the slide rail 206 is symmetrically provided with a limit groove 2061, and a movable limit plate 2062 is slidably connected inside the limit groove 2061, wherein the movable limit plate 2062 and the fixed limit plate 205 are both fitted with the extrusion block 202, and the limit groove 2061 is composed of a vertical groove and an inclined groove, and the bottom of the vertical groove is connected to the bottom of the inclined groove, so that the movable limit plate 2062 cannot automatically move away from the oil level gauge 103 when being squeezed by the extrusion block 202. A slide bar 2063 is slidably connected between the inner walls of the slide rail 206, and the slide bar 2063 can slide vertically up and down along the inner wall of the slide rail 206, which is used to facilitate workers to manually adjust the position of the movable limit plate 2062. The movable limit plate 2062 is slidably connected to the outer surface of the slide bar 2063. A telescopic spring 2064 is fixedly connected between the side of the movable limit plate 2062 away from the oil level gauge 103 and the opposite surface of the slide rail 206. The telescopic spring 2064 is sleeved on the outer surface of the slide bar 2063. The top outer wall of the transformer body 1 is fixedly connected to an electric push rod 207. The output rod of the electric push rod 207 is fixedly connected to a rack 208. The rack 208 is slidably connected to the top outer wall of the transformer body 1. A ball valve 209 is installed at the oil inlet on the top of the transformer body 1. The valve handle of the ball valve 209 is fixedly connected to a gear 210, and the gear teeth on the gear 210 are one-fourth of the total number, which is used to limit the rotation angle of the valve handle. The gear 210 is meshed with the rack 208. The two touch switches 204 are electrically connected to the electric push rod 207 and their extension and retraction are controlled by the controller. The touch switch 204 located at the top of the oil level gauge 103 is controlled by the controller to extend the electric push rod 207 at a uniform speed, and the touch switch 204 located at the bottom of the oil level gauge 103 is controlled by the controller to be evenly retracted.

[0041] Working process: Initial state before use: transformer oil is not added to the transformer body 1, and the indicating piston 104 in the oil level gauge 103 is located at its lower part. Therefore, the magnet 2 on the indicating piston 104 drives the annular magnet 201 to be located at the lower part through the adsorption force, and the extrusion block 202 on the annular magnet 201 is in a horizontal state due to the torque force of the torsion spring 203. At the same time, the staff manually pulls the movable limit plate 2062, so that the slide bar 2063 on the movable limit plate 2062 moves up along the inner wall of the slide rail 206, causing the movable limit plate 2062 to disengage from the limit groove 2061, and then the staff manually pulls the movable limit plate 2062 to move along the surface of the slide bar 2063 in the direction away from the oil level gauge 103. The movable limit plate 2062 continuously squeezes the telescopic spring 2064 to contract, and then the extrusion block 202 in a horizontal state slides down to the lower part of the oil level gauge 103. At this time, the staff releases the movable limit plate 2062, and under the elastic action of the telescopic spring 2064, the movable limit plate 2062 is fitted with one end of the extrusion block 202 in a horizontal state, so that the movable limit plate 2062 and the fixed limit plate 205 are not located on the same vertical plane. At this time, the extrusion block 202 in a horizontal state does not contact the touch switch 204 located at the lower part of the oil level gauge 103 due to the mutual interference between the annular magnet 201 and the bottom end of the oil level gauge 103, so that the output rod of the electric push rod 207 is in a non-extended state, and the ball valve 209 is in an open state.

[0042] During operation: During vacuum oil filling, the staff first connects the output end of the external vacuum unit to the oil drain valve 105 at the oil outlet through bolts, then connects the oil pipe of the oil filling tank to the top of the ball valve 209 through bolts, and closes the oil outlet valve of the oil filling tank. Then the external vacuum unit starts to work in vacuum until the vacuum degree inside the transformer body 1 reaches the set value. Then, the oil drain valve 105 is closed first, the external vacuum unit is disassembled, and then the oil outlet valve of the oil filling tank is opened. Then, the transformer body 1 is filled with vacuum. Under the action of the high negative pressure inside the body 1, the transformer oil in the oil filling tank gradually flows into the inside. In this process, as the amount of oil inside the transformer body 1 continues to increase, the indicating piston 104 in the oil level gauge 103 moves upward along the inside of the oil level gauge 103, and the indicating piston 104 drives the magnet 2 to move upward, and drives the annular magnet 201 to move upward along the outer surface of the oil level gauge 103 through the adsorption force. When the extrusion block 202 in a horizontal state contacts the fixed limiting plate 205, the bottom of the fixed limiting plate 205 contacts the extrusion block 202. The extrusion block 202 is rotated along the surface of the magnet 2 through the rotating shaft thereon, so that it can no longer move upward horizontally. Then, the extrusion block 202 rotates along the surface of the magnet 2 through the rotating shaft thereon, so that it rotates from the horizontal state to the vertical state, and causes the extrusion block 202 to rotate and the torsion spring 203 to gradually shrink. Subsequently, the extrusion block 202 moves vertically upward in contact with the surface of the fixed limit plate 205. When the extrusion block 202 squeezes the touch switch 204, the electric push rod 207 is started and extended at a uniform speed through the controller. The output rod of the electric push rod 207 pushes the rack 208 along the variable speed at a uniform speed. The top of the transformer body 1 slides, and the rack 208 drives the gear 210 meshing with it to rotate ninety degrees, and then the gear 210 drives the valve handle of the ball valve 209 to rotate ninety degrees, so that the ball valve 209 is closed, thereby realizing the function of automatically closing the valve when the oil is full and stopping filling, avoiding the normal operation of the transformer body 1 due to excessive oil filling resulting in excessive transformer oil volume, and also avoiding the situation that when there is too much oil inside the transformer body 1, the oil level rises and causes oil overflow due to the influence of high temperature environment or high load for a long time.

[0043] When the extrusion block 202 moves to the upper part of the oil level gauge 103 and is separated from the movable limit plate 2062, the telescopic spring 2064 pushes the movable limit plate 2062 to move toward the oil level gauge 103 through its elastic action, so that the movable limit plate 2062 and the fixed limit plate 205 are located on the same vertical plane. When the amount of oil inside the transformer body 1 decreases, the oil level inside the oil level gauge 103 also decreases, causing the indicating piston 104 to move downward, and the extrusion block 202 is driven to move downward by the adsorption force between the magnet 2 and the annular magnet 201 until the extrusion block 202 squeezes the oil level gauge 103. The touch switch 204 at the bottom of the level meter 103 controls the electric push rod 207 to start and retract at a uniform speed through the controller. The output rod of the electric push rod 207 pulls the rack 208 to slide along the top of the transformer body 1 at a uniform speed. The rack 208 drives the gear 210 meshing with it to rotate ninety degrees in the opposite direction, so that the ball valve 209 opens, thereby continuing to add transformer oil to the inside of the transformer body 1, thereby ensuring that the oil level inside the transformer body 1 is always within the normal range, which can not only extend the service life of the transformer body 1, but also effectively protect the equipment inside the transformer body 1.

[0044] Embodiment 2

[0045] Please refer to Figures 1 to 3 , Fig. 9 as well as Fig.10 As shown, a waste oil collection mechanism is provided at the bottom of the transformer body 1, and the waste oil collection mechanism includes a carrying box 3, which is slidably connected to the bottom of the transformer body 1, and the carrying box 3 is located directly above the water tank 4, an oil pump 301 is fixedly connected to the outer wall of one side of the carrying box 3, an oil inlet of the oil pump 301 is fixedly connected to an oil suction pipe 302, an end of the oil suction pipe 302 away from the oil pump 301 is fixedly connected to a female end joint 303, an oil discharge valve 105 is fixedly connected to a male end joint 304, the female end joint 303 and the male end joint 304 are engaged with each other, the oil outlet of the oil pump 301 is connected to the carrying box 3 through the oil discharge pipe 305, buckles 306 are symmetrically fixedly connected to the outer walls of both sides of the carrying box 3, and slots 307 are symmetrically fixedly connected to both sides of the bottom of the transformer body 1, the buckles 306 and the slots 307 are engaged with each other, which are used for quick disassembly and assembly of the carrying box 3.

[0046] Working process: When the transformer oil in the transformer body 1 needs to be replaced due to oil quality deterioration, the staff first aligns the female end connector 303 on the oil suction pipe 302 with the male end connector 304 on the oil drain valve 105 and inserts the female end connector 303 into the outer surface of the male end connector 304, so that the oil drain valve 105 is tightly connected to the oil suction pipe 302. Then the staff manually opens the oil drain valve 105 to make the inside of the transformer body 1 and the oil suction pipe 302 communicate with each other. Then the staff starts the oil pump 301 to start working, and the transformer oil in the transformer body 1 is sucked into it by the suction force generated by the oil pump 301. Then the transformer oil entering the oil pump 301 flows out from the inside of the oil drain pipe 305. The oil is discharged from the outside of the oil pump 301 and flows into the inside of the carrying box 3 from the inside of the oil discharge pipe 305. At the same time, the indicating piston 104 located in the oil level gauge 103 slides down along the inside of the oil level gauge 103 as the oil level drops, and drives the squeezing block 202 on the annular magnet 201 to move down through the magnet 2, so that the squeezing block 202 gradually approaches the touch switch 204 located at the lower part of the oil level gauge 103. When the squeezing block 202 is separated from the fixed limit plate 205, the staff manually pulls up the movable limit plate 2062 to separate it from the limit groove 2061, and then the staff pulls the movable limit plate 2062 to move along the inside of the slide rail 206 to gradually move it away from the oil level gauge 103. At this time, the movable limit plate 2062 is separated from the fixed limit plate 205. The detached extrusion block 202 loses the limiting effect of the movable limit plate 2062, so that the torsion spring 203 thereon gradually returns to its original state, and drives the extrusion block 202 to rotate from a vertical horizontal state to a horizontal horizontal state through the torque force, so that when the transformer oil in the transformer body 1 is drained, the extrusion block 202 cannot contact the touch switch 204 located at the lower part of the oil level gauge 103, so that the ball valve 209 cannot be opened, thereby preventing the new oil in the oil filling tank from entering the transformer body 1 during the oil draining process. After the oil is drained, the staff can close the oil drain valve 105, and then open the ball valve 209, and use the negative pressure in the transformer body 1 to suck the new transformer oil in the oil filling tank into the transformer body 1. Inside, the staff can press the buckle 306 to disengage the surface of the buckle 306 from the inside of the slot 307, and then the staff pushes the carrying box 3 to slide along the bottom of the transformer body 1, so that the buckle 306 gradually moves away from the slot 307, thereby quickly replacing the transformer oil inside the transformer body 1, thereby simplifying the operating process of changing the oil of the transformer body 1, thereby reducing the work intensity of the staff, and at the same time, the deteriorated transformer oil can be collected in a centralized manner, which can effectively reduce the risk of environmental pollution caused by harmful substances in the deteriorated transformer oil, thereby effectively reducing the waste of deteriorated transformer oil and improving the utilization rate of transformer oil, thereby realizing the effective recovery and reuse of transformer oil.

[0047] Embodiment 3

[0048] Please refer to Figure 1 , Figure 2 , Fig.10 as well as Fig.11 As shown, a cooling mechanism is provided at the bottom of the transformer body 1, and the cooling mechanism includes a water tank 4, which is slidably connected to the bottom of the transformer body 1, and a cooling plate is built into the water tank 4, which is used to effectively control the temperature of the cooling water inside the water tank 4, so as to ensure that the temperature of the transformer oil and the transformer body 1 can be effectively reduced. A water pump 401 is fixedly connected to one side of the top of the water tank 4, and a heat pipe 2 403 is fixedly connected to the outer wall of the bottom of the transformer body 1, and a heat pipe 1 402 is fixedly connected to the bottom end of the heat pipe 2 403, and both ends of the heat pipe 2 403 are connected to the heat pipe 1 402, wherein the heat pipe 1 402 is located at the inner bottom wall of the bearing box 3, and the heat pipe 1 402 and the heat pipe 2 403 are both in a winding shape as a whole, which is used to increase the moving path of the cooling water inside it, thereby increasing the time for the cooling water to stay in the bearing box 3 and at the bottom of the transformer body 1. The heat transfer pipe 1 402 is connected to the water outlet of the water pump 401 via the water outlet pipe 404, and the water tank 4 is connected to the water inlet of the water pump 401 via the water inlet pipe 405, so that the cooling water in the water tank 4 can be circulated and transported to the heat transfer pipe 1 402 through the water pump 401.

[0049] Working process: When the deteriorated transformer oil inside the transformer body 1 is completely drained into the bearing box 3, the staff first starts the water pump 401 to start working, and draws cooling water from the water tank 4 through the water inlet pipe 405, so that the cooling water first flows into the water pump 401, and then the cooling water is transported to the heat pipe 1 402 through the water outlet pipe 404. The cooling water flows at a uniform speed along the winding heat pipe 1 402. In this process, the transformer oil with a higher temperature transfers heat to the surface of the heat pipe 1 402, and then the heat pipe 1 402 transfers heat to the cooling water inside it, and continuously absorbs heat through the cooling water, and then the heated cooling water flows back to the water tank 4 from the heat pipe 1 402. The heated cooling water is cooled by the built-in refrigeration sheet of the water tank 4, and then the cooled cooling water can be circulated to the heat pipe 402 to continuously absorb the heat of the transformer oil, so as to achieve rapid cooling of the discharged transformer oil, thereby effectively reducing the temperature of the transformer oil, making it easier for the staff to carry out subsequent transformer oil treatment work more quickly, and effectively saving the time cost of recycling the transformer oil, so that the staff does not need to wait for a long time for the transformer oil to cool down, and can quickly filter and purify the transformer oil, thereby improving the work efficiency of the recovery and treatment of the deteriorated transformer oil, thereby reducing the workload of the staff.

[0050] When the transformer oil in the transformer body 1 does not need to be replaced, the water pump 401 in working state can also extract cooling water from the inside of the water tank 4 and make it flow from the inside of the heat pipe 1 402 into the inside of the heat pipe 2 403 connected thereto. Similarly, the heat pipe 2 403 absorbs the heat from the outer wall of the bottom of the transformer body 1 and transfers the heat to the cooling water in the heat pipe 2 403, which then flows back to the inside of the water tank 4 and cools the cooling water through its built-in refrigeration plate, thereby also cooling the transformer body 1 in working state, which can not only further dissipate heat and cool the transformer body 1, thereby improving the heat dissipation efficiency and effect of the transformer body 1, but also extend the service life of the transformer body 1.
