Description

Technical Field

[0001] This utility model relates to the field of power transformer technology, and in particular to a coil arrangement structure for a high-resistance on-load power transformer. Background Technology

[0002] High impedance on-load power transformers are power transformers with specific impedance characteristics and voltage regulation functions. Their core lies in achieving high short-circuit impedance through structural design and being able to regulate voltage under load. High impedance on-load power transformers are mainly used in high-voltage transmission systems, large industrial loads, urban power grid transformation, and new energy grid connection, etc., where it is necessary to limit short-circuit current and stabilize voltage.

[0003] Existing technology, with publication number CN214753345U, discloses a coil arrangement structure for a high-resistance on-load power transformer, including a lower support frame. A strip support plate is fixedly installed on the outer surface of the lower support frame, and one side of the top of the strip support plate is fixedly connected to the outer surface of the upper support frame. This invention, through the setting of the strip support plate and lifting limit plates, allows workers to raise and lower each lifting limit plate along a guide slide rod, and then wind the mixed coils between each lifting limit plate. After adjustment, the mixed coils are separated from the low-voltage line group due to the arc-shaped isolation plate. This not only avoids the confusion caused by entanglement, making separation difficult for workers, but also allows workers to flexibly adjust the mixed coils according to their type and the spacing between them, greatly improving the practicality of the device.

[0004] When workers need to arrange coils, they install the coils on the arrangement structure so that the arrangement structure can arrange the coils. However, the existing arrangement structure cannot dissipate heat during use because the distance between the support structure and the winding is too small, which causes the transformer to overheat and thus shortens the service life of the transformer. Utility Model Content

[0005] The purpose of this invention is to solve the problem of shortened service life of transformers in the prior art, and to propose a coil arrangement structure for a high-resistance on-load power transformer.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a coil arrangement structure for a high-resistance on-load power transformer, comprising a first support plate, a second support plate mounted on the lower surface of the first support plate, a wire loop installed between the first and second support plates, a connecting strip installed between the first and second support plates, a cooling device provided on the surface of the first support plate, the cooling device comprising a gas-gathering sleeve, the gas-gathering sleeve being fitted onto the surfaces of the first rotating plate and the second support plate, an air jet hole being provided on the inner side of the gas-gathering sleeve, and air jet holes being provided on both sides of the gas-gathering sleeve. The device includes an air chamber, inside which a drive motor is fixedly connected. A fan blade is fixedly connected to the drive end of the drive motor and is located inside the air chamber. A cooling chamber is fixedly connected to the lower surface of the air chamber, and a duct is fixedly connected to the lower surface of the cooling chamber. The duct is connected to the interior of an air-gathering sleeve. A cooling assembly, including a cooling chip, is installed inside the cooling chamber and is fixedly connected to the interior of the cooling chamber. The cooling chip is located above the duct and can cooperate with the cooling chamber to support the cooling chip in cooling the air.

[0007] Preferably, the surface of the connecting strip is provided with a fixing device, the fixing device including a socket, the socket being opened on the surface of the connecting strip, the socket being located on one side of the gas-gathering sleeve, the socket being able to cooperate with the connecting strip to achieve the purpose of storing the positioning block.

[0008] Preferably, the gas-gathering sleeve has an internal threaded connection with a positioning block, which is inserted into the interior of the insertion hole. The positioning block can cooperate with the gas-gathering sleeve and the insertion hole to restrict the sliding of the gas-gathering sleeve.

[0009] Preferably, the surfaces of the two sets of connecting strips are provided with placement grooves, which are located inside the gas-gathering sleeve. The placement grooves can cooperate with the connecting strips to achieve the purpose of storing the stabilizing block.

[0010] Preferably, a stabilizing block is fixedly connected to the surface of the gas-gathering sleeve. The stabilizing block is placed on the surface of the placement groove, and the stabilizing block can cooperate with the gas-gathering sleeve to achieve the purpose of fixing the stabilizing block.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting up a cooling device, when the operator needs to cool the transformer, the operator activates the cooling chip and drive motor. The drive motor drives the fan blades, which rotate and push air into the cooling chamber. The cooling chip in the cooling chamber cools the air, and the cold air enters the gas-gathering sleeve through the air guide pipe. Subsequently, the internal space of the gas-gathering sleeve guides the cold air to be ejected from the jet nozzle. The cold air mixes with the hot air inside the gas-gathering sleeve. As the cold air is continuously discharged, the overall temperature of the air decreases, and the cold air cools the coil. By setting up a cooling device, the operator can effectively and conveniently cool the transformer, avoid overheating of the transformer, and thus improve the service life of the transformer.

[0012] In this invention, by setting a fixing device, when the worker needs to fix the gas-gathering sleeve, the worker puts the gas-gathering sleeve on the coil arrangement structure, and the gas-gathering sleeve drives the stabilizing block to be placed in the placement groove. When the gas-gathering sleeve is placed in the designated position, the worker rotates the positioning block, and the positioning block extends and inserts into the insertion hole. By setting a fixing device, it is possible to effectively and conveniently fix the gas-gathering sleeve, avoiding the time-consuming situation when the worker installs the cooling device, thereby improving the worker's work efficiency.

[0016] The specific setup and function of the cooling device 3 and the fixing device 4 will be explained below.

[0017] In this embodiment: the cooling device 3 includes a gas-gathering sleeve 32, which is sleeved on the surface of the first rotating plate and the second support plate 2. The gas-gathering sleeve 32 has an air jet hole 31 on its inner side. Air chambers 36 are provided on both sides of the gas-gathering sleeve 32. A drive motor 33 is fixedly connected inside the air chamber 36. A fan blade 38 is fixedly connected to the drive end of the drive motor 33. The fan blade 38 is located inside the air chamber 36. A cooling chamber 35 is fixedly connected to the lower surface of the air chamber 36. A duct 37 is fixedly connected to the lower surface of the cooling chamber 35. The duct 37 is connected to the inside of the gas-gathering sleeve 32. A cooling component is provided inside the cooling chamber 35.

[0018] Specifically, the cooling component includes a cooling chip 34, which is fixedly connected to the interior of the cooling cavity 35. The cooling chip 34 is located above the air duct 37 and can cooperate with the cooling cavity 35 to support the cooling chip 34 in cooling the air.

[0019] Specifically, a fixing device 4 is provided on the surface of the connecting strip. The fixing device 4 includes a socket 42, which is opened on the surface of the connecting strip and is located on one side of the gas-gathering sleeve 32.

[0020] In this embodiment, the insertion hole 42 can cooperate with the connecting strip to achieve the purpose of storing the positioning block 41.

[0021] In this embodiment: the internal thread of the gas-gathering sleeve 32 is connected to a positioning block 41, which is inserted into the interior of the insertion hole 42. The positioning block 41 can cooperate with the gas-gathering sleeve 32 and the insertion hole 42 to restrict the sliding of the gas-gathering sleeve 32.

[0022] Specifically, the surfaces of the two sets of connecting strips are provided with placement grooves 43, which are located inside the gas-gathering sleeve 32.

[0023] In this embodiment: the placement slot 43 can cooperate with the connecting strip to achieve the purpose of storing the stabilizing block 44.

[0024] Specifically, a stabilizing block 44 is fixedly connected to the surface of the gas-gathering sleeve 32, and the stabilizing block 44 is placed on the surface of the placement groove 43.

[0025] In this embodiment, the stabilizing block 44 can be used in conjunction with the gas-gathering sleeve 32 to fix the stabilizing block 44.

[0026] Working principle: By setting up the cooling device 3, when the operator needs to cool the transformer, the operator activates the cooling chip 34 and the drive motor 33. The drive motor 33 drives the fan blades 38, which rotate and push air into the cooling chamber 35. The cooling chip 34 in the cooling chamber 35 cools the air. The cold air enters the gas-gathering sleeve 32 through the air guide pipe 37. Subsequently, the internal space of the gas-gathering sleeve 32 guides the cold air to be ejected from the jet hole 31. The cold air mixes with the hot air inside the gas-gathering sleeve 32. As the cold air continues to be discharged, the overall temperature of the air decreases, and the cold air cools the coil 5. By setting up the cooling device 3, the operation can be effectively and conveniently carried out. The cooling device 3 is used to cool the transformer, preventing overheating and extending its service life. Additionally, by installing the fixing device 4, when the worker needs to fix the gas-gathering sleeve 32, the worker places the sleeve 32 onto the coil 5 arrangement structure. The sleeve 32 then moves the stabilizing block 44 into the placement slot 43. When the sleeve 32 is in the designated position, the worker rotates the positioning block 41, which extends and inserts into the insertion hole 42. The fixing device 4 effectively facilitates the worker's fixation of the gas-gathering sleeve 32, avoiding time-consuming installation of the cooling device 3 and improving work efficiency.
