Description

Technical Field

[0001] This application relates to the field of dry-type transformer technology, and more specifically to an adjustable support for a dry-type transformer. Background Technology

[0002] A dry-type transformer is a type of transformer whose core and windings are not immersed in insulating oil, and it is widely used in various applications.

[0003] There is a dry-type transformer, such as Figure 1 As shown, the transformer includes a dry-type transformer body 90, an outer casing 91, two support bases 92, and an external busbar 93. The dry-type transformer body 90, the support bases 92, and the external busbar 93 are all located inside the outer casing 91. The two bottom feet of the dry-type transformer body 90 are respectively placed on the two support bases 92. The copper busbars on the dry-type transformer body 90 are all connected to the external busbar 93. However, current industry standards require the height of the external busbar 93 to be 2.2 meters, while the distance between the highest point of the dry-type transformer body 90 and the external busbar 93 is still relatively large. The current method is to extend the height of the power strip by a predetermined amount, which results in a large number of power strips being used. Since the power strip is made of copper, the cost of use is high.

[0004] Therefore, there is a need for an adjustable support base for dry-type transformers that can be height-adjusted, which helps reduce the amount of power strips used and has lower operating costs. Summary of the Invention

[0005] The main objective of this application is to provide an adjustable support base for a dry-type transformer, located at the bottom of the dry-type transformer body. The dry-type transformer body has two feet, and the adjustable support base includes two support base assemblies, each located below the two feet. Each support base assembly includes a lifting seat and a fixed seat. The lifting seat is located above the fixed seat and is raised and lowered on the fixed seat in the height direction. The lifting seat is located below the corresponding foot and supports the foot. By making the height of the lifting seat adjustable, when the distance between the dry-type transformer plug and the external busbar is a predetermined distance, the lifting seat can be moved upward by a predetermined distance to connect the dry-type transformer plug and the external busbar. Both the lifting seat and the fixed seat are made of cast iron. Compared with the prior art where the height of the lifting seat is fixed and the plug extension length is usually extended, which results in higher costs due to the copper material of the plug, this application has the advantages of adjustable support base height, reduced plug usage, and lower operating costs.

[0006] Another objective of this application is to provide an adjustable support for a dry-type transformer, wherein each support assembly further includes two sliding members, both of which are located between the lifting seat and the fixed seat, and the sliding members are slidably disposed on the fixed seat. Each sliding member has a first inclined surface, and the bottom of the lifting seat has two second inclined surfaces. The first inclined surface of each sliding member is in contact with the corresponding second inclined surface on the lifting seat. When the two sliding members move towards or away from each other, the lifting seat moves upward or downward to achieve the lifting seat being raised and lowered on the fixed seat.

[0007] Another objective of this application is to provide an adjustable support base for a dry-type transformer, wherein the adjustable support base further includes a dual-head motor and two rotating shafts. The dual-head motor is located between two support base assemblies, and the output shafts at both ends of the dual-head motor are detachably connected to the two rotating shafts respectively. Each rotating shaft is helically connected to two sliding members on the corresponding support base assembly, and each rotating shaft has a first helical part and a second helical part. The first helical part and the second helical part rotate in opposite directions, and the first helical part and the second helical part are helically connected to the two sliding members respectively, so as to realize that the two sliding members can move in opposite directions.

[0008] To achieve at least one of the above-mentioned objectives, this application provides an adjustable support base for a dry-type transformer, disposed at the bottom of the dry-type transformer body, wherein the dry-type transformer body has two feet, and wherein the adjustable support base for the dry-type transformer includes:

[0009] Two support base assemblies are respectively located below the two base feet. Each support base assembly includes a lifting base and a fixed base. The lifting base is located above the fixed base and is raised and lowered on the fixed base in the height direction of the fixed base. The lifting base is located below the corresponding base foot and supports the base foot.

[0010] In one or more embodiments of this application, each of the support base assemblies further includes two sliding members, both of which are located between the lifting base and the fixed base, and the sliding members are slidably disposed on the fixed base. Each sliding member has a first inclined surface, and the bottom of the lifting base has two second inclined surfaces. The first inclined surface of each sliding member is in contact with the corresponding second inclined surface on the lifting base. When the two sliding members move towards or away from each other, the lifting base moves upward or downward.

[0011] In one or more embodiments of this application, the adjustable support base of the dry-type transformer further includes a dual-head motor and two rotating shafts. The dual-head motor is located between the two support base assemblies. The output shafts at both ends of the dual-head motor are detachably connected to the two rotating shafts respectively. Each rotating shaft is helically connected to two sliding members on the corresponding support base assembly. Each rotating shaft has a first helical part and a second helical part. The first helical part and the second helical part rotate in opposite directions, and the first helical part and the second helical part are helically connected to the two sliding members respectively.

[0012] In one or more embodiments of this application, each of the fixed bases has a sliding groove, and both sliding members are slidably disposed in the sliding groove.

[0013] In one or more embodiments of this application, each of the support base assemblies further includes a plurality of telescopic components, the two ends of which are fixedly connected to the lifting base and the fixed base, respectively.

[0014] In one or more embodiments of this application, each of the telescopic components includes a rod, a sleeve, and a fastener. One end of the rod is raised and lowered within the sleeve. The end of the rod away from the sleeve is connected to the lifting seat. The end of the sleeve away from the rod is connected to the fixed seat.

It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0025] Indicative adjustable support for dry-type transformer, for reference. Figures 2 to 3According to a preferred embodiment of the present invention, an adjustable support base for a dry-type transformer is disposed at the bottom of the dry-type transformer body 10, wherein the dry-type transformer body 10 has two feet 101.

[0026] Furthermore, the adjustable support base of the dry-type transformer includes two support base assemblies 20, which are respectively located below the two base feet 101. Each support base assembly 20 includes a lifting base 201 and a fixed base 202. The lifting base 201 is located above the fixed base 202, and the lifting base 201 is raised and lowered on the fixed base 202 in the height direction. The lifting base 201 is located below the corresponding base foot 101 and supports the base foot 101.

[0027] It should be noted that both the lifting base 201 and the fixed base 202 are made of cast iron, which is less expensive than the copper used in power strips. Furthermore, by allowing the lifting base 201 to be raised and lowered on the fixed base 202, during installation, the lifting base 201 can be moved upwards a predetermined distance, causing the dry-type transformer body 10 to move upwards a predetermined distance and closer to the external power strip located at a height of 2.2 meters. This reduces the amount of copper busbars protruding from the dry-type transformer body 10. Compared to the fixed height of the support assembly 20 in the prior art, this embodiment allows for adjustable height of the support assembly, thus achieving advantages such as adjustable support height, reduced power strip usage, and lower operating costs.

[0028] Furthermore, to enable the lifting seat 201 to be lifted and lowered on the fixed seat 202, each support assembly 20 further includes two sliding members 203. Both sliding members 203 are located between the lifting seat 201 and the fixed seat 202, and the sliding members 203 are slidably disposed on the fixed seat 202. Each sliding member 203 has a first inclined surface 2031, and the bottom of the lifting seat 201 has two second inclined surfaces 2011. The first inclined surface 2031 of each sliding member 203 is in contact with the corresponding second inclined surface 2011 on the lifting seat 201. When the two sliding members 203 move towards or away from each other, the lifting seat 201 moves upward or downward.

[0029] It should be noted that when the two sliding members 203 move towards each other, the two sliding members 203 simultaneously apply an upward force to the lifting seat 201 from both sides, causing the lifting seat 201 to move upward and driving the dry-type transformer body 10 to move upward; when the two sliding members 203 move away from each other, the lifting seat 201 moves downward a predetermined distance along the first inclined surface 2031 and drives the dry-type transformer body 10 to move downward.

[0030] Furthermore, to enable the sliding members 203 to move in opposite directions, the adjustable support base of the dry-type transformer also includes a dual-head motor 30 and two rotating shafts 40. The dual-head motor 30 is located between the two support base assemblies 20. The output shafts at both ends of the dual-head motor 30 are detachably connected to the two rotating shafts 40 via couplings. Each rotating shaft 40 is helically connected to the two sliding members 203 on the corresponding support base assembly 20. Each rotating shaft 40 has a first helical part 401 and a second helical part 402. The first helical part 401 and the second helical part 402 have opposite rotation directions, and the first helical part 401 and the second helical part 402 are helically connected to the two sliding members 203 respectively.

[0031] Specifically, in order to realize the helical transmission connection between the first helical part 401 and the second helical part 402 and the two sliding members 203 respectively, each fixed seat 202 has a groove 2021, and the two sliding members 203 are slidably disposed in the groove 2021. The two side walls of the sliding member 203 are in contact with the groove side wall of the groove 2021, and the first helical part 401 and the second helical part 402 are threadedly connected to the corresponding sliding member 203 respectively.

[0032] It should be noted that when the dual-head motor 30 is activated, the output shafts at both ends of the dual-head motor 30 rotate in the same direction, driving each of the rotating shafts 40 to rotate accordingly, and causing the lifting seats 201 on the two support seats assemblies 20 to rise and fall together. In addition, when the lifting seat 201 rises to the specified height, the dual-head motor 30 can be removed to reduce the cost of use.

[0033] Furthermore, to improve the stability of the lifting seat 201 during vertical movement, each support assembly 20 further includes several guide rods 204. The bottom of the lifting seat 201 has several lifting holes (not shown in the figure). One end of the guide rod 204 is fixedly connected to the fixed seat 202, and the other end of the guide rod 204 extends into the lifting hole, with the rod wall of the guide rod 204 fitting against the hole wall of the lifting hole. It should be noted that when the dual-head motor 30 is activated, the guide rod 204 slides relative to the lifting hole.

[0034] Furthermore, to improve the overall stability of the dry-type transformer body 10, each support assembly 20 also includes several telescopic components 205, the two ends of which are fixedly connected to the lifting seat 201 and the fixed seat 202, respectively.

[0035] Specifically, each of the telescopic components 205 includes a rod 2051, a sleeve 2052, and a fastener 2053. One end of the rod 2051 is raised and lowered inside the sleeve 2052. The end of the rod 2051 facing away from the sleeve 2052 is connected to the lifting seat 201. The end of the sleeve 2052 facing away from the rod 2051 is connected to the fixing seat 202. The connection method includes, but is not limited to, welding. The fastener 2053 is threaded to the side wall of the sleeve 2052 and abuts against or separates from the side wall of the rod 2051.

[0036] It should be noted that the fastener 2053 is preferably a bolt. When it is necessary to adjust the height of the lifting seat 201, first loosen the fastener 2053 and separate the end of the fastener 2053 from the side wall of the rod 2051. Then, activate the dual-head motor 30 and move the lifting seat 201 upward to the predetermined position. Then, tighten the fastener 2053 and make the end of the fastener 2053 abut against the side wall of the rod 2051 to achieve auxiliary fixation of the height position of the lifting seat 201.

[0037] In summary, the adjustable support base for dry-type transformers based on the embodiments of this application is explained, which provides advantages such as adjustable support base height, reduced power strip usage, and lower operating costs.

[0038] It is worth mentioning that, in this embodiment, the adjustable support base for the dry-type transformer has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the adjustable support base for the dry-type transformer provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0039] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
