Technical Field

[0001] This utility model relates to the field of power transformer technology, and specifically discloses a power transformer with adjustable height. Background Technology

[0002] Power transformers are indispensable key equipment in power systems, widely used in energy metering, relay protection, system monitoring, and other fields. They are typically installed in various locations such as substations, distribution cabinets, or transmission lines to proportionally transform high voltage or high current in the primary circuit into low voltage or low current signals suitable for secondary equipment. During actual installation, due to differences in the height of the on-site installation foundation (such as platforms, supports, or cabinets), line layout requirements, or the need for later maintenance and replacement, the installation height of the transformer body relative to its installation foundation or connection point often needs to be finely adjusted to ensure that it meets electrical performance requirements, safety clearance regulations, and proper coordination with other equipment.

[0003] However, existing power transformers generally have certain limitations in height adjustment. Traditional fixed installation structures are difficult to cope with the needs of changing installation heights, and some solutions with adjustment functions are usually not convenient or stable enough. Common adjustment methods may involve complex assembly, multi-step operation using special tools, or difficulty in ensuring the stability of the equipment and the reliability of long-term operation after adjustment.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-3 An adjustable height power transformer includes a transformer body 1 and a base 2. A mounting plate 3 is provided on the top of the base 2. A slide block 4 is fixedly connected to the bottom of the base 2. A wedge block 5 is slidably connected to the upper end surface of the slide block 4. A support rod 6 is slidably connected through the center of the upper end surface of the base 2. A roller 7 is installed at the bottom of the support rod 6. The roller 7 abuts against the inclined surface of the wedge block 5. A spring 8 is sleeved on the outer wall of the support rod 6 between the top of the base 2 and the roller 7.

[0021] In this embodiment: the height-adjustable power transformer has a sliding block 5 supported by a slide block 4 inside the base 2. A support rod 6 is slidably connected above the base 2. The roller 7 at the bottom of the support rod 6 abuts against the inclined surface of the wedge block 5. Rotating the screw 11 on the side wall of the base 2 pushes the wedge block 5 to move horizontally through the rotating plate 14 and the rotating seat 13. Its inclined surface forces the roller 7 to drive the support rod 6 to rise and fall vertically, thereby lifting or lowering the transformer body 1 connected to the mounting plate 3 above by the shim 15 and the fixing bolt 16, thus realizing height adjustment. The spring 8 provides a downward preload to ensure that the roller 7 is in close contact with the wedge block 5 and assists in resetting. The slide cylinders 9 and guide rods 10 on both sides of the base 2 guide the mounting plate 3 to rise and fall stably. The support plate 20 at the top of the support rod 6 contacts the mounting plate 3 and its wear-resistant coating reduces wear. The removable cover plate 19 on the front side of the base 2 facilitates maintenance of the internal mechanism. The fixing plates 21 on both sides of the base 2 provide mounting points. The overall structure is compact and the adjustment process is convenient and stable.

[0022] As a technical optimization of this utility model, sliding cylinders 9 are installed through the top left and right sides of the base 2, and guide rods 10 are slidably connected through the inner sides of the two sliding cylinders 9. The top ends of the two guide rods 10 are fixedly connected to the lower end face of the mounting plate 3.

[0023] In this embodiment: the sliding cylinders 9 on both sides of the top of the base 2 and the guide rods 10 that slide through them provide precise vertical guidance for the mounting plate 3, limit its horizontal sway, ensure smooth lifting and accurate positioning, and improve the structural stability after adjustment.

[0024] As a technical optimization of this utility model, a screw 11 is threadedly connected to the left side wall of the base 2. One end of the screw 11 is fixedly connected to a handle 12, and the other end extends into the interior of the base 2 and is fixedly connected to a rotating plate 14. A rotating seat 13 is fixedly connected to the left side wall of the wedge block 5, and the rotating plate 14 is rotatably connected to the interior of the rotating seat 13.

[0025] In this embodiment: the screw 11 threaded through the side wall of the base 2, the handle 12 at its outer end and the rotating plate 14 at its inner end, and the rotating seat 13 fixed on the wedge block 5 form a manual drive mechanism; rotating the handle 12 can smoothly push the wedge block 5 to slide horizontally through the threaded transmission, which is labor-saving, precise and requires no additional tools.

[0026] As a technical optimization of this utility model, a gasket 15 is fixedly connected to the bottom of the transformer body 1, and two screw holes are opened on the upper end face of the mounting plate 3. The gasket 15 is detachably connected to the mounting plate 3 through the screw holes and the fixing bolt 16.

[0027] In this embodiment, the gasket 15 at the bottom of the transformer body 1 is connected to the screw hole on the mounting plate 3 by fixing bolts 16, so as to realize the quick and reliable installation and disassembly of the transformer body 1 and the mounting plate 3, which facilitates the replacement or maintenance of the transformer.

[0028] As a technical optimization of this utility model, the front opening of the base 2 and the corner of the inner wall are all fixedly connected with pads 17. The outer wall of the pads 17 is provided with mounting holes 18. The outer side of the multiple pads 17 is provided with cover plates 19. The cover plates 19 are detachably connected to the base 2 by bolts and mounting holes 18.

[0029] In this embodiment: the pad 17 and its mounting hole 18 at the corner of the front opening of the base 2, together with the detachable cover plate 19, conveniently seal the internal space of the base 2, protect the internal adjustment mechanism from environmental influences, and facilitate opening for inspection or maintenance.

[0030] As a technical optimization of this utility model, the top end of the support rod 6 is fixedly connected to a support plate 20 that abuts against the lower end surface of the mounting plate 3, and the upper end surface of the support plate 20 is coated with a wear-resistant coating.

[0031] In this embodiment: the support plate 20 fixed at the top of the support rod 6 increases the contact area with the mounting plate 3, providing a more uniform support force; the wear-resistant coating on its surface effectively reduces frictional wear with the mounting plate 3 during lifting and extending the service life of key contact components.

[0032] As a technical optimization of this utility model, a fixing plate 21 is fixedly connected to the lower left and right sides of the outer wall of the base 2, and a fixing hole is opened through the outer wall of the fixing plate 21.

[0033] In this embodiment, the fixing plates 21 with fixing holes fixed on the lower sides of the outer wall of the base 2 provide a solid installation foundation for the entire transformer device (including the base 2), ensuring the stability of the entire device during operation or adjustment.

[0034] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the height of the transformer body 1, the operator manually rotates the handle 12 located on the left side wall of the base 2, which drives the screw 11 fixedly connected to it to rotate. Since the screw 11 is threadedly connected to the side wall of the base 2, the screw 11 moves into the base 2 while rotating. The rotating plate 14 fixed at the inner end of the screw 11 moves accordingly and pushes the rotating seat 13 rotatably connected to it. The rotating seat 13 is fixed to the left side of the wedge block 5, thereby driving the wedge block 5 to slide horizontally on the slide block 4 at the bottom of the base 2. The inclined surface on the wedge block 5 moves accordingly, generating an upward thrust on the roller 7 that abuts against its inclined surface. This thrust overcomes the preload of the spring 8 sleeved on the outer wall of the support rod 6, pushing the roller 7 and the support rod 6 connected to it. The base 2 slides vertically upward through the through hole on the upper surface; the support plate 20 at the top of the support rod 6 rises accordingly, lifting the mounting plate 3 in contact with it; the lifting and lowering of the mounting plate 3 is precisely guided by the guide rods 10 passing through the top slide cylinder 9 of the base 2 on its left and right sides, ensuring smooth vertical movement; finally, the current transformer body 1, fixed on the mounting plate 3 (through the gasket 15 and fixing bolt 16), is lifted; if the handle 12 is rotated in the opposite direction to make the wedge block 5 slide to the left, under the downward pressure of the spring 8, the roller 7 slides down along the inclined surface of the wedge block 5, driving the support rod 6, the mounting plate 3, and the current transformer body 1 to descend; the removable cover plate 19 on the front side of the base 2 facilitates access to the internal mechanism for maintenance, and the fixing plates 21 on the lower sides of the base 2 are used to fix the entire device on the mounting base.
