Description

Technical Field

[0001] This utility model relates to the field of voltage transformer technology, specifically a fully enclosed voltage transformer that is easy to install. Background Technology

[0002] Voltage transformers are similar to transformers in that they are instruments used to transform voltage. However, transformers transform voltage to facilitate the transmission of electrical energy, so their capacity is very large, usually measured in kilovolt-amperes or megavolt-amperes. On the other hand, voltage transformers transform voltage primarily to power measuring instruments, to measure line voltage, power, and electrical energy, or to protect valuable equipment, motors, and transformers in the event of a line fault. Therefore, voltage transformers have a very small capacity, generally only a few volt-amperes or tens of volt-amperes, and at most no more than one thousand volt-amperes.

[0003] Currently, fully enclosed voltage transformers are relatively heavy, and most of them are installed inside cabinets with limited space, making it difficult for workers to move them to the appropriate location inside the cabinet, thus hindering their installation. Summary of the Invention

[0004] The purpose of this utility model is to provide a fully enclosed voltage transformer that is easy to install, in order to solve the problem mentioned in the background art that the current fully enclosed voltage transformers are heavy and mostly installed inside cabinets with limited space, making it difficult for workers to move the fully enclosed voltage transformers to the corresponding positions inside the cabinets, thus making it inconvenient to install the fully enclosed voltage transformers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully enclosed voltage transformer that is easy to install, comprising a base, wherein a plurality of adjusting components are horizontally fixedly installed on the bottom of the base, and a sliding seat is fixedly connected to the bottom of the adjusting components. The transformer body is fixedly installed on the top of the base. The adjusting components include adjusting seats, connecting blocks and bolts. The adjusting seats are fixedly connected to the bottom surface of the base by bolts. An adjusting groove is provided in the adjusting seat, and a plurality of connecting blocks are slidably connected in the adjusting groove. The connecting blocks are fixed to the adjusting seat by bolts.

[0006] Preferably, the inner wall of the adjusting groove is provided with an irregular hole, and the connecting block is provided with a connecting hole on its surface at a position opposite to the irregular hole. The connecting hole and the irregular hole are connected by bolts.

[0007] Preferably, the sliding seat is fixedly connected to the bottom surface of the connecting block, and a sliding groove is provided at the bottom of the sliding seat, with fixing holes provided at both ends of the inner wall of the sliding groove.

[0008] Preferably, the sliding groove adopts a U-shaped structure design.

[0009] Preferably, a junction box is fixedly installed on one end face of the current transformer body, and a protective cover is rotatably connected to the surface of the junction box.

[0010] Preferably, the front end of the junction box surface is symmetrically provided with a rotating hole and a snap-fit ​​hole, and the snap-fit ​​hole is located below the rotating hole. The two ends of the protective cover surface are fixedly connected to a rotating rod at the opposite position of the rotating hole, and the rotating rod is rotatably connected in the rotating hole. The two ends of the protective cover surface are fixedly connected to a protrusion at the opposite position of the snap-fit ​​hole, and the protrusion is movably connected in the snap-fit ​​hole.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] like Figure 1-3 This is a schematic diagram of a preferred embodiment of the present invention, showing a fully enclosed voltage transformer that is easy to install. In this embodiment, the fully enclosed voltage transformer includes a base 1, with two sets of adjusting components 2 horizontally and parallelly fixed to the bottom of the base 1. Each adjusting component 2 includes a long, narrow adjusting seat 21, which is vertically fixed to the bottom surface of the base 1 by bolts 24. A continuous adjusting groove 23 is formed inside the adjusting seat 21 along its length, and two cuboid connecting blocks 22 are slidably connected within the adjusting groove 23.

[0025] In this embodiment, a through-hole 231 is provided on the side wall of the adjusting groove 23, and a circular connecting hole 221 is provided at the corresponding position on the connecting block 22. By tightening the bolt 24 through the through-hole 231 and the connecting hole 221, the connecting block 22 can be locked in any position within the adjusting groove 23, thereby achieving stepless adjustment of the lateral position.

[0026] In this embodiment, a sliding seat 3 is welded to the bottom of each connecting block 22. A U-shaped sliding groove 31 is formed on the bottom surface of the sliding seat 3, and threaded fixing holes 32 are symmetrically formed at both ends of the inner wall of the sliding groove 31. During installation, the sliding groove 31 is inserted into the external guide rail, and bolts are screwed through the guide rail and into the fixing holes 32 to quickly complete the fixing.

[0027] In this embodiment, the transformer body 4 is bolted to the top of the base 1, and the junction box 5 is fixed to the right side of the transformer body 4. The junction box 5 has symmetrically formed rotating holes 52 and snap-fit ​​holes 53 located below the rotating holes 52 on its front end surface. Cylindrical rotating rods 54 are fixedly connected to both sides of the protective cover 51 and are inserted into the rotating holes 52 to achieve opening and closing rotation. When the cover is closed, the protrusions 55 on its inner side engage with the snap-fit ​​holes 53 to form a self-locking mechanism, preventing vibration from causing the protective cover 51 to open accidentally.

[0028] Working principle

[0029] Installation procedure:

[0030] 1. Fix the adjusting seat 21 to the preset position at the bottom of the base 1 using bolts 24;

[0031] 2. Slide the connecting block 22 along the adjusting groove 23 to the required distance, and tighten the bolt 24 to fix it;

[0032] 3. Align the U-shaped sliding groove 31 of the sliding seat 3 with the mounting guide rail and push it in;

[0033] 4. Use bolt 24 to pass through the guide rail and lock it into the fixing hole 32 to complete the overall fixation;

[0034] 5. Open the protective cover 51 to connect the wires. After closing, the protrusion 55 will automatically lock in place.

[0035] The above description provides a more detailed explanation of the present invention in conjunction with specific embodiments. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present invention.
