Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of voltage transformers, and in particular to a quick-install voltage transformer. Background Technology
[0002] Voltage transformers are similar to transformers, both being instruments used to transform voltage. However, transformers transform voltage to facilitate the transmission of electrical energy, and therefore have a large capacity, typically measured in kilovolt-amperes or megavolt-amperes. Voltage transformers, on the other hand, transform voltage primarily to power measuring instruments and relay protection devices, to measure line voltage, power, and electrical energy, or to protect valuable equipment, motors, and transformers in the line when a fault occurs.
[0003] Voltage transformers are typically fixed or bolted to support columns during installation, and then connected to corresponding equipment or lines in the circuit. Because voltage transformers are usually bolted or welded to support columns and then connected to corresponding equipment or lines, the installation of voltage transformers is quite difficult.
[0004] Therefore, based on the above-mentioned technical problems, this application proposes a quick-installation voltage transformer with a simple structure and easy installation. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a quick-installation voltage transformer with a simple structure and easy installation.
[0006] To achieve the above objectives, this utility model provides a quick-installation voltage transformer, including a voltage transformer body, a sliding seat, and a fixed seat. The voltage transformer body is installed on the bottom end of the sliding seat by pre-set screws. The fixed seat has symmetrically arranged guide portions on both sides, and the sliding seat has symmetrically arranged recessed portions on both sides, wherein the recessed portions are slidably fitted onto the guide portions. The top surface of the fixed seat has at least two through-hole fixing holes, which are fitted with pre-set screws to fix the fixed seat to the distribution cabinet. One side end of the fixed seat has at least one through-hole primary locking hole, and one side end of the sliding seat has at least one secondary locking hole that mates with the fixing holes. The secondary locking hole is used to connect with the primary locking hole via pre-set screws, thereby relatively restricting the sliding of the sliding seat on the fixed seat.
[0007] Furthermore, the guide portion has an L-shaped structure, and the recessed portion has a C-shaped structure.
[0008] Furthermore, at least two through primary mounting holes are formed on the bottom end face of the sliding seat, and at least two through secondary mounting holes are formed on the top end face of the voltage transformer body. The primary mounting holes are used to connect and cooperate with the secondary mounting holes so that the voltage transformer body and the sliding seat are fixedly connected.
[0009] The present invention adopts the above-described solution, and its beneficial effects are as follows:
[0010] By installing the fixed base in the distribution cabinet and the sliding base on the voltage transformer body, the installation of the voltage transformer body can be achieved simply by sliding the recess and the guide part together. The structure is simple and greatly reduces the installation difficulty. Secondly, by opening relevant locking holes, the sliding fit between the recess and the guide part can be relatively restricted, which can reduce the sliding wear between the two and reduce the cost of later maintenance. Furthermore, when it is necessary to inspect the voltage transformer body, the screws connecting the primary locking hole and the secondary locking hole can be loosened to pull out the voltage transformer body for inspection.

[0017] To facilitate understanding of this utility model, a more complete description of it is provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0018] See appendix Figure 1-5As shown, in this embodiment, a quick-install voltage transformer includes a voltage transformer body 1, a sliding seat 2, and a fixed seat 3. The voltage transformer body 1 is installed on the bottom of the sliding seat 2 by pre-set screws. The fixed seat 3 has symmetrically arranged guide portions 31 on both sides, and the sliding seat 2 has symmetrically arranged recesses 21 on both sides. The guide portions 31 are L-shaped, and the recesses 21 are C-shaped, with the recesses 21 slidably fitted onto the guide portions 31. The top surface of the fixed seat 3 has at least two through-hole fixing holes 32, which are fixedly connected to the distribution cabinet by pre-set screws. The bottom surface of the sliding seat 2 has at least two, preferably eight, through-hole primary mounting holes 23 (four of which are located at the four corners of the bottom surface of the sliding seat 2, and the remaining holes are located at the center of the bottom surface of the sliding seat 2, and the recesses 21 are not symmetrically arranged on either side). The voltage transformer body 1 has four clearance grooves to avoid the primary mounting holes 23 at the center position. At least two, preferably four, through secondary mounting holes 11 are formed on the top surface of the voltage transformer body 1. The secondary mounting holes 11 are preferably located at the four corners of the top surface of the voltage transformer body 1. The primary mounting holes 23 are used to connect with the secondary mounting holes 11, so that the voltage transformer body 1 is fixedly connected to the sliding seat 2. Through the positional distribution of the primary mounting holes 23 and the secondary mounting holes 11, voltage transformer bodies 1 of different specifications can be installed on the sliding seat 2, improving the compatibility range of the installed voltage transformer. In addition, unlike the traditional voltage transformer with the overall direction facing upward after installation, in this embodiment, in order to cooperate with the sliding fit between the fixed seat 3 and the sliding seat 2 and the spatial distribution of other electrical components, the voltage transformer body 1 is oriented downward after installation.
[0019] See appendix Figure 3-5 As shown, in this embodiment, at least one, preferably two, through primary locking holes 33 are formed on one side of the fixed base 3, and at least one, preferably two, secondary locking holes 22 are formed on one side of the sliding base 2, which cooperate with the fixed hole 32. The secondary locking holes 22 are used to cooperate with the primary locking holes 33 through preset screws to relatively restrict the sliding of the sliding base 2 on the fixed base 3, so as to avoid the sliding during non-maintenance periods from affecting the normal operation of the voltage transformer body 1 and ensure the stability of the operation of the voltage transformer body 1.
[0020] It should be noted that during the assembly stage of production, the aforementioned mounting base 3 is first fixedly connected to the mounting frame of the distribution cabinet by means of pre-set screws passing through the fixing holes 32. See Appendix. Figure 1 , 2As shown; when the distribution cabinet has been installed at the corresponding work location and the electrical equipment inside the cabinet is installed, the operator installs the sliding seat 2 onto the voltage transformer body 1 using the pre-set screws, and then moves the sliding seat 2 in the direction shown by the arrow in the figure, so that it slides and is embedded in the fixed seat 3; in addition, after the sliding seat 2 is slidably embedded in the fixed seat 3, in order to prevent the recess 21 from sliding back and forth on the guide part 31 due to external collisions or other factors, the pre-set screws pass through the primary and secondary mounting holes 11, so that one end face of the sliding seat 2 is relatively fixed to one end face of the fixed seat 3, thereby relatively restricting the back and forth sliding of the sliding seat 2 when not under maintenance, reducing the wear between the two and reducing subsequent maintenance costs.
[0021] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any modifications or alterations made by those skilled in the art to the technical solution of this utility model without departing from its scope are equivalent embodiments of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from its scope should be covered within the protection scope of this utility model.
