Description

Technical Field

[0001] The utility model relates to a voltage transformer, in particular to a herringbone-shaped combined voltage transformer. Background Art

[0002] The voltage transformer is generally installed in the voltage transformer cabinet of the ring network cabinet. It is mainly used to obtain low voltage for the entire ring network cabinet or ring network box, and supply low voltage working voltage to the operating mechanism or other secondary components.

[0003] At present, conventional voltage transformers are generally installed in groups of three, and the three voltage transformers in the same group are usually arranged horizontally in a straight line. This arrangement occupies a relatively large space and is not compact enough in structure. It is not convenient to reduce the volume of the cabinet used to install the voltage transformer, making the overall space of the cabinet relatively large. Therefore, there are many inconveniences in actual use.

[0004] In view of this, an improved herringbone combined voltage transformer is proposed to solve the above technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing voltage transformer, such as its structural layout being not compact enough and occupying a relatively large area, the technical problem to be solved is to provide an improved herringbone combined voltage transformer.

[0006] The technical solution is: a herringbone-shaped combined voltage transformer, including voltage transformer a, voltage transformer b, voltage transformer c and a mounting plate, and also including a positioning sleeve, a positioning nut and a clamping piece. The voltage transformer a, voltage transformer b and voltage transformer c are a group and are mounted on the mounting plate in a herringbone-shaped combination. The bottom outer sides of the voltage transformer a, voltage transformer b and voltage transformer c are all provided with positioning sleeves. Positioning nuts are respectively embedded on the mounting plate near the positioning sleeves, and the positioning sleeves are aligned with the positioning nuts. Clamping pieces are respectively provided between the voltage transformer a, voltage transformer b, voltage transformer c and the mounting plate.

[0007] Furthermore, the clamping member includes a clamping seat and a clamping block. The bottoms of the voltage transformer a, voltage transformer b and voltage transformer c are respectively provided with clamping blocks, and the mounting plate is provided with a clamping seat that can be clamped and adapted with the clamping blocks.

[0008] Furthermore, it also includes a limit block, and each end of the card seat is provided with a limit block.

[0009] Furthermore, mounting holes are respectively provided at the four corners of the mounting plate.

[0010] Furthermore, the upper end of the positioning sleeve is provided with a rounded bevel.

[0011] Furthermore, a countersunk screw can be installed in the rounded bevel to cooperate with the positioning nut threaded connection.

[0012] The utility model has the following advantages: by arranging the voltage transformer a, the voltage transformer b and the voltage transformer c in a triangular shape, compared with the traditional straight-line horizontal arrangement, it is beneficial to proportionally reduce the size of the inner cabinet for installing the voltage transformer and shorten the length of the outer box, thereby helping to save costs and make the installation structure of the device more compact. Compared with some project areas with land restrictions or arable land red line restrictions, the improved product has more advantages; and the assembly structure of the positioning sleeve, the positioning nut and the clamping piece is beneficial to the purpose of quick installation and fixation of the device, and the operation is convenient.

For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. A person skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0020] Example: The utility model provides a herringbone combined voltage transformer, see Figures 1 to 5 As shown, it includes voltage transformer a1, voltage transformer b2, voltage transformer c3, mounting plate 4, positioning sleeve 7, positioning nut 8 and clamping piece. Voltage transformer a1, voltage transformer b2 and voltage transformer c3 are grouped together and mounted on the mounting plate 4 in a herringbone-shaped assembly, which can reduce space occupation and achieve the purpose of compact structure layout. Mounting holes 40 are respectively provided at the four corners of the mounting plate 4 to facilitate the convenient fixing and mounting of the assembled voltage transformers in the same group on the cabinet; the outer sides of the bottoms of the voltage transformers a1, voltage transformer b2 and voltage transformer c3 are all provided with positioning nuts. The positioning sleeve 7 has a rounded bevel on the upper end, which is convenient for installation and fixation using countersunk screws; the rounded bevel can be used to install countersunk screws and threadedly connect with the positioning nut 8, which is beneficial to keep the outer end of the positioning sleeve 7 flat; the mounting plate 4 is respectively embedded with a positioning nut 8 near the positioning sleeve 7, and the positioning sleeve 7 is aligned with the positioning nut 8, which is convenient for convenient installation and fixation of the voltage transformer a1, voltage transformer b2, and voltage transformer c3, and there are respectively provided with a clamping piece between the voltage transformer a1, voltage transformer b2, voltage transformer c3 and the mounting plate 4.

[0021] For further information, see Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the clamping member includes a clamping seat 5 and a clamping block 6. The bottoms of the voltage transformer a1, the voltage transformer b2 and the voltage transformer c3 are respectively provided with a clamping block 6, and the mounting plate 4 is provided with a clamping seat 5 that can be clamped and adapted with the clamping block 6.

[0022] In addition, see Figure 4 As shown, it also includes a limit block 50. A limit block 50 is provided at the end of each holder 5 to limit the block 6 so that the positioning sleeve 7 can be accurately aligned with the positioning nut 8, thereby facilitating the quick installation and fixation of the voltage transformer.

[0023] The voltage transformer a1, the voltage transformer b2 and the voltage transformer c3 are respectively clamped on the corresponding card holder 5 in a triangular combination. The voltage transformer a1, the voltage transformer b2 and the voltage transformer c3 can be accurately assembled on the card holder 5 through the limit block 50, so that the positioning sleeves 7 thereon can be aligned with the corresponding positioning nuts 8 respectively. Then, the countersunk screws can be screwed from the positioning sleeves 7 into the positioning nuts 8. In this way, the voltage transformer a1, the voltage transformer b2 and the voltage transformer c3 can be quickly installed and fixed, and the operation is convenient. Then, the mounting plate 4 equipped with the voltage transformer a1, the voltage transformer b2 and the voltage transformer c3 only needs to be fixed in the voltage transformer cabinet through the mounting hole 40.
