Description

Technical Field

[0001] The utility model relates to a voltage transformer installation device, in particular to a voltage transformer installation device suitable for a medium voltage main distribution board, which is convenient for assembly and disassembly, has a wiring function, and can be quickly opened when maintenance, inspection, and repair are required. Background Art

[0002] In existing medium-voltage switchgear, voltage transformers are mostly installed in a fixed manner, that is, they are installed on a fixed bracket using fasteners such as bolts, leaving a small installation space. When inspection, maintenance, and other operations are required, the manual operating space is small, posing a safety risk.

[0003] Existing voltage transformers are mostly fixed installations with narrow installation spaces, which leaves insufficient room for manual inspection, maintenance and other operations. If disassembly is required, it is even more inconvenient. Summary of the Invention

[0004] The purpose of the utility model is to facilitate manual inspection, maintenance and wiring, and to provide a voltage transformer installation device. By installing the voltage transformer on a flippable installation device, the problems of subsequent manual inspection, maintenance and wiring are effectively solved.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is: a voltage transformer installation device, including a voltage transformer lower mounting plate, a voltage transformer upper mounting plate, a voltage transformer, and a flip axis. The voltage transformer is installed in the cabinet through the voltage transformer lower mounting plate and the voltage transformer upper mounting plate, wherein a flip axis is connected between the voltage transformer lower mounting plate and the cabinet, and the voltage transformer lower mounting plate can rotate and flip around the flip axis.

[0006] Furthermore, the voltage transformer is fixedly connected to the voltage transformer upper mounting plate and the voltage transformer lower mounting plate by bolts.

[0007] Furthermore, after the turning shaft passes through the lower mounting plate of the voltage transformer, limiting sleeves are sleeved on both ends and fixed with set screws.

[0008] Furthermore, the relevant traces used to bind the voltage transformer on the flip axis are flipped.

[0009] Furthermore, both sides of the lower mounting plate of the voltage transformer and the upper mounting plate of the voltage transformer are fixedly connected in the cabinet by detachable bolts.

[0010] The beneficial effects of the utility model are:

[0011] (1) Compared with the existing technology, this application is more flexible and greatly facilitates the subsequent maintenance, inspection, repair and other operations of the equipment.

[0012] (2) The main parts of the voltage transformer installation device are laser cut, CNC bent, assembled and overlapped. They have high design precision and flexible rotating shafts, which effectively ensure the operability of the structure.

[0013] (3) Compared with the prior art, the utility model can be quickly disassembled and flipped, which greatly facilitates subsequent maintenance work. After flipping, the voltage transformer is located outside the cabinet, and the free space inside the cabinet is larger, which is convenient for inspection and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic structural diagram of a voltage transformer installation device of the present utility model. DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 As shown, a voltage transformer installation device of the present invention includes a voltage transformer lower mounting plate 1, a voltage transformer upper mounting plate 2, a voltage transformer 3, a turning shaft 4, a limit sleeve 5, a set screw 6, and a bolt 7 including a spring washer and a flat washer.

[0017] Among them, the voltage transformer 3 is fixedly connected to the upper mounting plate 1 of the voltage transformer and the lower mounting plate 2 of the voltage transformer by bolts 7, the flip axis 4 passes through the lower mounting plate 1 of the voltage transformer, and the limit sleeves 5 are respectively located on both sides of the flip axis 4 and are fixed by set screws 6, thereby achieving a limiting effect on the lower mounting plate of the voltage transformer, and the relevant wiring can be bound to the flip axis.

[0018] After the voltage transformer assembly is installed, place the two side parts of the flip axis 4 that extend beyond the voltage transformer lower mounting plate 1 on the corresponding mounting holes of the cabinet, and connect and fix the voltage transformer lower mounting plate 1 and the voltage transformer upper mounting plate 2 to the cabinet with bolts 7.

[0019] When in use, after opening the cabinet door, remove the bolts 7 between the voltage transformer lower mounting plate 1, the voltage transformer upper mounting plate 2 and the cabinet body, pull the voltage transformer upper mounting plate 1 outward, flip the voltage transformer mounting assembly out of the cabinet body, and inspect and repair the voltage transformer assembly.

[0020] After the operation is completed, flip the voltage transformer installation assembly upward to the installation position, install the bolts 7 that were previously removed, restore the voltage transformer installation assembly to its original position, and close the cabinet door.

[0021] The specific implementation method of the present invention is as follows: (1) the voltage transformer installation assembly is installed according to the assembly drawing; (2) the voltage transformer installation assembly is checked for shaking and whether the voltage transformer installation assembly can be flexibly rotated along the flip axis (4). If not, it is necessary to check whether the parts are deformed during installation. If deformed, the parts need to be replaced.
