Description

Technical Field

[0001] This utility model relates to the field of power transmission box technology, and in particular to an internal reversing structure of a power transmission box that is easy to install. Background Technology

[0002] Transmission cabinets refer to electrical products used in power systems for power generation, transmission, distribution, power conversion, and consumption, which play a role in switching, control, or protection, with voltage levels ranging from 3.6kV to 550kV. They mainly include several categories such as high-voltage circuit breakers, high-voltage disconnect switches and grounding switches, high-voltage load switches, high-voltage automatic reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switchgear. The high-voltage switchgear manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry and occupies a very important position in the entire power industry.

[0003] Transmission boxes typically house voltage conversion structures, usually transformers. During installation, the transformers are directly installed inside the box and supported and fixed by an internal support frame. Due to the limited space inside the box, installation is difficult and requires improvement by setting up a transformer base frame structure that facilitates installation. Utility Model Content

The supporting inner plate is located inside the box body. Side sliding grooves are provided on both sides of the supporting inner plate. A displacement slide is slidably mounted on the top of the supporting inner plate through the side sliding grooves. A rotating shaft is movably mounted on the top of the displacement slide through a bearing. The top of the rotating shaft is connected to the fixed frame. Multiple fixed arm plates are provided on the sides of the fixed frame. A caster wheel is mounted on one side of the bottom of the fixed frame.

[0007] Preferably, a vertical plate is fixedly connected to one end of the fixed frame, and a handle is provided on the outer side of the vertical plate.

[0008] Preferably, a strip-shaped groove is provided on the side of the handle, and multiple wire seats are provided inside the strip-shaped groove, with wire holes provided inside the wire seats.

[0009] Preferably, one end of the fixed frame is provided with two side support plates, and the top of the side support plates is threadedly connected with a locking screw.

[0010] Preferably, the front end of the inner support plate has two limiting screw holes, and the bottom end of the locking screw is threaded into the inside of the limiting screw holes.

[0011] Preferably, the front end of the inner support plate is provided with a front groove, and the universal wheel is placed inside the front groove. The outside of the box body is provided with a box door. When the inner support plate of this application slides completely into the box body, the displacement slide block slides to the end position of the inner support plate, and the universal wheel at the bottom of the inner support plate is inside the front groove. This structural design will not affect the normal closing of the box door. Moreover, the box door of this application is a metal box door, and the connection between the box door and the box body can be made by conventional hinges.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This application features a supporting inner plate and a fixed frame inside the enclosure. The bottom end of the fixed frame slides on the supporting inner plate via a displacement slide block and can also swing to both sides via a rotating shaft. When installing electrical equipment, the fixed frame is pulled out and swung to both sides. After adjusting the fixed frame to a position and angle convenient for maintenance, the equipment can be installed on top of the fixed frame. After the electrical equipment on top of the fixed frame is installed, the fixed frame is pushed back into the enclosure, with the fixed frame positioned on top of the supporting inner plate. Then, the locking screw is rotated, and the bottom end of the locking screw rotates into the limit screw hole to limit the fixed frame. This structural design facilitates the operator's maintenance and installation of electrical equipment. Attached Figure Description
