Description

Technical Field

[0001] The utility model relates to the technical field of box-type substations, and more particularly to a box-type substation with a compact structure. Background Art

[0002] A prefabricated substation is a complete outdoor system consisting of high-voltage switchgear, power transformers, low-voltage switchgear, and other components. It transmits power from high-voltage to low-voltage systems. Because prefabricated substations are suitable for residential areas, urban public substations, bustling urban areas, and construction power supplies, users can choose a prefabricated substation based on different usage conditions and load levels. Since its introduction, prefabricated substations have developed rapidly. With the continuous upgrading and transformation of urban distribution networks, prefabricated substations have become a mainstream product of power transformation and distribution equipment in my country.

[0003] Several patent documents related to box-type substations have been published in the prior art. Chinese patent application number CN201320293846.X discloses a compact box-type substation comprising a rectangular housing with a top cover disposed on the top to prevent rainwater from entering the compact box-type substation. Support columns are disposed on the top, bottom, or between the top and bottom of the housing, with two or more support columns connected to mounting beams for mounting electrical components. The compact box-type substation of the utility model eliminates high-voltage and low-voltage cabinets from its internal structure, assembling high-voltage and low-voltage components directly within the housing. Electrical components are mounted via mounting beams, eliminating the need for an operating corridor. Currently, box-type substations generally have remote control devices, making on-site operation rare. This reduces the overall size of the box-type substation by approximately one-third, reducing costs accordingly and making it suitable for deployment in urban streets and residential areas.

[0004] In the above patents, the installation method of the transformer and metering incoming line cabinet is relatively cumbersome, and a large space is required in the substation, which results in the substation being too large and affecting the convenience of use. For this reason, we propose a compact box-type substation. Utility Model Content

[0040] In this embodiment, the installation mechanism includes a moving assembly and a driving assembly. The moving assembly and the driving assembly are both arranged in the installation groove 7, and the moving assembly and the driving assembly are connected.

[0041] Specifically, the moving assembly includes a pressure plate 8, a screw 9, a threaded barrel 10, a guide rod 11 and a slide 12. The screw 9 is rotatably connected to the mounting groove 7, the threaded barrel 10 is threadedly connected to the surface of the screw 9, the pressure plate 8 is fixedly connected to the bottom of the threaded barrel 10, and two guide rods 11 and two slides 12 are each provided. The two guide rods 11 are fixedly connected to the mounting groove 7, the two slides 12 are fixedly connected to the surface of the threaded barrel 10, and the two slides 12 slide with the two guide rods 11.

[0042] In this embodiment, the rotation of the screw 9 causes the threaded barrel 10 to move on the surface of the screw 9. When the screw 9 is reversed, the threaded barrel 10 moves downward on the surface of the screw 9. The movement of the threaded barrel 10 drives the pressure plate 8 to move downward, and the metering incoming line cabinet 4 and the transformer 5 are clamped and fixed by the pressure plate 8. The guide rod 11 is designed to facilitate sliding cooperation with the slide plate 12.
