Technical Field

[0001] This utility model relates to the field of European-style prefabricated substation equipment, specifically a protective plate for the high-voltage compartment and transformer compartment of a European-style prefabricated substation. Background Technology

[0002] A prefabricated substation is a complete set of products that integrates high-voltage switchgear, distribution transformers, and low-voltage switchgear. It features strong integration, compact structure, small size, minimal footprint, ability to be located near load centers, improved power quality, reduced losses, short power supply cycle, flexible site selection, strong environmental adaptability, convenient installation and use, safe and reliable operation, low investment, and quick returns. The substation is divided into a high-voltage compartment, a transformer compartment, and a low-voltage compartment. The high-voltage compartment adopts a robust and reliable compact design with comprehensive anti-misoperation interlocking functions, high reliability, and convenient maintenance.

[0003] A search revealed that utility model patent CN209981872U discloses a compact box-type transformer substation, including an outdoor box. The outdoor box has a top plate on its upper side, which is shaped like a box with a high center and low ends. Guide grooves are installed on both sides of the outdoor box, and roller shutter doors are placed in the guide grooves. The outdoor box contains two transformers, high-voltage equipment, low-voltage equipment, and incoming cables. The high-voltage equipment has an air chamber, and the left and right sides of the air chamber are respectively equipped with a left incoming bushing and a right incoming bushing connected to the incoming cables. The high-voltage side of the transformer housing is equipped with a fully insulated high-voltage outgoing bushing, and the back of the high-voltage equipment is equipped with an outgoing bushing connected to the high-voltage outgoing bushing. The low-voltage side of the transformer housing is equipped with a low-voltage outgoing bushing composed of a conductive rod and a terminal block, which extends into the low-voltage equipment and makes an electrical connection with the low-voltage components.

[0004] Currently, protective barriers are installed between the transformer room and the high-voltage room in prefabricated substations. Traditional protective barriers consist of only one layer, resulting in low strength and poor reliability. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a protective plate for the high-voltage room and transformer room of a European-style box-type substation, which solves the problem that the traditional protective plate only consists of one layer of board, resulting in low strength and poor reliability, when an isolation protective plate is installed between the transformer room and the high-voltage room of the box-type substation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective plate for the high-voltage compartment and transformer compartment of a European-style prefabricated substation, comprising a prefabricated substation housing, wherein a protective plate is integrally formed inside the prefabricated substation housing, and a reinforcing rib is attached to the right side of the protective plate, with the upper and lower ends of the reinforcing rib abutting against the inner wall of the prefabricated substation housing. Multiple positioning blocks are fixedly connected to the right side of the protective plate, the positioning blocks penetrating the reinforcing rib and slidably connected to it, and a hollow sleeve is fixedly connected to the reinforcing rib. The positioning blocks are inserted into the hollow sleeve, and a locking pin is slidably connected inside the positioning blocks, penetrating the hollow sleeve and inserting into it. A spring is provided inside the positioning blocks, and a limiting sleeve is fixedly connected to the outer wall of the hollow sleeve. A push block is slidably connected inside the limiting sleeve, one end of the push block abutting against the locking pin, and a button is fixedly connected to the other end of the push block.

[0007] Preferably, one end of the spring is fixedly connected to the locking pin, and the other end of the spring is fixedly connected to the inner surface of the positioning block. By using the spring, a spring force can be applied to the locking pin, ensuring that the locking pin is always inserted into the hollow sleeve.

[0008] Preferably, a protective sleeve is fixedly connected to both the button and the hollow sleeve, and the protective sleeve is located on the outside of the push block. The protective sleeve prevents the button and push block from falling off.

[0009] Preferably, a travel limit block is fixedly connected to the button, and the position of the travel limit block corresponds to the position of the limit sleeve. The travel limit block limits the travel of both the button and the push block.

[0010] Preferably, a locking block is internally engaged with the reinforcing rib, and a decorative cover is fixedly connected to the locking block, with the position of the decorative cover corresponding to the horizontal position of the reinforcing rib. The decorative cover serves to conceal and enhance the aesthetics of the installation positions of the reinforcing rib and the protective plate.

[0011] Preferably, the reinforcing rib includes multiple transverse and longitudinal ribs, which are arranged intersectingly, and the locking block engages with the intersection of the transverse and longitudinal ribs. The intersecting arrangement of the transverse and longitudinal ribs enhances the structural strength of the reinforcing rib.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a reinforcing rib at the protective plate of the transformer box body. The reinforcing rib consists of transverse ribs and longitudinal ribs, and the transverse ribs and longitudinal ribs are arranged in a crisscross pattern, which greatly improves the strength of the protective plate and makes the protection between the high voltage chamber and the transformer chamber on the left and right sides of the transformer box body more reliable.

[0014] 2. This utility model achieves rapid positioning, installation and locking of the protective plate and the reinforcing rib through the coordinated design of the positioning block, hollow sleeve and spring clip. At the same time, the decorative cover is fixed to the installation connection between the reinforcing rib and the protective plate, which not only enhances the overall mechanical strength, but also facilitates quick disassembly during maintenance.
