Description

Technical Field

[0001] This utility model relates to the field of power equipment, specifically to a prefabricated switchgear. Background Technology

[0002] Switchgear is used in power transmission and distribution equipment to house electrical devices and protect them from external interference. Its modular design provides high flexibility and scalability. External power lines first enter the main control switch inside the cabinet via cable conduits, then are distributed through copper busbars, and finally connected to branch control switches via insulated cables, allowing for customized configuration of each branch circuit. Different types of switching components, such as vacuum circuit breakers, disconnectors, and load switches, can be flexibly selected and assembled within the switchgear to meet the needs of power transmission and distribution. It is also equipped with busbars, insulating supports, and anti-misoperation interlocking devices. By combining spring-operated, electromagnetic, or permanent magnet operating mechanisms with voltage and current transformers, and integrating overcurrent protection, grounding protection, undervoltage protection, and other relay protection devices, as well as temperature monitoring and arc flash protection devices, a complete secondary circuit control system is formed. This system monitors and provides relay protection for the main and branch circuits within the switchgear, ensuring effective control and protection of the circuits within the switchgear.

[0003] With the continuous construction of circuit systems and the increasing number of branch circuits, a single switchgear is insufficient to meet power distribution and transmission needs due to limited space. Therefore, multiple switchgear are typically configured in the distribution room, with one designated as the main switchgear responsible for primary power distribution. Other switchgear are used to further distribute power to the various branch circuits branched off from the main switchgear, ensuring sufficient power distribution and transmission capacity. While this configuration effectively addresses power distribution needs, cables are required to interconnect the multiple switchgears to maintain the transmission circuits. However, this results in numerous exposed cables on the exterior of the switchgear, making the distribution room appear cluttered and creating safety hazards, making the environment extremely dangerous. Furthermore, because the internal space of the switchgear is independent, if the busbars, insulation supports, switching elements, and protection devices are too large, the switchgear may not be able to accommodate the electrical equipment. Therefore, to address these shortcomings, the switchgear needs to be expanded to allow for better connection between the internal spaces of multiple switchgears, thus facilitating power distribution and transmission. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a prefabricated switchgear that facilitates the connection of the inner diameters of multiple switchgear cabinets to control the assembly space, thereby overcoming the deficiencies in existing technologies.

[0005] The technical solution adopted by this utility model is as follows: a prefabricated switch cabinet, including a cabinet body with an opening on one side and a cabinet door hinged to the opening end of the cabinet body. Two fixing plates are provided on the cabinet body, and hinges are provided on the two fixing plates respectively. One fixing plate is hinged to the side of the cabinet body near the cabinet door by the hinge, and the other fixing plate is hinged to the side of the cabinet body away from the cabinet door by the hinge. Two fixing slots are opened on the cabinet body, and the two fixing slots are respectively opened on the side walls on both sides of the cabinet body. The two fixing plates are movably fitted into the two fixing slots respectively. A locking device is provided between the fixing plates and the cabinet body. The locking device includes a first baffle on the cabinet, a second baffle on the fixed plate, and an n-shaped support plate between the first baffle and the second baffle. The first baffle and the second baffle are located on both sides of the hinge. Both the first baffle and the second baffle adopt an L-shaped structure. The top of the first baffle is installed on the outer wall of the cabinet, and the top of the second baffle is installed on the side of the fixed plate.

Next, through the slot 16 opened in the cabinet cover 11, the sealing plate 17 and sealing gasket 18 are pulled out, and then the support plate 8 is pulled out from the slot 16, allowing the fixing plate 3 to rotate. Then, by pushing the fixing plate 3 to rotate, the two sides of the hinge 4 are made parallel, and one side of the fixing plate 3 and the baffle 19 are used to create a closed space between two adjacent cabinets 1. Simultaneously, the internal cavities of adjacent cabinets 1 are connected through this closed space to expand the assembly space and connect the internal cavities of multiple cabinets 1. Next, reinsert the support plate 8 into the slot 16, ensuring that one side of the support plate 8 penetrates into the insert plate 10, and that the support plate 8 is inserted into the cavity surrounded by the first baffle 6 and the second baffle 7. Then, assemble the sealing gasket 18 onto the support plate 8, so that the sealing plate 17 contacts the top of the support plate 8, ensuring the integrity and sealing of the assembly. Finally, assemble the busbars, insulating supports, anti-misoperation interlocking devices, switching elements, transformers, protection devices, and other key components in sequence according to requirements, ensuring the efficient and safe operation of the entire power distribution system.

[0029] In this embodiment, the hinge 4 on the cabinet 1 allows one fixing plate 3 to be hinged to the side of the cabinet 1 near the cabinet door 2, and the other fixing plate 3 to be hinged to the side of the cabinet 1 away from the cabinet door 2. This design divides the space between two adjacent cabinets 1 into a closed space through the fixing plates 3, allowing the inner cavities of adjacent cabinets 1 to communicate through this closed space. This design not only helps reduce exposed cables, thereby improving safety, but also greatly improves the convenience of power distribution. In addition, this embodiment uses baffle 6, baffle 7, and support plate 8 to restrict the fixing plate 3 to remain parallel or perpendicular to the front of the cabinet 1, thus meeting the usage requirements of the fixing plate 3.
