Technical Field
[0001] This utility model relates to the field of power distribution cabinets, and in particular to a multi-layer splicing power distribution cabinet. Background Technology
[0002] Distribution cabinets are important equipment in power systems used for centralized control and distribution of electrical energy. They are widely used in industrial, commercial, and residential buildings. Their main function is to introduce high-voltage power from the power source and distribute it to various electrical devices, while protecting the circuit from overload, short circuit, and other faults. Distribution cabinets consist of a metal casing, circuit breakers, switching equipment, measuring instruments, and controllers. They are equipped with multiple circuit switches inside, which can distribute current according to load requirements and prevent electrical faults through protection devices.
[0003] Distribution cabinets can be classified into low-voltage, medium-voltage, and high-voltage distribution cabinets based on their usage environment and requirements. Each type of distribution cabinet differs in structure and function. Low-voltage distribution cabinets are typically used in residential and small industrial environments, while medium-voltage and high-voltage distribution cabinets are mostly used in large industrial equipment, power substations, and urban power systems. In addition, modern distribution cabinets also have intelligent functions, which monitor the operating status of electrical equipment in real time through monitoring systems, thereby improving the efficiency and safety of power management. In general, distribution cabinets are a crucial component of the power system, ensuring the rational distribution of electrical energy and the safety of electricity use, and guaranteeing the reliability and stability of power supply.
[0004] However, traditional power distribution cabinets are all one-piece molded. When a module needs to be added to a certain device, the existing power distribution cabinet is already full or the remaining size is too small to install the new module. In this case, a new power distribution cabinet must be installed next to it, which not only wastes space but also increases costs. Therefore, a multi-layer splicing power distribution cabinet is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a multi-layer splicing power distribution cabinet, which aims to improve the problem that traditional power distribution cabinets are all integrally molded. When it is necessary to add a module to a certain device, the previous power distribution cabinet is already full or the remaining size is too small to install the new module. It is necessary to install a new power distribution cabinet next to it, which not only wastes space but also increases costs.

[0010] As a further description of the above technical solution:
[0011] The sliding plate is externally slidably connected to the inner wall of the outer casing, and the plug is externally inserted into the extension cabinet or top cabinet.
[0012] As a further description of the above technical solution:
[0013] The rear side of the baffle is slidably connected to the front side of the limiting plate, and the front side of the baffle and the rear end of the insertion rod abut against each other.
[0014] As a further description of the above technical solution:
[0015] The bottom of the baffle and the top of the slide plate abut against each other, and a handle is fixedly connected to the front end of the plug rod.
[0016] As a further description of the above technical solution:
[0017] One end of the spring is fixedly connected to the inner wall of the outer casing, and the inner side of the spring is sleeved on the outside of the insert rod.

[0035] Reference Figure 1 , Figure 4 , Figure 5The dehumidification assembly includes a frame 10, an exhaust fan 12, and a housing 13. The frame 10 is externally slidably connected to the inner wall of the cabinet 1, and a moisture-absorbing gel 11 is slidably connected inside the frame 10.

[0036] Working principle: When installing components in the distribution cabinet, first pull the plug rod 5, which causes the slide plate 6 to compress the spring 7, causing the plug rod 5 to retract into the housing 4. At the same time, the baffle 8 will automatically fall into the housing 4, blocking the outlet of the plug rod 5. Then, insert the extension cabinet 2 into or remove it from the base cabinet 1. Then, under the limit of the limit plate 9, pull the baffle 8. At this time, the spring 7 will immediately push the slide plate 6 to reset, causing the plug rod 5 to be inserted into the extension cabinet 2, thus fixing the extension cabinet 2. Similarly, install the top cabinet 3 onto the extension cabinet 2. Then, install the components inside the extension cabinet 2 and the top cabinet 3. When using these components, by controlling the operation of the suction fan 12, the air outside the distribution cabinet will be drawn into the base cabinet 1 and filtered through the desiccant gel 11, removing the air inside. The moisture is removed and then blown into the extension cabinet 2 and top cabinet 3 to achieve dehumidification and avoid damage to components. At the same time, it provides ventilation and heat dissipation inside the distribution cabinet. After a period of use, the moisture-absorbing gel 11 will be saturated and needs to be replaced. By pulling the sleeve frame 10, the moisture-absorbing gel 11 is pulled out simultaneously, causing the ball bearing 16 to separate from the sleeve frame 10. Then, the moisture-absorbing gel 11 is removed and replaced with a new one. Then, the sleeve frame 10 is reinserted into the base cabinet 1. At first, the ball bearing 16 pushes the connecting block 15 to squeeze the second spring 14. When the sleeve frame 10 is fully inserted, the second spring 14 will instantly push the connecting block 15 to reset the ball bearing 16, which will then lock into the top of the sleeve frame 10, thus fixing the sleeve frame 10 and achieving replacement. The operation is convenient and labor-saving.
