Description

A modular primary and secondary integrated ring network box Technical Field

[0001] This invention belongs to the field of primary and secondary integrated ring network cabinet technology, and specifically provides a modular primary and secondary integrated ring network box. Background Technology

[0002] In the planning and implementation of outdoor power distribution systems, to ensure that the entire power supply scheme fully meets the core requirements of safety, stability, and timeliness, the industry generally prefers to adopt a ring network power supply mode. This mode involves setting up a ring network cabinet station at reasonable intervals along the power supply line. Each such station deploys a primary and secondary integrated ring network cabinet, specifically designed to efficiently and reliably meet the low-voltage power needs of end users. The primary and secondary integrated ring network cabinet represents an emerging technological direction in the field of smart grid distribution. As an advanced intelligent power distribution device, it is currently widely used in the terminal links of urban power grids, playing a crucial role in improving the automation level and power supply quality of the power grid.

[0003] However, the current mainstream design of ring main units has certain limitations, with their form and structure being relatively fixed. Typically, the entire enclosure is assembled in the factory workshop and then transported to the site as a single unit for deployment. This integrated prefabrication model significantly increases the difficulty of transportation, resulting in high logistics costs. Furthermore, during on-site installation, its flexibility in adapting to specific environmental conditions is poor, making it difficult to easily adjust according to site space and cable routing. In addition, anti-condensation mechanisms designed to address potential moisture issues inside the enclosure are usually pre-installed within the ring main unit's interior. This pre-installation method, to some extent, occupies valuable internal layout space, affecting the arrangement of other electrical equipment or cables, thus reducing the overall utilization efficiency of the ring main unit's internal space. Simultaneously, the current design of the ring main unit's top cover often has a relatively simple structure and function, primarily serving only basic protection and shielding purposes. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a modular primary and secondary integrated ring network box, including a high-voltage cabinet, a gas-liquid circulation cabinet, a low-voltage cabinet, a temperature control module, and a top cover. The temperature control module is assembled on the back side of the high-voltage cabinet. After the gas-liquid circulation cabinet and the low-voltage cabinet are spliced ​​together, they are combined with multiple high-voltage cabinets by bolts to form a cabinet body. The top cover is fixedly installed on the top of the cabinet body. The high-voltage cabinet is composed of a cabinet frame and wall panels. The wall panels are assembled to the cabinet frame by screws. The bottom layer of the cabinet frame is a bottom chamber, and pipelines are pre-installed in the bottom chamber. A rear assembly seat is provided at the rear end of the cabinet frame. The temperature control module is assembled at the rear assembly seat. The surface of the rear assembly seat is provided with pipeline interfaces. The temperature control module is connected to the pipeline interfaces. A transverse partition is assembled inside the high-voltage cabinet.

[0005] Furthermore, the diaphragm is composed of a plate, an elastic tension member, and a connecting cable. The bottom of the multiple plates is provided with a groove and a guide sleeve in the horizontal direction. The connecting cable is embedded in the groove and passes through the guide sleeve. The multiple plates are connected in series by the connecting cable. Both ends of the connecting cable are provided with an elastic tension member, which is fixedly connected to the bottom surface of the plate.

[0006] Furthermore, multiple strip-shaped holes are provided at the edge of the plate, and corner brackets are provided at the bottom of the multiple plates, which are assembled to the strip-shaped holes by screws.

[0007] Furthermore, the bottom surface of the bracket is provided with a leaf vein skeleton.

[0008] Furthermore, a bracket is provided at the bottom of the high-voltage cabinet cavity, and a sliding base is slidably installed above the bracket; the bracket is trapezoidal, and both ends of the bracket are upturned to form triangular grooves, and multiple rollers are rotatably installed on the surface of the bracket; the side wall of the sliding base is rolled inward to form a triangular support, and multiple balls are evenly embedded on the inclined side wall of the triangular support.

[0009] Furthermore, the rear end of the sliding chassis is provided with a claw connecting hook, and the rear side wall of the high-voltage cabinet cavity is provided with a claw. When the sliding chassis moves to the rear end, the claw engages with the claw connecting hook.

[0010] Furthermore, the claw is assembled to the side wall of the high-voltage switchgear via an elastic connector. A screw is screwed to the side wall of the high-voltage switchgear, and a lever is provided at the end of the screw. A strip groove is provided at the top of the claw, and the lever engages with the strip groove.

[0011] Furthermore, the temperature control module includes an outer cover plate, a heat pipe, a condenser plate, a connecting plate, a flame-retardant heat insulation layer, and an insulation layer. The flame-retardant heat insulation layer and the insulation layer are encapsulated on one side of the connecting plate, and the condenser plate is assembled on the other side of the connecting plate. The heat pipe is fixedly installed on the condenser plate, and a gap is left between the heat pipe and the condenser plate. The outer cover plate wraps around the heat pipe, the condenser plate, the connecting plate, the flame-retardant heat insulation layer, and the insulation layer, and a drain outlet is provided at the bottom of the outer cover plate. The cross-section of the condenser plate is wavy, and the bottom end of the condenser plate is bent backward to form a guide section. The guide section is distributed at an obtuse angle with the main body of the condenser plate.

[0012] Furthermore, an assembly groove is provided on the inner wall of the top cover, and an arch plate is installed inside the top cover through the assembly groove. Multiple filter media slots are provided on the bottom surface of the arch plate, and an air guide pipe is provided on the top of the arch plate. The air guide pipe connects the multiple filter media slots, and filter media is installed in the filter media slots.

[0013] Furthermore, the filter material consists of a shell and a filter element. The top surface of the shell is evenly provided with multiple filter material exhaust ports, and the bottom of the shell is provided with a unidirectional filter material air inlet. The top surface of the shell is also provided with a sealing ring. When the filter material is embedded in the assembly groove, the gap between the inner wall of the assembly groove and the filter material and the sealing ring form a sealed air guiding channel. Each assembly groove is provided with two vent holes, and both vent holes are connected to the air guiding pipe.

[0014] The beneficial effects of using this invention are as follows: The invention adopts a modular design as a whole. The high-pressure cabinet, gas-liquid circulation cabinet, low-pressure cabinet, temperature control module and top cover can all be independently packaged. The high-pressure cabinet can be further disassembled. During transportation, each cabinet unit, wall panel, top cover and other components can be disassembled and transported independently, which reduces the occupancy rate of transportation space and reduces the difficulty and cost of logistics transportation. After arriving at the site, the splicing and combination of each unit can be flexibly adjusted according to the actual space and route of the site, making it more adaptable.

[0015] The temperature control module is integrated on the back side of the high-voltage cabinet, without occupying the internal layout space of the cabinet. It can work with the pre-laid pipelines in the bottom chamber to complete the temperature control, dehumidification and anti-condensation operations, which greatly improves the space utilization rate inside the cabinet.

[0016] The bottom of the high-voltage cabinet is equipped with a sliding base that can be pulled out. During maintenance, the core components pre-installed on the base can be pulled out of the cabinet as a whole, making it convenient for maintenance personnel to operate. After sliding into place, the base can be locked by the claws and claw connecting hooks to prevent the sliding base from accidentally sliding into the cabinet during maintenance, thus improving the safety of maintenance operations.

[0017] The corrugated condenser plate of the temperature control module can increase the contact area with humid air, more efficiently guiding the water droplets condensed in the air downwards, and finally draining them out from the drain outlet at the bottom of the outer panel along the guide section, preventing condensation droplets from dripping onto the components inside the cabinet and improving the dehumidification and anti-condensation effect.

[0018] The top cover has an integrated filter structure that can filter out moisture and dust from the air while ensuring normal internal and external air circulation. It also reduces the probability of condensation inside the cabinet while maintaining internal air pressure balance. The overall structure is reasonably designed, with high space utilization, and is convenient for transportation, installation and maintenance. Attached Figure Description

The temperature control module 4 is mounted on the back side of the high-voltage cabinet 1. After the gas-liquid circulation cabinet 2 and the low-voltage cabinet 3 are spliced ​​together, they are combined with multiple high-voltage cabinets 1 by bolts to form a cabinet body. The top cover 5 is fixedly installed on the top of the cabinet body. The high-voltage cabinet 1 is composed of a cabinet frame 101 and wall panels 106. The wall panels 106 are mounted on the cabinet frame 101 by screws. The bottom layer of the cabinet frame 101 is a bottom chamber, in which pipelines are pre-installed. A rear mounting seat 105 is provided at the rear end of the cabinet frame 101. The temperature control module 4 is mounted at the rear mounting seat 105. The surface of the rear mounting seat 105 is provided with pipeline interfaces. The temperature control module 4 is connected to the pipeline interfaces. A transverse partition 102 is installed inside the high-voltage cabinet 1.

[0022] When a large cabinet with interconnected internal spaces is required, the side wall panels 106 of the high-voltage cabinet 1 located in the middle are removed to open up the internal spaces of multiple high-voltage cabinets 1.
