Description

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 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 high-voltage cabinet is equipped with a temperature control module on the back side. 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.

[0005] The high-voltage cabinet consists of a cabinet frame and wall panels. The wall panels are assembled onto the cabinet frame with screws. The bottom layer of the cabinet frame is a bottom chamber, in which pipelines are pre-installed. A rear mounting base is provided at the rear end of the cabinet frame, and the temperature control module is assembled at the rear mounting base. The surface of the rear mounting base is provided with pipeline interfaces, and the temperature control module is connected to the pipeline interfaces. The interior of the high-voltage cabinet is equipped with a partition plate.

[0006] 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.

[0007] 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.

[0008] Furthermore, the bottom surface of the bracket is provided with a leaf vein skeleton.

[0009] Furthermore, a bracket is provided at the bottom of the inner cavity of the high-voltage cabinet, and a sliding base is slidably installed above the bracket;

[0010] The bracket is trapezoidal, with both ends curving upwards to form triangular grooves, and multiple rollers are rotatably mounted on the surface of the bracket.

[0011] The sidewalls of the sliding chassis are rolled inward to form a triangular support, and multiple balls are evenly embedded in the inclined sidewalls of the triangular support.

[0012] 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.

[0013] 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.

[0014] 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, 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.

[0015] The condenser plate has a wavy cross-section, and the bottom end of the condenser plate bends backward to form a guide section, which is distributed at an obtuse angle to the main body of the condenser plate.

[0016] 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.

[0017] Furthermore, the filter material is composed of a shell and a filter element. The top surface of the shell is evenly provided with multiple filter material exhaust ports, the bottom of the shell is provided with a unidirectional filter material air inlet, and 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.

[0018] Each of the assembly slots is provided with two vent holes, both of which are connected to the air guide pipe.

[0019] The beneficial effects of using this invention are:

[0020] The invention adopts a modular design. 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.

[0021] Upon arrival 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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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

[0070] The present invention will now be described in detail with reference to the accompanying drawings.

[0071] Reference Figures 1-4 A modular primary and secondary integrated ring network box includes a high-voltage cabinet 1, a gas-liquid circulation cabinet 2, a low-voltage cabinet 3, a temperature control module 4, and a top cover 5. The high-voltage cabinet 1 is equipped with a temperature control module 4 on its back side. 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.

[0072] The high-voltage cabinet 1 is composed of a cabinet frame 101 and a wall panel 106. The wall panel 106 is assembled onto the cabinet frame 101 with screws. The bottom layer of the cabinet frame 101 is a bottom chamber, in which pipelines are pre-installed. A rear mounting base 105 is provided at the rear end of the cabinet frame 101. The temperature control module 4 is assembled at the rear mounting base 105. The surface of the rear mounting base 105 is provided with pipeline interfaces. The temperature control module 4 is connected to the pipeline interfaces. A horizontal partition 102 is assembled inside the high-voltage cabinet 1.

[0073] 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.

[0074] Based on the project scale, estimate the size of the compressor equipment required for the low-voltage power supply area and temperature control module, and complete the skid installation of gas-liquid circulation cabinet 2 and low-pressure cabinet 3 in advance. During on-site deployment, the specifications of the ring network box can be adjusted within the rated working range of gas-liquid circulation cabinet 2 and low-pressure cabinet 3.

[0075] Preferably, the cabinet frame 101 is made of steel structure with plug-in connection, and is reinforced with accessories such as rivets, bolts and angle iron.

[0076] In addition, the high-voltage cabinet 1 in the example is a vertical long cabinet arranged horizontally. In actual production, different specifications of low-profile models can be produced according to requirements. The appearance is similar to that of the low-voltage cabinet 3. The deployment process can also adopt a vertical assembly scheme.

[0077] Reference Figure 10 and Figure 11 The diaphragm 102 is composed of a plate body, an elastic tension member 1022 and a connecting cable 1023. The bottom of the multiple plates is provided with a groove 1028 and a guide sleeve 1029. The connecting cable 1023 is embedded in the groove 1028 and passes through the guide sleeve 1029.

The elastic tension member 1022 is fixedly connected to the bottom surface of the plate body.

[0078] When multiple panels are folded and placed, the connecting cable 1023 pulls the elastic tension member 1022 to extend. When stacked or placed with other panels, the continuously applied external force keeps the multiple panels in a folded state.

[0079] When the external force is removed, the rebound force of the elastic tension member 1022 will pull multiple plates to unfold and reset to a flat state.

[0080] Multiple strip holes 1026 are provided at the edge of the plate, and corner brackets 1021 are provided at the bottom of the multiple plates. The corner brackets 1021 are assembled to the strip holes 1026 by screws.

The sliding pin 1085 slides backward and pulls the telescopic latch 1084 through the lasso 1086, releasing the locking state of the lower support 1082. The lower support 1082 hangs down under the action of gravity and disengages from the storage slot 1087. The operator slightly lifts the pull-out plate 1081 to rotate the lower support 1082 to the unfolded state, and then rotates the upper support 1083 to unfold. Then, the sliding base 104 is pulled out and placed on the upper support 1083.
