Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, and specifically to a new type of quick-release modular power distribution cabinet. Background Technology

[0002] Currently, the distribution cabinets used in power systems, industrial plants, and building power distribution are mostly integrated fixed cabinet structures. Internal power distribution components are directly fixed to the cabinet interior wall via bolts and guide rails, which presents the following prominent drawbacks: Traditional distribution cabinets have components arranged in layers, with upper-layer components being significantly higher than the ground, requiring operators to climb ladders for maintenance and replacement; all components are individually locked, requiring numerous fasteners to be loosened individually for disassembly, making the process cumbersome and difficult for a single person to handle, posing significant safety hazards such as falls and electric shocks; furthermore, existing distribution cabinets lack independent standardized module installation units for circuit breakers, transformers, contactors, and relay protection devices. Components such as metering instruments are scattered, and the layout of components in different circuits is messy. When a circuit fails, multiple components need to be disassembled on-site for inspection one by one, making it impossible to directly replace the entire circuit unit. Emergency repairs are time-consuming, and the duration of power outages is difficult to control. Finally, conventional module brackets are fixed only by a single set of bolts or simple clips, requiring tools to unlock during disassembly. The clips are prone to deformation and jamming due to long-term vibration and heat. There is no automatic unlocking mechanism, and manual operation is arduous when replacing modules in batches. Based on this, the present invention proposes a new type of modular distribution cabinet that can realize the rapid disassembly and assembly of distribution modules, automatically complete the removal and transportation of modules at high positions, and eliminate the need for bolts and other connecting parts for fixed installation. Summary of the Invention

[0003] To address the aforementioned technical issues, this invention prefabricates and integrates power distribution modules such as main circuit protection, metering, relay control, reactive power compensation, and signal monitoring into an independent module installation cabinet, allowing for rapid disassembly and replacement of the entire unit; it can replace manual high-altitude operations and eliminate safety hazards.

[0004] The technical solution used in this invention is as follows: a quick-release modular new type of power distribution cabinet, including a cabinet body, with several module chambers evenly distributed on both sides inside the cabinet body, and a transfer chamber in the middle of the inner side; module installation cabinets for installing each power distribution module are installed in the module chambers; each module chamber has a fastening mechanism at its inner end, and a fixing seat is fixed at the end of the module installation cabinet, with a mating hole on the fixing seat and a fastening seat fixed at the top, the fastening seat being fixed by the fastening mechanism; a disassembly and movement mechanism is slidably arranged in the transfer chamber for assisting in the disassembly and transfer of each module installation cabinet; including a vertically slidable slide block two, a horizontally slidable slide block three on the slide block two, a mating shaft and a push table telescopically arranged on the slide block three, the push table having a partially spherical structure; the mating shaft can mate with the mating hole, and the push table can control the fastening state of the fastening mechanism; a support mechanism is provided at the top of the cabinet body for supporting the transfer of each module installation cabinet.

[0005] The modular installation cabinet is an independent, enclosed, standardized unit compartment. Internally, different power distribution modules are integrated according to power distribution function zones. Each module is pre-wired and tested for withstand voltage before being fully encapsulated, enabling immediate use upon installation. The internal power distribution modules are categorized as follows: Main circuit protection module: integrates molded case circuit breaker, disconnector, and zero-sequence current transformer as a single-circuit total protection, suitable for power loads and high-power outgoing circuits; the module has a built-in arc-extinguishing baffle to isolate the arc when interrupting short-circuit current and avoid interference from adjacent circuits.

[0006] Metering and data acquisition module: integrates a multi-functional energy meter, voltage / current sampling terminals, and a communication data acquisition device for electricity consumption metering and remote power data uploading. The module has a reserved 485 communication interface, which can be connected to the background power monitoring system.

[0007] Control relay module: integrates intermediate relays, AC contactors, thermal overload protectors, and signal indicator lights, used for start-stop logic control of equipment such as motors, fans, and water pumps. It is internally divided into high-voltage and low-voltage signal areas, and the wiring is separated to prevent interference.

[0008] Low-voltage compensation module: integrates low-voltage parallel capacitors, reactors, and switching devices for reactive power compensation. The module has a built-in temperature sensor and a pressure relief and explosion-proof structure to prevent capacitor overheating and bulging.

[0009] Signal monitoring module: integrates temperature and humidity sensor, bus voltage acquisition module and fault alarm unit, collects cabinet temperature, loop current and bus voltage in real time, and uploads alarm signal to control module on the side of cabinet when fault occurs.

[0010] Each power distribution module achieves circuit connection through quick plug-in terminals. The back of the module installation cabinet is uniformly equipped with plug-in copper busbar interfaces. After being pushed into the module compartment, the main circuit conductive connection is automatically completed, eliminating the need for manual on-site wiring. The power distribution modules with different functions have uniform dimensions and can be arbitrarily interchanged and assembled into any module compartment, adapting to different power distribution schemes and making flexible adjustments.

[0011] Furthermore, the top of the cabinet is provided with an air intake box, which is connected to two heat dissipation ducts that penetrate the interior of each module. The heat dissipation ducts have air holes in their circumferential areas and air outlets starting from the bottom of the heat dissipation ducts.

[0012] Furthermore, the transfer chamber has horizontally arranged transfer slots on both sides, which allow the disassembly and movement mechanism to move each module installation cabinet laterally.

[0013] Furthermore, the support mechanism includes a guide rod, a lead screw, and a motor mounted on the cabinet. The motor is fixed to the top of the cabinet, the guide rod is fixed to the back of the cabinet, and the lead screw is rotatably mounted on the back of the cabinet. The lead screw is driven by the motor. A lifting platform is slidably fitted on the guide rod. The lifting platform and the lead screw form a helical pair. Positioning cylinders are fixedly installed at both ends of the lifting platform. An L-shaped support platform is fixed on the telescopic rod of the positioning cylinder. The support platform is provided with a positioning groove.

[0014] Furthermore, the dismantling and moving mechanism includes a motor two fixed to the top of the cabinet, a guide rod two fixed inside the transfer chamber, and a lead screw two rotatably mounted thereon. The lead screw two is driven by the motor two, and a slide block two is slidably engaged with the guide rod two, forming a helical pair with the lead screw two. A motor three and a guide rod three are fixed on the slide block two, and a lead screw three is rotatably mounted thereon. The lead screw three is driven by the motor three, and the slide block three is slidably engaged with the guide rod three, forming a helical pair with the lead screw three.

[0015] Furthermore, a matching electric cylinder is fixed on the slide block three, and the matching shaft and push table are fixed on the telescopic rod of the matching electric cylinder. The matching shaft and push table are arranged horizontally.

[0016] Furthermore, the fastening mechanism includes a fastening platform slidably mounted on the inner side of the module, and a spring for providing a reset elastic force is connected between the fastening platform and the bottom end of the inner side of the module; a ball-head push rod is fixed at the bottom end of the fastening platform, and the ball-head push rod can be pushed by a pusher to make the fastening platform move up and down.

[0017] Furthermore, a snap plate is telescopically provided at the end of the snap-fit ​​platform, and a second spring for providing a reset elastic force is connected between the snap plate and the snap-fit ​​platform. The snap plate is fastened to the snap seat to fix the module mounting cabinet.

[0018] The beneficial effects of this invention compared with the prior art are: (1) This invention can automatically complete the unlocking, extraction, and lowering of the high-altitude module without the need for manual climbing of ladders; the heavy reactive power compensation and main protection power distribution module can be transferred smoothly as a whole, eliminating safety accidents such as falling from heights, collisions with heavy objects, and electric shocks. A single person can complete all disassembly and assembly operations, greatly reducing the intensity of manual labor; (2) The spherical push table combined with the double spring reset buckling structure is used, and the electric cylinder drives automatic unlocking without the need for auxiliary tools such as wrenches and screwdrivers; the double elastic reset of spring one and spring two can withstand long-term vibration and high temperature environments. It will not get stuck, and the unlocking action is smooth and stable; the shaft positioning structure ensures that the force is even when pushing and pulling the module; (3) The double through-type heat dissipation duct is paired with the top air box, and the airflow flows evenly through each module chamber. All power distribution modules are cooled at the same time, which solves the problem of overheating and aging of high-power components on the upper layer of the traditional cabinet; the air duct is fully covered without heat dissipation dead corners, which reduces the occurrence rate of short circuit and tripping faults and extends the service life of power distribution components; (4) The L-shaped support platform has positioning slides and vertical limit baffles. The module is pushed and pulled, and the lifting and transfer are fixed throughout the process, avoiding the built-in precision metering and relay power distribution modules from being bumped and damaged.
