Description

Technical Field

[0001] This utility model belongs to the field of smart distribution network technology, and in particular relates to a compatible DTU station terminal cabinet. Background Technology

[0002] Currently, DTUs (Dual Units) are typically installed in conventional switching stations, outdoor small switching stations, ring main units, small substations, and prefabricated substations. They collect and calculate data such as the position signals, voltage, current, active power, reactive power, power factor, and electrical energy of the switching equipment. They also perform opening and closing operations on the switches, enabling fault identification and isolation of feeder switches and restoration of power to non-faulty sections. However, existing DTU enclosures cannot provide a single enclosure that can accommodate different product installation modes and different power supply kits and capacitor banks. Utility Model Content

The cabinet body is a rectangular hollow structure. An outer door is installed on the front side of the cabinet body, an inner door is installed inside the outer door, and a rear door is installed on the rear side of the cabinet body. Module mounting plate assemblies are installed on the rear wall and left and right sides inside the cabinet body. The module mounting plate assemblies are installed into the cabinet body via continuous uprights. The module mounting plate assemblies on the rear wall inside the cabinet body are used to house a common unit, a switch module, and a power module arranged sequentially from top to bottom.

[0031] like Figures 1 to 8 As shown, a compatible DTU station terminal cabinet includes a cabinet body 1, an outer door 2, an inner door 3, a folder 4, a grounding copper busbar 5, a support frame 6, a rear door 7, a common unit mounting plate 8, a switch mounting plate 9, a power supply mounting plate 10, a battery pack and capacitor box 11, a common unit 12, a switch module 13, a power supply module 14, a dehumidifier 15, a fixing beam 16, an aviation plug mounting plate 17, a battery capacitor mounting plate, an aviation plug plate 18, and an independent logo plate 19. This compatible DTU station terminal cabinet is equipped with modular mounting plate components, which can be used for different types of product installation modes and can be equipped with different power supply packs and capacitor boxes. Its cabinet not only provides ventilation and heat dissipation, but also has dustproof and waterproof functions. Its outer door also has a glass window for easy real-time monitoring of the working status. Its rear door also has two cable entry holes to cooperate with the on-site vertical cable tray, which is aesthetically pleasing and convenient for cable entry and exit.

[0032] The shielded vertical combined capacitor DTU cabinet and most of its internal components are made of galvanized sheet with powder coating. In addition, a grounding copper busbar 5 is installed at the bottom of the cabinet 1. The grounding copper busbar 5 is made of metal copper, and the screws, washers and other fasteners are all made of stainless steel.

[0033] In a preferred embodiment of this utility model, the glass window of the outer door 2 is made of fiberglass, and a metal frame is welded to the inside of the outer door 2 to ensure proper installation of the glass window. The front of the cabinet 1 is the outer door 2, which has a glass window. The door lock and internal waterproof foam effectively prevent rainwater and dust from entering. Ventilation holes are provided on the upper left and right sides of the cabinet 1, and dustproof mesh is welded inside the ventilation holes to prevent larger dust particles from entering the cabinet while providing ventilation and heat dissipation. Handles are provided in the middle of the left and right sides of the cabinet 1, and variable cable outlet holes are reserved at the bottom to accommodate different cable outlet methods. When the side cable outlet holes are not used, the movable plate can be kept closed. Inside the cabinet 1, on both the left and right sides, are welded continuous uprights with modular holes. The top can accommodate various modular mounting plates of different sizes (including, from top to bottom, a common unit mounting plate 8, a switch mounting plate 9, a power supply mounting plate 10, an aviation plug mounting plate 17, and a battery / capacitor mounting plate), allowing for different module combinations. Depending on the module's position, load-bearing beams are welded inside the cabinet 1 to ensure secure installation. Below the modular uprights, an adjustable inner door 3 is installed. A folder 4 is installed on the back of the inner door 3 for storing paper documents. Opening the inner door 3 reveals studs welded to the bottom of the cabinet 1, accommodating different battery packs and capacitor banks 11 (thus matching different power supply modes). Depending on the actual situation, aviation plug mounting plates 17 can be welded to the inner sides of the cabinet 1. Aviation plug plates 18 are mounted on these plates, and their positions are adjustable. A dehumidifier 15 can be mounted on a guide rail, which is fixed to a suitable position on the aviation plug mounting plate 17. A rear door 7 is installed at the rear of cabinet 1. A positioning pin is welded to the bottom of the rear door 7 panel. Holes are drilled at the corresponding positions on cabinet 1 for proper installation. Door locks are installed on the upper left and right sides of the rear to ensure proper installation of the rear door 7. The rear door 7 is equipped with two cable entry holes to accommodate the on-site vertical cable trays, which is aesthetically pleasing and convenient for cable entry and exit. The support frame 6 and the fixed beam 16 are used to support and fix the common unit 12, the switch module 13 and the power module 14. The independent logo plate 19 is installed on one side of the bottom of cabinet 1. Its purpose is to allow for customization of different names and silkscreen printing, eliminating the need to purchase a separate DTU cabinet and reducing production costs.
