Description

Technical Field

[0001] This utility model relates to the field of ring main units, and in particular to a fully enclosed ring main unit that can be remotely monitored. Background Technology

[0002] A ring main unit (RMB) is an electrical device specifically designed for power transmission and distribution systems. It typically consists of a set of high-performance electrical components housed in a robust metal or non-metal insulated cabinet. Furthermore, RMBs can be designed as modular, compartmentalized ring network power supply units for flexible configuration and expansion. RMBs play a crucial role in power systems, enabling not only efficient power transmission and distribution but also ensuring the stable operation and security of the power grid. Through RMBs, power systems can achieve ring network power supply, forming a closed loop network between multiple power supply points, thereby improving the reliability and flexibility of power supply.

[0003] In existing ring main units, there are many internal electrical devices that work together and operate independently without being affected by external environmental conditions, thus ensuring operational reliability and personal safety. However, the complex cabling between the electrical devices installed inside the ring main unit increases the difficulty of later maintenance and inspection.

[0004] To address these issues, a fully enclosed ring network cabinet capable of remote monitoring is proposed. Utility Model Content

The mechanism box is located above the cable compartment, and the air box is located beside the mechanism box and the cable compartment. The mechanism box, air box, and cable compartment located inside the cabinet body are independent of each other. A cabinet door is hinged to one side of the mechanism box, and a central controller is installed on the cabinet door. A sealing door panel is hinged to one side of the cable compartment.

[0008] The gas box is equipped with a connecting frame, on which electrical equipment is installed. The mechanism box is equipped with an energy storage detector and a measuring instrument that are electrically connected to the central controller. The energy storage detector and the measuring instrument are electrically connected to the electrical equipment and are used to detect the parameters of the electrical equipment inside the gas box.

[0009] As a preferred embodiment of this utility model, the mechanism box is provided with a load switch, the load switch is connected to a busbar, one end of the busbar is provided with a plug, and the cable compartment is provided with a socket corresponding to the plug.

[0010] As a preferred embodiment of this utility model, a circuit breaker is also installed on the connecting frame, and the circuit breaker is provided with an operating mechanism for controlling the closing of the circuit breaker, and the operating mechanism extends to the mechanism box.

[0011] As a preferred embodiment of this utility model, a plurality of external connection holes are provided on one side of the cabinet body, a plurality of connecting lines are provided on the mechanism box, and wire grooves are provided on both sides of the mechanism box inside the cabinet body, and the connecting lines are connected to the external connection holes through the wire grooves.

[0013] As a preferred embodiment of this utility model, the mechanism box is provided with a vent hole, and the sealing door panel is provided with a ventilation hole.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. By dividing the interior of the ring main unit into three independent areas—mechanism box, gas box, and cable compartment—the cable layout is effectively simplified. The cable compartment is mainly used to store the lines, the electrical equipment inside the gas box is centrally installed through a connecting frame, and the mechanism box is responsible for control and monitoring. Each area has a clear function and does not interfere with each other. Energy storage detectors and measuring instruments detect various parameters of the electrical equipment, and remote monitoring is achieved through the central controller, which greatly improves the convenience of maintenance and the safety of operation.

[0016] 2. When assembling the ring main unit, the wiring of the electrical equipment in the gas box is collected into the connecting line, introduced into the mechanism box through the wire groove, and guided to the external connection hole along the wire groove for easy assembly and installation.
