Description

Technical Field

[0001] This application relates to the field of gas ring main units, and more particularly to a compact and environmentally friendly gas ring main unit. Background Technology

[0002] In urban power grids and industrial park power distribution systems, gas-fired ring main units are key power distribution equipment that ensures power transmission and line switching control, and have a wide range of applications.

[0003] Currently, traditional gas-insulated ring main units (RMS) have loosely arranged internal components, resulting in a large overall size and occupying significant installation space. With increasingly compact spaces in urban power distribution rooms, underground utility tunnels, and small power distribution rooms, large RMS units not only restrict site selection and installation but also increase site planning and infrastructure costs. Furthermore, some older RMS models have poor sealing performance, leading to easy leakage of internal insulating gas, which wastes resources and impacts the surrounding environment, resulting in insufficient environmental performance. Therefore, we propose a compact, environmentally friendly gas-insulated RMS to address these issues. Utility Model Content

[0014] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0015] Please see Figure 1-4 In this utility model, a compact environmentally friendly gas ring main unit includes a cabinet 1. The front of the cabinet 1 is equipped with a protective component 4, a display component 2, and a control component 3. The interior of the cabinet 1 is provided with a mechanism compartment 5, a switch gas compartment 6, and a cable compartment 7. The cabinet 1 adopts a compact modular sheet metal frame structure, which is small in size, strong in rigidity, and has a highly optimized layout, greatly reducing the floor space. It is particularly suitable for narrow spaces such as urban power distribution rooms and underground pipe corridors. The DTU is integrated and placed on the top of the cabinet 1, further saving the outdoor cabinet space and realizing miniaturized and intensive installation.

[0016] Display component 2 includes a short circuit and ground fault indicator 8 and a high voltage live indicator 9. Both the short circuit and ground fault indicator 8 and the high voltage live indicator 9 are located on the front of the cabinet 1. Display component 2 consists of the short circuit and ground fault indicator 8 and the high voltage live indicator 9. The high voltage live indicator 9 is used to monitor the high voltage live status of the cable compartment 7 in real time, intuitively display whether it is live, and provide clear safety prompts for operators. The short circuit and ground fault indicator 8 can quickly indicate the line fault point, which is convenient for quick troubleshooting and maintenance.

[0017] The control component 3 includes a pressure gauge 10 and an electromagnetic lock 11. Both the pressure gauge 10 and the electromagnetic lock 11 are located on the front of the cabinet 1. The control component 3 consists of the pressure gauge 10 and the electromagnetic lock 11. The pressure gauge 10 monitors the pressure of the insulating gas inside the switch chamber 6 in real time to ensure that the sealing and insulation are normal. The electromagnetic lock 11 works with the isolation mechanism to achieve high-voltage interlocking. When the cable compartment 7 is energized, the cabinet door is automatically locked to prevent personnel from accidentally entering the energized compartment, thus ensuring personal safety from a structural perspective.

[0018] The mechanism compartment 5 includes a secondary compartment 14, which is located on the front of the cabinet 1. The secondary compartment 14 is equipped with a circuit breaker sealing mechanism 15 and an isolation sealing mechanism 16. The mechanism compartment 5 is a mechanism installation compartment. The secondary compartments 14 are centrally arranged above the mechanism compartment of the cabinet 1. The layout is compact and the space utilization is extremely high. The internal circuit breaker sealing mechanism 15 and isolation sealing mechanism 16 are equipped. The fully sealed structure can effectively prevent moisture, dust and corrosion, prevent the transmission mechanism from rusting and jamming, and significantly extend the service life of the cabinet 1.

[0019] The switch chamber 6 is located inside the cabinet 1. The switch chamber 6 is equipped with an expansion bushing 19, a fully enclosed circuit breaker switch 17, and an outgoing bushing 18. The switch chamber 6 is an environmentally friendly gas-insulated sealed chamber with a fully enclosed and compact layout. It houses the fully enclosed circuit breaker switch 17, the outgoing bushing 18, and the expansion bushing 19. The chamber has strong sealing performance, good insulation performance, no gas leakage, is environmentally friendly and safe, and has a small overall size, further improving the compactness of the cabinet 1.

[0020] The cable compartment 7 is located inside the cabinet 1, below the switch chamber 6. The cable compartment 7 is a high-voltage compartment, arranged below the switch chamber 6. The space is regular and convenient for cable wiring and maintenance. It is electrically and mechanically interlocked with the high-voltage live indicator 9 and the isolation sealing mechanism 16. It automatically locks when energized, strictly prohibiting opening the door and completely eliminating the safety risk of personnel accidentally entering the live compartment.

[0021] The protective component 4 includes a protective plate 13, which is located on the front of the cabinet 1. A heat dissipation window 12 is provided on the front of the protective plate 13. The protective component 4 consists of the protective plate 13 and the heat dissipation window 12. The protective plate 13 has dustproof, waterproof and accidental contact prevention functions to protect the internal instruments and mechanisms. The heat dissipation window 12 realizes natural heat dissipation, keeps the temperature inside the cabinet stable, and improves the reliability of equipment operation.

[0022] The working principle of this application is: This compact, environmentally friendly gas ring main unit features a three-compartment layout: the mechanism compartment 5, the switch gas compartment 6, and the cable compartment 7 are arranged vertically, maximizing space utilization. Secondary compartments 14 are concentrated above the mechanism compartment, and the DTU is placed on top of the unit, minimizing floor space. During operation, a high-voltage live indicator 9 monitors the energized status of the cable compartment 7 in real time. If energized, the cable compartment 7 is immediately interlocked via an isolation sealing mechanism 16 and an electromagnetic lock 11, preventing accidental entry. The switch gas compartment 6 uses environmentally friendly gas insulation, ensuring reliable sealing, no leakage, and environmental safety. The circuit breaker sealing mechanism 15 and the isolation sealing mechanism 16 within the mechanism compartment 5 are fully enclosed to prevent moisture and corrosion, extending service life. A pressure gauge 10 monitors the gas compartment pressure in real time, and a fault indicator quickly indicates line abnormalities. The overall equipment is compact, safe, environmentally friendly, and stable, suitable for various confined power distribution spaces.
