& Product Structural Features
. The structure is miniaturized, and the volume of the ring network cabinet is reduced by nearly % compared with the traditional vacuum circuit breaker, vacuum load switch, and combined electrical appliances, saving the overall investment in power engineering.
.The upper part of the switch cabinet includes the busbar room, instrument room, primary component room, and incoming and outgoing cable room.
.The switch cabinet is equipped with an isolating switch, a vacuum circuit breaker, and a grounding knife. The three are equipped with reliable interlocking. The isolating switch has an obvious break, and the switching status can be clearly observed.
The operating mechanism adopts a brand-new structure and uses forced mechanical locking to meet the "five prevention" functional requirements. It has the characteristics of easy operation, safety and reliability.
.The switch cabinet has a fully enclosed metal design and reliable grounding. There is a falsely sealed pressure relief port behind the top cabinet.
.The switch cabinet has an artificial intelligence voice operation prompt function to avoid malfunctions and accidents caused by human misoperation.
.The switch cabinet has a five-proof system to prevent misoperation to ensure the safety and reliability of equipment operation. Specifications and dimensions: Width*Depth*Height**/**/**/**
Air insulated ring network cabinets are generally called semi-insulated ring network cabinets Gas insulated ring network cabinets are generally called fully insulated ring network cabinets Cabinet
The difference is that
after inflatable insulation, the distance between phases is only that of air insulated cabinets, and the size of the switch cabinet is greatly reduced.
. Fully insulated ring main unit insulation medium: using gases such as , , and other gases or their composite gases as the insulation medium, with strong insulation performance.
. Electrical clearance: The insulation performance of insulating gas is much stronger than that of air. The electrical clearance of fully insulated cabinets is much smaller than that of semi-insulated cabinets
. Equipment size: Due to the small electrical clearance, the size of fully insulated cabinets is much smaller than that of the same voltage level. Semi-insulated cabinet, small footprint.
. Affected by altitude: The main circuit components of the fully insulated ring main unit are built into the inflatable compartment. The pressure is constant and is not affected by altitude. It is especially suitable for high altitude areas. The insulation performance of semi-insulated ring main unit is directly affected by altitude. Standard products are used in the following. Special designs are required for higher altitudes
. Impact of pollution: Pollution cannot affect the inflatable compartment of fully insulated ring main unit. It is suitable for pollution area. Semi-insulated ring network cabinets are directly affected by pollution, and particularly harsh conditions require special design
