High pressure ring mesh cabinetsIs a set of high voltage switchgear installed in metal or non-metallic insulating cabinets or assembled into spacer ring network power supply units. Its core part uses load switch and fuse or vacuum circuit breaker and microcomputer protection device. It has the advantages of simple structure, small volume, low price, improved power supply parameters and performance, power supply safety and so on. Widely used in urban residential areas, high-rise buildings, large public buildings, factory enterprises and other load center distribution stations and box-type substations.

The role of high pressure ring cabinets:
1, it can enable users from two directions to obtain electricity, improve the reliability of power supply. It has the advantages of simple structure, small size and low price, which can improve the power supply parameters and performance and improve the safety of power supply. Therefore, it is widely used in distribution stations and box-type substations in urban residential areas, high-rise buildings, factory enterprises and other load centers.

2, connect the ring network line, improve the reliability of power supply, such as ring network line of the ring operation or load cut off.

High pressure ring cabinet type:
1, Vacuum ring cabinet: Vacuum ring cabinet is a new generation of environment-friendly solid insulated vacuum ring cabinet products. This product adopts vacuum circuit breaker + microcomputer protection device. All conductive circuits are coated with epoxy resin or silicone rubber, ensuring high safety in operation and operation. The maximum voltage can be up to 24,000 volts.

2, SF6 ring cabinet: SF6 Ring cabinet is a kind of medium voltage electrical equipment which can be arbitrarily combined into multiple circuits, with the function of switching, contact and protecting power system. Load switches are the core components of air insulation or gas insulation. Its main circuit core components are composed of auxiliary electrical appliances such as SF6 load switch or additional circuit breaker.

3, gas-producing ring cabinet: gas-producing ring cabinet is a solid gas production materials (such as plexiglass) made of arc extinguishing elements. When the current is cut off and closed, under the action of the arc, the material that produces the gas decomposes the gas so that the arc cools and extinguishes. The larger the splitting current, the stronger the arc, the more decomposition gas, the better the arc extinguishing effect.

4, Pneumatic ring cabinet: pneumatic ring cabinet because of its pneumatic load switch and named. The pneumatic switch uses compressed air to blow the arc and, when turned off, compresses the air in the cylinder through the rapid movement of the pneumatic piston. When the arc contact is separated to produce an arc, the compressed gas blows through the nozzle to the arc, so that the arc is elongated and extinguished at the current low point. The conversion current of the pneumatic load switch is about 1 kA, reaching the $ A short-circuit closed current. The thermal stable current is generally 20kA. A, 3 seconds.
