2. Technical Features

▪ High voltage live parts are gas insulated and are not affected by the environment

▪ Compact structure and small footprint

▪ Adopt interface insulation structure, realize the plug-in of high-voltage components and the expansion of the cabinet

▪ Effective interlocking is used between the circuit breaker and the isolating switch to prevent misoperation

▪ High voltage components are composed of several standard modules, which are connected by plug-in type and are easy to use.

▪ Solid insulated busbars are used to connect the switch cabinets, and no gas operation is involved when assembling the switch cabinets.

▪ All main primary components are sealed in a non-magnetic stainless steel welded air chamber, avoids electromagnetic eddy current and is not affected by the external environment.

▪ The air box is filled with micro-pressure gas with excellent insulation and thermal conductivity.SF6 gas, more reliable operation.

▪ The air box adopts integrated design and manufacturingThe key static seal structure adopts multiple seals with large sealing surfaces, and the rotary dynamic seal adopts magnetic fluid seal, which has extremely low leakage rate.

▪ The product realizes modular designThe cabinets are connected by plug-in insulated busbar connectors, which are easy to install, have complete solutions, and are flexible to expand. On-site cabinet connection does not involve gas operations.

▪ The product can be operated manually or electricallyThe operating mechanism is mature and reliable, and has complete mechanical and electrical interlocks that can effectively prevent personal injury and equipment damage that may be caused by misoperation.

▪ Compact product designCompared with traditional air-insulated switchgear, the volume is significantly reduced, and the floor space is saved by 30% to 70%. It is particularly suitable for occasions with limited space, such as underground rail transit, vehicle-mounted mobile substations, etc., and can effectively reduce the overall cost of the project.

▪ Microprocessor-based protection and system technology, which integrates protection, control, measurement, monitoring and communication functions, realizes comprehensive automation requirements and can be completely unmanned.
