Ring Main Unit is a set of electrical transmission and distribution equipment (high-voltage switching equipment) installed in a metal or non-metal insulated cabinet, or an electrical equipment made into an assembled and partitioned ring network power supply unit.
It is suitable for three-phase AC rated voltage 12KV, rated frequency 50Hz power system, used to accept and distribute power and implement control, protection, wireless temperature measurement and online monitoring device for the circuit.
The core part of SF6 ring network cabinet adopts load switch, fuse and circuit breaker, which has the advantages of simple structure, small volume, low price, and can improve the parameters and performance of power supply as well as the safety of power supply.
1250A SF6 inflatable cabinet with its core part using load switch, circuit breaker, has the advantages of simple structure, small volume, low price, can improve the power supply parameters and performance as well as power supply safety.
Environmental protection gas ring network cabinet adopts dry air or N2 as insulation medium, vacuum arc extinguishing chamber to extinguish the arc, and its disconnecting switch and arc extinguishing chamber are fully sealed in the stainless steel gas box of dry air or N2.
ZW20-12 outdoor high-voltage vacuum circuit breaker is an outdoor distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. Vacuum arc extinguishing and SF6 gas are used as insulation media. It is mainly used to disconnect and close the load current, overload current, and short-circuit current of rural power grids, urban power grids, and small power systems.
Outdoor high-voltage drop out fuse is the most commonly used short-circuit protection switch for 10kV distribution line branch lines and distribution transformers. It has the characteristics of economy, easy operation, and strong adaptability to outdoor environments. It is widely used in 10kV distribution lines and primary side of distribution transformers for protection and equipment switching operations.
XGW-12 series of primary and secondary fusion standardised ring network box (open and close house) adopts HTN-12 environmentally friendly gas ring network cabinet switchgear,which has the advantages of modularity, scalability, full insulation, full sealing, safety and reliability, maintenance- free,wireless temperature measurement, online monitoring device, etc. It is suitable for any harsh environment, and is widely used in industrial parks, residential areas, streets, airports, all kinds of buildings,bustling commercial centres and other places.
ZW32 outdoor column mounted vacuum circuit breaker is an outdoor high-voltage distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. Mainly used for breaking and closing load currents in power systems. Suitable for protection and control in power distribution systems of substations and industrial and mining enterprises, and more suitable for urban and rural power grid construction and renovation, as well as frequent operation sites.
The primary and secondary fuses (ordinary pole type) integrate industry-leading electromagnetic voltage transformers and electromagnetic current transformers, combined with electromagnetic automation feeder terminals, with remote control, telemetry, remote signaling, and fault detection functions, and communicate with the distribution automation main station to provide information on the operation status and various parameters of the distribution system,as well as monitoring requirements such as switch status, energy parameters
