The HXGNO-12 air-insulated ring main unit is an AC high-voltage switchgear with a rated voltage of 3.6 to 12kV and a rated frequency of 50Hz. It uses an AC high-voltage load switch with an insulated static contact cover and an AC high-voltage load switch-fuse combination device as the main switch. It is mainly used for three-phase AC ring networks, terminal distribution networks, and industrial electrical equipment, serving the functions of receiving and distributing electrical energy and protection.
Product Introduction:
The HXGNO-12 air-insulated ring main unit is an AC high-voltage switchgear with a rated voltage of 3.6 to 12kV and a rated frequency of 50Hz. It uses an AC high-voltage load switch with an insulated static contact cover and an AC high-voltage load switch-fuse combination device as the main switch. It is mainly used for three-phase AC ring networks, terminal distribution networks, and industrial electrical equipment, serving the functions of receiving and distributing electrical energy and protection.
Product Features:
The main switch adopts a load switch with an insulated static contact cover and a load switch-fuse combination device. The ring main unit is divided into busbar chamber, switch chamber, and instrument chamber, eliminating the need for related partitions and disconnecting plates. This design prevents arc short-circuit accidents inside the unit and ensures the personal safety of maintenance personnel when replacing fuses.
The main switch can be selected according to user requirements, with options for a compressed-air load switch or a vacuum load switch and its fuse combination device, while the external dimensions of the switchgear can remain basically unchanged.
The FN12-10 load switch adopts a compressed-air arc-extinguishing structure, with a rated breaking current of over 100 times and a maximum breaking current of 1800A, providing stable and reliable arc-extinguishing performance.
The vacuum load switch has a mechanical life of up to 10,000 operations, offering long service life and excellent performance, making it the preferred product for power systems.
The operating mechanism can be manual or electric, making it convenient to meet the requirements of the power system.
It is equipped with a complete electrical misoperation prevention device, meeting the "five protections" requirements.
