Permanent Magnet Ring Network cabinetsIs a group of transmission and transformation equipment installed in the cabinet or assembled into the spacer Ring Network power supply unit of electrical equipment, the use of load switch, fuse, simple structure, small size, improve the power supply parameters and performance, with the characteristics of power supply safety. All power distribution branches are equipped with outlet switchgear. The ring cabinet has a small rated current. The high voltage switch in the ring cabinet is generally a load switch. The normal current is controlled by the load switch and the short-circuit current is disconnected by the fuse. Together, the circuit breaker is replaced by a high-voltage switch in the ring cabinet.

Permanent Magnet Inflatable CabinetsIs the use of Permanent magnet mechanism and spring mechanism circuit breaker of the new generation of switchgear. The inflatable cabinet has compact structure and flexible operation. The different technical scenarios for the application scenario are different. Inflatable cabinets are suitable for applications where electricity is in high demand.

Ring cabinets are classified by purpose. Switch cabinets in the ring net. Most of these switchgear for the load switchgear and rated current is not less than 630A combination of electrical cabinets, belonging to two power distribution equipment. The inflatable cabinet is a switch cabinet with gas as the insulating medium. According to the application area can be divided into one power distribution equipment and two power distribution equipment. Because of its compact structure and small size, it is very small. Inflatable cabinets are used in all multi-ring network cabinets.

The design of the inflatable cabinet provides two options for transformer protection: Load switch-fuse combination and circuit breaker with relay protection. As the preferred ring mesh unit, the inflatable cabinet can provide a complete set of integrated remote control and monitoring units. Ring cabinet using load switch, SF6 or vacuum circuit breaker, grounding switch, transformer, two times components and other standardized devices. Through the combination of these standardized components, ring cabinets can be widely used in different situations.
