KYN28A-12(24) Armored Center-mounted AC Metal-enclosed Switchgear
The KYN28A-12 indoor armored center-mounted AC metal-enclosed switchgear (hereinafter referred to as the “center-mounted cabinet”) is a complete set of distribution equipment for 3–10 kV three-phase AC systems at 50 Hz, configured as either a single-bus or a single-bus sectionalized system. It is primarily used in power plants, for power delivery from small and medium-sized generators, for distribution in industrial and mining enterprises and other institutions, as well as for receiving and delivering power at secondary substations in the electric utility system and for starting large high-voltage motors. The cabinet is designed to provide control, protection, and monitoring functions. It complies with standards such as IEC 298 and GB 3906, and can be equipped with vacuum circuit breakers manufactured by Tian’an Electric, including models VT19 and VS1, as well as with vacuum circuit breakers from various domestic and international manufacturers, such as VD4, VB2, 3AE, and HVX.
1) Vacuum arc extinction and air insulation are employed;
2) The rated current can reach 4,000 A, and the short-circuit breaking current can reach 50 kA;
3) The product can be wall-mounted and maintained from the front of the cabinet, thereby reducing the footprint.
4) The main switch can be equipped with Tianan VT19 solid-insulated pole circuit breakers, VS1 circuit breakers, as well as other high-performance circuit breakers such as VD4 and VEP.
5) Overhead or cable incoming and outgoing lines may be used;
6) The cable compartment provides ample space for installing up to nine single-core cables;
