KYN28A-12 Armoured Removable AC Metal Switchgear, rated voltage 12kV, three-phase AC 50Hz single busbar.Indoor complete sets of power distribution units for segment systems or double busbar segmentation systems. It is used to receive and distribute 3.6-12kV network power, and to electricity.The circuit is controlled, protected, monitored, and measured. The mid-mounted switchgear is mainly used for power plants, power transmission of small and medium-sized generators, and power systems.The power receiving and transmission of the secondary substation, the power distribution of industrial and mining enterprises and institutions, and the starting of large high-voltage motors, etc., realize control,Functions for protection and detection.
The performance of this switchgear meets the requirements of GB3906, IEC298 and other standards.Prevent mis-closing of the circuit breaker, prevent the grounding switch from closing the circuit breaker when it is in the closing position, prevent it from entering the live compartment by mistake, and prevent the misconnection of the live space,The grounding switch is a power distribution device with superior performance.
