KYN28-24 Metal-claded withdrawable AC metal-enclosed switchgear is a complete set of power distribution equipment for 24kV three-phase AC 50Hz single bus and single bus section system. It is mainly used for power plants, small and medium generators to transmit power, power distribution of industrial and mining enterprises, and secondary substations of electrical industry systems for control, protection, and monitoring. This switchgear meets DL/T404, IEC298, GB3906 and other standards. It has the interlock function to prevent the load-carrying withdraw circuit breaker trolley, prevent the circuit breaker from being closed or opened by mistake, to prevent the circuit breaker from being closed when the earth switch is in the closing position, to prevent entering the live compartment by mistake, and to prevent the earth switch from being closed by mistake.
