High-Voltage Mid-Mounted Switchgear

KYN28-12 indoor AC metal armored removable switchgear is a complete set of power distribution devices for 3-10 kV three-phase AC 50Hz single bus and single bus segmentation system. Mainly used in power plants, small and medium-sized generator power transmission, industrial and mining enterprises and institutions power distribution and power system of the secondary substation of the power system, power transmission and large high-voltage motor starting, etc., for control protection, monitoring, this switchgear meets the requirements of DL/T404-91, IEC298, GB3906 and other standards, with the ability to prevent load push-pull circuit breaker handcart, to prevent misuse of the circuit breaker, to prevent the grounding switch from closing and breaking when in the closed position, to prevent accidental entry into the live compartment, To prevent the interlock function of the grounding switch from being misconnected when live, a variety of main switch configuration schemes are available: VS1, ZN21, VB5 (VB5P) VD4, VEP, 3AH. EV12 and VPR vacuum circuit breakers are actually a kind of power distribution devices with superior performance.
