Three-phase switchgear KYN61-40.5

ACmedium-voltageshort-circuit

KYN61-40.5 armored removable AC metal-enclosed switchgear is an indoor complete set of power distribution equipment with three-phase AC 50Hz and rated voltage 40.5kV. It is used for power plant, small and medium-sized generator power transmission, power distribution of industrial and mining enterprises, and secondary substations of power systems, power transmission, and large high-voltage motor starting, etc., for control, protection, and monitoring. It has the interlock function to prevent the push-pull circuit breaker handcart with load, prevent the circuit breaker from being switched on and off by mistake, and to prevent the grounding switch from being switched on by mistake when the power is on. • The rated current can reach 3150A, and the short-circuit breaking current is 31.5kA; • Pass the 4000m high altitude test; • Use vacuum arc extinguishing and air insulation; • The cabinet structure adopts the assembled type, and the circuit breaker adopts the handcart floor type structure; • The main switch can choose a novel solid-sealed pole vacuum circuit breaker or ZN85-40.5 composite insulation vacuum circuit breaker; • A screw nut pushing mechanism is installed in the handcart frame, which can easily move the handcart and prevent misoperation from damaging the pushing mechanism; •All operations can be performed with the cabinet door closed; •There is ample space in the cable room, which can connect multiple cables;
