Description
KYN28 series armored metal enclosed switchgear is suitable for indoor three-phase 50/60HZ, rated voltage 24kV power system. Mainly used in power plants, substations, industrial and mining enterprises and high-rise buildings.It is used to receive and distribute electric energy and control, protect and monitor the circuit.
The KYN28A switchgear has various functions to prevent misoperation, including preventing the handcart from moving with load, preventing the grounding switch from closing the circuit breaker, preventing the live grounding switch from closing, and preventing accidental entry into the live compartment.
The switchgear is equipped with VS1, VN2 series of high-voltage AC vacuum circuit breakers and solid-sealed vacuum switches with excellent performance.
The secondary circuit of the switchgear is equipped with advanced and reliable control and protection components; the busbar adopts heat-shrinkable insulation material or bad oxygen-coated insulation means, optimizes the shape of the electrode, and the cabinet structure is compact.
The switchgear is a power distribution device with advanced technology, stable performance, reasonable structure, convenient use, safe and reliable.
