KYN28A-12 armored withdrawable indoor metal-enclosed switchgear is a complete distribution device for a single busbar and single busbar section system, designed for three-phase AC 50Hz with a rated voltage of 3.6 to 12kV. It is primarily used in power plants, system substations, medium and small generator power supply, industrial and mining enterprises, and secondary substations in power systems for receiving and distributing electrical power, as well as for the starting of large high-voltage motors.
Product Introduction:
The KYN28A-12 armored withdrawable indoor metal-enclosed switchgear is a complete distribution device for single busbar and single busbar section systems, designed for three-phase AC 50Hz with a rated voltage of 3.6 to 12kV. It is mainly used in power plants, system substations, medium and small generator power supply, industrial and mining enterprises, and secondary substations in power systems for receiving and distributing electrical power, as well as for the starting of large high-voltage motors.
Product Performance:
It has successfully passed multiple tests, including condensation, temperature rise, mechanical operation and mechanical life, insulation, short-circuit breaking and closing, and internal arc, meeting the varied needs of different users for this type of switchgear.
The grounding switch uses a quick closing mechanism and has short-circuit closing capability. The operating mechanism linkage is equipped with a mechanical interlock to prevent the insertion of the circuit breaker trolley or the inadvertent entry into a live compartment when the grounding switch is closed. The grounding switch can also be fitted with an electromagnetic lock to implement electrical interlocking between the grounding switch and other devices not in the same switchgear.
The door drive mechanism can be equipped with an electrical interlocking device to prevent the exposure of live static contacts due to misoperation when the circuit breaker trolley is in the withdrawable position, ensuring the safety of personnel and equipment.
The PMF700 series microcomputer protection device is preferably used to achieve perfect coordination between the main circuit and control circuit, and other protection devices can also be used to enable intelligent operation of the switchgear.
It ensures that circuit breaker trolleys of the same specifications are fully interchangeable.
