KYN28A-24 Armored Removable AC Metal Enclosed Switchgear

KYN28A-24 Armored Removable AC Metal Enclosed Switchgear
KYN28A-24 armored movable AC metal enclosed switchgear is the latest generation of medium voltage AC metal enclosed switchgear and control equipment developed by our company. It is suitable for three-phase AC 50Hz single busbar and double busbar segmented systems, mainly used in energy, industry, infrastructure and other fields, as a means of receiving and distributing electrical energy, and controlling, protecting, and monitoring circuits. The rated voltage is 24kV, the maximum rated current is 4000A, and the maximum rated short-circuit breaking current is 40kA. The switchgear is equipped with indoor medium voltage vacuum circuit breakers with excellent performance. Category of loss of continuity in Project Unit Data
switchgear operation: LSC2B. Meet the temperature rise requirement of 1.1lr.

Technical Parameter

• The product is suitable for 20KV ungrounded neutral power grid systems, with a power frequency withstand voltage of 65/79 (isolation fracture) and a lightning 
• Armored Removable AC Metal Enclosed Switchgear Adopting a solidly sealed pole circuit breaker with optimized overall structure and insulation to enhance the insulation performance inside the cabinet.
• The internal structure of the cabinet is optimized and designed to evenly distribute the electric field, ensuring electrical clearance.
• Adopting flame-retardant shielding sleeves and contact boxes, the flame-retardant rating reaches grade, and the electric field distribution of insulation components is more uniform.
• Optimize thermal convection channels to enhance heat dissipation.

Technical characteristics of KYN28A-24KV armored movable AC metal enclosed switchgear

• Programmed design: The entry and exit operation of the circuit breaker handcart, the opening and closing operation of the grounding switch, and the opening and closing operation of the circuit breaker can all be electrically operated. And operate and control the opening and closing according to the program. Using a touch screen as the human-machine interface, corresponding component operations are performed on the simulation diagram provided by the touch screen.
• Remote and on-site operation: All operations, including the entry and exit of the circuit breaker handcart and the opening and closing of the grounding switch, can be achieved through a backend computer, and work instructions can be revoked at any time during the operation process.
• This device is equipped with multiple locking functions, such as electric entry and exit of circuit breaker handcart, electric opening and closing operation of grounding switch, etc., which can prevent operators from accidentally entering the live compartment.
