KYN28A-24 Armored Removable AC Metal Enclosed Switchgear

The KYN28A-24 Armored Removable AC Metal Enclosed Switchgear is a new generation of medium voltage AC metal enclosed switchgear and control equipment developed by our company based on the KYN28A-24 AC high voltage metal armored removable switchgear. It is suitable for three-phase AC 50Hz single bus and double bus segmented systems, mainly used in the fields of energy, industry, infrastructure, etc. for receiving and distributing electrical energy, and controlling, protecting and monitoring circuits. The rated voltage is 24KV, the rated current is up to 4000A, and the rated short-circuit breaking current is up to 40KA. The switchgear is equipped with an indoor medium voltage vacuum circuit breaker with excellent performance. The switchgear has a category of LSC2B for the continuity of operation and meets the 1.1lr temperature rise requirements.

Features of KYN28A-24 Armored Removable AC Metal Enclosed Switchgear:

  • Applicable for 20KV neutral point ungrounded power grid system, with power frequency withstand voltage of 65/79 (isolating fracture) and lightning impulse withstand voltage of 125/145 (isolating fracture)
  • Optimized design of cabinet structure, which evens out the electric field and ensures electrical clearance
  • Equipped with an overall structure and insulated fixed and sealed pole circuit breaker to enhance the insulation performance inside the cabinet
  • Uses flame-retardant shielded casing and contact box with a flame-retardant rating, and makes the electric field distribution of insulating parts more even
  • Optimized thermal convection channel to enhance heat dissipation effect
  • Programmed design: the operation of the circuit breaker handcart in and out, the operation of the grounding switch on and off, and the operation of the circuit breaker on and off can all adopt electric operation. And the on and off of split switches can be controlled by the program. The touch screen is used as the human-machine interface, and the corresponding component operation is carried out on the analog diagram provided by the touch screen
  • Remote and on-site operations can be realized, including all operations such as the handcart of the disconnector in and out and the grounding switch on and off can be realized through the background computer, and the work instructions can be revoked at any time during the operation process
  • The equipment is equipped with a variety of interlocking functions, such as the electric operation of the circuit breaker handcart in and out, the electric operation of the grounding switch on and off, etc., to prevent operators from entering the live interval by mistake
