Product Description

 

Product Description

 KYN28A-24 armored removable AC metal-enclosed switchgear (hereinafter referred to as switchgear), suitable for indoor three-phase 50/60Hz, rated voltage 24kV power system, mainly used in power plants, substations, industrial and mining In enterprises and high-rise buildings, as a means of receiving and distributing electrical energy and controlling, protecting and monitoring circuits.

The KYN28A-24 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 grounding switch from being energized, and preventing accidental entry into the live compartment. The switchgear is equipped with VS1, VN2 series medium-mounted 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 epoxy-coated insulation means to optimize the shape of the electrode, and the cabinet structure is compact. The switchgear is advanced in technology, stable in performance and reasonable in structure. Easy to use, safe and reliable power distribution equipment.

Installation Instructions

Model meaning

Operating conditions
1.+15°C~+40°C. And the average value measured within 24 hours shall not exceed 35°C
2.The average monthly relative humidity shall not exceed 90%
The average monthly water vapor pressure shall not exceed 1.8kPa;
3.Altitude: ≤1000m.
4.There is no obvious dust or smoke in the surrounding air: pollution caused by corrosive or combustible gases, vapors, or salt mist;
5.Vibration or ground motion from outside the switchgear and control equipment can be ignored;
6.The amplitude of electromagnetic interference induced in the secondary system shall not exceed 1.6kV

Special use environmental conditions
1,When the switchgear is used under normal environmental conditions as specified in this instruction manual, the company andthe user may negotiate and agree on special operating conditions that exceed normal operating conditions.
2,In order to prevent condensation, the swltch cabinet is equlpped with a heater. When the switchgear is in standby, it should beput into use.Even in normal operation, you should pay attention to the application.
3,The heat dissipation problem of the switchgear can be salved by additional ventilation.

Main feature
1.The cabinet is made of aluminum-zinc coated sheet processed by CNC equipment and assembled with bolts or rivets, with a fully modular structure.
2.This switchgear has various functions to prevent misoperations, including preventing loaded trolleys from moving, preventing live coupling and earthing switches, and preventing inadvertent entry into live compartments.
The switchgear is equipped with high-quality VS1 series center-mounted AC high- voltage vacuum circuit breaker and fixed-sealed vacuum circuit breaker.
The busbar adopts heat-shrinkable insulation material as the insulation means, optimized electrode shape, and compact cabinet structure.
This switchgear is an advanced, stable performance, reasonable structure, easy-to- use, safe and reliable power distribution equipment.
