Features of KYN28A-12 Armored Removable AC Metal Enclosed Switchgear
- Used for small to medium-sized generator power delivery in power plants, secondary substation power delivery in industrial and mining enterprises and power system control protection and monitoring of large high-voltage motors.
- Complies with IEC298, GB3906 and other standard requirements.
- Equipped with VS1(ZN63A) vacuum circuit breaker or imported VN3 vacuum circuit breaker.
- Interlocking function to prevent loaded circuit breaker handcart from pushing and pulling, mistaken tripping and closing of circuit breaker, grounding switch being closed when in the closed position, entering live compartments by mistake, and mistakenly closing grounding switches when live.
Structure of KYN28A-12 Armored Removable AC Metal Enclosed Switchgear
- The overall structure is composed of two main parts: the cabinet and the withdrawable unit (handcart) in the middle.
- The cabinet has four separate compartments with an IP4X protection level.
- When the doors of the compartments and circuit breaker compartment are open, the protection level is IP2X.
- The switchgear has various options for overhead and cable inlet and outlet, and can be arranged in different forms of power distribution devices through various combinations.
- The switchgear can be installed, debugged, and maintained from the front, allowing it to be combined back-to-back or installed against the wall, thereby improving the safety and flexibility of the switchgear and reducing the floor space occupied.
