Product Brief

Central cabinet

Kyn28-12 (z) armored movable AC metal enclosed switch cabinet is the central cabinet, also known as armored switch cabinet, handcart type switch cabinet and 28 cabinet. It is divided into three layers: the upper layer is the bus bar and instrument room (isolated from each other), the middle layer is the circuit breaker room, and the lower layer is the cable room. It is suitable for three-phase AC 50 Hz, 3.6 ~ 12 kV single bus section system complete set of power distribution device, as receiving and distributing network power, and implementing control, protection and monitoring of the circuit. Because the load power of the central cabinet is large, it is widely used in electric power, metallurgy, petrochemical, urban construction and other industries.

advantage

1. The protection level is high. The middle cabinet adopts armored aluminum zinc plate shell, and the protection grade is IP4X.

2. The main switch of high-voltage central cabinet adopts handcart vacuum circuit breaker, which is safe to operate. When replacing, it is only necessary to manually pull out the handcart and replace it with a new switch. There is no need for power failure and convenient maintenance.

3. Because of its strong load capacity, high voltage central cabinet is often used in large load distribution system because of its material selection and appearance design.

4. The five prevention interlocking is perfect. There is a perfect five prevention interlock between the handcart of the circuit breaker in the central cabinet, the grounding switch and each compartment, so as to prevent the safety accidents caused by misoperation.

purpose

Kyn28-12 central cabinet is suitable for three-phase AC 50 Hz, 3.6 ~ 12 kV high-voltage distribution system, as receiving and distributing high-voltage network power, and monitoring and protecting the circuit. It is commonly used in power stations, metallurgy, petrochemical, large factories, residential buildings, schools, urban public buildings and other industries.

Draw out vacuum circuit breaker

Kyn28-12 central cabinet adopts handcart vacuum circuit breaker as the main switch, which can be maintained and inspected under the condition of continuous power supply修，拥有可靠的联锁，操作安全，使用方便。

The shell material selection process is excellent

The shell of high-voltage central cabinet is made of aluminum zinc plate, which is assembled by multiple bending. The surface of high-voltage central cabinet is made of metal armor technology隔开，外壳防护等级为IP4X。

Comprehensive relay protection

High voltage central cabinet is installed with high-quality integrated relay protector, which can cut off the power supply quickly and send out alarm signal in case of over-current and short-circuit fault in the power supply system. The intelligent monitoring equipment is safe and stable运行。

Enough space is reserved inside

The internal compartments of the high-voltage central cabinet are separated by metal partitions, and sufficient space is reserved to facilitate maintenance and rectification. The bus room has sufficient space to connect multiple cables.
