KYN10-40.5 Armored Drawout AC Metal-Clad Switchgear

The KYN10-40.5 Armored Drawer-Type AC Metal-Enclosed Switchgear is an indoor metal-enclosed handcart cabinet designed for three-phase AC systems with a frequency of 50Hz and a rated voltage of 25-40.5kV. As a professional AC Metal Clad Switchgear, it is widely used in power plants, substations, and other locations, suitable for single-bus and single-bus segmented systems for power reception, distribution, and control.

 

This product supports various circuit breaker configurations, including vacuum circuit breakers (such as ZN23, ZN12, 3AH series) and SF6 circuit breakers (such as LN2, FP series) to meet diverse distribution needs. It strictly adheres to the national standard GB3906 "3-35kV AC Metal-Enclosed Switchgear."

 

 

Environmental Adaptability

 

 

Ambient Temperature: -15°C to +40°C, daily average ≤35°C

Altitude: ≤1000m

Humidity Requirements: Daily average relative humidity ≤95%, monthly average ≤90%

Seismic Intensity: ≤8 degrees

Environmental Requirements: No corrosive gases, flammable gases, steam, or salt pollution; no severe vibration

Special Environments: Customization available upon consultation for conditions beyond the above.

*Note: Overhead incoming/outgoing line cabinets require an additional 800mm deep auxiliary cabinet.*

1.Sturdy and Durable Cabinet: The cabinet is made of cold-rolled steel plates formed by bending and welding, ensuring stable structure and precise dimensions. The surface is smooth and aesthetically pleasing, with strong anti-rust and anti-corrosion properties, offering durability and low maintenance.

2.Strong Interruption Capability: The maximum short-circuit breaking current can reach 31.5kA, quickly cutting off current during faults to protect equipment and personnel. It is suitable for power stations and plants with high requirements for power supply reliability.

3.Excellent Insulation of Mutual Inductors: Utilizes contactor-type current transformers with a compact size and excellent insulation performance, effectively preventing partial discharge and ensuring more stable operation.

4.Effortless Handcart Operation: Employs a worm gear propulsion mechanism for smooth and easy operation. Even a heavy handcart can be easily pushed or pulled by one person, facilitating daily maintenance.

5.Reliable Secondary Plug Connection: The secondary plug uses a sliding structure that automatically connects or disconnects when the handcart moves. The plug-in process is simple, with accurate positioning and good contact, ensuring more stable control signal transmission.

6.Safer Independent Compartments: Functional units inside the cabinet (such as the breaker chamber, busbar chamber, and cable chamber) are completely separated by metal plates. Each compartment has an independent pressure relief channel. In case of an internal fault, pressure can be directed to protect operators and adjacent equipment. This compartmentalized design significantly enhances the safety and reliability of this switchgear in power system applications.

7.Supports Customization: Circuit breakers can be vacuum or SF6. Devices like surge arresters and voltage indicators can be installed based on requirements. Cabinet colors can also be adjusted. For special operating environments or wiring schemes, customization is available upon consultation to ensure the equipment meets site requirements.

Please provide the following information when ordering to ensure accurate product matching:

Main circuit scheme number, main wiring system diagram, layout diagram, floor plan;

Auxiliary circuit and control circuit wiring schematic diagram, terminal block layout;

Model, specification, and quantity of components inside the cabinet;

Whether to add a surge arrester (circuit breaker handcart);

Whether to configure a voltage indicating device;

Cabinet color requirements (if no special request, the company standard will be used);

Special operating environment or other technical requirements.

The KYN10-40.5 switchgear is widely used in various medium and high voltage distribution situations, mainly applicable in the following scenarios:

Power Plants: Used as generator outlet breaker cabinets or auxiliary power distribution cabinets for power transmission and distribution, requiring stable operation and reliable protection.

Substations: Suitable for 25-40.5kV voltage level substations as incoming/outgoing line cabinets, bus tie cabinets, or feeder cabinets for power reception, transmission, and control. The handcart structure facilitates maintenance and reduces downtime.

Industrial Enterprises: In distribution rooms of large factories like steel, chemical, and cement plants, where equipment operates continuously, requiring high durability and operational convenience. Different circuit breakers can be configured flexibly based on site needs to adapt to various loads. The robust design and flexible configuration of this AC Metal Clad Switchgear in power system environments like industrial plants ensure continuous operation.

Municipal Infrastructure: In critical locations like airports, hospitals, large shopping malls, and data centers, as main power distribution equipment, requiring continuous and reliable power supply and the ability to quickly isolate faults for maintenance.

New Construction or Renovation Projects: Suitable for upgrading old distribution rooms. The cabinet size and installation method support flexible adjustments, minimizing civil works modifications.
