Compact KYN28-12 Slide-out Switchgear

KYN28-12 Modular Switchgear with Safety Features

Product Overview:

KYN28-12 high and low voltage complete cabinet is an armored removable Metal Enclosed Switchgear suitable for 3.6-12kV three-phase AC 50Hz power system. It is widely used in power plants, substations, industrial enterprises and other scenarios with high requirements for power supply reliability.

Key Highlights:

1. Robust Metal-Clad Architecture: The KYN28 Series Drawer-type Switchgear is constructed with a sturdy metal-clad design that guarantees enduring durability and shields against environmental elements. The switchgear is meticulously manufactured for secure and seamless integration into existing electrical infrastructure.

2. Flexible Switching Capabilities: It supports a broad range of vacuum circuit breakers, including the ABB VD4 and the domestically produced ZN73 (VH1), offering the adaptability to meet varying system requirements.

3. Safety-Oriented Engineering: The KYN28 Series is dedicated to safety, maintaining sufficient air insulation and creepage distances in accordance with electrical safety standards, thereby minimizing the risk of electrical accidents.

4. Extensive Protection Features: Suitable for single busbar, single busbar sectioning, and double busbar configurations, the KYN28 Series provides comprehensive protection, monitoring, and control for electrical power systems.

5. Resilient to Environmental Conditions: Designed to perform reliably across a wide range of temperatures and humidity levels, the KYN28 Series is robust against harsh environmental conditions, including seismic events, making it suitable for various geographical settings.

6. Durable Structural Design: The KYN28 Series Draw-Out Switchgear boasts a modular assembly structure with high-precision components for simplified maintenance. The switchgear's doors are made from high-quality cold-rolled steel with a long-lasting plastic coating, ensuring extended service life.

7. Effortless Operation: The central extraction mechanism of the KYN28 Series ensures smooth operation. The trolley, equipped with a screw rod transmission system, guarantees reliable movement and minimizes operational Errors.

8. Advanced Safety Mechanisms: The KYN28 Series incorporates interlocks and safety features to prevent unauthorized operations, such as closing the grounding switch with power present or moving the trolley under load, providing additional layers of safety.

Five-protection interlock and safety mechanism：

1. Prevent accidental opening and closing of circuit breakers: the circuit breaker can only be operated when the trolley is in the working/testing position. 2. Prevent the trolley from being moved with load: the trolley can only be pulled out or pushed in after the circuit breaker is opened. 3. Prevent the earthing switch from being closed with power on: the trolley must be withdrawn to the testing position before the earthing switch can be closed. 4. Prevent power from being supplied with the earthing switch: the trolley can only enter the working position after the earthing switch is opened. 5. Prevent accidental entry into the live compartment: the rear door must be unlocked after the earthing switch is closed or the power is off.
