Product Introduction
Enclosure of KYN Series High-Voltage Switchgear
I. Product Overview
The enclosures of this series of high-voltage switchgear are designed and manufactured in strict accordance with the standards of GB/T 3906 AC Metal-Enclosed Switchgear and Controlgear for Rated Voltages from 3.6kV to 40.5kV and IEC 62271-200. They are specifically tailored for mainstream models such as KYN28A-12 and KYN61-40.5. Serving as the "skeleton" and "skin" of the switchgear, what we provide is not merely an outer shell, but a comprehensive protection solution integrating "extreme safety, outstanding performance, and long-term stability". It serves as a solid foundation for ensuring the safe operation of core components in the power system.
II. Core Structural Design Features
1. High-Strength Integral Frame Structure
High-Quality Aluminum-Zinc-Coated Steel Plate/Galvanized Steel Plate: The main body is made of high-quality imported cold-rolled steel plates. After CNC sheet metal processing, it undergoes a "multi-layer anti-corrosion process" (degreasing, phosphating, passivation, electrostatic spraying), ensuring the enclosure has strong corrosion resistance and rust resistance, suitable for various harsh environments.
Multi-Fold Edging and Reinforcement Rib Design: The layout of reinforcement ribs at key load-bearing parts and innovative reinforcement rib arrangements significantly enhance the "mechanical strength" and "rigidity" of the enclosure. It can effectively resist mechanical stress generated during transportation, installation, and operation, as well as the impact of internal fault arcs, ensuring no deformation of the cabinet.
Modular Design: Adopting a standard modular size design, it facilitates large-scale production, transportation, and on-site installation. At the same time, it supports flexible "non-standard customization" — dimensions and layouts can be quickly adjusted according to customer needs, with strong compatibility.
2. Scientific and Precise Compartment Division
Full-Condition Isolation Protection: The enclosure is strictly divided into four mutually isolated and independent compartments: "Circuit Breaker Compartment, Busbar Compartment, Cable Compartment, and Low-Voltage Instrument Compartment".
Metal Partition Isolation: High-quality metal partitions are used to completely isolate the compartments, effectively preventing mutual interference between functional units and the spread of faults.
Reliable Safety Interlocking: Through precise mechanical interlocking devices, the "five anti-misoperation" requirements are strictly followed. This ensures that operations can only be performed under fully safe conditions (e.g., the handcart compartment door can only be opened when the circuit breaker is in the open state), eliminating misoperations from the structural root.
3. Advanced Pressure Relief Channel and Safety Protection
Directional Active Pressure Relief System: This is the top priority in the enclosure design. "Dedicated pressure relief channels" are installed at the top of both the Circuit Breaker Compartment and the Cable Compartment. In the event of an internal fault arc, high-temperature and high-pressure gas can be quickly discharged upward along the preset path, effectively "releasing pressure" and maximizing the safety of operators and surrounding equipment.
High-Strength Pressure Relief Cover: A specially designed pressure relief cover is equipped at the outlet of the pressure relief channel. It remains sealed and dustproof under normal conditions, and can automatically open quickly in case of deflagration, then reset automatically after pressure relief.
4. Excellent Protection and Sealing Performance
High Protection Level: The enclosure achieves a protection level of "IP4X", and the protection level between compartments reaches "IP2X". High-quality sealing strips are used at the edges of the door panels, effectively preventing dust, moisture, and small animals from entering, ensuring internal components operate in a clean environment.
Automatic Opening and Closing System for Valve: An exquisite "insulated valve mechanism" is designed. When the handcart is moved away, the valve automatically and reliably closes to completely isolate the live busbar; when the handcart moves into the working position, the valve automatically opens. This process is safe, reliable, and requires no manual intervention.
5. Humanized and Convenient Design
Spacious Operation and Observation Space: The Cable Compartment and Circuit Breaker Compartment have ample space, facilitating cable wiring, installation, and maintenance. A large observation window is installed on the front door, allowing real-time observation of the operating status of equipment inside the cabinet.
Convenient Grounding Design: A dedicated "grounding busbar" and sufficient connection points are provided to ensure good grounding of all metal components, ensuring safety and reliability.
High-Quality Surface Treatment: The appearance adopts "orange-peel texture" or "fine sand texture" surface treatment, which is not only elegant in appearance but also features scratch resistance and corrosion resistance.
