Description

Reliable and High-Performance Circuit Breaker

One of the protrude features of the Box-Type Fixed AC Metal-Enclosed Switchgear is its high-reliability circuit breaker. The breaker ensures stable operation with good performance performance, reducing the risk of failures and enhancing system safety. Its robust construction allows it to handle demanding electrical environments effectively, making it suitable for both primary and backup power distribution networks.

Advanced Safety Mechanisms

Safety is a top priority in the Box-Type Fixed AC Metal-Enclosed Switchgear. It includes a comprehensive “Five Prevention” ("Five-Proof") interlocking system that prevents misoperation and ensures personal safety. The interlocking system is simple yet effective, reducing the likelihood of operational errors while enhancing overall system security.

Wide Range of Applications

The Box-Type Fixed AC Metal-Enclosed Switchgear is suitable for various applications, including power generation plants, substations, industrial enterprises, and high-rise buildings. It is also compatible with ring main units and can be used in switching stations to enhance power distribution efficiency. Its flexibility makes it a valuable component in modern power systems, ensuring stable and secure energy distribution.

Robust Structural Features

The Box-Type Fixed AC Metal-Enclosed Switchgear features a high-quality welded steel frame, ensuring durability and long-term reliability. The breaker compartment is positioned in the middle or lower part of the cabinet, facilitating easy installation, maintenance, and operation. The standard configuration includes a VS1 circuit breaker, which is known for its stability and safety.

Additionally, the switchgear cabinet is equipped with a pressure release channel to enhance safety by preventing excessive internal pressure build-up. The use of a rotary-type isolating switch allows maintenance personnel to safely access the breaker compartment without shutting down the entire system, ensuring convenience and operational continue.

Enhanced Protection and Locking Mechanisms

The Box-Type Fixed AC Metal-Enclosed Switchgear is designed with a reliable mechanical locking system that meets high safety standards. The enclosure has an IP2X protection rating, effectively preventing accidental contact with live components. Further, it incorporates a strong grounding system to enhance operational safety and reliability.

A well-positioned observation window allows users to monitor the internal components and operational status without opening the cabinet. The locking mechanism is designed to be user-friendly, following the structure of the JSXGN locking system found in the XGN2-12 switchgear. This makes it simple, practical, and highly effective for ensuring proper interlocking.

Convenient Cable Management and Installation

The Box-Type Fixed AC Metal-Enclosed Switchgear offers user-friendly cable management. The incoming and outgoing cables are positioned at the lower front section of the cabinet, allowing for straightforward connection and efficient space utilization. This design simplifies the installation process, reducing the time and effort required for setup.

Environmental Adaptability

The Box-Type Fixed AC Metal-Enclosed Switchgear is built to withstand a wide range of environmental conditions. It is designed to operate efficiently in altitudes up to 1000 meters and temperature ranges from -25°C to 40°C, with a the largest 24-hour average temperature of 35°C. The structure is capable of handling seismic intensity up to 8 degrees, ensuring stability even in areas prone to earthquakes.

The Box-Type Fixed AC Metal-Enclosed Switchgear is an advanced, space-saving, and high-performance electrical distribution solution. With its compact design, high-reliability circuit breaker, enhanced safety features, and broad application range, it is an good performance choice for power generation plants, substations, industrial facilities, and commercial buildings.
