Product Description
The switchgear is a pivotal electrical apparatus designed to efficiently manage the opening, closing, controlling, and safeguarding of electrical equipment throughout the various stages of power systems. From generation to transmission, distribution, and energy conversion, this essential component plays a crucial role in maintaining the seamless operation of electrical systems.
Structure
High voltage switchgear: This sophisticated equipment typically comprises several distinct compartments including the busbar room, circuit breaker room, secondary control room (or instrument room), and feeder room, all securely segregated using robust steel plates. For instance, the KYN28A-12 model features a thoughtfully arranged structure where the instrument room is positioned at the top, the circuit breaker room occupies the middle section, and the cable room is situated at the bottom, ensuring optimal functionality.
Low voltage switchgear: Depending on the installation method of its components, it can be classified as either fixed or drawer type. The drawer type switchgear stands out with its innovative design, incorporating a fixed cabinet body alongside a dynamic movable device part for enhanced flexibility.
Internal Components
The switchgear's internal components are integral to its function, comprising essential elements such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an array of protective devices. Each part works in harmony to ensure the reliability and safety of the electrical system.
Classification
Switchgear can be categorized in various ways: By the circuit breaker's installation method, it is split into movable and fixed types. Based on cabinet structure, it is divided into open, metal enclosed, and metal enclosed armored types. Voltage levels distinguish between high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). It can also be differentiated by voltage waveform into AC and DC switchgear. Additionally, its purpose further classifies it into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control function: This capability allows seamless connection and disconnection of circuits, facilitating efficient start-stop control of power equipment, ensuring operational precision.
Protection function: In the event of circuit anomalies such as overload, short circuit, or leakage, the system automatically intervenes to disconnect the circuit, thereby safeguarding the integrity of the equipment and ensuring personnel safety.
Application Location
This switchgear is expertly engineered to suit a diverse array of environments, including power plants, substations, petrochemical facilities, metallurgical plants, light industry operations, factories, mines, residential complexes, and high-rise buildings, offering versatile and reliable power solutions.
