Product Description
The Switchgear is an indispensable cornerstone in modern electrical systems, engineered to proficiently oversee the intricate processes of opening, closing, controlling, and safeguarding electrical apparatuses. This pivotal role extends through power generation, transmission, distribution, and conversion phases, ensuring flawless operation and comprehensive protection within an array of power systems.
Structure
Meticulously engineered, the high voltage switchgear features a sophisticated architecture comprising distinct compartments including the busbar room, circuit breaker room, secondary control room (or instrument room), and feeder room. Each compartment is securely isolated by robust steel partitions, exemplifying superior design in the KYN28A-12 model where the instrument room presides at the top, the centrally located circuit breaker room, and the cable room at the base.
The low voltage switchgear is innovatively categorized based on component installation methods into fixed and drawer types. The drawer type boasts a sturdy fixed cabinet body coupled with a highly adaptable movable device section, offering unmatched versatility.
Internal Components
The core internal components comprise circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an array of advanced protective devices. These elements are meticulously orchestrated to ensure seamless operational efficacy and heightened safety standards.
Classification
Switchgear is thoughtfully classified by the installation method of circuit breakers into movable and fixed types. Additionally, cabinet structures are defined as open, metal enclosed, or metal enclosed armored. They are further distinguished by voltage levels, marked as high-voltage (above AC1000V) or low-voltage (below AC1000V), as well as by voltage waveform into AC and DC categories. Furthermore, switchgear fulfills diverse functions in applications such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets.
Effect
Control Function: This expertly manages circuit connectivity to seamlessly facilitate the initiation and cessation of power equipment operations, ensuring precise control and peak performance across applications.
Protection Function: It provides unyielding protection by automatically severing the circuit in instances of overloads, short circuits, or leakage events, thereby safeguarding equipment and personnel against potential hazards.
Application Location
Perfectly suited for installation in power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and high-rise buildings. This ensures dependable performance and unwavering reliability across a vast spectrum of environments.
