Product Description
Switchgear is an indispensable cornerstone of electrical systems, masterfully engineered to manage the intricate tasks of opening, closing, controlling, and protecting electrical apparatus. Whether during the phases of power generation, transmission, distribution, or conversion, switchgear plays a pivotal role in ensuring the smooth and secure operation of power systems.
Structure
High voltage switchgear is a marvel of engineering, crafted with precision into distinct compartments: the busbar room, circuit breaker room, secondary control or instrument room, and feeder room. Each section is meticulously isolated with robust steel partitions. Take the KYN28A-12 model as an example—it features an upper instrument room, a centrally positioned circuit breaker room, and a strategically placed cable room at the base, all designed for optimal efficiency and safety.
Low voltage switchgear is innovatively designed and categorized by installation method into fixed and drawer types. The drawer type stands out with its sturdy fixed cabinet body, complemented by a flexible, easily maneuverable device section, ensuring adaptability and reliability.
Internal Components
The switchgear houses an array of critical internal components, including circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of advanced protective devices. These components work in perfect harmony to assure both operational efficiency and the utmost safety standards.
Classification
Switchgear systems are precisely classified based on the circuit breaker's installation method into movable and fixed types. Their cabinet structures are elegantly categorized as open, metal enclosed, or armored. They are further distinguished by voltage levels into high-voltage (above AC1000V) and low-voltage (below AC1000V), and by voltage waveform into AC and DC types. Functionally, they are tailored as incoming, outgoing, metering, compensation cabinets, and more, each serving specific electrical needs.
Effect
Control Function: This function adeptly manages the connectivity of circuits to seamlessly initiate and halt power equipment operations, ensuring precise control and peak performance at all times.
Protection Function: Offers formidable protection by automatically severing the circuit during overloads, short circuits, or leakages, thereby safeguarding equipment and personnel from potential hazards and ensuring peace of mind.
Application Location
Perfectly suited for deployment in a vast array of environments, including power plants, substations, petrochemical sites, metallurgical and steel operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and skyscrapers. It guarantees robust and reliable performance, meeting the demands of diverse and challenging settings.
