Product Description
Switchgear is an indispensable component in electrical systems, ingeniously crafted to masterfully handle the opening, closing, controlling, and safeguarding of electrical apparatus. It plays a crucial role during the intricate processes of power generation, transmission, distribution, and conversion. Its foremost responsibility is to guarantee smooth operations and unwavering protection across a spectrum of power systems, ensuring reliability and efficiency.
Structure
High voltage switchgear is elegantly designed with meticulously organized compartments, including the busbar room, circuit breaker room, secondary control room (or instrument room), and feeder room. Each compartment is strategically isolated with robust steel partitions. Take, for example, the KYN28A-12 model: the instrument room majestically sits at the top, the circuit breaker room is centrally and conveniently located, while the cable room finds its place at the bottom.
Low voltage switchgear boasts a classification based on the component installation method into fixed and highly adaptable drawer types. The drawer type switchgear is distinguished by a sturdy fixed cabinet body, married with a versatile, dynamic movable device section, offering flexibility and efficiency.
Internal Components
The heart of our switchgear lies in its key internal components, which include state-of-the-art circuit breakers, isolating switches, load switches, sophisticated operating mechanisms, reliable transformers, and an array of cutting-edge protective devices. These components are flawlessly harmonized to ensure unparalleled operational efficacy and heightened safety.
Classification
Switchgear is ingeniously classified by the installation method of its circuit breakers into movable and fixed types. The cabinet structures exude versatility, categorized as open, metal enclosed, or metal enclosed armored. They are further distinguished by voltage levels, labeling them as high-voltage (above AC1000V) or low-voltage (below AC1000V). Voltage waveform further segments them into AC and DC types. Additionally, they serve pivotal functions as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, among others.
Effect
Control Function: Masterfully manages circuit connectivity to facilitate and optimize the start and stop operations of power equipment, ensuring precise control and superior performance that meets the most demanding standards.
Protection Function: Delivers unwavering and robust protection by automatically severing the circuit during overloads, short circuits, or leakage events, ensuring the complete safety of both equipment and personnel from any potential risks.
Application Location
Perfectly suited for a wide array of applications, including power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and towering high-rise buildings, this switchgear ensures steadfast reliability and optimal performance across diverse and challenging environments.
