Product Description
Switchgear is an indispensable cornerstone of modern electrical systems, meticulously engineered to proficiently manage the opening, closing, controlling, and safeguarding of electrical apparatus throughout the power generation, transmission, distribution, and conversion journey. Its paramount purpose is to guarantee seamless and uninterrupted operation, while offering robust protection across an array of power systems.
Structure
High voltage switchgear is meticulously crafted with elegantly distinct compartments such as the busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room. Each compartment is securely, yet gracefully, isolated with steel partitions. For instance, in the KYN28A-12 model, the instrument room majestically resides at the upper section, the circuit breaker room commands the central position, and the cable room is strategically situated at the bottom.
Low voltage switchgear is ingeniously categorized based on component installation methods into fixed and drawer types. The drawer type switchgear features a robust and unwavering fixed cabinet body, harmoniously complemented by a versatile and agile movable device section.
Internal Components
Essential internal components include cutting-edge circuit breakers, isolating switches, load switches, advanced operating mechanisms, transformers, and a comprehensive suite of innovative protective devices, all meticulously harmonized to guarantee operational efficacy and unparalleled safety.
Classification
Switchgear can be expertly classified by the circuit breaker's installation method into either movable or fixed types. Cabinet structures are distinguished as open, metal enclosed, or metal enclosed armored. Voltage levels beautifully categorize them as high-voltage (above AC1000V) or low-voltage (below AC1000V), while the voltage waveform elegantly divides them into AC and DC. Additionally, they serve tailor-made functions as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: Masterfully manages circuit connectivity, enabling precise start and stop operations of power equipment, ensuring flawless control and peak performance.
Protection Function: Delivers formidable protection by automatically severing the circuit during overloads, short circuits, or leakage scenarios, thereby safeguarding both invaluable equipment and personnel from potential dangers.
Application Location
Supremely ideal for deployment in power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and towering high-rise buildings, ensuring unwavering reliable performance across a multitude of demanding environments.
