Product Description
Switchgear serves as a cornerstone in modern electrical systems, a sophisticated apparatus engineered to masterfully handle the intricacies of power generation, transmission, distribution, and conversion. It excels in the critical tasks of opening, closing, controlling, and protecting electrical apparatus, ensuring the consistent and safe operation of various power systems.
Structure
High voltage switchgear boasts a meticulously organized structure, featuring distinct compartments such as the busbar room, circuit breaker room, secondary control room (often referred to as the instrument room), and feeder room. Each of these compartments is safely isolated with durable steel partitions. Taking the KYN28A-12 model as an example, the instrument room is strategically positioned at the top, the circuit breaker room is centrally located, and the cable room is efficiently placed at the bottom.
Low voltage switchgear is sophisticatedly categorized based on how components are installed, either as fixed or drawer types. The drawer type switchgear is meticulously designed with a sturdy fixed cabinet body, enhanced by a highly versatile movable device section, providing flexibility and reliability.
Internal Components
The switchgear's core is composed of essential internal components, including circuit breakers, isolating switches, load switches, operating mechanisms, and transformers, all working in concert with a suite of advanced protective devices to ensure unmatched operational efficacy and safety.
Classification
Switchgear can be adeptly classified by the circuit breaker's installation method into movable and fixed types. The cabinet structures are distinctly designed as open, metal enclosed, or metal enclosed armored. They are differentiated by voltage levels into high-voltage (above AC1000V) or low-voltage (below AC1000V), and by voltage waveform into AC and DC types. Moreover, they are tailored to serve specific roles such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, providing versatile solutions for diverse applications.
Effect
Control Function: Precisely orchestrates circuit connectivity, enabling the seamless start and stop operations of power equipment, ensuring exceptional control and peak performance across systems.
Protection Function: Delivers robust protection by automatically severing the circuit during overloads, short circuits, or leakage incidents, effectively safeguarding equipment and personnel from potential hazards.
Application Location
Perfectly suited for deployment in diverse environments such as power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and high-rise buildings, delivering reliable and consistent performance across these varied settings.
