Product Description
Switchgear is an indispensable cornerstone in modern electrical systems, meticulously engineered to adeptly orchestrate the opening, closing, controlling, and shielding of electrical apparatus during the dynamic phases of power generation, transmission, distribution, and conversion processes. Its quintessential purpose is to ensure flawless operation and unparalleled protection across a multitude of power systems, acting as a guardian and enabler of consistent energy flow.
Structure
High voltage switchgear is crafted with precision, featuring distinct compartments such as the busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room, each fortified with robust steel partitions. For instance, in the KYN28A-12 model, the instrument room claims the upper tier, the circuit breaker room commands the central space, and the cable room is strategically positioned at the base.
Low voltage switchgear is distinguished by its component installation methods, classified into fixed and drawer types. The drawer type switchgear boasts a stalwart fixed cabinet body, complemented by a dynamic movable device section, offering versatility and reliability.
Internal Components
The core internal components comprise state-of-the-art circuit breakers, isolating switches, load switches, sophisticated operating mechanisms, transformers, along with an array of advanced protective devices. These elements are seamlessly integrated to ensure unmatched operational efficacy and the highest safety standards.
Classification
Switchgear is categorized based on the circuit breaker's installation method into movable and fixed types, while the cabinet structures are classified as open, metal enclosed, or metal enclosed armored. Voltage levels further differentiate them as high-voltage (above AC1000V) or low-voltage (below AC1000V), and voltage waveform bifurcates them into AC and DC. Moreover, they are designed to serve specific roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and beyond.
Effect
Control Function: Masterfully manages circuit connectivity to seamlessly execute the start and stop operations of power equipment, ensuring precise control and exceptional performance.
Protection Function: Delivers robust protection by autonomously disconnecting the circuit during overloads, short circuits, or leakage events, safeguarding equipment and personnel from potential hazards.
Application Location
Ideally suited 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 steadfast and reliable performance across a wide array of settings.
