Product Description
A switchgear plays an indispensable role in the electrical ecosystem, serving as the backbone for efficient power system operations. This essential equipment is primarily designed to expertly manage the critical tasks of opening, closing, controlling, and safeguarding electrical apparatus across the spectrum of power generation, transmission, distribution, and energy conversion processes.
Structure
High Voltage Switchgear: This state-of-the-art equipment is typically composed of a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each compartment is painstakingly isolated using high-grade steel plates for enhanced safety. For instance, in the KYN28A-12 model, the design is strategically organized with the upper section serving as the instrument room, the central part designated as the circuit breaker room, and the lower segment as the cable room, all ensuring optimal performance and safety.
Low Voltage Switchgear: Depending on the installation method of its components, it is classified into fixed and drawer types. The cutting-edge drawer type switchgear features a static cabinet body and a dynamic, movable device section, providing unparalleled flexibility and efficiency.
Internal Components
The internal components are the heart of the switchgear's functionality, primarily including circuit breakers, isolating switches, load switches, operating mechanisms, and transformers, alongside an extensive array of protective devices, thereby guaranteeing reliable operation and utmost safety.
Classification
This sophisticated equipment is categorized based on diverse criteria. By the circuit breaker installation method, it is available in movable and fixed types. The cabinet structure offers configurations such as open, metal enclosed, and metal enclosed armored. Voltage levels discern high-voltage switchgear (above AC1000V) from low-voltage switchgear (below AC1000V). Additionally, it is segmented into AC and DC switchgear based on voltage waveform, each specifically designed for distinct applications like incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: Meticulously engineered to connect and disconnect circuits, this design facilitates the precise start-stop control of power equipment, ensuring unmatched operational efficiency and reliability.
Protection Function: Innovatively crafted for maximum safety, this function automatically disengages the circuit in the event of overload, short circuits, leakage, and other faults, effectively protecting both equipment and personnel from potential dangers.
Application Location
Designed for versatile application, this switchgear is perfectly suitable for a broad range of environments, including power plants, substations, petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, mines, residential areas, and high-rise buildings, ensuring unparalleled power reliability and safety across diverse settings.
