Product Description
A switchgear is an indispensable pillar of electrical equipment, crucial for maintaining the unbroken functionality of power systems. This essential apparatus serves pivotal roles in seamlessly opening, closing, controlling, and securing electrical devices across all phases of generation, transmission, distribution, and energy transformation.
Structure
High Voltage Switchgear: This state-of-the-art equipment typically includes a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each section is carefully isolated with sturdy steel plates. The KYN28A-12 model exemplifies this with its strategic configuration: the upper portion devoted to the instrument room, the central area for the circuit breaker room, and the lower section designated as the cable room, ensuring peak performance and maximum safety.
Low Voltage Switchgear: Based on how its components are installed, this switchgear is divided into fixed and drawer types. The groundbreaking drawer type showcases a stationary cabinet body combined with a dynamic, movable device component, delivering unparalleled flexibility and operational efficiency.
Internal Components
The internal components are the heart of the switchgear's functionality, primarily consisting of circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a wide array of protective devices, all orchestrated for reliable and safe operation.
Classification
This advanced equipment can be categorized based on several criteria. According to the circuit breaker installation method, it is available in movable and fixed types. The cabinet structure can be open, metal enclosed, or metal enclosed armored. Voltage levels classify it into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). Moreover, it is further differentiated into AC and DC switchgear based on voltage waveform, with each type tailored for specific applications such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, catering to an array of operational needs.
Effect
Control Function: With expert engineering, this function is designed to connect and disconnect circuits, ensuring the precise initiation and cessation of power equipment, thus upholding operational efficacy and dependability.
Protection Function: Designed for unmatched safety, this feature automatically disengages the circuit when confronted with overload, short circuits, leakage, and other faults, thereby protecting both equipment and personnel from potential dangers.
Application Location
Crafted for versatile use, this switchgear is ideally suited for a broad spectrum of environments, including power plants, substations, petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, and mines, as well as residential areas and high-rise buildings, ensuring power reliability and safety across a diverse array of settings.
