Product Description
Switchgear stands as an indispensable pillar within electrical systems, intricately designed to masterfully coordinate the opening, closing, control, and safeguarding of electrical apparatus during the critical phases of power generation, transmission, distribution, and conversion. Its foremost aim is to guarantee flawless operation and unparalleled protection across a plethora of power systems.
Structure
High voltage switchgear showcases a meticulously crafted structure, comprised of distinct compartments: the busbar room, circuit breaker room, secondary control room (instrument room), and the feeder room. Each compartment is expertly secured with steel partitions. Take for example the KYN28A-12 model, where the instrument room graces the upper section, the circuit breaker room holds the central position, and the cable room completes the bottom.
Low voltage switchgear is thoughtfully categorized based on component installation methods into fixed and drawer types. The drawer type distinguishes itself with a stalwart fixed cabinet body, enriched by a versatile and dynamic movable device section.
Internal Components
The heart of the switchgear lies in its key internal components, which include circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an array of sophisticated protective devices, all seamlessly synchronized to ensure unmatched operational excellence and safety.
Classification
Switchgear is astutely classified by the circuit breaker's installation into movable and fixed types. Cabinet structures further divide into open, metal enclosed, or metal enclosed armored. Voltage levels elevate them to high-voltage (above AC1000V) or low-voltage (below AC1000V) categories, while voltage waveform distinguishes them as AC and DC. Their roles are as varied as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, among others.
Effect
Control Function: Impeccably manages circuit connectivity to adeptly facilitate the initiation and cessation of power equipment operations, guaranteeing precise control and peak performance.
Protection Function: Delivers unwavering protection by instinctively disconnecting the circuit in instances of overloads, short circuits, or leakage events, thus safeguarding both equipment and personnel from potential hazards.
Application Location
Perfectly suited for integration 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 performance across a diverse array of environments.
