Product Description
A switchgear is a vital piece of electrical equipment, essential for the seamless operation of power systems. It plays a crucial role in the realms of generation, transmission, distribution, and energy conversion. Its primary functions encompass the opening, closing, controlling, and safeguarding of electrical apparatus, ensuring the stability and safety of electrical systems throughout these processes.
Structure
High Voltage Switchgear: This state-of-the-art equipment is a marvel of engineering, typically comprising a busbar room, a circuit breaker room, a secondary control room (also known as an instrument room), and a feeder room. Each compartment is meticulously isolated with robust steel plates to ensure safety and performance. For instance, the KYN28A-12 model features an expertly planned layout with the instrument room positioned at the top, the circuit breaker room centrally located, and the cable room at the bottom, facilitating optimal operation and safety.
Low Voltage Switchgear: Categorized by its component installation method into fixed and drawer types, this cutting-edge switchgear offers versatility and efficiency. The innovative drawer type design features a stationary cabinet body and a dynamic, movable device part, providing unparalleled flexibility and convenience.
Internal Components
Integral to the switchgear's operation, the internal components include circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a comprehensive range of protective devices. These components collaborate seamlessly to ensure reliable operation and the utmost safety, safeguarding electrical systems from potential disruptions.
Classification
This sophisticated equipment is meticulously classified by multiple criteria to suit various applications. Based on circuit breaker installation methods, it is available in both movable and fixed types. The cabinet structure itself offers open, metal enclosed, and metal enclosed armored configurations. Voltage level further distinguishes high-voltage switchgear (above AC1000V) from low-voltage switchgear (below AC1000V). Additionally, it is categorized into AC and DC switchgear according to voltage waveform, each specifically designed for applications such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, among others.
Effect
Control Function: This expertly engineered system is designed to expertly connect and disconnect circuits, providing precise start-stop control of power equipment. This ensures operational efficiency and unwavering reliability.
Protection Function: With a focus on safety, this function is engineered to automatically disconnect circuits in the event of an overload, short circuit, leakage, or other faults. This protective measure is essential for safeguarding both equipment and personnel, preventing potential hazards and ensuring peace of mind.
Application Location
Designed for broad and versatile application, this switchgear is ideally suited for a vast array of environments ranging from power plants, substations, petrochemical industries, and metallurgical steel rolling to light industry, textiles, factories, and mines. It is also perfect for residential areas and high-rise buildings, delivering power reliability and safety across a wide variety of settings.
