Product Description
A switchgear is a crucial piece of electrical equipment, meticulously engineered for the vital functions of opening, closing, controlling, and safeguarding electrical apparatus during the dynamic processes of power system generation, transmission, distribution, and energy transformation.
Structure
High voltage switchgear: Typically composed of a busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room, each compartment is meticulously isolated with steel plates. In the distinguished KYN28A-12 model, the upper section is designated as the instrument room, the middle section houses the circuit breaker room, and the lower section is reserved for the cable room.
Low voltage switchgear: Categorized into fixed and drawer types based on component installation methods. The elegant drawer type switchgear features a stationary cabinet body coupled with a movable device component for enhanced operational flexibility.
Internal Components
Core components include circuit breakers, isolating switches, load switches, sophisticated operating mechanisms, transformers, and a variety of protective devices, each serving a pivotal role in ensuring seamless electrical operations.
Classification
Switchgear classification is multifaceted: By circuit breaker installation, they are movable or fixed. Cabinet structure types include open, metal enclosed, and metal enclosed armored. Based on voltage, they classify into high-voltage (above AC1000V) and low-voltage (below AC1000V). Depending on voltage waveform, they are AC or DC switchgear. Purpose-driven categories encompass incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: Expertly designed to connect and disconnect circuits, this function facilitates the precise start-stop control of power equipment, ensuring optimal performance.
Protection Function: In the event of circuit overload, short circuits, leaks, and other anomalies, it automatically severs the circuit, thereby safeguarding both equipment and personnel with precision.
Application Location
Ideally suited for deployment in power plants, substations, petrochemicals, metallurgical steel rolling facilities, light industry textiles, factories and mines, residential communities, high-rise buildings, and beyond, ensuring robust energy management across sectors.
