Product Description
A switchgear is a pivotal electrical component, meticulously designed to proficiently manage the opening, closing, controlling, and safeguarding of electrical systems. This sophisticated equipment is integral to the seamless processes of power generation, transmission, distribution, and energy conversion within advanced power systems.
Structure
High voltage switchgear: Typically composed of various meticulously designed compartments such as the busbar room, circuit breaker room, secondary control room (often referred to as the instrument room), and feeder room. Each compartment is expertly segregated using durable steel plates. In the esteemed KYN28A-12 model, the instrument room occupies the upper section, the circuit breaker room is centrally located, while the cable room resides at the base.
Low voltage switchgear: Categorized into fixed and versatile drawer types based on component installation methods. The drawer type switchgear is ingeniously engineered with a stationary cabinet framework and a mobile device section, ensuring optimal flexibility and efficiency.
Internal Components
This sophisticated equipment predominantly comprises critical components such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, along with an array of protective devices essential for robust performance.
Classification
Classification is multi-faceted: Circuit breakers can be installed in either movable or fixed configurations. The cabinet structure itself may be open, metal-enclosed, or metal-enclosed armored. Voltage classification distinguishes between high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear. Furthermore, it is segmented into AC and DC types based on the voltage waveform, and by functionality into various specialized cabinets including incoming, outgoing, metering, and compensation cabinets.
Effect
Control Function: The switchgear enables precise control over power equipment by effectively connecting and disconnecting circuits, facilitating seamless start-stop operations.
Protection Function: In the event of circuit anomalies such as overload, short circuit, or leakage, the system autonomously disconnects the circuit, thereby safeguarding both equipment integrity and personnel safety.
Application Location
Tailored for diverse environments, this product finds its utility in power plants, substations, petrochemical industries, metallurgical and steel rolling sectors, light industry textiles, factories, mines, residential zones, and towering high-rise buildings.
