Product Description
A switchgear is a paramount piece of electrical equipment, primarily utilized for the pivotal processes of opening, closing, controlling, and safeguarding electrical systems. It plays a critical role throughout the intricate phases of power generation, transmission, distribution, and energy conversion in power systems.
Structure
High Voltage Switchgear: This sophisticated equipment typically comprises a busbar room, circuit breaker room, secondary control room (often referred to as the instrument room), and a feeder room. Each section is meticulously isolated with robust steel plates for enhanced safety and efficiency. In models like the KYN28A-12, you'll find the instrument room at the top, the circuit breaker room strategically positioned in the middle, and the cable room securely located at the bottom.
Low Voltage Switchgear: Ingeniously classified into fixed and drawer types based on the component installation method. The drawer type switchgear boasts a sturdy fixed cabinet body, complemented by a versatile movable device part that offers outstanding flexibility.
Internal Components
The core components of switchgear include sophisticated circuit breakers, isolating switches, load switches, intricate operating mechanisms, transformers, and an array of protective devices designed to ensure optimal performance and safety.
Classification
Switchgear is elegantly categorized based on several criteria: Installation method of the circuit breaker distinguishes movable from fixed types. Cabinet structure divides them into open, metal enclosed, and metal enclosed armored types. Voltage levels classify them into high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear. Voltage waveform classification separates AC from DC switchgear. Furthermore, by purpose, they are organized into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: The switchgear expertly connects and disconnects circuits, facilitating precise start-stop control of power equipment, thus ensuring smooth operation across multiple applications.
Protection Function: In the event of overload, short circuit, leakage, or other faults, the switchgear adeptly severs the circuit, providing a robust layer of protection for both equipment and personnel.
Application Location
Ideal for deployment in power plants, substations, petrochemical installations, metallurgical facilities, light industry textiles, manufacturing plants, residential complexes, high-rise buildings, and numerous other locales where reliable power management is paramount.
