Product Description
Switchgear is an indispensable element within electrical systems, meticulously engineered to adeptly handle the intricate functions of opening, closing, controlling, and fortifying electrical apparatus. It plays a pivotal role throughout the stages of power generation, transmission, distribution, and conversion, ensuring uninterrupted operation and comprehensive protection across a myriad of power systems.
Structure
High voltage switchgear boasts a precision-engineered structure, configured with discrete compartments such as the busbar room, circuit breaker room, secondary control room (also referred to as the instrument room), and feeder room. Each section is securely segregated with robust steel partitions. Specifically, in the KYN28A-12 model, the instrument room is strategically placed at the top, the circuit breaker room is centrally located, and the cable room is positioned at the bottom, ensuring optimal organization and functionality.
The low voltage switchgear is classified based on the installation method of its components into fixed and drawer types. The drawer type switchgear features an exceptionally sturdy fixed cabinet body, enhanced by a flexible and adaptable movable device section, offering versatile and efficient operation.
Internal Components
The switchgear's core internal components include circuit breakers, isolating switches, load switches, operating mechanisms, transformers, along with a series of cutting-edge protective devices. These components work in harmony to ensure unparalleled operational efficiency and safety, making them critical to the reliable functioning of power systems.
Classification
Switchgear is categorized based on the installation method of the circuit breaker into movable and fixed types. The cabinet structures themselves are classified as open, metal enclosed, or metal enclosed armored. Furthermore, they are delineated by voltage levels into high-voltage (exceeding AC1000V) or low-voltage (under AC1000V). Additionally, the voltage waveform further classifies them into AC and DC types. They serve tailored roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and beyond.
Effect
Control Function: Expertly orchestrates circuit connectivity, enabling precise start and stop functions for power equipment. This ensures precise control and peak performance of the systems.
Protection Function: Delivers comprehensive protection by automatically severing the circuit during overloads, short circuits, or leakage scenarios, offering robust safety for both equipment and personnel against potential hazards.
Application Location
Perfectly suited for integration within power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing arenas, mining enterprises, residential complexes, and high-rise buildings. It assures steadfast, reliable performance across a wide spectrum of environments.
