Product Description
Switchgear is an indispensable element in electrical frameworks, expertly crafted to manage the intricate processes of opening, closing, controlling, and safeguarding electrical apparatus. This pivotal component ensures uninterrupted performance and protection during power generation, transmission, distribution, and conversion phases, thereby facilitating seamless operations across diverse power systems.
Structure
High voltage switchgear is meticulously engineered with well-defined compartments, including the busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each section is securely partitioned with steel barriers, ensuring isolated functionality. Taking the KYN28A-12 model as an example, the instrument room is strategically positioned at the top, the circuit breaker room is centrally placed, and the cable room occupies the bottom portion.
Low voltage switchgear is classified based on the method of component installation into fixed and drawer types. The drawer type features a durable fixed cabinet structure and a versatile, movable device section, providing flexibility and reliability in various applications.
Internal Components
The internal architecture boasts key components such as circuit breakers, isolating switches, load switches, advanced operating mechanisms, transformers, and a host of sophisticated protective devices. These elements are meticulously synchronized to ensure maximum operational efficacy and the safety of the electrical system.
Classification
Switchgear can be classified based on the installation technique of the circuit breaker into movable and fixed types. Cabinet structures are further differentiated as open, metal enclosed, or metal enclosed armored. Voltage levels distinguish them as high-voltage (above AC1000V) or low-voltage (below AC1000V), while voltage waveform categorizes them into AC and DC. They are also tailored to serve specific roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: Skillfully manages circuit connectivity, facilitating the efficient start and stop operations of power equipment. This ensures precise control, contributing to optimal performance and reliability.
Protection Function: Offers comprehensive protection by automatically severing the circuit during incidents of overload, short circuit, or leakage, thus safeguarding both equipment and personnel from potential hazards and ensuring reliable operation.
Application Location
Engineered for excellence, this switchgear is ideal for installation in diverse settings including power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and high-rise buildings. Its robust design ensures dependable performance across a range of environments.
