Product Description
A switchgear is an indispensable and highly efficient electrical apparatus designed to expertly manage the opening, closing, controlling, and safeguarding of electrical equipment. It plays a pivotal role across various stages such as generation, transmission, distribution, and energy conversion in power systems, ensuring seamless and secure power management.
Structure
High voltage switchgear is a sophisticated configuration that typically comprises distinct compartments such as the busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each compartment is meticulously isolated using robust steel plates. In models like the KYN28A-12, the upper section is dedicated to the instrument room, the middle hosts the circuit breaker room, while the lower section accommodates the cable room.
Low voltage switchgear is ingeniously categorized into fixed and drawer types based on the component installation method. The drawer type switchgear boasts a fixed cabinet body complemented by a dynamic movable device part, offering versatility and ease of access.
Internal Components
The internal architecture primarily features crucial components such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an array of protective devices, each playing a vital role in ensuring operational efficiency and safety.
Classification
The classification of switchgear is multifaceted: Based on the circuit breaker's installation method, it is divided into movable and fixed types. In terms of cabinet structure, it is categorized as open, metal enclosed, and metal enclosed armored types. Voltage levels further distinguish them into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). According to the voltage waveform, they are classified into AC switchgear and DC switchgear. Lastly, their purpose differentiates them into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: This sophisticated device efficiently connects and disconnects circuits, enabling precise start-stop control of power equipment, thereby optimizing operational efficacy.
Protection Function: Equipped with advanced protection mechanisms, it automatically detects and disconnects circuits in the event of overloads, short circuits, leakages, and other faults, thus ensuring the safety of both equipment and personnel.
Application Location
This versatile switchgear is ideally suited for a diverse range of applications including power plants, substations, petrochemical facilities, metallurgical steel rolling operations, light industry textiles, and more. It is equally effective in factories, mines, residential areas, and high-rise buildings, offering unmatched reliability and performance.
