Product Description
A switchgear is an essential, sophisticated piece of electrical equipment used primarily for opening, closing, controlling, and safeguarding electrical systems. It plays a crucial role during the generation, transmission, distribution, and conversion of power within intricate power systems.
Structure
High voltage switchgear: These systems often comprise several distinct compartments including a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each section is meticulously isolated using durable steel plates. For instance, the KYN28A-12 model is ingeniously designed with the instrument room on top, the circuit breaker room centrally located, and the cable room situated at the bottom.
Low voltage switchgear: Depending on component installation methods, these units are categorized into fixed and drawer types. The innovative drawer type switchgear features a sturdy fixed cabinet body complemented by a versatile, movable device part.
Internal Components
The core components include circuit breakers, isolating switches, load switches, operational mechanisms, transformers, and a variety of protective devices, each working in harmony to ensure optimal performance.
Classification
Switchgear classification is multifaceted: Based on circuit breaker installation, they are divided into movable and fixed types. As per cabinet structure, they are categorized into open, metal enclosed, and metal enclosed armored types. Voltage levels distinguish them into high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear. They are further classified into AC and DC types according to voltage waveform, and by purpose into incoming, outgoing, metering, and compensation cabinets.
Effect
Control Function: The switchgear efficiently manages the electrical circuit, providing seamless connectivity and disconnection, thereby facilitating precise start-stop control over power equipment.
Protection Function: In the event of circuit anomalies such as overloads, short circuits, or leakages, the switchgear promptly disconnects the circuit, ensuring the protection of both equipment and personnel.
Application Location
Its versatile use extends across various sectors including power plants, substations, petrochemicals, metallurgical steel rolling, light industry textiles, factories and mines, residential complexes, and towering high-rise buildings.
