Product Description
A switchgear is an indispensable element of electrical infrastructure, serving as the backbone for flawless power systems operation. It is critically employed for key functions such as opening, closing, controlling, and protecting electrical apparatus throughout vital processes of generation, transmission, distribution, and energy conversion, ensuring uninterrupted electrical service.
Structure
High Voltage Switchgear: This state-of-the-art equipment comprises essential compartments, including a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, each meticulously segregated with robust steel plates. For example, the KYN28A-12 model is ingeniously configured with the upper part serving as the instrument room, the middle dedicated to the circuit breaker room, and the bottom reserved for the cable room, guaranteeing superior performance and utmost safety.
Low Voltage Switchgear: Depending on component installation methods, it is divided into fixed and drawer types. The cutting-edge drawer type switchgear boasts a stationary cabinet body and a dynamic, movable device part, delivering unmatched flexibility and operational efficiency.
Internal Components
The internal components are the heart of the switchgear's functionality, predominantly comprising circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a comprehensive array of protective devices. These elements collectively ensure dependable operation and enhanced safety standards.
Classification
This sophisticated equipment is classified using several criteria. Based on circuit breaker installation method, it is available in movable and fixed types. The cabinet structure offers open, metal enclosed, and metal enclosed armored configurations. Voltage levels dictate high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear classifications. It is further categorized into AC and DC switchgear depending on voltage waveform, each tailored for specific applications such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets.
Effect
Control Function: Ingeniously crafted to connect and disconnect circuits, this function ensures precise start-stop control of power equipment, maintaining operational efficiency and reliability.
Protection Function: Designed with safety as a priority, this function autonomously disconnects the circuit in events of overload, short circuits, leakage, or other faults, thus protecting both equipment and personnel from potential dangers.
Application Location
Designed for versatile use, this switchgear is ideally suited for a broad spectrum of environments, including power plants, substations, petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, and mines. It is also perfect for residential areas and high-rise buildings, ensuring power reliability and safety across diverse settings.
