Product Description
The switchgear serves as an indispensable piece of electrical equipment, expertly designed to execute crucial functions such as opening, closing, controlling, and safeguarding other electrical apparatuses. It plays a pivotal role throughout the power systems' lifecycle, including generation, transmission, distribution, and energy conversion processes.
Structure
High Voltage Switchgear: This sophisticated system typically comprises various compartments, namely the busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room. Ingeniously, each compartment is isolated with robust steel plates to ensure safety and functionality. For instance, in the KYN28A-12 model, the upper section houses the instrument room, the circuit breaker room resides in the middle, and the cable room is positioned at the bottom.
Low Voltage Switchgear: This type is classified based on the component installation method, either as fixed or drawer type. The drawer type switchgear features a sturdy fixed cabinet body complemented by a mobile device part, offering both versatility and ease of access.
Internal Components
The main internal components of the switchgear are circuit breakers, isolating switches, load switches, and operating mechanisms, all of which are vital for the system's operation. Additionally, it includes transformers and a variety of protective devices, ensuring optimal performance and safety.
Classification
Switchgear is meticulously categorized based on several criteria: By circuit breaker installation method, it can be either movable or fixed. As per cabinet structure, it is classified into open, metal enclosed, and metal enclosed armored types. Voltage levels further divide it into high-voltage (above AC1000V) and low-voltage (below AC1000V) categories. By voltage waveform, it is classified as either AC or DC switchgear. Lastly, by purpose, it is segmented into incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets among others.
Effect
Control Function: The switchgear expertly manages the circuit, enabling seamless connection and disconnection, which is essential for initiating and halting power equipment operations.
Protection Function: Equipped with advanced safety features, the switchgear promptly intervenes in instances of overload, short circuit, or leakage, automatically disconnecting the circuit to safeguard both equipment and personnel from potential hazards.
Application Location
The versatile switchgear is ideally suited for a wide range of locations, including power plants and substations, as well as petrochemical facilities, metallurgical steel rolling plants, and light industry textiles. It is also a reliable choice for factories, mines, residential areas, and high-rise buildings, providing unparalleled safety and efficiency in diverse environments.
