Product Description
A switchgear stands as an indispensable cornerstone in the realm of electrical equipment, serving as the heartbeat of power systems. It plays a fundamental role in executing the pivotal tasks of opening, closing, controlling, and safeguarding electrical apparatus throughout the entire spectrum of generation, transmission, distribution, and energy conversion processes. Its presence ensures seamless operation and optimized performance of power systems.
Structure
High Voltage Switchgear: This sophisticated piece of equipment is meticulously designed and typically incorporates a busbar room, a circuit breaker room, a secondary control room (often referred to as the instrument room), and a feeder room. Each section is diligently separated by sturdy steel plates to ensure optimal isolation. In models such as the KYN28A-12, strategic planning places the instrument room in the upper portion, the circuit breaker room centrally, and the cable room at the bottom, maximizing safety and performance.
Low Voltage Switchgear: Distinguished by the installation method of its components, this type of switchgear is classified into fixed and innovative drawer types. The dynamic drawer type is characterized by a stationary cabinet body paired with a versatile, movable device part, which provides unmatched flexibility and operational efficiency.
Internal Components
The internal components are the lifeblood of the switchgear's functionality, comprising critical elements such as circuit breakers, isolating switches, load switches, and operating mechanisms. Transformers along with a broad array of protective devices are also included, collectively ensuring stable and safe operations.
Classification
This advanced equipment is categorized based on a variety of criteria. The installation method of the circuit breaker classifies it into movable and fixed types, while the cabinet structure offers options like open, metal enclosed, and metal enclosed armored configurations. Voltage levels define high-voltage switchgear (for voltages above AC1000V) and low-voltage switchgear (for those below AC1000V). Furthermore, based on voltage waveform, it is divided into AC and DC switchgear, each specifically designed for particular applications such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, among others.
Effect
Control Function: Impeccably engineered to manage the connection and disconnection of circuits, this function enables precise start-stop control of power equipment, thereby ensuring efficient and reliable operation in all conditions.
Protection Function: Designed with safety as a paramount concern, this function is engineered to automatically sever the circuit in instances of overload, short circuits, leakage, and other faults, thus providing critical protection for both equipment and personnel against potential risks and hazards.
Application Location
Versatile and robust, this switchgear is crafted for seamless integration into numerous environments. It is ideally suited for settings such as power plants, substations, petrochemical industries, metallurgical steel rolling operations, as well as light industry, textiles, factories, and mines. Additionally, it offers exceptional reliability and safety for residential areas and high-rise buildings, ensuring consistent and secure power distribution in diverse applications.
