Product Description
A switchgear is an indispensable component in the realm of electrical equipment, playing a pivotal role in the efficient operation of power systems. This essential apparatus is meticulously designed to perform the critical tasks of opening, closing, controlling, and protecting electrical setups across the entire spectrum of power generation, transmission, distribution, and conversion processes.
Structure
High Voltage Switchgear: This state-of-the-art equipment is composed of a busbar room, circuit breaker room, secondary control room (also known as the instrument room), and a feeder room. Each section is expertly isolated using durable steel plates for enhanced safety and performance. For example, the KYN28A-12 model showcases an intelligent layout: the upper section serves as the instrument room, the middle section houses the circuit breaker room, and the lower section is designated as the cable room, all contributing to superior operational efficiency and safety.
Low Voltage Switchgear: Distinguished by its installation method, this switchgear is available in fixed and drawer types. The innovative drawer type is particularly notable for its stationary cabinet body, coupled with a versatile, movable device component, granting heightened flexibility and operational efficiency.
Internal Components
The internal components are the lifeblood of the switchgear's functionality, primarily comprising circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an extensive array of protective devices, all working in harmony to ensure seamless, safe, and reliable operation.
Classification
This sophisticated switchgear is classified according to several criteria. Based on the installation method of the circuit breakers, it is available in movable and fixed types. The cabinet structure is offered in open, metal enclosed, and metal enclosed armored designs. Voltage levels classify it into high-voltage switchgear (exceeding AC1000V) and low-voltage switchgear (below AC1000V). Additionally, it is divided into AC and DC switchgear based on voltage waveform, with specialized configurations for applications such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets.
Effect
Control Function: With expert engineering, this switchgear adeptly manages the connection and disconnection of circuits, enabling precise start-stop control of power equipment, thereby ensuring operational excellence and unwavering reliability.
Protection Function: Designed with cutting-edge safety technology, this function autonomously disengages the circuit when confronted with conditions like overload, short circuits, leakage, and other faults, thereby protecting both the equipment and personnel from potential dangers, ensuring peace of mind.
Application Location
Designed for a diverse range of applications, this versatile switchgear is ideally suited for various environments, from power plants and substations to petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, and mines, as well as residential areas and high-rise buildings, guaranteeing reliable power and safety across a wide array of settings.
