Product Description
A switchgear is an indispensable cornerstone of electrical infrastructure, crucial for the seamless and efficient functioning of power networks. This pivotal equipment is primarily employed for the essential tasks of opening, closing, controlling, and safeguarding electrical apparatus across the entire spectrum of generation, transmission, distribution, and energy conversion processes, ensuring smooth and uninterrupted power flow.
Structure
High Voltage Switchgear: This cutting-edge apparatus comprises key sections including a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each compartment is expertly isolated with sturdy steel partitions. In the KYN28A-12 model, the layout is ingeniously crafted with the top portion as the instrument room, the middle part housing the circuit breaker room, and the lower section serving as the cable room, designed to maximize performance and safety.
Low Voltage Switchgear: Depending on the component installation method, it is classified into fixed and drawer types. The innovative drawer type features a stationary cabinet enhanced by a dynamic, movable device section, providing unparalleled flexibility and operational efficiency.
Internal Components
The internal components form the backbone of the switchgear, comprising mainly of circuit breakers, isolating switches, load switches, operating mechanisms, and transformers, supported by an extensive array of protective devices. Together, these components assure unmatched operational reliability and safety.
Classification
This advanced equipment is classified based on distinct criteria. By circuit breaker installation, it is available in movable and fixed types. The cabinet structure offers variations such as open, metal enclosed, and metal enclosed armored setups. Voltage levels classify it into high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear. Also, it divides into AC and DC switchgear based on voltage waveform, each tailored for specific applications like incoming, outgoing, metering, and compensation cabinets, among others.
Effect
Control Function: Designed with expertise, this function connects and disconnects circuits, enabling precise start-stop control of power equipment. It ensures the highest levels of operational efficiency and reliability, catering to diverse power needs.
Protection Function: Engineered with a focus on safety, this function automatically disconnects the circuit during overloads, short circuits, leakage, and other faults, thereby providing a shield to equipment and personnel against potential hazards.
Application Location
Created for broad-spectrum application, this switchgear is the ideal choice for a multitude of environments. From power plants and substations to petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, mines, as well as residential areas and high-rise buildings, it ensures unparalleled power reliability and safety across a diverse array of settings.
