Product Description
A switchgear is a paramount component in the realm of electrical infrastructure, deemed indispensable for the flawless functioning of power systems. This critical apparatus is deployed for pivotal tasks such as opening, closing, controlling, and safeguarding electrical equipment throughout the multifaceted processes of power generation, seamless transmission, strategic distribution, and efficient energy conversion.
Structure
High Voltage Switchgear: This state-of-the-art equipment is thoughtfully designed to comprise a sophisticated busbar room, an efficient circuit breaker room, a meticulously organized secondary control room (instrument room), and a well-planned feeder room. Each compartment is impeccably isolated with durable steel plates, ensuring peak performance and safety. For example, the KYN28A-12 model is ingeniously designed, with the upper segment serving as the instrument room, the central section acting as the circuit breaker room, and the lower part functioning as the cable room, all contributing to optimal reliability and safety.
Low Voltage Switchgear: Depending on the installation methodology of its components, it is adeptly categorized into fixed and drawer types. The innovative drawer type switchgear boasts a stationary cabinet body paired with a dynamic, movable device part, thus offering unparalleled flexibility and enhanced efficiency.
Internal Components
The internal components are the lifeblood of the switchgear, comprising primarily of circuit breakers, isolating switches, load switches, and operating mechanisms. Additionally, it includes transformers and an extensive suite of protective devices, all working in harmony to ensure robust performance and safety.
Classification
This technologically advanced equipment can be systematically classified based on diverse criteria. By circuit breaker installation method, it is available in versatile movable and fixed types. The cabinet structure offers configurations such as open, metal enclosed, and metal enclosed armored, catering to specific needs. Voltage levels further categorize it into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). It is also differentiated into AC and DC switchgear based on voltage waveform, each precisely engineered for particular applications like incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, among others.
Effect
Control Function: Ingeniously crafted to efficiently connect and disconnect circuits, it enables accurate and precise start-stop control of power equipment, ensuring consistent operational efficiency and reliability.
Protection Function: Designed with safety at the forefront, this function automatically disconnects the circuit when confronted with overloads, short circuits, leakage, and other potential faults, thereby protecting both equipment and personnel from any potential hazards.
Application Location
Expertly crafted for a multitude of applications, this switchgear is perfectly suited for a vast array of environments. From power plants and substations to the petrochemical and metallurgical steel rolling industries, light industry, textiles, factories, and mines, as well as residential areas and towering high-rise buildings, it ensures reliable power and safety across a diverse range of settings.
