Product Description
A switchgear is an indispensable powerhouse of electrical equipment, playing a critical role in ensuring the flawless operation of power systems. This essential apparatus is primarily utilized for the vital functions of opening, closing, controlling, and safeguarding electrical devices throughout the entire lifecycle of power systems, including generation, transmission, distribution, and energy conversion processes.
Structure
High Voltage Switchgear: As a pinnacle of advanced engineering, this sophisticated equipment typically comprises a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, each meticulously partitioned using solid steel plates for enhanced safety. For instance, the KYN28A-12 model boasts a strategic layout: the upper portion is an instrument room, the central section houses the circuit breaker room, and the lower area serves as the cable room, ensuring superior safety and performance.
Low Voltage Switchgear: Tailored based on the installation methods of its components, it is available in both fixed and innovative drawer types. The revolutionary drawer type switchgear features a stationary cabinet body paired with a dynamic, movable device part, providing unmatched flexibility and operational efficiency.
Internal Components
The internal components are the backbone of the switchgear's functionality, encompassing vital elements such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, along with a comprehensive suite of protective devices. These components work in harmony to ensure unparalleled reliability and safety of operations.
Classification
This cutting-edge equipment can be adeptly classified by a multitude of criteria. By circuit breaker installation method, it is available in both movable and fixed types. It boasts cabinet structures in open, metal enclosed, and metal enclosed armored configurations. Based on voltage levels, it is classified into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). Furthermore, it is divided into AC and DC switchgear based on voltage waveform, each meticulously engineered for specific applications like incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, among others.
Effect
Control Function: With expert precision, this switchgear is engineered to deftly connect and disconnect circuits, facilitating the precise start-stop control of power equipment, thereby ensuring operational efficiency and consistent reliability.
Protection Function: Masterfully crafted with safety in mind, this function is designed to automatically disconnect the circuit under conditions of overload, short circuits, leakages, and other faults, thereby providing robust protection to both equipment and personnel against potential hazards.
Application Location
Expertly designed for versatility, this switchgear is ideally suited for a vast array of environments, including power plants, substations, petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, mines, as well as residential areas and towering high-rise buildings, ensuring unwavering power reliability and safety across diverse settings.
