Product Description
Our versatile switchgear is a pinnacle of electrical engineering, designed to efficiently manage the critical operations of opening, closing, controlling, and safeguarding electrical devices within power systems. It plays a pivotal role across the entirety of power generation, transmission, distribution, and energy conversion processes.
Structure
High Voltage Switchgear: This sophisticated equipment includes a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, meticulously separated by robust steel plates. For instance, in the KYN28A-12 model, the instrument room is conveniently located at the top, the circuit breaker room is centered, while the cable room is situated at the bottom, ensuring top-tier organization and accessibility.
Low Voltage Switchgear: This category is bifurcated into fixed and drawer types, based on component installation methods. The drawer type, in particular, features a stationary cabinet frame complemented by a dynamic, movable device section, offering remarkable flexibility and ease of maintenance.
Internal Components
Our state-of-the-art switchgear is equipped with essential components such as circuit breakers, isolating switches, load switches, operational mechanisms, transformers, and a diverse array of protective devices, ensuring comprehensive safety and functionality.
Classification
Depending on installation methods, switchgear can be categorized into movable and fixed types; based on cabinet structure, it is divided into open, metal enclosed, and metal enclosed armored types. It is further classified by voltage level into high-voltage (above AC1000V) and low-voltage (below AC1000V) categories. Additionally, it is sorted by voltage waveform into AC switchgear and DC switchgear, and by purpose into specialized types such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets.
Effect
Control Function: Our switchgear is engineered to seamlessly connect and disconnect circuits, thus facilitating the smooth start-stop control of power equipment, enhancing operational precision and reliability.
Protection Function: In the event of circuit anomalies such as overloads, short circuits, or leakages, our switchgear autonomously disables the affected circuit, ensuring the utmost safety for both equipment and personnel.
Application Location
Meticulously crafted for versatility, our switchgear is ideal for deployment in diverse settings such as power plants, substations, petrochemical industries, metallurgical steel rolling facilities, light industrial textiles, a variety of factories and mines, residential areas, and towering high-rise buildings.
