Product Description
The switchgear is an indispensable cornerstone of electrical systems, fundamental in ensuring smooth and uninterrupted power operations. This sophisticated equipment is crucial for the pivotal tasks of opening, closing, controlling, and safeguarding electrical mechanisms across all stages, from generation and transmission to distribution and energy conversion.
Structure
High Voltage Switchgear: This state-of-the-art apparatus typically comprises a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, each diligently separated by sturdy steel barriers. For example, the KYN28A-12 model features a thoughtfully arranged design: the top section for the instrument room, the middle for the circuit breaker room, and the base for the cable room, ensuring unparalleled efficiency and safety.
Low Voltage Switchgear: Distinguished by its component installation methods, it includes both fixed and drawer types. The innovative drawer type switchgear boasts a stable cabinet structure with a dynamic, movable device component, enhancing adaptability and operational efficacy.
Internal Components
The internal components form the backbone of the switchgear's functionality, encompassing circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an extensive array of protective devices, all engineered to guarantee dependable and secure operation.
Classification
This sophisticated switchgear is categorized based on several factors. By circuit breaker installation, it is available as movable and fixed types. Its cabinet structure comes in open, metal enclosed, and metal enclosed armored designs. Classification by voltage levels distinguishes between high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). Additionally, it is split into AC and DC switchgear based on voltage waveform, each suited for specific functions such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets.
Effect
Control Function: Meticulously engineered for connecting and disconnecting circuits, it enables precise start-stop control of power apparatus, delivering outstanding operational reliability and efficiency.
Protection Function: Designed with utmost safety in mind, this feature automatically cuts off the circuit in cases of overload, short circuits, leakage, and other faults, thus protecting both equipment and personnel from potential risks and ensuring peace of mind.
Application Location
With a design tailored for extensive application, this switchgear excels in a diverse range of settings including power plants, substations, petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, mines, residential areas, and high-rise buildings, consistently ensuring power stability and safety across all environments.
