Product Description
The switchgear from Zhejiang Chaotai Complete Equipment Co., Ltd. is a superior electrical apparatus designed for the pivotal roles of opening, closing, controlling, and safeguarding electrical systems. It plays a crucial part in the generation, transmission, distribution, and energy conversion within power systems, ensuring operational excellence and security.
Structure
High Voltage Switchgear: Typically includes compartments such as the busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, all expertly isolated by steel partitions. Take, for example, the KYN28A-12 model, which innovatively positions the instrument room at the top, the circuit breaker room centrally, and the cable room at the base for streamlined functionality.
Low Voltage Switchgear: These systems are categorized by their component installation methods into fixed and drawer types. The drawer type, in particular, is distinguished by its blend of a stationary cabinet body with an adaptable, movable device part, offering flexibility and convenience.
Internal Components
The internal framework is composed of essential elements including circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a variety of protective devices, all designed to ensure optimal performance and safety.
Classification
Classification of switchgear is multi-faceted: Based on circuit breaker installation, it is split into movable and fixed types; by cabinet structure, it encompasses open, metal enclosed, and metal enclosed armored types. According to voltage, it spans high-voltage (above AC1000V) and low-voltage (below AC1000V); by voltage waveform, it covers AC switchgear and DC switchgear. When categorized by purpose, it includes incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, each tailored for specific functions.
Effect
Control Function: Designed to deftly connect and disconnect circuits, this switchgear facilitates the precise start-stop control of power equipment, ensuring efficient operation.
Protection Function: Equipped to automatically sever the circuit in events of overload, short circuits, leakage, and other malfunctions, it upholds the safety of equipment and personnel with unwavering reliability.
Application Location
This versatile switchgear is ideal for an array of settings, including power plants, substations, petrochemical facilities, metallurgical steel plants, light industry textile operations, factories, mines, residential zones, and high-rise buildings, demonstrating its wide-ranging applicability and indispensable utility.
