Product Description
Switchgear serves as a pivotal component within the realm of electrical equipment, expertly designed to efficiently manage the opening, closing, controlling, and shielding of electrical apparatus throughout the entire lifecycle of power systems. From generation through transmission, distribution, and energy conversion, switchgear ensures seamless electrical operations.
Structure
High voltage switchgear structures boast a well-organized design, typically encompassing a busbar room, circuit breaker room, secondary control room, and feeder room. Each compartment is meticulously segregated with robust steel barriers. For instance, the KYN28A-12 model is ingeniously structured with the instrument room perched at the top, circuit breaker room centrally located, and the cable room gracefully positioned below.
Low voltage switchgear exhibits versatility in design, categorized into fixed and drawer types based on component installation modes. The drawer-type switchgear ingeniously integrates a stationary cabinet with a dynamic, movable device segment to optimize space and functionality.
Internal Components
Core components include advanced circuit breakers, precise isolating switches, efficient load switches, responsive operating mechanisms, powerful transformers, and an array of sophisticated protective devices, all working in harmony to ensure optimal performance and safety.
Classification
Switchgear classification spans multiple dimensions: by circuit breaker setup as movable or fixed; by cabinet design as open, metal enclosed, or metal enclosed armored. Voltage levels delineate them into high-voltage (above AC1000V) and low-voltage (below AC1000V) categories. Voltage waveform further divides them into AC and DC switchgear. Purpose-specific varieties include incoming, outgoing, metering, and compensation cabinets, each tailored for distinct operational roles.
Effect
Control Function: Expertly facilitates the connection and disconnection of circuits, enabling precise start and stop control of power equipment, thus enhancing operational efficiency.
Protection Function: Automatically intervenes to sever the circuit amidst overload, short circuit, or leakage incidents, safeguarding both equipment integrity and personnel safety with unmatched precision.
Application Location
This versatile switchgear finds its place in a variety of settings, including power plants, substations, petrochemical facilities, metallurgical steelworks, light industrial complexes, textile factories, residential zones, towering high-rise edifices, and beyond.
