Product Description
A switchgear is the pinnacle of electrical equipment engineering, designed to seamlessly open, close, control, and protect electrical apparatus during the crucial processes of power generation, transmission, and distribution, as well as during energy conversion within complex power systems.
Structure
High voltage switchgear is a sophisticated assembly usually comprising a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, all meticulously isolated with robust steel plates. In models such as KYN28A-12, the upper echelon features the instrument room, the core is the circuit breaker room, and the foundation is the cable room, ensuring optimal functionality and safety.
Low voltage switchgear is ingeniously categorized into fixed and drawer types based on the installation method of its components. The drawer type, in particular, boasts a fixed cabinet body complemented by a versatile movable device section, offering unparalleled flexibility and efficiency.
Internal Components
The heart of the switchgear system includes indispensable components such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, alongside a suite of protective devices, all working in harmony to ensure flawless operation.
Classification
Switchgears are classified with precision: based on circuit breaker installation, they are either movable or fixed; cabinet structures vary from open to metal enclosed and metal enclosed armored types; voltage levels delineate them into high-voltage (above AC1000V) and low-voltage (below AC1000V) categories; voltage waveform categorizes them into AC and DC switchgears; and according to their purpose, they are meticulously divided into incoming, outgoing, metering, and compensation cabinets, each serving a specific role with expertise.
Effect
Control Function: With adeptness, it connects and disconnects circuits, enabling precise start-stop control of power equipment, thus ensuring efficient and reliable operations.
Protection Function: When faced with circuit anomalies such as overloads, short circuits, or leakages, it promptly cuts off the circuit, safeguarding the integrity of equipment and the safety of personnel with automatic precision.
Application Location
This switchgear finds its optimal applications across a diverse array of locations: power plants, substations, petrochemical sites, metallurgical steel rolling facilities, light industry textiles, factories, mines, residential zones, and towering high-rise buildings, proving its versatility and adaptability in varied environments.
