The components and classification of switchgear
Classified by voltage level: High-voltage switchgear (for voltage levels of 1kV and above) and low-voltage switchgear (for voltage levels below 1kV).
Besides the protection level, what other factors affect the applicable environment of the switchgear?
Rated Voltage: Different usage environments have different voltage requirements. In industrial production, large motors, electric furnaces, and other equipment usually require higher voltages, such as 6kV, 10kV, etc., so they need switchboards that match the corresponding rated voltage.
In what environments can a distribution cabinet with an IP54 protection rating be used?
These locations typically contain a certain amount of dust, but the dust particles are relatively large and non-corrosive. An IP54 enclosure prevents large amounts of dust from entering the cabinet, protecting the internal electrical components from dust damage and ensuring normal operation.
What factors need to be considered when choosing a switchboard?
When selecting a switchgear, several factors need to be considered to ensure it meets the actual power demand and guarantees the safe and stable operation of the power system.
What are the specific differences in usage scenarios between different types of switchgear?
Different types of switchboards have distinct application scenarios. The following is a detailed introduction:
What are the common classifications of switchgear cabinets based on their structural forms?
Fixed distribution cabinets: The internal electrical components and equipment are fixedly installed, with a simple structure and low cost, but poor flexibility, and later circuit modifications or expansion operations are more complex.
How are switchboards classified according to voltage type?
Commonly used in power grids with voltage levels of 3kV and above, the internal electrical equipment has high insulation requirements, and the structural design pays more attention to safety distances and arc extinguishing capabilities. It is widely used in urban distribution networks to distribute electricity to residential areas, factories, and other places.
