Frequency converter control cabinet (frequency converter electric control cabinet/electrical control cabinet) can be widely used in pumps, fans, air compressors, rolling mills, injection molding machines, belts, etc. in metallurgy, chemical industry, petroleum, water supply, mining, building materials, and motor industries. Various medium-voltage motor equipment such as transport aircraft. The frequency converter cabinet adopts a closed cabinet structure, and the protection level is generally IP55, IP56, etc. It adopts a profile frame, the surface is coated with spray plastic, and is easy to install in parallel cabinets. The upper end can be configured with a busbar, and the frequency converter panel is led out to the outside of the cabinet for direct operation. Local and remote control or PC/PLC communication control can be set as needed, and it has various intuitive display functions. The frequency converter is a special supporting product for the frequency converter cabinet. Its frequency conversion speed regulation function and main technical parameters depend on the specifications and models of the built-in frequency converter and the peripheral configuration. Frequency converter cabinets vary greatly depending on their uses and functions, and are generally customized according to industrial and mining requirements. At present, the relatively stereotyped ones include: constant pressure water supply frequency conversion cabinets (1 control 1, 1 control 2, 1 control 3, etc.), escalator frequency conversion control cabinets, central air conditioning circulating water pump frequency conversion cabinets, fan frequency conversion energy-saving cabinets, etc.
