CN200610065337.6 In order to minimize the height of the static power supply housing, the static power supply needs to be provided with a cable reel with a larger diameter, and its inner diameter is usually above 600mm. In addition to the space occupied by the discrete frequency converter, there is still the disadvantage that the static power supply has a larger volume

The invention discloses a static power supply with retractable cables. The static power supply comprises a frequency converter for inputting commercial frequency and commercial voltage. The frequency converter outputs stable multi-phase output voltage. The output voltage is connected with an output cable. The output cable is deployed and retracted by a cable reel for providing output voltage for loads. The static power supply with retractable cables is characterized in that the static power supply is provided with a hollow cavity that is connected with a casing, the frequency converter is arranged in the hollow cavity, the cable reel is arranged at the radially outer side of the static power supply by taking the hollow cavity and the frequency converter as the axle, a separating air channel is arranged in the hollow cavity, an output compensating cable of the frequency converter is perpendicular to a rotary shaft of the cable reel, and a supporting partitioning plate is arranged between the cable reel and the bottom plate of the casing. The static power supply with retractable cables is small in size, light in weight and convenient to maintain.
Description
technical field [0001] The invention relates to a power supply device, in particular to a cable retractable static power supply. Background technique [0002] On the apron, a static power supply is used to convert the mains power to a supply voltage that meets the requirements of the aircraft's electrical system. Generally, a 3-phase input voltage with a frequency of 50Hz or 60Hz is used, and the output is a 3-phase 400Hz AC voltage. [0003] At the airport, the cable hook was used to control the length of the cable between the aircraft and the static power supply and the storage of the cable. The cable hook used an electric hoist to hang the cable on the side of the passenger corridor bridge, and also used the cable trough basket to store the cable. The above operations were labor-intensive. Big and inconvenient to use. [0004] Currently, the use of cable reels is increasing. However, the static power supply and the cable reel are usually manufactured by different manuf...
