Description

Technical Field

[0001] This utility model relates to a mobile cable transfer and distribution cabinet. Background Technology

[0002] Currently, most aircraft maintenance equipment in large repair hangars is powered by electricity drawn from the hangar's electrical distribution room and distributed through circuits to multiple fixed distribution boxes or terminals. These distribution boxes or terminals provide multiple power access points for the maintenance equipment. During maintenance, the nearest distribution box or terminal can be selected based on demand. However, limitations imposed by the length of equipment cables and the installation location of power access points restrict the use of aircraft maintenance equipment, especially in large repair hangars where areas far from the power grid often have low utilization rates, resulting in idle and wasted maintenance space.

[0003] The existing power supply methods have the following problems and disadvantages: 1. For large repair hangars that use fixed distribution boxes / pile power distribution, the power supply to maintenance equipment is limited by the location of the distribution box and the length of the cable, thus restricting the area of ​​use. To overcome this difficulty, the cable length of the electrical equipment can usually be extended or a fuel-powered power supply vehicle can be used. However, extending the cable length inevitably increases the weight of the cable and causes inconvenience. In addition, the noise from the diesel engine of the fuel-powered power supply vehicle can affect aircraft maintenance, and the exhaust fumes are also harmful to the health of ground crew. 2. For some repair hangars where the power distribution network is already fixed, the power supply can be improved by modifying the power distribution network, but the economic cost is high and the feasibility is low.
