Description

technical field

[0001] The invention relates to a portable rotary switch box used on a shipbuilding platform, belonging to the shipbuilding industry. Background technique

[0002] On the shipbuilding platform, in order to meet the needs of the shipbuilders to use power, there are many scattered fixed power switch boxes on the shipbuilding platform. Because the workers on the shipbuilding platform have a lot of random requirements for the power switch boxes, the fixed power switch boxes cannot meet The needs of shipbuilders for power supply are changed into many movable power switch boxes, and multiple power switches are set in each mobile power switch box. When the area where workers use power is determined, the movable power switch boxes are placed After the central position of the area, connect the external power supply to each power switch in the switch box, and then distribute the power to each user through each power switch. In order to ensure the heat dissipation of th...
