Mobile temporary electricity construction power box

Abstract

The utility model relates to a mobile temporary electricity construction power supply box, which relates to a power supply box. At present, the temporary electricity is to directly pull the cable to connect the three-phase knife or to lead the power from the fixed power box to the construction electrical equipment from the power panel, which is unsafe and inconvenient. The invention includes a box body, a base arranged at the lower end of the box body, and a telescopic pull rod arranged at the back of the box body. The box body is provided with a knife, a leakage protector, a socket, a grounding copper bar and a grounding terminal, and the base is provided with a universal The wheel and two legs make the box both drag and stand. There is a wire reel on the back of the box, and the cable for dragging and dropping connected to the knife can be coiled on the reel; the other end of the knife is connected to the leakage protector through the connecting wire. One end is electrically connected, the other end of the leakage protector is electrically connected with the socket and the terminal, and the socket is also electrically connected with the neutral wire and the ground wire. The technical solution is convenient to operate, and improves the construction safety and the flexibility of use.

Description

technical field [0001] The invention relates to a power box. Background technique [0002] Temporary power consumption of construction equipment (such as electric welding machines, cutting machines, electronic instruments, etc.) at the construction site of the substation project is to directly pull the cable to connect the three-phase switch knife or use a power plate bought from the market to lead the power from the fixed power box to the For construction electrical equipment, the above two methods have defects: for example, it is not safe to directly connect the cable to the three-phase switch blade; There is no binding post, which does not meet the requirements of on-site construction, especially when the fixed power box is far away from the construction point, it is inconvenient to switch the power supply. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existi...
