Abstract
The invention provides a movable type power supply box for temporary electricity utilization construction and relates to a power supply box. Currently, temporary electricity utilization is realized by directly pulling a cable to be connected with a three-phase switch blade or leading a power supply to construction electricity utilization equipment by a power supply disc from a fixed power supply box, so that the temporary electricity utilization is not safe and not convenient. The movable type power supply box comprises a box body, a base arranged at the lower end of the box body and a retractable pull rod arranged on the rear face of the box body, wherein the box body is internally provided with a switch blade, a current leakage protector, a socket, a grounded copper bar and a grounded terminal; the base is provided with universal wheels and two supporting legs so that the box body can be pulled and can also stand; a coil disc is arranged on the rear face of the box body; a cable which is connected with the switch blade and is used for pulling can be wound on the coil disc; the other end of the switch blade is electrically connected with the current leakage protector by a lead wire; the other end of the current leakage protector is electrically connected with the socket and a binding post; the socket is further electrically connected with a null wire and a grounded wire; the base is a conductor; the grounded wire is electrically connected with the base after passing through the grounded terminal and the grounded copper bar. According to the technical scheme, the movable type power supply box is convenient to operate; the construction safety is improved and the use flexibility is improved.
Description
Technical field
The present invention relates to a kind of power supply box.

As the further of technique scheme improved and supplement, the present invention also comprises following additional technical feature.
The bottom surface of described casing is offered for wearing the wire guide of cable and earth connection.
Described casing comprise the rectangle storage case, with the chamber door of storage case switching, described chamber door is positioned at the front side of storage case with the sealing storage case, establishes door lock on case lid; The storage case bottom is provided with insulation board, and described plug-in strip, earth leakage protective device, socket, grounding copper bar all are located on insulation board; Described casing coated insulation layer.Insulating layer coating can be insulating varnish etc.
Beneficial effect:
1, the technical program makes every power consumption equipment be equipped with special-purpose separately power supply box, and be furnished with special-purpose plug-in strip and earth leakage protective device, make near the place of power supply control point convenient operation temporary electricity equipment simultaneously, while preventing that power line is dilatory and stressed, easy to operate, standard the construction temporary electricity, improved working security;
2, ground protection further improves the fail safe of equipment electricity consumption.
3 and this construction power supply case need move the time, hold pull bar casing tilted, rolls power supply box integral body is moved ahead by universal wheel, drag laborsaving, facilitate.
4, drum moves with casing, is convenient to the cable drag and drop, effectively increases work efficiency.
5, set up binding post, improve the flexibility of using.
