Mobile power box facilitating cable replacement

Abstract

The invention belongs to power transmission and transformation tools of the power industry, and particularly relates to a mobile power box facilitating cable replacement. The mobile power box facilitating cable replacement comprises a power box shell (24), a handlebar (26), a walking wheel shaft frame (9), walking wheel shafts (10), walking wheels (11) and binding posts (1) and is characterized inthat a trolley is arranged above the inner bottom face of the power box shell (24), a cable wire shaft (7) is arranged on the periphery of an inserting shaft (8-1), a lower movable door (16) is arranged on the bottom face end of the left side of the power box shell through a fold (20), an upper movable door (19) is arranged on a left side panel of the power box shell through a fold (20), a binding connector assembly (21) is fixedly arranged at the position, in the power box shell, above the upper movable door in a left and right correspondence manner, a wire shaft (23) is fixedly arranged atthe position, on the left side face and the right side face in the power box shell, above the binding connector assembly (21), and a cable baffle (5) is arranged in front of a wire outlet (24-1). Themobile power box facilitating cable replacement can be used under various complex site environments, is flexible and convenient to move and has the reliable overload protection and earth leakage protection functions, and the mobile power box can be used for electric appliances with unstable large-capacity current and some special tests. A cable shaft passes through the trolley, and work efficiencyis improved.

Description

technical field [0001] The invention belongs to tools for power transmission and transformation in the electric power industry, and in particular relates to a mobile power supply box which is convenient for replacing cables. Background technique [0002] At present, in the power transmission and transformation construction work in the power industry, there are two general temporary power supply devices used. One is the iron sheet cable reel. Although it is more convenient to carry, it can only be used for AC 220V power supply, and because the cable During work, the cables on the cable reel must be unfolded regardless of the distance, otherwise, the unexpanded cables and the cable shaft made of iron sheet will generate eddy currents during use, which will cause the cables to heat up, and the cable insulation will be damaged for a long time. The second is the self-made power board, which is made of epoxy resin, safe and reliable, and can be applied to AC 380V and 220V, but thi...

Problems solved by technology

[0002] At present, in the power transmission and transformation construction operations in the power industry, there are two general temporary power supply devices used. One is the iron sheet cable reel. During work, no matter the distance, the cables on the cable reel must be unfolded, otherwise, the unexpanded cables and the cable shafts made of iron sheets will generate eddy currents during use, which will cause the cables to heat up, and the cable insulation will be damaged for a long time. The second is the self-made power board, which is made of epoxy resin, which is safe and reliable, and can be applied to AC 380V and 220V, but this power board is heavy, inconvenient to carry and move, and has low work efficiency , especially in large-scale and complex operations, such as the construction of new and renovated substations, due to the complex environment of the construction site, many operators, many electrical equipment, flow, repetition, and strong temporary nature, there are many potential safety hazards

In addition, it is very inconvenient to replace the cable shaft in the existing mobile power box, which is labor-intensive and time-consuming, which affects work efficiency
