Description
Technical Field
[0001] This utility model relates to the field of power equipment technology, and in particular to a temporary distribution box. Background Technology
[0002] As the core equipment for power distribution and control, the distribution box is designed to meet the needs of various electrical wiring. It carefully assembles switching equipment, measuring instruments, protective electrical appliances, and auxiliary equipment in a robust enclosed or semi-enclosed metal cabinet or panel, thus forming what we call a low-voltage distribution box.
[0003] During normal operation, staff can easily connect or disconnect circuits manually or automatically to ensure proper power distribution. When the system malfunctions or operates abnormally, the protective devices in the distribution box will quickly cut off the circuit or issue an alarm signal, effectively protecting the circuit and equipment. Simultaneously, high-precision measuring instruments allow for real-time display and monitoring of various key operating parameters, such as voltage and current, and enable necessary adjustments to certain electrical parameters. If these parameters deviate from normal operating conditions, the distribution box will immediately issue a warning or signal, prompting timely action.
[0004] In existing technologies, distribution boxes not only possess the advantages of small size and convenient installation, but are also widely popular due to their unique technical performance and configuration functions. They can operate stably and reliably in fixed locations, without site restrictions, making power distribution more flexible and efficient. Furthermore, distribution boxes are environmentally friendly; their high space utilization and small footprint have led to their widespread application in modern power systems. In addition, as the control center of the power supply line, the distribution box can reliably receive power from upstream sources while accurately feeding power to various load devices; it is a key link in ensuring that power supply quality meets user needs and is of great significance for improving the stability and reliability of the entire power system.
[0005] However, the inventors of this application have found that the existing technology has the following defects in actual construction practice: (1) The temporary distribution box at the construction site will be moved according to the specifications and actual use requirements of the site, and it is usually moved by personnel or mechanical equipment. Moreover, the moving and transporting are very time-consuming and laborious. (2) In the actual temporary power use process, when encountering unexpected situations such as sudden power outages or power failures, the construction personnel usually open the box door at the first time to check whether the circuit breaker has tripped without knowing the reason. Moreover, most of the construction personnel are not formal electricians, and most of the power connection and disconnection on site are also done by such personnel, which has laid a huge safety hazard for the safe use of electricity on site.
[0006] Therefore, how to provide a temporary power distribution box that can effectively improve the safety and ease of handling of power supply at construction sites has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0007] The purpose of this utility model is to provide a temporary power distribution box that can effectively improve the safety of temporary power supply at construction sites, reduce secondary handling, and facilitate transportation, thereby improving construction efficiency and ensuring good construction results.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] The enclosure is fitted with a partially penetrating shell below the door, and an insert-type automatic rebound socket is provided inside the space formed by the shell and the enclosure; a cable bracket is fitted on the back of the enclosure, and the cable bracket is used to connect a power cord reel.
[0011] The top of the box is connected to a rainproof canopy, and a handle is provided in the middle area of the top of the rainproof canopy; the bottom of the box is connected to a detachable bracket, and the bottom of the bracket is connected to casters.
[0012] In practical applications, the transparent cabinet door is made of PVC waterproof, corrosion-resistant and flame-retardant material.
[0013] The box door is equipped with a locking structure.
[0014] Specifically, there are two automatic rebound sockets.
[0015] Furthermore, the end of the power cord reel uses a dedicated cable connector, and during use, it is connected to the power cable of the upper-level temporary distribution box using a cable connector of the same model and specification.
[0016] Furthermore, the tilt angle of the rainproof canopy is 30°.
[0017] Furthermore, the handle is made of galvanized flat steel and welded to the rainproof canopy.
[0018] Furthermore, the bracket is connected to the bottom of the box by four bolts, and the side of the bracket has an A-shaped structure; four anti-corrosion stainless steel casters are welded to the bottom of the bracket, and each caster has a braking structure.
[0019] Compared with existing technologies, the temporary power distribution box described in this utility model has the following advantages:
[0020] The temporary power distribution box provided by this utility model has a transparent door. Inside the space formed by the door and the box body, there is a 100A residual current device (RCD) and two 32A RCDs.

Furthermore, a rainproof canopy is connected to the top of the box, and a handle is provided in the middle of the top of the rainproof canopy. The bottom is connected to a detachable bracket, and the bottom of the bracket is connected to casters. Therefore, by adding casters to the bottom of the bracket, adding a protective canopy and handle to the top of the box, and wrapping a power cord reel (about 1m long) around the back of the box, the technical problem of difficult transportation of temporary distribution boxes on site is effectively solved. In addition, by using a transparent door at the front, an external leakage protection switch, and an automatic rebound socket installed at the bottom of the distribution box, the problem of temporary power connection that cannot be operated by non-electricians on the construction site is effectively solved. The operation can be completed without disconnecting the power supply and cables, thereby effectively improving electrical safety, construction efficiency, and construction effect.
