Description

New Power Box

technical field

The utility model relates to electric equipment appliances, in particular to a novel power supply box.

Background technique

With the expansion of the grid scale, the maintenance site is becoming more and more complex, safe, reliable and convenient temporary power supply is an essential and important equipment for the maintenance site. As we all know, in the daily inspection and maintenance of substations, substation inspection power boxes are often used as external power supply points. And the power box has an inseparable electrical connection with the AC low-voltage system of the substation, and because it is often outdoors, if the protection is not good, it may affect the safe operation of the entire substation. The maintenance power supply box used in the existing substation needs to be equipped with a separate conductive cable, which is not only inconvenient to carry, but also requires on-site wiring every time it is used, which wastes time and reduces work efficiency. The door of the power box cannot be closed. If it encounters rain or snow or small animals get into the maintenance power box, it may cause short circuit or grounding of the internal wiring of the maintenance power box, which will cause great safety hazards to the safe operation of the power box and the maintenance of the substation.

In view of the above shortcomings, it is necessary to improve the existing power box to overcome the above shortcomings, ensure the safety of power supply, and improve the convenience of use.

Utility model content

In view of this, the purpose of this utility model is to provide a new type of power box, which can ensure that the door of the power box is closed during use, prevent rainwater or small animals from entering the power box, and ensure the safety of the power box.

The utility model solves the above-mentioned technical problems through the following technical means: a new type of power supply box, including a box body, a circuit breaker and a connecting terminal arranged in the box body, and an openable and closable box door is arranged on the box body, and the bottom of the box door has a The hinged way is provided with a reversible cover plate. The lower edge of the cover plate is provided with a plurality of upward arc-shaped holes that open downward. , the upper arc-shaped hole is aligned with the lower arc-shaped hole to form a plurality of circular line holes.

Further, a cable roller for winding wires is arranged in the box, and a wire cable is wound on the cable roller. One end of the conductive cable is electrically connected to the terminal in a detachable manner, and the other end is a free end connected to the power consumption equipment.

Further, a base is provided at the bottom of the box, and universal wheels are provided at the bottom of the base.

Beneficial effects of the utility model: the new power supply box of the utility model includes a box body, a circuit breaker and a connecting terminal arranged in the box body, and a box door that can be opened and closed is arranged on the box body, and the bottom of the box door is hinged. A reversible cover plate is provided. The lower edge of the cover plate is provided with a plurality of upward arc-shaped holes with openings downward. The arc holes are aligned with the lower arc holes to form a plurality of circular line holes. When in use, open the box door, connect the conductive cable to the terminal, and then put the conductive cable into a lower arc hole. After closing the box door, the conductive cable will pass through the wire hole without affecting the box door. To ensure that the door of the power box is closed, prevent rain or small animals from entering the power box, and ensure the safe use of the power box.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the structural representation of the utility model.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings, as shown in the figure: the new power supply box of this embodiment includes a box body 1, a circuit breaker 2 and a terminal 3 arranged in the box body, and the box body is provided with an openable and closed The box door 10, the bottom of the box door is provided with a reversible cover plate 9 in a hinged manner, the lower edge of the cover plate is provided with a plurality of upper arc-shaped holes 8 with openings downward, and the box body is located at the bottom of one side of the box door. The lower arc-shaped holes 5 with multiple openings upward, when the box door is closed, the upper arc-shaped holes 8 and the lower arc-shaped holes 5 are aligned to form a plurality of circular line holes. When in use, open the box door, connect the conductive cable to the terminal, and then put the conductive cable into a lower arc hole. After closing the box door, the conductive cable will pass through the wire hole without affecting the box door. To ensure that the door of the power box is closed, prevent rain or small animals from entering the power box, and ensure the safe use of the power box. Certainly, under the situation of not opening box door, also can only open cover plate 9 to carry out conductive cable connection, use is very convenient.

As a further improvement to the above technical solution, a cable roller 4 for winding wires is provided in the box, and a wire cable is wound on the cable roller. One end of the conductive cable is electrically connected to the terminal 3 in a detachable manner, and the other end is connected to the terminal 3. Free end of consumer. The power box has its own conductive cable, which is easy to receive and release, and the power supply and wire are integrated, which is easy to carry and quick to use. Moreover, different colors or models can also be used to distinguish, and a plurality of conductive cables are wound on the cable roller to meet multiple electricity demands at the same time.

As a further improvement to the above technical solution, a base 6 is provided at the bottom of the box, and universal wheels 7 are provided at the bottom of the base. Due to the heavy weight of the power supply box, universal wheels are provided to facilitate the handling of the power supply box, save labor, save manpower, and are convenient and quick to use.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation.
