Abstract

The utility model discloses a power supply box for substation power maintenance, which comprises a power supply box shell. The power supply box shell is provided with a cable hole, a rainproof cover is arranged outside the cable hole, and a movable baffle is arranged inside the cable hole. Since the utility model is provided with a cable hole in the power supply box shell, when the cable is connected, the cable hole of the substation power maintenance power supply box casing penetrates into the power maintenance power supply box, and the power supply box door of the substation power maintenance can be closed normally, which effectively solves the problem. In order to solve the problem that the power supply box of the substation power maintenance is not tightly closed during use, a rainproof cover is installed outside the cable hole to prevent the short circuit or grounding of the AC low voltage system caused by the immersion of foreign objects or rainwater. After use, remove the cable, close the movable baffle, and set a rubber ring inside the cable hole, thereby preventing the short circuit or grounding of the AC low-voltage system caused by the immersion of foreign objects or rainwater, and avoiding potential safety hazards.

Description

Power supply box for substation power maintenance

technical field

The utility model belongs to the technical field of electric power maintenance equipment, in particular to a power supply box for substation power maintenance. the

Background technique

In the power system, several power supply boxes are usually installed in the outdoor high-voltage equipment area of the substation for use in equipment maintenance. However, due to structural factors, the power supply box currently used cannot be closed after being connected to the maintenance power supply cable, and cannot prevent the short circuit or grounding of the AC low-voltage system caused by rainwater invasion, small animal invasion, and foreign matter invasion. Security risks. the

Utility model content

The utility model provides a substation power maintenance power supply box with simple structure, low cost, increased safety factor and easier operation. the

A substation power maintenance power supply box includes a power supply box shell, a cable hole is set on the power box shell, a rainproof cover is set outside the cable hole, and a movable baffle is set inside the cable hole. the

A rubber ring is arranged inside the cable hole. the

The rainproof cover is welded to the housing of the power supply box. the

Because the utility model is provided with cable holes in the power box housing, the outside of the cable hole is provided with a rain cover, the inside of the cable hole is provided with a rubber ring, and the inside of the cable hole is provided with a movable baffle. When the cable is connected, the cable hole outside the substation power maintenance power box penetrates into the power maintenance power box, and the door of the substation power maintenance power box can be closed normally, which effectively solves the problem that the substation power maintenance power box is not tightly closed during use. A rain-proof cover is set outside the cable hole to prevent short-circuit or grounding of the AC low-voltage system caused by the intrusion of foreign objects or rainwater, avoiding potential safety hazards, ensuring the safe operation of the low-voltage power supply, and increasing the safety factor. After use, remove the cable, close the movable baffle, and set a rubber ring inside the cable hole, thereby preventing the short circuit or grounding of the AC low-voltage system caused by the intrusion of foreign objects or rainwater, and avoiding potential safety hazards. the

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described:

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

Detailed ways

As shown in Figure 1: a substation power maintenance power box, including a power box housing 1, the power box housing is provided with a cable hole 2, the inside of the cable hole 2 is provided with a rubber ring 3, and the outside of the cable hole 2 is provided with an anti-corrosion A rain cover 5, a movable baffle 4 is arranged inside the cable hole 2. the

Since the utility model is provided with a cable hole 2 in the power box housing 1, and a rubber ring 3 is arranged inside the cable hole 2, when the cable is connected, it penetrates into the power maintenance power box from the cable hole 2 of the power box shell, and the power box door It can be closed normally, which effectively solves the problem that the power supply box of the substation power maintenance is not tightly closed during use. The rainproof cover 5 is installed outside the cable hole 2, which prevents the short circuit or grounding of the AC low-voltage system caused by the immersion of foreign objects or rainwater, and avoids the occurrence of potential safety hazards. , to ensure the safe operation of the low-voltage power supply, increasing the safety factor. After use, the cable is removed, the movable baffle 4 is closed, and the inner side of the cable hole 2 is provided with a rubber ring, thereby preventing short circuit or grounding of the AC low-voltage system caused by foreign matter or rainwater, and avoiding potential safety hazards. the
