Abstract
The utility model discloses a transformer station power maintenance power box comprising a power box housing, which is provided with cable hole. An outer side of the cable hole is provided with a rainproof cover, and an inner side of the cable hole is provided with a movable baffle plate. Because the cable hole is disposed in the power box housing, the cable is inserted in the power maintenance power box through the cable hole of the transformer station power maintenance power box housing, and the door of the transformer station power maintenance power box can be closed normally, therefore the problem of the transformer station power maintenance power box of incomplete seal can be effectively solved. The rainproof cover disposed on the outer side of the cable hole, therefore the short circuit or the grounding of the AC low voltage system caused by the intrusion of the foreign matters or the rainwater can be prevented. The cable can be taken down after use, the movable baffle plate can be closed, and the inner side of the cable hole is provided with a rubber ring, therefore the short circuit or the grounding of the AC low voltage system caused by the intrusion of the foreign matters or the rainwater can be prevented, and the occurrence of the safety hidden troubles can be prevented.
Description
Technical field
The utility model belongs to the electric power overhaul equipment technical field, particularly a kind of transformer station power maintenance power box.
Background technology
In electric power system, outside transformer substation high-tension apparatus district arranges several electrical source of power casees usually, in order to use during overhaul of the equipments.And present employed electrical source of power case is because structural factor, and after access maintenance power supply was with cable, chamber door can't seal, can't prevent because of the rainwater invasion and attack, the toy invasion and attack, foreign matter invasion and attack etc. cause short circuit or the ground connection of AC low-tension system, have many potential safety hazards.
The utility model content
The utility model provides a kind of simple in structure, cost is low, coefficient of safety increases, operation is easier a kind of transformer station power maintenance power box.
A kind of transformer station power maintenance power box comprises the power supply box housing, on this power supply box housing cable aperture is set, described cable aperture arranged outside rain cover, and described cable aperture inboard arranges sideboard.
Described cable aperture inboard arranges rubber ring.
Described rain cover and described power supply box housing are welded to connect.
Because the utility model arranges cable aperture at the power supply box housing, cable aperture arranged outside rain cover, the cable aperture inboard arranges rubber ring, and the cable aperture inboard arranges sideboard.During the cable access, pierce into the power maintenance power box from the cable aperture in the transformer station power maintenance power box outside, transformer station's power maintenance power box door can normally closed, effectively solved the problem of transformer station's power maintenance power box bad sealing in using, cable aperture arranged outside rain cover has prevented short circuit or ground connection that the immersions such as foreign matter or rainwater cause the AC low-tension system, has avoided the generation of potential safety hazard, guarantee the safe operation of low-tension supply, increased coefficient of safety.After use, take off cable, closed sideboard, the cable aperture inboard arranges rubber ring, thereby has prevented short circuit or ground connection that the immersions such as foreign matter or rainwater cause the AC low-tension system, has avoided the generation of potential safety hazard.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1: a kind of transformer station power maintenance power box, comprise power supply box housing 1, this power supply box housing arranges cable aperture 2, and described cable aperture 2 inboards arrange rubber ring 3, described cable aperture 2 arranged outside rain covers 5, described cable aperture 2 inboards arrange sideboard 4.
Because the utility model arranges cable aperture 2 at power supply box housing 1, cable aperture 2 inboards arrange rubber ring 3, during the cable access, pierce in the power maintenance power box from the cable aperture 2 of power supply box housing, the power supply chamber door can normally closed, effectively solve transformer station's power maintenance power box bad sealing problem in the use, cable aperture 2 arranged outside rain covers 5, short circuit or ground connection that the immersions such as foreign matter or rainwater cause the AC low-tension system have been prevented, avoided the generation of potential safety hazard, guarantee the safe operation of low-tension supply, increased coefficient of safety.After use, take off cable, sideboard 4 closures, cable aperture 2 inboards arrange rubber ring, thereby have prevented short circuit or ground connection that the immersions such as foreign matter or rainwater cause the AC low-tension system, have avoided the generation of potential safety hazard.
