The power box wire hole structure of the utility model only needs to open the maintenance box in maintenance operation, leads out the power line from the wire hole, connects the power line with the power supply, closes the box door, and continues the maintenance operation; the potential safety hazard caused by opening the box door of the maintenance power box for a long time is avoided, and after the maintenance operation is finished, the box door is opened again, the power line is dismantled, and the box door is closed; the wire outlet hole is sealed by the plug cover, so that rainwater and moisture are prevented from entering the box body along the wire outlet hole, and the safe operation of the maintenance power box is prevented from being influenced.
Description
Technical Field
The utility model belongs to the technical field of the power supply box, a transformer substation overhauls power supply box wire hole structure is related to.
Background
According to the on-site investigation, in the process of maintenance operation, a maintenance power box needs to be opened, a required power line is led out, the power line can be dismantled until the maintenance operation is finished, and a box door is closed. In the whole maintenance operation process, the maintenance power box is required to be kept in an open state all the time, and if severe weather occurs, rainwater, wind, snow and the like can influence the safe operation of the maintenance power box, so that potential safety hazards are brought to the maintenance operation; the door of the maintenance box is always kept open, so that the misoperation of elements in the maintenance box is easily caused, and the reliable operation of the maintenance power box is influenced; if the maintenance power box is frequently opened for use, the service life of the electrical elements in the box body is greatly reduced, the operation and maintenance cost is increased, and the box body is provided with the threading holes and cannot be sealed perfectly.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the utility model provides a transformer substation overhauls power supply box wire hole structure to solve the problem that exists among the prior art.
The utility model discloses the technical scheme who takes does: the utility model provides a transformer substation overhauls power supply box wire hole structure, includes sleeve pipe, blanking cover and lock nut, and the sleeve pipe outer column face is close to the middle part and is provided with hexagonal head, and the inner adopts lock nut locking behind the sleeve pipe insertion power supply box's the wire hole, and the blanking cover shutoff is in the sleeve pipe outer end.
Preferably, the blocking cover is fixedly connected to the sleeve in a threaded portion mode, and a first sealing ring is arranged at the joint of the blocking cover.
Preferably, the hexagonal head is located on the outer side surface of the power box, and a second sealing ring is arranged between the hexagonal head and the outer side surface.
Preferably, a hanging ring is arranged on the hexagonal head and connected to the power box through a bolting pull rope.
The utility model has the advantages that: compared with the prior art, the power box wire outlet hole structure of the utility model only needs to open the maintenance box, lead out the power wire from the wire outlet hole, connect the power wire to the power supply, close the box door and continue the maintenance operation; the potential safety hazard caused by opening the box door of the maintenance power box for a long time is avoided, and after the maintenance operation is finished, the box door is opened again, the power line is dismantled, and the box door is closed; the wire outlet hole is sealed by using the plug cover, so that rainwater and moisture are prevented from entering the box body along the wire outlet hole, and the safe operation of the overhaul power box is prevented from being influenced; and the wire outlet hole blocking cover is hung near the wire outlet hole by using a pull rope, so that the wire outlet hole blocking cover is prevented from being lost carelessly in the process of maintenance operation.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic diagram of the right-side structure of the present invention;
fig. 3 is a left side view structure diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example 1: as shown in fig. 1-3, a substation maintenance power box wire hole structure comprises a sleeve 1, a blocking cover 2 and a locking nut 3, wherein a hexagonal head 6 is arranged on the outer cylindrical surface of the sleeve 1 near the middle part, the inner end of the sleeve 1 is locked by the locking nut 3 after being inserted into a wire hole of a power box 4, and the blocking cover 2 blocks the outer end of the sleeve 1.
Preferably, the blocking cover 2 is fixedly connected to the sleeve 1 by a thread part, and a first sealing ring 7 is arranged at the joint of the blocking cover 2.
Preferably, the hexagonal head 6 is located on the outer side surface of the power box 4, and a second sealing ring 8 is arranged between the hexagonal head and the outer side surface.
Preferably, the hexagonal head 6 is provided with a hanging ring 5, and the hanging ring 5 is connected to the power box 4 through a bolt pull rope.
The sleeve 1, the blanking cover 2 and the locking nut 3 of the wire outlet hole are made of stainless steel, so that the occurrence of corrosion and damage in the use process is avoided, and the service life of the sleeve and the service life of the box are the same as that of the box
Installing a wire outlet hole on the side surface of the maintenance power box, and in maintenance operation, only opening the maintenance box, leading out a power wire from the wire outlet hole, connecting the power wire to a power supply, closing the box door, and continuing maintenance operation; the potential safety hazard caused by opening the box door of the maintenance power box for a long time is avoided. After the maintenance operation is finished, opening the box door again, detaching the power line and closing the box door; the special plug is used for sealing the wire outlet hole, so that rainwater and moisture are prevented from entering the box body along the wire outlet hole, and the safe operation of the overhaul power box is prevented from being influenced; in addition, the special plug for the wire outlet hole is hung on the wire outlet hole by using a stainless steel chain, so that the special plug is prevented from being lost carelessly in the process of maintenance operation.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention, therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
