Description

Conductive rod

technical field

The invention relates to a power accessory, in particular to a conductive rod.

Background technique

The power supply department must remove the nut on the conductive rod of the transformer when overhauling and repairing the transformer of the 10 kV distribution line. Since the conductive rod of the distribution transformer is cylindrical, it is not easy to fix the conductive rod with tools during disassembly. , so as to rotate together with the nut; at the same time, when the transformer load is too large, the transformer nut and the conductive rod will be slightly welded together due to the phenomenon of firing and sintering, which further makes the conductive rod rotate together with the nut when the nut is disassembled, and the The lower end of the conductive rod and the low-voltage winding in the transformer box are crimped by multi-layer soft copper sheets and screws. The rotation of the conductive rod will displace the soft copper sheets and twist them into twists, resulting in poor contact between the conductive rod and the low-voltage coil. Therefore, in actual maintenance, two maintenance personnel are often required to climb on the transformer stand at the same time, one person fixes the conductive rod, and the other tightens the nut; it is impossible to use a hacksaw to saw it off. Due to the limited operating space on the transformer stand, the work is time-consuming Increased effort and danger.

In order to solve the above existing problems, people have been seeking an ideal technical solution.

detailed description

The technical solutions of the present invention will be described in further detail below through specific implementation methods.

Example 1

As shown in Figure 1, a conductive rod includes a conductive rod body, the conductive rod body includes a threaded rod one 3, a connecting rod 2, a threaded rod two 1 and a square rod 4, the threaded rod one 3 and the threaded rod one One end of the rod two 1 is detachably connected to both ends of the connecting rod 2 respectively, and the other end of the threaded rod two 1 is fixedly connected to the square rod 4 .

The diameter of described threaded rod one 3, described threaded rod two 1 and described connecting rod 2 is 20mm, and the length of described square rod 4 is 12mm, and the cross section of described square rod 4 is a square, and described square rod 4 The side length is 14mm.

This method of making one end of the conductive rod into a rectangle enables maintenance personnel to easily fix it with a tool when disassembling the conductive rod, and then disassemble the nut with a wrench, which effectively solves the problem of the connection between the conductive rod and the nut. The problem of rotation; adding a strip-shaped groove at the end of the square rod 4 facilitates the staff to identify whether the conductive rod is separated from the nut.

Due to the limited operating space on the transformer stand, when dismounting the transformer nut, the threaded rod 2 1 can also be disassembled from the connecting rod 2 first, and then the transformer nut can be disassembled from the threaded rod 2 1; Or directly replace the new screw rod II 1 and the transformer nut.

Example 2

The difference between this embodiment and Embodiment 1 is that: as shown in FIG. 1 , the threaded rod 3 and the connecting rod 2 are both hollow structures, and the connecting rod 2 is densely covered with ventilation holes 5 .

The fundamental reason why the conductive rod will rotate with the nut during disassembly is that the transformer nut and the conductive rod are slightly welded together due to the phenomenon of firing and sintering due to excessive load; after adopting the technical solution of this embodiment, the hollow structure and The setting of the ventilation hole increases the contact area between the conductive rod and the air, reduces the temperature of the conductive rod, reduces the phenomenon that the nut and the conductive rod are welded together, and fundamentally alleviates the problem of the conductive rod The problem with turning with the nut.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the present invention can still be Modifications to the specific implementation of the invention or equivalent replacement of some technical features; without departing from the spirit of the technical solution of the present invention, should be included in the scope of the technical solution claimed in the present invention.
