Pipe reinforcement device of the present invention for achieving the above object, the first pipe extends to the insulating oil tank sequentially installed in the transformer, and the second pipe extends to the radiator, the end of the first and second pipes Fixing the first and second plates having first and second fastening holes in the part, while the first and second plates surround the first and second plates while forming fastening holes corresponding to the first and second fastening holes. It is configured to combine the reinforcing member to protect the insulating oil leakage.

The reinforcing member may further include a first reinforcing bar surrounding the first pipe and a second reinforcing bar surrounding the second pipe, and the fastening holes may be positioned on the same line as the first and second fastening holes to fasten the fastening members. It is configured to be formed on each of the first and second reinforcement to be made.

In addition, the first and second reinforcing bars are in close contact with the outer circumferential surfaces of the first and second pipes to extend the first and second pipe guards for reinforcing strength of the first and second pipes, respectively.

As described above, the present invention is to install the reinforcing rod in the first and second pipes of the insulating oil tank and the radiator, thereby preventing the leakage of the insulating oil flowing through the pipe while reinforcing the strength of the connection portion of the first and second pipes You can expect the effect of improving the quality satisfaction for.

3 to 6, the pipe reinforcement apparatus of the transformer according to the embodiment of the present invention may include the first pipe 11a in the insulating oil tank 11 and the radiator 12 sequentially installed in the transformer 100, respectively. ) And the second pipe 12a, and the first and second plates 13 having first and second fastening holes 13a and 14a at end portions of the first and second pipes 11a and 12a. In fixing the 14), the reinforcing member 20 is coupled to the first and second plates 13 and 14.

That is, the reinforcing member 20 is to protect the leakage of the insulating oil flowing through the first and second pipes (11a, 12a) while wrapping the first and second plates (13, 14), The first and second reinforcing rods 21 and 22 are included.

The first reinforcement 21 is configured to surround the first pipe 11a, and the second reinforcement 22 is configured to surround the second pipe 12a. The first and second reinforcement 21 22) are formed on the same line as the first and second fastening holes 13a and 14a, respectively, to form fastening holes 20a for guiding to be coupled through fastening of the fastening members 15.

At this time, the first and second reinforcing rods 21 and 22 are in close contact with the outer circumferential surface of the first and second pipes 11a and 12a to reinforce the strength of the first and second pipes 11a and 12a. The first and second pipe guards 23 and 24 were configured to extend, respectively.

As such, the present invention, as shown in Figures 3 to 6 attached, first to combine the first reinforcing rod 21 included in the reinforcing member 20 to the outer peripheral surface of the first pipe (11a) of the insulating oil tank (1) The second reinforcing rod 22 included in the reinforcing member 20 is coupled to the outer circumferential surface of the second pipe 12a of the radiator 12.

Thereafter, in the state where the first and second plates 13 and 14 are fixed to the ends of the first and second pipes 11a and 12a by welding, the first and second plates 13 and 14 are connected to the first and second plates 13 and 14. The first and second plates 13 and 14 are brought into close contact with each other while the positions of the first and second fastening holes 13a and 14a to be formed are positioned on the same line.

Next, the first and second reinforcing bars 21 and 22 are brought into close contact with the first and second plates 13 and 14, and then the direction of the fastening hole 20a formed in the first reinforcing bars 21. After passing through the bolt of the fastening member 15 in the direction of the first and second fastening holes 13a, 14a and the second reinforcing table 22 formed in the first and second plates 13 and 14, The nut is tightened by fastening the nut of the fastening member 15 to the bolt.

Then, from the tightening operation of the fastening member 15, the first and second plates 13 and 14 are protected by being wrapped by the first and second reinforcing rods 21 and 22, as well as the first. The pipe guards 23 and 24 extending from the second reinforcing rods 21 and 22 surround the outer circumferential surfaces of the first and second pipes 11a and 12a, and the first and second pipes 11a and 12a. As the coupling portion of) increases, the coupling strength is reinforced, and accordingly, leakage of insulating oil can be prevented at the connection portions of the first and second pipes 11a and 12a.
