Description

Connecting device for transformer oil pipeline

technical field

The utility model relates to a pipeline connection device, in particular to a connection device for a transformer oil pipeline.

Background technique

A transformer is an electrical device used to change an AC voltage of a certain value into another voltage with the same frequency or several different values. The connecting device of the transformer oil pipeline is used to connect the transformer oil pipeline in the transformer. During the installation process of the connection device of the transformer oil pipeline, due to the dimensional deviation of the alignment of the oil pipeline, the sealing ring will be squeezed and damaged during the fastening process, which will eventually lead to oil leakage of the transformer oil pipeline. Transformer oil is an important part of the transformer. It plays the role of insulation and cooling in the transformer. Oil leakage from the transformer will affect the safe and stable operation of the transformer in serious cases, and then threaten the safety of the power grid.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a connection device for a transformer oil pipeline that can solve the connection problem caused by interface errors caused by factors such as the size of the oil pipeline.

In order to achieve the above object, the utility model adopts the following technical solutions:

A connection device for a transformer oil pipeline, comprising an adjustable metal hose, the two ends of the adjustable metal hose are provided with adjustable pipe joints, the adjustable pipe joints include an inner sleeve and an outer sleeve, the inner sleeve One end of the sleeve is set in the outer sleeve, the other end of the inner sleeve is provided with a liner, the diameter of the liner is larger than the diameter of the inner sleeve, and a connecting flange is sleeved on the inner sleeve , the connecting flange is arranged between the liner and the outer casing. When the pipeline center line of the two sections of oil pipelines being connected deviates, the inner sleeve and outer sleeve of the adjustable pipe joint can be pulled to make each sleeve coaxial with the connected oil pipeline; when the connected oil pipeline When there is a deviation in the length of the pipe, the outer sleeve can be turned to change the length of the adjustable pipe joint to make up for the deviation; at the same time, the connecting flange can rotate around the adjustable pipe joint, which avoids the laborious situation of fastening during the interface docking process.

As a preferred technical solution of the utility model, the inner casing and the outer casing are threadedly connected.

As a preferred technical solution of the present invention, one end of the inner casing is provided with two annular sealing grooves, and an O-shaped sealing ring is arranged in the annular sealing grooves.

As a preferred technical solution of the present invention, the end of the outer casing is provided with a blocking cap.

Compared with the prior art, the beneficial effects achieved by the utility model are:

1. Effectively solve the difficult connection problem caused by the length and interface size error of the oil pipeline, and improve the success rate of one-time connection of the oil pipeline;

2. The connection process of the oil pipeline is easy and labor-saving, the sealing effect is good, and the adjustable metal hose has no force phenomenon.
