Description
Technical Field
The invention belongs to the technical field of transformer production and manufacturing, and particularly relates to a method for adjusting an inclination angle of a main air guide pipe of a transformer.
Background
In order to ensure the long-term safe operation of the transformer, gas accumulated in oil in each lifting seat at the top of the transformer must be led out so as to ensure the insulation strength of an inner lead wire of the transformer. The inner cavity of each lifting seat is communicated with a main air guide pipe by a branch air guide pipe, so that gas in oil in each lifting seat is led out through the main air guide pipe, the main air guide pipe is communicated with an oil storage cabinet, the main air guide pipe is obliquely arranged, a gas supply relay is arranged on the main air guide pipe, and if the inclination angle is insufficient, gas cannot smoothly escape and a gas trap phenomenon is generated.
When a manufacturer designs the inclination angle of the main air pipe, a certain included angle (generally 1.5% -2%) is usually formed between the design and the horizontal plane, but the main air pipe is generally manufactured without components due to the matching processing of parts with an assembly relation, and the second reason is that the components are not in stock during the assembly of the main air pipe, the components are expensive and easy to damage, only substitute parts are used for manufacturing, the weight of the substitute parts is light, the assembly between the connecting pipes is difficult, and other reasons are caused, so that the inclination angle is smaller than the assembly angle after the on-site installation. In recent years, due to the fact that the inclination angle of the main air pipe is insufficient, product acceptance is influenced, and the condition that a gas relay is subjected to light gas alarm due to long-term operation is rare.
In summary, those skilled in the art need to solve the above problems and to ensure that the angle of the main air pipe meets the requirements, a supporting structure of the main air pipe is added in a new project or an old project, and an inclination angle adjusting method of the main air pipe is found out without oil welding to ensure the operation and the service life of the transformer.
