Transformer Tank Mounting Seat for Support Fitting Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing transformer designs face challenges in efficiently attaching large support brackets to the sidewall of the tank, leading to increased assembly time due to the need for multiple beam connections, which prolongs the installation process of large transformers.
Innovation Solution
The design enhances the strength of the support fitting by enlarging its sectional area, allowing for the attachment of a larger support fitting in the height or width direction directly to the tank's peripheral wall, reducing the number of beams required and simplifying the assembly process through the use of mounting seats bonded to both the upper and middle tank peripheral walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a large support fitting is attached to the sidewall of the tank, then the strength of the support fitting is enhanced, but it becomes difficult to attach due to the presence of instruments and seams on the tank sidewall
Solution Approach 1:
The support structure is divided into two parts: a mounting seat that is bonded to the tank sidewall (avoiding instruments and seams) and a support fitting that is attached to the mounting seat. This segmentation allows the support fitting to be larger and stronger while the mounting seat handles the attachment complexity to the tank.
Solution Approach 2:
A mounting seat is introduced as an intermediary component between the tank sidewall and the support fitting. The mounting seat serves as a mediator that facilitates the attachment of the large support fitting to the tank without being constrained by the presence of instruments and seams on the tank sidewall.
2Strength
If many beam members are connected to the support fitting to secure necessary strength, then the strength requirement is met, but the assembling time of the transformer is lengthened
Solution Approach 1:
The support structure is segmented into a mounting seat and support fitting, where the mounting seat is pre-bonded to the tank during manufacturing. This allows the support fitting to be a single large component rather than multiple beam members, reducing assembly time at the installation location.
Solution Approach 2:
The design changes the structural parameters of the support fitting by using a single large-section component instead of multiple smaller beam members. This parameter change maintains the required strength while significantly reducing the number of connections and assembly time.

AI summary
A transformer includes a transformer body, a tank, a conservator, a plurality of support fittings, and at least one mounting seat. Transformer body includes an iron core and a winding. Tank includes an upper tank, a middle tank, and a lower tank that are bonded together to form an internal space accommodating transformer body. Conservator is arranged at a position above tank. The plurality of support fittings are arranged side by side at intervals to support conservator. At least one mounting seat is bonded to both a peripheral wall of upper tank and a peripheral wall of middle tank, and fixed to tank, and the plurality of support fittings are attached.
