Dry-type transformer with shock-absorbing mounting base

By using a dry-type transformer with a vibration-damping mounting base, high-frequency vibrations are absorbed through a rubber sleeve and drive screw structure. Combined with vibration-damping springs and hydraulic dampers, multi-stage vibration reduction is achieved throughout the entire path, solving the problem of vibration transmission in dry-type transformers and significantly extending service life and structural stability.

AI Technical Summary

⚠Technical Problem

During operation, existing dry-type transformers directly transmit vibration energy between the transformer and the mounting base, leading to problems such as loose bolts, fatigue cracks in the mounting plate, and wear of the positioning mechanism. Existing vibration reduction solutions have failed to effectively address the high-frequency impacts and stress concentrations at the connection between the transformer base and the mounting mechanism.

⚗Method used

The dry-type transformer with a vibration-damping mounting base includes a four-corner positioning mechanism, a clamping mechanism, a mounting mechanism, and a vibration-damping mechanism. It absorbs high-frequency vibrations through rubber sleeves, avoids stress concentration by using the linkage structure of the drive screw and drive tube, and achieves multi-level vibration reduction throughout the entire path by combining vibration-damping springs, hydraulic shock absorbers, and buffer pads.

🎯Benefits of technology

It effectively absorbs high-frequency vibrations, reduces impact damage at connections, suppresses local vibration transmission, extends service life, reduces residual vibration energy at connecting bolts, and improves the vibration resistance and structural stability of the mounting frame.

Abstract

A dry-type transformer with a vibration-damping mounting base is disclosed. This invention relates to the field of power equipment technology. Several four-corner positioning mechanisms are respectively installed on the bottom of the dry-type transformer body; a clamping mechanism is located within the four-corner positioning mechanisms; an installation mechanism is located at the bottom of the four-corner positioning mechanisms; and a vibration-damping mechanism is located at the bottom of the installation mechanism. While achieving mechanical locking, it can effectively absorb high-frequency vibrations, significantly reduce impact damage at connections, avoid local stress concentration, and thus reduce the risk of fatigue damage. It can suppress the transmission of local vibrations from the bottom, reduce wear at the connection between the clamping plate and the transformer bottom, and extend the service life of critical contact surfaces. By constructing a multi-stage vibration-damping mechanism along the entire path, it significantly reduces residual vibration energy at the connecting bolts of various components, comprehensively improves the vibration resistance and structural stability of the mounting frame, and thus significantly extends the overall service life.
