AI Technical Summary

Technical Problem

In existing breathers for oil-immersed transformers, the water saturation of color-changing silica gel is not accurately determined, and the water-absorbing particles are prone to freezing and sticking together, blocking the pores, affecting the oil level adjustment, and causing the oil to become damp and the dielectric strength to decrease.

Method used

A water absorption box structure with multiple drying chambers is designed. The drying chambers are used alternately by rotating the water absorption box. When the water-absorbing particles are saturated, a hot air component is used for drying. Hydrophobic materials are used to treat condensed water droplets to ensure oil level regulation and water absorption effect.

Benefits of technology

It extends the service life of the respirator, ensures stable adjustment of the oil level, prevents the oil from getting damp, improves dielectric strength, saves energy, and enables the reuse of water-absorbing particles.

Abstract

The invention discloses an oil-immersed transformer convenient to replace insulating oil, and relates to the technical field of oil-immersed transformers, the oil-immersed transformer comprises a transformer main body, cooling fins are arranged on the peripheral surface of the transformer main body, an oil conservator is fixedly connected to one side of the upper surface of the transformer main body, and an air bag is arranged in the oil conservator; the end, extending out of the conservator through the second guide pipe, of the air bag communicates with a respirator. When water absorption particles in one drying cavity absorb water to be saturated or agglomerate and the like, the water absorption box rotates in the connecting shell, the next drying cavity communicates with the second guide pipe, the second connecting pipe, the air bag and the external environment, the working time of the respirator can be prolonged through the arrangement of the multiple drying cavities, and the service life of the respirator is prolonged. And when air holes of one drying cavity are blocked, the next standby drying cavity still exists, and it is guaranteed that adjustment of the height of the oil level in the oil tank is not affected.
