Transformer respirator with optimized structure

Abstract

The invention discloses a transformer respirator with an optimized structure. The transformer respirator comprises a conical upper end cover and a circular lower end cover, a vertical eccentric shaftis fixed on the upper end surface of the lower end cover, the upper end of the eccentric shaft is inserted and fixed on the upper end cover, an upper flanging and a lower flanging are respectively formed at the lower end of the upper end cover and the upper end edge of the lower end cover, an annular silica gel outer cover is inserted between the upper flanging of the upper end cover and the lowerflanging of the lower end cover, and the upper end and the lower end of a silica gel outer cover are respectively abutted against the upper flanging of the upper end cover and the lower flanging of the lower end cover; a plurality of horizontal limiting rods are fixed in the silica gel outer cover, the eccentric shaft is inserted into the limiting rods, arc-shaped necks are formed in the side walls of the limiting rods, and the center shaft is connected into the necks of the limiting rods in a clamped mode. The structure of an existing respirator is rectified, when allochroic silicagel in therespirator is replaced, the respirator does not need to be detached, and replacement operation of the allochroic silicagel in the respirator is facilitated.

Description

Technical field: [0001] The invention relates to the technical field of oil-immersed transformers, in particular to a structurally optimized transformer respirator. Background technique: [0002] The basic structure of a transformer consists of a body, an oil tank, a cooling device, a protection device, an outlet device and transformer oil. The fuel tank includes the fuel tank body and accessories; the protection devices include oil pillows, oil gauges, safety airways, respirators, temperature measuring components, oil purifier relays, etc. Respirator, also known as moisture absorber, is filled with adsorbent inside. The adsorbent is often made of color-changing silica gel. Its function is to absorb moisture in the air and reduce the exposure and oxidation of transformer oil. The respirator is connected to the oil pillow through the pipeline. The current respirator is directly connected to the pipeline with bolts, and the color-changing silica gel in the respirator needs to...

AI Technical Summary

Problems solved by technology

The respirator is connected to the oil pillow through the pipeline. The current respirator is directly connected to the pipeline with bolts, and the color-changing silica gel in the respirator needs to be replaced after absorbing enough water. At present, the replacement of the discoloration silica gel needs to be removed from the pipeline. Respirator, and then disassemble the various parts of the respirator, such as disassembling the transformer oil cup, cutting the glass glue between the silicone cover and the connecting end cap, etc., it is cumbersome and troublesome to replace the color-changing silica gel, so it is necessary to facilitate the replacement of the color-changing silicone respirator
