Protective jacket for transformer respirator

Abstract

The invention discloses a protective jacket for a transformer respirator. The protective jacket for the transformer respirator comprises an upper tightly-wrapping piece and a lower tightly-wrapping piece arranged in parallel, wherein a plurality of connecting piece assemblies are perpendicularly arranged between the upper tightly-wrapping piece and the lower tightly-wrapping piece; the distance from the top end of the upper tightly-wrapping piece to the bottom end of the lower tightly-wrapping piece is more than the height of a glass cylinder of the transformer respirator; the length of the upper tightly-wrapping piece is less than the outer diameter of the glass cylinder; upper fixing holes are formed in the two ends of the upper tightly-wrapping piece correspondingly; a plastic buckle nail penetrates through the upper fixing holes to fasten the upper tightly-wrapping piece at the upper end of the glass cylinder; lower fixing holes are formed in the two ends of the lower tightly-wrapping piece correspondingly; a plastic buckle nail penetrates through the lower fixing holes to fasten the lower tightly-wrapping piece at the lower end of the glass cylinder. The protective jacket for the transformer respirator adopts a rubber elastic structure, can be used by being additionally arranged on most of the existing respirators without changing any structures of the original respirators, and adopts a structure of trisecting the glass cylinder to solve the unnecessary dispute between a maintenance unit and an overhaul unit on the color changing quantity of silica gel.

Description

technical field [0001] The invention belongs to the technical field of transformers in the electric power industry, and in particular relates to a protective cover for a transformer respirator. Background technique [0002] Respirator, also known as moisture absorber, is a safety protection device for oil-immersed power transformers. It is filled with adsorbents such as color-changing silica gel to absorb moisture that enters the plastic bags and diaphragms of the oil conservator in the air to ensure that it does not enter the oil conservator. air dry. At present, the sealing structure of most transformers and on-load pressure regulating breathing apparatus silicone tanks is: the upper and lower flanges are pressed tightly with the glass cylinder through the middle long screw rod, and the sealing ring is used to ensure the tightness of the tank body at the junction of the upper and lower flanges and the glass cylinder. . However, after the tank is exposed to the sun and ra...

AI Technical Summary

Problems solved by technology

However, after the tank is exposed to the sun and rain for a long time outdoors, the sealing ring is very easy to age and lose its elasticity, causing water vapor in the air to enter the tank and make the silica gel damp. It is necessary to replace the silica gel frequently to ensure the effectiveness of the respirator. Or remote towns, greatly increasing the workload of maintenance personnel

Transformer maintenance regulations stipulate that when the color-changing silica gel reaches 1 / 3, the on-duty personnel should notify the maintenance personnel to replace it. At present, there is no clear scale on the glass tube body of the respirator, which often causes operation and maintenance personnel and maintenance personnel to check whether the discoloration of silica gel exceeds the standard. A dispute occurred, so a technical solution was urgently needed on site to solve the above problems
