Manufacturing method of protective jacket for protecting respirator

Abstract

The invention discloses a method for making a respirator protective cover, which includes the following steps: A: Prepare a waterproof cloth and a double-headed zipper, cut the waterproof cloth into two equal-sized rectangles, and then spread a waterproof cloth between the two waterproof cloths. Polyethylene foamed cotton, use sealant to fix polyethylene foamed cotton and two waterproof cloths, and then use silk thread to sew the edges of the waterproof cloths in turn to complete the production of the protective cover body; B: open a liquid level on the protective cover body Observation port, and suture the surroundings of the liquid level observation port with silk thread; C: Then fix the two side cloths of the double-ended zipper and the two ends of the sewn protective cover body respectively, when the double-ended zipper is sealed and locked, the The protective cover body forms a sleeve. The invention solves the problem that external water vapor easily enters the respirator through the cracks when the glass is shaken and cracks are generated.

Description

technical field [0001] The invention relates to the technical field of transformer maintenance, in particular to a manufacturing method for a respirator protective cover. Background technique [0002] Transformer respirator is also called transformer moisture absorber, or transformer silica gel tank, transformer desiccant, and is generally installed at the end of the pipeline where the oil conservator communicates with the air. A common transformer respirator is mainly composed of an iron pipe, a glass container and an oil cup, with a desiccant inside, and a certain amount of insulating oil in the oil cup. Its function is to absorb the moisture in the air entering the oil pillow plastic bag and diaphragm, remove and dry the sundries and moisture in the air entering the transformer or oil conservator due to the change of transformer oil temperature, so as to prevent the transformer from being damp and ensure the transformer oil dielectric strength. [0003] In order to faci...

AI Technical Summary

Problems solved by technology

[0003] In order to facilitate observation, most of the structure of the transformer respirator is made of glass, but the glass is prone to shocks and cracks, and the cracks are generally small and difficult to observe. External water vapor can easily enter the respirator through the gap, resulting in desiccant Susceptible to premature failure, resulting in frequent replacement of the desiccant in the respirator
