Silicone replacement device for transformer respirator

Abstract

The invention relates to the technical field of transformer respirator, and discloses a silica gel replacement device for a transformer respirator. The transformer respirator silicone replacement device includes a power module and a stirring module, the cover is detachably connected to the top of the housing, an accommodation cavity is formed between the cover and the housing, and the drive assembly is arranged on the In the accommodating chamber; the stirring module includes a helical stirring rod, one end of the helical agitating rod is detachably connected to the output end of the drive assembly, and the other end extends out of the accommodating chamber and is configured to extend into the transformer respirator Break up and export the silica gel particles. The silica gel replacement device for the transformer respirator enables smooth unloading of silica gel, improves the efficiency of silica gel replacement, and saves labor costs.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a silicone rubber replacement device for a transformer respirator. Background technique [0002] Transformer respirator is a supporting device on various oil-immersed transformers and other equipment. It is used to ensure the purity of the internal structure of the transformer, including the transformer oil, and to isolate impurities such as external air from entering the interior of the transformer. [0003] The existing transformer respirator is hoisted on the outside of the transformer or other structures through a breathing tube. The transformer respirator requires regular maintenance and replacement of the internal silicone. Shortcomings such as long replacement time make the work efficiency not high; and due to the structure of the respirator itself, the entire respirator needs to be disassembled during the silicone replacement process, which may cause moisture to ente...

AI Technical Summary

Problems solved by technology

[0003] The existing transformer respirator is hoisted on the outside of the transformer or other structures through a breathing tube. The transformer respirator requires regular maintenance and replacement of the internal silicone. Shortcomings such as long replacement time make the work efficiency not high; and due to the structure of the respirator itself, the entire respirator needs to be disassembled during the silicone replacement process, which may cause moisture to enter the transformer oil and cause insulation aging, which is not conducive to the safe operation of the equipment

[0004] Although some dismantling-free respirators have been applied in the field at this stage, in actual use, the silica gel particles inside the respirator will be adhered and hardened due to moisture absorption and deterioration, resulting in the cutting of the lower part of the respirator. The mouth cannot be automatically and smoothly unloaded after opening, and the site needs to use tools to manually dredge it to facilitate unloading

However, as large transformers such as various high-voltage transformers are put into use, the volume of the respirator increases, and the total amount of silica gel that needs to be replaced each time increases, resulting in longer replacement time. At the same time, the manual dredging process will also consume too much manpower and time cost
