Transformer respirator silicone replacement device

Abstract

The invention belongs to the field of transformer assisting equipment and particularly relates to a transformer respirator silicone replacement device. The installation structure of an existing respirator is utilized fully, the respirator is toppled over through a reversible structure to have silicone replaced, the respirator and the replacement device are fixed on an original installation base ofthe respirator during operation, the situation that the respirator is disassembled and moved is not needed, small space occupation is achieved, operation content can be reduced, the respirator is ascended and descended by the aid of an airbag, stress gradient during operation is achieved, damage to the respirator in structure is avoided, a metal seat at the lower end of the respirator is clampedthrough a respirator fixing seat, and the upper end of the respirator is supported through a buffer sleeve. The transformer respiration silicone replacement device is simple in structure and rapid inoperation, extra operation space is not needed, silicon replacement efficiency can be effectively improved, and the effects are better especially in situations that the installation position of the transformer respirator is high, nearby structure is complex and assembling and handling are inconvenient.

Description

technical field [0001] The invention belongs to the field of auxiliary equipment for transformers, and in particular relates to a silica gel replacement device for a transformer respirator. Background technique [0002] Transformer breather is a necessary supporting device for 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. Existing transformer respirators are hoisted on the outside of transformers or other structures through breathing tubes. Transformer respirators require regular maintenance and replacement of the silicone inside. Due to the structural characteristics of the respirator, the respirator needs to be disassembled from the breathing tube Fill the new silica gel after the used silica gel is discharged. Since the shell of the middle part of the respirator i...

Problems solved by technology

Existing transformer respirators are hoisted on the outside of transformers or other structures through breathing tubes. Transformer respirators require regular maintenance and replacement of the silicone inside. Due to the structural characteristics of the respirator, the respirator needs to be disassembled from the breathing tube Fill the new silica gel after the used silica gel is discharged. Since the shell of the middle part of the respirator is usually a glass structure, the operation process needs to be handled with care. With the use of various high-voltage transformers and other large transformers, the volume of the respirator and The weight becomes very large. At the same time, some transformers are limited by the installation space or the use environment. The small operating space near the respirator makes it impossible to complete the replacement and maintenance work efficiently and conveniently, especially for some respirators located at higher positions. There is a high risk in the process, not only the respirator needs to be dismantled and transported to the ground for filling, but also the silicone cylinder must be vertically upward during the transport process to avoid silicone spills, which is very inconvenient to carry up and down
