Problems solved by technology

However, due to the large labor cost of disassembling and assembling the respirator, and the performance of the color-changing silica gel adsorbent after use is reduced, under comprehensive consideration, it is generally not used again, resulting in a low silica gel usage rate and high use and maintenance costs.
[0005] 2. The oil seal cup prevents dust from entering through the oil collection box at the bottom, but it needs to be cleaned regularly. If the cleaning is not thorough, the breathing channel will be blocked, causing the transformer to malfunction; if the silica gel is not replaced regularly, it may cause the silica gel to absorb water and eventually break. The broken powder It is likely to cause the hole of the respirator to be blocked, posing a safety hazard
[0006] 3. The color-changing silica gel adsorbent has toxic chemical components. At present, some units do not conduct centralized treatment of the discarded color-changing silica gel, and there is a great potential for environmental pollution.
[0007] 4. Although the overall structure of the respirator is simple, there are not many disassembly and assembly procedures, but because the respirator has high requirements for sealing, and due to the aging and rust of the connecting parts, and the transformer is generally located at a place with a high ground clearance location, so that there are not many disassembly and assembly procedures for the respirator, but the disassembly and assembly requirements are extremely high, and the disassembly and assembly workers are time-consuming and laborious, which often results in the overall scrapping of the respirator.

Abstract

The invention relates to a transformer respirator and a regeneration method of silica gel in the respirator. The transformer respirator comprises a silica gel bottle, an upper cover fixed to an upperend of the silica gel bottle and used for being connected with an oil conservator, a lower cover fixed to a lower end of the silica gel bottle and an oil seal cup fixed to a lower portion of the lowercover, the upper cover is provided with a plurality of vertically-through vent holes used for communicating the oil conservator with the silica gel bottle, a plurality of vertically oil through holescommunicated with the oil seal cup are formed in the lower cover, a hollow breathing tube is vertically arranged in the middle of the silica gel bottle, an upper end of the breathing tube penetratesout upwards and is fixed to the upper cover, a lower end of the breathing tube penetrates out downwards and is fixed to the lower cover, a guide plate, a bracket and a heating device which are sequentially fixed on an outer wall of the breathing tube from top to bottom are arranged in the silica gel bottle, the guide plate is of an inverted umbrella-shaped structure, the sensor and the heating device are in electric signal connection with a controller arranged outside the silica gel bottle, a connecting rod is arranged below the oil seal cup and is communicated with the breathing tube througha middle rod arranged in the middle of the oil seal cup, and a check valve is fixed at a tail end of the middle rod.

Description

technical field [0001] The invention relates to a transformer respirator and a method for regenerating silica gel in the respirator, belonging to the technical field of electric power equipment. Background technique [0002] Transformer respirator is an essential part of transformer equipment. Its main function is to filter and absorb moisture and impurities entering the air inside the transformer, so as to ensure the quality of transformer oil; the current structure of transformer respirator mainly includes shell, shell The body is equipped with a color-changing silica gel adsorbent, the top of the shell is provided with a connecting flange, and the bottom of the shell is provided with a gas filter device for filtering the gas entering the inner cavity of the shell from the outside. [0003] There are following problems in existing respirator: [0004] 1. When the silica gel used to store moisture reaches a certain amount, its water absorption effect gradually weakens unti...
