Self-healing type moisture absorber for transformer

Abstract

The invention discloses a self-healing type moisture absorber for a transformer. The self-healing type moisture absorber comprises a glass cylinder; a filter net cylinder is arranged in the glass cylinder; a certain gap exists between the filter net cylinder and the inner wall of the glass cylinder; a filter net cylinder main shaft connecting upper and lower flanges of the glass cylinder is arranged in the center of the filter net cylinder; annularly arranged carbon fiber heating nets are fixedly arranged on the filter net cylinder main shaft; a temperature sensor is arranged in the carbon fiber heating nets; when the moisture absorber is in use, the filter net cylinder is filled with moisture absorbent; a weighing sensor is fixed at the bottom of the glass cylinder; heating cores are arranged in a water outlet cavity and an air inlet cavity; a controller, connected with the upper flange, is arranged in the outer side of the glass cylinder; a controller unit adopting an industrial-level embedded microprocessor is arranged in the controller; and the carbon fiber heating nets, the temperature sensor, the weighing sensor and the heating cores are connected with the controller separately through wires. The self-healing type moisture absorber has the characteristics of simple structure, economical benefit, practicability, and wide application range, and the self-healing type moisture absorbing characteristic of the moisture absorber for the transformer is realized.

Description

technical field [0001] The invention relates to auxiliary appliances for transformer equipment, in particular to a transformer self-healing moisture absorber. Background technique [0002] Transformer dehumidifier is a glass container filled with hygroscopic materials such as color-changing silica gel, which can filter impurities and moisture in the air to keep the cleanliness and insulation strength of transformer oil and prevent the aging of transformer insulating oil. [0003] In the traditional sense, the dehumidifier uses disposable color-changing silica gel to absorb the moisture of the gas entering and leaving the transformer oil conservator. When the water absorption of the silica gel is saturated, the silica gel needs to be replaced manually to maintain the hygroscopic function of the dehumidifier. When replacing the silica gel, it is necessary to remove the moisture absorber from the transformer, pour out the old silica gel, and put in new silica gel. Frequent rep...

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-healing moisture absorber for transformers, which solves the problem that existing moisture absorbers need to frequently replace the moisture absorber, uses the method of heating the damp moisture absorber to remove moisture, and has a simple structure. The operation saves time and effort, which can improve the reliability of transformer operation. It can economically, effectively and safely perform moisture absorption and dehumidification for transformers of different capacity levels, and has the characteristics of wide application range.
