Problems solved by technology

However, the current oil used is made of components with low expansion coefficient, so the volume change is not obvious, so the air volume of the air entering and exiting the oil conservator air bag is very small, and it is intermittent, similar to fish exhaling in water. "Gulp, gulp, gulp...", and the exhaust or inhalation time lasts for 1-2 hours; at the same time, the more critical thing is that the working load intensity of the transformer is based on the power consumption of the entire power grid. Therefore, it is unpredictable, so the expansion and contraction state of its cooling oil is also unpredictable, which also makes the "suction state" and "exhaust state" of its oil conservator air bag unpredictable

Abstract

The invention relates to the field of moisture absorber equipment, in particular to a moisture absorber connecting device and a moisture absorber with the same. The device comprises a connecting shell, a transparent cover body and a piston, wherein the upper end of the connecting shell is in sealed connection with an air nozzle of a transformer expansion tank air bag, the lower end of the connecting shell is in sealed connection with a main body of the moisture absorber, at least one observation window is further formed in the side wall surface of the connecting shell, and the observation windows are arranged along the periphery of the side wall surface of the connecting shell; wherein the transparent cover body is arranged in the connecting shell in a sleeved mode, the piston is movably arranged in the transparent cover body and can move up and down in the transparent cover body, and the piston is movably in sealed contact with the transparent cover body; the piston is provided with an air inlet through hole and an air outlet through hole, and the air inlet through hole and the air outlet through hole penetrate through the upper surface and the lower surface of the piston respectively. According to the moisture absorber connecting device, maintenance personnel can accurately know the working state of the air bag of the oil conservator.

Description

technical field [0001] The invention relates to the field of moisture absorber equipment, in particular to a connection device for a moisture absorber and a moisture absorber with the connection device. Background technique [0002] The moisture absorber is an important auxiliary equipment on the oil-immersed transformer. It can dry and filter the gas entering the transformer oil conservator air bag from the outside, so as to keep the inside of the oil conservator air bag dry and prevent the oil conservator air bag from breaking water and oil. Combination creates an explosion hazard. [0003] The principle of the original dehumidifier is similar to the dry bottle used in chemistry, and a replaceable dry core is used in the middle. Since the dry core is saturated with water, it will lose its function. Therefore, in order to avoid accidents, electric maintenance personnel must replace it regularly. Very troublesome. Then with the development of science and technology, a "mai...
