Description
Technical Field
The invention relates to the technical field of transformer substation operation and maintenance, in particular to the technical field of transformer respirator operation and maintenance, and more particularly relates to a transformer respirator replacing device.
Background
The transformer breather is used for adsorbing moisture in air entering the oil conservator rubber bag and the diaphragm, and removing and drying sundries and moisture in air entering the transformer oil conservator due to the change of the temperature of the transformer oil, so that the transformer is prevented from being affected with damp, and the stability of the insulation strength of the transformer oil is further ensured.
When the transformer is heated and expanded, transformer oil in the transformer expands along with the expansion, so that the volume of the transformer oil is increased, and redundant air in the transformer is discharged; when the transformer oil temperature decreases and contracts, air is sucked from the outside. When external air is sucked, the transformer oil in the oil storage box filters the external air, and then the silica gel absorbs moisture which is not filtered out, so that the transformer oil in the transformer is not invaded by moisture in the external air, and the moisture content of the transformer oil is always within the standard.
The transformer breather usually consists of an iron pipe and a glass container, wherein a desiccant (usually silica gel) is filled in the glass container, and an oil cup is arranged at the bottom of the glass container. Since the desiccant such as silica gel particles may lose their ability to adsorb moisture again due to too much moisture absorption caused by too long operation time, the desiccant particles in the transformer respirator need to be replaced, that is, the failed desiccant particles are taken out and replaced with desiccant particles with good adsorption performance.
In the prior art, the process of replacing the transformer breather is rather cumbersome and time consuming. First, two persons are usually required to assemble and disassemble the respirator, wherein one person uses a wrench to assemble and disassemble the bolt between the respirator and the pipeline, and meanwhile, the other person uses a hand to support the bottom of the respirator to prevent the bottom of the respirator from suddenly falling after the disassembly is completed. However, as is well known, the weight of a common respirator is 30 jin mostly, and the oil cup and the respirator body are glass pieces, so that a person holding the heavy respirator for a long time can easily and quickly fatigue both hands, and the respirator is easily dropped to the ground and then is broken due to negligence. Second, in the prior art, the time to install or remove the respirator is typically about 25 minutes per phase. If special conditions such as bolt corrosion occur, the disassembly becomes more difficult, and the time is longer. Furthermore, after the respirator is removed, the respirator needs to be manually lifted and turned upside down to discharge the desiccant of the silica gel particles which are wetted inside, and then the respirator is turned upside down again to load the brand-new silica gel particle desiccant into the respirator. Because the respirator is heavier, the operation is quite inconvenient, the physical strength of personnel is consumed, and the working strength is increased.

Preferably, the cross-sectional shape of the longitudinal connecting plate 32 is rectangular, and the longitudinal connecting plate 32 with the rectangular cross-sectional shape enables an operator to easily hold the longitudinal connecting plate 32 by hand, so that external force can be conveniently applied to turn the longitudinal connecting plate 32 up and down, and the convenience of operation is further improved.
Preferably, a reinforcing rib 322 is formed on the longitudinal connecting plate 32 at a position corresponding to the transverse shaft 34, so as to reinforce the structural strength of the entire longitudinal connecting plate 32 and prevent an operator from breaking the longitudinal connecting plate 32 at the position of the transverse shaft 34 when the longitudinal connecting plate 32 is turned over.
