Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of desiccant, in particular to an explosion-proof desiccant. Background Art
[0002] The desiccant is mainly used to provide a channel for the gas inside the transformer to enter and exit when the temperature changes, and to relieve the pressure on the oil tank caused by temperature changes during normal operation. When the oil expands and contracts during the operation of the transformer, it plays the role of suction and exhaust. The desiccant contains a desiccant (silica gel) that can absorb moisture and water. When the silica gel causes the desiccant to absorb moisture or become saturated with water, it will deteriorate and lose its moisture absorption capacity, so it must be checked and replaced regularly.
[0003] However, in actual use, due to the complex working state of the transformer, whether the color-changing silica gel in the desiccant needs to be replaced cannot be intuitively concluded simply by observing the color-changing silica gel. It requires a high level of experience and judgment from the inspectors, and the service life and working state of the color-changing silica gel need to be estimated during regular inspections. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an explosion-proof desiccant in view of the above-mentioned technical deficiencies. The connecting column arranged between the convex edges on both sides cooperates with the contrast piece to realize the color change of the contrast piece; the usage and the deadline for replacement can be quickly judged, and the relevant planning work can be done well. At the same time, through the abnormal state of the contrast piece on the other side, it can be judged whether the water-absorbing silica gel is in an abnormal state, so as to further understand whether it needs to be replaced.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: comprising a main body; convex edges protruding radially outward from the outside of the main body are arranged on both sides of the length direction of the main body; a detachable connecting column is connected between the two convex edges; the position between the two convex edges on the main body is filled with color-changing silica gel; a contrast piece is inserted on the connecting column; the contrast piece; multiple contrast pieces are filled with color-changing silica gel samples in different working states; an observation window for observing the color of the color of the color-changing silica gel in the main body is arranged on one side of the contrast piece on the main body.
[0006] To further optimize the technical solution, the connecting columns are respectively arranged around the convex edge; the two ends of the connecting column are fixed to the convex edge through nuts and threads on the outer side of the connecting column.
[0007] To further optimize the technical solution, a through hole for passing a connecting column is provided in the middle of the contrast piece; and a gasket is provided between two adjacent contrast pieces installed on the connecting column.
[0008] To further optimize the technical solution, the outer side of the contrast member is set to a circular arc surface corresponding to the convex edge.
[0009] To further optimize the technical solution, the color-changing silica gel samples in the comparison piece on the connecting column on one side are arranged in sequence according to different water absorption degrees, and different color-changing silica gel samples in abnormal states are arranged in the comparison piece on the connecting column on the other side.
[0010] Compared with the prior art, the utility model has the following advantages: the connecting column arranged between the convex edges on both sides cooperates with the contrast piece, and this structure advantageously ensures the color change through the contrast piece; quickly judges the usage and the deadline for replacement, and does a good job in planning related work. At the same time, through the abnormal state of the contrast piece on the other side, it is judged whether the water-absorbing silica gel is in an abnormal state, which is convenient for further understanding whether it needs to be replaced.
