Embodiment Construction

[0018] Such as figure 1 with figure 2 As shown, the replacement device for the embedded groove of the transformer thermometer includes a main body cover 1 with openings at both ends in the axial direction. For easy observation, the main body cover 1 can be made of a transparent material with suitable strength, which is convenient for observing the liquid level of the oil and the outer cylinder. s position. The lower end of the main body cover 1 is provided with a compression plate 2 perpendicular to the axis of the main body cover 1, and the upper surface of the compression plate 2 is provided with a fixed magnet that can be magnetically attracted to the transformer 25 to compress the compression plate 2 on the transformer. 3. In this embodiment, the compression plate 2 is in the shape of a step with a large bottom and a small top. The shape of the fixed magnet 3 is adapted to the shape of the compression plate 2. The compression plate 2 and the fixed magnet 3 of this struct...

Abstract

The invention discloses a transformer thermometer embedded groove replacing device. The device comprises a body cover, wherein a lower end of the body cover is provided with a compaction plate and a fixed magnet capable of compacting the compaction plate on a transformer, the body cover is provided with a cut valve and is internally provided with an outer cylinder, the outer cylinder is internallyrotatably equipped with an inner cylinder, a lower end of the inner cylinder is equipped with an inner clamping block, the outer cylinder is fixedly equipped with a driving wedge capable of driving the inner clamping block to clamp an embedded groove inwards when the inner cylinder rotates, the inner cylinder and the outer cylinder are provided with a locking mechanism capable of realizing relative locking of the two, an inner centering device of the inner cylinder is further comprised, and a lower end of the centering device is equipped with a grasping mechanism capable of grasping a thermometer. The device is advantaged in that oil release, oil stop and standing operation for the transformer are not needed, the work time is greatly reduced, work efficiency is greatly improved, and the main transformer power failure time is saved.

Description

technical field [0001] The invention relates to a device for replacing an embedded groove of a transformer thermometer. Background technique [0002] Large-scale power transformers have body / winding thermometers, and the thermometers are placed in the embedded groove of the transformer. Due to the aging of the rubber pad or the corrosion of the embedded groove, oil leakage defects will occur at the embedded groove. At present, the defect treatment method is: Drain the transformer oil below the embedded groove, replace the rubber pad of the embedded groove or directly replace the embedded groove, then refill the oil, let it stand, and complete the defect treatment. This kind of processing method needs at least 3 days, and the working hours are long and the efficiency is low. There is an urgent need for a device that can quickly replace the rubber pad of the embedded groove or directly replace the embedded groove. Contents of the invention [0003] The technical problem to...
