Description

Technical Field

[0001] The invention belongs to the technical field of transformer substation auxiliary equipment, and in particular relates to a transformer respirator maintenance auxiliary device in a transformer substation. Background Art

[0002] The respirator is one of the main components of the converter transformer. Due to the change of transformer oil temperature, part of the air will enter the transformer oil pillow capsule. The color-changing rubber in the respirator can absorb and dry the moisture in the air entering the oil pillow capsule to ensure the insulation strength of the transformer oil. During the long-term operation of the converter transformer, the color-changing rubber will absorb moisture and change color. When the rubber in the respirator changes color by more than 2 / 3, the rubber needs to be replaced to ensure the moisture absorption effect of the rubber. The respirator of the converter transformer is mostly a columnar body, the upper part of which is connected to the respirator connecting pipe, the middle part is provided with a glass cover for accommodating rubber, and the lower part is provided with an oil cup for accommodating transformer oil. The connection between the respirator and the respirator connecting pipe, and the connection between the respirator and the oil cup are all connected by metal plates and bolts. When disassembling or installing a large respirator, in order to prevent the respirator from falling to the ground or tipping over, at least three people are often required to cooperate with each other, two of whom lift the respirator and the other disassembles or installs the respirator; this method is not only time-consuming and labor-intensive, but also causes a waste of labor resources.

The rotating sleeve 13 and the adjusting screw 14 are screwed together, and the adjusting screw 14 is fixedly connected to the jacket 4. The cross arm 3 is clamped with the rotating sleeve 13 through an anti-slip head 15.

[0030] In order to achieve better results, a changing mechanism 16 is arranged between the upper clamp 1 and the adjusting seat 2. The changing mechanism 16 includes a transverse plate 17 and a rotating shaft 18. The transverse plate 17 is fixedly connected to the upper clamp 1.

Further, in order to facilitate the operation, the horizontal position of the adjustment seat 2 and the respirator carrier 8 can be adjusted by the change-direction mechanism 16. Specifically, under normal circumstances, in order to prevent the adjustment seat 2 from shifting, the pin 19 passes through the internal positioning hole 23 of the directional plate 22, and then the adjustment seat 2 is positioned. When the position of the adjustment seat 2 needs to be adjusted, the pull ring 20 is pulled up to disengage the pin 19 from the positioning hole 23.
