Problems solved by technology

[0002] The transformer insulating bushing is an important part that leads the high and low voltage leads inside the transformer to the outside of the oil tank and connects to the power grid. During its long-term operation, it may be affected by changes in environmental conditions such as contamination, corrosion, flashover, heat generation, and mechanical force. The insulation performance declines rapidly and may lead to serious defects; if it is not discovered and corrected in time, the above-mentioned transformer insulation bushing problems may cause insulation breakdown and equipment damage, so real-time monitoring and treatment of transformer insulation bushings is required
Existing monitoring equipment for transformer insulating bushings is often directly fixed on the corresponding position of the transformer by bolts. However, for transformers in the field environment, conventional transformer insulating bushing monitoring equipment is very easy to affect its installation stability due to accidental shocks and other conditions. , thereby affecting its monitoring work

Embodiment 1

[0018] Such as figure 1 and figure 2 The transformer insulating bushing monitoring equipment shown includes a monitoring equipment casing 1, and the casing of the monitoring equipment is equipped with a bushing end screen adapter 2, an end screen grounding wire 3, a flow measurement module 4, and an online monitoring and merging unit 5. On-line monitoring of IED6, voltage transformer merging unit 7 and transmission optical cable 8; the bottom end and side ends of the monitoring equipment housing 1 are respectively provided with a bottom fixing device and a side fixing device; the bottom fixing device includes There is a support rod 9 extending in the vertical direction, which adopts an electric screw structure. Two fixed end plates 10 are arranged at the bottom of the support rod 9, and each fixed end plate 10 and the support rod 9 pass through The rotating shaft 11 is connected, and the rotating shaft 11 of each fixed end plate 10 is provided with a fixed motor 12 for drivi...

Embodiment 2

[0021] As an improvement of the present invention, such as image 3 As shown, the bottom end surface of the fixed end plate 10 is provided with a rubber anti-skid layer 19, which can improve the friction effect of the fixed end plate relative to the ground, and thus improve the overall support stability of the transformer insulating bushing monitoring equipment. further improvements.

[0022] The remaining features and advantages of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0024] As an improvement of the present invention, such as image 3 As shown, each fixed end plate 10 is provided with a fastening screw hole, and a fastening bolt 15 is arranged in the fastening screw hole, and a fastening end body 16 is arranged on the bottom surface of the fastening bolt 15. Made of rubber, the bottom end surface of the fastening end body 16 is provided with a plurality of downwardly extending conical bodies 17 . With the above-mentioned technical scheme, after the fixed end plate is placed well, it can form a downward pressure in the vertical direction through the fastening bolts, so that the fastening end body and the cone body at the end can be fixed relative to the soft ground surface. The degree of pressing and engaging treatment further improves the installation stability of the fixed end plate relative to the soft ground.

[0025] The remaining features and advantages of this embodiment are the same as those of Embodiment 2.
