[0022] Embodiment 1

[0023] As Figure 1 shown:

[0024] A power transformer condition monitoring device includes a monitor 1.

[0025] In this implementation: The existing {public announcement number}: CN218633043U discloses a real-time monitoring device for the operating state of a power transformer; to solve the technical problems existing in this prior art, as disclosed in the background art above, "the flexibility of this device is relatively low, it is difficult to be applied to transformers of various sizes, and it is impossible to ensure its monitoring stability and reliability". In combination, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve the above problems, a slide carriage 2 and a slide block 3 are added on this basis.

[0026] Furthermore:

[0027] As Figure 1 - Figure 4 shown:

[0028] Combined with the above: It also includes a carriage 2, a slider 3, a connecting frame 4, a connecting rod 5, a threaded rod 6, a attaching plate 7, a stress plate 8 and a spring 9 provided on one side of the monitor 1. A carriage 2 slidably connected to the slider 3 is fixedly installed on one side of the monitor 1, and the slider 3 is fixedly installed on the surface of the connecting frame 4. The surface of the connecting frame 4 is also fixedly connected to the connecting rod 5. At the same time, a threaded rod 6 fixedly connected to the attaching plate 7 is threadedly connected to the inner surface of the connecting rod 5. A stress plate 8 is fixedly installed on the side of the connecting rod 5 away from the attaching plate 7, and the stress plate 8 is slidably connected to the surface of the monitor 1. One end of the spring 9 is fixedly connected to the surface of the stress plate 8.

[0029] In this embodiment: When the monitor 1 needs to be installed inside the transformer, the connecting frame 4 can be made to drive the slider 3 to slide along the carriage 2. At this time, the connecting frame 4 will drive the two stress plates 8 to move simultaneously and compress the spring 9, and the attaching plate 7 will also change its position. At this time, the monitor 1 can be placed inside the transformer, and then the connecting frame 4 is released. Under the rebound of the spring 9, the two attaching plates 7 will be connected to the inner surface of the transformer and the monitor 1 will be stably installed inside it. When the internal space of the transformer is too large, the attaching plate 7, the threaded rod 6 and the connecting rod 5 can be rotated relative to each other. At this time, the position of the attaching plate 7 will be further away from the monitor 1 under the rotation of the connecting rod 5 and the threaded rod 6, and it can be stably connected to the inner surface of the transformer. At the same time, under the rotation of the connecting rod 5 and the threaded rod 6, the elastic potential energy of the spring 9 can be increased, making the connection between the attaching plate 7 and the inner surface of the transformer more stable.

[0030] Furthermore:

[0031] In an alternative embodiment, the carriages 2 are symmetrically arranged on the surface of the monitor 1.

[0032] In this embodiment: The carriages 2 symmetrically arranged on the surface of the monitor 1 can provide a stable fulcrum for the slider 3 and the connecting frame 4. Thus, when the carriage 2 and the slider 3 slide, the connecting frame 4 can be driven to change the distance, providing favorable conditions for the installation of the monitor 1.

[0033] Furthermore:

[0034] In an alternative embodiment, an elliptical groove is provided at the connection between the slider 3 and the carriage 2.

[0035] In this embodiment: The elliptical groove provided on the surface of the carriage 2 enables flexible sliding between it and the slider 3 and the connecting frame 4, providing a favorable spatial basis for the position adjustment of the attaching plate 7.

[0036] Furthermore:

[0037] In an alternative embodiment, the connecting frames 4 are symmetrically arranged on both sides of the monitor 1.

[0038] In this embodiment: The connecting frames 4 symmetrically arranged on both sides of the monitor 1 can effectively slide with the carriage 2, thereby enabling the position of the attaching plate 7 to change, and effectively improving its overall flexibility.

[0039] Furthermore:

[0040] In an alternative embodiment, a threaded hole matching the threaded rod 6 is provided on the inner surface of the connecting rod 5.

[0041] In this embodiment: The threaded hole provided on the inner surface of the connecting rod 5 can drive the position of the attaching plate 7 to change when it rotates with the threaded rod 6, and thereby the device can be stably installed inside the transformer through the attaching plate 7.

[0042] Furthermore:

[0043] In an alternative embodiment, the force - receiving plates 8 are symmetrically arranged at both ends of the spring 9.

[0044] In this embodiment: The spring 9 symmetrically arranged at both ends of the force - receiving plate 8 can make the spring 9 have a stable fulcrum, and at the same time can also generate a stable thrust on the two force - receiving plates 8 when the spring 9 expands and contracts.

[0045] The working principle and usage process of the present utility model: When it is necessary to install the monitor 1 inside the transformer, the connecting frame 4 can be made to drive the slider 3 to slide along the carriage 2. At this time, the connecting frame 4 will drive the two force - receiving plates 8 to move simultaneously and compress the spring 9, and the attaching plate 7 will also change its position. At this time, the monitor 1 can be placed inside the transformer, and then the connecting frame 4 is released. Under the resilience of the spring 9, the two attaching plates 7 will be connected to the inner surface of the transformer and the monitor 1 will be stably installed inside it. When the internal space of the transformer is too large, the attaching plate 7, the threaded rod 6 and the connecting rod 5 can be rotated. At this time, the position of the attaching plate 7 will be further away from the position of the monitor 1 under the rotation of the connecting rod 5 and the threaded rod 6, and it can be stably connected to the inner surface of the transformer. At the same time, under the rotation of the connecting rod 5 and the threaded rod 6, the elastic potential energy of the spring 9 can also be increased, making the connection between the attaching plate 7 and the inner surface of the transformer more stable.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
