Description

Technical Field

[0001] This utility model relates to the field of fault detection technology, and in particular to a fault detection device for power transformers. Background Technology

[0002] A power transformer is an electrical device used to change the magnitude of AC voltage. It mainly consists of an iron core and windings. Its function is to increase or decrease voltage in a power system. Increasing voltage facilitates long-distance power transmission and reduces line losses; decreasing voltage provides power for users. Power transformers can be divided into step-up transformers and step-down transformers according to their uses. They are characterized by high efficiency and reliability and can work stably under different load conditions. In a power system, the power transformer plays a crucial pivotal role in ensuring the safe and stable transmission and distribution of electrical energy.

[0003] Existing technologies, such as the utility model patent with publication number CN220064346U, disclose a power transformer fault detection device. This device aims to solve the problem that current traditional power transformer fault detection devices simply lift the entire power transformer to inspect its bottom. However, this lifting increases the transformer's height, making it difficult for shorter personnel to easily inspect the bottom. The device includes a base shell and a strip-shaped shell connected to the top side of the base shell with screws. An adjustable detection mechanism is movably inserted through one side of the strip-shaped shell. This utility model clamps the power transformer from the middle, and after clamping, a first motor directly flips the transformer, allowing for direct flipping and inspection of both the top and bottom without lifting the transformer.

[0004] Currently, most transformer fault detection equipment clamps and rotates the transformer during inspection to achieve all-round observation and inspection. However, transformers are irregularly shaped and heavy. In actual use, the motor and telescopic rod are directly subjected to force, and the transformer's weight can easily cause deformation and damage, which is not conducive to the normal use of the equipment. This needs to be improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing transformer fault detection equipment, which clamps and rotates the transformer during inspection to achieve all-round observation and inspection. However, transformers are irregularly shaped and heavy, and the equipment is prone to deformation and damage due to the direct force on the motor and telescopic rod and the weight of the transformer during actual use, which is not conducive to the normal use of the equipment. Therefore, this invention proposes a power transformer fault detection device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a power transformer fault detection device, comprising a support leg and a panel. The support leg is fixedly connected to the lower surface of the panel. The upper surface of the panel has a mounting hole and a through hole. An observation device is provided on the surface of the panel. The observation device includes a protective cover, which is fixedly connected to the lower surface of the panel. A first mirror is fixedly connected to the inner wall of the protective cover, and a guide frame is fixedly connected to the inner wall of the protective cover. A control block is slidably connected to the guide frame. A second mirror is fixedly connected to one side of the control block. The through hole is located above the second mirror. The control device is provided on the surface of the support leg. This solution effectively installs the power transformer, reducing the possibility of transformer shaking and loosening during the detection process. Furthermore, this solution uses only light refraction to observe the bottom of the transformer, improving detection efficiency without posing safety hazards and facilitating normal use of the equipment.

[0007] Preferably, there are two guide frames and two control blocks, and the two guide frames and control blocks are set in a mirror image to ensure stable displacement of the second mirror.

[0008] Preferably, an observation plate is fixedly connected to the surface of the guide frame. The observation plate is located above the first mirror, and one side of the observation plate is fixedly connected to the surface of the panel to facilitate normal use of the equipment.

[0009] Preferably, the first mirror and the second mirror are arranged opposite each other, and both the first mirror and the second mirror are tilted at 45°.

[0010] Preferably, the control device includes a positioning sleeve, which is fixedly connected to the surface of the support leg. A pull rope is inserted through the positioning sleeve, and one side of the pull rope is fixedly connected to the surface of the control block. Before use, the power transformer is placed on the panel, and then the power transformer is installed by bolts and mounting holes. When observing the bottom of the power transformer, it is only necessary to rotate the rotating block. The rotating block drives the transmission disc to rotate, and then the pull rope pulls the control block to move the second mirror. The maintenance personnel can observe the image of the second mirror in the first mirror through the observation plate. When adjusting the position of the second mirror, the bottom of the power transformer can be observed stably.

[0011] Preferably, a mounting block is fixedly connected to the surface of the support leg, and a transmission disc is rotatably connected to the upper surface of the mounting block. One end of the pull rope is inserted into a groove on the transmission disc, and rotating the transmission disc can drive the control block and the second mirror to move by pulling the rope.

[0012] Preferably, a rotating block is fixedly connected to the upper surface of the transmission disk, and the edge of the rotating block is provided with an anti-slip groove, so that rotating the rotating block can effectively drive the transmission disk to rotate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, before use, the power transformer is placed on the panel, and then installed by bolts and mounting holes. When observing the bottom of the power transformer, simply rotate the rotating block, which drives the transmission disc to rotate. Then, pull the rope to move the control block and move the second mirror. The maintenance personnel can observe the image of the second mirror in the first mirror through the observation plate. When adjusting the position of the second mirror, the bottom of the power transformer can be observed stably. This solution effectively installs the power transformer, reducing the possibility of the transformer shaking or loosening during the inspection process. At the same time, this solution only uses light refraction to observe the bottom of the transformer, improving inspection efficiency without any safety hazards, and facilitating the normal use of the equipment.

[0017] In this embodiment, there are two guide frames 56 and two control blocks 55. The two guide frames 56 and control blocks 55 are set in a mirror image to ensure the stable displacement of the second mirror 54.

[0018] Specifically, an observation plate 52 is fixedly connected to the surface of the guide frame 56. The observation plate 52 is located above the first mirror 53.

A pull rope 62 is inserted through the positioning sleeve 65, and one side of the pull rope 62 is fixedly connected to the surface of the control block 55. Before use, the power transformer is placed on the panel 2, and then the power transformer is installed by bolts and mounting holes 3.

When observing the bottom of the power transformer, simply rotate the rotating block 61.

When adjusting the position of the second mirror 54, the bottom of the power transformer can be observed stably. This solution effectively installs the power transformer and reduces the possibility of the transformer shaking or loosening during the inspection process. At the same time, this solution only uses light refraction to observe the bottom of the transformer, which improves the inspection efficiency and eliminates safety hazards, facilitating the normal use of the equipment.
