[0002] Transformers are a common type of electrical equipment used for voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. This includes dry-type transformers. When using transformers, it is necessary to install wireless fault monitoring devices to detect faults that occur during transformer operation in a timely manner and avoid damage.

[0003] When existing wireless fault monitoring devices are installed on dry-type transformers, because dry-type transformers do not have a shell for heat dissipation, it is necessary to first install fixing plates at the clamps before screws can be used to install the wireless monitoring device. The installation or disassembly process requires frequent use of tools, which makes the installation inconvenient.

[0004] Meanwhile, the clamps of dry-type transformers are mostly "I" shaped, with little usable space on the side, which further leads to inconvenience in installation. Therefore, a wireless monitoring device for transformer faults is proposed to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] ReferenceFigures 1-4 A wireless monitoring device for transformer faults includes a monitor housing 1 and a transformer clamp 2. The back of the monitor housing 1 is provided with a mounting groove 3. Further, the mounting groove 3 is provided with a first folding groove 7 for storing the connector 5 after folding and a fixing screw hole 8 for limiting the movable fixing plate 4 on the side facing the movable fixing plate 4, thereby realizing the connection between the movable fixing plate 4 and the monitor housing 1.

[0023] A movable fixing plate 4 is rotatably connected to the bottom end of the mounting groove 3. A connecting piece 5 for supporting the monitor housing 1 is provided between the movable fixing plate 4 and the mounting groove 3. Further, one end of the connecting piece 5 is rotatably connected to the top end inside the first folding groove 7, and the other end of the connecting piece 5 is rotatably connected to the top end of the second folding groove 9. When the connecting piece 5 is in the position... Figure 2 When fully unfolded, it can support the monitor housing 1, preventing the monitor housing 1 from tipping over due to vibrations during transformer operation.

[0024] Furthermore, multiple limiting rods 11 are fixedly connected to the bottom of the movable fixing plate 4 facing outward to prevent the clamping plate 6 from falling off;

[0025] It should be noted that the limiting rods 11 are in pairs, which can stably fix the clamping plate 6 and prevent the clamping plate 6 from shaking.

[0026] The bottom of the movable fixing plate 4 is provided with a clamping plate 6 for fixing the monitor housing 1 to the transformer clamp 2. During installation, the distance between the clamping plate 6 and the movable fixing plate can be adjusted by the fastening screw 13 to achieve the fastening effect.

[0027] Furthermore, the clamping plate 6 has a through hole corresponding to the limiting rod 11, the clamping plate 6 is slidably connected to the limiting rod 11, and a rotating seat 12 is fixedly installed on the clamping plate 6 corresponding to the threaded through hole 10, and a fastening screw 13 is rotatably installed on the rotating seat 12.

[0028] It should be noted that: a gap is formed between the clamping plates 6, allowing the movable fixing plate 4 to... Figure 1 The state shown is fixed on the surface of the "I" shaped clamp;

[0029] A further advantage of the above is that, during installation, the distance between the clamping plate 6 and the movable fixing plate 4 can be adjusted by the fastening screw 13 to achieve a fastening effect. After folding, the fastening screw 13 is located in the fixing screw hole 8. At this time, the movable fixing plate 4 and the clamping plate 6 are fixed to the mounting groove 3 by rotating the fastening screw 13 to achieve a limiting effect.

[0030] In use, the fastening screw 13 is rotated counterclockwise by hand until it leaves the fixing screw hole 8, releasing the fixation between the movable fixing plate 4 and the mounting groove 3. The movable fixing plate 4 is then rotated along the bottom of the mounting groove 3, causing the connecting piece 5 to unfold. After the movable fixing plate 4 has rotated 90°, the connecting piece 5 is fully unfolded. Figure 2 As shown, the monitor housing 1 and the movable fixing plate 4 form a stable triangular structure to fix the monitor housing 1 and prevent it from tipping over due to vibrations during transformer operation. The open ends of the movable fixing plate 4 and the clamping plate 6 are inserted into the transformer clamp 2, forming a... Figure 1 As shown, finally rotate the fastening screw 13 clockwise to drive the clamping plate 6 to slide along the limiting rod 11 and squeeze the transformer clamp 2. After adjusting to the appropriate tightness, connect the monitor housing 1 to the probe in the prior art to complete the installation.

[0031] Similarly, after the fastening screw 13 is turned in the opposite direction to release the fixation, the movable fixing plate 4 is rotated in the opposite direction along the bottom of the mounting groove 3, which drives the connecting piece 5 to fold into the first folding groove 7 and the second folding groove 9. At this time, the fastening screw 13 is located in the fixing screw hole 8. Finally, the movable fixing plate 4 and the clamping plate 6 are fixed to the mounting groove 3 by rotating the fastening screw 13 clockwise. Installation and disassembly can be completed without the use of tools, realizing the function of easy use.
