Description

Technical Field

[0001] This utility model belongs to the field of transformer noise monitoring technology, specifically relating to a noise monitoring device for dry-type transformers in rail transit. Background Technology

[0002] Dry-type transformers are key equipment in urban rail transit power supply systems, widely used in subways, light rail, and other applications. Dry-type transformers feature an oil-free design, eliminating pollution risks and offering advantages such as fire resistance, explosion-proof properties, and moisture resistance. They can operate normally in 100% humidity and are widely used in the traction power supply systems of urban subways and light rails, providing DC traction power to trains. In high-speed rail traction power supply systems, dry-type transformers are used to isolate the power grid from equipment, providing protection and filtering functions. During operation, dry-type transformers may experience aging, loosening, partial discharge, and other faults in their internal structure and insulation materials. These faults often lead to changes in noise levels. By monitoring noise, these anomalies can be detected promptly, allowing for proactive repair or replacement measures to prevent further escalation of the fault, thereby ensuring the safe and stable operation of the transformer and reducing economic losses caused by equipment damage.

[0003] Traditional dry-type transformer noise monitoring equipment can only monitor noise parameters at different locations by installing multiple sensors at different locations. This monitoring method is costly and the large amount of data is not conducive to unified collection and processing.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a noise monitoring device for dry-type transformers in rail transit.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a noise monitoring device for dry-type transformers in rail transit, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A noise monitoring device for dry-type transformers in rail transit includes:

[0009] The installation mechanism includes a transformer body, a first mounting frame, and a second mounting frame. The first mounting frame and the second mounting frame are respectively fixedly installed at the upper and lower ends of the transformer body. A crossbar is provided on both the first mounting frame and the second mounting frame, and a vertical plate is fixedly connected to the crossbar.

[0010] The monitoring mechanism includes a support plate mounted on a vertical plate, the support plate being slidably fitted with the vertical plate, a clamping plate mounted on the support plate, a noise sensor mounted on the clamping plate, a clamping groove formed on the clamping plate, a positioning screw hole formed on the lower surface of the clamping groove, a positioning screw screwed into the positioning screw hole, and the positioning screw engaging with the support plate.

[0011] Preferably, the noise sensor is equipped with a wireless signal transmission module, which is electrically connected to the noise sensor.

[0012] Preferably, the upright plate has a slot, and a plurality of toothed blocks are arranged inside the slot.

[0013] Preferably, a drive chamber is installed on the support plate, a drive motor is fixedly installed on one side of the drive chamber, and the output end of the drive motor is connected to a drive gear, which meshes with a gear block.

[0014] Preferably, two mounting rails are fixedly mounted on the lower surface of the first mounting bracket, and the cross-sectional shape of the mounting rails is U-shaped.

[0015] Preferably, a plurality of corner brackets are fixedly installed on one side of the mounting rail plate, and the corner brackets are provided with fixing holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) This utility model installs a vertical plate with a support plate on the transformer body, and the support plate can slide on the vertical plate. The support plate can be automatically slid by an electric drive device, thereby enabling the noise sensor to comprehensively monitor different positions of the transformer body. At the same time, the noise sensor is fixed on the support plate by a detachable clamping plate, which makes it convenient to repair and replace.

[0018] (2) This utility model sets up a drive chamber with a drive motor. By starting the drive motor, the active gear meshes with the tooth block, thereby driving the support plate to slide longitudinally on the vertical plate. The speed and starting frequency of the drive motor are set. When the support plate moves to the highest point, it will slide down under the influence of gravity. Due to the friction between the active gear and the tooth block, the support plate will not fall quickly. During the slow descent, the noise around the transformer body can be continuously monitored. After reaching the lowest point, the drive motor is restarted to make it rise again. This process can reduce the power consumption of the drive motor and continuously monitor the noise around the transformer body.

[0019] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0027] Please see Figures 1-4 As shown, a noise monitoring device for a dry-type transformer in rail transit includes:

[0028] The installation mechanism includes a transformer body 1, a first mounting frame 2 and a second mounting frame 3. The first mounting frame 2 and the second mounting frame 3 are respectively fixedly installed at the upper and lower ends of the transformer body 1. A crossbar 4 is provided on both the first mounting frame 2 and the second mounting frame 3, and a vertical plate 5 is fixedly connected to the crossbar 4.

[0029] The monitoring mechanism includes a support plate 10 mounted on the upright plate 5, which slides with the upright plate 5. A clamping plate 11 is mounted on the support plate 10, and a noise sensor 16 is mounted on the clamping plate 11. A clamping groove 15 is formed on the clamping plate 11, and a positioning screw hole is formed on the lower surface of the clamping groove 15. A positioning screw 18 is screwed into the positioning screw hole, and the positioning screw 18 is pressed with the support plate 10.

[0030] As can be seen from the above, this device installs a vertical plate 5 with a support plate 10 on the transformer body 1, and the support plate 10 can slide on the vertical plate 5. The support plate 10 can be automatically slid by an electric drive device, thereby enabling the noise sensor 16 to comprehensively monitor different positions of the transformer body 1. At the same time, the noise sensor 16 is fixed on the support plate 10 by a detachable clamping plate 11, which facilitates repair and replacement.

[0031] Example 2:

[0032] Please see Figures 1-4 As shown, a wireless signal transmission module 17 is installed on the noise sensor 16, and the wireless signal transmission module 17 is electrically connected to the noise sensor 16.

[0033] Specifically, the upright plate 5 has a slot 6, and several toothed blocks 7 are set inside the slot 6.

[0036] Specifically, several corner brackets 13 are fixedly installed on one side of the mounting plate 12, and the corner brackets 13 are provided with fixing holes 14.

[0037] As can be seen from the above, the present invention, by setting up a drive chamber 8 with a drive motor 9, drives the drive motor 9 to mesh with the drive gear and the tooth block 7, thereby driving the support plate 10 to slide longitudinally on the vertical plate 5. The speed and starting frequency of the drive motor 9 are set. When the support plate 10 moves to the highest point, it will slide down under the influence of gravity. Due to the friction between the drive gear and the tooth block 7, the support plate 10 will not fall quickly. During the slow descent, the noise around the transformer body 1 can be continuously monitored. After reaching the lowest point, the drive motor 9 is restarted to make it rise again. This process can reduce the power consumption of the drive motor 9 and continuously monitor the noise around the transformer body 1.
