Description

Technical Field

[0001] The invention relates to the technical field of electric power equipment, and in particular to an automatic transformer fault alarm device and a use method thereof. Background Art

[0002] The transformer will generate a certain amount of noise during normal operation, and when a fault occurs inside it, the noise signal will change. For example, faults such as winding deformation, looseness or loose core will cause changes in the vibration characteristics of the transformer, thereby generating abnormal noise signals. Therefore, the existing technology can determine whether the transformer is abnormal by detecting the operating sound of the transformer. When the transformer is abnormal, it can automatically alarm, thereby facilitating the inspection and maintenance of the transformer and stable operation.

[0003] The existing automatic transformer fault alarm device is mainly installed on one or more sides of the transformer. Since the noise in various directions around the transformer will be different during operation, the accuracy of the identification alarm devices at different positions is also different. The device close to the fault position has better sensitivity and is easier to identify the fault sound signal. However, it is not convenient to perform multi-directional detection of the transformer in the prior art. Therefore, the automatic transformer fault alarm device has the problem of underreporting, or does not alarm when the transformer has a minor fault. When the fault expands and the noise increases again, the fault signal is not identified. This makes the device low in sensitivity, increases the fault degree of the transformer, and also increases the difficulty of transformer maintenance. In view of the shortcomings of the prior art, the present invention provides an automatic transformer fault alarm device and a method for using the same to solve the above problems. Summary of the invention

Through the design of a drive unit, the device performs all-round sound recognition and detection of the transformer main body, thereby improving the detection sensitivity and accuracy. At the same time, with the design of a noise reduction unit, the swivel is automatically lubricated when it moves along the annular guide frame, thereby preventing transmission position noise from affecting the fault sound detection effect.

[0017] A second aspect of the present invention provides a method for using a transformer fault automatic alarm device, the method comprising the following steps: step S1, a fault identification terminal records the operation sound of the transformer body through a microphone module at an initial position, and performs fault detection through sound recognition of the fault identification terminal. When there is no abnormal sound, it is determined that the transformer body is operating normally;

[0018] Step S2, regularly adjusting the position of the fault identification terminal to detect the fault sound at different positions of the transformer body. When adjusting the position of the fault identification terminal, the driving unit drives the rotating ring to rotate, and the rotating ring drives the limit seat and the fault identification terminal to adjust the target detection position;

[0019] Step S3, after completing the detection of all positions of the transformer body, if there is no abnormal fault sound, the transformer body is judged to be normal; if the detection sound is abnormal, the transformer body is judged to be abnormal, and an alarm is sounded through the alarm component to prompt personnel to repair.

[0020] The present invention discloses a transformer fault automatic alarm device and a use method thereof, which has the following beneficial effects:

[0021] 1. The transformer fault automatic alarm device provides support for the swivel through an annular guide frame, uses the swivel to provide installation limits for the limit seat and the fault identification terminal, and uses the design of the fault identification terminal and the microphone module to receive and process the working sound signal of the transformer main body. When the sound signal is abnormal, the alarm component is used to automatically alarm. Through the design of the driving unit, the swivel can rotate along the annular guide frame, thereby driving the limit seat and the fault identification terminal to adjust the position, and perform all-round sound recognition and detection on the transformer main body, avoiding the phenomenon of poor detection effect caused by the fault sound being in a blind spot, and improving the detection sensitivity and accuracy. At the same time, with the design of the noise reduction unit, the swivel is automatically lubricated when moving along the annular guide frame, avoiding the transmission position noise affecting the fault sound detection effect of the fault identification terminal and the microphone module on the transformer main body.

[0022] 2. The transformer fault automatic alarm device uses a limit groove to limit the swivel. The balls arranged on the swivel reduce the rotation resistance and improve the smoothness of the swivel rotation. In combination with the design of the noise reduction unit, lubrication is provided for the transmission position of the swivel and the annular guide frame. At the same time, a rotating wheel is used to lubricate the balls to reduce the ball resistance, thereby improving the system operation stability. When the swivel rotates on the annular guide frame, the swivel drives the balls to move. When the balls contact the rotating wheel, the rotating wheel is driven to rotate and the lubricating oil attached to the rotating wheel is transferred. The balls also attach the lubricating oil to the contact position between the annular guide frame and the swivel, thereby making the swivel rotate without abnormal noise, with low wear and long service life.

[0023] 3. The transformer fault automatic alarm device, through the design of the buffer mechanism, ensures that when the ball contacts and squeezes the rotating wheel, no hard collision occurs, providing contact position buffering, thereby further improving the stability of the system. When the ball contacts and thrusts the rotating wheel, the rotating wheel is subjected to force, and the rotating wheel drives the lubrication nozzle and the storage box to move horizontally. The storage box drives the slide to move and squeeze the first spring, thereby achieving buffered displacement, reducing impact, and improving the stability of the system.

[0024] 4. The transformer fault automatic alarm device, through the design of the wireless charging base and the wireless charging module, enables the fault identification terminal to be wirelessly charged every time it is in the initial position state, and charges the power supply inside the fault identification terminal, so that the fault identification terminal can be wirelessly installed. When the fault identification terminal fails later, it is convenient to overhaul and maintain. The locking component design makes it convenient to install and dock the fault identification terminal on the limit seat, and when the fault identification terminal needs to be overhauled and maintained later, it is also convenient to quickly unlock and remove the fault identification terminal from the limit seat, ensuring that the device is easy to maintain and replace.

[0038] The embodiment of the present application solves the existing automatic transformer fault alarm device by providing a transformer fault automatic alarm device and a method of using the same. The device is mainly installed on one or more sides of the transformer. Since the noise in various directions around the transformer will be different during operation, the accuracy of the identification alarm devices at different positions will also be different. The device close to the fault position has better sensitivity and is easier to identify the fault sound signal. However, it is not convenient to perform multi-directional detection of the transformer in the prior art. Therefore, the automatic transformer fault alarm device has the problem of underreporting, or does not alarm when the transformer has a minor fault. When the fault expands and the noise increases again, the fault signal is not identified.
