Description

Technical Field

[0001] This invention belongs to the field of transformer monitoring technology, specifically relating to an auxiliary mechanism for researching transformer vibration monitoring devices. Background Technology

[0002] With the rapid development of power grids, transformers, as fundamental equipment for power transmission and distribution, are becoming increasingly important. However, transformers often experience faults or even accidents during operation. A fault can range from affecting the operation of the power system and failing to meet electricity demand to threatening the safety of the power system. Traditional transformer fault detection methods are often reactive, requiring the faulty transformer to be repaired and the fault rectified before it can be put back into use, significantly impacting power supply efficiency.

[0003] However, during the statistical analysis of transformer faults, it was found that the transformer core and windings are components with a high failure rate. High-capacity power supply demands necessitate real-time monitoring of the transformer core and windings during operation to detect potential faults before they occur and eliminate them promptly. Since faults in the transformer windings and core typically cause vibrations in the transformer tank, vibration monitoring of the tank can detect latent faults. Therefore, installing vibration sensors in the transformer tank can provide timely information on the transformer's operating status. However, there are no pre-designated installation locations for vibration sensors in the transformer tank, making installation and removal complex, time-consuming, and labor-intensive.

[0004] This is a shortcoming of the existing technology. Therefore, it is very necessary to provide an auxiliary mechanism for a transformer vibration monitoring device to address the above-mentioned deficiencies in the existing technology. Summary of the Invention

[0005] In view of the shortcomings of existing traditional transformer fault detection methods, such as lag and the complex installation of vibration sensor detection methods, this invention provides an auxiliary mechanism for a transformer vibration monitoring device to solve the above-mentioned technical problems.

[0006] This invention provides an auxiliary mechanism for a transformer vibration monitoring device, comprising a transformer housing, a vibration monitoring device, and an auxiliary support.

[0007] The auxiliary support includes a vertical support frame, an upper support frame, and a lower support frame. The upper support frame, the vertical support frame, and the lower support frame are connected in sequence to form a concave receiving area.

[0008] The transformer housing is located within the concave receiving area of ​​the auxiliary support;

[0009] A first clamping adjustment component is provided at the upper support frame, and the first clamping adjustment component is in contact with the top surface of the transformer housing;

[0010] The vibration monitoring device is installed on the side of the vertical support frame facing the concave receiving area and is attached to the side of the transformer box;

[0011] A second clamping adjustment assembly is installed at the vertical support frame, which passes through the vertical support frame and connects to the vibration monitoring device. The first clamping adjustment assembly adjusts the auxiliary bracket to clamp the transformer tank vertically, while the second clamping adjustment assembly adjusts the vibration sensor to clamp the transformer tank, ensuring the accuracy of the vibration data of the transformer tank collected by the vibration sensor.

[0012] Furthermore, the first clamping adjustment assembly includes a first screw, a pressure plate, and a first handle;

[0013] The first screw passes through the upper support frame, and the upper support frame is provided with a first through threaded hole that matches the first screw;

[0014] The pressure plate is located at the lower part of the first screw, perpendicular to the first screw, and in contact with the top surface of the transformer housing;

[0015] The first handle is located on the upper part of the first screw and passes through the first screw. By rotating the first screw with the first handle, the pressure plate moves up and down, thereby realizing the installation and removal of the auxiliary support in the transformer tank.

[0016] Furthermore, the vibration monitoring device includes a vibration sensor, a sensor housing, a controller, and a control box;

[0017] The control box is located on the upper part of the sensor housing.

[0018] The vibration sensor is located at the bottom of the sensor housing, and the controller is located inside the control box.

[0019] The controller is connected to the vibration sensor;

[0020] The second clamping and adjusting assembly passes through the vertical support frame and is fixedly connected to the control box, ensuring that the bottom surface of the sensor housing fits snugly against the side of the transformer tank. This snug fit ensures effective vibration sensor acquisition. The controller preprocesses the vibration signals collected by the sensor to determine if the transformer vibration signals are abnormal, thus predicting potential transformer faults.

[0021] Furthermore, the second clamping adjustment assembly includes a second screw and a second handle;

[0022] The second screw passes through the vertical support frame and is fixed at the control box. The vertical support frame is provided with a second through threaded hole that matches the second screw.

[0023] The second handle is located on the side of the second screw away from the control box and extends through the second screw.

[0024] Furthermore, a magnetic clamping element is also provided inside the sensor housing;

[0025] The magnetic clamp secures the vibration sensor to the bottom of the sensor housing using screws. Rotating the second handle drives the horizontal movement of the second screw, allowing the vibration sensor to engage and disengage from the transformer housing. The magnetic clamp ensures a proper fit between the vibration sensor and the transformer housing. Compared to using only the magnetic clamp and vibration sensor, this auxiliary support structure prevents the vibration sensor from shifting or falling off due to transformer housing vibrations.

[0026] Furthermore, a battery is also installed inside the control box;

[0027] The battery is connected to both the controller and the vibration sensor. The battery powers both the controller and the vibration sensor, eliminating the need for an external power source. This avoids the need for wiring from the transformer housing and prevents interference from external power sources.

[0028] Furthermore, a communication module is also installed inside the control box;

[0029] The battery is connected to the communication module;

[0030] The controller connects wirelessly to the remote dispatch center via a communication module. This wireless connection eliminates the need for signal cables, simplifying installation.

[0031] Furthermore, the battery is also connected to a charge / discharge control module, which is connected to a solar panel.

[0032] Solar modules include solar panels and solar mounting systems;

[0033] The solar panel bracket is mounted on the upper part of the support frame, and the solar panels are angled and positioned on top of the bracket. The solar panels charge the batteries, ensuring that the batteries for the controller and vibration sensors are charged without frequent battery replacements.

[0034] Furthermore, the controller controls the vibration sensor to collect vibration signals at the transformer tank according to the preset sampling frequency, determines whether the vibration signal is abnormal, and reports a transformer fault warning to the remote dispatch center through the communication module when the vibration signal is abnormal.

[0035] Furthermore, the controller uses the HM4054E model with a sleep mode. This sleep mode controller saves power, switching between sleep and active modes. Upon reaching the sampling frequency, it enters active mode to collect vibration signals; in sleep mode, no signal is collected. This sleep mode controller saves power, eliminating the need for large solar panels and reducing costs.

[0036] The beneficial effects of this invention are as follows:

[0037] The auxiliary mechanism for a transformer vibration monitoring device provided by this invention enables rapid installation of the vibration sensor onto the transformer housing through an auxiliary bracket and a first and second clamping adjustment assembly. This is convenient, quick, and provides a good fit, ensuring accurate vibration signal acquisition and facilitating timely capture of transformer housing fault signals.

[0038] Furthermore, the design principle of this invention is reliable, the structure is simple, and it has a very wide range of application prospects.

[0039] Therefore, it is evident that the present invention has outstanding substantive features and significant progress compared with the prior art, and the beneficial effects of its implementation are also obvious. Attached Figure Description

[0065] Rotating the first screw 4.1 by the first handle 4.3 causes the pressure plate 4.2 to move up and down, thereby enabling the installation and removal of the auxiliary support 3 in the transformer housing 1;
