Description

Technical Field

[0001] This utility model relates to the field of power equipment maintenance technology, and in particular to a transformer tap changer adjustment device. Background Technology

[0002] Transformers are devices used to transform voltage in power systems. During their manufacturing or operation, in order to meet the needs of power grid operation, it is often necessary to adjust their voltage ratio. This adjustment is usually achieved by operating the on-load or off-load tap changer of the transformer itself.

[0003] For a large number of no-load tap-changing transformers, the tap changer adjustment currently relies mainly on manual on-site operation. The specific operation procedure is usually as follows: after the transformer is de-energized, maintenance personnel need to wear insulated protective equipment and reach the location of the tap changer on the transformer body by climbing or other means. Since the tap changer is usually installed on the upper part of the transformer tank, this means that the workers must perform work at height, which in itself brings the risk of falling from height.

[0004] After approaching the tap changer from a height, the operator needs to use manual tools to open the switch's protective cover, operate the internal locking or toggle mechanism, rotate the handle to switch to the target position, and finally restore the lock and close the cover. The entire process is not only cumbersome but also relies entirely on the operator's skill and sense of responsibility. In some confined spaces, poor lighting, or inclement weather conditions, the difficulty and risk of operation are further increased, making it easy to make mistakes or leave safety hazards due to improper operation. In summary, the existing manual adjustment method poses serious personal safety risks, while also being inefficient and difficult to guarantee the quality of operation.

[0005] Therefore, this utility model proposes a transformer tap changer adjustment device to address the shortcomings of the prior art. Utility Model Content

[0007] This utility model provides a transformer tap changer adjustment device, including: a base mechanism and a telescopic column vertically installed on the base mechanism; as well as a multi-axis positioning mechanism and a working module.

[0008] The multi-axis positioning mechanism is fixedly connected to the top of the telescopic column, and the working module is installed at the end of the multi-axis positioning mechanism.

[0009] The multi-axis positioning mechanism includes a primary slide rail, a secondary slide rail that can slide on the primary slide rail, and a drive module one for driving the secondary slide rail; a slider one that can slide on the secondary slide rail and a drive module two for driving the slider one; a tertiary slide rail fixed on the slider one; and a slider two that can slide on the tertiary slide rail and a drive module three for driving the slider two; the working module includes a lever module and a turning module mounted on the slider two.

[0010] Preferably, the base mechanism includes a base plate with wheels at the bottom and a hinged rotating arm that can be pulled outward, with a support leg threadedly connected to the rotating arm.

[0011] Preferably, the top of the support leg is provided with a throttle for rotating the support leg.

[0012] Preferably, the sliding direction of the primary slide rail is perpendicular to the sliding direction of the secondary slide rail.

[0013] Preferably, slider one slides along the top surface of the secondary slide rail; slider two slides along the outer wall of the tertiary slide rail.

[0014] Preferably, the transformer tap changer adjustment device also includes a vision module, which is installed on the slider two together with the working module.

[0015] Preferably, the working module further includes a gear adjustment module, which is rotatably mounted between the slider two, the lever module, and the turning module.

[0016] Preferably, the lever module and the rotary module are arranged side by side on the gear shifting module.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting a movable base mechanism and a liftable telescopic column, and integrating a multi-degree-of-freedom remote positioning operation system consisting of multi-stage slide rails, a drive module, a vision module and an operation module at the top of the telescopic column, solves the problem in the prior art that when manually adjusting the transformer tap changer, the operator must climb to a height and come into close contact with the high-voltage equipment, which poses a serious risk of falling from height and electric shock. It achieves the technical effect of allowing the operator to perform remote and safe operation from the ground, thereby completely avoiding personal safety risks and greatly improving the safety of transformer maintenance operations.

[0018] 2. This utility model, by employing a multi-axis positioning mechanism composed of multi-stage slide rails and drive modules, and cooperating with a vision module for precise guidance, and utilizing an operation module integrating a lever module and a turning module to perform standardized operations, solves the problems of inaccurate positioning, large operational errors, and unstable operation quality caused by manual operation in the prior art, which is easily affected by the operator's skills and the on-site environment. It achieves the technical effect of being able to adapt to complex environments and realize precise alignment and automatic adjustment of tap changers, effectively ensuring the accuracy and reliability of gear shifting operations, and improving the quality and efficiency of operations.

[0023] Please refer to Figure 3 and Figure 4 The working module is mounted on slider 10. The working module mainly includes a gear shifting module 14, a lever module 12, a rotary module 13, and a vision module 11. The gear shifting module 14 is rotatably mounted on slider 10, serving as a rotating platform for carrying and switching different actuators. The lever module 12 and the rotary module 13 are arranged side-by-side on the gear shifting module 14. When the gear shifting module 14 rotates, it can switch either the lever module 12 or the rotary module 13 to the working position directly below. The lever module 12 has a structure suitable for unscrewing the tap changer cover and moving the tap changer lever. The rotary module 13… It has a structure suitable for clamping and rotating the tap changer body. The vision module 11 is installed on the slider 10 together with the working module.

In another preferred embodiment, the integrated structure of the working module is as follows: the gear adjustment module 14 is rotatably mounted on the second slider 10, the lever module 12 and the turning module 13 are arranged side by side at the output end of the gear adjustment module 14, and the vision module 11 is also fixed on the second slider 10, with its lens facing the same direction as the working direction of the lever module 12 and the turning module 13.

[0025] Working principle: When the transformer needs to be adjusted, the telescopic column 1 is remotely controlled to a suitable height. Then, the drive module 1 4 is controlled to make the secondary slide rail 5 slide on the top surface of the primary slide rail 3. The drive module 2 6 is controlled to make the slider 1 7 slide on the top surface of the secondary slide rail 5. The drive module 3 9 can make the slider 2 10 slide on the outer wall of the tertiary slide rail 8, realizing multi-degree-of-freedom adjustment, which can meet the needs of various complex environments. The vision module 11 accurately moves the lever module 12 and the rotary module 13 to the top of the tap changer. The lever module 12 first unscrews the cover of the tap changer. The adjustment module 14 rotates to replace the actuator. The lever module 12 moves the tap changer plate to pull out the tap changer plate. Then, the rotary module 13 rotates the tap changer to achieve the purpose of adjustment. This allows people to remotely control the transformer from below and complete the adjustment operation. The wheels 202 on the front and rear sides of the telescopic column 1 facilitate the movement of the equipment. After the equipment is moved to the designated position, the rotating arms 203 around the telescopic column 1 are pulled out. The outer wall of the support leg 204 is threadedly connected to one end of the rotating arm 203. The handle 205 on the top of the support leg 204 is rotated to make the support leg 204 move downward. The contact foot at the bottom of the support leg 204 is in close contact with the ground, so as to achieve stable installation of the equipment.
