Description

Technical Field

[0001] The utility model relates to the technical field of power products, in particular to a on-load tap-changer with a buffering function. Background Technique

[0002] In the power system, as an important accessory of the transformer, the on-load tap-changer undertakes the important task of adjusting the output voltage without interrupting the load current.

[0003] With the continuous expansion of the power grid scale and the increasing power load, the operation stability and reliability of the on-load tap-changer have become the key factors to ensure the continuity and quality of power supply. However, in actual applications, the on-load tap-changer is often subjected to large mechanical impacts and vibrations during frequent opening and closing processes. These external forces will not only cause wear to the mechanical structure of the switch, but may also affect its internal electrical components through conduction, thus triggering faults or reducing the service life.

[0026] In this embodiment: Since the buffering mechanism 2 is installed on the switch body 1, the switch body 1 can be protected through the buffering mechanism 2, so that the switch body 1 can be prevented from being impacted during operation and affecting the operation. By controlling the adjusting mechanism 3, the height and installation angle of the switch body 1 can be adjusted, thereby making the practicality of the device higher.

Through the elastic force of the buffer spring 202, a buffering effect can be achieved, so that the switch body 1 can be buffered when impacted.

[0029] Specifically, as Figure 4As shown in the figure, the adjusting mechanism 3 includes a threaded block 308 mounted on the balance rod 302. The threaded block 308 is in threaded connection with the threaded rod 303, and a knob 309 is fixedly connected to the threaded rod 303.
