Description

Technical Field

[0001] This utility model relates to the field of power transformer testing technology, and in particular to a comprehensive power transformer test bench. Background Technology

[0002] A power transformer is a static electrical device used to convert an alternating current (AC) voltage of a certain value into one or more different voltages at the same frequency. A power transformer is a static device with two or more windings that, in order to transmit electrical energy, converts the AC voltage and current of one system into the voltage and current of another system through electromagnetic induction at the same frequency. Typically, the values ​​of these currents and voltages are different. Before use, a power transformer needs to be tested to ensure its proper functioning; therefore, a comprehensive power transformer test bench is set up.

[0003] In existing technologies, such as the power transformer integrated test bench proposed in patent CN202322584800.X, a knob drives the upper pulley to rotate, which in turn drives the lower pulley to rotate via a belt. This causes the two winding shafts on the lower pulley to rotate around the center line of the lower pulley, thus winding up excess wire between the two winding shafts. This effectively reduces the risk of people tripping over excess wire and improves safety. A pawl limits the ratchet, ensuring that excess wire is wound up. Furthermore, a sliding shaft is provided between the knob and the drive shaft, allowing the knob to drive the ratchet to slide outward to release the pawl's limit.
