SYTXYL8 Series On-load capacity-adjusting and voltage-regulating tap-changer

Overview

The core component of the on-load capacity-adjusting voltage-regulating transformer is suitable for rural power grids with large seasonal load changes and some urban commercial areas, development zones, industrial areas and other power distribution areas with significant day and night load changes. When the load of the power grid is light or close to no load, the project product will intelligently change the transformer from large capacity to small capacity operation, greatly reducing the line loss of the power grid and saving electric energy. The product includes a voltage regulating function, and the number of tap positions is 3/5.

 At the same time, the project product can automatically adjust the voltage according to the fluctuation of the grid voltage, thus stabilizing the grid voltage and improving power quality. Function: The horizontal structure is used to arrange the contacts on both sides of the switch to save the installation space of the transformer and reduce the manufacturing cost of the transformer. The product adopts multi-break arc extinguishing technology. Under the same stroke, the arc of multiple breaks is longer than that of a single break. , which is beneficial to the recovery of the arc gap dielectric strength. In addition, since the power supply voltage is applied to several fractures, the voltage applied to each fracture is reduced, that is, the recovery voltage of the arc gap is reduced, which also helps to extinguish the arc.
