On-load tap changer for capacity and voltage regulation
On-load tap-changer for capacity and voltage regulation

This switch is suitable for three-phase oil-immersed on‑load tap changers and capacity‑adjustable distribution transformers with a rated voltage of 10 kV AC at 50 Hz or 60 Hz, and a maximum rating ranging from 160 (50) kVA to 630 (200) kVA (hereinafter referred to as “capacity‑and‑voltage‑adjustable transformers”). Under load, the switch can automatically perform capacity adjustment or voltage regulation in response to signals issued by its built-in controller, thereby enabling fine‑tuning of the transformer’s capacity and output voltage, improving power supply quality, and reducing losses.
The switch is applicable to three-phase oil-immersed on-load capacity and voltage regulation distribution transformer (hereinafter referred to as capacity and voltage regulation transformer) with AC 10kV, 50Hz or 60Hz and maximum rated capacity of 160 (50) KVA to 630 (200) kVA. Under the condition that the capacity and voltage regulation transformer is on-load, the automatic capacity regulate or voltage regulation switching can be carried out respectively according to the signals sent by the switch controller (with the switch itself), SO as to adjust the capacity and output voltage of the capacity and voltage regulation transformer, to improve the power quality and reduce the loss of the capacity and voltage regulation transformer.
