QZB Marine Auto-transformer

This reduced-voltage auto-transformer (hereinafter referred to as auto-transformer) series is used for voltage reduction starting of squirrel-cage motor with three phase current AC 50~60Hz.in addition as the power 11-11-315KW auto-transformer must be isolated completely from the system when the starting is finished.

Service conditions:

A height above sea-level not exceeding 1000m;
A temperature of ambient air not below -25℃ and above +45℃；
Relative air humidity: ordinary type ≤85℃, damp and hot type ≤95℃;
In medium without risk of explosion and with too insufficient air and electric insulation dust to corrode metal and damage insulation;
In environment without water vapor and equipped with rainproof device.

Structure:

The auto-transformer is type of three phase star connection and air cooled.
Transformer is of 60%, 80% rated voltage ratio tapping, and the obvious voltage percentage sign is existed at the tapping.
