1. Product Introduction
Dry type transformers have been widely used due to their high dielectric strength, superior environment performance and low operating noise. The operational reliability of dry type transformers is highly dependent on its insulation performance, which is closely related to the heat generation and dissipation inside dry-type transformers. Overheating of the transformer winding will not only cause the insulation to accelerate aging, but also cause insulation breakdown, which may cause fire, explosion and other serious accidents.
HQ-35 series dry type transformers fiber optic temperature monitoring system can position the temperature sensors to transformation windings and coil. It can monitor the real temperature of winding coil and magnetic core in real time and reduce the error caused by indirect temperature measurement.
