Single-phase oil transformers OM with capacities 0.63, 1.25, 2.5, 4, 6, and 10 kVA are designed for consumers of single-phase electricity alternating current with a frequency of 50 Hz
Single-phase oil transformers OM are produced with nominal tension in primary winding 6 or 10 kV. Nominal tension in secondary winding is 0,23 kV. Scheme and connection group of windings 11-0.
Design features
Transformers designed to be mounted separately on electric poles and connected to the permanent installation of electrical boxes and can also be used for other single-phase devices as proposed in project.
Regulation of the transformer is carried out by the switch, which is installed on the active part of the HV side.
For the control of filling the tanks with oil transformers OM are equipped with oil level indicator located on the cover.
Oil transformers OM are supplied with mounted on HV side fuse puncture the breakdown voltage up to 1600 V.
