1 Scope

This standard applies to all shipboard power and lighting transformers, static converters, also suitable for marine starting transformers, static transformers, full And reactors and magnetic amplifiers, the rated capacity of less than 1kVA single-phase transformer rated capacity of less than 5kVA and three-phase transformer also pack Included within the scope of application. But except for special requirements.

2 General requirements

All devices in the range mentioned should not only comply with the relevant provisions of the following publications, but also in accordance with this standard and IEC No. 60092 Version was various other articles about additional requirements are listed.

3 winding arrangement

Transformer winding should be designed for dual (two separate windings). Starting Transformer type autotransformer may be used. Terminal 4 Suitable clearly marked terminals should be located in accessible places to facilitate external wiring. These terminals should be effectively secured, and appropriate Spaced or protection, to avoid being accidentally grounded, open circuit or touched.

5 cooling arrangement

5.1 transformer is preferably a dry air-cooled. Preferably 5.2 liquid-immersed transformers should be sealed. If the oil pillow type, should be designed to conform to IEC 60092-101.1994 regulations, ship Case appears inclined to run without the risk of spillage of liquid. If ventilation measures, it should be properly equipped with desiccant. 5.3 For liquid-immersed transformers should consider configuring a liquid over-temperature alarm and pneumatic protection device. NOTE. Installation Notes See IEC 60092-401. 1987 Chapter 15.

6 Voltage Regulation

For resistive load, the secondary voltage between the load and the fixed voltage drop of less than the rated capacity of the transformer should 5kVA per phase GB/T 22194-2008/IEC 60092-303.1997 ......
