Main components
This product is made of high-strength enamelled wire and high-quality silicon steel sheet. BK series transformer core is shell type, which is laminated by silicon steel sheets; BKC series iron core is C-core type.
Technical characteristics
1. BK, BKC and other series of control transformers (hereinafter referred to as transformers) are applicable to power supply for local lighting in industrial and mining enterprises, power supply for control circuits in electrical equipment, and power supply for signal lights and indicator lights in circuits with AC 50Hz~60Hz and voltage up to 500V.
2. The transformer can work for a long time under rated load.
3. The primary and secondary windings of the transformer are separated. When the secondary has only one winding, it bears all the rated capacity of the transformer. If the secondary has both control, lighting and indicator windings, it is wound separately according to the distribution of winding capacity. For the transformer with single winding and intermediate tap, the capacity of each intermediate tap is less than the rated capacity of the transformer, and only the maximum voltage output terminal can bear the rated capacity.
4. The product meets the standard: GB19212.3-2006.
5. Product insulation grade: Class B III.
Environmental conditions editing broadcast
1. The ambient air humidity is - 5 ℃ to+40 ℃, and the 24-hour average value shall not exceed+35 ℃;
2. The altitude of the installation site shall not exceed 2000 meters;
3. The relative humidity of the atmosphere shall not exceed 50% when the ambient air humidity is+40 ℃. There can be a higher relative humidity at a lower temperature. The average maximum humidity of the wettest month is 90%, and the average minimum temperature of the month is+25 ℃. In addition, the condensation on the product surface due to temperature changes shall be considered.
4. Places without violent vibration and impact vibration;
5. A place protected from rain and snow;
6. The voltage waveform is approximately sine wave.
