SZ11 series 10KV, 35KV three-phase transformer load tap

 

1.IntroductionWith OLTC transformer tap as OLTC transformer. OLTC transformer leads from a number of transformer windings by on-load tap tap tap, the promise not to cut off the load current circumstances, change the tap position to change the effective number of turns, the transformer that changes the Pressure ratio to achieve the purpose of the output voltage constant. Tap in the transformation process of the energy normally used to absorb excessive resistance limiting, loop current.

2.OLTC transformer is mainly used forA, stable power grid voltage at the load center to improve the quality of power supply;B, the contact between the two networks as a liaison between the transformers, load tap used to distribute the load between the networks;C, used to adjust the load current and power with the power to improve workplace productivity;D, the voltage must be strictly controlled for the occasion, such as electronics, medicine and other fields for power transformers.

3.Normal conditions of useNot more than 1000m above sea level outdoor or outdoorMaximum ambient temperature is the highest daily average temperature of +40 °C +30 °CThe highest annual average temperature of the minimum temperature -25 °C +20 °CAvailable upon request to run in the special conditions of use transformer

4.Implementation of standards1)GB1094.1-2-1996, GB1094.3-5-2003 power transformer;2)GB/T6451-1999 three-phase oil-immersed power transformers and technical requirements.
