宣城干式变压器：每匝电压和磁通密度

每匝电压和磁通密度 　　
在一定的供电频率下，每匝电压和铁心总磁通之间保持恒定。因为对于一定的铁心来说，铁心柱的横截面积是常数，这意味着在一定的供电频率下，每匝电压和磁通密度的关系也保持不变。在一个特定的绕组中，匝数也将保持不变（带有分接头的绕组除外，对此后面将简述）。宣城干式变压器所在系统的额定电压和频率以及接入系统的绕组的匝数决定了比以前运行的额定磁通密度。
宣城干式变压器设计人员总是希望在不产生磁饱和的前提下，铁心中的磁通密度尽可能高。系统频率一般被控制在极小的范围内，这样，如果宣城干式变压器所在系统的电压也在额定电压的极小范围内波动，那么设计人员就会使额定磁通密度比预期电压在大范围内变化的情况更加接近饱和。
在英国，通常情况下允许系统电压高于额定值10%。例如，在负载不足的情况下，这些系统的宣城干式变压器磁通密度必须保证在这种运行条件下的安全系数低于磁饱和限值。

Voltage per turn and the magnetic flux density

Power at a certain frequency, the voltage per turn and the core is maintained between the total magnetic flux constant. Because for a given core, the core columns of the cross-sectional area is constant, which means that at the power supply frequency, the voltage per turn and the relationship between the magnetic flux density is kept constant. In a specific winding, the turns will remain unchanged (with the exception of the tap winding, which are briefly described later). Transformer where the rated voltage and frequency as well as access to the system determines the number of turns than the previous run of the rated flux density.
Transformer designers do not always want to produce magnetic saturation of the premise, iron core flux 华盈非晶合金变压器有限公司density as high as possible. System frequency is generally controlled in a very small range, so that if the voltage of the system where the transformer rated voltage is also very small range of fluctuation, then the designer will make the rated flux density than the desired voltage variation in a wide range the situation is more close to saturation.
In the UK, usually allows the system voltage higher than the rated 10%. For example, in the case of insufficient load, the transformer flux density of these systems must ensure that the operating conditions in such a safety factor than the magnetic saturation limits.
