运行中到达的最高温度。

1、对干式变压器的线圈,当采用A级绝缘材料时,其极限工作温度在105℃时,最高温升应小于60℃。

2、当采用E级绝缘材料时,其极限工作温度在120℃时,最高温升应小于75℃;当采用B级绝缘材料时,其极限工作温度在130℃时,最高温升应小于80℃;当采用F级绝缘材料时,其极限工作温度在155℃时,最高温升应小于100℃。

3、当采用H级绝缘材料时,其极限工作温度在180℃时,最高温升应小于125℃;当采用C级绝缘材料时,其极限工作温度在220℃时,最高温升应小于150℃。

4、三绕组变压器三绕组变压器的每相有3个绕组,当1个绕组接到交流电源后,另外2个绕组就感应出不同的电势,这种变压器用于需要2种不同电压等级的负载。

5、额定容量是指容量最大的那个绕组的容量,一般容量的百分比按高中低压绕组有三种形式100/100/50、100/50/100、100/100/100。


The highest temperature reached in operation.
1, the coil of dry Transformer, when using Class A insulation material, its limit operating temperature is 105 °C, the maximum temperature rise should be less than 60 °C.
2, when using Class E insulation material, when the limit operating temperature is 120 °C, the maximum temperature rise should be less than 75 °C; When Class B insulation material is used, the maximum operating temperature of the class B insulation material should be less than 80 °C. When F insulation material is used, the maximum operating temperature of the class F is 155 °C, and the maximum temperature rise should be less than 100 °C.
3, when using H class insulation material, when the limit operating temperature is 180 °C, the maximum temperature rise should be less than 125 °C; When the C insulation material is used, the maximum operating temperature of the material is 220 °C, and the maximum temperature rise should be less than 150 °C.
The 4 and 3 winding Transformers have 3 windings for each phase of the three-winding Transformer. When 1 windings are connected to the AC power supply, the other 2 windings sense different potentials. This Transformer is used to require 2 kinds of different voltage levels. Load.
The rated capacity refers to the capacity of the winding with the largest capacity. The percentage of the general capacity has three forms of 100/100/50, 100/50/100, and 100/100/100 according to the high school low pressure winding.
