兰州干式变压器的发热及散热过程   
兰州干式变压器带上负载后,在它的铁芯、线圈中就产生损耗。这些损耗转化为热,发出热量,温度逐渐升高,线圈或铁芯与周围媒质间就产生了温度差。热量就从线圈,铁芯发散到煤质中去。这样,一部分热量使兰州干式变压器温度升高,另一部分热量发散到煤质。温度逐渐升高时,单位时间内积累的热量逐渐减少,而散发的热量逐渐增加。终温度不再升高,热量全部消散到周围煤质中去。
兰州干式变压器一般是长期连续运行的。在设计这种兰州干式变压器时,是计算其额定负载下的稳定温升。
在稳定散热情地 址:山东聊城经济开发区华山路南首30号况下,线圈及铁芯中所有产生的热量都发散到煤质中去。热量所走的路径是很复杂的,对于油浸式兰州干式变压器,可分为下列几部分:
1. 从线圈或铁芯的中部流到其外表面,这是依靠传导的作用;
2. 从线圈或铁芯的外表面到油中,再到油箱壁,这是依靠对流的作用。
3. 从油箱壁到空气,这是依靠对流及辐射的作用。

Transformer heating and cooling process

Transformer belt the load in its core, coil, generating losses. These losses are converted to heat, and emits heat, the temperature was gradually increased, the coil or between the core and the surrounding medium, to produce a temperature difference. Heat from the coil, core the divergence to coal. Thus, part of the heat so that the transformer temperature increases, another part of the heat is dissipated to the coal quality. The temperature was gradually increased, the accumulation of heat within the unit time is gradually reduced, while gradually increasing the heat. Final temperature no longer rises, all the heat dissipated into the surrounding coal.
Power transformers are generally long-term continuous operation. In the design of this transformer, the calculation of the stability of the temperature rise under its rated load.
Stability under thermal conditions, all the heat generated in the coil and the iron core are diverging to QUALITY go. The calories walking path is very complex, for oil-immersed power transformers, can be divided into the following sections:
1 from the middle of the coil or core flow to the outer surface thereof, it is to rely on conduction of;
2 to the oil from the outer surface of the coil or core, and then to the tank wall, which rely on convection.
3 from the tank wall into the air, this is the role of relying on convection and radiation.
