1、变压器是电力设备,内部充满了大量的电力,而局部放电容易产生臭氧,臭氧是一种氧化性非常高的物质,很容易导致绝缘件材料被臭氧氧化裂解,这就是电老化。
1, the transformer is the power equipment, the internal is filled with a lot of power, and partial discharge is easy to produce ozone. Ozone is a highly oxidizing material, which is easy to cause the insulation materials to be oxidized by ozone, which is electrical aging.
2、除了电老化之外,还有热老化,变压器在运行的时候,内部很容易产生大量的热量,从而使高分子绝缘材料发生热降解、低分子物产生或逸出,这就是常见的热老化,热老化会使绝缘材料的绝缘性能和机械性能大大下降。
2, in addition to electrical aging, and thermal aging, in the operation of the transformer when the internal is easy to generate a lot of heat, so that the polymer produced or out of thermal degradation of insulation materials, low molecular materials, this is the common heat aging, thermal aging will make the insulation properties and Mechanical properties of insulating materials is greatly reduced.
3、还有一种老化叫做环境老化,是指绝缘材料在光、氧、辐射和酸碱等因素的作用下而引起的污染性化学反应,而其中最主要的因素是阳光中的紫外线。
3, there is also an aging called environmental aging, which refers to the chemical reaction caused by the factors of light, oxygen, radiation and acid and alkali, and the most important factor is ultraviolet in the sunlight.
