| 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, transformer power equipment, interior is filled with a lot of power, and partial discharge is easy to generate ozone, ozone is a kind of very high oxidizing substances, could easily lead to insulation materials by ozone oxidation decomposition, which is 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, transformer at run time, the internal is easy to produce a lot of heat, so that the thermal degradation in high polymer insulating materials, low molecular substance produced or escape, this is the common heat aging, thermal aging makes the insulating performance and mechanical performance of insulation material drops greatly. 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 a kind of aging is called aging environment, refers to the insulating materials in the light, oxygen, radiation and acid and alkali, the benefits of pollution caused by chemical reaction, and one of the most important factor is the ultraviolet ray in sunshine. 通过上面的分析,大家应该能够看出,变压器绝缘件的老化问题是不可避免的,我们能做的就是定期对变压器进行检查,在变压器绝缘件出现问题前提前进行更换,这样才能避免一些电力故障的出现。 Through the above analysis, we should be able to see that the transformer insulation aging is inevitable, we can do is to regularly check for transformer, the transformer insulation parts be replaced before it has problems, so as to avoid the occurrence of some power failures. |
