达不到标准值的油会发生渗油故障

  变压器油如果经常过热运行或进水、吸收潮气,将使油质变坏。使用达不到标准值的油,很容易在绕组与外壳之间发生击穿放电,造成严重事故。

  If the transformer oil runs too often, or if it runs or absorbs moisture, it will deteriorate the oil quality. It is very easy to break through the discharge between the windings and the shell by using the oil which is not up to the standard value, causing serious accidents.

  发现变压器漏油要及时处理,如渗漏油严重,应及时将变压器停止运行并进行检修。检查时首先寻找漏油点,漏油故障比较容易发现,渗油故障则不易发现,一般在尘土聚集且潮湿的地方渗油。

  It is found that the leakage of transformer must be dealt with promptly, such as serious leakage of oil, so the transformer should be stopped and repaired in time. First of all, we should look for the oil leakage point. It is easy to find the oil leakage fault. Oil leakage is not easy to find. Oil seepage is usually done in the place where dust is gathered and wet.

  若变压器油从上端盖上渗出时,应紧固上端一圈螺丝;若变压器油从挡位处渗出时,就应打开挡位盖,拧紧里边的压紧螺丝;若绝缘垫老化时,就应及时更换绝缘油垫。

  If the transformer oil is exuded from the upper cover, a screw should be fastened at the upper end. If the transformer oil is exuded from the gear position, it should open the retaining cover and tighten the pressure screw in the inside. If the insulation pad is aging, the insulating oil pad should be replaced in time.

  变压器油在使用1~3年时应做一次耐压试验。如果变压器油达不到技术要求,应尽早更换或过滤。由于对变压器油的质量要求很高,不经过耐压试验和简化试验很难说明变压器油是否合格,但经过长期的实践来看,变压器油的合格与否可通过一闻、两看来鉴别。

  Transformer oil should be subjected to a voltage withstand test for 1~3 years. If transformer oil is not up to the technical requirements, it should be replaced or filtered as early as possible. Because the quality of transformer oil is very high, it is difficult to explain whether transformer oil is qualified without pressure test and simplified test. But after long-term practice, the qualification of transformer oil can be identified by one smell and two.

  尽量控制变压器上层油温不超过85摄氏度,即要求与室温之差低于55摄氏度。如果变压器在运行时,油温突然升高,则是变压器内部过热的表现。外部原因是变压器严重过负荷;内部原因有铁芯着火、绕组匝间短路、内部螺丝松动、冷却装置故障等。

  Try to control the upper layer of transformer oil temperature is not more than 85 degrees Celsius, that is, the difference between the requirement and room temperature is less than 55 degrees Celsius. If the transformer temperature rises suddenly when the transformer is running, it is the performance of the transformer's internal overheating. The external reason is that the transformer is seriously overloaded. The internal causes include iron core ignition, winding turn to turn short circuit, internal screw loosening, and cooling device failure.

  新的变压器油一般是浅黄色,氧化后颜色会变暗。二看变压器油的透明度。新的变压器油装在玻璃瓶中是透明的,并带有蓝紫色的荧光,如果失去了荧光或不再透明,说明变压器油内已有游离碳和机械杂质。

  The new transformer oil is usually yellowish, and the color will darken after oxidation. Two see the transparency of transformer oil. The new transformer oil is transparent in glass bottles and has a blue and purple fluorescence. If the fluorescence is lost or no more transparent, there are free carbon and mechanical impurities in the transformer oil.
