冬季是否应该加强对变压器油的维护?

发布时间2019-04-02  来源:众彩彩票注册http://www.wunqdctk.com

变压器油在变压器中起增强绝缘、加快散热、防腐和灭弧的作用。变压器在运行中如果漏油、油位过高或过低、油温异常、油色变化等都属于不正常现象,若疏于管理,让其继续运行,可能会造成停电、设备损坏,甚至引起火灾。因此,在冬季应加强对变压器的运行管理。
  Transformer oil plays the role of enhancing insulation, accelerating heat dissipation, anti-corrosion and arc extinguishing in transformers. Transformer in operation if oil leakage, oil level is too high or too low, abnormal oil temperature, oil color change and other abnormal phenomena, if neglected management, let it continue to operate, may cause power outages, equipment damage, or even fire. Therefore, the operation and management of transformers should be strengthened in winter.
  冬季到了,由于天气寒冷,户外气温低,变压器中的变压器油油位一般会下降,当油位低于油位表的低限刻度时,应及时加油。
  Winter is coming. Because of the cold weather and low outdoor temperature, the oil level of transformer oil in transformer will generally decrease. When the oil level is lower than the low calibration of oil level meter, it should be refueled in time.
  山东变压器油的管理中还应该注意以下常见问题。
  The following common problems should be noted in the management of transformer oil in Shandong Province.
  1、防止变压器油位过低
  1. Preventing Transformer Oil Level from Too Low
  变压器正常运行时油位的上升或下降,是由温度变化造成的,油位变化不会太大。当油位下降显著,甚至从油位计中看不见油位,则可能是因为变压器出现了漏油、渗油现象,这往往是因为变压器油箱损坏、放油阀门没有拧紧、变压器顶盖没有盖严、油位计损坏等原因造成的。油位太低会加速变压器油的老化,变压器绝缘情况恶化,所以要多巡视,多维护,及时添油。
  The rise or fall of oil level in normal operation of transformer is caused by the change of temperature, and the change of oil level will not be too big. When the oil level drops dramatically, even the oil level can not be seen from the oil level gauge, it may be due to transformer oil leakage, oil leakage phenomenon, which is often caused by transformer tank damage, unloading valve not tightened, transformer top cover not tightened, oil level gauge damage and other reasons. Too low oil level will accelerate the aging of transformer oil and deteriorate the insulation condition of transformer. Therefore, more inspection, maintenance and timely refueling are needed.
  2、观察变压器是否漏油
  2. Observe whether the transformer leaks oil
  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。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。
  It is found that the oil leakage of transformer should be treated in time. If the oil leakage is serious, the transformer should be stopped and repaired in time. When inspecting, the first step is to find the oil leakage point. The oil leakage fault is easy to find, but the oil leakage fault is not easy to find. Generally, oil leakage occurs in the dust-gathered and humid areas. If the transformer oil seeps out from the upper cover, a ring of screw should be tightened; if the transformer oil seeps out from the retaining position, the retaining cover should be opened and the pressing screw inside should be tightened; if the insulating cushion is aging, the insulating oil cushion should be replaced in time.
  3、一闻两看辨别变压器油质量
  3. Distinguishing Transformer Oil Quality with One Smell and Two Views
  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 tested once for 1 to 3 years. If the transformer oil does not meet the technical requirements, it should be replaced or filtered as soon as possible. Because of the high quality requirement of transformer oil, it is difficult to explain whether the transformer oil is qualified without voltage withstanding test and simplified test. However, after long-term practice, whether the transformer oil is qualified or not can be identified by one smell and two looks.
  一闻:就是通过闻气味来鉴别变压器油质量,合格的变压器油应没有气味,或略带一点煤油气味。若有别的气味,说明油质变坏。
  Smell: It is to identify the quality of transformer oil by smelling. Qualified transformer oil should be odorless or slightly kerosene. If there are other odors, it means that the oil is deteriorating.
  两看:一看变压器油的颜色。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。

  Two look: one look at the color of transformer oil. The new transformer oil is usually light yellow, which will darken after oxidation. Second, look at the transparency of transformer oil. The new transformer oil is transparent in glass bottle and has blue-purple fluorescence. If the fluorescence is lost or no longer transparent, it indicates that there are free carbon and mechanical impurities in the transformer oil.
  4、及时添加变压器油
  4. Add transformer oil in time
  冬季由于天气寒冷,变压器的油位一般会下降,油标无显示时应及时将油添加到油位线。给运行中的变压器补油时应注意,35千伏及以上变压器应补入相同牌号的油,并且作耐压试验;10千伏及以下变压器可补入不同牌号的油,但应作混油耐压试验。
  Because of the cold weather in winter, the oil level of transformer will generally decrease. When the oil mark is not displayed, oil should be added to the oil level line in time. When refueling transformers in operation, it should be noted that transformers with 35 kV or more should be supplied with the same brand of oil and made voltage withstand test. Transformers with 10 kV or less can be replaced with different grades of oil, but should be tested for mixed oil withstand voltage.
  5、检查箱顶油面温度计温度
  5. Check the temperature of oil surface thermometer on the top of tank
  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。
  As far as possible, the oil temperature of the upper layer of the transformer should not exceed 85 degrees Celsius, that is, the difference between the oil temperature and the room temperature should be less than 55 degrees Celsius. If the oil temperature of the transformer suddenly rises when it is in operation, it is the manifestation of overheating inside the transformer. External causes are transformer serious overload; internal causes include core ignition, winding turn-to-turn short circuit, internal screw loosening, cooling device failure, etc.
  6、及时处理变质的变压器油
  6. Handling Deteriorated Transformer Oil in Time
  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。
  Transformer oil will deteriorate if it is often overheated or water intake and moisture absorption. It is easy to break down and discharge between winding and shell when using oil that can't reach the standard value, resulting in serious accidents.
