防止山东变压器油被污染的主要原因有哪些?

  1. 在真空注油过程中,要定期清洗真空注油罐和用来固定变压器及变压器本体的“吊篮”,使其保持清洁状态。通常情况下,“吊篮”不能放在地面上,以免泥土从地面进入真空油箱。真空油箱和“吊篮”的清洗方法,是用“丝”或布擦去不容易擦去的旧油,可用手提式铜丝刷或刮刀清除。清洗时,防止灰尘和纤维留在真空灌装箱或“吊篮”内。
  1. In the process of vacuum oil filling, the vacuum oil filling tank and the "basket" used to fix the transformer and the transformer body shall be cleaned regularly to keep them in a clean state. Usually, the "basket" should not be placed on the ground to prevent soil from entering the vacuum tank from the ground. The cleaning method of vacuum oil tank and "basket" is to use "silk" or cloth to wipe off the old oil that is not easy to wipe off, which can be removed with a portable copper wire brush or scraper. When cleaning, prevent dust and fibers from remaining in the vacuum filling box or "basket".
  2、变压器、变压器油箱,油箱,陶瓷套管,如内部,并安装在变压器内部零件,装配之前,根据工艺要求干净,特别注意检查石油储罐的焊接和油箱内部,可以没有飞溅,油箱底部放油的管不应在泥土上。导尿管应保持清洁。
  2. Transformer, transformer oil tank, oil tank, ceramic sleeve, such as inside, shall be installed on the internal parts of transformer. Before assembly, they shall be clean according to the process requirements. Pay special attention to check the welding of oil tank and the internal part of oil tank. There can be no splash. The oil drain pipe at the bottom of oil tank shall not be on the soil. The catheter should be kept clean.
  3、做好变压器工作,变压器铁芯硅钢片生锈、生锈。在硅钢片的加工和贮存过程中,要做好防锈工作,尽可能缩短硅钢片剪切成型后的贮存时间,同时进行加工。铁芯堆放后,在变压器、互感器绕组覆盖之前,必须对铁芯进行反复、仔细的清洗,清除铁芯表面的锈垢。铁芯、卷绕装配后的仪器,要及时加油处理,尽量缩短铁芯在空气中的暴露时间。最好将铁芯在装配后清洗干净,在铁芯表面及时涂上专用的防锈涂料,这样才会更有效地防止铁芯生锈。
  3. Do a good job in transformer work. The silicon steel sheet of transformer core is rusted. In the process of processing and storage of silicon steel sheet, rust prevention should be done well, and the storage time after shear forming of silicon steel sheet should be shortened as much as possible, and processing should be carried out at the same time. After the iron core is stacked, before the transformer and transformer windings are covered, the iron core must be cleaned repeatedly and carefully to remove the rust on the surface of the iron core. After the assembly of iron core and winding instrument, oil shall be added in time to shorten the exposure time of iron core in the air as much as possible. It is better to clean the iron core after assembly and apply special antirust coating on the surface of the iron core in time, so as to prevent the iron core from rusting more effectively.
  4. 做好变压器、变压器总成车间和绕线车间的文明生产工作,保持车间清洁、防尘、防潮。
  4. Do a good job in civilized production of transformer, transformer assembly workshop and winding workshop, and keep the workshop clean, dust-proof and moisture-proof.
  5. 对机体的绝缘板和绝缘材料进行来料检验,防止绝缘材料质量不佳,对绝缘油造成污染。最简单的试验是将一小块绝缘材料样品浸入合格的绝缘油瓶中。几天后,对绝缘油的介电损耗系数(tg 90°c)进行分析。均匀做绝缘材料与油的相容性试验,使材料与油达到相容程度。
  5. Carry out incoming inspection on the insulating board and insulating materials of the machine body to prevent the poor quality of insulating materials from polluting the insulating oil. The simplest test is to dip a small sample of insulating material into a qualified insulating oil bottle. After a few days, the dielectric loss coefficient (TG 90 ° C) of insulating oil was analyzed. Make the compatibility test of insulating material and oil evenly to make the material and oil reach the compatibility degree.
  6. 阀体应严格按照工艺要求进行真空注油或热风循环干燥处理。对热空气进行净化,消除热空气对仪表变压器本体和仪表变压器本体的污染。仪表变压器和变压器的注油必须采用真空注油法。
  6. The valve body shall be subject to vacuum oiling or hot air circulation drying treatment in strict accordance with the process requirements. Clean the hot air to eliminate the pollution of the instrument transformer body and the instrument transformer body. The instrument transformer and transformer must be filled with vacuum oil.
  7. 保持变压器及变压器本体的清洁。严禁将尸体暴露或存放于地面。机体完成后,应盖上专用盖或用专用布盖住,以防止水、灰尘等侵入机体。
  7. Keep the transformer and its body clean. It is strictly forbidden to expose or store the body on the ground. After the machine body is completed, it shall be covered with a special cover or with a special cloth to prevent water and dust from invading the machine body.
  8. 变压器和互感器浸油后,在将变压器本体和互感器组装进油箱之前,应使用清洁的绝缘油对变压器本体和互感器进行清洗,避免将脏东西带入变压器内部。真空充油处理后安装在油箱内的变压器应及时充油,避免长期暴露在空气中。
  8. After the transformer and mutual inductor are immersed in oil, before assembling the transformer body and mutual inductor into the oil tank, clean the transformer body and mutual inductor with clean insulating oil to avoid bringing dirt into the transformer. The transformer installed in the oil tank after vacuum oil filling treatment shall be filled with oil in time to avoid long-term exposure to the air.
  9. 变压器和互感器在装配时,应做好保护工作。
  9. When assembling the transformer and transformer, the protection work shall be done well.
