山东变压器油热循环的具体操作步骤!

发布时间2019-08-15  来源:http://www.wunqdctk.com

  变压器油热循环的具体操作步骤如下:
  The specific operation steps of transformer oil thermal cycle are as follows:
  1. 所述滤油器的进油管线连接到变压器底部的阀门上,所述滤油器的出油管线连接到变压器本体顶部的充油阀上;
  1. The oil inlet pipeline of the oil filter is connected to the valve at the bottom of the transformer, and the oil outlet pipeline of the oil filter is connected to the oil filling valve at the top of the transformer body.
  2. 开始的真空泵油过滤器,打开油油过滤器的进气阀,打开阀底部的变压器后抽真空注油口管的油过滤器,以饲料油油过滤器,进行自循环加热和油温。打开变压器顶部的注油阀,使注油管道内的空气通过真空泵排出,打开滤油器的注油阀进行热油循环加热。
  2. Starting with the vacuum pump oil filter, open the intake valve of the oil filter, open the transformer at the bottom of the valve, and then vacuum the oil filter of the oil injection pipe. The feed oil filter is used for self-circulating heating and oil temperature. Open the oil injection valve at the top of the transformer, so that the air in the oil injection pipeline is discharged through the vacuum pump, and open the oil injection valve of the oil filter for hot oil circulation heating.
  3.在连接滤油器的出油管道时,变压器本体顶部的充油阀上设有排气塞,用于排出管道内的气体。输油管道注满油后,打开变压器本体顶部的阀门进行热油循环。
  3. When connecting the oil outlet pipeline of the oil filter, an exhaust plug is arranged on the oil filling valve at the top of the transformer body for discharging the gas in the pipeline. After filling the oil pipeline, open the valve at the top of the transformer body for hot oil circulation.
  4. 在全油条件下热油循环前,检查吸湿器安装是否正确,呼吸是否顺畅。
  4. Before hot oil circulation under full oil condition, check whether the hygroscopicator is installed correctly and the breathing is smooth.
  5. 在热油循环过程中,滤油器出口油温不应低于50℃,油箱内温度不应低于40℃。热油循环后的油应取样检查,以满足交接试验标准。
  5. In the process of hot oil circulation, the oil temperature at the outlet of the filter should not be lower than 50 C, and the temperature in the tank should not be lower than 40 C. The oil after hot oil circulation should be sampled and inspected to meet the handover test standard.

  6. 热油循环完成后,应静置一段时间:110kV及以下不小于24小时,220、330kV不小于48小时,500kV不小于72小时。
  6. After the completion of the hot oil cycle, it should be stationary for a period of time: 110 kV and below not less than 24 hours, 220, 330 kV not less than 48 hours, 500 kV not less than 72 hours.
  7. 变压器静止后,从套管、升降座、冷却装置、气体继电器和压力释放装置排出几次废气,并启动潜油电泵,直至气体全部排出。
  7. After the transformer is stationary, exhaust gas is discharged several times from bushing, elevator, cooling device, gas relay and pressure release device, and the submersible electric pump is started until all the gas is discharged.
  8. 储油柜内的排气必须按照制造商的规定进行。
  8. The exhaust in the tank must be carried out in accordance with the manufacturer's regulations.
  以上步骤以胶囊式储油罐变压器为例。波纹管式储油罐无呼吸器。对热油循环操作步骤进行协商,制定专门的技术方案。
  The above steps take the capsule tank transformer as an example. Bellows type oil storage tank without respirator. Negotiate the operation steps of hot oil cycle and formulate special technical scheme.
  总之,变压器油的热循环应注意温度、阀门、静态、排气和油品的质量。
  In short, the thermal cycle of transformer oil should pay attention to temperature, valve, static, exhaust and oil quality.
