General knowledge of ZYD series transformer insulating oil filter and oil filter involved in box transformer and main transformer

2020/1/19??????view:

  1、 What is transformer oil?

  Transformer oil: it is a kind of fractionation product of petroleum. Its main components are alkane, cycloalkane saturated hydrocarbon, aromatic unsaturated hydrocarbon and other compounds. Commonly known as square shed oil, light yellow transparent liquid, relative density 0.895. Freezing point < - 45 ℃.

  Transformer oil is a kind of mineral oil obtained from distillation and refining of natural oil. It is a mixture of natural hydrocarbon which is pure, stable, low viscosity, good insulation and good cooling property. Commonly known as square shed oil, light yellow transparent liquid.

  2、 Common sense of box transformer and main transformer.

  Transformer is an important electrical equipment with large investment in the power system. Insulating oil acts as the medium of transformer insulation and heat dissipation, which is closely related to various faults that may occur inside the transformer. The condition of insulating oil will directly affect the safe and economic operation of the transformer, and the vacuum oil filter of the transformer is a powerful tool for insulating oil treatment.

  Box type transformer - main transformer (transformer) needs oil filtering treatment to improve its purity if the electrical index of transformer oil quality is unqualified due to various reasons. The main unqualified reasons are excessive water content, other impurities, hydrocarbon gas, etc.

  3、 General knowledge of ZYD series transformer insulating oil filter

  ZYD series transformer insulating oil filter and oil purifier can be selected according to different voltage levels of the transformer.

  1. Zhongjing brand ZY type insulating oil vacuum oil filter is generally used to filter the insulating oil of box type transformer. After filtering, the oil withstand voltage grade is 45-65kv, which is suitable for filtering and purification of most commonly used electrical insulating oil and transformer oil.

  2. Zhongjing brand ZYD two-stage vacuum oil filter is selected to purify the insulating oil of 110kV and above main transformer, which can reach the oil standard after purification. For the transformer oil of the main transformer, in addition to the reference of oil withstand voltage value, the general oil filtering index also takes into account the influence of acetylene, methane, hydrogen and other gas values, as well as the influence of dielectric loss. In this way, the air content and water content of transformer insulating oil can be reduced more successfully, the electrical insulation strength of oil can be significantly improved, and the insulation performance is stable.

  If considering that the transformer has been filled with oil and can not be completely shut down and pumped out all oil for filtering, it can only filter oil online. In addition, it can reduce the equipment outage time, reduce the maintenance labor intensity and operation cost, improve the service life and reliable operation rate of the transformer, and adopt the working mode of small flow and low vacuum to eliminate the possibility of oil flow electrification and gas action, which has good economic benefits and promotion value.

  On line oil filter of transformer shall meet the following conditions:

  (1) If the heating temperature is too high, the characteristics of the oil will be damaged; if the temperature is too low, the water in the oil can not be discharged, so the temperature and vacuum value should be controlled within the appropriate range in the oil treatment process.

  (2) During the operation of on-line oil filtering device, it is necessary to ensure that there will be no result of oil flow electrification in the transformer and no signal or trip accident caused by the action of non electric quantity protection device of the transformer.

  (3) In case of abnormal voltage or oil leakage during oil filtering, the online oil filtering system can effectively isolate the oil circuit and power failure alarm, and has the function of remote operation status detection and control during oil filtering.

  (4) The on-line oil filtering device will not produce fault characteristic gas due to its own reasons.

  (5) In the process of on-line oil filtration, it can Degas, dehydrate and remove impurities, and maintain the good insulation property and stability of oil.
