Problems solved by technology

[0005] During the preparation of natural ester insulating oil, the main residual impurities include trace conductive substances and residual bound water, and conductive substances are also polar substances, but the inventors found that: the existing high-stable super-hydrophilic adsorption The agent is used to remove the residual conductive substances and residual bound water in the natural ester insulating oil. It is easy to introduce new impurities in the process of advanced treatment, and it is difficult to ensure that the natural ester insulating oil maintains its own properties after it is put into operation.

Abstract

The invention relates to an advanced treatment process of natural ester insulating oil, a super-hydrophilic adsorbent and a preparation method and application of the super-hydrophilic adsorbent, and particularly relates to a preparation process of a high-stability silicon oxide adsorbent and an application mode of the super-hydrophilic adsorbent. The invention also discloses a process for improving the pressure resistance and dielectric loss of the natural ester insulating oil and reducing the indexes such as acid value, pour point and kinematic viscosity. According to the invention, various types of commercially available natural ester insulating oil are subjected to deep treatment, so that residual polar substances and bound water in the natural ester insulating oil are effectively reduced, and the initial indexes and stability of the natural ester insulating oil are improved. The super-hydrophilic adsorbent has strong stability, and does not introduce new impurities into the oil while removing various impurities in the natural ester insulating oil, thereby avoiding the change of the properties of the oil. According to the process, various initial properties and operation stability of the natural ester insulating oil are fully improved, meanwhile, the range of treatment objects is wide, the process stability is high, and the process shows great application potential.
