Abstract

The invention discloses a method for measuring the content of benzotriazole in transformer oil. The method comprises the following steps: preparing a standard solution; pretreating a sample by using lignin nano sol; carrying out surface enhanced Raman spectroscopy detection on the treated standard solution and the to-be-detected sample, and establishing a correction curve on the logarithm of the concentration of the benzotriazole by using the characteristic peak intensity of the benzotriazole at 1386cm <-1> in a surface enhanced Raman spectrogram of the standard solution, and calculating the content of benzotriazole in the to-be-detected sample according to the correction curve and the characteristic peak intensity at 1386cm <-1> in the surface enhanced Raman spectrum of the to-be-detected sample. The surface enhanced Raman spectrum detection technology is used for replacing traditional high performance liquid chromatography detection, the method is cleaner, more environmentally friendly and safer, and on-site detection can be achieved in combination with a portable Raman spectrometer while the detection sensitivity is guaranteed.

Description

technical field [0001] The invention relates to the technical field of transformer oil sample quality detection and analysis, in particular to a method for determining the content of benzotriazole in transformer oil. Background technique [0002] Transformer oil is an important insulating medium for oil-immersed electrical equipment in power systems. The quality and performance of oil products directly affect the safe operation of equipment and power grids. The quality supervision of transformer oil during equipment operation is an important task for power companies. Benzotriazole (BTA) is a common transformer oil additive, also known as benzotriazole. The heteroatoms in its molecule contain lone pairs of electrons, which are easy to combine with the d orbitals of metals to form coordination bonds, thereby A protective film is formed on the metal surface, which can prevent key metal parts such as winding coils and voltage regulating switch contacts inside the transformer fro...
