Abstract

The invention discloses transformer oil with the gas inhibition function. The transformer oil is prepared from, by weight, 80-95% of naphthenic base oil, 0.05-2% of a free radical scavenger and 0.5-2% of a nano-additive, wherein the free radical scavenger is a dithiocar-bamate free radical scavenger or a thiazole free radical scavenger or a sulfenamide free radical scavenger, and the nano-additive is one of nano-alumina and nano-aluminum nitride. The transformer oil has the obvious gas inhibition effect, gas generation in the transformer oil can be obviously inhibited, and thus the service life of the transformer oil can be prolonged.

Description

technical field [0001] The invention relates to a transformer oil with gas suppression function and a preparation method thereof. Background technique [0002] At present, most of the high-voltage and large-capacity power transformers at home and abroad adopt oil-filled transformers. This type of transformer adopts an oil-paper composite insulation structure mainly composed of insulating oil and insulating paper (board), and has high electrical strength. During long-term operation, the insulating oil and other insulating materials in the transformer will gradually age and decompose under the action of electricity and heat, producing low molecular hydrocarbons, CO and CO 2 These gases will dissolve in the insulating oil. When the transformer is in normal operation, the external electrical, thermal and mechanical stresses are not enough to destroy the chemical bonds of insulating oil and insulating paper, and the normal aging of insulating materials only decomposes to produce...
