Embodiment Construction

[0017] The present invention will be further described below in conjunction with specific embodiments.

[0018] A transformer oil consisting of the following components by weight:

[0019] Antioxidant 0.05%

[0020] Surfactant 0.03%

[0021] BN nanoparticles 0.03%

[0022] The balance is transformer base oil.

[0023] Further, the transformer base oil is paraffin-based or naphthenic mineral oil.

[0024] Preparation method of transformer oil:

[0025] 1) Put BN nanoparticles and surfactant into an organic solvent and fully mix and stir;

[0026] 2) Add the product in step 1) into the transformer base oil, fully stir in a water bath at 40°C until the organic solvent is completely volatilized, then ultrasonically oscillate for 1 hour, and stand to obtain stable larvae with evenly dispersed BN nanoparticles;

[0027] 3) drying to remove water;

[0028] 4) Add white clay, adsorb at 120°C to 135°C for 2.5 hours at high temperature, and then finely filter;

[0029] 5) adding...

Abstract

The invention discloses a transformer oil and a preparation method thereof. The transformer oil comprises the following components by weight: 0.05% of an antioxidant, 0.03% of a surfactant, 0.03% of BN nanoparticles and the balance of transformer base oil. The invention has the beneficial effects of substantially improving thermal conductivity and breakdown performance of the transformer oil, and at the same time increasing the dielectric strength of the transformer oil.

Description

technical field [0001] The invention relates to a transformer oil and a preparation method thereof, in particular to a transformer oil with high thermal conductivity and a preparation method thereof. Background technique [0002] The main functions of transformer oil are: (1) Insulation, transformer oil has a much higher dielectric strength than air. Immersing the insulating material in oil can not only improve the insulation strength, but also protect it from moisture erosion. (2) Heat dissipation: Transformer oil has a large specific heat and is often used as a coolant. The heat generated during the operation of the transformer causes the oil close to the iron core and winding to expand and rise. Through the convection of the oil up and down, the heat is dissipated through the radiator to ensure the normal operation of the transformer. (3) Arc suppression effect: On the oil circuit breaker and the on-load tap changer of the transformer, an arc will be generated when the c...
