Embodiment 1

[0024] Preparation of Very Low Standard Oil Samples:

[0025] First, determine the target concentration oil sample, and calculate the required oil volume and standard gas content according to the target concentration through the oil sample preparation formula.

[0026] 1

[0027] Degassing is carried out by vacuum degassing, and the obtained blank transformer oil concentration is:

[0028] 1

[0029] The prepared blank oil sample is injected into a variable-volume sealed container with a rubber gas injection pad through a closed pipeline.

[0030] Inject the calculated standard gas into the airtight container containing the blank oil sample.

[0031] Put the above-mentioned airtight container containing the blank oil sample and standard gas into a high-temperature box at 50°C, and turn on the power circulation pump for 24 hours. Oil test:

Abstract

The invention discloses a preparation method for a standard transformer oil sample. The preparation method comprises the steps of quantifying a blank oil sample, degassing the blank oil sample, injecting the blank oil sample into a sealed container, adding quantified gas, fully mixing the quantified gas and the blank oil sample and the like to prepare the standard oil sample of the transformer. The standard transformer oil sample prepared by the method disclosed by the invention can be used as an oil sample standard for standard transmission from the national level to the local level, so that a detection standard can be easily implemented in reality. The preparation method particularly has an obvious standard oil sample effect on extremely high concentration and extremely low concentration.

Description

technical field [0001] The invention relates to a method for preparing standard transformer oil samples, in particular to the method for preparing standard transformer oil samples with extremely low concentration and extremely high concentration. Background technique [0002] In the national "Twelfth Five-Year" development plan, the construction of smart grid is regarded as a key strategic development plan. The construction of smart grid can be divided into six independent but interrelated links: smart power generation, smart power transmission, smart power transformation, smart power distribution, smart power consumption and smart dispatch. Among them, both the intelligent power generation link and the intelligent substation link are inseparable from important core power equipment: transformers and reactors. As two important equipment in power generation and substation, their safe and stable operation is directly related to the safety and stability of the national grid sys...
