Abstract

The invention relates to a measuring instrument for trace moisture in oil. The measuring instrument for trace moisture in oil adopts a physical measuring method to measure trace moisture in oil, and has no need for chemical reagent, no chemical reaction, no toxic hazard to operation staff, no environmental pollution, and low operation cost, thus realizing a whole measuring process of green environmental protection. The measuring instrument of the invention has simple operation and no need for preparing and storing chemical reagents, and can automatically realize quantitative sampling, oil-moisture separation, moisture vaporization, moisture measuring, as well as trace moisture content calculation.

Description

technical field [0001] The invention relates to an instrument for measuring trace moisture in oil, in particular to a physical measuring device for measuring trace moisture in transformer oil. Background technique [0002] Theoretically, micro-water in transformer oil mainly exists in transformer insulating oil in the form of free, dissolved and emulsified. The higher the temperature, the stronger the ability to dissolve water in the transformer oil, and the more water can be dissolved. At 0°C, the water dissolves 0.02 g / kg, and at 100°C, it is 0.8 g / kg_l. Since the temperature of the transformer is 80-100°C during operation, the solubility of water is very high. In actual operation, the water is evenly present in the transformer insulating oil in the form of dissolution. Only when the transformer stops running, the temperature drops and it is in a supersaturated state, the moisture in the transformer oil mainly exists in the bottom of the oil tank in the form of free. Wit...
