Abstract

The invention provides a spot simulation device for fault oil products of a transformer, comprising a temperature control system composed of an electric heater, and a piston type expander, wherein an electrode point pressure gauge is arranged at the top of an oil storage tank; the electrode of the electrode point pressure gauge is connected on a power supply loop of the heater; the electric heater is arranged in the oil storage tank and / or on an upper pipeline of the oil storage tank; a temperature sensor is arranged on the side wall of the oil storage tank; a circulating pump is arranged between the upper pipeline of the oil storage tank and a bottom pipeline of the oil storage tank; an oil sample inlet of the transformer is arranged on the upper pipeline of the oil storage tank; the bottom pipeline of the oil storage tank is provided with a standard gas sample inlet and a sampling pipe; the sampling pipe is provided with a sampling valve; and the piston type expander is communicated with the oil storage tank through the top of the oil storage tank. Through quantitatively adding the transformer oil and standard gas to the oil storage tank, heating and circulating at a constant temperature, the oil and the gas are balanced so as to form the standard oil sample containing standard gas component value; and the oil sample is finally used for the spot detection of an online chromatograph.

Description

technical field [0001] The invention relates to a standard oil sample generation device containing standard gas composition values, specifically adding standard gas quantitatively into a closed device equipped with transformer oil to form an oil-gas mixing device containing standard gas composition for use in on-line chromatography Instrument calibration in the laboratory and on-site. Background technique [0002] Using chromatographic analysis technology to judge the internal latent faults of transformers is a method recognized at home and abroad, mature and widely used, and it is an important means to ensure the safe operation of transformers. However, there is no mature method for the calibration of online chromatographs widely used in substations, and there is no standard oil sample with fixed standard gas composition values, so it is impossible to judge the operating conditions of online chromatographs and the accuracy of data.
