The invention is applicable to the technical field of dissolved gas monitoring, and provides a predicting method of dissolved gas volume percent in oil and a terminal device. The method includes stepsof acquiring volume percent of gas components in a gas room at a first time point, a second time point and a third time point under a non-balance state; calculating the volume percent of the gas component in the gas room under the balance state according to the volume percent corresponding to the first time point, the volume percent corresponding to the second time point, the volume percent corresponding to the third point and the volume percent predicting formula. According to the volume percent of the gas component collected for many times under the non-balance state, the final value of thevolume percent of the gas component in the gas room under the balance state can be predicted; it is unnecessary to measure the volume percent of gas in the gas room after permeating to enter the balance state, thus time required to measure the volume percent of the dissolved gas in the oil is reduced.
Description
technical field [0001] The invention belongs to the technical field of dissolved gas monitoring, in particular to a method for predicting the volume fraction of dissolved gas in oil and terminal equipment. Background technique [0002] With the development of the power grid in the direction of high automation and the increasing requirements for the reliability of power supply for the national economy and the people's livelihood, it is urgent to reform the current equipment maintenance system, and the condition-based maintenance system based on online monitoring and fault diagnosis technology gradually replaces preventive maintenance. The development trend of the system has become inevitable. From the perspective of the importance of the reliability of oil-filled power equipment such as transformers and the price of traditional on-line monitoring devices, the use of on-line monitoring devices has significant advantages in technology and economy, which not only improves the ma...
