Embodiment Construction

[0027] The present invention is a full-automatic transformer oil chromatographic on-line monitoring device verification system, such as figure 1 As shown, it mainly includes two parts: the oil distribution system and the verification system. The oil dispensing process is fully automated, and the oil sample feeding link can realize multi-channel oil feeding, and prepare a variety of oil samples at the same time, such as low, medium and high concentration oil samples. The more types of oil samples, the larger the fuel tank. The needs to determine the preparation of the most several kinds of oil samples. The number of inlet standard gas channels can be the same as the number of oil sample types. For example, to prepare low, medium and high concentration oil samples, there are three channels to connect the oil tank with the standard gas bottle. After the standard gas is added, the oil-gas mixing cycle is carried out. After a period of time, the oil and gas are fully mixed, and th...

Abstract

The invention belongs to the technical field of electrical equipment, and particularly relates to a full-automatic check system for a transformer oil chromatography on-line monitoring device. The full-automatic check system is suitable for the accuracy and repeatability of the transformer oil chromatogram on-line monitoring device. The full-automatic check system comprises an oil distribution system and a verification system. According to the full-automatic check system, complete automation is achieved in the oil distribution and verification process, oil sample acquiring, gas loading, oscillation degassing and chromatography detecting and analyzing are all automatically completed by the system, errors brought by human factors are reduced, only component values of various gas of oil samples need to be preset, and the labor intensity is greatly reduced. Both wireless transmission and wire transmission can be adopted, the trouble of multiple connecting wires is eliminated, and therefore the working efficiency is obviously improved. The full-automatic check system further has the advantages of being small in floor area, easy to operate, high in detection precision and easy to achieve, has the extremely high application and popularization value and can be widely applied to units such as scientific research institutions and check and verification mechanisms.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a verification system for a fully automatic transformer oil chromatographic on-line monitoring device, which is suitable for the automatic verification system of the performance such as accuracy and repeatability of the transformer oil chromatographic on-line monitoring device. Background technique [0002] The transformer is the most important equipment in the power grid, and its safety is related to the stable operation of the entire power grid. The transformer will inevitably fail during operation. If the fault occurs inside the body, especially the latent fault, such as partial discharge, poor contact, etc., it will cause local overheating. When the heat reaches a certain level, the transformer oil will undergo a chemical reaction, resulting in a series of Hydrocarbon gases, typically CH 4 、C 2 h 2 、C 2 h 4 、C 2 h 6 etc., besides that, ther...
