Description

technical field [0001] The invention relates to the technical field of substations, in particular to a self-produced carrier gas device for oil chromatography on-line monitoring carrier gas cylinders. Background technique [0002] With the increasing scale of the power grid, the oil-filled main transformer high oil resistance chromatographic on-line monitoring devices of substations are gradually increasing, and the oil-filled main transformer high oil resistance chromatographic on-line monitoring devices have occupied a more important position. The oil chromatography on-line monitoring system is a precision equipment integrating control, measurement and analysis technology, and the oil chromatography on-line monitoring device can accurately reflect data changes, which has become one of the important indicators for judging the high-resistance operation status of the main transformer. The oil-filled main transformer high-resistance oil chromatography online monitoring device ...

AI Technical Summary

Problems solved by technology

Substation oil-filled main transformer high resistance oil chromatographic on-line monitoring device cannot automatically generate carrier gas due to the low pressure of the carrier gas cylinder, resulting in the outage of the oil chromatographic on-line monitoring device

[0003] Currently, the carrier gas of the oil chromatography on-line monitoring device is an external nitrogen cylinder, but due to the long-term operation of the oil chromatography on-line monitoring device, the amount of carrier gas is large, so that the pressure of the carrier gas bottle is not enough and the device is shut down

Therefore, when it is necessary to grasp the status of the main equipment in real time, it is necessary to pay close attention to the amount of carrier gas and frequently replace the carrier gas cylinder, which increases the operating cost of the substation and the workload of operation and maintenance personnel
