[0002] The transformer oil chromatographic on-line monitoring device operating in the field needs to be tested regularly. However, the existing testing equipment is tested in the laboratory. Its volume is large, and the amount of stored oil is small, and its weight is not conducive to carrying on site. It is used for on-site testing. Most of them use open oil bags, which can only be stored for a short time, and the concentration will change after on-site transportation

Embodiment Construction
[0029] The present invention is an intelligent inspection and storage device for on-site oil chromatographic on-line monitoring device verification. It adopts the automatic control system with the Cortex-A8 processor of the ARM7 framework as the core and a special oil circulation structure. The ARM7 core chip is characterized by the ability to develop high performance and excellent power efficiency. The speed of the Cortex-A8 processor is in the range of 600MHz to over 1GHz, which is suitable for the requirements of mobile devices. The automatic control system stores the sample by controlling the independent piston, and the physical environment inside the chamber ensures the stability of the oil sample concentration.
[0030] Such as figure 1 As shown, the automatic control system of the present invention includes: a central processing part, an oil sample storage part, an oil sample circulation part, a sensor part and an oil circuit control part. Among them, the central proc...

The invention belongs to the technical field of online monitoring detection and especially relates to detection on transformer oil chromatogram online monitoring devices, in particular to an intelligent inspection storage device used for verification of an on-site oil chromatogram online monitoring device. The intelligent inspection storage device comprises an automatic control system of an ARM7 framework and taking a Cortex-A8 processor as a core as well as an oil circuit circulating structure, and speed of the Cortex-A8 processor is in a range of 600MHz to higher than 1GHz, thereby being applicable to operating requirements of mobile equipment. An independent piston type storage sample is controlled by virtue of the automatic control system, and a physical environment inside a cavity guarantees stable oil sample concentration; and a cyclic detection mode and a non-cyclic detection mode greatly reduce weight of a complete machine, so that the intelligent inspection storage device canbe conveniently carried to a site to perform detection. The intelligent inspection storage device provided by the invention is applicable to detection on oil chromatogram online monitoring devices ofall kinds of structures, with all kinds of models and manufactured by all kinds of factories and can automatically adjust oil level and automatically circulate, so that escaped gas can be fused into oil again, and the intelligent inspection storage device is applicable to verification on all kinds of sites.
