Description
Technical field
The utility model relates to a kind of hyperchannel insulating oil on-line chromatograph analytical equipment, belongs to on-the-spot on-line monitoring technique field.
Background technology
By the dissolved gas content in the transformer oil is carried out gas chromatographic analysis, monitoring transformer operation conditions has been a kind of effective means of generally acknowledged guarantee transformer safe operation, but the shortcomings such as sampling operation is loaded down with trivial details, the effective difference of data that traditional laboratory stratographic analysis exists are difficult to realize the real-time oversight to running state of transformer.In recent years, transformer chromatogram monitoring technology is replenished and development as testing laboratory's analyzing and testing, because it has advantages of short, the continuous on-line monitoring of analytical cycle, can realize the on-line monitoring to transformer fault, its application is avoided the important effect of having of accident for the fault of timely discovery transformer.In addition, the on-line chromatograph monitor technology realizes that for transformer prophylactic repair excessively provides effective technical support to repair based on condition of component.Local supervising and measuring equipment is used for automatic collection, separation, detected characteristics gas composition content, usually is installed on the monitored equipment.Local supervising and measuring equipment generally is comprised of oil sample collecting device, gas and oil separating plant, automatic sampling apparatus, data acquisition unit.
Most of insulating oil on-line chromatograph analytical equipment on the market can only be analyzed a transformer now, and can not carry out stratographic analysis to many transformers, this device utilizes the sample introduction automatic transfer valve after degassed, through gas chromatography, data collection and analysis, realize many are detected in order near the Gases Dissolved in Transformer Oil of arranging.
The utility model content
The purpose of this utility model is for the shared gas chromatograph of the transformer of realizing many close together carries out the stratographic analysis of Gases Dissolved in Transformer Oil, to disclose a kind of hyperchannel insulating oil on-line chromatograph analytical equipment.
The technical scheme that its technical matters that solves the utility model adopts is: hyperchannel insulating oil on-line chromatograph analytical equipment is comprised of oil sample collecting device 1, gas and oil separating plant 2, auto injection transfer valve 3, gas chromatograph 5, data acquisition unit 6, carrier gas bottle 4, industrial computer 7; The input port of gas and oil separating plant 2 connects oil sample collecting device 1, and the output port of gas and oil separating plant 2 connects gas chromatograph 5 by auto injection transfer valve 3, gas chromatograph 5 connection data collectors 6, and connect industrial computer 7 by data acquisition unit 6; Carrier gas bottle 4 connects gas chromatograph 5 as auxiliary unit; The separating oil outlet connected tank of gas and oil separating plant 2; Gas and oil separating plant (2) comprises degasser and oil return apparatus.
The utility model hyperchannel insulating oil on-line chromatograph analytical equipment can connect altogether a gas chromatograph 5 and carry out the analysis of insulating oil on-line chromatograph overlap oil sample collecting device 1, gas and oil separating plant 2, auto injection transfer valve 3 more.
During the work of hyperchannel insulating oil on-line chromatograph analytical equipment, operation oil in the transformer is undertaken continuously by oil sample collecting device or periodically collection, the characteristic gas that then will be dissolved in the oil is separated into oil phase and gas phase by tripping device, isolated oil is back to oil tank of transformer by oil return apparatus, and oil dissolved gas is carried out stratographic analysis by the chromatograph sampling switching valve by artificial pre-set order, the result who analyzes extremely controls and processing unit by the data acquisition unit collection, data access industrial computer after will processing again carries out on-line monitoring by the monitoring software on the computing machine.
The beneficial effects of the utility model are that the utility model hyperchannel insulating oil on-line chromatograph analytical equipment not only can share a gas chromatograph and carry out the stratographic analysis of oil dissolved gas to the transformer of many close together; Can also in 500kV and the above transformer station near many single transformers of arranging, also can only make accurately quantitative test with this device to the oil dissolved gas composition.This device can be saved a large amount of purchase costs and manual maintenance workload, can widespread use in transformer operational application, fault diagnosis.
The utility model is applicable to the analysis of many close together Gases Dissolved in Transformer Oil on-line chromatographs.
