With the adoption of the technical scheme, the oil color spectrum online monitoring device provided by the utility model uses a broad spectrum type gas phase color spectrum analysis basic principle to carry out online monitoring and accurate analysis on fault characteristic gas, such as hydrogen, carbon monoxide, methane, ethane, ethylene, acetylene, carbon dioxide and the like, in oil for electromechanical equipment, so that fault information of the electromechanical equipment can be captured in time. Therefore, the equipment operation and maintenance can be scientifically guided, and the safe operation of an electric power system can be ensured.
Description
Technical field
The utility model belongs to the Hydraulic and Hydro-Power Engineering field, and particularly a kind of power station and pumping plant oil system are used the oil chromatography on-Line Monitor Device.
Background technology
Oil system is one of main backup system in power station, and large hydropower station can reach hundreds of tons and even thousands of tons of with oil mass, and medium waterpower generator station and pumping plant also have tens of tons to hundreds of tons.In order to guarantee that so a large amount of oil of using maintains good user mode, to accomplish its various tasks, needs carry out on-line monitoring to oil system in good time.Present most of power station and pumping plant still adopt conventional manual detection mode to the monitoring of oil system, and its sense cycle is longer, can not in time capture the electromechanical equipment failure message, to such an extent as to be unfavorable for the maintenance of scientific guidance equipment operation.
Summary of the invention
The technical matters that the utility model will solve is: provide a kind of and can in time capture the electromechanical equipment failure message; So that scientific guidance equipment operation maintenance; The power station and the pumping plant oil system that guarantee safe operation of power system are used the oil chromatography on-Line Monitor Device, to overcome the deficiency of prior art.
The utility model is to constitute like this: it comprises oil-gas separator 1, cold-trap 2, carrier gas regulation and control system 3, demand chamber 4, chromatogram detecting unit, gas sensor 5, CPU6, main control computer 7; Oil-gas separator 1 is connected with the demand chamber that is connected with carrier gas regulation and control system 34 behind cold-trap 2; The outlet of demand chamber 4 connects the chromatogram detecting unit; The chromatogram detecting unit connects CPU6 behind gas sensor 5, CPU6 is connected with main control computer 7 through communication network.
Above-mentioned power station and pumping plant oil system are with in the oil chromatography on-Line Monitor Device, and described chromatogram detecting unit is to be made up of chromatographic column 8 and pid number temperature-controlling system 9.
Owing to adopted technique scheme; Compare with prior art; The utility model adopts oil-gas separator, cold-trap, carrier gas regulation and control system, demand chamber, chromatogram detecting unit, gas sensor, CPU composition data collector; Utilization broad spectrum type gas chromatographic analysis ultimate principle can be made on-line monitoring and accurately analysis with fault characteristic gas in the oil to electromechanical equipments such as hydrogen, carbon monoxide, methane, ethane, ethene, acetylene and carbon dioxide, and then can in time capture the electromechanical equipment failure message; So that the maintenance of scientific guidance equipment operation guarantees safe operation of power system.
