By combining three degasification methods with the method of an off-line chromatographic instrument to form a mobile whole body, the mobile monitoring equipment disclosed by the utility model can be quickly put into operation on site in time for catching faults of the equipment so as to realize automation and intelligentization in the overall process and guarantee safe operation of the equipment; meanwhile, the results of the three degasification methods are compared with the result of the off-line chromatographic instrument so as to realize good fault diagnosis of the transformer.
Description
Technical field
The utility model belongs to transformer oil chromatographic on-line monitoring technique field, relates in particular to a kind of removable monitoring equipment of transformer.
Background technology
Power transformer is a visual plant in electric power system, its safe operation situation has directly determined the safety operation level of whole electric system, in transformer online monitoring technical research, transformer oil chromatographic on-line monitoring is to be subject to one of transformer online monitoring method that domestic power department is welcome, on-the-spot utilization product quantity is maximum at present.By kind, content and the variation tendency of monitoring oil dissolved gas, the latency fault that just can analyze the inner existence of judgment device also can be grasped the development of fault at any time, realizes the repair based on condition of component of transformer.
The degassed mode kind of the transformer oil chromatographic on-line monitoring product in market mainly contains film osmosis, vacuum outgas method, dynamic head space method now, but separate unit oil chromatography equipment is single degassed mode, and every kind of degassed mode has pros and cons, if these three kinds of degassed modes comprehensively can be gone in a transformer oil chromatographic on-line monitoring equipment, the situation of judgement Gases Dissolved in Transformer Oil that just can be comprehensive, but transformer oil chromatographic on-line monitoring is arranged near but transformer oil can not be done timely to off-line testing transformer field contrast.
Utility model content
For above-mentioned technical matters, the utility model provides a kind of the transformer oil chromatographic on-line monitoring of multiple degassed mode and off-line analysis is integrated into the removable monitoring equipment on car.
For solving the problems of the technologies described above, the technical scheme that the removable monitoring equipment of the utility model adopts is, a kind of removable monitoring equipment comprises film infiltration degassing sampling device, vacuum outgas sampling device, Dynamic Headspace device, chromatographic analysis device, gas and oil separating plant, vacuum oil circulating device and off-line chromatograph device, and the moveable platform of installing said apparatus, the isolated gas of described gas and oil separating plant enters respectively film infiltration degassing sampling device, vacuum outgas sampling device, Dynamic Headspace device; Isolated vacuum oil enters vacuum oil circulating device.
Receiving after monitoring task, removable the utility model monitoring equipment is moved to the transformer side that needs monitoring, the oil pipe of getting of gas and oil separating plant is received on oil pumping valve for transformer, open three kinds of degassing equipments and get separately oil, analyze, and can carry out by off-line chromatograph the analysis of oil sample, gas sample carries out stratographic analysis through the chromatographic column of different degassers, because the time of three kinds of degassed modes is different, so the time of stratographic analysis can stagger, so just can record result after three kinds of stratographic analyses, three kinds of degassed modes and the chromatographic result of off-line are contrasted and can better carry out transformer fault diagnosis.
Brief description of the drawings
Fig. 1 is the removable monitoring equipment structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is made and being further illustrated.
As shown in the figure, the removable monitoring equipment of the utility model comprises film infiltration degassing sampling device 4, vacuum outgas sampling device 6, Dynamic Headspace device 7, chromatographic analysis device 3, gas and oil separating plant 2, vacuum oil circulating device 8 and off-line chromatograph device 5, and the moveable platform of installing said apparatus, the isolated gas of described gas and oil separating plant enters respectively film infiltration degassing sampling device, vacuum outgas sampling device, Dynamic Headspace device; Isolated vacuum oil enters vacuum oil circulating device.
As preferably, described moveable platform is vehicular platform.
Receiving after monitoring task, the car that is loaded with the removable monitoring equipment of the utility model is driven to transformer 1 side that needs monitoring, the oil pipe of getting of gas and oil separating plant is received on oil pumping valve for transformer, open three kinds of degassing equipments and get separately oil and analyze, and can carry out by off-line chromatograph the analysis of oil sample.
One end of the oil sample introduction tube of gas and oil separating plant is connected with the oil-in of three kinds of degassing sampling devices, in three kinds of degassing sampling device top interface tandems gas-carrier pipeline before chromatographic analysis device chromatographic column, the signal output part of chromatographic analysis device divides with the signal input interface of chromatographic data chromatographic data analytical equipment and is connected, chromatographic data analysis result can be deposited on computers and also can be connected with cable telephony system, and is electrically connected with remote signal transmitting and receiving device through modulator-demodular unit.Simultaneously can be artificial to transformer oil sample carry out the chromatographic analysis of off-line, can contrast with the data result of on-line monitoring like this.
The utility model, owing to being arranged in minicar, becomes a movably entirety, can put into operation in time to scene fast, and capture device fault, realizes robotization and the intellectuality of overall process, ensures equipment safety operation.
For the safe operation that ensures transformer need to be monitored Gases Dissolved in Transformer Oil, can not only can realize transformer oil chromatographic on-line monitoring and can also realize by vehicle-mounted way the off-line test of Gas in Oil of Transformer, oil gas analysis adopts that film infiltration is degassed, vacuum outgas, the dynamic degassed mode that combines Synchronization Analysis of head space, and analysis by off-line device can be to omnibearing comprehensive judgement and the analysis of Gas in Oil of Transformer, thereby the diagnosis of transformer being carried out to fault is to safeguard reliable basis is provided transformer.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; it should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
