Description
Technical field
The utility model relates to a kind of on-line monitoring system, particularly a kind of without the non-maintaining chromatography online monitoring system for transformer oil of gas cylinder.
Background technology
In the time carrying out the monitoring of transformer duty, that mode by the cold oil of transformer being carried out to stratographic analysis is carried out, concrete derives by being the cold oil circulating in transformer, enter chromatographic column through this part gas of gas-oil separation relief, various gases in this part mixed gas are expelled in order gas sensor and detect one by one after chromatographic column, judge the duty of transformer according to testing result.In traditional monitoring system in order to allow the gas sample separating from transformer oil be transported in chromatographic column, need to use high pure air or high pure nitrogen as carrier gas, so just need to use 1 to 2 steel cylinder for storing high-purity air or nitrogen, but along with the continuous consumption of system monitoring work, steel cylinder need to regularly be changed, for scene operation brings very large inconvenience, and improve the holistic cost of system.Therefore need now a kind of novel transformer oil chromatography on-line monitoring system that can address the above problem.
Summary of the invention
The utility model is in order to solve the existing above-mentioned deficiency of prior art, propose a kind of simple in structure, design ingenious, rationally distributed, do not need to regularly replace steel cylinder without the non-maintaining chromatography online monitoring system for transformer oil of gas cylinder.
Technical solution of the present utility model is: a kind of without the non-maintaining chromatography online monitoring system for transformer oil of gas cylinder, it is characterized in that: described system comprises air pump 1, the inlet end of air pump 1 is connected with air filtering core 2, the outlet side of air pump 1 is communicated with gas-holder 4 by retaining valve 3, on gas-holder 4, be provided with the first exhaust emission tube road 5 by solenoid control, gas-holder 4 is by being connected with polymeric membrane ingress filter device 7 with air particles contaminant filter 6 successively with the pipeline of solenoid valve, on polymeric membrane ingress filter device 7, be provided with the second exhaust emission tube road 8 by solenoid control, polymeric membrane ingress filter device 7 is also communicated with the first intake line 12 of six three-way electromagnetic valves 11 by pressure regulator valve 9 and flow stabilizing valve 10, the first output pipe 13 of six three-way electromagnetic valves 11 is connected with chromatographic column 14, the second intake line 15 of six three-way electromagnetic valves 11 is communicated with gas-oil separation unit 16, and on six three-way electromagnetic valves 11, be also provided with the second output pipe 17.
Compared with the existing technology, tool has the following advantages the utility model:
This kind of version without the non-maintaining chromatography online monitoring system for transformer oil of gas cylinder, it is simple in structure, designs ingenious.The carrier gas source of traditional chromatography online monitoring system for transformer oil is the steel cylinder that is filled with high pure air or high pure nitrogen, therefore need regularly to change, not only increase labor capacity, also improved the holistic cost of system simultaneously, for this problem, the utility model is designed a kind of alternative steel cylinder provides the system of pure air, it can be real-time generation high purity air, and transport gas sample as carrier gas, the appearance of this structure, the extra cost of having avoided frequent replacing steel cylinder to produce, really accomplishes non-maintaining.And its manufacture craft is simple, cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market outlook are very wide.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings embodiment of the present utility model.As shown in Figure 1: a kind of without the non-maintaining chromatography online monitoring system for transformer oil of gas cylinder, this system comprises air pump 1, the inlet end of this air pump 1 is connected with air filtering core 2, the outlet side of air pump 1 is connected with gas-holder 4 by retaining valve 3, on gas-holder 4, be also provided with the first exhaust emission tube road 5 by solenoid control, gas-holder 4 is also by being connected with polymeric membrane ingress filter device 7 with air particles contaminant filter 6 successively with the pipeline of solenoid valve, and be also communicated with the first intake line 12 of six three-way electromagnetic valves 11 by pressure regulator valve 9 and flow stabilizing valve 10 at polymeric membrane ingress filter device 7, the first output pipe 13 of six three-way electromagnetic valves 11 is connected with chromatographic column 14, the second intake line 15 of six three-way electromagnetic valves 11 is connected with gas-oil separation unit 16, on six three-way electromagnetic valves 11, be also provided with the second output pipe 17.
The course of work without the non-maintaining chromatography online monitoring system for transformer oil of gas cylinder of the utility model embodiment is as follows: first the transformer oil in transformer enters in gas-oil separation unit 16 by in-line, the gas being mingled with in transformer oil is separated (this part gas is the gas sample that needs detect) in gas-oil separation unit 16, and input in six three-way electromagnetic valves 11 by the second intake line 15, the transformer oil after degassed comes back in transformer, now the second intake line 15 and the second output pipe 17 are interconnected, the second output pipe 17 is exhaust emission tube road, gas sample is discharged by the second output pipe 17, after discharging a period of time, close the solenoid valve on the second intake line 15 and the second output pipe 17, now in the quantity tube in six three-way electromagnetic valves 11, there is a certain amount of gas sample, then six three-way electromagnetic valves 11 rotate, allow an intake line 12 be connected with the first output pipe 13 by after quantity tube, the high pure air blowing in the first intake line 12 can promote quantitative gas sample and enter chromatographic column 14, various gases in gas sample are expelled in order gas sensor and detect one by one,
High pure air in the first intake line 12 obtains by following steps: air pump 1 starts, after tentatively being filtered by air filtering core 2, air is input in gas-holder 4, open on the first exhaust emission tube road 5 being connected with gas-holder 4 in the time starting most, to in gas-holder 4, not have after preliminary filtered air emptying, close the solenoid valve on the first exhaust emission tube road 5, then the air in gas-holder 4 carries out secondary filtration through air particles contaminant filter 6, remove (humid air that contains moisture content is discharged by the second exhaust emission tube road 8) after moisture content through polymeric membrane ingress filter device 7, after pressure regulator valve 9 and flow stabilizing valve 10, form pure, stable air, as carrier gas.
