Description
Technical field
The utility model relates to a kind of transformer oil gas-detecting device.
Background technology
Along with the fast development of electric system, the application of transformer is very general.Transformer is most important electrical equipment in electric system, once break down in operation, will cause serious consequence to electric system.The composition of Gases Dissolved in Transformer Oil and content can reflect insulation ag(e)ing degree in transformer or fault type to a certain extent.
Existing transformer oil gas-detecting device comprises upper shell, lower house.Upper shell is provided with gas sensor, and lower house is provided with filter element and oil-in and oil-out.But this pick-up unit can not coutroi velocity and signal analysis, and cause that flow velocity is unstable, signal can not immediate analysis process, thus causes that accuracy of detection is low, inefficiency.
Utility model content
For the deficiency that prior art exists, technical problem to be solved in the utility model is, provides a kind of accuracy of detection high, quick, efficient transformer oil gas-detecting device.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of transformer oil gas-detecting device, and it comprises signal processing system and signal acquiring system, the signal processor that signal processing system comprises PC and is connected electrically; Oil pump, inlet valve and reverse flow valve that signal acquiring system comprises signal pickup assembly, transformer and is communicated with transformer, signal pickup assembly comprises upper shell, lower house, gas sensor is provided with above upper shell inner plenum, gas filtration parts and oil-in and oil-out is provided with in lower house, the inwall of filter element and lower house forms oil pocket, the air chamber of the cavity connects upper shell in filter element; Be outside equipped with flowrate control valve at oil-in, flowrate control valve one end is communicated with oil-in, and one end is connected with inlet valve, and flowrate control valve, gas sensor are all electrically connected with PC by signal processor, and flowrate control valve is electromagnetic flow control valve.
The beneficial effects of the utility model: pick-up unit of the present utility model is provided with the size that flowrate control valve controls flow, makes it to be in most suitable state, is convenient to optimum value be detected.Flowrate control valve, gas sensor are electrically connected with PC by signal processor simultaneously, control, thus reach accuracy of detection high, quick, efficient effect when accepting in fact.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
Fig. 1 is the using state figure of the utility model embodiment;
Fig. 2 is the system architecture diagram of the utility model embodiment.
Embodiment
As illustrated in fig. 1 and 2, a kind of transformer oil gas-detecting device, it comprises signal processing system I and signal acquiring system II, the signal processor that signal processing system comprises PC and is connected electrically; Oil pump 10, inlet valve 9 and reverse flow valve 11 that signal acquiring system comprises signal pickup assembly, transformer 12 and is communicated with transformer 12, signal pickup assembly comprises upper shell 2, lower house 5, gas sensor 1 is provided with above upper shell inner plenum 3, gas filtration parts 4 and oil-in 6 and oil-out 7 is provided with in lower house 5, filter element 4 forms oil pocket, the air chamber 3 of the cavity connects upper shell 2 in filter element 4 with the inwall of lower house 5; Flowrate control valve 8 is outside equipped with at oil-in 6, flowrate control valve 8 one end is communicated with oil-in 6, one end is connected with inlet valve 9, and flowrate control valve 8, gas sensor 1 are all electrically connected with PC by signal processor, and flowrate control valve 8 is electromagnetic flow control valve.
During detection, first open inlet valve 9 and reverse flow valve 11, and start oil pump 10, form circulating oil path with transformer 12.In oil, gas enters air chamber 3 through filter element 4, by gas sensor 1 collection signal, is sent to PC and carries out analysis detection gas signal, thus reach rapid, testing goal accurately and efficiently through signal processor.
As shown in Figure 2, the gas signal that signal acquiring system collects is sent to PC through signal processor and carries out analysis detection.
Claims (2)
