Accompanying drawing explanation
Fig. 1 is the utility model apparatus structure schematic diagram;
Fig. 2 is the utility model remote monitoring schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, a kind of device of remote monitoring bushing shell for transformer sealing, comprises adapter 1, T-valve 2, SF
6gas Density Sensor 3, vacuum pump 4, SF
6gas cylinder 5, and PLC, industrial computer, GPRS module form signal transmission component.
The SF with T-valve 2 is installed at pouring orifice 8 place on bushing shell for transformer conservator 7
6gas Density Sensor 3, the outlet of T-valve 2 is communicated with pouring orifice 8 by adapter 1, and vacuum pump 4 is connected with an import of T-valve 2, is extracted out by the air in sleeve pipe, SF
6gas cylinder 5 is connected with another import of T-valve 2, in sleeve pipe, be filled with SF
6gas.Conveniently vacuumize and insufflation gas, vacuum pump 4, SF
6the pipeline that gas cylinder 5 is connected with T-valve 2 is provided with valve 6.
During installation, the air in sleeve pipe extracted out by vacuum pump 4, when the pressure in sleeve pipe vacuumizes close to stopping time vacuum (such as when the pressure in sleeve pipe reaches 200Pa), and then is filled with SF
6gas, enters sleeve pipe by pouring orifice 8, stops gas injection, two imports of good seal T-valve 2 when the gaseous tension in sleeve pipe reaches 0.05MPa.
SF
6gas-insulated is functional, has been widely used in the built-in electrical insulation of isolating switch at present, can meet the requirement of high-voltage operation, and its relative molecular weight is greater than air, is slightly soluble in transformer oil.
As shown in Figure 2, described SF
6signal transmissions is formed by PLC, industrial computer, GPRS module between Gas Density Sensor 3 and long-range PC.PLC is with analog quantity input and digital output mouth, and GPRS module sends data, long-range PC receiver gases measuring density data.
PLC self carries out A/D conversion, gas density in sleeve pipe is reacted on industrial computer and is transferred on long-range PC, to the SF of inside pipe casing
6gas density carries out Real-Time Monitoring.When bobbin seal is good, SF
6the density value of gas can not change; When bobbin seal is bad, not only SF
6gas can be revealed, and the moisture in air also can penetrate into inside pipe casing by bobbin seal weakness, now industrial computer and long-range PC shows SF
6the density of gas drops to outside normal range.Therefore, SF can be passed through
6the change of gas density value judges that whether the sealing of bushing shell for transformer is good.
In transformer actual motion, when bushing shell for transformer good seal, due to the influence of temperature change by Transformer, the insulating oil of inside pipe casing can expand with heat and contract with cold, thus causes SF
6gas density can change within the specific limits, therefore can preset a warning value.Work as SF
6when the density of gas drops to predetermined warning value, industrial computer and long-range PC automatic alarm, illustrate that bobbin seal goes wrong, and the test that should have a power failure, checks.
The utility model is convenient to inject SF in sleeve pipe
6gas, then by monitoring SF
6the change of gas density value judges bushing shell for transformer whether poor sealing, can by the Real-Time Monitoring to bobbin seal, to go forward side by side row relax in initial stage Timeliness coverage defect of making moist, inside pipe casing is avoided to insulate deteriorated further and cause power grid accident, guarantee electric power netting safe running, creatively utilize PLC, GPRS communication remote monitoring bushing shell for transformer sealing condition, solve a difficult problem for bobbin seal monitoring.
