Description
Technical field
The utility model relates to the calibration technology field of instrument and meter, is specially SF6 density monitor verification servicing unit.
Background technology
At present, with traditional SF6 density relay checking instrument, at work, main existence is because of connection and dismantle the problem that circuit constantly interrupts verifying work.Before verification, need to do a large amount of preliminary works such as connecting line circuit, gas circuit and signalling contact connection, after verification completes, after wiring need to being disassembled completely from SF6 density monitor, reconnect next SF6 density monitor to be measured again and just can proceed verification, this needs verification personnel constantly to interrupt verifying work, spends the more time for wiring preliminary work and dismantlement work, be unfavorable for verifying work continue carry out, reduced work efficiency.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of SF6 density monitor verification servicing unit, and concrete technical scheme is as follows:
SF6 density monitor verification servicing unit, comprise two above identical test branch roads of structure, the air intake opening of each test branch road connects the gas outlet of supercharge pump by inlet manifold road, the exhausr port of each test branch road is connected to exhaust main road, and exhaust main road is connected to the air intake opening of supercharge pump more successively by filtrator, air reservoir, separation vessel; The air intake opening of described test branch road is one end of direct-acting valve, and the other end of direct-acting valve connects the air intake opening of gas control valve; Gas control valve is also provided with test port and exhausr port: test port is connected tested SF6 density monitor by pressure transducer, and exhausr port is the exhausr port of test branch road.
Described test branch road has four.
The utility model can realize that many test branch roads are parallel, the order effect of verification one by one.In the time of SF6 density monitor in test branch road of verification, complete wiring preliminary work and the dismantlement work of other test branch roads, guaranteed verifying work continue carry out, improved work efficiency.
Accompanying drawing explanation
Fig. 1 is SF6 density monitor verification servicing unit gas circuit connection diagram.
In figure: 1-supercharge pump; 2-inlet manifold road; 3-direct-acting valve; 4-air intake opening; 5-gas control valve; 6-test port; The tested SF6 density monitor of 7-; 8-pressure transducer; 9-exhausr port; 10-exhaust main road; 11-filtrator; 12-air reservoir; 13-separation vessel; 14-signals collecting line.
Embodiment
By reference to the accompanying drawings, SF6 density monitor verification servicing unit, comprise two above identical test branch roads of structure, the air intake opening of each test branch road connects the gas outlet of supercharge pump 1 by inlet manifold road 2, the exhausr port of each test branch road is connected to exhaust main road 10, and exhaust main road 10 is connected to the air intake opening of supercharge pump 1 more successively by filtrator 11, air reservoir 12, separation vessel 13; The air intake opening of described test branch road is one end of direct-acting valve 3, and the other end of direct-acting valve 3 connects the air intake opening 4 of gas control valve 5; Gas control valve 5 is also provided with test port 6 and exhausr port 9: test port 6 is connected tested SF6 density monitor 7 by pressure transducer 8, and exhausr port 9 is the exhausr port of test branch road.Described test branch road has four.
During verification, four tested SF6 density monitors are accessed respectively in four test branch roads.First start the verifying work of tested SF6 density monitor in article one test branch road: the direct-acting valve 3 of opening article one test branch road, gas is discharged from supercharge pump 1, by inlet manifold road 2, through air intake opening 4, test port 6, the tested SF6 density monitor 7 of pressure transducer 8 arrival of direct-acting valve 3, gas control valve 5; When gas reaches preset value, tested SF6 density monitor 7 contact point signals gather and are sent to SF6 density relay checking instrument by signals collecting line 14; After being completed, close direct-acting valve 3, gas is discharged from tested SF6 density monitor 7, test port 6, exhausr port 9 through pressure transducer 8, gas control valve 5, by exhaust main road 10, pass through successively filter 11, air reservoir 12 and separation vessel 13 again, finally arrive supercharge pump 1, article one test branch road verifying work is complete.
Then start the verifying work of tested SF6 density monitor 7 in second test branch road, meanwhile, the wiring of the complete SF6 density monitor of verification in dismounting article one test branch road, and change an another SF6 density monitor to be measured.So repeat the 3rd, the 4th test branch road, after treating the 4th the SF6 density monitor verification in test branch road, in dismounting wiring, starts the verifying work of tested SF6 density monitor 7 in article one test branch road.So circulation, makes verifying work continue to carry out.
