Intellectual sulfur hexafluoride electric equipment air charging device of the present utility model, can inflate accurately automatically, accurately in various occasion.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the intellectual sulfur hexafluoride electric equipment air charging device of the utility model.
Embodiment
Below by embodiment, intellectual sulfur hexafluoride electric equipment air charging device of the present utility model is further described.See Fig. 1, inflator of the present utility model comprises many logical seat 1, at least one pressure transducer 2, temperature transducer 3, valve 4,5,6,14, exhaust gear 7, solenoid valve 8, computer data processing system 9.Computer data processing system 9 mainly comprises operation keyboard 91, processor of single chip computer 92 and a display screen 93.
Exhaust gear 7 in the intellectual sulfur hexafluoride electric equipment air charging device of the utility model, it mainly comprises adjustment cylinder, piston 71, adjustable lever, handwheel 72, valve 6.Exhaust gear 7 is sealed connected together mutually with many logical seats 1.Pressure transducer 2 and temperature transducer 3 also seal and are arranged on many logical seats 1.Many logical seats 1 are also connected with valve 5, and valve 5 is connected with solenoid valve 8, and solenoid valve 8 is circumscribed with tracheae 10, and tracheae 10 is connected on the reduction valve of sulfur hexafluoride gas cylinder.Many logical seats 1 are also connected with valve 4, and valve 4 is circumscribed with tracheae 11, and tracheae 11 is connected on the gas supplementing opening of sulfur hexafluoride electrical equipment 13.
When using at the scene, one end sulfur hexafluoride gas being connected tracheae 11 is connected with on the gas supplementing opening of sulfur hexafluoride electrical equipment 13, and the other end that sulfur hexafluoride gas connects tracheae 11 is connected with the equipment connection port outside the valve 4 on inflator.One end sulfur hexafluoride gas being connected tracheae 10 is connected with the reduction valve of sulfur hexafluoride gas cylinder 12, and the other end that sulfur hexafluoride gas connects tracheae 10 is connected with the gas cylinder connection mouth outside the solenoid valve 8 on inflator.After connecting, just start inflation.Its operation key step is as follows:
1. connect power source by inflator, if use AC220V power work, connect external power supply, power-on switch; If use self-contained battery work, direct power-on switch, preheating 5 minutes.
2. confirm that valve 4, valve 5, valve 6 are closed, valve 14 opens, by operation exhaust gear 7, adjusting handle 72, makes piston 71 move outward, the air venting of inflator pipeline in cylinder, then throttle down 14, Open valve 6, then shifts the end piston 71 onto toward in.Then throttle down 6, Open valve 14, then adjusting handle 72, make piston 71 move outward, the air venting of inflator pipeline in cylinder, then throttle down 14.Circulation like this, falls the air venting of inflator pipeline.
3. the charge density value (P20 value) of setting required for electrical equipment, Open valve 4 and valve 5, the automatic inflating button on operation inflator, automatic opens solenoid valve 8, starts inflation.And the computer data processing system 9 on inflator is in time according to the temperature value T on the temperature transducer 3 during inflation, the pressure-temperature characteristic relation of the pressure value P on pressure transducer 2 and sulfur hexafluoride gas carries out data processing, obtain corresponding density value (P20 DEG C of force value), when this density value (P20 DEG C of force value) equals to set the charge density value (P20 value) required for electrical equipment, the computer data processing system 9 meeting Self-shut electromagnetic valve 8 of inflator, automatic realization is inflated to the charge density value required by electrical equipment, realize automatic to sulfur hexafluoride electrical equipment, accurate inflation.
4. inflation after hours, throttle down 4 and valve 5, and it is just passable that disengagement connects tracheae 10 and 11.
5. turn off inflator power switch, restore.
The utility model is owing to have employed pressure, temperature intelligent collection, and intelligent conversion becomes density value, adopt solenoid valve automatically control, achieve to sulfur hexafluoride electrical equipment automatic, accurately inflate.Overcome and adopt general purpose pressure gauge reading at present, estimate its inflation pressure value and arrived specified value, then manually close charging valve, there is inflation and forbidden or inflate too much or inadequate problem.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, and all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
