Symbol description: 100-SF6 all insulation cabinet, 1-sealed case, 2-first air flue, 3-second air flue, 4-vacuum machine and SF6 injection pump connecting head, 5-air compressor connecting head, 6-the 3rd air flue, 7-first solenoid valve, 8-second solenoid valve, 9-the 3rd solenoid valve, 10-first pressure transducer, 11-second pressure transducer.
Embodiment
Charger of bleeding of the present invention is mainly used in vacuumizing of SF6 all insulation cabinet and fills in SF6 gas operation, and it can avoid SF6 gas tank to take out the gas tank caused because inner and outer air pressure is inconsistent in gas replenishment process being out of shape even explosion phenomenon.
See figures.1.and.2, charger entirety of bleeding of the present invention is a sealed case 1, and this sealed case 1 is full closed structure, and general metallic material is made.As shown in Figure 1, the inner chamber of sealed case 1 is enough large, and SF6 all insulation cabinet 100 entirety can put into sealed case 1.
The sidewall of sealed case 1 is provided with the first air flue 2 and the second air flue 3 extended in case case.First air flue 2 is positioned at one end of sealed case 1 for being connected with the SF6 gas tank of SF6 all insulation cabinet, and the one end be positioned at outside sealed case 1 is provided with vacuum machine and SF6 injection pump connecting head 4.One end that second air flue 3 is positioned at sealed case 1 directly communicates with the inner chamber of sealed case 1, and the one end be positioned at outside sealed case is provided with air compressor connecting head 5.Be provided with between first air flue 2 and the second air flue 3 across the 3rd air flue 6, first air flue 2 is provided with the first solenoid valve 7 near the position of vacuum machine and SF6 injection pump connecting head 4, second air flue 3 is provided with in the second solenoid valve the 8, three air flue 6 near the position of air compressor connecting head 5 and is provided with the 3rd solenoid valve 9.First air flue 2 and the second air flue 3 are respectively equipped with the first pressure transducer 10 and the second pressure transducer 11, two pressure transducers are all positioned at outside sealed case 1.As shown in Figure 2, the leftward position place that the first air flue 2 is connected with the 3rd air flue 6 is located at by first pressure transducer 10, first solenoid valve 7 is positioned at right side, and the leftward position place that the second air flue 3 is connected with the 3rd air flue 6 is located at by the second pressure transducer 11, and the second solenoid valve 8 is positioned at right side.During work, the first pressure transducer 10 and the second pressure transducer 11 can detect the air pressure size of corresponding position.
