Abstract
The invention discloses a general type SF6-gas filling device. The general type SF6-gas filling device comprises a pressure reducer, a gas-filling pipeline, an emergent braking valve, an inserting-pulling type joint and a gas-filling-joint matched joint, wherein the pressure reducer comprises a gas-cylinder-side meter, a pipeline-side meter and a pressure reducing valve; a gas inlet of the pressure reducing valve is connected with a gas cylinder, and a gas filling hole of the pressure reducing valve is connected at one end of the gas-filling pipeline; the other end of the gas-filling pipeline is connected with the emergent braking valve; and the inserting-pulling type joint and the gas-filling-joint matched joint are arranged on the emergent braking valve. The general type SF6-gas filling device disclosed by the invention has the advantages that the condition that when an operator fills gas, equipment can not supply gas due to wrong taking of a gas-filling joint and toxic gas is leaked due to damage and leakage of the joint can be prevented, the safety of workers and the equipment is guaranteed, simultaneously the storage space can be saved, the gas-filling time can be saved, the rush-repairing efficiency can be improved and the cost can be saved.
Description
technical field:
The present invention relates to a kind of universal SF
6gas inflator.
background technique:
Along with the raising with technical equipment that develops rapidly of China's power industry, electric substation is all kinds of fills SF
6gas apparatus puts into operation in a large number, the SF that in electric substation, all kinds of charger fills
6gas, has very high insulating strength and arc extinguishing intensity, is used widely in electric power system.At present, electric substation is all kinds of fills SF
6gas apparatus gas-charging connection and pipeline respectively have a set of, are all not quite similar.Under high voltage arc action, SF
6gas can decompose, and produce toxic gas, often charger can exist SF
6leakage Gas, the situations such as pipeline is aging, poorly sealed; Staff needs supplementary SF at equipment
6during gas, may take pipeline and gas-charging connection by mistake, maybe will there is the joint of hidden danger to staff, above situation all can bring potential safety hazard to staff.
summary of the invention:
In order to overcome prior art Problems existing, the invention provides a kind of universal SF
6gas inflator, solves operating personnel when inflating, and prevents from taking by mistake gas-charging connection and causes equipment cannot make-up gas and the toxic gas leakage situation that causes due to joint uterine bleeding, ensure the safety of staff and equipment.
For solving the problems of the technologies described above, the present invention takes following technological scheme:
A kind of universal SF
6gas inflator, by decompressor, loading line, promptly prevent valve, plug type joint and gas-charging connection complementary connector and form, wherein decompressor comprises gas cylinder side meter, pipeline side meter and reduction valve, its reduction valve suction port is connected with gas cylinder, and reduction valve inflation inlet is connected to one end of loading line; The other end of loading line with promptly prevents valve and is connected, plug type joint and gas-charging connection complementary connector are installed on promptly on prevention valve.
Plug type joint is the plug joint corresponding with treating charger body gas-charging connection, can change.
Decompressor is for controlling gas flow rate in gas replenishment process and flow, gas cylinder side meter display gas cylinder air pressure P1 (P1:0.1-5MPa), pipeline side meter display tube trackside gauge pressure P2(setting value is identical with treating charger rating value, and P2:0.1-1MPa).
Loading line connects gas cylinder and treats charger, provides SF
6gas flowing path, effectively intercepts SF
6gas and air, contact with moisture.
Urgent prevention valve is when loading line or when charger gas-charging connection occurs to leak or decompressor valve breaks down, can emergent stopping tonifying Qi process, ensures the person, device security.
Beneficial effect of the present invention is: (1) this universal SF
6gas inflator can realize any crewmember when not knowing well gas-charging connection and pipeline, can not take gas-charging connection by mistake; (2) in gas replenishment process, use this device can greatly reduce the generation of loading line uterine bleeding and gas leakage accidents, ensure safety and the device security of operating personnel; (3) this universal SF is promoted the use of
6gas inflator, can save parking space, saves inflationtime, improves first-aid repair efficiency, cost-saving.

embodiment:
Below in conjunction with drawings and the specific embodiments, technological scheme of the present invention is described in detail.
As shown in Fig. 1 ~ 3, a kind of universal SF
6gas inflator, be made up of decompressor 1, loading line 2, urgent valve 3, plug type joint 4 and gas-charging connection 5 complementary connector prevented, wherein decompressor 1 comprises gas cylinder side meter 6, pipeline side meter 7 and reduction valve 8, its reduction valve suction port 9 is connected with gas cylinder 10, and reduction valve inflation inlet 11 is connected to one end of loading line 2; The other end of loading line 2 with promptly prevents valve 3 and is connected, plug type joint 4 and gas-charging connection 5 complementary connector are installed on urgent prevention valve 3; Plug type joint 4 is the plug joint corresponding with treating charger body gas-charging connection, replaceable.
Before inflation, first the plug joint 4 corresponding with treating charger body gas-charging connection is selected, this plug joint 4 is combined with gas-charging connection 5, then gas-charging connection 5 is connected with the loading line combined, namely be followed successively by reduction valve inflation inlet 11-loading line 2-urgent valve 3-gas-charging connection 5 of preventing to form complete inflation gas circuit, finally gas cylinder 10 is docked with reduction valve suction port 9; By plug joint 4 and the supporting good joint of gas-charging connection 5 with treat that charger body gas-charging connection docks, open gas cylinder valve successively and reduction valve valve can carry out tonifying Qi to equipment.
This universal SF
6the operation instruction of gas inflator:
(1) visual examination being carried out to loading line, checking that pipeline flawless, seal ring are good, joint is clean without falling ash;
(2) by universal SF
6gas inflator is connected to gas cylinder (gas cylinder air pressure meets the requirements), first turns on gas cylinder valve slow releasing SF6 gas 1 minute, to rinse out air in pipeline, impurity and moisture;
(3) according to treating that reduction valve pipeline side meter indicating value is slowly adjusted to this rating value by charger nominal pressure value;
(4) under ensureing that pipeline connects reliable situation, slowly turn on gas cylinder valve, equipment is inflated;
