Abstract
The utility model relates to an on-line sulfur hexafluoride charging connector, which is mainly used for high voltage combined electric appliance on-line sulfur hexafluoride charging facilities. The connector comprises a charging port and a pressure reducing valve and is characterized in that an inverted valve is arranged between the charging port and the pressure reducing valve. The on-line sulfur hexafluoride gas charging connector provided by the utility model has the beneficial effect that leakage of sulfur hexafluoride gas is prevented through the inverted valve, thus the phenomenon that suffocation of field operation personnel and causes damage to the personnel are caused by leakage in the field gas charging operation process is avoided, and the safety coefficient of an electric system is improved.
Description
Technical field
The utility model is mainly used in the online sulphur hexafluoride inflation of high pressure combined electrical apparatus facility, is specifically related to the online gas-charging connection of a kind of sulphur hexafluoride.
Background technique
Fig. 1 is the structural drawing of the existing online gas-charging connection of sulphur hexafluoride.It is made up of charging air inlet and reduction valve.It is inflated in the operation process at the scene, and leakage phenomenon often takes place, and causes the site operation personnel to suffocate when serious, and the personnel that cause injure.
Summary of the invention
For fear of execute-in-place generation charge leaks phenomenon, the utility model provides a kind of sulphur hexafluoride online gas-charging connection.
The utility model comprises charging air inlet and reduction valve, it is characterized in that being provided with check valve between charging air inlet and the reduction valve.
The utility model stops the leakage of sulfur hexafluoride gas through check valve, can avoid inflating at the scene in the operation process, takes place to leak to cause the site operation personnel to suffocate, and the phenomenon that the personnel that cause injure has improved the safety coefficient of electric power system.
