Description

A combined SF6 quick inflation device

technical field

The utility model relates to an equipment device, in particular to a combined SF6 fast inflation device.

Background technique

1. The models and specifications of the air supply joints of the equipment are not uniform. Due to the large number of GIS equipment manufacturers, the joints of each manufacturer are not universal, and the equipment of the same manufacturer with different batches and voltage levels also has inconsistent models of the air supply joints

2. There are a large number of GIS air supply equipment piled up in the warehouse, and it takes time to choose the matching air supply connector, and there may be problems of taking the wrong one. At the same time, the traditional air supply method consumes more air supply pipelines and pressure reducing valves, which increases the cost of air supply equipment.

3. The existing air replenishment device cannot realize the fast and reliable locking function in case of air leakage. During the daily use of air supply equipment, it is inevitable to cause aging and damage to the pipeline. At the same time, the pressure reducing valve has a service life. In the traditional air supply mode, it is troublesome to replace the air supply pipeline and pressure reducing valve. Especially when there is a pipeline leakage problem during the gas supply process of the GIS equipment, since the equipment is not powered off, once it is not handled in time (many GIS equipment inflation joints are fixed by three screws with a diameter of 6mm), the air pressure of the equipment will decrease rapidly and the lock will be blocked. switch, causing hidden dangers to safe operation. At the same time, due to the lack of replacement parts, the site cannot be replaced immediately, and the defects cannot be eliminated immediately, resulting in an increase in the unstable operation time of the equipment and causing hidden dangers to the safe operation of the power grid.
