Portable SF6 Gas Recovery Device
Portable SF6 Gas Recovery Device is mainly used for vacuuming, vacuum measurement, and other operations during the installation, operation, and maintenance of porcelain-clad SF6 circuit breakers, transformers, and other SF6 electrical equipment. It is a compact SF6 gas charging and evacuation device, with the entire charging and vacuuming system mounted on a very sturdy metal cart frame, allowing it to move smoothly even on gravel roads. The entire SF6 gas charging and evacuation device includes: vacuum pump, pointer vacuum gauge, regulating valve, gas transmission hose, and necessary valves and instrument control components for maintaining SF6 circuit breakers.
Product Features:
1. Portable SF6 Gas Recovery Device can evacuate SF6 electrical equipment and measure vacuum level.
2. This device can charge SF6 gas into SF6 electrical equipment.
3. This device can recover gas from SF6 electrical equipment.
4. This device can purify the recovered SF6 gas.
5. This device stores SF6 gas.
6. This device is developed according to the standard DL/T 662-1999 "Technical Conditions for SF6 Gas Recovery Device" of the Ministry of Electric Power, referencing products from world-renowned brands, and adopting the latest national technology. The device consists of a recovery system, charging system, vacuum system, purification system, and storage system, with the following main functions:
7. Measurement of vacuum and vacuum degree for the device itself, electrical equipment, and storage tanks.
8. Recovery of gas from electrical equipment.
9. Drying and purification of recovered and recharged SF6 gas.
10. Charging SF6 gas into SF6 electrical equipment.
11. Compressing and storing SF6 gas in liquid form from electrical equipment.
12. Adopting the system principles and technology of DILO Company in Germany, with advanced design, complete functions, reasonable structure, and simple and clear operation.
13. The compression system uses a semi-hermetic compressor with imported compression technology, which has stable performance and a significantly longer service life than previous models.
14. The vacuum system uses a two-stage rotary vane vacuum pump with fast vacuum speed, and the system is equipped with an oil return prevention device.
15. The purification system adopts the filter of Neil Company in the United States. The filter uses a two-stage built-in electric heating and built-in high-efficiency adsorbent, resulting in more significant purification effects (no frequent replacement of adsorbent required).
16. The electrical system of the device automatically confirms and adjusts the three-phase power supply.
17. The control system of the device uses the latest SF6-specific instruments and valves, which are more reliable than similar products with ball valves.
18. The storage system is configured with a liquid storage tank according to user requirements.
19. The equipment adopts an air-cooled mobile type and can be used without an external water source.
