SF6 Vacuum Pumping and Air Charging Device

create time:2017-12-01

   

 

Brief introduction 
    With the development of electric power industry in China, the requirement for installation, commissioning and maintenance of SF6 electrical equipment is higher and higher, so is to the quality and time for vacuum pumping and recharging air and filling back of SF6 electrical equipment (especially GIS) by relevant departments during construction and maintenance.To meet the needs of the development, the company has developed SF6 vacuum pumping products to meet the needs of domestic users by referring to the test, inspection and professional technology of foreign SF6 air and electrical equipment, with the products meeting the technical requirements of foreign advanced equipment.
  
Usages:
    SF6 vacuum pumping and recharging device is mainly applied to sectors such as power companies, power transmission and substation engineering companies, power plants, EHV transmission substations, SF6 electric switch factories and so on, as auxiliary equipment of SF6 electrical products such as GCBP, GCBT, GIS etc. in the installation, commissioning and maintenance. The device is used to vacuum and recharge SF6 air for the above electrical appliances, and at the same time, it can also be used to vacuum and recharge air for other sectors.
  
    The device is used to vacuum the SF6 breaker chamber of above electrical equipment, which can effectively reduce the humidity (water vapour content) inside the SF6 switching equipment, remove the trace moisture in the device, and also make qualitative leak detection for the equipment.
  
Product characteristics
  
1. Fast in pumping air and vacuuming GIS equipment, qualitative in leak detection;
  
2. Pressure regulating and air charging;
  
3. Strong structure, light weight, small volume, easy to move with universal wheel chassis.
  
4. Equipped with each type of vacuum meters, displayed in vacuum degree (the vacuum meter can be configured according to the requirements of users).
  
5. Equipped with all kinds of imported and domestic connection joints for SF6 electrical equipment (optional);
  
6. Automatic in vacuum pumping according to the time set by users or the degree of vacuum (optional);
  
7. With multiple protection functions to effectively ensure the safe operation of vacuum pump;
  
8. Simple operation, convenient maintenance, with the device using excellent parts, long time operation, free maintenance.
