Technical Parameters of SF6 Gas Vacuum Pumping and Filling Device
With the rapid development of the power industry, the investment in infrastructure construction and equipment, especially the continuous increase of SF6 electrical equipment, has led to higher requirements for the installation, commissioning, and maintenance of SF6 electrical equipment. The relevant departments have put forward higher quality and time requirements for vacuum pumping and refilling during the construction and maintenance of SF6 electrical equipment (especially GIS). To meet the needs of this development, our company, based on years of experience in SF6 gas electrical equipment testing, detection, and professional technical expertise, and through analysis of the latest and most advanced maintenance equipment abroad, has developed the SHHSZ2000 series SF6 gas vacuum pumping and refilling device, which not only meets the technical requirements of the latest foreign equipment but also satisfies the price requirements of domestic users.
SHHSZ2000 series SF6 gas vacuum pumping and filling device is mainly used in power supply companies, power transmission and transformation engineering companies, power plants, ultra-high voltage transmission and transformation substations, SF6 electrical switch manufacturing plants, and other departments, as auxiliary equipment for installation, commissioning, and maintenance of SF6 electrical products such as GCBP, GCBT, GIS, etc. Use this device to perform vacuum pumping and SF6 gas refilling operations on the above electrical products. At the same time, this device can also be used as equipment for vacuum pumping and gas refilling in other departments.
In addition to all the functions required for SF6 gas vacuum pumping and refilling, this device also has the following features:
n Electronic vacuum degree display;
n Equipped with various imported and domestic SF6 electrical equipment connection joints;
n Automatic vacuum pumping according to the time or vacuum degree set by the user;
n Multiple protection functions to effectively ensure the safe operation of the vacuum pump;
n Easy maintenance, the device uses components with excellent performance, no maintenance required for long-term use.
