With the rapid development of the power industry and the increasing investment in infrastructure and equipment, especially SF6 electrical equipment, the requirements for installation, commissioning, maintenance and repair of SF6 electrical equipment are becoming higher and higher. Relevant departments have put forward higher quality and time requirements for vacuum pumping and gas replenishment during the construction and maintenance of SF6 electrical equipment (especially GIS).

The KDQC-33 SF6 vacuum pumping device is mainly used in various power supply companies, power transmission and transformation engineering companies, power plants, ultra-high voltage transmission and transformation power stations, SF6 electrical switch manufacturing plants and other departments, as an auxiliary equipment for the installation, commissioning, and maintenance of SF6 electrical products such as GCBP, GCBT, GIS, etc. This device can be used for vacuuming and refilling SF6 gas on the above-mentioned electrical products, and can also be used as equipment for vacuuming and refilling gas in other departments.

In addition to most of the functions required for SF6 gas vacuuming and recharging, this device also has the following characteristics:

2. McDonald's vacuum gauge display (other vacuum gauges can be configured according to user requirements);

3. Equipped with various imported and domestic SF6 electrical equipment connection joints (optional);

4. Automatically evacuate according to the user's set time or vacuum level (optional);

5. Multiple protection functions effectively ensure the safe operation of the vacuum pump;

6. Easy to maintain, the device uses high-performance components and does not require maintenance even after long-term use.
