With the rapid development of the power industry and the increasing investment in equipment, especially SF6 electrical equipment, the requirements for the installation, commissioning, maintenance and repair of SF6 electrical equipment are becoming higher and higher. In order to meet the needs of the market, coupled with our company's years of experience in SF6 electrical equipment testing, inspection and related professional technology, and drawing on the most advanced SF6 electrical maintenance equipment technology from abroad, we have developed the YHCQ series vacuum filling device with independent intellectual property rights. This device is mainly used for vacuum filling and filling of SF6 circuit breakers, transformers, GIS and other gas chambers. This product can be customized according to the requirements of different customers.

1. The internationally advanced freezing liquefaction method design principle is adopted, which reduces the working pressure of the system and greatly improves the efficiency of the recycling process.

2. Using a column level gauge, SF6 liquid level indication is intuitive and accurate.

3. Equipped with a naturally occurring dry filter.

4. Capable of liquefying SF6 gas and injecting it into steel cylinders.

5. The flowchart is drawn on the operation panel, making it easy and clear to operate.

6. Adopting air cooling and mobile design, it can be used without water source.

1. Vacuum pump speed: 30 liters per second (108m ³/h)

2. The maximum vacuum degree of the device is less than 10Pa

3. The annual leakage rate of the device is less than 1%

4. Noise level less than 75dB

6. The pressure of the inflation system is less than 0.8Mpa

7. Environmental temperature: -10 ℃ -+40 ℃

8. Power supply: AC three-phase 50Hz, 380V
