  1. Detailed information

One, usage of equipment

NALH mobile SF6 gas recovery inflatable device is mainly used for SF6 electrical switch manufacturers, research institutes, test stations, railway and iron and steel smelting, power plants, transmission and transformation engineering companies, high voltage power transmission and distribution substation GIS SF6 Switching electrical appliances for vacuum, gas, recovery and purification SF6 gas and liquefied cans storage SF6 gas. Can also be used for SF6 switch electrical products in the installation, commissioning and maintenance of auxiliary equipment used to remove excessive moisture, oil, dust and other impurities, to enhance its insulation properties. SF6 gas recovery device works is used for the host to the equipment within the gas chamber SF6 gas out and compressed to the critical pressure, making it into liquid storage in the storage tank. When the switching chamber is needed, the gas in the storage tank is returned to the equipment room. Which also contains drying system, purification system to ensure recovery of SF6 gas in the water content, oil content and impurities to meet national standards. But also contains a vacuum system to ensure that equipment is not mixed into the air and impurities. Can also be used for other gas use.

Two, the device main performance standard

1, the vacuum rate

In initial pressure of 0.1 Mpa final pressure of less than 133 pa conditions, the vacuum rate of less than 10m3 / h, 5m3 / h.

2, inflatable rate

In initial pressure is less than 133pa final pressure of 0.8Mpa conditions, the inflation rate of less than 10m3 / h, 5m3 / h.

3, the recovery rate

In the initial pressure of 0.8Mpa final pressure less than 100pa conditions, the recovery rate of 2m3 / h.

4, purification SF6 gas purity (quality control): recovery of SF6 gas trace moisture (gas humidity) is less than 50PPMm / V (volume ratio), oil less than 10PPMm / G (weight ratio), dust particle size is less than 20μm.

5, purification SF6 gas temperature control:

The temperature of the refrigerating machine is set to 0C to 20C. The temperature of the storage tank is set to 100C and the heating temperature of the activated molecular sieve is set to 400C.

6, the device to maintain the vacuum: 133Pa pressure to maintain 24h, the vacuum rose less than 400Pa.

7, purification SF6 gas humidity control: When the gas source of sulfur hexafluoride gas humidity: 1000μL / L, after a recovery of the gas humidity should be less than: <80μL / L.

8, the maximum storage pressure: <4.0Mpa.

9, the average time between failures 1000h device.

10, cumulative trouble-free running time 5000h.
