The neutral wire of the three-phase 380V power supply is not necessary, but the ground wire in the power cord must be reliably grounded. The electrical system is equipped with a phase sequence protection device. The phase sequence of the three-phase power supply can be directly adjusted through a manual switch. The electrical system also has phase loss protection, which can effectively prevent the reverse operation of the vacuum pump and the phase loss operation of all main machines.
1. This machine can be used for vacuum pumping and vacuum measurement of the device itself, as well as electrical equipment and storage tanks.
2. This machine recovers gas from electrical equipment.
3. This machine dries and purifies the recovered and refilled SF6 gas.
4. This machine fills SF6 electrical equipment with gas.
5. This machine compresses and stores SF6 gas in liquid form.
(1) Advanced design, complete functions, reasonable structure, and simple and clear operation.
(2) Compression system: Uses a sealed compressor specially designed for SF6, with no leakage.
(3) Vacuum pumping system uses a rotary vane vacuum pump with an automatic oil return prevention device.
(4) Purification system adopts the filter principle from CKD Corporation of Japan. The filter uses electric heating and contains high-efficiency adsorbent, making the purification effect more significant (no frequent replacement of adsorbent required).
(5) The electrical system of the device automatically confirms the three-phase power supply and provides automatic protection against phase loss.
(6) The control system of the device uses technically advanced SF6-specific valves.
