Using three-phase 380V power supply, the neutral line 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 avoid reverse operation of the vacuum pump and phase loss operation of all main machines.
1. This machine can perform vacuum pumping and vacuum degree measurement on the device itself, 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 appliances with gas.
5. This machine compresses and stores SF6 gas in liquid form from electrical appliances.
(1) Advanced design, complete functions, reasonable structure, and simple and clear operation.
(2) Compression system: uses a dedicated sealed compressor for SF6, leak-free.
(3) Vacuum pumping system uses a rotary vane vacuum pump with an automatic oil return prevention device.
(4) The purification system adopts a filter based on the principle of CKD Corporation of Japan. The filter uses electric heating and built-in high-efficiency adsorbent, making the purification effect more significant (no need for frequent replacement of adsorbent).
(5) The electrical system of the device automatically confirms the three-phase power supply and automatically protects against phase loss.
(6) The control system of the device adopts technically advanced SF6 special valves
