The recovery and storage of SF6 gas recovery device refers to the recovery of SF6 gas in electrical equipment to the storage container of the device for storage, generally from the initial recovery pressure to the final recovery pressure of the device or the final recovery pressure identified.
After connecting the pipes of the SF6 gas recovery device, determine whether to vacuum the device or pipe.
Start the refrigeration compressor half to one hour in advance according to the ambient temperature and amount of recovered gas at that time, until the end of recovery.
SF6 gas recovery device At the initial stage of recovery, when the initial recovery pressure (M1) is high, turn on V6, half-turn on V2 and SF6 compressors and turn on V3.
SF6 gas recovery unit after startup should pay attention to observing SF6 compressor exhaust pressure gauge (M2), the pressure of the M2 indicated value should be less than 2.0 MPa, the compressor outlet contact pressure controller, if the allowable value of indicated value reached 2.0 MPa, pressure controller can automatically cut off the operation of the compressor, pressure drop and stabilized, restart the compressor. Therefore, when the exhaust pressure rises too fast, the size of the compressor inlet V2 valve can be properly adjusted to control.
SF6 gas recovery device during the recovery process, pay attention to observe the liquid level in the storage container through the mirror glass, and the highest liquid level should not exceed 2/3 of the mirror.
When the SF6 gas recovery device reaches the final recovery pressure or a predetermined value, the recovery work ends.
