I.Overview
SF6 gas recovery and purification charging and discharging device is used for the manufacturing plant of SF6 gas insulation electrical equipment. In the departments of use, operation and scientific research, various electrical equipment is vacuumized, SF6 gas is filled into the electrical equipment, and SF6 gas is recovered from the electrical appliances in use or test, and purified, compressed and stored to storage tank at the same time.
The recycling device is suitable for SF6 electrical equipment and GIS combined electrical equipment.
According to DL/T662-1999 "Sulfur Hexafluoride Inflator and Recovery Device",the device is composed of recycling system, gas charging system, vacuum pumping system, purification system and gas storage system, with the following main functions:
1. Measure the vacuum and vacuum degree of the device and electrical equipment;
2. Recycle the gas in the electrical equipment;
3. Dry and purify SF6 gas recovered and refilled;
4. Inflate SF6 electric appliance;
5. Compressed storage and bottle filling of SF6 gas in electrical appliances.
II.The Main Components and Advantages of The Recovery Unit
(1) advanced design, complete functions, reasonable structure, simple and clear operation.
(2) compression system: SF6 sealed compressor, no leakage.
(3) double-stage rotary vane vacuum pump is adopted in the vacuum pumping system, which is equipped with an automatic oil return prevention device.
(4) the purification system adopts the principle filter of CKD company in Japan, and the filter adopts electric heating and high-efficiency adsorbent inside, so the purification effect is more significant (there is no need to change the adsorbent frequently).
(5) automatic confirmation of three-phase power supply and automatic protection of phase break in the electrical system of the device.
(6) the device control system adopts SF6 special valve with the latest technology
(7) the storage system shall be equipped with 50KG liquid storage tank according to user requirements. And can directly fill gas cylinders.
(8) the equipment is mobile.
III.Main Technical Performance Index
(1) type: mobile type, refrigeration type
(2) operating principle
A. Use compressor pressure -- refrigerate and liquefy SF6 gas.
B. Air recovery and recharge assisted by the dryer.
