North Branch Electric Power Co., Ltd. Wuhan backfilling gas SF6 gas purification device manufacturers BKH ..

I. Overview Wuhan Electric North Branch Electric Co. BKHC-40Y-type SF6 gas recovery charge and discharge means for purification SF6 gas insulated electrical equipment factory, using the run scientific research departments, a variety of electrical equipment was evacuated to Appliances filled with SF6 gas and SF6 gas recovered from the use or testing of appliances, but for purification to compress storage tank. Recovery applies SF6 GIS combination of electrical switches and other electrical appliances. The device according to DL / T662-1999 "sulfur hexafluoride inflatable and recovery" standard, means the recovery system, inflation system, vacuum system, purification system, gas storage system components, has the following main features: 1, this means machine and electrical equipment measuring vacuum and vacuum pump; (2) the gas for electrical equipment for recycling; 3, for the recovery and back-filled with the SF6 gas drying, purification; 4, SF6 electrical inflate; 5, appliances SF6 gas is compressed and stored. Equipment in 1992 (energy technology Kam 9203028 #) through the Ministry of experts, in 1995 (62 # 95 Kam electrical regulations) through the Ministry of experts, 1993 Jiangsu Province Torch Program Product (10624G0029 #), 1993 Jiangsu High-tech products (Ke Ji 94051 #). Second, the work flow of 1, recovered SF6 gas SF6 when withdrawn from a gas chamber, the gas will flow through the purifying filter automatically through SF6 compressed by the compressor cooling purification, to a certain high pressure in liquid form into SF6 storage reservoir cans. 2, SF6 switch evacuated using a vacuum pump to electrical switches in addition to the gas can be pumped, pump outlet to the atmosphere. 3, inflatable purified and dried SF6 filling from tank has been evacuated back to the gas chamber until the gas chamber pressure reaches the set pressure of work. Above work in two steps: 1, with SF6 tank pressure SF6 gas vaporized flow switch, until a predetermined inflation pressure. 2, when the SF6 tank pressure switch with SF6 pressure balance, then using compressor pressurized inflation, until a predetermined inflation pressure. Third, the main components and the advantages (1) design advanced, full-featured, well-structured. (2) compression system: SF6 special fluoride-resistant closure pressure compressor, no leakage. (3) vacuum system uses two-stage rotary vane vacuum pump, provided in the system to automatically prevent the return of oil installations. (4) cleaning system used by the US company principle EMERSON filter, the filter using electric heating and built efficient adsorbents, purification purifying effect is more pronounced (without frequent replacement of the adsorbent). (5) means a three-phase electrical power system automatically confirmed, phase automatic protection. (6) The device control system using the latest technology in Germany DILO SF6 special valves, two vacuum pressure does not leak. (7) storage systems configured according to user requirements 80-200L storage tank. (8) the use of mobile devices. Fourth, the main technical performance indicators (1) Type: mobile, (2) Principle of condensing pressure a, using a high-pressure compressor - SF6 gas is condensed and liquefied. Gas liquid purification. b, drier auxiliary gas recovery and backfilling. c, through inflated cushion filled gasification (heated). (3) Operating temperature: -10 ℃ --- + 40 ℃ (4) Main performance and technical parameters 1, means the ultimate vacuum <10Pa 2, means evacuation rate 40-60m3 / h (vacuum pump ultimate vacuum 0.06Pa ) 3, the inflatable device early pressure <133 Pa (user requirements custom) 4. final pressure inflatable device ≤0.8M Pa 5, inflate the device rate> early 10m3 / h 6, means the pressure to ≤0.8M Pa 7, means for recovering the final pressure <-0.053MPa 8, device recovery compressor speed 12m3 / h 9, means annual leakage rate of <1% 10, means the maximum design pressure of the tank 4.8M Pa 11, tank volume 80-200L 12, dimensions of about 1500mm × 1100mm × 1600mm 13, for storage: liquid, gaseous 14 15 SPL noise ≤75dB dry filter regeneration mode: vacuum regeneration heat activated for 16, Power: AC Three-phase 380V ± 10%, 50HZ 17, means the total power <8KW 18, device Weight: 550-700 kg 19, purification: micro water 60PPm, oil 5PPm, dust ≤1 micron five main components and functions of the apparatus main functional parts have compressors, vacuum pumps, dry filter regenerator , heaters, purifiers, filters, piping, valves, instrumentation control, electrical control and structure, framework panel, go round and storage tanks. 6, the main part of configuration parameters 1, SF6 compressor: Italy DORIN a: Theoretical Displacement: 12m3 / hb: Maximum discharge pressure: 3.8Mpa c: Minimum suction pressure: 50Kpa d: maximal inspiratory pressure: 0.8Mpa e : Power: 3KW 2, vacuum system with dual-stage rotary vane vacuum pump Germany owned a: vacuum pump with air-cooled long-term operation b: evacuation rate 40-60m3 / h - c: ultimate vacuum 0.6pa d: Power 1.5 -2.2KW 3, Cooling System: Host 4600 Kcal / h, R22,1.5KW, 220 / 380V50HZ (optional) 4, filtration / purification system: imported EMERSON D48H filters and other, including oil and gas filtering / particulate filter / micro water filter / 5, SF6 valve: Ball SF6 special 3-365R01 / safety valve 6, pressure gauges, vacuum table: Y-100 liquid-filled 1413, Shanghai thermocouple vacuum gauge
