Description
Technical field
The utility model relates to a kind of sampling system sampled transmission line of electricity transformer station SF6 equipment, sampling system used when particularly a kind of sulfur hexafluoride equipment that fills to transformer station carries out dynamic diagnosis.
Background technology
Along with developing rapidly of power industry, voltage levels fills sulfur hexafluoride number of devices constantly to be increased, and this equipment is after long-play, and potential safety hazard starts to occur.Due to the characteristic of sulfur hexafluoride decomposer, field instrument can not detect the content of all analytes, in addition also there is the problem that demarcation is difficult and stability is bad in field instrument, this just needs a safe and reliable acquisition system, filling sulfur hexafluoride gas in sulfur hexafluoride equipment in running when carrying out stratographic analysis without gathering go back to testing laboratory when any pollution, the content analyzing sulfur hexafluoride decomposer and the relation of filling between sulfur hexafluoride hidden trouble of equipment and accident, realize the dynamic diagnosis to filling sulfur hexafluoride equipment.Existing gas production bottle has gas washing and gas production two kinds of functions concurrently, there is gas washing not thoroughly and the problem of the on-the-spot bad operation control of gas production, in sampling process, the gas washed out in sampling bottle is directly discharged in air, because sulfur hexafluoride is greenhouse gases, its decomposition product is toxic and harmful, cause air pollution.
Summary of the invention
The utility model provides a kind of sampling system of transformer station SF6 equipment, the technical matters that the gas washing solving the existence of existing sampling operation does not thoroughly pollute air with the gas washed out.
The utility model solves above technical matters by the following technical programs:
A kind of sampling system of transformer station SF6 equipment, comprise vacuum pump, sampling bottle and Drexel bottle, sampling bottle is arranged in Drexel bottle, sampling bottle is that opening is arranged, the bottleneck of Drexel bottle is provided with bottle cap and plug, one end of vacuum-pumping tube is arranged on the bottle mouth position of Drexel bottle by bottle cap and plug, the other end of vacuum-pumping tube is together with the second port UNICOM of four way ball valve, one end of sample lines is arranged on the bottom position place in sampling bottle by bottle cap and plug, the other end of sample lines is together with the 3rd port UNICOM of four way ball valve, first port of four way ball valve is connected with the Sampling Interface of transformer station SF6 equipment, 4th port of four way ball valve is connected with and vacuumizes interface, vacuumize interface to be connected together by the air intake of gas exhaust piping and vacuum pump, the gas outlet of vacuum pump is connected together by molecular sieve filter and filtration flow container and exhaust valve port successively, gas exhaust piping is provided with solenoid valve.
Vacuum-pumping tube is respectively arranged with the second variable valve and the second rain glass, sample lines is respectively arranged with the first variable valve and the first rain glass, gas exhaust piping is provided with vacuum meter.
The utility model is simple to operation, gas sampling efficiently and accurately, after carrying out purification filtering process, reaches nontoxic discharge, protect the health of environment and operating personnel to the gas washing vacuumized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of sampling system of transformer station SF6 equipment, comprise vacuum pump 14, sampling bottle 6 and Drexel bottle 7, sampling bottle 6 is arranged in Drexel bottle 7, sampling bottle 6 is that opening is arranged, the bottleneck of Drexel bottle 7 is provided with bottle cap and plug, one end of vacuum-pumping tube 8 is arranged on the bottle mouth position of Drexel bottle 7 by bottle cap and plug, the other end of vacuum-pumping tube 8 is together with the second port UNICOM of four way ball valve 4, one end of sample lines 11 is arranged on the bottom position place in sampling bottle 6 by bottle cap and plug, the other end of sample lines 11 is together with the 3rd port UNICOM of four way ball valve 4, first port of four way ball valve 4 is connected with the Sampling Interface 1 of transformer station SF6 equipment, 4th port of four way ball valve 4 is connected with and vacuumizes interface 2, vacuumize interface 2 to be connected together by the air intake of gas exhaust piping 18 with vacuum pump 14, the gas outlet of vacuum pump 14 is connected together with exhaust valve port 17 by molecular sieve filter 15 and filtration flow container 16 successively, gas exhaust piping 18 is provided with solenoid valve 12.
