The utility model discloses can flow the gaseous realization of the sulfur hexafluoride in the GIS equipment and test, the processing is collected to the gas after the gaseous on line analyzer of sulfur hexafluoride tests, changes present on line analyzer and measures non flowing gas and bring very big detection error problem, has guaranteed sample detecting's representativeness to regularly carry out the recovery processing to the gas among the collection device, reached the environmental protection requirement. The utility model is suitable for an use sulfur hexafluoride for GIS the equipment insulating and arc -extinguishing medium, can use on line under power failure, the electrified circumstances.
Description
Technical field
This utility model relates to on-line monitoring and the collection device of sulfur hexafluoride gas in a kind of GIS device, belongs to substation field detection technique field.
Background technology
By the sulfur hexafluoride gas in GIS power equipment in transformer station carries out on-line monitoring, the operation conditions of monitoring GIS device has been a kind of generally acknowledged discovering device fault, the effective means ensureing equipment safety operation.
At present, in power industry requirement unit with good conditionsi GIS device to be filled, the in-line analyzer of sulfur hexafluoride gas, comprises the test of sulfur hexafluoride gas humidity, purity, catabolite.The scheme of test takes to draw pipeline in equipment, and the sensor of in-line analyzer is installed on pipeline, do not take back equipment with pipeline, the pipeline of the method connects simple, there is no collection and confinement of gases link, but the sulfur hexafluoride gas of test is immobilising dead gas, survey is all the gas in sensor always, the gas-condition of whole air chamber can not be represented, the error that so may result in test result is bigger, without reference to value, thus the testing crew judgement to status of equipment can be misled, cause certain potential safety hazard.
Based on above-mentioned condition, the greenhouse effect of sulfur hexafluoride gas relatively big for the error of current in-line analyzer test result and the hypertoxicity of sulfur hexafluoride decomposition product, develop the on-line monitoring of sulfur hexafluoride gas in a kind of GIS device the most necessary.
Summary of the invention
The purpose of this utility model is, in order to improve accuracy and the reliability of test result, and not emission greenhouse gas, meet the requirement of environmental protection, discloses on-line monitoring and the collection device of sulfur hexafluoride gas in a kind of GIS device.
The technical solution of the utility model is, in a kind of GIS device, on-line monitoring and the collection device of sulfur hexafluoride gas include GIS device, Gas sampling joint and valve, sulfur hexafluoride gas in-line analyzer, sulfur hexafluoride gas analysis result monitor supervision platform, collection and confinement of gases valve and gas collector.The input port of Gas sampling joint and valve connects the output port of GIS device, Gas sampling joint and valve and connects sulfur hexafluoride gas in-line analyzer, and transmits analysis result to sulfur hexafluoride gas analysis result monitor supervision platform；The gas outlet of sulfur hexafluoride gas in-line analyzer is connected to gas collector by collection and confinement of gases valve, it is to avoid be directly discharged into air.
The on-line monitoring of sulfur hexafluoride gas and collection device in a kind of GIS device of this utility model, can be after the sulfur hexafluoride gas on-line testing in GIS device be complete, by in exhaust collection to the collection device of neighbouring several air chambers, and periodically the sulfur hexafluoride gas in collecting box is recycled to special processing center carries out purified treatment.
In GIS device when the on-line monitoring of sulfur hexafluoride gas and collection device work, by the sulfur hexafluoride gas in GIS device in transformer station, by special valve and joint, (gas on-line analyzer includes sulfur hexafluoride gas humidity to access gas on-line analyzer under power failure or electriferous state, purity and catabolite tester), the test result of in-line analyzer accesses sulfur hexafluoride gas analysis result monitor supervision platform, by collection and confinement of gases valve, the gas tested is connected to sulfur hexafluoride gas collection device from gas on-line analyzer again, and periodically the gas collected is recycled, thus substantially increase the representativeness of test sample, decrease the discharge of sulfur hexafluoride gas and catabolite thereof, realize environmental protection.
The beneficial effects of the utility model are, sulfur hexafluoride gas in GIS device can be realized flowing test by this utility model, gas after sulfur hexafluoride gas in-line analyzer is tested is collected processing, change current in-line analyzer measure not flowing gas and bring the biggest detection error problem, ensure that the representativeness of detection sample, and periodically the gas in collection device is recycled, reach environmental requirement.
This utility model be applicable to sulfur hexafluoride be insulation and the GIS device of arc-extinguishing medium, can having a power failure, charged in the case of use online.

Detailed description of the invention
Below in conjunction with embodiment and compare accompanying drawing this utility model is described in detail.
As shown in Figure 1, the on-line monitoring of sulfur hexafluoride gas and collection device in a kind of GIS device of the present embodiment, including GIS device 1, Gas sampling joint and valve 2, sulfur hexafluoride gas in-line analyzer 3, sulfur hexafluoride gas analysis result monitor supervision platform 4, collection and confinement of gases valve 5 and gas collector 6.
The input port of Gas sampling joint and valve 2 connects GIS device 1, the output port of Gas sampling joint and valve 2 connects sulfur hexafluoride gas in-line analyzer 3, and analysis result is transmitted to sulfur hexafluoride gas analysis result monitor supervision platform 4, the gas outlet of sulfur hexafluoride gas in-line analyzer 3 is connected to gas collector 6 by collection and confinement of gases valve 5, it is to avoid be directly discharged into air.
The sulfur hexafluoride gas taken out in GIS device, enters sulfur hexafluoride gas collection device through valve after on-line gas analysis instrument again, and gas analysis data can real time inspection at result monitor supervision platform.
