Description
technical field
The utility model relates to a kind of hyperchannel GIS sulfur hexafluoride moisture and decomposition product on-line measuring device, belongs to High-Voltage Electrical Appliances on-line monitoring technique field.
background technology
By to GIS(gas insulated combined electrical equipment) sulfur hexafluoride moisture and decomposition product test, monitoring GIS operation conditions has been a kind of generally acknowledged discovery GIS device fault, the effective means ensureing GIS device safe operation, but the shortcomings such as sampling operation is loaded down with trivial details, the effective difference of data that traditional power cut detection device exists, are difficult to realize the real-time oversight to GIS equipment operational condition.In recent years, what GIS sulfur hexafluoride moisture and decomposition product on-line monitoring technique detected as equipment outage analysis supplements and development, because it has the advantage of short, the continuous on-line monitoring of analytical cycle, the on-line monitoring to GIS device moisture and decomposition product and analysis can be realized, its application is for the fault of Timeliness coverage GIS, and that avoids accident has important effect.In addition, the online moisture of sulfur hexafluoride and decomposition product monitoring technology are that GIS device realizes prophylactic repair and excessively provides effective technical support to repair based on condition of component.On-the-spot on-line measuring device is used for automatically gathering, detecting sulfur hexafluoride gas moisture, usually be arranged on monitored equipment, on-site detecting device generally forms a set of detection system by sulfur hexafluoride gas harvester, automatic sampling apparatus, detecting sensor, gas counter sample device, data acquisition unit etc.
Now most of GIS sulfur hexafluoride moisture commercially and decomposition product content on-line analysis device can only be analyzed the single air chamber in GIS device, and a set of on-line analysis device can not be shared by multiple air chamber, need to detect as once run into multiple equipment or multiple air chamber, then particularly troublesome, require great effort time-consuming.
summary of the invention
The purpose of this utility model is, for the shortcoming that existing GIS sulfur hexafluoride moisture and decomposition product content on-line analysis device can only be analyzed the single air chamber in GIS device, the utility model proposes a kind of hyperchannel GIS sulfur hexafluoride moisture and decomposition product on-line measuring device.
Realizing the technical solution of the utility model is, this device utilizes the multiple sample introduction automatic transfer valves after gas collecting, through sulfur hexafluoride gas moisture and decomposition product sensor, auto thermal compensation processor, data collection and analysis, realize the difference to the same interval of GIS device or multiple air chamber (as air chambers such as isolating switch, current transformer, voltage transformer (VT), disconnectores) unified detection in order.
The utility model hyperchannel GIS sulfur hexafluoride moisture and decomposition product on-line measuring device are made up of sulfur hexafluoride three-way connection, gas collecting device, auto injection transfer valve, sulfur hexafluoride moisture and decomposition product sensor, temperature sensor, data acquisition unit, industrial computer, force (forcing) pump and counter sample transfer valve; The output port of sulfur hexafluoride three-way connection connects gas collecting device, the output port of gas collecting device passes into sulfur hexafluoride moisture and decomposition product sensor by auto injection transfer valve, enter temperature sensor again, moisture and decomposition product sensor and temperature sensor connection data collector, and access industrial computer by data acquisition unit; Temperature sensor outlet pipe adopts force (forcing) pump and counter sample transfer valve that the gas detected is taken back the air chamber of GIS device.
The utility model can by the detection special three-way joint of multiple for same interval air chamber, gas collecting device, auto injection transfer valve connects a sulfur hexafluoride moisture altogether and decomposition product sensor carries out sulfur hexafluoride moisture and decomposition product on-line analysis.
When using hyperchannel GIS sulfur hexafluoride moisture and the work of decomposition product on-line measuring device, sulfur hexafluoride gas in GIS device is undertaken gathering continuously or periodically by T-valve and gas collecting device, then the sulfur hexafluoride gas sample of collection is carried out moisture and decomposition product by sampling switching valve by manually pre-set order, temperature test, again the sulfur hexafluoride gas tested is returned the air chamber of sampling by force (forcing) pump and counter sample transfer valve, the result analyzed extremely is controlled and processing unit (comprising temperature compensation process) by data acquisition unit collection, again by the data access industrial computer after process, on-line monitoring is carried out by the monitoring software on computing machine.
The beneficial effects of the utility model are, the utility model hyperchannel GIS sulfur hexafluoride moisture and decomposition product on-line measuring device not only can share a set of to the different air chambers at the same interval of GIS device
onlineanalytical equipment carries out moisture and decomposition product analysis; To A, B, C three-phase gas-break switch near arrangement, only can also make quantitative test accurately with a set of on-line analysis device to sulfur hexafluoride moisture and decomposition product.This device is used in actual production and can be saved a large amount of purchase costs and manual maintenance workload, can widespread use in GIS device and gas-break switch operational application, fault diagnosis.
The utility model is applicable to online sulfur hexafluoride moisture and the decomposition product analysis of the different air chamber in the same interval of GIS device.
