Description
(1), technical field: the present invention relates to a kind of gas collecting device, particularly to a kind of gas for component measuring instrument
Harvester.
(2), background technology: dielectric and arc-extinguishing medium that electrical equipment is traditional are insulating oils, and this insulating oil has
The insulation characterisitic more much higher than air intensity, its specific heat ratio air is twice, and has convection properties after being heated, so it is at electricity
Gas equipment had not only done dielectric but also cooling medium of holding concurrently.But the weakness of this insulating oil maximum is exactly flammable, when electrically setting
Standby once the short circuit that is damaged, it is most likely that electric arc to occur, and insulating oil can be ignited and cause big fire by high arc temperature.
Along with people are to the excellent insulation of SF6 gas, the understanding of arc extinction performance, oil circuit breaker oneself through gradually exhausted by SF6 gas
Edge device for switching is replaced, at present, the technical parameter of various SF6 air insulating devices oneself reached the highest level.In middle pressure
Field, SF6 switch has become the Two Mainstays run neck and neck with vacuum switch；At high pressure, supertension and extra-high voltage field, SF6
Gas almost becomes chopper and unique insulation of electric power GIS and arc-extinguishing medium.The stabilizer pole of SF6 gas own, has the highest
Dielectric strength and arc extinguishing ability.But, the stability of SF6 electrical equipment and reliability depend entirely on the clarity of SF6 gas.
Under many circumstances, SF6 gas in on-site electrical equipment is the purest, if being mixed with impurity in SF6 gas, reaches not
Standard to regulation, then its arc extinguishing and insulation characterisitic will be greatly reduced.When high-current on-off due to strong electric discharge
Condition, SF6 can decompose generation ion and atomic group, and at the end of discharge process, wherein the overwhelming majority can be combined into again again
SF6.Under the conditions of thermal ionization, ion and atomic group respond are extremely strong, if the purity of SF6 gas is destroyed, work as moisture
In the presence of oxygen, these catabolites again can be sufficiently complex many with the reaction generation component further such as electrode material, moisture
Plant compound.This performance degradation not only resulting in device interior organic insulation or corrosion of metal, cause apparatus insulated
Hydraulic performance decline, and electrical equipment and the person can be brought serious adverse consequences.Therefore to SF6 gas in SF6 electrical equipment
The monitoring of purity is essential.
Existing gas component measuring instrument is usually the component of on-line measurement SF6 gas, before measurement, in gas collecting device
The moisture contained can affect the accuracy of measurement.
(3), summary of the invention:
The technical problem to be solved in the present invention is: provide a kind of gas collecting device for component measuring instrument, this gas collecting
Can deliver gas to during device busy state in component measuring instrument, therein can be absorbed in a non-operative state
Moisture, prepares for measurement next time, is effectively increased the accuracy that gas component is measured.
