Description
（One）, technical field：It is more particularly to a kind of for component measuring instrument the present invention relates to a kind of gas collecting device
Gas collecting device.
（Two）, background technology：The traditional dielectric of electrical equipment and arc-extinguishing medium are insulating oils, and this insulating oil has
The insulation characterisitic more much higher than air intensity, specific heat ratio air are twice, and have convection properties after being heated, so it is in electricity
Not only dielectric had been done in gas equipment but also and cooling medium.But the weakness of this insulating oil maximum is exactly flammable, is set when electrically
It is standby Yi Dan be damaged short circuit when, it is most likely that there is electric arc, and insulating oil can be ignited and cause big fire by high arc temperature.
With people's insulation excellent to SF6 gases, the understanding of arc extinction performance, oil circuit breaker oneself through gradually exhausted by SF6 gases
Edge device for switching is replaced, at present, the technical parameters of various SF6 air insulating devices oneself reached very high level.In middle pressure
Field, SF6 switches have become the Two Mainstays run neck and neck with vacuum switch；In high pressure, super-pressure and extra-high voltage field, SF6
Gas almost becomes unique insulation and the arc-extinguishing medium of breaker and electric power GIS.Stabilizer pole of SF6 gases itself has very high
Dielectric strength and arc extinguishing ability.But the stability and reliability of SF6 electrical equipments depend entirely on the clarity of SF6 gases.
In many cases, SF6 gases in on-site electrical equipment and not always pure, if being mixed with impurity in SF6 gases, up to not
To defined standard, then its arc extinguishing and insulation characterisitic will be greatly reduced.In 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 gases is destroyed, work as moisture
In the presence of oxygen, these decomposition products can further react again with electrode material, moisture etc. generates sufficiently complex more of component
Kind compound.This not only results in the performance deterioration of organic insulation inside equipment or corrosion of metal, causes apparatus insulated
Hydraulic performance decline, and serious adverse consequences can be brought to electrical equipment and the person.Therefore to SF6 gases in SF6 electrical equipments
The monitoring of purity is essential.
Existing gas component measuring instrument is usually the component of on-line measurement SF6 gases, before measurement, in gas collecting device
The moisture contained can influence the accuracy measured.
