6the qualitative leak locator of gasometry.The present invention can be fixedly mounted on doubtful leakage electric equipment lower end for a long time, carries out uninterrupted gas continuous sampling, and gas channeling is accurate, collects with strong points, and collecting amount is comprehensive, and be swift in response, efficiency is high.
Description
Technical field
The invention belongs to electrical equipment detection field, be specifically related to combined electrical apparatus SF
6gas leakage hunting apparatus.It is widely used in large-scale let-down stations, generating plant, power station combined electrical apparatus (GIS) insulating medium SF
6weigh in the pipeline of gas recovery checkout equipment gas in gas and other field.
Background technology
Work as SF
6during gases did escape the relevant personnel can only on equipment or scene utilize leakage detecting instrument to hunt leak on the spot, the length of instrument probe and the locomotivity of personnel, limited flexibility, and there is unsafe factor, at all cannot continual, targetedly leak source or micro-leak source are accurately caught, are located.
SF in electric system GIS and isolating switch insulating medium
6the widespread use of gas, SF
6gas is in operation to reveal and also can exists simultaneously, and except the leakage value allowed, it is definitely unallowed in equipment running process that abnormal moderate, severe leak even micro-leakage, and personnel are in operation must the SF of accurate point inspection equipments
6force value, carry out the comparison between time interval and other conditions, if occur to leak or automatic alarm, accurate leak source must be found and then safeguard rapidly, which substantially increases the work difficulty of Leakage Gas specific aim inspection, harsh accuracy makes manual detection increase the huge muscle power of personnel, energy, the paying of time, and accuracy rate is not high, affect personnel health, take time and effort but poor effect.
Summary of the invention
In order to SF can be detected in time
6the leakage of gas, the invention provides electrical equipment SF
6gas leakage hunting apparatus.
Technical scheme of the present invention: electrical equipment SF
6gas leakage hunting apparatus, is characterized in that by pneumatic trough, mozzle, gas collection bucket and SF
6the qualitative leak locator composition of gasometry, pneumatic trough is arranged on the top of mozzle, and mozzle is arranged on above gas collection bucket, in 105 degree of angles between pneumatic trough and mozzle, the connection SF of gas collection bucket
6the qualitative leak locator of gasometry.
A kind of SF
6gas collection method, as the inner SF of electric system combined electrical apparatus
6during Leakage Gas, according to specific gravity of gas, SF
6gas can be assembled gradually at electric system combined electrical apparatus orlop; SF simultaneously
6air in pneumatic trough, in pneumatic trough, squeezes outside pneumatic trough by free flow of gas, is all SF in pneumatic trough
6gas, the SF in pneumatic trough
6gas flows into mozzle along with the pneumatic trough tilted glides; SF
6gas enters in mozzle, is discharged by air from pod apertures simultaneously; SF
6gas is finally gathered in SF
6in gas collection bucket.
Principle of work of the present invention is: due to SF
6gas molecule is the neutral molecule combined with the same sulphur atom of covalent bond form by six fluorine atoms, and its atomic weight is 146, is five times of air atomic weight, and SF in the normal state
6gas molecule can not occur to dissolve and react with air;
As the inner SF of electric system combined electrical apparatus
6during Leakage Gas, SF
6gas can be assembled gradually at electric system combined electrical apparatus orlop; SF simultaneously
6air in pvc pipe groove, in pvc pipe groove, squeezes outside pvc pipe groove by free flow of gas, is all SF in pvc pipe groove
6gas, the SF in pvc pipe groove
6gas flows into mozzle along with the pvc pipe groove tilted glides; SF
6gas enters in mozzle, is discharged by air from pod apertures simultaneously; SF
6gas is finally gathered in SF
6in gas collection bucket.
The present invention be directed to doubtful leak source position installation orientation collect means facility, be the invention of effective novel means and the extension that gas leaks inspection machine, utilize pilot conduits to carry out gas sample collection, (micro-) gas leakage carries out analysis after leaking the sampling of terminal air accumulation basin by the heavy gas channeling pipeline of cross type and show whether equipment has gas to disengage and leakiness.
The present invention and conventional seals pipeline SF
6gas reclaims and compares, and the present invention is more direct, safer, more motor-driven, simpler and easy, more natural, avoids the pattern that the simple open-type of device end gets gas simultaneously.
The present invention uses material easy, with low cost, is easy to processing, becomes the combined pipeline element that is direct, the most best, that utilize cheap material of leak test plant.
The present invention can be fixedly mounted on doubtful leakage electric equipment lower end for a long time, carries out uninterrupted gas continuous sampling, and gas channeling is accurate, collects with strong points, and collecting amount is comprehensive, and be swift in response, efficiency is high.
