Description
Technical field
This utility model provides SF in a kind of electrical equipment6Solid decomposition product sampler, belongs to SF6Collection and confinement of gases technology
Field.
Background technology
SF6Gas, because of advantages such as its stable chemical property and excellent insulation arc extinction performances, is widely used in electrically
Equipment.When equipment generation defect fault, SF6Gas will decompose, and participates in reaction when having metal electrode or solid insulating material
Time, solid decomposition product (such as metal fluoride, metal-oxide etc.) can be produced, these solid particles or be distributed in SF6Gas
In, or it is scattered in device interior surface.Generally, for SF in collecting device6Solid decomposition product, it is necessary to equipment is solved
Body, this can only be in the case of equipment fault defect be extremely serious.The equipment that fault severity level is not up to disintegrated, then without
Method is collected solid decomposition product and is analyzed.
Utility model content
The purpose of this utility model is to provide that one can solve the problems referred to above, need not to carry out equipment to disintegrate just can be right
SF6Solid decomposition product is collected, SF in the electrical equipment of excellent working performance6Solid decomposition product sampler.Its technical side
Case is:
SF in a kind of electrical equipment6Solid decomposition product sampler, including lower bottom base and the upper cover of hollow, both screw threads are even
Connecing, be provided with sealing ring at connecting end surface, the bottom of lower bottom base is provided with gas outlet, above covers and is provided with air inlet, it is characterised in that under:
Base and upper cover material selection politef；Setting up filter membrane and support, wherein filter membrane uses aperture to be having of 0.45 μm
Machine film, support is supported on the boss being positioned at lower bottom base inwall upper end, support is evenly equipped with the pore of a diameter of 2mm, filter membrane
Being placed on support, the step boss end count seal on upper cover inwall is pressed on filter membrane；It is interior that upper cover docks with lower bottom base
Chamber diameter is d1, the height of the bottom surface distance filter membrane of upper cover is h1, the inner chamber of lower bottom base constitutes funnel-form chamber with the bottom surface of support
Body, the top half of this cavity cylindrically, a diameter of d1, height be h2, middle part is round table-like, and height is h3, tapering be 45 °,
The internal diameter of gas outlet and air inlet is d2, and h1=h2, 2h3=d1-d2, the vapor permeation area s=0.785d of filter membrane1 2, air inlet
The inwall of mouth is provided with screw thread, pitch 3mm, degree of depth 2mm.
SF in described electrical equipment6Solid decomposition product sampler, diameter d1For 20-30mm, internal diameter is d2For 5-7mm,
Highly h1For 5-6mm, height is h2For 5-6mm, highly h3For 8-10mm.
This utility model compared with prior art, has an advantage in that:
1, various piece in the frustum cone structure of 45 ° of cone angles below sampler, air inlet inwall are arranged screw thread and cavity
Organic cooperation of size so that after the air-flow of filtered enters sampler, eddy current reaches optimum state above filter membrane 6,
Solid particle is made more uniformly to be attached on filter membrane.
2, the organic membrane that filter membrane selects aperture to be 0.45 μm, can at utmost intercept solid particle and be unlikely to cause
The micropore of granule blocking organic membrane；Sampler material uses politef, as the SF of certain pressure6When gas passes through, have
Certain tolerance intensity, and material does not results in interference effect to sample composition analysis.
3, need not equipment is disintegrated, work as SF6When gas is by solid air-sampler, the solid being suspended in gas
Grain is trapped within the filter membrane in sampler, by the solid particulate components of filter membrane surface is analyzed research, i.e. can be appreciated that
SF during equipment fault6Decompose the solid decomposition product produced, excellent working performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
