Abstract
The present invention relates to a kind of universal gas sampling interface, which includes union nipple, transition conduit and sampling tube；One end of union nipple is connected with trachea is taken, the other end of union nipple is connected with the outfan of transition conduit, the input of transition conduit is provided with the different port of multiple bores, each port connects corresponding sampling tube respectively, raw-gas Sampling Interface is transformed into a kind of universal SF6 gas samplings interface by the present invention, eliminate the installation Sampling Interface time and change the Sampling Interface time, greatly improve work efficiency.
Description
Technical field
The present invention relates to a kind of Sampling Interface, more particularly to a kind of universal gas sampling interface, it is particularly well-suited to SF6 and opens
Open switch and GIS air chambers, belong to electric power application.
Background technology
As producer is different, the sample tap caliber size of SF6 open types switch and GIS air chambers differs.Therefore, testing crew
All of more than 40 must be carried when carrying out gas sampling and plants sample connection, bring perhaps to preparation, sampling work, housekeeping
How inconvenient, waste a large amount of manpower and materials.
Content of the invention
The present invention is directed to above-mentioned problems of the prior art, there is provided a kind of universal gas sampling interface, solves
In prior art as sample tap size bore is different caused intricate operation problem.
Technical scheme is as follows:
Sampling Interface includes union nipple, transition conduit and sampling tube；One end of union nipple is connected with trachea is taken, and adapter connects
The other end of head is connected with the outfan of transition conduit, and the input of transition conduit is provided with the different port of multiple bores, each port
Connect corresponding sampling tube respectively.
Described port and sampling tube are each provided with three, and the external diameter of three sampling tubes is 28mm, 45mm and 47mm respectively.
Described union nipple length 5mm, transition length of tube 35mm, sample 70 mm of length of tube.
Described union nipple is standard gauge, and the size of union nipple matches with trachea is taken.
Described union nipple internal diameter 3.6mm.
Advantages of the present invention effect is as follows：
Raw-gas Sampling Interface is transformed into a kind of universal SF6 gas samplings interface, work efficiency is greatly improved, is realized
SF6 gas sampling nuclear interface standardizings；Staff completes sampling work by only carrying a kind of sampling joint, simple efficient；
Eliminate the installation Sampling Interface time and change Sampling Interface link；Reduce sampling work amount, sample collector is reduced to 2 by 4 people
People, reaches time saving and energy saving purpose；Safety, gas sample work is quickly and conveniently completed, overcome setting for different model or producer
For the skimble-scamble shortcoming of sample cock specification, facilitate field investigation and sampling.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure, 1, union nipple, 2, transition conduit, 3, sampling tube, 4, take trachea.
Specific embodiment
Embodiment
As shown in figure 1, Sampling Interface includes union nipple 1, transition conduit 2 and sampling tube 3, union nipple length 5mm, transition
Length of tube 35mm, sample 70 mm of length of tube；Union nipple is standard gauge, internal diameter 3.6mm, the size of union nipple with take gas
Pipe matches, and one end of union nipple is connected with trachea 4 is taken, and the other end of union nipple is connected with the outfan of transition conduit, mistake
The input for crossing pipe is provided with 3 different ports of bore, and each port connects corresponding sampling tube respectively, outside three sampling tubes
Footpath is 28mm, 45mm and 47mm respectively.
During use, it is that the sampling tube of 28mm, 45mm and 47mm is switched with SF6 open types or GIS gas respectively respectively by external diameter
28mm, 45mm and 47mm mouth of pipe connection of room, is placed on scene after connection, for taking gas use from now on, due to Sampling Interface
The other end adopts unified standard gauge, 3.6 mm union nipples of internal diameter just to connect without carrying sampling when so taking gas to scene
Head, only need to take standard gauge, and 3.6 mm of internal diameter takes trachea.
The present invention is applied in the micro- water test of 10 line switchings of certain transformer station.
Staff was wasted time and energy when 30 air chambers carry out micro- water test to this 10 groups of switches totally in the past, and each air chamber is installed
The Sampling Interface time is 2 minutes, test more changes jobs for 2 minutes while being also performed to gas sampling interface, the testing time totally 120
Minute.
Applied in above-mentioned 10 circuits by Sampling Interface of the present invention, wherein internal diameter is applied to ABB for the sampling tube of 28mm
Sample cock, internal diameter are applied to the high sample cock in Shen for the sampling tube of 74mm, eliminate the installation Sampling Interface time and replacing is adopted
Sample interface link, only 60 minutes used times, substantially increases work efficiency, obtains the consistent favorable comment of testing crew.
