Abstract

The invention relates to a universal gas sampling connector which comprises a connecting pipe connector, a transition pipe and sampling pipes. One end of the connecting pipe connector is communicated with a gas sampling pipe. The other end of the connecting pipe connector is communicated with the output end of the transition pipe. The input end of the transition pipe is provided with a plurality of ports of different calibers. Each port is connected with the corresponding sampling pipe. By converting an existing gas sampling connector into the universal SF6 gas sampling connector, the sampling connector installing time and the sampling connector replacing time are omitted, and the work efficiency is greatly improved.

Description

Universal gas sampling interface
Technical field
The present invention relates to a kind of Sampling Interface, particularly relate to a kind of universal gas sampling interface, be specially adapted to SF6 open type switch and GIS air chamber, belong to electric power application.
Background technique
Because producer is different, the sample tap caliber size of SF6 open type switch and GIS air chamber differs.Therefore, all more than 40 must be carried when tester carries out gas sampling and plant sample connection, bring much inconvenience to preparatory work, sampling work, housekeeping, waste a large amount of manpower and materials.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide a kind of universal gas sampling interface, solve the intricate operation problem caused due to sample tap size bore difference in prior art.
Technological scheme of the present invention is as follows:
Sampling Interface comprises Tube to tube fittings, transition tube and sampling pipe; One end of Tube to tube fittings with get tracheae and be communicated with, the other end of Tube to tube fittings is communicated with the output terminal of transition tube, and the input end of transition tube is provided with the different port of multiple bore, and each port connects corresponding sampling pipe respectively.
Described port and sampling pipe are respectively provided with three, and the external diameter of three sampling pipes is 28mm, 45mm and 47mm respectively.
Described Tube to tube fittings length 5mm, transition tube length 35mm, sampling pipe length 70 mm.
Described Tube to tube fittings is standard gauge, the size of Tube to tube fittings with get tracheae and match.
Described Tube to tube fittings internal diameter 3.6mm.
Advantageous effect of the present invention is as follows:
Raw-gas Sampling Interface is transformed into a kind of universal SF6 gas sampling interface, greatly increases work efficiency, achieve SF6 gas sampling nuclear interface standardizing; Staff only carries a kind of sampling joint can complete sampling work, simply efficiently; Eliminate and the Sampling Interface time is installed and changes Sampling Interface link; Reduce sampling work amount, sample collector reduces to 2 people by 4 people, reaches time saving and energy saving object; Safely, complete gas sample work fast, easily, overcome the skimble-scamble shortcoming of equipment sample cock specification of different model or producer, facilitate field sampling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1, Tube to tube fittings, 2, transition tube, 3, sampling pipe, 4, get tracheae.
Embodiment
Embodiment
As shown in Figure 1, Sampling Interface comprises Tube to tube fittings 1, transition tube 2 and sampling pipe 3, Tube to tube fittings length 5mm, transition tube length 35mm, sampling pipe length 70 mm; Tube to tube fittings is standard gauge, internal diameter 3.6mm, the size of Tube to tube fittings with get tracheae and match, one end of Tube to tube fittings with get tracheae 4 and be communicated with, the other end of Tube to tube fittings is communicated with the output terminal of transition tube, the input end of transition tube is provided with the different port of 3 bores, and each port connects corresponding sampling pipe respectively, and the external diameter of three sampling pipes is 28mm, 45mm and 47mm respectively.
During use, that 28mm, 45mm are connected with 28mm, 45mm and 47mm mouth of pipe of SF6 open type switch or GIS air chamber respectively with the sampling pipe of 47mm respectively by external diameter, scene is placed on after connecting, use for getting gas from now on, the other end due to Sampling Interface adopts unified standard gauge, and internal diameter 3.6 mm Tube to tube fittings, just need not carry sample connection when gas is got at scene of arriving like this, only need bring standard gauge, internal diameter 3.6 mm gets tracheae.
The present invention is applied in the micro-water test of certain electric substation 10 line switchings.
Staff was wasted time and energy when 30 air chambers carry out the test of micro-water to these 10 groups of switches totally in the past, and each air chamber is installed the Sampling Interface time and is 2 minutes, test 2 minutes, also will carries out gas sampling interface simultaneously and more change jobs, totally 120 minutes test time.
Above-mentioned 10 circuits are applied in by Sampling Interface of the present invention, wherein internal diameter is that the sampling pipe of 28mm is applied to ABB sample cock, internal diameter is that the sampling pipe of 74mm is applied to Shen height sample cock, eliminate and the Sampling Interface time is installed and changes Sampling Interface link, only 60 minutes used times, substantially increase working efficiency, obtain the consistent favorable comment of tester.
