Description
Technical field
The utility model relates to technical field of power systems, and particularly one is used for SF
6the gas distributing device that gaseous mass detects.
Background technology
Sulfur hexafluoride (SF
6) gas T&B, it is the artificial inert gas that France two chemist Moissan and Lebeau synthesized in 1900, and before and after 1940, US military uses it for Manhattan project (core is military).Nineteen forty-seven, provider used.Current SF
6gas is mainly used in power industry.SF
6gas is used for electrical equipment as insulation and/or arc extinguishing.
The safety of the electrical equipment in right guarantee power industry, needs to carry out SF to electrical equipment usually
6the live detection of gas, a SF
6likely can there is fault in gaseous mass detecting instrument, so need by least two SF electrical equipment
6gaseous mass detecting instrument detects, but in current testing, can only pass through each SF successively
6gaseous mass detecting instrument detects an electrical equipment, each SF
6gaseous mass detecting instrument cannot realize detecting an electrical equipment simultaneously, causes detection efficiency too low, and SF when testing
6gas purging amount is excessive.
Utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model is: how to reduce gas purging amount.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of for SF
6the gas distributing device that gaseous mass detects, described gas distributing device comprises: gas cushion, draft tube and at least two escape pipes, the inside of described gas cushion is formed with cavity, described draft tube and escape pipe to be all located on described gas cushion and with described cavity connects, each escape pipe is equipped with flow stabilizing valve.
The internal diameter of described draft tube is the preset multiple of the internal diameter of described escape pipe, and described preset multiple is greater than 1.
Wherein, each escape pipe all with a SF
6gaseous mass detecting instrument connects.
Wherein, described draft tube is connected with electrical equipment to be detected.
Wherein, described flow stabilizing valve is closed type valve.
Wherein, described draft tube is three.
(3) beneficial effect
The utility model by arranging gas cushion, draft tube and at least two escape pipes, and each escape pipe is equipped with flow stabilizing valve, makes at least two SF
6gaseous mass detecting instrument can detect simultaneously, improves detection efficiency, and decreases gas purging amount.
Accompanying drawing explanation
Fig. 1 be a kind of embodiment of the utility model for SF
6the structural representation of the gas distributing device that gaseous mass detects.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
Below there are three draft tube so that the utility model to be described, but do not limit protection domain of the present utility model.Fig. 1 be a kind of embodiment of the utility model for SF
6the structural representation of the gas distributing device that gaseous mass detects; With reference to Fig. 1, described gas distributing device comprises: gas cushion 1, draft tube 2 and three escape pipes 3, the inside of described gas cushion 1 is formed with cavity (not shown), described draft tube 2 and escape pipe 3 to be all located on described gas cushion 1 and with described cavity connects, each escape pipe 3 is equipped with flow stabilizing valve 4.
For ensureing the intake efficiency of gas cushion 1, the internal diameter of described draft tube 2 is the preset multiple of the internal diameter of described escape pipe 3, and described preset multiple is greater than 1.
For realize detect simultaneously, preferably, each escape pipe 3 all with a SF
6gaseous mass detecting instrument 5 connects, wherein, and described SF
6gaseous mass detecting instrument 5 is existing instrument, and the utility model is not to SF
6gaseous mass detecting instrument 5 does any improvement.
Preferably, described draft tube 2 is connected with electrical equipment 6 to be detected.
SF is not connected for preventing escape pipe 3
6during gaseous mass detecting instrument 5, SF
6there is leakage situation in gas, preferably, described flow stabilizing valve 4 is closed type valve.
The principle of work of the present embodiment is: open at least two flow stabilizing valves 4, the SF in electrical equipment 6 to be detected
6gas enters the cavity of described gas cushion 1 by draft tube 2, the SF in the cavity of described gas cushion 1
6gas enters corresponding SF through each flow stabilizing valve 4 be unlocked
6gaseous mass detecting instrument 5, corresponding SF
6gaseous mass detecting instrument 5 detects simultaneously.
Above embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill of relevant technical field; when not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
