Abstract
The utility model relates to a connecting device for SF6 equipment test and particularly relates to an SF6 multifunctional connecting device. The SF6 multifunctional connecting device comprises a gas inlet pipe, wherein three gas outlet pipes are connected at the tail end of the gas inlet pipe side by side, a gas path control valve is arranged on the pipe body of each gas outlet pipe, and the outside diameters of the gas inlet pipe and the gas outlet pipes are 4 mm. The SF6 multifunctional connecting device provided by the utility model can be used for simultaneously performing multiple test items of SF6 equipment, the duration for performing three tests (SF6 purity test, SF6 humidity test and SF6 decomposition product test) is only 40 minutes, the original duration for performing the three tests is 90 minutes, thus, the used time of the test is obviously shortened; and moreover, the gas inlet pipe and the gas outlet pipes are preferably gas pipes with outside diameters of 4 mm, and the SF6 multifunctional connecting device can be conveniently connected with the SF6 equipment and a test instrument through polytetrafluoroethylene pipes.
Description
Technical field
The utility model relates to for SF
6the coupling arrangement of testing of equipment, is specially SF
6multifunctional jointing device.
Background technology
Along with the development of Chinese society economy, electricity needs rapid growth, SF
6gas, as good insulation and arc-extinguishing medium, has been widely applied in the electrical equipments such as high-voltage switch gear, transformer, mutual inductor, combined electrical apparatus (GIS).To SF
6when equipment test, because pilot project is many, each testing tool all needs and SF
6equipment connection, like this SF
6equipment just needs to be repeatedly connected with testing tool, has caused test job amount large, and the test job time is long, and due to SF
6device fabrication producer difference, device type difference, pilot project are not equal, cause testing tool and SF
6the connection difficulty of equipment.
Summary of the invention
The utility model is in order to solve SF
6when equipment test, SF
6equipment need to repeatedly connect and be connected difficult problem with testing tool, and SF is provided
6multifunctional jointing device.
The utility model is to adopt following technical scheme to realize: SF
6multifunctional jointing device, comprises draft tube, and the tail end of draft tube is connected with at least two escape pipes side by side, is also provided with gas path control valve on the body of each escape pipe.
When use, by SF
6the head end of the draft tube of multifunctional jointing device and on-the-spot tested SF
6equipment connection, by SF
6the escape pipe of multifunctional jointing device and SF
6humidity measurement instrument, SF
6decomposition product tester or SF
6the connections such as purity test instrument, this SF
6multifunctional jointing device can be realized SF
6multiple pilot projects of equipment are carried out simultaneously, SF
6equipment does not need repeatedly to connect, and after completing when a test wherein, can cut off gas circuit by the gas path control valve on escape pipe, saves SF
6gas, has also reduced the pollution to atmosphere.
Above-mentioned SF
6multifunctional jointing device, the quantity of the escape pipe that the tail end of draft tube connects is side by side three, SF
6the pilot project of equipment is generally three, and three escape pipes respectively and SF
6humidity measurement instrument, SF
6decomposition product tester and SF
6purity test instrument connects.
Above-mentioned SF
6multifunctional jointing device, draft tube and escape pipe are that external diameter is the tracheae of 4mm, can be easily by polyfluortetraethylene pipe and SF
6equipment is connected with testing tool.
The SF that the utility model provides
6multifunctional jointing device can be realized SF
6multiple pilot projects of equipment are carried out simultaneously, and carry out three test (SF
6purity test, SF
6humidity Detection and SF
6decomposition product test) time only need 40 minutes, the time of original three tests is 90 minutes, visible, tests the time used obviously to reduce; And draft tube and escape pipe are preferably the tracheae that external diameter is 4mm, can be easily by polyfluortetraethylene pipe and SF
6equipment is connected with testing tool.
