Description
Technical field
The utility model is related to the electrical connection arrangement of safe level, is particularly suitable for but is not limited only to electrically connecting of nuclear power plant
Connection device.
Background technology
With the development of e measurement technology, the use of the equipment such as measuring instrument and instrument is more and more extensive, and these equipment one
As be required for being connected to signal cable by electrical connection arrangement, therefore electrical connection arrangement creates in industrial interconnection technique
Very important effect.Especially under special environment condition, such as nuclear power plant, the performance of electrical connection arrangement generally all can
There is higher requirement, the connection of electrical connection arrangement must be effective rapidly, prevents operator to be excessively exposed to sensitizing range.With
When, the electrical connection arrangement of nuclear power plant is in addition to working it is necessary to earthquake, loss of-coolant accident (LOCA) can be sustained under the conditions of nominal situation
（LOCA）And the condition such as irradiation operating mode, thus ensureing the electrical connection under severe accident conditions.
Traditional safe level electrical connection arrangement is generally adopted by single axial sealing, and this structure is being dismantled back every time
Pad must be changed, pad is usually quality of rubber materials, is easily damaged in installation process, and installation quality is not easy when dress
To ensureing, and only together seal, be difficult to sustain long radiation, the high temperature after LOCA accident and heat ageing, finally
Lead to Joint failure.
Utility model content
The utility model provides a kind of electrical connection arrangement, to provide more reliable sealing and quick positioning, makes operation
Personnel are exposed in sensitizing range the short time as far as possible, ensure the safety of operating personnel.
Electrical connection arrangement of the present utility model, including the diametrically ecto-entad cover for seat that mutually socket joint connects successively,
Patch set and wire clamp, the end of wire clamp is connected with tail-hood.Cover for seat is coordinated in section with the socket joint patching set, is provided with cover for seat inwall
One circular step structure, and in this ledge structure and patch set bell end between be combined with the first sealing structure, cover for seat with connect
It is additionally provided with second seals structure between the socket joint cooperation section of sleeve；Also it is combined with the shell of locking locking structure in the outside of cover for seat；
