Embodiment
For the purpose of this utility model, feature are become apparent, provide preferred embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail.
A kind of stress cone proving installation that the utility model one embodiment provides, please in the lump referring to figs. 2 and 3.
This stress cone proving installation T is used for stress cone rubber parts 1, and stress cone proving installation T comprises fast connector 2, conductor, test cable 4, equal cover 5, epoxy bushing 8, cylindrical shell 14 and gas 11.
The endoporus aperture of stress cone rubber parts 1 and the line of test cable 4 directly mate, and stress cone rubber parts 1 string is enclosed within on the test cable 4, the two ends that make the two ends of test cable 4 stretch out stress cone rubber parts 1 respectively.
Conductor comprises sealing conductor 6 and bonding conductor 7, and above-mentioned both are connected to the two ends of above-mentioned fast connector 2, and an end of test cable 4 is connected in the other end of bonding conductor 7.The material of conductor for example is a cable copper core.The end that the other end of sealing conductor 6 is connected in epoxy bushing 8 forms test terminal 3.
For preventing owing to tip protrusion causes electric field distortion, equal cover 5 is set is arranged at the end of sealing conductor 6 away from fast connector 2, make the Electric Field Distribution at test terminal 3 places more even.
Cylindrical shell 14 is located on above-mentioned equal cover 5 and the outer of above-mentioned epoxy bushing 8 surrounds outer cavity 12, and establishes outer cavity vacuum orifice 9.
Gas 11 is filled in the above-mentioned outer cavity 12 to play insulating effect, and wherein, above-mentioned gas 11 comprises SF6 gas or N2 gas.The other end of test cable 4 stretches out above-mentioned cylindrical shell 14 and connects an end of basic cable 15, the other end of basic cable 15 is put equipment D as test block live end and the office of being connected be used for discharge.Wherein, test cable 4 is connected by water terminal W with basic cable 15.Above-mentioned test cable 4, above-mentioned bonding conductor 7, above-mentioned fast connector 2, above-mentioned sealing conductor 6 and above-mentioned equal cover 5 occupy on the above-mentioned cylindrical shell central shaft M.Preferable, roller 16 can be set on the cylindrical shell 14 make stress cone proving installation T be convenient to move.
