When in use, the anchor ears 3 are arranged on the surfaces of the two wires 2, the steel cable 5 or the plate spring 52 is arranged between the anchor ears 3, the connecting strength and the flexibility are realized, the expansion coefficient of the cable is consistent, the unloading purpose is achieved, the service life and the power supply reliability of the copper-aluminum transition joint are improved, when the copper-aluminum transition joint is electrified and used, the connecting part of the wires 2 generates heat through overflowing, the temperature inside the shell 1 is increased, heat is transferred to the aluminum block 14 through the heat conducting rod 15, the aluminum block 14 expands when heated, the volume is increased, and because the aluminum block 14 is positioned in the sealing cavity 71, when the volume of the aluminum block 14 is increased, the pressure inside the sealing cavity 71 is increased, so that the plate body I17 is pushed to move downwards through pressure, the rotating plate I20 is driven to further rotate through the action of the spring I18 and the plate II 19, the clamping strength of the elastic plate 21 is improved, and when the temperature inside the shell 1 is increased, the lead 2 is also heated to expand, so that the lead is connected with the elastic plate 21 more tightly, and simultaneously the air bag 24 is pressed, so that the internal pressure of the air bag is increased, at the moment, the pressure of the air bag 24 is higher than the pressure in the sealing cavity 71, and simultaneously, the plate body one 17 moves downwards to play a role of a piston, air in the air bag 24 is sucked into the sealing cavity 71 through the air conveying pipe 26 and the air inlet hose 27, so that the air bag 24 is prevented from expanding and crushing the lead 2 while the sealing performance is ensured, when the temperature of the lead 2 is gradually reduced, the air bag 24 is contracted, at the moment, the pressure is not applied to the air bag 24, the internal pressure of the air bag 24 is lower than the pressure in the sealing cavity 71, and at the moment, the internal temperature of the shell 1 is also gradually reduced, the volume of the aluminum block 14 is gradually reduced, the pressure of the sealing cavity 71 is gradually reduced, and the pressure on the spring one 18 is reduced, so that the elastic restoring force of the plate body one 18 pushes the plate body 17 to restore, in the resetting process of the first plate body 17, gas is discharged into the air bag 24 through the gas outlet hose 28 and the gas pipe 26 to be kept attached to the lead 2, so that the air bag 24 can adapt to expansion and contraction of the lead 2 and expansion of leads made of different materials through arrangement of the air bag 24, the aluminum block 14 and the sealing cavity 71, and the service life of the air bag 24 is prolonged while the sealing performance is ensured.
Through the removal of plate body 17, still drive the electric contact 29 that plate body 17 lower surface is connected and remove, as shown in fig. 5, it is too big to lead to aluminium pig 14 inflation when the inside high temperature of casing 1 to when driving electric contact 29 that plate body 17 lower surface is connected and the electric contact 29 contact in the box 7, alarm 30 sends out the police dispatch newspaper, can make the early warning before the device damages, in time informs the staff and corresponds the operation, avoids damaging.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
