Detailed Description

The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.

As shown in fig. 1 and 2, a transformer bushing of the present embodiment includes a housing 1, a conductive rod 2, a damper pad 3, and a locking assembly 4, where the housing 1 includes a first housing 11 and a second housing 12, the damper pad 3 is disposed between the first housing 11 and the second housing 12, and the conductive rod 2 penetrates through the housing 1. The conducting rod 2 comprises a first rod body 21 and a second rod body 22, the first rod body 21 is connected with the second rod body 22, the diameter of the first rod body 21 is smaller than that of the second rod body 22, the first rod body is made of copper, and the second rod body is made of aluminum. The locking assemblies 4 are arranged in the accommodating grooves 13 at the two ends of the shell 1, each locking assembly 4 comprises a nut 41, and the nuts 41 are in threaded connection with the two ends of the conducting rod 2 to lock the first shell 11 and the second shell 12. Among the above-mentioned technical scheme, through set up shock pad 3 between first, the second casing, can cushion the transformer vibrations, reduce vibrations and transmit for first casing 11. Through adopting copper and aluminium to make first body of rod 21 and second body of rod 22 respectively, can reduce material cost, first body of rod 21 and second body of rod 22 pass through welded connection. The diameter of the second rod 22 is larger than that of the first rod 21, so that the potential difference between the first rod and the second rod can be reduced. By providing the locking assembly 4, the conductive rod 2 and the housing can be locked by the nut 41. By the technical scheme, the cost of the sleeve can be effectively reduced; in addition, the vibration of the transformer can be reduced, and the transformer is convenient to transmit, assemble and install.

In this embodiment, the first housing 11 is provided with the step portion 14, and the end of the second rod 22 abuts against the step portion 14, so that when the conducting rod 2 is installed, the conducting rod can be limited by the step portion 14, and the assembly is convenient.
