Example Embodiment
[0036] Example one, such as figure 1 As shown, the T-shaped shunt device on the main power supply line disclosed in this embodiment mainly includes an I-shaped T-shaped connector 1, a butt joint 2 and an I-shaped linear connection terminal 3.
[0037] The type I T connector 1 is an integral piece of the type I T-shaped inner conductor and the type I T-shaped hard insulating sleeve 11 embedded with the I-type T-shaped inner conductor 12, and the I-type T-shaped hard insulating sleeve 11 has three directions The length is greater than the length of the I-shaped T-shaped inner conductor 12, and all three ports form an arc extinguishing chamber. The three ports of the I-shaped T-shaped inner conductor 12 are all threaded connection structures with internal threaded holes, and the screw threads at both ends of the head are in opposite directions.
[0038] The butt joint 2 is an integral piece of an internal conductor 21 and a hard insulator 22 embedded with the internal conductor 21. Th...
Example Embodiment
[0044] Example two, such as figure 2 As shown, the T-shaped shunt device on the main power supply line disclosed in this embodiment mainly includes a type II T connector 1a, a butt joint 2 and a type II linear connection terminal 3a. The type II T connector 1a is similar to the first embodiment. The difference between the Type I T connector 1 is that the rod connection structure of the T type inner conductor is an external threaded head. The difference between the Type II linear connection terminal 3a and the Type I linear connection terminal 3 in the first embodiment is that the two ends of the internal conductor The connection structure is all internally threaded holes, and the diameter of the outer wall of the external hard insulation sleeve arc extinguishing is smaller than the diameter of the outer wall of the cable connection. The butt joint 2 is inverted with the arrangement in the first embodiment. The other structures and operations of this embodiment are the same as ...
Example Embodiment
[0045] Example three, such as image 3 As shown, the T-shaped shunt device on the main power supply line disclosed in this embodiment mainly includes a type III T connector 1b, a butt joint 2 and a type II linear connection terminal 3a, and the T type interior of the type III T connector 1b The connection structure of the three connecting ends of the conductor is an external thread head, and the inner diameter of the three ports of the T-shaped hard insulating sleeve is larger than the outer diameter of the external thread head. The other structures and operations of this embodiment are the same as the second embodiment.
