DETAILED DESCRIPTION

[0011] The utility model aims at the problem that the single-pole isolating switch cannot adapt to the thermal expansion and contraction of the tubular busbar when providing support for the tubular busbar, and provides a connection structure between the single-pole isolating switch and the end of the tubular busbar, such as Figure 1 As shown, it includes a single-pole disconnector support insulator 1, a single-pole disconnector terminal block 2, a tubular busbar 3, a tubular busbar end ball 4, a tubular busbar soft connection fitting 5, a conductive component 51, a tubular female sliding support component 6 and a tubular busbar conductive terminal block 7; the tubular female sliding support component 6 is provided with a slider 61, the tubular busbar conductive terminal block 7 is provided with an insulating component 72, and the insulating component 72 is provided with a slide groove 71; the single-pole disconnector terminal block 2 is fixed to the single-pole disconnector support support insulator 1, and is detachably fixedly connected to the tubular busbar conductive terminal block 7; the tubular female sliding support component 6 is fixedly connected to the tubular busbar end ball 4 of the tubular busbar 3, and the slider 61 on the tubular female sliding support component 6 is embedded in the slide groove 71; one end of the tubular busbar soft connection fitting 5 is connected to the tubular busbar conductive terminal block 7, and the other end is connected to the conductive component 51, and the conductive component is fixedly connected to the tubular busbar.

[0012] Specifically, the busbar is supported by the slide groove 71 and the slider 61. Since the length of the tubular busbar is usually 6 to 7 meters and the diameter is 3-5 decimeters, the bending of the tubular busbar under its own weight is very small, so that the pulling force of the tubular busbar toward the center of the busbar can be ignored. Therefore, the slider 61 will not slide in the slide groove under the weight of the tubular busbar. Therefore, during installation, the slider 61 can be located in the middle part of the slide groove 71. When the tubular busbar expands and contracts, the tubular busbar drives the slider 61 to slide in the slide groove 71 through the tubular busbar sliding support component 6, thereby adapting to the thermal expansion and contraction of the tubular busbar, and the tubular busbar soft connection hardware 5 can also adapt to the thermal expansion and contraction of the tubular busbar, thereby not affecting the diversion of the tubular busbar.

[0013] Furthermore, the detachable fixed connection between the single-pole disconnector terminal block 2 and the tubular busbar conductive terminal block 7 includes a plurality of bolt connections.

[0014] Furthermore, since the slider 61 can slide in the slide groove 71, the tubular female sliding support component 6 is made of insulating material to avoid sparks during sliding.

[0015] Furthermore, the slide groove 71 is parallel to the horizontal plane, so that the force driving the slider 61 to move left and right in the slide groove 71 is the same when thermal expansion and contraction occur.

[0016] Furthermore, the slider 61 is a cylinder, which passes through the slide groove 71 and is fixed to the tubular female sliding support component 6 by rivets at both ends of the slider.

[0017] Furthermore, the sliders 61 are two bilaterally symmetrical cylinders, and the two cylinders are respectively embedded in two sides of the slide groove 71 .
