Fig. 2 is a schematic structural diagram of a copper busbar tee box on a bridge frame 8 according to an embodiment of the invention. Fig. 3 is a schematic cross-sectional view of a copper busbar tee box on a bridge frame 8 according to an embodiment of the invention.

As shown in fig. 1 to 3, a copper bar tee box on a bridge frame according to a preferred embodiment of the present invention includes: the casing subassembly and T connect the case subassembly. The shell component comprises a box body 1 and a box door 2, wherein the box door 2 is movably connected with the front end of the box body 1, and a back plate 3 of the box body 1 is formed by splicing a blind sheet 4 and a perforated sheet 5. T connects the case subassembly to set up in box 1, and T connects the case subassembly to include female insulating fixing base 6 and the tinned copper bar 7 of arranging, and female insulating fixing base 6 that arranges sets up on backplate 3. Wherein the housing assembly is fixed to the bridge 8 by means of a connection 19. Wherein, the tinned copper bar 7 is 90 degrees with the backboard 3 and the box door 2. Wherein, the box door 2 is provided with a transparent observation window 9. Wherein, install rubber seal on the trompil piece 5, the cable on the crane span structure 8 passes the rubber seal of trompil piece 5, and lug 16 is 90 degrees with tin-plated copper bar 7.

In one embodiment of the invention, the tail of the lug 16 has a temperature changing jacket 17. Mounting holes 10 are respectively formed in four corners of the back plate 3, and the back plate 3 can be fixed on the wall surface through bolts, so that the mounting function of the copper bar T connection box is expanded.

In one embodiment of the invention, the box 1 is fixed to the bridge 8 by means of a connecting element 19. The blind sheet 4 is provided with a bus bar classification identification label 11. The door 2 is movably connected with the front end of the box body 1 through a door shaft hinge 12.

The cable passes the rubber seal who splices trompil piece 5 after, and lug 16 is 90 degrees with the copper bar, and the screw rod of lug 16 crimping bolt, nut operation and clearance gauge detect very conveniently. The cable is arranged very clearly, and the laminating degree of lug 16 and copper bar is clear and visible. The wall surface mounting holes 10 reserved on the back plate 3 of the box body 1 can also be mounted on the wall surface, and the four connecting pieces 19 of the copper bar T connecting box and the bridge frame 8 can also be mounted on the front surface and the back surface of the bridge frame 8 (holes are required at the positions of the cable passing positions). The box door 2 is provided with the transparent observation window 9, so that the working state of each branch in the box can be visually observed, and the tail part of the lug 16 uses the 70-degree variable-temperature sleeve, thereby being greatly convenient for finding hidden dangers before dangers occur in the maintenance and inspection work.

The process of the copper bar T-shaped connecting box on the bridge frame in use is as follows:

1. removing the blind sheet 4 and the perforated sheet 5 at the back of the T-shaped connecting box;

2. the copper bar T-shaped connecting box and the four connecting pieces 19 of the bridge 8 are respectively arranged at the upper and lower four corners of the T-shaped connecting box (namely the four corners of the backboard 3), and can be adjusted to corresponding positions along with the width of the bridge 8, and holes are turned and fixed by bolts (the box body 1 and the bridge 8 are connected with a double-color grounding wire);

3. the blind plate 4 and the perforated plate 5 are installed from top to bottom, and after a gap between the blind plate 4 and the perforated plate 5 which are parallel to each other and the tinned copper bar 7 is placed in the gap, the blind plate and the perforated plate are rotated by 90 degrees to be aligned with a bolt hole on the box body 1 and are fixed by flat head self-tapping;

4. simultaneously, a small hole is punched on a protective film in the middle of the rubber sealing protective coil 18 by using a sharp tool such as a screwdriver, a cable selection copper bar mark with the same phase sequence penetrates through the rubber sealing protective coil 18 on the perforated sheet 5, then a temperature-changing sheath 17 is pre-sleeved, cable peeling, lug 16 pressing and lug 16 is pressed and fastened;

5. the door 2 is closed.

In a word, the copper bar T-shaped connecting box on the bridge frame is simple and reasonable in structure, the copper bars, the box body back plate and the door are in a 90-degree state, gaps among the copper bars are relatively large, and installation and operation are easy. The cable passes through the rubber seal ring of back concatenation trompil piece, and the lug is 90 degrees with the copper bar, and the screw rod of lug crimping bolt, nut operation are very convenient. The cable is arranged very clearly, and the laminating degree of lug and copper bar is clear visible. The box door is provided with the transparent observation window, so that the working state of each branch in the box can be visually observed, and the tail part of the wire lug uses the temperature-variable sleeve, thereby greatly facilitating the timely discovery of hidden dangers before dangers occur in the maintenance and inspection work.
