When the bus duct breaks down, a worker firstly removes the bolts 22, then moves the fixed plate 1 in a specified direction, and releases the locking of the connecting mechanism on the fixed plate 1 and the side plate 2, so that the fixed plate 1 on the bus duct is removed, the interior of the bus duct is exposed, and the worker can conveniently overhaul and maintain the broken bus duct;
Meanwhile, when the bus duct is removed and reinstalled, the worker aligns the entrance end of the entrance slot 141 on the fixing plate 1 with the connection block 21 on the side plate 2, then, the worker pushes the fixing plate 1 to move toward the conductor 4, after the connection block 21 reaches the end of the entrance slot 141 far from the fixing plate 1, the fixing plate 1 stops moving, at this time, the connection block 21 aligns with the entrance of the locking slot 15 connected to the entrance slot 141, then, the worker pushes the fixing plate 1 along the length direction of the bus duct, so that the connection block 21 slides into the locking slot 15, thereby fixing the fixing plate 1 with respect to the side plate 2, and at the same time, the worker installs the bolt 22 on the side plate 2, so that the bolt 22 releases and extrudes the contact edge 11;
meanwhile, the fixing plates 1 and the side plates 2 are connected and fixed through the connecting mechanism, so that the structure of the bus duct is relatively simple, a plurality of bolts 22 are not needed to be used for connecting the bus duct, the bus duct is convenient to detach, meanwhile, two fixing plates 1 and the side plates 2 on the bus duct are independently connected and fixed, any fixing plate 1 can be detached to open the bus duct, and after one fixing plate 1 is detached, other structures of the bus duct can still be stably connected;
Meanwhile, the inner fins 12 and the outer fins 13 are arranged on the fixed plate 1, so that heat generated in the working process of the bus duct is more easily transferred and dissipated, and meanwhile, when the bus duct breaks down, workers can conveniently disassemble, assemble and replace a single damaged insulating plate 3 or a conductor 4 by matching with a plurality of groups of insulating plates 3;
After the locking groove 15 is formed in the contact edge 11 so that the bolt 22 is fixed to the side plate 2, the bolt 22 is also inserted into the locking groove 15 so that the bolt 22 and the locking groove 15 are locked with each other;
Meanwhile, by arranging the locking groove 15 on the contact edge 11, when the fixed plate 1 is connected to the side plate 2, the worker can conveniently judge the completion degree of the installation of the fixed plate 1 through the corresponding relation between the locking groove 15 and the installation hole of the bolt 22 on the side plate 2, and the fixed plate 1 is ensured to be installed in place relative to the side plate 2;
during the process of installing the bolts 22 on the side plates 2, the tapered side surfaces of the pressing blocks 23 can contact and press the locking grooves 15, so that the fixed plate 1 tends to move towards the electric conductor 4, and the fixed plate 1 and the insulating plate 3 are ensured to press the electric conductor 4;
the elastic layers 33 are arranged in the positioning grooves 32 and the mounting grooves 31, so that the surface of the electric conductor 4 or the inner fin 12 is prevented from being scratched and scratched during mounting;
meanwhile, when the bus duct works normally, the conductor 4 in the bus duct generates heat, so that the heated temperature of the deformation sheet 331 is increased, after the temperature of the deformation sheet 331 is increased, the deformation sheet 331 made of the bimetallic strip deforms, so that the deformed deformation sheet 331 extrudes the conductor 4 or the inner fin 12, and the installation stability of the inner fin 12 and the conductor 4 is improved;
by arranging the partition plates 5 between the conductors 4, the fireproof and flame-retardant performance of the bus duct is improved;
Meanwhile, after the insulating groove is arranged on the fixed plate 1, a worker firstly installs the partition plate 5 on the insulating plate 3 through interference fit between the insert block 51 and the slot 34, so that the partition plate 5 forms a supporting structure on two sides of the mounting groove 31, the worker is convenient to install the conductor 4 in the mounting groove 31, and meanwhile, the supporting structure formed by the partition plate 5 limits and supports the conductor 4;
The elastic contact layer is arranged on the partition board 5, so that when the partition board 5 supports the electric conductors 4, gaps between the partition board 5 and the electric conductors 4 are also closed, the effect of separating spaces between adjacent electric conductors 4 by the partition board 5 is improved, meanwhile, the contact layer is extruded and deformed, the electric conductors 4 are convenient to install, and damage to the insulating layer on the surface of the electric conductors 4 due to the fact that burrs exist or are hard on the surface of the partition board 5 is avoided;
by roughening the surface of the contact layer, the friction between the contact layer and the electrical conductor 4 is relatively high, so that after the electrical conductor 4 is mounted on the insulating plate 3, the electrical conductor 4 is relatively fixed by the supporting structure formed by the spacers 5;
when the insulating plate 3 is installed, the double faced adhesive tape on the insulating plate 3 can be adhered to the surface of the fixed plate 1, so that the insulating plate 3 and the fixed plate 1 are preliminarily connected, and the insulating plate 3 is prevented from falling off or moving along the length direction of the inner fins 12.
