Background
In the field of power distribution, the bus duct is used as equipment for transmitting and distributing power, and has the advantages of large current-carrying capacity, convenience in installation, safety, reliability, convenience in power distribution and the like. In recent years, as people have more and more demand for electricity, bus ducts are gradually used in large power supply equipment.
However, as the intensive bus duct has some disadvantages in current transmission, for example, because the current transmission is large, at the connector position of each section of the joint of the intensive bus duct, because the gap between the conductive bus bar and the conductive connecting bar of the connector is unavoidable, the internal heating degree of the connector is generally higher than that of the intensive bus duct main body, and the insulation board at the joint of the traditional intensive bus duct product is not heat-conducting and the cover plate is not in contact with the joint, the heat resistance is too large, so that the heat generated at the joint cannot be dissipated, the internal temperature of the connector position is higher than that of other parts of the intensive bus duct, and potential safety hazards exist.
Although the 'bus duct connector with heat conducting plates' disclosed in the chinese patent application No. 201720400649.1 can solve the problem of too high temperature at the joint part of the bus duct, the heat conducting plates are added, so once the bolts are loosened, the thermal resistance is larger. Although the 'bus duct joint connecting assembly with the heat dissipation function' disclosed in the chinese patent application No. 201921376840.2 solves the heat dissipation problem of the joint cover plate, the heat dissipation plate makes the joint position higher than the main structure body, which is not beneficial to installation.
