Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention is further described:
[0022] The mission of the busway is to transmit current. The current carrying capacity of the busway is determined by the rated current passing through the limit temperature rise, and the temperature rise is determined according to the heat resistance level of its insulating material. It can be seen that the temperature rise is the most critical technical parameter of the busway. At present, the insulation material of the mainstream intensive busway in the domestic market adopts B-grade polyester film with a heat resistance of 130°C. When the ambient temperature is 40°C, its allowable temperature rise is 90K.
[0023] Regarding the conductors of bus ducts, there are aluminum conductors, composite conductors, and copper conductor bus ducts on the market. More than 85% of domestic bus ducts use copper conductors, about 10% use aluminum conductors, and composite conductors are rare...

The invention provides a bus duct adapter. The bus duct adapter comprises a bus duct connecting piece and a cable connecting joint, adapters are respectively arranged at the starting end and the ending end of a fault section; the bus duct connecting pieces are used for being connected with bus ducts which does not break down before the starting end and after the ending end, and the adapters of thestarting end and the ending end are connected together through a multi-core cable according to the cable connecting joint. The invention also provides a maintenance method of the bus duct. The maintenance method comprises the following steps: 1) determining a damaged bus duct interval; 2) respectively arranging one bus duct adapter at each of the interval, the starting position and the ending position; (3) connecting the bus duct connecting pieces of the two bus duct adapters with undamaged bus ducts, and connecting the cable connection joints of the two bus duct adapters by using the multi-core cable, and (4) repurchasing and replacing the bus ducts in the fault section according to the model.
Description
technical field [0001] The invention relates to electric equipment, in particular to a bus duct. Background technique [0002] With the continuous optimization of urban distribution networks and the increasing demand for electricity from users, more and more bus ducts have replaced the original single-core and multi-core cables. The bus duct is a bus system composed of metal plates as protective shells, conductive bars, insulating materials and related accessories. It can be made into a plug-in closed busbar with a plug-in junction box at intervals, or a feed-type closed busbar without a junction box in the middle. The busway has the advantages of convenient tap feed, large transmission current, low energy consumption, voltage drop, and good dynamic and thermal stability. The busway is suitable for the AC power supply with a rated voltage below 660V and a frequency of 50Hz. It can work for a long time under the rated current and 110% of the rated voltage. The insulation r...
