Abstract
The invention discloses an aluminium-magnesium alloy housing-closed bus duct, and the bud duct comprises a housing made of aluminium-magnesium alloy, and a plurality of copper strips disposed in the housing. The directions of the copper strips are consistent with the length direction of the housing, and the copper strips are parallel to each other and arranged at intervals. Moreover, an outer wall of each copper strip is provided with an epoxy resin insulating layer in a casting manner. The bus duct can achieve large-span connection, and does not need a dedicated grounding line.
Description
Technical field
The invention belongs to engineering safety technical field, be specifically related to aluminum-magnesium alloy outer housing closed busbar slot.
Background technology
Along with emerging in large numbers of modernization project facilities and equipment, the power consumption news of all trades and professions increase, the appearance in especially numerous skyscrapers and large-sized workshop workshop, as the traditional cable of transmission pressure, can not meet the demands in big current conveying system now, the parallel connection of multiway cable uses and brings inconvenience to in-site installation construction connection.Plug type bus duct arises at the historic moment as a kind of new distribution wire, compared with traditional cable, its superiority is fully demonstrated when big current is carried, simultaneously because contact is insecure, humid environment, the factors such as erecting bed grains of sand dust, produce heating short circuit and burn phenomenon time happen occasionally.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, provides a kind of large span to connect and does not need the aluminum-magnesium alloy outer housing closed busbar slot of Special grounding wire.
For solving the problems of the technologies described above, the technical solution used in the present invention is, aluminum-magnesium alloy outer housing closed busbar slot, the housing comprising almag material and the multiple copper bars be arranged in housing, the trend of described copper bar is consistent with the length direction of housing, each copper bar is parallel to each other and interval is arranged, and the outer wall of each copper bar is all cast with epoxy resin insulating layers.
Further, be connected between this housing and copper bar by insulating part, insulating part offers the groove for engaging copper bar, and be spaced from each other between groove, the number of groove is consistent with the number of copper bar.
Further, the side of this housing is a watt barrow structure.
Further, the number of this copper bar is 4.
Present invention also offers the bus duct group that above-mentioned aluminum-magnesium alloy outer housing closed busbar slot is formed by connecting, adjacent aluminum-magnesium alloy outer housing closed busbar slot is connected by bus-bar slot connecting apparatus, and described bus-bar slot connecting apparatus top casting has epoxy resin insulating layers.
Further, this jockey is clamping plate and the buckling piece fixing with clip board engagement, spaced apartly on described clamping plate is provided with the identical clip slot in both sides, for placing the copper bar in adjacent bus duct in each clip slot.
Further, the buckling piece that these clamping plate and installing tache are combined in clamping plate top is connected by clamping plate jockey, and described clamping plate jockey is the connecting hole being opened in clamping plate top and buckling piece relevant position, and the securing member be connected with connecting hole.
Aluminum-magnesium alloy outer housing closed busbar slot tool of the present invention has the following advantages:
1. copper bar interval is arranged, and each copper bar outer wall is cast with epoxy resin insulating layers, reaches the effect of insulation, independent separately, convenient for maintaining.
2. do not need Special grounding wire between copper bar, by being tightly linked between housing, the connection grounding system safety reached between each section of aluminum-magnesium alloy outer housing closed busbar slot is firm, and is applicable to the connection grounding system of the complicated span of all size.
3. shell adopts almag material, and when mounted, in the middle of large span, suspension rod quantity can reduce 2/3, conserve space, reduces installation cost, easy to maintenance.
