Abstract
The utility model discloses an air insulation bus duct including a bus dust casing, an insulating support, busbars, jump rings, installing plates, and fixing bolts. The bus duct casing is composed of cover plates and side plates, protruding edges correspondingly clamped with the grooves in the upper and lower ends of the side plates are arranged at the upper and lower ends of the installing plates, the insulating support and the installing plates are connected through the fixing bolts, the jump rings are connected at the external side of the installing plates via the fixing bolts, the end parts of the cover plates are provided with protruding edges which are inserted into the gaps formed by the grooves in the end of the side plates and the free ends of the jump rings, and chuck the cover plates through the spring action of the jump rings. The bus duct provided realizes the bolt-free connection of the bus duct casing, and is less in component, easy to assemble, and beautiful in appearance; furthermore, the protective grade of the casing is improved.
Description
Technical field
The utility model relates to a kind of bus duct, is specifically related to a kind of air insulation type bus duct.
Background technology
Bus duct is to be protecting sheathing by metallic plate, and the bus-bar system that busbar, insulating material and related accessories are formed can be divided into intensity, air insulation type, solid insulation type etc. according to its structure and purposes.
Along with emerging in large numbers of modernization project facility and equipment; The power consumption of all trades and professions is fast to be increased; The appearance in especially numerous skyscrapers and large-sized workshop workshop can not meet the demands in the now big electric current conveying system of traditional cable as transmission pressure, and the parallel connection of multiway cable is used to on-the-spot installation connection and brought inconvenience; Compare with traditional cable, bus duct demonstrates fully its superiority when big electric current is carried.
At present; Common on the market air insulation type bus duct comes with some shortcomings: the connected mode between bus duct side plate and cover plate and the insulating support is employed in the connected mode of punching bolt on the side plate mostly; Be divided into screw side plate outside with screw inner two kinds of side plate, screw hangs down the scope of application that influences bus duct in the outside shell protection grade of side plate, and influences the attractive in appearance of shell; Screw is the easy modification of sheet material when side plate machined complex process and punching; Reduce the intensity of shell, easy modification in assembling transportation installation process, complex manufacturing technology; Cost is high, and these shortcomings are affecting the result of use of air insulation bus duct in the low-voltage distribution field.
The utility model content
The utility model provides a kind of intensity height, good, the simple novel air isolated bus of the process and assemble groove of thermal diffusivity.
The technical scheme of the utility model: a kind of air insulation bus duct; Comprise bus duct shell, insulating support, busbar, jump ring, mounting panel, set bolt; Said bus duct shell is made up of cover plate, side plate, the chimb of the corresponding clamping of groove of said mounting panel upper and lower end parts setting and side plate upper and lower end parts; Connect through set bolt between said insulating support and the mounting panel; Said jump ring is connected in the mounting panel outside through set bolt; Said patch ends is provided with chimb, and the gap that the groove of insertion side end and the free end of jump ring form is through the elastic force effect chucking cover plate of jump ring.
Said side plate outer setting reinforcement.
The quantity of said reinforcement is the 6-14 bar.
Said busbar is the copper aluminium composite bus, and the busbar skin is provided with insulating barrier.
Said cover plate, side plate are the manufacturing of almag section bar.
The technique effect of the utility model: 1, the utility model is provided with chimb in patch ends, and side end is provided with groove, fastening jump ring on the connecting plate; The cover plate chimb inserts the gap that forms between jump ring and the side plate groove, and elastic force and side plate through jump ring connect as one the connection of realization bus duct shell non-bolt; Parts are few; Be easy to assembling, good looking appearance has improved the shell protection grade; 2, the bus duct shell adopts the almag material, and the reinforcement of some is set on the side plate, has also increased the radiating effect of shell when improving the bulk strength of shell; 3, busbar adopts the copper aluminium composite bus as current, replaces traditional copper busbar and aluminium busbar, and outer is that copper, internal layer are aluminium, and performance parameter is basically near copper conductor, and is in light weight, cost is low, and energy-saving effect is remarkable.

Fig. 3 is the utility model cover plate, side plate, flat spring, insulating support syndeton partial schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Like Fig. 1, Fig. 2, shown in Figure 3; The air insulation bus duct; Comprise bus duct shell, insulating support 3, busbar 4, jump ring 6, mounting panel 7, set bolt 8; Said bus duct shell is made up of cover plate 1, side plate 2, the chimb of the corresponding clamping of the groove of said mounting panel 7 upper and lower end parts settings and side plate 2 upper and lower end parts; Connect through set bolt 8 between said insulating support 3 and the mounting panel 7; Said jump ring 6 is connected in mounting panel 7 outsides through set bolt 8; Said cover plate 1 end is provided with chimb, and the gap that the groove of insertion side plate 2 ends and the free end of jump ring 6 form is through the elastic force effect chucking cover plate 1 of jump ring 6.
Said side plate 2 outer setting reinforcements 5, the effect of playing heat radiation and reinforcing.
The quantity of said reinforcement 5 is the 6-14 bar.
Said busbar 4 is the copper aluminium composite bus, and the busbar skin is provided with insulating barrier 9, and the material of insulating barrier 8 is the thermoplastic sleeve pipe.
Said cover plate 1, side plate 2 are by almag sheet material clod wash machine-shaping, and length can reach about 6 meters, and convenient the installation reduced the use of connector in the installation process, thereby practiced thrift cost.
