Summary of the invention
In order to remedy not antidetonation of above-mentioned bus, when vibration is arranged, come off easily and cause the defective of line short, the present invention to propose a kind of antidetonation bus.
Its technical scheme does; A kind of antidetonation bus comprises electric conductor, comprises electric conductor, is wrapped in the insulator in the electric conductor outside, the antidetonation assembly that is secured together with insulator; Said electric conductor constitutes by outer conducting layer is mutually nested with inner conducting layer, fills insulating barrier between the inside and outside conductive layer.In the present technique scheme, bus utilizes antidetonation assembly damping vibration to the influence that bus brings, and has offset the influence of most of vibration to bus, has prevented that bus from coming off because of vibration or the phenomenon of short circuit, has improved the fail safe and the reliability of bus.
Said antidetonation assembly adopts the spring anti-seismic structure, comprise the outside base plate, and the top board that is fixed together of insulator and be connected top board and base plate between spring.Adopt spring structure, simple, the present technology maturation of spring is stable, and cheap relatively, is convenient to large-scale promotion.
Be enclosed with many electric conductors in the said insulator, and mutually insulated is airtight between the adjacent conductive body.Electric conductor in insulator can be many, forms four line three-phases, five line three-phases or other supply power mode, is convenient to be connected with extraneous power utilization environment.
On bus, also be connected with the connector that supplies extraneous lead to connect, said connector passes insulator and connects together with electric conductor.Connector is bus is connected power supply with extraneous lead a part, adopts special-purpose connector to be fixedly connected on the bus, and it is stable to have guaranteed that bus is externally supplied power.
On insulator, also be fixed with and the extraneous geometrical clamp that is connected.Adopt geometrical clamp that bus is fixed to extraneous wall or other civilian posts, be convenient to the installation of bus, geometrical clamp can increase or reduce convenient construction as required simultaneously.
On bus, also be connected with overload protective device, overload protective device passes insulating barrier and connector links together.Overload protective device is monitored the size of current that connector distributes constantly, and protection bus and connector can not damage because of the situation of overload.
Said inner conducting layer and/or outer conducting layer adopt copper cash or aluminium alloy wire to twine hinged forming.Adopt copper cash or aluminum steel to twine inner conducting layer and/or the outer conducting layer that is hinged to; Make the current-carrying part of bus have elasticity, can be not impaired because of slight vibration, the vibration that cooperates the buffering bus to receive with the antidetonation assembly; Make bus more difficult damage when being vibrated; The relative busbar processing of copper cash or aluminum steel simultaneously is convenient, is convenient to adjust the diameter and the pay(useful) load of bus electric conductor, makes things convenient for the bus production of different model.
Said insulator and insulating barrier adopt polyolefin to extrude and form.The mode that adopts polyolefin to extrude wraps inner conducting layer/outer conducting layer, and procedure of processing is convenient, convenient insulated enclosure to electric conductor.
Antidetonation assembly of the present invention can well be alleviated vibration and bring infringement to bus when having vibrations to take place, prevent bus come off guarantee to supply power normal; Electric conductor is hinged lead, and the metallic conduction of specific rigidity row has better anti seismic efficiency, and lead can connect as requested whenever and wherever possible, does not receive effect length; Adopt fire-retardant, the low cigarette polyolefin of insulation to make insulation sheath, safety and environmental protection; Adopt inside and outside two-conductor, increase the ampacity of bus.
