Technical field
The present invention relates to bus duct technical field, more particularly to a kind of high efficiency and heat radiation bus duct for big data.
Background technology
With the fast development in city, building power load increases with the increase of skyscraper, traditional electric power
Conveying equipment starts not adapting to the demand in market slowly, and bus duct starts to replace the status of electric wire commercially gradually.
In recent years, bus duct turns on power Transmission main line in main flow, such as the important engineering such as hotel, airport, subway, and bus duct accounts for
Very big component, therefore, the security performance and stability of bus duct are vital.But bus duct is there is also defect,
Especially it is embodied on the heat dispersion of bus duct, it is female because generally higher heat occurs in the boundling arrangement between bus duct
The heat dissipation problem of wire casing turns into the factor of important consideration when research staff researches and develops product.Especially for mesohigh bus duct
Speech, because such bus duct is mainly the electrical power mains line of mesohigh, so heat dispersion, security performance and can effectively drop
Low electric energy consume is vital, if such high voltage bus groove does not possess necessary heat dispersion, once in bus duct
High temperature caused by connection busbar can not disperse in time, just probably bring the hidden danger of fire safety.
The content of the invention
