Description

A kind of novel energy-conserving high-cooling property bus duct

Technical field

The utility model relates to a kind of bus duct, belongs to the technical field of transmission facility.

Background technology

Low voltage bus bar groove is the staple product that electric power transfer is responsible in low pressure power transmission and distribution field, in large electric current and industrial and mineral, factories and miness place, have cable incomparable a bit.Most important performance index are exactly " temperature rise " in the bus duct, the temperature rise of bus duct directly has influence on the running quality of whole electrical power trans mission/distribution system, the operating temperature of the higher proof conducting copper of the temperature rise of bus duct is higher, and higher its conductive capability of the operating temperature of copper bar is poorer, and the operating temperature of bus duct and conductive capability form vicious circle like this.A lot of places cause the busbar temperature rise too high because the bus duct thermal diffusivity is bad, cause whole piece bus duct scaling loss, even a large amount of power consumption equipment scaling loss, cause serious economic loss, and potential safety hazard.

Conventional bus duct structure is that busbar is placed in the bus duct shell, separate by the insulation spacer block between busbar and the shell, the busbar heat radiation is conducted heat to space outerpace by the mutual heat conduction of material fully, this kind mode heat dispersion extreme difference, as during summer high temperature because ambient temperature is high, so that the bus duct heat radiation is poorer, cause bus duct to burn phenomenon and often occur, be the problem that many producers relatively have a headache.Conventional solution is to strengthen connecing bus duct busbar cross section, and the method has been wasted material has increased cost.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of novel energy-conserving high-cooling property bus duct for the deficiencies in the prior art, and this bus duct heat dispersion is strong, has solved because the bad problem that causes the bus groove transmission system to be burnt of bus duct heat radiation; And simple in structure.

In order to solve the problems of the technologies described above, a kind of novel energy-conserving high-cooling property of the utility model bus duct, comprise shell, some busbars, described busbar is installed in the described shell, wherein, described busbar outer wrapping insulation film, close-packed arrays between described busbar and the busbar fits tightly between busbar and the outer casing inner wall.

Above-mentioned a kind of novel energy-conserving high-cooling property bus duct, wherein, the cover plate of described shell and the side plate of the shell outside are fixed with aluminium alloy heat radiation shell fragment.

Above-mentioned a kind of novel energy-conserving high-cooling property bus duct, wherein, described aluminium alloy heat radiation shell fragment is the waveform member.

The beneficial effects of the utility model:

First, high-cooling property bus duct of the present utility model is by fitting tightly busbar and shell, and in bus duct shell welding aluminium alloy heat radiation shell fragment, further improved the bus duct thermal diffusivity, eliminated because ambient temperature is too high, bus duct short period overload operation causes the problem of bus duct steep temperature rise; The second, realized that bus duct busbar cross section can reduce than common bus duct cross section, saved material, improved properties of product.

Simultaneously, about energy-conservation aspect, CQC authentication techniques standard is about pointing out in the energy-conservation authentication techniques standard of bus duct, energy-saving bus slot and common bus duct are at copper bar, specification, all technical parameters of current class all under the same case, the ratio of electric energy loss is for energy-conservation more than or equal to 2%, the energy-saving bus slot common bus duct that compares the most important thing is to improve heat dispersion so, reduces the copper bar temperature, thereby promotes the copper bar ampacity.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

A kind of novel energy-conserving high-cooling property of the utility model bus duct, comprise shell 1, some busbars 2, described busbar 2 is installed in the described shell 1, each described busbar 2 outer wrapping insulation film, close-packed arrays between described busbar 2 and the busbar 2, fit tightly between busbar 2 and shell 1 inwall, the busbar 2 of wrap insulate film is placed in the aluminium alloy extrusions shell 1 closely, close-packed arrays between busbar 2 and the busbar 2, busbar 2 fits tightly with the cover plate of shell, the side plate of shell, has improved the busbar heat dispersion; Described shell 1 is comprised of cover plate and side plate, and described cover plate and described side plate are fixed into one, and the cover plate of described shell 1 and the side plate of the shell outside are fixed with aluminium alloy heat radiation shell fragment 3 by welding or other modes.Described aluminium alloy heat radiation shell fragment 3 is the waveform member, planar section at aluminium alloy heat radiation shell fragment 3 protrudes the plane with local punching press again, like this, and increasing heat radiation area as much as possible, further increase the contact-making surface of bus duct outer surface and surrounding environment, the radiating effect when having improved the bus duct operation.
