For achieving the above object, the utility model provides a kind of waterproof mineral insulation bus duct, it is characterized in that: comprise bus duct insulating barrier main body, described bus duct insulating barrier main body is suppressed by magnesium oxide and is formed, multiple conductor is provided with in bus duct insulating barrier main body, described bus duct insulating barrier main body is outside equipped with seamless shell, and described seamless shell is aluminium shell or alloy shell or steel shell.
Further, described conductor be aluminium conductor, alloy conductor, copper-aluminum composite conductor, copper clad aluminum conductor one of them.
Further, described seamless shell is round shell.
Further, described seamless shell is square shell, and it is protruding that it is outside equipped with heat radiation.
Further, described seamless shell upper surface and lower surface are outward extended with extension.
Further, the extension of described seamless shell upper surface is provided with projection vertically upward, and the extension of described seamless shell lower surface is provided with projection vertically downward.
The beneficial effects of the utility model are: bus duct good heat dissipation of the present utility model, ampacity are large, waterproof anti-explosion, corrosion-resistant long-life, smokeless halogen-free, safety and environmental protection.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See a kind of waterproof mineral insulation bus duct shown in Fig. 1 to Fig. 6, comprise bus duct insulating barrier main body 1, described bus duct insulating barrier main body 1 is suppressed by magnesium oxide and is formed, multiple conductor 2 is provided with in bus duct insulating barrier main body 1, described bus duct insulating barrier main body 1 is outside equipped with seamless shell, and described seamless shell is aluminium shell or alloy shell or steel shell.
Bus duct described in the utility model is only made up of the seamless shell 5 outside the conductor 2 arranged in bus duct insulating barrier main body 1, bus duct insulating barrier main body 1 and bus duct insulating barrier main body 1, and structure is very simple, so assembling easily.Conductor 2 can adopt copper conductor or alloy conductor or copper-aluminum composite conductor, when bus duct insulating barrier main body 1 is produced, standby equipment carries out fastening process to magnesium oxide, this bus duct insulating barrier main body 1 is all inorganic material composition, itself can not cause fire, can not to burn or combustion-supporting, the fusing point of copper is adopted to be 1083 DEG C if seamless shell 5 adopts the fusing point of steel to be 1560 DEG C with conductor 2, the fusing point of magnesia powder is 2800 DEG C, when when fire, temperature is no more than 1000 DEG C, bus duct structure there will not be problem, the continued power time of more than 3 hours can be ensured.
Due to the bus duct insulating barrier main body 1 of this waterproof mineral insulation bus duct and the particularity of structure, can reach 300 DEG C in actual serviceability temperature, its ampacity exceedes existing bus duct.Because there is good conductive coefficient through the magnesia powder of special installation dense compaction process, transmit the identical magnitude of current, reduce to one to three cross section grades than the bus duct on existing market.
The shell adopted due to this bus duct is seamless pipe, dense compaction body between conductor 2, bus duct insulating barrier body 1 and seamless shell 5 three, thus it is made not only to have the infringement of anti-sealing, moisture, oil and some chemical substances, can also entirety be immersed in water for a long time, be a kind of waterproof anti-explosion product truly.Seamless shell 5 can adopt aluminium shell or alloy shell or steel shell.
Because this bus duct all material adopts inorganic material to make, even if under the high temperature more than 1000 DEG C, burning can not produce smog, halogen and toxic gas is the real nontoxic bus duct of Halogen.
The material adopted due to this bus duct is all inorganic material, not aging, because seamless shell inwall arranges fillet 51, fillet 51 is also arranged in the outer wall corner of corresponding bus duct insulating barrier main body 1, more be beneficial to when assembling and assemble easily, strengthen the fail safe of its assembling, prevent operator from being hurt.
Further, as shown in Figure 2, described seamless shell 5 is round shell.
Be square shell at described seamless shell 5, it is outside equipped with heat radiation protruding 3.In order to make this bus duct radiating effect better, so be outside equipped with heat radiation protruding 3 at seamless shell 5, increase its cooling surface area.
Further, described seamless shell 5 upper surface and lower surface are outward extended with extension 4.Be outward extended with extension 4 at seamless shell 5 upper surface and lower surface, further increase its cooling surface area, radiating effect is better.
Further, the extension 4 of described seamless shell 5 upper surface is provided with projection 6 vertically upward, and the extension 4 of described seamless shell 5 lower surface is provided with projection 6 vertically downward.Projection 6 is provided with vertically upward in the extension 4 of seamless shell 5 upper surface, the extension 4 of described seamless shell 5 lower surface is provided with projection 6 vertically downward, projection 6 also further increases its cooling surface area, can to be separated by time simultaneously the projection 6 of lower surface makes bus duct be placed on metope metope one segment distance, to be also convenient to heat radiation.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection range of claims.
