As a further aspect of the present invention: the highest position of the middle part of the second arc-shaped bulge is lower than the notch of the groove, and the two through holes 32 are connected with the two ends of the second arc-shaped bulge.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses a set up first mounting groove, fin etc. because intensive bus duct itself carries out the passive heat dissipation through the casing with the row zonulae occludens that leads, and the fin that a plurality of parallel equidistance distribute has increased the surface area of casing, makes the heat-sinking capability of bus duct strengthen greatly.

2. The utility model discloses a set up first arc arch, recess, second arc arch, through-hole etc. when the drop of water condensed or the top drips at the bus duct outer wall and etc. cause bus duct shell to gather water, first arc arch can be effectual with the leading-in recess of water in, through the leading-in through-hole discharge of water of second arc arch, guaranteed the waterproof performance of bus duct, avoided the condition such as alternate insulation decline and short circuit to take place.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, in the embodiment of the present invention, an aluminum alloy shell intensive insulation bus duct, including casing 1, casing 1's inside is run through and is provided with electrically conductive row 4, casing 1's top and bottom symmetry are provided with first mounting groove 11, two lateral wall symmetries of casing 1 are provided with second mounting groove 12, the inner wall length limit direction of first mounting groove 11 is provided with first arc arch 2, first arc arch 2's top is provided with a plurality of fins 21, first mounting groove 11's inner wall is close to both ends department symmetry and has seted up two recesses 3, two recesses 3's center department is provided with second arc arch 31, recess 3's inner wall is close to both ends department and has seted up through-hole 32.
