17 can be in I-shaped steel alloy for interface, and both ends are welded and fixed with 14 both sides of rectangular frame respectively, to by reinforcing bar
Part 17 is supported rectangular frame 14, effectively improves the ability of anti-deformation of rectangular frame 14.
In the utility model, conductor 11 is installed in the following way in shell 1, connected and fixed in shell 1 there are two pottery
Porcelain confinement block 18, ceramic confinement block 18 offer the straight slot 19 mating with conductor 11, to which 11 plugged and fixed of conductor is in logical
Within slot 19, and then realize that conductor 11 is installed on the requirement of the technology inside shell 1.
To improve the mounting stability of conductor 11, as shown in Figure 4, Figure 5,11 bolt of conductor is fixed with multigroup clamping ceramics limit
The clamping group of clamp dog 18, clamping group include two pieces of ceramic blocks to take the shape of the letter U 20, to which conductor 11 is realized by clamping group for ceramics
The anti-clamping of confinement block 18, and then the mobility that conductor 11 is slided along 1 length direction of shell is limited, effectively improve the peace of conductor 11
Fill stability.
Heat sink 13 is connect with side plate 12 in the following way in the utility model, as shown in Fig. 3, Fig. 4, Fig. 5, rectangle frame
14 both sides of frame offer the insertion elongated slot 21 being embedded in for side plate 12 along its length respectively, and 14 screw-thread fit of rectangular frame has multiple
Bolt 22 is connected, side plate 12 offers the through-hole 23 passed through for connection bolt 22；12 edge of side plate is embedded in rectangular frame 14,
And rectangular frame 14 and side plate 12 are reinforced by connecting bolt 22, so that it is guaranteed that heat sink 13 and the connection of side plate 12 are strong
Degree；Meanwhile the technique effect that side plate 12 is detachably connected with heat sink 13 is also equipped with using such connection type, to examine
When repairing inside bus duct, one heat sink 13 can be dismantled and overhauled again later, and then to be provided just inside maintenance bus duct
Profit.
