The trailing flank of first collets is fixed on by its screw being engaged to be horizontally arranged on the installing plate being vertically arranged；
Second screw of the middle part of second collets provided with two horizontal insertions along the longitudinal direction, passes through what is be matched therewith
Screw will be fixed on the leading flank of the first collets on rear side of the second collets；And first collets and the second collets it is upper
Surface forms a plane；
The strip copper installation hole of three up/down perforations is interval with the plane, and the length direction in copper installation hole is
Fore-and-aft direction, one end is on the first collets, and the other end is on the second collets；It is located at first in the both sides in copper installation hole exhausted
The part of edge block is respectively equipped with a deep gouge, and two deep gouges are in the same horizontal line；
Some insulated trench and up/down perforation parallel with copper installation hole are provided between adjacent copper installation hole
Leaking hole.
The circular hole of a up/down perforation is respectively equipped with four angles in copper installation hole.
Three copper installation holes and two the second screws are arranged at intervals.
Compared with prior art, the fixed structure of three-phase copper bar that the present invention is provided by the deep gouge on copper installation hole and
The flat head screw on copper bar coordinated with it holds copper bar, reduces the live load of operating personnel during copper installation, letter
The fixed form of copper bar is changed；The structure of first collets and the second collets can not only be realized to be consolidated to the machinery of three-phase copper bar
It is fixed, moreover it is possible to ensure the reliable electric creep age distance between three-phase copper bar.

Fig. 2 is the overall structure diagram of the first collets and the second collets.
Fig. 3 is the scheme of installation of the fixed structure of three-phase copper bar.
Fig. 4 is the schematic side view of three-phase copper bar.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described further, but following embodiments are absolutely not to this hair
It is bright to have any limitation.
As Figure 1-3, the fixed structure of the three-phase copper bar includes：Main body is tabular and horizontally disposed first collets
1 and second collets 2；
Wherein, the two ends of the first collets 1 are respectively equipped with the first screw 7 of a horizontal insertion along the longitudinal direction, pass through
The trailing flank of first collets 1 is fixed on and is horizontally arranged on the installing plate 5 being vertically arranged by the screw being matched therewith；
Second screw 4 of the middle part of second collets 2 provided with two horizontal insertions along the longitudinal direction, by being matched therewith
Screw the trailing flank of the second collets 2 is fixed on the leading flank of the first collets 1；And first collets 1 and second it is exhausted
The upper surface of edge block 2 forms a plane 15；
The strip copper installation hole 13 of three up/down perforations, the length in copper installation hole 13 are interval with plane 15
Direction is fore-and-aft direction, and one end is on the first collets 1, and the other end is on the second collets 2；Both sides in copper installation hole 13
A deep gouge 9 is respectively equipped with positioned at the part of the first collets 1, two deep gouges 9 are in the same horizontal line；
Depression forms some parallel with copper installation hole 13 exhausted in plane 15 between adjacent copper installation hole 13
Edge groove 8, the middle part of insulated trench 8 forms the leaking hole 11 of some up/down perforations.Insulated trench 8 can be increased between three-phase copper bar
Creep age distance, leaking hole 11 passes out under gravity after can guarantee that larger water droplet condensation, prevents at two absolutely
Washmarking is left on edge block, causes to climb electrical insulation capability disappearance, it is ensured that overall high insulating property.
The circular hole 12 of a up/down perforation is respectively equipped with four angles in copper installation hole 13, insertion copper installation is can guarantee that
Four angles of the copper bar cross section in hole 13 can preferably fix copper bar with the first collets 1 and the good contact of the second collets 2；
Also it can prevent copper bar and two collets from producing interference.
Three copper installation holes 13 and two the second screws 4 are arranged at intervals.
Now the installation method of the fixed structure of the three-phase copper bar of the present invention is described below：
As shown in figure 4, first opening the spiral shell that a level runs through at the middle part of A phases copper bar 3, B phases copper bar 10 and C phases copper bar 14
Hole, flat head screw 6 is squeezed into shown screw, and the two ends of flat head screw 6 is exposed independent from the certain size in surface of copper bar, because
The two ends of this flat head screw 6 can be stuck in the deep gouge 9 of the both sides of copper installation hole 13, so that A phases copper bar 3, B phases copper bar 10 and C
Phase copper bar 14 can be fixedly secured on copper installation hole 13.
Then, the trailing flank of the first collets 1 is fixed on installing plate 5 using the first screw 7 and the screw coordinated with it
On, the part copper bar that the side of A phases copper bar 3, B phases copper bar 10 and C phases copper bar 14 then is separately fixed at into the first collets 1 is pacified
Fill on hole 13, be finally horizontally inserted the second collets 2 from the opposite side of A phases copper bar 3, B phases copper bar 10 and C phases copper bar 14, make three
Phase copper bar is all inserted in complete copper installation hole 13 respectively, and is fixed on the trailing flank of the second collets 2 with the second screw 4
On leading flank on first collets 1.
Therefore, the fixed structure of three-phase copper bar of the invention coordinates by the deep gouge 9 on copper installation hole 13 and with it
Flat head screw 6 on copper bar holds copper bar, reduces the live load of operating personnel during copper installation, simplifies copper bar
Fixed form；The structure of first collets 1 and the second collets 2 can not only be realized to be mechanically fixed to three-phase copper bar, moreover it is possible to protected
Demonstrate,prove the reliable electric creep age distance between three-phase copper bar.
