Moreover, the three-phase connecting copper bar is the three-phase connecting copper bar of double L bending-types, which is connected
It connects fuse three-phase output end that the upper end of copper bar is connected to be located on the left of fuse, double L bending-types three-phase connecting copper bars
The contactor three-phase input terminal that is connected of lower end be located at the right side of contactor.
The advantages of the present invention are：
1, wind-power electricity generation frequency conversion device contactor copper bar connecting structure of the invention, the common installation one of three-phase output end are vertical
Insulation frame plate, be bolted fixation between the insulation frame plate and three-phase output end, between three-phase output end between
Away from reliable guarantee can be obtained, it will not be in contact accident because of the deformation of flexible copper bar, realize the three-phase output of contactor
Terminal rationally connect with flexible copper bar, connects reliable, holding three-phase terminal spacing.
2, wind-power electricity generation frequency conversion device contactor copper bar connecting structure of the invention is installed with fuse on riser, should
Three-phase output end of fuse and the three-phase input terminal of contactor are correspondingly connected with one by one by three-phase connecting copper bar, are ensured molten
Disconnected device and contactor are stably connected with.
3, wind-power electricity generation frequency conversion device contactor copper bar connecting structure of the invention, three-phase connecting copper bar are double L bending-types
Three-phase connecting copper bar, fuse three-phase output end that the upper ends of double L bending-types three-phase connecting copper bars is connected is located at molten
On the left of disconnected device, the contactor three-phase input terminal that the lower end of double L bending-types three-phase connecting copper bars is connected is located at contactor
Right side, it is rationally distributed, it realizes space and maximally utilizes, avoid causing winding displacement to fracture because of occupied space, avoid to other structures
