Description
Technical field
The utility model relates to a kind of ground connection bars, are grounded bar more particularly, to a kind of multi-angle.
Background technique
In substation, ground line is one of the tool of manpower assembly and disassembly, and installation site is mainly aluminum bronze row and the difference of plane
The cable of angle.If being mounted in aluminum bronze row, that requires the ground connection bar using flat mouth；If being mounted to high voltage power transmission
Ground line on cable then generally uses the ground connection bar of packet mouth, to prevent degree of tightening from not enough slipping.Furthermore either where
Kind of installation site, can all there is the situation of position height and angle multiplicity, such as high voltage electric transmission cable, have horizontal plane arrangement, have 45
Spend it is that angle stretches, there are also completely vertical, to overcome these situations, previous way otherwise be climb very it is high go to overcome or
It is in addition to purchase the ground connection bar of 90 degree of bending heads to install.If it is in addition purchasing, that increases expense investment, but also
Occupy place；If it is personnel climb it is higher go to install, then again there are the security risk that personnel's eminence is fallen, operate be also very
It is difficult.
Because these are insufficient, some substations can purchase flat mouth or the ground connection bar of packet mouth respectively accounts for half, also there is one
A little substations have the ground connection bar of 90 degree of bending heads, and amount is few, can be climbed after all by personnel to overcome.Generally speaking, no
Convenient, impracticable, not safe enough problem there are still.
Utility model content
