Technical field
The present invention relates to a kind of grounding wire device, and conductor is grounded more particularly, to a kind of spiral compression Reed type
End terminal.
Background technology
Short-circuit grounding wire is most common security apparatus in transformer station, is led by the way that conductor end terminal is overlapped on into three-phase respectively
On body, through short-circuit line by power failure equipments three-phase shortcircuit, then guided on earthing pole by a ground wire, so as to realize to protection domain
The protection of interior workmen's safety.
Station is broadly divided into screw threads for fastening with the conductor end terminal of short-circuit grounding wire at present and two-man act compresses two kinds of modes of operation.
For spring compression type, wire clamp directly can be overlapped on conductor by operations staff, can pass through the deformation of two-man act toward next drawing
Pressure compaction conductor, upward one push away it is i.e. separable, it is easy to operate, but this connection by between spring leaf and conductor
And built on the sand, easily wire clamp is easily slid from conductor in the case where External force interference is larger, while two-man act spring is easy
Aging；For screw thread fastening type, the rotary motion of insulating bar is changed into the vertical linear motion of intermediate plate by screw thread, so as to real
Existing wire clamp is to the compression of conductor, and reliability is very high, stable connection, but this is transported the rotation of insulated operating rod by spiral lamination
Turn is changed into the vertical linear motion of folder, and this has sacrificed speed to ensure clamping force, it is necessary to which operations staff back and forth twists many circles.
It is very big due to connecing electricity folder opening, cause substantial amounts of backlash.In addition, power equipment installation site is all in eminence, so as to lead
