When separating primary equipment due to lead-in wire, it likely carries induced electricity and residual charge, therefore, after lead-in wire is removed, first with binding clip, clamps lead-in wire, by ground wire, is discharged induced electricity and is participated in electric charge.During use, by binding strap, one end of the first insulating bar is fixed on primary equipment, pigtail splice is fixedly connected with by binding clip.While removing lead-in wire, the second insulating bar is turned to the position near primary equipment centered by universal joint, thereby geometrical clamp is guided near staff, staff removes after lead-in wire, can directly lead-in wire be fixed with binding clip; And then adjust the second insulating bar, and driven binding clip and lead-in wire away from primary equipment, lead-in wire and primary equipment are kept apart, then carry out high-potting work; After experiment work finishes, again adjust the second insulating bar, binding clip and lead-in wire are pulled near staff, be convenient to staff and recover lead-in wire.
Because insulating bar is rigid material, therefore it can stablize the distance of controlling lead-in wire and primary equipment, and can not be subject to External Force Acting and wave, with the binding clip of ground wire, can directly discharge its induced electricity and residual charge when the connecting lead wire, avoid its induced electricity, residual charge to cause high-tension electricity to hurt sb.'s feelings, greatly improved the security of construction.Meanwhile, due to the rotatable adjusting lead-in wire of insulating bar and the distance of primary equipment, therefore for staff, can be with regard near operation, therefore simple, convenient.
The utility model can further be specially:
Also include geometrical clamp, it is plugged between the second insulating bar and binding clip.
Consider that binding clip will draw ground wire, anchor leg again, may produce the fixedly problem of aspect that goes between, therefore introduce geometrical clamp, when lead-in wire is separated primary equipment, first with binding clip, clamp lead-in wire, by ground wire, discharge induced electricity and participate in electric charge, and then be fixedly connected with lead-in wire by geometrical clamp, to guarantee safe construction.
Geometrical clamp includes upper clamping piece, lower clamping piece and set bolt, the two has included semi arch member, one end of semi arch member has the yi word pattern member of extension, the other end is connected with spool cover, the semi arch member of upper clamping piece and lower clamping piece merges conglobate folder chamber, and the trepanning of the spool of upper clamping piece and lower clamping piece cover overlaps, wherein be installed with axle, form jointed shaft part, the yi word pattern member of upper clamping piece and lower clamping piece is superimposed, and being vertically arranged with screw, set bolt and this screw are adaptive, and stubborn being connected on wherein; On the upper clamping piece of geometrical clamp, be provided with abutment ring, this abutment ring is fixedly connected with the other end of the second insulating bar, is fixedly connected with by stay cord with binding clip simultaneously.
During use, turn on set bolt, (upper clamping piece be take jointed shaft part and relative to lower clamping piece, is rotated as fulcrum to open upper clamping piece and lower clamping piece, and away from lower clamping piece), lead-in wire is placed in circular folder chamber, closed upper clamping piece and lower clamping piece, until yi word pattern member is superimposed, are tightened set bolt, complete being fixedly connected with lead-in wire.The program of decontroling lead-in wire is contrary with above-mentioned fixing program.
Described binding strap is a kind of belt.
Belt has good colligation fixed characteristic, is difficult for slippage.
In sum, the utility model provides pigtail splice solid ground instrument for a kind of high-potting, the two insulating bars of the adjustable control lead-in wire adopting and the rigidity of primary equipment distance, therefore it can stablize the distance of controlling lead-in wire and primary equipment, and can not be subject to External Force Acting and wave, employing, with the binding clip connecting lead wire of ground wire, has avoided its induced electricity, residual charge to cause high-tension electricity to hurt sb.'s feelings, and has higher security.Meanwhile, due to the rotatable adjusting lead-in wire of insulating bar and the distance of primary equipment, therefore for staff, can be with regard near operation, therefore simple, convenient.
