Description
Technical Field
The utility model relates to a copper bar technical field, more specifically relates to a crane span structure copper bar.
Background
At present, the metal sheath cross connection is needed in the laying process of the high-voltage transmission cable so as to weaken induced circulation and induced voltage. The connection point of the cable metal sheath is located in the grounding box, and the underground metal sheath is usually led out of the ground to the grounding box through the copper shell of the cable intermediate joint and the coaxial cable. Can install fixing device above the insulation board in the grounding box, fix a plurality of coaxial cable sinle silk of drawing forth on the design position of insulation board, then will connect the sinle silk on the fixing device through the copper bar and accomplish cable metal sheath's cross interconnection to guide induction cable to shift with this to weaken sensitive cable, reduce the line loss.
The copper bar is usually designed into a long bar shape as an important medium for cross connection, and holes are formed in two sides of the copper bar for connecting bolts and nuts for fixing. When the cable operation and maintenance personnel overhaul the grounding system, the bolt and the nut for fixing the copper bar need to be taken out, and then the copper bar is taken down and then the grounding system element of the grounding box is detected. And after the detection is finished, the copper bar needs to be reset. But because the cable can slightly displace in operation, the cable grounding box can also have a settlement phenomenon. The original insulating plate and the fixing device are subjected to a great external force. After the copper bar is dismantled, the insulation board and the fixing device are not bound, and then the insulation board and the fixing device are obviously deformed, so that the relative position of the hole sites is changed, and the angle of the hole sites is also changed. If want to insert original fixing device with the copper bar again just very difficult, often can waste very big manpower to the part damage appears easily, seriously influences the daily fortune dimension work of high tension cable. Can use the copper braid over braid of taking the line nose in the scheme that has now, utilize the copper braid over braid of a little overlength can solve the inaccurate problem of hole site to a certain extent, but the copper braid over braid is comparatively soft, can't be fine stereotype, and in narrow and small cross interconnection case, needs cross interconnection material again and can keep certain bent angle, just can cross the leap each other, therefore the copper braid over braid is wide application in high pressure cross interconnection case not.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome and be difficult to insert original fixing device after current copper bar is dismantled, and the shortcoming of too soft unable design of copper braid over braid in the current solution provides a crane span structure copper bar. The utility model discloses can adapt to the change of hole site on the insulation board, be convenient for detect the back copper bar reset, can also guarantee simultaneously that the crane span structure copper bar keeps certain shape in the interconnection case alternately.
In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a crane span structure copper bar, wherein, includes two copper bars and the copper braid over braid of buckling, two copper bars of buckling are connected respectively the crane span structure copper bar of both ends formation symmetry of copper braid over braid, every copper bar of buckling is kept away from the one end of copper braid over braid all is equipped with the connecting hole. In this technical scheme, two bent copper bars are connected through the both ends at the copper braid over braid, form the crane span structure copper bar of complete symmetry, bent copper bar can make the crane span structure copper bar keep certain shape in cross interconnection case, and the copper braid over braid can the change of the hole site on making the crane span structure copper bar adapt to the insulation board by appropriate amount deformation, and the connecting hole is used for crane span structure copper bar and insulation board to carry out fixed connection.
Furthermore, the bent copper bar is Z-shaped. The bent angle of the bent copper bar is a right angle. After two Z-shaped bending angles are connected through the copper woven belts in the technical scheme, the shape of a bridge frame with two high and low planes is formed, and other conventional strip-shaped copper bars can be crossed in the cross interconnection box.
Further, the copper braid over braid with the copper bar of buckling is connected through the welding. And the copper woven belt and the bent copper bar are welded through submerged arc welding.
Furthermore, threads are arranged inside the connecting hole. And bolts are arranged in the connecting holes to fixedly connect the bridge copper bar with the insulating plate.
Furthermore, the width of the copper braided strap is matched with the width of the bent copper bar. The copper braided strap is formed by braiding copper wires.
Furthermore, the surface of the bent copper bar is provided with a tin plating layer for preventing oxidation. The surface layer of the copper braided belt is provided with a tin coating for preventing oxidation.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model utilizes the deformation caused by the flexibility of the copper braided belt to adapt to the change of hole sites on the insulating plate; through the cooperation of buckling copper bar and copper braid over braid and being connected for the crane span structure copper bar has certain shape can stride other some conventional rectangular shape copper bars in the cross interconnection case.
