Abstract

The present invention relates to the technical field of electric power production auxiliary equipment, more specifically, to a SYG copper-aluminum transition equipment clamp for distribution network, including the first connecting piece connected with the bus down-lead of the substation and two groups connected with the electrical equipment The second connecting piece is connected; two sets of second connecting pieces are arranged symmetrically on both sides of the center line of the first connecting piece, and a clamping piece is arranged on the outside of the second connecting piece. The present invention can adjust the distance between two sets of second connectors by setting two screw rods with opposite helical directions through the rotation of the screw rods to adapt to different types of outlet terminals. To avoid line faults caused by falling off between the second connecting piece and the outgoing terminal, the contact area between the transition equipment clamp and the outgoing terminal of the electrical equipment is increased by setting the clamping piece close to the second connecting piece, and the resistance value of the transition resistance is reduced , to reduce the impact of the construction process on the transition resistance, thereby solving the problem of heat-induced defect failures.

Example Embodiment

[0025] Example 1
[0026] like Figure 1 to Figure 3 Shown is the first embodiment of the SYG copper-aluminum transition equipment clip of the power distribution network of the present invention, including a first connector 1 connected to the down-conductor of the substation bus and two sets of second connectors connected to the electrical equipment 2; two sets of second connecting pieces 2 are symmetrically arranged on both sides of the center line of the first connecting piece 1, and a clamping piece 3 is closely attached to the outside of the second connecting piece 2; one end of the clamping piece 3 is connected to the first connecting piece 1 connect.
[0027] Specifically, the first connector 1 is a hollow cylindrical structure with one end open and one end closed, the second connector 2 is a copper sheet structure with a flat surface; the first connector 1 is composed of a conductive inner layer structure 11 and an insulating outer layer structure 12 The inner layer structure 11 is tightly connected with one end of the outer layer structure 12, and the outer layer structure 12 is provided with several fixed rings 13 arranged in parallel; it can not only ensure the continuous connection between the down-conductor and the outlet terminal, but also ensure that the operator Safety when clamping the first connecting piece 1 . The conductive inner layer structure 11 and the clamping member 3 in this embodiment are all made of aluminum, which has good ductility and is easy to operate.
[0028] Wherein, a transition piece 4 is connected between the first connecting piece 1 and the clamping piece 3, and the transition piece 4 is formed by stacking several identical soft connecting pieces 41; the transition piece 4 is provided with an outwardly protruding arc Structure 42. The clamping piece 3 is provided with a connecting hole 31 which is matched with the transition connecting piece 4. One end of the transition connecting piece 4 is welded and fastened to the first connecting piece 1, and the other end is fastened and connected to the connecting hole 31 by inserting, which is convenient for processing. , reduce the production cost; the two sets of clamping parts 3 are respectively provided with screw holes 32 with opposite thread directions, and the screw holes 32 are connected with a screw rod 33; By rotating the screw 33, the two groups of second connectors 2 can be moved closer or farther away, so as to adjust the distance between the two groups of second connectors 2 to match with the outgoing terminals of the electrical equipment, which is convenient for adjustment.
[0029] In addition, one end of the screw rod 33 is fastened with an insulating fixing cap 35, and the insulating fixing cap 35 is provided with knurling 36, which is convenient for the operator to screw in or out the screw rod 33 and increase the safety of operation; A retractable clamping member 5 is detached and connected, and the clamping member 5 is provided with a recess 51 that is matched with the clamping member 3, so that the distance between the two sets of second connecting members 2 can be maintained when the distance is adjusted to a suitable position. , to avoid line faults caused by falling off between the second connector 2 and the outgoing terminal.
