Definitions

the present invention relates to surge protective devices intended for the protection of power lines, in particular of medium voltage overhead lines.
the insulation element arranged between the two capsules or terminal connection electrodes is constituted by a stack of varistors based on zinc oxide (Zn0) maintained under axial pressure.
this stack and the elastic pressure means are contained inside a rigid tube made of an insulating material, itself sheathed by a plastic envelope, the assembly formed by said tube and envelope giving the aforementioned stacking the mechanical strength and sealing necessary for the practical use of the device.
the invention consists in having between the facing faces of the constituent elements (varistors and electrodes) of the insulation stack, intermediate parts with corrugated profile which by crushing the electrical connection and which are profiled to provide free areas suitable for receiving the adhesive layer necessary for the mutual assembly of the aforementioned elements.
the device shown in fig. 1 essentially comprises an insulation element formed by the rigid and resistant assembly of a stack of varistors 1 maintained under pressure between two terminal connection electrodes 2, which element 1-2 is covered in a sealed manner by an insulating envelope 3 which with annular projections 3a is directly obtained by overmoulding a synthetic material on said member.
the mode of implementation shown in fig. 2 and 3 uses a intermediate piece 4 formed by a washer with a corrugated profile, the outside diameter of which is slightly less than that of each of the varistors 1. On the transverse face of each of these is deposited, for example by a screen printing process, a layer of glue 5 in the form of a disc, the diameter of which is less than the inside diameter of the corrugated washer 4.
each adhesive disc 5 is lined with an adhesive ring 50 which surrounds the washer 4.
the adhesive layer 5 is in the form of two rigid pads which occupy the opening of the corrugated washer 4 and which cooperate with an intermediate disc 6, capable of being made either of an elastomer or of aluminum .
This central disc 6 is intended to improve, by crushing, the elastic pressure effect exerted on the varistors 1.
FIG. 8 to 11 Illustrated in fig. 8 to 11 another embodiment of the invention, according to which the intermediate piece provided between the facing faces of the varistors 1 is constituted by an insert 40 comprising a central part integral with radial branches (in number four in the example considered), each of these branches having a wavy profile.
Fig. 10 shows the assembly obtained after axial pressure and crushing of the corrugated profile of the insert 40. It was further assumed that the bonding was here ensured by the synthetic material which is overmolded on the insulating body of the arrester for the realization of the outer casing 3, which material is introduced at 30 between the branches of the insert 40.
the shape of the intermediate piece 4 or 40 can vary to a large extent, provided that this piece, due to the elastic deformability of its constituent material and having regard to its initial profile, is capable of collapsing during bonding to guarantee a good connection and that said conformation ensures the distribution of the mechanical assembly and electrical connection zones.
