Definitions
- the present invention relates to a method to provide a medium voltage interconnection for realizing an electrical connection between a receiving connector of a first equipment station and a receiving connector of a second equipment station.
- Such an interconnection is generally known in the art. It is made of a metal conductor at the ends of which are mounted electrical connectors.
- the electrical connector mates with the receiving connector generally forming part of a "bushing" of an equipment station.
- the equipment station is typically a transformer or switchgear in transformation station and the properties of the connectors are therefore preferably standardized.
- the electrical connector is moulded in polyethylene material so as to form a massive conductive core enclosed within a screened insulating body.
- the interconnection is relatively rigid and, additionally, is not available in different relative short lengths, e.g. of about 30 cm.
- a connector of this kind is described e.g. in FR-2 741 484.
- This document is directed to an electrical connector for connecting e.g. two cables, and comprising a conductive core including a metal conductor with at each end thereof, an electrical connector. It also comprises an elastic protective sleeve made of a layer of semi-conductive or conductive rubber.
- This connector is pre-fabricated by moulding a one-piece element.
- An object of the present invention is to provide an interconnection of the above known type but of which the electrical connectors are relatively more flexible, and available in different lengths without any significant extra-cost.
- the moulding process is replaced by an extrusion process.
- the conductive core is composed of a flexible conductor connected to two electrical connectors, whole enclosed within an elastic tube or sleeve to define connection insulated interfaces to mating the receiving connectors of the equipments.
- flexible interconnections are more adequate due to the flexibility of material and dimensions.
- the method of the present invention preferably comprises the steps of providing said electrical connector with a substantially conical shape of which the base has a diameter relatively larger than the diameter of said metal conductor, and of connecting said base to an end of said metal conductor.
- the present method further comprises the step of engaging one end of said flexible tube into an inner side of a conical bushing means made of insulating material and provided with said receiving connector so as to bring the electrical connector of the conductive core into contact with said receiving connector and said insulating layer of said flexible tube into contact with said inner side of said bushing means.
- said method comprises the steps of providing said flexible tube with, coaxially starting from the center:
- said method further comprises the steps of:
- the flexible tube or sleeve is then locked onto the electrical connectors or end-pieces of the conductive core to prevent any relative movement.
- the grooves may also be used to hold slidable outer clamps to mechanically clamp each electrical connector and possibly to achieve the external screening continuity between the interconnection and the mating parts.
- the present invention also relates to a medium voltage interconnection obtained by the method of the invention and adapted to electrically connect a receiving connector of a first equipment station and a receiving connector of a second equipment station.
- This medium voltage interconnection is characterized in that it comprises a conductive core including a metal conductor with, at each end thereof, an electrical connector adapted to mate said receiving connector, and a flexible tube having at least an insulating layer made of elastomeric material and covering the whole conductive core.
- said elastomeric material is a synthetic terpolymer of ethylene, propylene and diene [EPDM],
- said elastomeric material is a silicone.
- the term 'coupled' should not be interpreted as being limitative to direct connections only.
- the scope of the expression 'a device A coupled to a device B' should not be limited to devices or systems wherein an output of device A is directly connected to an input of device B. It means that there exists a path between an output of A and an input of B which may be a path including other devices or means.
- the flexible interconnection of the present invention is intended to be used for electrically connecting medium voltage electrical devices located in distinct equipment stations.
- an electrical device is for instance a switchgear or a transformer operating at voltages above 1 kVolt and enclosed in an equipment station that is a tank or a cubical.
- the equipment station is filled with an insulated medium that is oil fluid or gas, generally pressurized sulfur hexa-fluoride [SF6].
- SF6 sulfur hexa-fluoride
- the bushing well is an insulating molded hollow cone provided with a metallic rod interconnecting a connector at the top of the outer side of the cone with a receiving connector at the inner side of this cone, inside the well.
- the receiving connector meets the requirements of ANSI/IEEE Standard 386-1977 as is the case of the known bushing "K16O1PCC/K16O1PCC-R Clampable Apparatus Bushing Well with Gasket" of AMERACETM LTD (10 Esna Park Drive Markham, Ontario, Canada L3R 1E1 /1 November 1983). It is to be noted that bushing wells with other dimensions but still matching the present interconnection may also be used.
- One side of the bushing is immersed in the insulated medium of the equipment station and electrically connected to the electrical device, whilst the inner side of the cone is in the ambient air and provided with the receiving connector designed to receive one end of the flexible interconnection.
- the flexible interconnection comprises a conductive core surrounded by a flexible tube that will be explained in detail below.
- the conductive core is made of a metal flexible conductor 2 provided at each end with an electrical connector, indicated by arrows 3 and 4. Each connector 3/4 is adapted for mating the receiving connector of the bushing.
- the electrical connector 3/4 has a central blind hole 5/6 for connecting to a respective receiving connector of the bushing and has a conical shape of which the base 7/8 is respectively connected to an end of the metal flexible conductor 2.
- This base 7/8 has a diameter that is larger than the diameter of the metal conductor 2.
- the electrical connector 3/4 is further provided with an external locking ring 9/10 mating in an internal ring groove of the flexible tube.
- the conductive core 1 is covered, protected and insulated by a flexible tube, generally indicated by 11 in the Figs. 2a, 2b and 3, and preferably made of up to three layers of material.
- the flexible tube 11 is a moulded or extruded tube made of a first semi-conductive layer 12 (at the inside), an insulating layer 13 made of elastomeric material, and a second semi-conductive layer 14 (at the outside).
- the elastomeric material of the insulating layer 13 is preferably a synthetic terpolymer of ethylene, propylene and diene [EPDM]. Additionally, this EPDM may be recycled and is thus friendly for the environment.
- the tube 11 preferably has the same length as the conductive core 1.
- the flexible tube 11 is then prepared for receiving the conductive core 1, as shown at Fig. 3. Therefore, each end of the second semi-conductive layer 14 is removed at a certain distance up to the insulation material 13. At the same time, an internal ring groove 15 is provided at each end in the first semi-conductive layer 12 and partially in the insulating layer 13 of the flexible tube 11. The flexible tube 11 is then radially expanded and the conductive core 1 is slided therein.
- the flexible tube is released over the conductive core 1 in order to obtain a resulting medium voltage interconnection as shown at Fig. 4.
- the flexible tube 11 has now taken the shape of the underlying conductive core 1 and the latter is prevented to move therein owing to the mating external locking ring 9/10 of the conductive core and the internal ring groove 15 of the tube.
- the first semi-conductive layer 12 of the tube is in contact with the metal flexible conductor 2 and the connectors 3/4.
- each end of the so obtained interconnection may then be engaged into an inner side 16 of a conical bushing, generally indicated by an arrow 17, as described above, and mounted in a hole of a wall 18.
- the receiving connector 19 of the bushing 17 is so brought into contact with the electrical connector 3 of the conductive core via its hole 5, whilst the insulating layer 13 of the interconnection is brought into contact with the inner side 16 of the bushing.
- a fixing ring is provided over the conductive core at each end thereof.
- the fixing ring 20 On the left side of the interconnection, the fixing ring 20 abuts against the base 7 of the conical electrical connector 3 covered by the flexible tube and is mechanically fixed (not shown) to the bushing 17.
- a metal flexible protection (not shown) can be mounted on the outside of the tube to take the short-circuit currents.
- the insulating layer of the bushing device may also be a molded elastomeric material, preferably a synthetic terpolymer of ethylene, propylene and diene [EPDM] as for the insulating layer 13 of the flexible tube 11.
- EPDM ethylene, propylene and diene
