Definitions
- the invention relates to a method for producing an electrical cable connection in which an electrical cable strand with an electrically conductive inner conductor and an electrically insulating insulating body enclosing the inner conductor is laid along a connecting path.
- the link extends expediently Zvi ⁇ rule a first and a second connection point.
- the cable connection can be provided, for example, between two high-voltage installations or components of high-voltage installations.
- Connection point can be, for example, a switchgear, ei ⁇ ne converter system or a substation with a Transforma ⁇ tor.
- Methods are known from the prior art, in which the cable connection is realized by means of a previously prepared and tested cable in a facility intended for this purpose.
- the cable is wound up to one of the two connection points.
- an energy cable is manufactured in a factory and transported to the place of use. For transport, the power cable is wound onto a cable reel. Due to size and weight limitations during transport, this results in a maximum achievable cable length of the power cable. Therefore, multiple cables must be connected by means of suitable cable sleeves to a cable harness at the site. However, such a method is relatively expensive.
- the object of the invention is to propose a method according to the species which is as cost-effective as possible.
- the object is achieved ⁇ by a method mentioned that the cable harness is manufactured at a place of installation and laid with its production.
- the cable harness is not manufactured in a factory but at the place of use itself, one of the locations of the installation, ie directly on the connecting line. This results in advantageous that any transport restrictions in terms of weight, dielectric strength of the insulation, bending radius are no longer restrictions.
- the cable harness can be laid as a whole.
- the use of cable sleeves can thus be dispensed with. In this way, a cost advantage over the aforementioned, known method is achieved.
- the laying can be done underground, for example.
- the cable harness is a power cable and is designed for transmission of electrical energy to high voltage.
- the power cable is designed to transmit electrical energy over long distances.
- the power cable therefore carries a direct or alternating current. It is for the transmission of electrical energy to high voltage by means of suitable measures known in the art, such as a suitable insulation tion, ertricht.
- the power cable on a
- the insulating body is produced by winding.
- individual layers of the insulating body are wound in succession or simultaneously on the inner conductor.
- the insulator can be made by extrusion.
- the insulating body is produced as a hollow body (ie in the form of a hollow tube), wherein the inner conductor is inserted into the hollow body.
- an electrically conductive inner layer is placed on ⁇ on an inner side of the insulating body in order to produce an electrical contact to the inserted inner conductor.
- the inner layer may be beispielswei ⁇ se a conductive paint layer.
- the insulating body comprises polyethylene and / or
- the insulator may comprise resin layers embedded in paper.
- the insulating body for increasing the mechanical stability and a
- the outer coating may comprise, for example, PVC.
- a source material is brought a ⁇ .
- the source material may be, for example, a Grezier ⁇ lat.
- the source material is used in particular to fill any voids within the insulator. In this way, in particular the longitudinal water tightness of the cable harness can advantageously be increased.
- non-invasive process monitoring is performed during manufacture of the wire harness. Since the cable ⁇ strand is laid on or immediately after its production, an invasive quality inspection can not be carried out (for example, with respect to dielectric strength).
- a non-invasive and non-destructive process in particular ⁇ monitoring or quality control instead, according to one embodiment of the invention proposed.
- the known methods can be used, for example, with the aid of X-ray radiation and / or ultrasound.
- the invention further relates to a cable connection between two connection points.
- the object of the invention is in this case to propose such a cable connection, which is as cost-effective as possible.
- the object is achieved by a cable connection with a Herge ⁇ by means of the method according to the invention presented harness.
- the advantages of the cable connection according to the invention arise in particular by the cost-effective production.
- the cable connection according to the invention does not contain cable joints, which reduces the cost of laying the cable connection in addition.
- FIG. 1 shows an embodiment of the method according to the invention in a schematic representation.
- a manufacturing unit is open shows ⁇ 1, which is located at a first connection point of a look electrical cable connection.
- ⁇ By means of the herstel ⁇ averaging unit 1 is a wire harness prepared in the following manner 10th
- An electrically conductive, flexible inner conductor 2 made of aluminum is wrapped or sheathed by a first insulating jacket 3 and egg ⁇ nem second insulating sheath 4.
- the two insulating shells 3, 4 may comprise, for example, polyethylene and / or paper soaked in resin.
- a source material is added in the form of a filling granulestik- for locking ⁇ close cavities and increasing the tightness.
- An insulating body 8 of the wire harness 10 comprises so ⁇ with in the case shown in the figure embodiment, the two insulating 3,4, the source material 5, the electrostatic ⁇ magnetic shield 6 and the cable coating 7.
- the wire harness 10 is below ground (in the preparation of the soil is indicated in the figure by the reference numeral 9) in the direction of a second connection point of the connection ⁇ route laid.
