Definitions

  • Hybrid cable comprising a screen, power cables and at least one low voltage cable
  • the invention relates to a hybrid cable, comprising a screen, power cables and at least one low-voltage line.
  • Signal voltage lines ie low voltage lines having.
  • the invention is therefore the object of developing a hybrid cable, with a simple production should be executable. According to the invention, the object is achieved in the hybrid cable according to the features specified in claim 1.
  • Power cables and the at least one low voltage line are arranged within the screen, wherein a coaxial cable is disposed within the screen, which is the
  • the low-voltage line is the center conductor or outer conductor of the coaxial cable.
  • the advantage here is that a simple cost-effective production is possible.
  • Low voltage line voltages occurring is less than 50 volts and the
  • Rms value of the voltages occurring on the power lines more than 50 volts.
  • the advantage here is that only the hybrid cable must be laid in the system and thus no separate laying of multiple cables is necessary.
  • the screen has a braid of tinned
  • each power line is surrounded in each case by an electrical insulation.
  • the advantage here is that no short circuit occurs within the cable.
  • the shield of the hybrid cable is surrounded by electrical insulation.
  • a cross-sectional area in the direction of the longest extent of the cross-sectional area has a first region which is arranged between two further regions and is relatively narrowed to these two regions, ie in particular the extension of the cross-sectional area in the transverse direction in the first region Direction of the longest extent of the cross-sectional area is less extensive than in the two areas.
  • the filling body is made of an electrically insulating material.
  • the advantage here is that a good electrical insulation and ease of manufacture is inexpensive executable.
  • Hybrid cable surrounded room area arranged. As low as possible volumes of unfilled space can be reached.
  • the brake cable to another screen are arranged within the lines, which are each surrounded by insulation.
  • the advantage here is that the brake cable has a circular cross-section as possible, in particular even during production of the hybrid cable.
  • Packing are fixable.
  • the constriction as elastic deformation is caused by the brake cable pressing against the filling body on a first side of the filling body and by pressing on another side of the filling body
  • FIG. 1 shows a hybrid cable according to the invention is shown, which is provided for connecting a running as a three-phase motor electric motor with electromagnetically actuated brake and signal electronics.
  • the hybrid cable on the one hand power lines (U, V, W, N), which are used to power the motor with power. These cables are not shielded against each other. For example, these lines are provided for 380 volts and 50 to 60 hertz.
  • Each of the power lines has a copper wire surrounded by an insulating jacket.
  • a coaxial cable is provided in the hybrid cable.
  • Coaxial cable for itself has a center conductor 3, which is arranged centrally in the coaxial cable, and a screen 4, which is composed of a braid of tinned copper wires.
  • the shield 4 is used as an outer conductor and surrounded by insulation.
  • center conductor 3 Between center conductor 3 and outer conductor 4, an electrically insulating filler is arranged, so that the central position of the center conductor 3 is fixed.
  • Three lines 7 for supplying and controlling an electromagnetically actuated brake of the motor are designed as medium voltage lines.
  • These three lines 7 are each designed as a copper core with respective insulating jacket.
  • three filler 8 are provided, which are arranged with the lines 7 within the screen 9.
  • the shield again consists of a braid of tinned copper wires.
  • the screen 9 with the surrounding lines 7 and the packing 8 is also referred to below as a brake cable.
  • the brake cable, the hybrid cable and six other filler 6 and a different from these packing 10 are surrounded by a screen 2, in particular braid of tinned copper wires, the hybrid cable.
  • a screen 2 in particular braid of tinned copper wires, the hybrid cable.
  • an insulation 1 of the hybrid cable is arranged on the outside of the screen 2.
  • the further packing 6 are made of electrically insulating material and have a circular cross-sectional area.
  • Hybrid cable arranged and has a larger cross-sectional area than the other filler 6th
  • the filler 10 is in contact between the coaxial cable and the brake cable.
  • its cross-sectional area in the direction of its longest extent has a central region which is arranged between two outer regions and is designed to be narrowed relative to these two regions.
  • This constriction is caused by a deformation caused by pressing the coaxial cable on one side and pressing the brake cable on the other side.
  • the filler body has, as it were, indentations, the first of which is caused by the coaxial cable and the second is effected by the brake cable.
  • the coaxial cable is used only for the transmission of low-voltage signals, in particular for information transmission. Thus, only voltages less than 50 volts, in particular less than or equal to 48 volts, occur here.
  • the power lines (U, V, W, N) are designed for high voltage or medium voltage suitable and not twisted arranged in the hybrid cable. Preferably occur in the
  • the hybrid cable is performed without the brake cable.
  • V power line especially for the second phase three phase
  • N power line in particular for neutral and / or electrical ground

Landscapes

  • Insulated Conductors (AREA)
