  • Publication number: 20190006081
    Abstract: An apparatus for electrically connecting at least four electrical conductors includes a connecting element and at least four shielding pipes, which are each provided for receiving at least one conductor. In order to enable a simple and economical connection, the connecting element forms pipe connection pieces and each connection piece is integrally joined or materially bonded to a respective shielding pipe.

  • Patent number: 10056886
    Abstract: A continuously variable saturable shunt reactor includes a laminated core having two wound limbs for each phase connected by yokes. A network winding branch is disposed on each limb, high-voltage ends of winding branches of a phase are connected to a phase conductor and low-voltage ends of winding branches are connected to a DC voltage source, to reduce power of the DC voltage sources, degree of distortion of the operating current and control error, and to reduce the number of DC voltage sources. The DC voltage source includes two stabilized, single-pole-grounded power converters with opposite polarities and two electronic transistor changeover switches controlled by a control system, for each phase. The control system feeds direct current to the winding branches of a phase in pulses using the switches and the direct current is fed into the winding branches at opposite poles from different power converters.

  • Patent number: 9859701
    Abstract: A connection element for electrically conductive connections of at least four electric conductors. The connection element has a metallic electrode which has a cavity for merging the conductors and an opening into the cavity for each conductor. At least the outer surface of the electrode is surrounded with a paper insulation.
