Three-phase load rotation phase modulation device and application thereof in power supply system

Abstract

The present invention discloses a three-phase load rotation phase modulation device. The device comprises an insulation sleeve and a rotor arranged in the insulation sleeve; the rotor comprises a cylindrical body; six metal sheets are respectively uniformly embedded at outer edges of the top surface and the bottom surface of the body along the circumference of the top surface of the body; the insulation sleeve comprises a hollow cylindrical vertical sleeve body, upper and lower ends of an inner bore of the sleeve body are both opened, and a bore wall of the lower end of the inner bore of the sleeve body towards a direction of a center line of the sleeve body is connected with a horizontally arranged annular plate; and the insulation sleeve is provided with two layers of elastic crimping conductive mechanisms which consist of an upper layer of an elastic crimping conductive mechanism arranged at the top end of the sleeve body and a lower layer of an elastic crimping conductive mechanismarranged at the bottom end of the sleeve body, wherein the upper layer of the elastic crimping conductive mechanism and the lower layer of the elastic crimping conductive mechanism are longitudinallysymmetrically arranged by taking a vertical middle section of the sleeve body as a plane of symmetry. The present invention further discloses an application of the three-phase load rotation phase modulation device in a power supply system. Through rotation of a rotor, phase modulation can be achieved with no need for shutdown of a whole distribution network.

Description

technical field [0001] The invention relates to a current regulating device. Background technique [0002] During the power supply process, the upstream line needs to supply power to each power consumption community. The incoming line of the community is generally two wires, one neutral wire and one live wire. The upstream circuit is usually a three-phase power supply, that is, there are three live wires and one neutral wire. The three live wires are A-phase line, B-phase line and C-phase line. [0003] In the existing power supply line structure, the incoming live wire of each community is connected to any one of the three live wires in the upstream line, and cannot be connected to the other two live wires. [0004] Therefore, with the existing power supply line structure, it is impossible to balance the load of the upstream line, resulting in a phase A line, B phase line and C phase line, one or two phase loads are too high, and may even be overloaded, but the other Or...
