[0002] The phase sequence of the existing common three-phase plug-in electrical connection devices (three-phase plugs, sockets) is determined by the connection sequence of the plugs and sockets, and the phase sequence is fixed. If the phase sequence needs to be changed, re-wiring is required. Time-consuming and labor-intensive; moreover, if the operation is live, there will be dangers such as electric shock and burns

The present invention provides a three-phase rotary type phase modulation electrical connection device. The three-phase rotary type phase modulation electrical connection device comprises a three-phase plug and a socket. The three-phase rotary type phase modulation electrical connection device is characterized in that the three-phase rotary type phase modulation electrical connection device further comprises a turntable, a mounting bracket, a guide base, an upper cover, a transmission assembly and a conductive assembly; the transmission assembly comprises a transmission shaft, a cam group, a rolling wheel group, a pushing rod group and a compression spring group, wherein the cam group comprises five cams, the rolling wheel group comprises five rolling wheels, the pushing rod group comprises five pushing rods, and the compression spring group comprises five compression springs; and the conductive assembly comprises a fixed conductive group composed of six fixed conductive sheets, a movable conductive group composed of five movable conductive sheets, three input binding posts and three output binding posts. When the three-phase rotary type phase modulation electrical connection device is used, the turntable is rotated, so that the transmission shaft can be made to carry out transmission, and therefore, the cams can act, and as a result, the rolling wheels can be driven to move to drive the pushing rods to move up and down, and therefore, the movable conductive sheets and the fixed conductive sheets can be made to be in different mutual connection states, and phase modulation can be achieved. When the three-phase rotary type phase modulation electrical connection device is used, it only needs to carry out manual operation to make the plug achieve output disconnection, positive-sequence output and reverse-sequence output, and therefore, convenience in use and high security can be realized.
Description
technical field [0001] The invention relates to a three-phase power socket and a plug, in particular to a three-phase rotary phase-modulating electrical connection device capable of changing the phase sequence of a three-phase power supply through rotation. Background technique [0002] The phase sequence of the existing common three-phase plug-in electrical connection devices (three-phase plugs, sockets) is determined by the connection sequence of the plugs and sockets, and the phase sequence is fixed. If the phase sequence needs to be changed, re-wiring is required. Time-consuming and labor-intensive; moreover, if the operation is live, there will be dangers such as electric shock and burns. Contents of the invention [0003] The purpose of the present invention is to provide a three-phase rotary regulator which can conveniently make the plug in the disconnected output, positive sequence output and reverse sequence output working states by manual rotation operation, and ...
