Abstract

The present invention discloses a phase modulation power supply unit. The phase modulation power supply unit comprises two or more than two power supply switching units and a common driving unit, the common driving unit comprises a left side driving mechanism and a right side driving mechanism, the left side driving mechanism comprises a left driving electromagnet, a left driving rod, a left driving spring and a left fixed seat, the right side driving mechanism comprises a right driving electromagnet, a right driving rod, a left driving spring and a right fixed seat, and the number of the left driving springs and the number of the right driving springs are the same as the number of the power supply switching units; and the left driving rod and the right driving rod run through the horizontal sliding blocks of each power supply switching unit, each left driving spring is located at the left side of the corresponding horizontal sliding block of each power supply switching unit, each right driving spring is located at the right side of the corresponding horizontal sliding block of each power supply switching unit, and the horizontal sliding blocks are pushed by the left and right driving springs to move to the left and to the right.

Description

technical field [0001] The invention mainly relates to the field of distribution network power management, and in particular to a phase modulation power supply unit. Background technique [0002] In the existing three-phase input and single-phase output switches, or distribution switches with one input and multiple outputs, most of them are equipped with a mechanical or electromagnetic switch for each line, and the switching of the lines is realized by controlling the on or off of each switch. It is because there are many switch settings, the failure rate is high, and there is a probability of short circuit in the control process. There are also some switches in the market that use motor drive to realize line switching, which also has disadvantages such as high failure probability and single switching mode; [0003] Based on two vertical relationships, two objects that move in a straight line and have intersections in their motion trajectories have a mutual restriction rela...
