Embodiment Construction

[0011] Such as figure 1 As shown, the device uses three-phase alternating current to work, and the working project is connected in series in the circuit. The programmable logic device S7-200 automatically monitors the circuit. In the initial process of the circuit, the mains branch is used to start. Transition to power saving branch for work.

[0012] In the present invention, when switching between any two paths among the power-saving branch, the commercial power branch, and the third connecting branch, or switching between the three gears, the first connecting branch and / or Participation of the second connection branch, the first connection branch and / or the second connection branch of the switch between the power saving branch, the mains branch and the third connection branch are connected to the mains contactor For the upper end and the lower end, after the path switching is completed, the first connection branch and / or the second connection branch of this piece will susp...

Abstract

The invention relates to a low-voltage power saver. An inlet wire of the power saver is electrically connected with a reactive compensation branch by a relay, and electrically connected with a power-saving branch with a relay, a commercial power branch with a relay, a communication branch with a relay and a first seamless connection branch which are connected in parallel; the power-saving branch is electrically connected with a first gear relay branch, a second gear relay branch, a third gear relay branch and a second seamless connection branch which are connected in parallel by a relay; and an outlet wire of the power saver is electrically connected with the first gear relay branch, the second gear relay branch, the third gear relay branch, the second seamless connection branch, the first seamless connection branch, the commercial power branch and the communication branch. The power saver is simple to operate, low in failure rate and high in safety coefficient.

Description

technical field [0001] The invention relates to a low-voltage power saver, in particular to a low-voltage power saver which uses a Siemens programmable logic device S7-200 for automatic control. Background technique [0002] As the name implies, the low-voltage power saver is a kind of saving the excess electric energy without changing the operating characteristics of the load, and removing the damage to the load, such as multiple harmonics, so as to achieve the purpose of saving electricity and prolong the life of the load at the same time. Service life, the current low-voltage power saver has the problems of complicated operation, low failure rate and low safety factor. Contents of the invention [0003] The technical problem to be solved by the present invention is: how to provide a low-voltage power saver with simple operation, low failure rate and high safety factor. [0004] The technical solution adopted in the present invention is: a low-voltage power saver, the i...
