Three-phase electricity-saving compensation controller

Abstract

The invention belongs to the technical field of connection devices of electronic plug-ins and electricity-saving compensation control, in particular to a three-phase electricity-saving compensation controller. The controller comprises a control box housing body, a three-phase power input hole, a three-phase compensation output hole, a three-phase socket hole, a compensation indicator lamp, a three-phase power input binding post, a compensation output binding post and an electricity-saving control module, wherein the three-phase power input hole, the three-phase compensation output hole, the three-phase socket hole and the compensation indicator lamp are arranged in the control box housing body, and the three-phase power input binding post, the compensation output binding post and the electricity-saving control module are arranged in the control box housing body. The electricity-saving control module comprises an acquiring unit, an adjusting unit, a PWM control circuit and a compensation adjusting circuit. According to the current change caused by change of load between the three-phase power circuit acquired by the acquiring unit, the PWM control circuit outputs pulse adjusting signals to control the compensation adjusting circuit so as to allow the compensation adjusting circuit to perform power compensation for the load on the three-phase power circuit and for an electric device on the three-phase power jack. According to the invention, power factors in the circuits can be adjusted, and harmonic waves can be eliminated, thereby saving energy and reducing circuit loss.

[0002] The power-saving supplementary control box is suitable for power transfer devices of various electrical equipment. It is convenient, time-saving, labor-saving, and easy to carry. It is a must-have electronic equipment for people in modern industrial production activities. All use three-phase power supply in large quantities, such as electric motors, electric welding machines, lathes, mixers, printing machines, servo machines, crushers, air compressors, oil presses, small central air conditioners and other electrical equipment. The power is large, the work flow is also large, and the power consumption is high. Harmonics, surges and transients are generated during operation and at the moment of startup or shutdown. Due to the existence of these conditions, it is easy to cause damage to the power supply line and cause power supply line damage. Therefore, installing a reactive power compensation device at the socket where the electrical equipment is connected can stabilize the voltage of the three-phase power supply network, improve the power factor, improve the utilization rate of equipment, improve the safety of equipment operation, and reduce the The active power loss of the power supply network has important practical significance
