Dynamic balance energy system optimizing device

Abstract

The invention discloses a dynamic balance energy system optimizing device. The device consists of an iron core, a winding, a programmable logic controller (PLC), a voltage detecting device, a current detecting device and a core temperature detecting device, wherein each phase of winding of the three-phase winding is formed by connecting a plurality of sub-windings; the sub-windings are respectively wound on different iron core columns; each phase of winding is provided with a plurality of intermediate taps; a three-phase load is connected to a load tap; an automatic separating switch K2 is arranged between the winding behind the load tap and the winding before the load tap; an automatic bypass switch K1 is arranged between the load tap and the input end of the three-phase winding; and the intermediate taps and tail ends behind the load tap are connected with a zero point N through different contacts of different contactors. A voltage parameter and a current parameter are transmitted to the PLC and calculated and analyzed by the PLC, the number of the loaded sub-windings is changed by controlling the contactors to be opened and closed, and the effect of balancing three-phase electric energy is achieved through the electromagnetic exchange and inverse superposition of the winding.

Problems solved by technology

[0002] For the wasteful high-energy-consuming enterprises and large-scale commercial places, a thyristor phase-controlled device is generally used, which generates harmonics and pollutes the power grid. In some places, high-power phase-controlled devices are used to generate harmonics. Harmonics cause high-precision instruments in the enterprise to fail to read data normally, information is lost, and mechanical vibration, noise, and overvoltage will be generated on the motor, which will cause severe local overheating of the transformer. , It will also cause relay protection and automatic device malfunction, and make electrical measuring instruments inaccurate, interfere with the communication system, cause noise to reduce communication quality, and cause data loss in severe cases, making communication unable to work normally; another The automatic power factor compensation device with stepless regulation is used, which utilizes the natural physical property that the voltage of the capacitor in the AC circuit lags behind the current, compensates the current lag caused by the inductive load, and reduces the load current of the power supply line to save the line and The purpose of the loss of electrical load

However, this power saver is less effective for devices with high power factor, or even no

Another electromagnetic balance voltage regulating and power saving device has only one gear position and one parameter operation, and cannot track the user's electricity consumption in real time, resulting in sometimes saving electricity and sometimes not saving electricity. The electromagnetic balanced voltage regulating device cannot operate in one Optimum economical operation, because the parameters of voltage, current, power, and power factor of high-energy-consuming enterprises and large-scale commercial places change with the change of load every moment and every second, and none of the above devices can The load changes and changes, and the best power-saving effect cannot be achieved
