Description
Technical Field
[0001] The present invention relates to the technical field of power-saving equipment, in particular to an intelligent power saver. Background Art
[0002] Traditional energy-saving technologies are mostly limited to small-load lighting and power energy saving. Better-developed technologies include high-voltage frequency conversion technology for high-power air conditioners, fans, and water pumps, and large temperature difference cold storage technology. However, they also have limitations and local energy saving, and cannot meet the comprehensive energy-saving needs in complex power grid systems and diversified electricity usage scenarios.
[0003] In complex power grid systems, especially industrial power grids with a large number of nonlinear loads, a large number of harmonics are generated. Most traditional energy-saving technologies do not have a complete harmonic control function. For example, some simple inductive energy-saving devices, although they can limit the current through the reactor, are powerless against harmonic currents. The presence of harmonics will cause distortion of the grid voltage and current waveforms, increase equipment losses, reduce power quality, and may even cause equipment failure. Moreover, in complex power grid systems, three-phase imbalance is relatively common. Traditional energy-saving devices rarely have effective three-phase balance adjustment functions. For example, in some rural power grids or small factory power grids, the large number of single-phase loads connected will cause three-phase imbalance. Traditional energy-saving devices cannot effectively adjust this imbalance. The unbalanced three-phase voltage and current will increase transformer and line losses and reduce power transmission efficiency. In response to the shortcomings of the existing technology, the present invention provides an intelligent energy saver to solve the above problems. Summary of the Invention

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0037] Example 1:
[0038] The embodiment of the present invention discloses an intelligent power saver. Figure 1-3 As shown, the energy saver is connected to the power grid system using a hybrid architecture of parallel and distributed. The energy saver includes:
[0039] Multi-phase winding transformers are composed of multiple mutually insulated windings and can be flexibly configured according to actual load requirements. Multi-phase winding transformers reduce the transformer's own hysteresis loss and eddy current loss, reduce heat generation, and improve voltage regulation and waveform distortion, providing a higher-quality power foundation for subsequent power-saving processing.
[0040] like Figure 3 As shown in the figure, the multi-phase winding transformer consists of multiple mutually insulated windings. The figure shows the winding layout of the three phases A, B, and C and the neutral line N. This structure can be flexibly configured according to actual load requirements to adapt to different power usage scenarios and load types.
[0041] Phases A, B, and C each have corresponding windings A, B, and C, which are connected together using a specific connection method. This connection method helps optimize electromagnetic balance, reduce the transformer's own hysteresis and eddy current losses, reduce heat generation, and improve power conversion efficiency, while also improving voltage regulation and waveform distortion.
[0042] The neutral line (N) and the three-phase windings (A, B, and C) together form the transformer's wiring structure. The neutral line plays an important role in achieving three-phase balance, stabilizing voltage, and handling zero-sequence current, helping to improve power quality and system stability.
[0043] The protection system features multi-level fault detection and protection capabilities, including a power quality monitoring unit.

[0047] The transmission system supports multiple data transmission methods, including wired and wireless. The transmission system uses multiple advanced communication technologies such as 5G, LoRa, Wi-Fi, Bluetooth, Ethernet, etc. to achieve fast and stable data transmission. It can adapt well to both wired and wireless transmission methods, ensuring that power quality data, energy saver operation status information, etc. can be transmitted to cloud servers, user terminal devices, and energy management systems in a timely and accurate manner, realizing efficient data sharing and remote monitoring.
