Description

Technical Field

[0001] This invention relates to the field of electromagnetic energy-saving technology, specifically providing a modular electromagnetic energy-saving device and method. Background Technology

[0002] Electromagnetic energy-saving technology mainly utilizes the principles of electromagnetic balance and electromagnetic voltage regulation to intelligently adjust the actual output power based on load changes and the actual parameters of the current power supply. This achieves perfect matching and allows excess energy to be transferred to the power supply in a timely manner, improving the power factor, significantly reducing losses on transmission lines, effectively increasing energy utilization, increasing system capacity, improving voltage fluctuations, reducing ineffective losses in electrical equipment, and extending the service life of equipment. Ultimately, this achieves comprehensive energy saving and high-efficiency energy conservation benefits.

[0003] Currently, energy-saving equipment mainly uses a single electromagnetic core, configured according to the transformer capacity. This leads to a mismatch between the actual operating capacity and the configured capacity, with the actual operating capacity often being less than 50% of the configured capacity. This results in poor operating performance and high energy consumption. Furthermore, in the event of a fire, the entire equipment is extremely difficult to ignite and rescue. Summary of the Invention

[0004] To address the aforementioned issues, this invention employs a modular design approach, utilizing multiple energy-saving modules connected in parallel. An intelligent control module dynamically switches these modules in real-time based on system operating conditions, optimizing the overall energy-saving performance while minimizing its own losses and further improving the overall fault tolerance of the energy-saving device. The failure of a single energy-saving module does not affect the operation of the entire device. Furthermore, in the event of a fire, the modules are designed with a quick-connect structure, allowing for rapid removal of the burning module, thus limiting the fire's spread and significantly reducing the difficulty of firefighting.

[0005] The technical objective of this invention is to address the aforementioned problems by providing a modular electromagnetic energy-saving device and method.

[0006] In one aspect, the present invention provides a modular electromagnetic energy-saving device, the device having a modular structure, including an intelligent control system and several energy-saving modules, wherein the several energy-saving modules are connected in parallel with each other;

[0007] The intelligent control system controls the entry and exit of the control node modules to match the overall power-saving equipment's capacity with the actual system's operating capacity, achieving optimal power-saving effects and reducing its own losses.

[0008] Furthermore, the intelligent control system comprises three parts: a voltage and current sampling module, an embedded control system, and a relay output, wherein:

[0009] The sampling module is responsible for acquiring analog quantities of voltage, current, and temperature, and converting them into digital quantities for use by the embedded system.

[0010] The embedded control system is responsible for processing operating data, setting protection thresholds and issuing protection actions, selecting the level of system power saving efficiency, and adjusting the number of operating modules.

[0011] The relay output module is responsible for executing the actions of the embedded system, controlling the switching of the power-saving module and the system's rapid protection, and controlling the automatic switching of the power-saving mode of the power-saving module.

[0012] Furthermore, the device also includes a rapid protection device connected in parallel with the power-saving module. This rapid protection device is constructed using thyristors. When the intelligent protection device detects an abnormal operation of the node module or an overload, the intelligent control system immediately issues a thyristor conduction command, switching the operating current to flow through the thyristor, thereby protecting the power-saving module and achieving rapid protection in fault conditions.

[0013] Furthermore, the device also includes a bypass device connected in parallel with the energy-saving module. The bypass device is constructed using a mechanical contactor, which is controlled by an intelligent control system to control the overall energy-saving equipment's operation and shutdown, achieving rapid protection in fault conditions.

[0014] Furthermore, the energy-saving module includes an electromagnetic core, which is composed of a series-connected and out-of-phase wound reactor and a set of parallel fixed autotransformers combined on the same three-column iron core.

[0015] Furthermore, the series-connected, out-of-phase wound reactor includes output phases: R, S, T, and input phases: r, s, t, with the following winding method:

[0016] The R-phase input line is first wound in the forward direction on the R-phase magnetic core, then wound in the reverse direction on the S-phase magnetic core, and then wound in the forward direction back on the R-phase magnetic core before being led out to r.

[0017] The S-phase input line is first wound in the forward direction on the S-phase magnetic core, then wound in the reverse direction on the T-phase magnetic core, and then wound in the forward direction back on the S-phase magnetic core before being led out to s.

[0018] The T-phase input line is first wound in the forward direction on the T-phase core, then wound in the reverse direction on the R-phase core, and then wound in the forward direction back on the T-phase core before being led out to t.

[0019] Furthermore, the parallel fixed autotransformer is equipped with three switches, which are controlled by an actuator PLC to select a fixed voltage regulation level.

[0020] In another aspect, the present invention provides a modular electromagnetic energy-saving method. The method adopts a modular structure, in which several core electromagnetic energy-saving cores are arranged in multiple energy-saving modules. By connecting multiple energy-saving modules in parallel, an overall energy-saving device is constructed. The capacity of the overall energy-saving device is flexibly matched according to the number of energy-saving modules configured in the module. Through an intelligent control system, the energy-saving modules are dynamically switched in real time according to the operating conditions of the circuit system, so that the energy-saving device achieves the optimal energy-saving effect, while reducing its own losses and further improving the fault tolerance rate of the overall energy-saving device.

[0021] Furthermore, the intelligent control system comprehensively monitors the operating status of the energy-saving equipment through installed intelligent sensors for voltage, current, and temperature; it uploads the information to the upper-level control system (cloud platform, etc.) via network (local network cable, 4G, 5G), and schedules the activation and deactivation of the overall energy-saving equipment according to the commands of the upper-level control system.

[0022] Furthermore, by configuring bypass devices, fast protection devices, and intelligent control systems, the method can flexibly enable and disable the overall energy-saving equipment, as well as provide rapid protection in fault conditions.

[0023] Compared with the prior art, the modular electromagnetic energy-saving device and method of the present invention have the following outstanding advantages:

[0024] This invention enables the overall energy-saving equipment to match the system's operating capacity in real time, achieving optimal energy-saving effects and reducing its own losses. Furthermore, its modular design improves the overall energy-saving equipment's failure rate and facilitates maintenance. It allows for equipment maintenance and replacement without shutting down the entire energy-saving equipment and enhances fire safety. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] like Figure 1As shown, a modular electromagnetic energy-saving device is constructed using a 1000kVA transformer capacity and 200kVA capacity energy-saving modules. The overall energy-saving device consists of 5 energy-saving modules, 1 bypass device, 1 fast protection device, and 1 intelligent control system.

[0031] Five energy-saving modules are connected in parallel, as are the bypass device and the fast protection device; for example Figure 3 , 4 As shown, each energy-saving module contains an advanced electromagnetic core. The core consists of a series-connected, out-of-phase wound reactor and a set of parallel fixed autotransformers mounted on the same three-limb iron core. The three-phase current is input via RST and output from the rst terminal. The series-connected, out-of-phase wound reactor is as follows... Figure 3 As shown in the diagram, the R-phase input line is first wound in the forward direction on the R-phase core, then wound in the reverse direction on the S-phase core, and then wound back in the forward direction on the R-phase core before being led out to r. The S-phase is wound in the same manner as the T-phase, and the T-phase is wound in the same manner as the R-phase. A parallel fixed autotransformer is shown below. Figure 4 As shown, a fixed voltage adjustment level can be selected via three switches.

[0032] The intelligent control system controls the entry and exit of the control node modules to match the overall power-saving equipment's capacity with the actual system's operating capacity, achieving optimal power-saving effects and reducing its own losses.

[0033] like Figure 2 As shown, the intelligent control system comprises three parts: a voltage and current sampling module, an embedded control system, and a relay output.

[0034] The sampling module is responsible for acquiring analog quantities of voltage, current, and temperature, and converting them into digital quantities for use by the embedded system.

[0035] The embedded control system is responsible for processing operating data, setting protection thresholds and issuing protection actions, selecting the level of system power saving efficiency, and adjusting the number of operating modules.

[0036] The relay output module is responsible for executing the actions of the embedded system, controlling the switching of the power-saving module and the system's rapid protection, and controlling the automatic switching of the power-saving mode of the power-saving module.

[0037] The device also includes a fast protection device connected in parallel with the power-saving module. This fast protection device is constructed using thyristors. When the intelligent protection device detects an abnormal operation of the node module or an overload, the intelligent control system immediately issues a thyristor conduction command, switching the operating current to flow through the thyristor, thereby protecting the power-saving module and achieving fast protection in fault conditions.

[0038] The device also includes a bypass device connected in parallel with the power-saving module. For example... Figure 1 , 3 As shown in Figure 4, the bypass device is constructed using a mechanical contactor. The contactor is controlled by an intelligent control system to control the operation and shutdown of the overall energy-saving equipment, thereby achieving rapid protection under fault conditions.

[0039] The overall energy-saving equipment is equipped with a display device, buttons, etc. The display device shows the equipment operation information, and the buttons enable functions such as putting the equipment on and taking it off.

[0040] The capacity of the overall energy-saving equipment is flexibly matched according to the number of energy-saving modules configured. Through the intelligent control system, the energy-saving modules are dynamically switched on and off in real time according to the operating conditions of the circuit system, so that the energy-saving equipment can achieve the optimal energy-saving effect, while reducing its own losses and further improving the fault tolerance rate of the overall energy-saving equipment.

[0041] The intelligent control system comprehensively monitors the operating status of the energy-saving equipment through installed intelligent sensors for voltage, current, and temperature; it uploads the information to the upper-level control system (cloud platform, etc.) via network (local network cable, 4G, 5G), and schedules the activation and deactivation of the overall energy-saving equipment according to the commands of the upper-level control system.

[0042] The embodiments described above are merely preferred embodiments of the present invention.
