Description

Technical Field

[0001] The utility model relates to the technical field of electric energy management and provides a power-saving protection device adopting a three-dimensional structure movement. Background Art

[0002] There are problems of power waste and excess energy consumption in the existing power systems, which not only cause waste of electric energy resources, but also cause damage to power equipment. In order to avoid the above problems, it is necessary to install a power-saving protection device in a power system or power equipment, the purpose of which is to remove power waste such as transients, surges, harmonics, improve power factor and save electricity, and adjust excess energy consumption to achieve the purpose of power saving. At present, the existing power-saving devices have their own functional characteristics, but also have their own limitations. The existing power-saving devices cannot balance the three-phase current in real time, and the reactive power compensation technology cannot adjust the three-phase balance in real time. It is easy to over-compensate or under-compensate. The equipment structure is complex, especially the electricity in it is easy to be damaged, resulting in a shorter service life, requiring frequent maintenance, and a short service life. It is impossible to optimize the power saving protection of the overall power system, and some power-saving equipment has large self-loss, and the actual power saving effect is limited. Therefore, we need a power-saving protection device that effectively reduces high-order harmonics, suppresses pollution such as surge transients, and increases service life. Utility Model Content

[0022] Below, combined with the attached Figure 1 To Attachment Figure 5 As well as specific implementation methods, the present invention is further described. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] like Figures 1 to 5 As shown, a power-saving protection device using a three-dimensional structure movement includes a movement 1, a chassis 2, a circuit component 3 and a control system 4;

[0024] Specifically, Figure 1 As shown, the chassis 2 is a rectangular cabinet with a supporting horizontal plate 21 at the bottom. The movement 1 is arranged at the bottom of the chassis 2, i.e., above the horizontal plate 21. The movement 1 is connected to the control system 4 through the loop assembly 3. The control system 4 is used to detect the specific power status of the movement 1 and whether the control loop assembly 3 is connected. The movement 1 includes an iron core group 11 and high and low coil windings 12. The iron core group 11 is an equilateral triangle ring iron core 11. The high and low coil windings 12 are located at the top corners of the equilateral triangle ring iron core 11. The distances between the three high and low coil windings 12 are the same and they are distributed in an equilateral triangle. Specifically, as Figure 3 , 4As shown in 5, the equilateral triangular ring core 11 includes three rounded rectangular parts of the same shape, and the straight sides of the rounded rectangular parts and the adjacent rounded rectangular parts are closely attached to each other and assembled at a central angle of 120° to form the equilateral triangular ring core 11. The vertical cross-section of the equilateral triangular ring core 11 is an equilateral triangle, and the straight sides of the rounded rectangular parts and the adjacent rounded rectangular parts are closely attached to form the core column of the core, and the high and low coil windings 12 are arranged on the core column. The three-dimensional structure of the movement 1 establishes an independent micromagnetic field for each phase, and adjusts the three-phase magnetic field in real time through three closed loops to solve the imbalance of the three-phase current, saving energy while increasing the service life of the load equipment. At the same time, movement 1 adopts a special manufacturing technology of multi-winding ring cross interconnection. According to Lenz's law, movement 1 will present an overall reactance characteristic of "low pass and high resistance", which will make most of the high-order harmonics and currents of each phase cancel each other out or absorb each other and convert them into magnetic energy. The compensation winding will then synchronously compensate the converted current to the load end, thereby greatly reducing the power loss of the load caused by eddy current, harmonic components, etc.

[0025] As a specific description, the circuit component 3 includes a main circuit component 31 and a secondary circuit component 32, the main circuit component 31 includes a main circuit vacuum AC contactor 311 and a main circuit connecting copper bar 312, the main circuit positive air AC contactor is connected to the control system 4 and the movement 1 through the main circuit connecting copper bar 312, the secondary circuit component 32 includes three secondary circuit vacuum AC contactors 321 and a secondary circuit copper bar 322, and the three secondary circuit vacuum AC contactors 321 are connected to the movement 1 and the control system 4 through the secondary circuit copper bar 322. Under the control of the control system 4, the state of each magnetic field in the three-phase magnetic field can be monitored in real time, so that the size of each phase magnetic field can be controlled through the secondary circuit component 32, so as to balance the three-phase current in real time, and ensure the stability and reliability of the device.

[0026] As a further optimization, the device further includes a heat dissipation device 5, which is disposed at the bottom of the chassis 2 and is connected to the control system 4 to effectively dissipate heat and prevent overheating.

[0027] As a specific description of the control system 4, the control system 4 includes a control panel, a power monitoring module, a switch 41 and a display module 42. The switch 41 includes a gear switch 41 and a knob switch 41 for adjusting the mains power and the energy-saving circuit. The display module 42 includes a display screen, a power indicator light, a power-saving indicator light and a bypass indicator light. The power data and power-saving status can be viewed in real time through the display screen, and can be adjusted immediately as needed. In addition, various data can be remotely monitored through the power monitoring module, and power data can be mastered in real time. The knob switch 41 can realize one-key seamless switching between power saving and mains power, solving the technical problem of switching power supply without power outage.
