Description

Technical Field

[0001] The invention relates to the field of high-voltage power saving, and in particular to an electromagnetic balanced winding high-voltage power saver. Background Art

[0002] The electromagnetic balanced winding high-voltage energy saver is an energy-saving device used in high-voltage power systems. It is mainly based on the principle of electromagnetic balance. Through a specific winding structure and electromagnetic interaction, it optimizes the use of electric energy to achieve energy saving and improve the quality of electric energy. In the fields of industry, commerce and municipal administration, electricity consumption is an important cost expenditure. When many equipment in high-voltage power systems are in operation, due to their own characteristics, they will produce problems such as reactive power loss and three-phase imbalance, resulting in waste of electric energy. The electromagnetic balanced winding high-voltage energy saver can effectively reduce these unnecessary power losses, thereby reducing the energy consumption costs of enterprises and users.

[0003] In the current operation of high-voltage energy savers, a single set of electromagnetic balancing windings is often provided. Energy savers with only electromagnetic balancing windings have relatively limited adaptability when dealing with different power grid environments, load changes, etc. This may result in large fluctuations in the energy-saving effect of the equipment when facing situations such as voltage fluctuations and sudden load changes, and the equipment may not be able to consistently maintain an efficient and stable energy-saving operation mode.

[0004] Therefore, in view of the current high-voltage energy saver's single set of electromagnetic balancing windings, limited adaptability to changes in power grids and loads, and large fluctuations in energy-saving effects, a high-voltage energy saver with electromagnetic balancing windings can be designed. The metering voltage transformer and metering current transformer in the device not only play a role in measuring voltage and current, but also provide data support for adjusting the phase relationship between current and voltage. Through precise metering, the control of reactive power transmission and loss can be better achieved. This is an innovative way to combine metering with power-saving regulation functions. Summary of the invention

[0005] In order to overcome the current high-voltage energy saver with a single set of electromagnetic balance windings, the adaptability is limited when dealing with changes in the power grid and load, and the energy-saving effect fluctuates greatly.

At the same time, the outer shell can also play a certain shielding role for the internal components, reduce the impact of external electromagnetic interference on the power-saving component, and help improve the power-saving efficiency of the device. The installation component is installed inside the outer shell to provide support for the power-saving component. It can ensure that each component in the power-saving component is in a stable working position. The stable installation helps to reduce the shaking or displacement between the components. The electromagnetic interference generated can improve the accuracy of measurement, which in turn helps to more accurately adjust the current and voltage phase relationship to reduce reactive power loss and achieve better power saving effects. The oil temperature thermostat can monitor the oil temperature in the transformer oil barrel. When the oil temperature is too high, it may affect the performance of the electrical equipment in the device, resulting in increased energy loss and possible transformer burning due to current overload. Through the monitoring of the oil temperature thermostat, timely measures can be taken to control the oil temperature to avoid reducing the power saving efficiency of the device due to excessive oil temperature and eliminate the risk of burning caused by current overload, ensuring that the device operates in an efficient state and achieving both safety and energy saving.

[0015] Beneficial effects of the present invention:

[0016] 1. The power-saving components of this device include a metering voltage transformer and a metering current transformer, which are installed on the first-level mounting frames on both sides of the shell, with reasonable and stable positions. The two transformers can accurately measure the voltage and current values, and provide an accurate basis for adjusting the phase relationship between current and voltage by transmitting the measured data to the buzzer controller. The electromagnetic balancing winding is installed on the top of the transformer oil barrel, and the phase relationship is adjusted according to the voltage and current data obtained by measurement, thereby reducing the transmission and loss of reactive power. Many power savers on the existing market are insufficient in terms of metering accuracy, resulting in inaccurate phase relationship adjustment, while this device can achieve this goal. Reasonable layout and precise design of metering components can reduce reactive power more effectively. For example, some traditional energy savers may only reduce part of the reactive power due to metering errors. This device can achieve deeper reactive power reduction based on precise metering, thereby improving energy saving efficiency. Stable oil level ensures the normal function of transformer oil. Appropriate oil level helps maintain good insulation performance, prevent leakage, and reduce power loss. At the same time, effective heat dissipation function ensures that components such as electromagnetic balance windings work at appropriate temperatures, avoiding problems such as increased resistance and transformer burning due to excessive temperature, further improving energy saving efficiency.

This design helps to form an effective ventilation and heat dissipation channel. The fans 110 can accelerate the air flow and discharge the heat generated by the internal operation of the device to the outside through the rear ventilation slots 109 to prevent the internal temperature of the device from being too high. An identification plate 105 is installed at the lower center of the front end of the cabinet door 101. The front end of the cabinet door 101 is located below the identification plate 105 and two sets of front ventilation slots 108 are opened from top to bottom.

A reserved hole for installing the sealing plug 103 is opened from bottom to top at the front end of the cabinet door 101 near one side edge. The identification plate 105 is installed at the lower center of the front end of the cabinet door 101. This position is relatively conspicuous, which is convenient for operators, maintenance personnel and other relevant personnel to quickly obtain relevant information about the device.

[0028] See also Figure 1-Figure 2In this embodiment, a handle 107 is installed at the front end of the cabinet door 101 below a group of sealing plugs 103, a secondary window 111 is installed at the front end of the cabinet door 101 near the primary hinge 102, a square groove for installing the secondary window 111 is opened through the cabinet door 101 near the primary hinge 102, a primary window 106 is installed at the center of the front end of the observation door 112, and a square groove for installing the primary window 106 is opened through the observation door 112. The secondary window 111 is installed at the front end of the cabinet door 101 near the primary hinge 102, and is installed through the square groove opened through the opening. This position allows the operator to see through the secondary window 111 without fully opening the cabinet door 101. 1 observes part of the internal situation of the device. The front end of the observation door 112 is located below the primary window 106, and a charge display 204 and a thermometer 210 are linearly installed from left to right. The front end of the observation door 112 is located below the charge display 204 and three sets of buttons 207 are linearly installed from left to right. The charge display 204 and the thermometer 210 are linearly installed from left to right below the primary window 106 at the front end of the observation door 112. The charge display 204 adopts DXN-Q. This layout enables the operator to conveniently view the charge status information displayed by the charge display 204 and the temperature information displayed by the thermometer 210 while observing the internal situation of the device through the primary window 106.

[0029] During operation, when the high-voltage power saver starts to work, the housing 1 provides physical protection for the internal power saving components and installation components to prevent adverse factors such as external mechanical collisions, dust, moisture, etc. from affecting the normal operation of the internal components. The rear ventilation slots 109 and the fan 110 begin to play a heat dissipation function. As the operation of the internal components generates heat, the fan 110 prompts air to flow out from the rear ventilation slots 109 to form a heat dissipation channel to maintain a suitable internal temperature environment and ensure the stability of the performance of each component. The cabinet door 101 and the observation door 112 remain closed to ensure the internal closure, but the operator can observe the internal situation through the primary window 106 and the secondary window 111. At the same time, the identification plate 105 provides basic information about the equipment, and the metering power The voltage transformer 201 and the metering current transformer 202 start working and make initial measurements of the input voltage and current. The transformer oil in the transformer oil barrel 203 is in a stable state. The oil level transmitter 208 starts to detect the oil level to ensure that the oil level starts within the normal range. The power display 204 shows that the device is not powered. The thermometer 210 starts to measure the initial temperature. The oil temperature controller 205 monitors the oil temperature and is ready to adjust according to the temperature change. The metering voltage transformer 201 and the metering current transformer 202 continue to accurately measure the voltage and current. These measurement data are transmitted to the buzzer controller 206. The electromagnetic balance winding 211 located at the top of the transformer oil barrel 203 adjusts the phase relationship between the current and voltage according to the analysis results. Through the electromagnetic balance principle, it changes the distribution of current and voltage, thereby reducing the transmission and loss of reactive power and realizing the power saving function. In this process, the electromagnetic balance winding 211 generates a specific electromagnetic field, which interacts with the electromagnetic field in the system to optimize the transmission and utilization of electric energy. The thermometer 210 monitors the internal temperature of the device in real time, especially the temperature near the transformer oil drum 203. If the temperature rises, the oil temperature thermostat 205 will detect the change. When the temperature reaches a certain threshold, the oil temperature thermostat 205 will control the fan 110 to increase the speed and accelerate the flow of air through the rear ventilation slot 109 to enhance the heat dissipation effect. The oil level transmitter 208 continuously monitors the oil level in the transformer oil drum 203. If the oil level drops to Dangerous level may trigger the buzzer controller 206 to alarm, reminding the operator to add transformer oil in time to ensure the normal insulation and heat dissipation function of the transformer oil barrel 203. The multiple groups of insulating columns 209 installed on the secondary mounting frame 302 continue to provide insulation protection during the operation of the device to prevent leakage or short circuit between components with different potentials, ensuring the safe operation of the device under high voltage environment. The live display 204 displays in real time whether the device is energized, providing intuitive safety prompts for the operator to prevent misoperation. The operator can observe the internal situation through the primary window 106 on the observation door 112. At the same time, the information displayed by the live display 204 and the thermometer 210 can be clearly seen through this window.

[0030] Through the above steps, the outer shell 1 wraps the power-saving component and the installation component inside to play a protective role. It can prevent external dust, moisture, etc. from entering the inside of the device, avoid the degradation of the insulation performance of the electrical equipment or short circuit due to dust accumulation, and reduce the power loss caused by these factors. At the same time, the outer shell 1 can also play a certain shielding role for the internal components, reduce the impact of external electromagnetic interference on the power-saving component, and help improve the power-saving efficiency of the device. The installation component is installed inside the outer shell 1 to provide support for the power-saving component. It can ensure that each component in the power-saving component is in a stable working position. The stable installation helps to reduce the vibration or displacement between the components. The electromagnetic interference generated can be improved, and the accuracy of measurement can be improved, which in turn helps to more accurately adjust the current and voltage phase relationship to reduce reactive power loss and achieve better power saving effects. The oil temperature thermostat 205 can monitor the oil temperature in the transformer oil barrel 203. When the oil temperature is too high, it may affect the performance of the electrical equipment in the device, resulting in increased power loss and the possible consequences of transformer burning due to current overload. Through the monitoring of the oil temperature thermostat 205, measures can be taken in time to control the oil temperature, avoid reducing the power saving efficiency of the device due to excessively high oil temperature, and eliminate the risk of burning caused by current overload, thereby ensuring that the device operates in an efficient state and achieving both safety and energy saving.
