Description of the invention (/) [Background of the invention] a. Field of the invention: The present invention relates to a method and device for improving equipment efficiency and power saving, especially Equipment load factors are different and the voltage is adjusted appropriately in order to seek the best efficiency of the equipment itself and achieve the power saving effect. b. Prior technology: First press, progress of civilization, increasingly advanced technology, all due to the invention of electric energy, but the resources to produce electric energy such as coal, oil, natural gas, nuclear energy, etc., have increased in cost, and they will eventually run out. Although some of the electricity is converted by solar energy, it is not a resource that can completely replace the existing electricity. In addition to the increasing use of electrical energy by human beings, in addition to the construction of power plants, industrial equipment and consumer electronics are now moving towards the design of low power consumption and how to manufacture or develop equipment and methods that can save energy is the goal pursued by the industry. For the second press, the current electricity cost is calculated as KWH = VI COS 0; where KWH = total real power, which represents the calculation formula for electricity cost V = voltage 1 = current COS0 = power factor. The current commonly used power saving methods are analyzed one by one as follows: I. Improving the power factor Is it beneficial to the user to increase the power factor? The increase in power factor will offset the effect of VI reduction, but the power company will take the power factor into account when calculating the electricity fee. When the power factor is greater than 0.8, the electricity fee may be based on the actual power _ page 3 __ a paper scale Applicable to China National Standard (CNS) Λ4 specification (210 × 297 mm) ~ 1 '" ~ (Please read the notes on the back before filling this page) 577990 A7 B7 V. Description of the invention (j) (Please read the notes on the back first Please fill in this page again) Factor deduction, when the power factor is less than 0.8, you need to bear more electricity costs. Therefore, if the user's power factor can be improved, although the gastric rate used can not be reduced, or even reduce blood pressure Part of the effect of the operation, but it can still be reduced by the reduction of electricity: the cost is compensated; in addition, the benefits of improving the power factor still have the advantages of increasing the design _ utilization rate, reducing line losses, etc., but this method is Its use is very limited and generally can only be used as an auxiliary. Second, the method of voltage reduction using a step-down transformer or other electronic components that can achieve voltage reduction of the structure directly reduced voltage, the effect is simple and obvious, especially for fluorescent lamps, but the disadvantage is that when the power company supplies the Voltage, if the peak voltage, the supplied voltage is often low. Using the voltage reduction method, it is easy to cause the voltage to be too low, and the equipment cannot be started or the efficiency of the equipment is deteriorated, and it consumes more power. It's quite limited. Third, the method of voltage stabilization Printed by the Consumer Property Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is to improve the direct voltage drop due to the excessively low voltage supplied by the power company. However, for general electric, inductive motors, compressors and other equipment, often due to the moment of starting or when used to full load, if it is stabilized at a voltage lower than the rated voltage of the equipment, it will cause the equipment to perform its work. If the efficiency is not achieved, the current used will be too large, which will not achieve the effect of power saving, and even consume more power. The so-called "work efficiency" here refers to the value of the equipment to perform work, such as pressure, torque, speed, etc. “Equipment efficiency” means that the minimum work efficiency is achieved with the lowest KWH value.

Method of changing the frequency-general electric motors will use changes The frequency is used to reduce the speed to achieve the purpose of stomach. At present, only devices such as reducing the speed without affecting the efficiency (such as the power (1)) are commonly used in AC motors, and the work efficiency must be fixed. If work is performed, Efficiency is variability, so this method is not feasible. Press again, the current power-saving equipment can only be used for resistive loads, such as lighting _ 较 and other more effective, but for power-hungry equipment such as air conditioners, ice water machines, there is still no better way to save power . According to the law of constant energy, when a device is used to the limit of work efficiency (100 ° / 〇, no matter what method is used, there is no room for power saving. On the contrary, when the device has the maximum work efficiency, it is necessary to provide A rated voltage value can achieve this purpose. So we get a verification that all the inductive, electromotive and other characteristics of the equipment, when the load rate is the limit of the equipment, there is almost no room to save electricity, otherwise, That is, there is room for improvement in efficiency and power saving. Therefore, for some equipment that has seasonal, temporal or special environments, and the load rate is often below a certain ratio, you can seek the best efficiency of the equipment itself and achieve power saving. The effect is the problem to be solved by the present invention. [Objective and Summary of the Invention] The main purpose of the present invention is to provide a method and device for improving equipment efficiency and power saving, so that a device is moderate according to different load rates. Those who adjust the voltage and improve the power factor in order to seek the best efficiency of the equipment itself. Yet another object of the present invention is to provide a method for improving equipment efficiency.

Description of the invention (?) The data in the three figures are based on the appendix 1: Induction motor characteristic test record table. The data measured at different load rates and voltages are: Commercially available Dongyuan LOOHP, Type: AEEF motor test, please refer to it, and will not repeat it. In addition, the capacitor compensation device (36) of the present invention can timely compensate the capacitance of the voltage adjustment mechanism (31) to improve the power factor of the equipment and increase it to a higher level to reduce the line loss and the voltage drop of the instantaneous starting current. Please refer to the fourth figure again, which is a comparison table of voltage changes and power consumption. The present invention uses an experimental data to explain how to improve efficiency and power saving. The fourth figure is that the motor speed is constant at 1710rpm, when the voltage is 220V full load When the torque is 0.4 26 (kg-m), the current value is 3.13 (A), the input power is 9 40 (W); when the torque load is only 0.362 (kg-m), the current is measured. The value is 2.8 1 (A), the input power is 775 (W), so the corresponding optimal voltage value is 2 00 (V), that is, the microcomputer processor (3 5) makes the voltage adjustment mechanism (31) adjust the voltage value to 200V Send it to the equipment (motor) to get the power saving and efficiency improvement. Because the load rate of general motors is mostly below 50%; therefore, there is room to apply the present invention to achieve the desired efficiency increaser. Of course, if you look at the data sheet in the third figure, Rong may question that there seems to be no room to save power and improve efficiency when the load rate is 75% or 100%; however, the data sheet in the third figure is completed in the laboratory. The standard voltage is set to 220V; however, when the equipment is actually in use, the voltage supplied by the power company varies greatly during the off-peak period, some as high as 240V when the peak is off, and some as low as 190V during the peak; therefore, it is not completely There is no space for power saving, even if the power saving efficiency is not high at a high load rate, the invention can still be used as a voltage regulator under such a situation that the mains supply voltage changes greatly.
