Embodiment Construction

[0023] The following is an example of a low-voltage all-intelligent power saver (below 500V), combined with the attached image 3 and attached Figure 4 The structure and implementation of this power saver will be further described.

[0024] (1) Circuit structure In order to make the power saver more concise, practical, and lower in cost, its signal collector uses light-emitting diodes and photoresistors as the main components. Therefore, the internal demand voltage source does not need to set up the transformer transformation link. This power saver consists of the following parts: ①Signal acquisition part: LED D1 is connected in series on the branch L1 of the incoming line, D1 acts on the photoresistor R1, which is composed of the photoresistor R1, the resistor R2 and the single-chip control signal H1. The circuit samples the incoming line current and provides incoming signal N1 to the single-chip microcomputer; the light-emitting diode D2 is serially connected to the load-...

Abstract

The invention relates to a compensation apparatus reactive power full intelligent energy-saving equipment, which is composed of a signal collector, a center control circuit, a compensation circuit, a power grid surge eliminating circuit as well as an internal voltage source. The invention connects a controlled source in series beside a compensation component of the compensation circuit, and finally makes the compensation circuit provide the burdened reaction power by applying the compound control technology of the central control circuit to the controlled source. Features the simple and practical structure and high energy-saving efficiency, the technology totally solves the problems of the large volume and high cost of the current energy-saving equipment in the market, is able to enhance the power factor to 0.95 above, and meanwhile, realizes the intellectualized control.

Description

1. The technical field [0001] The present invention is used for reactive power compensation of industrial and household electrical equipment and elimination of power grid surge and high-order harmonic interference, thereby realizing high-efficiency power saving for users. 2. Background technology [0002] At present, the price of industrial reactive power compensation equipment in the market is generally high. A set of compensation equipment can range from tens of thousands to millions. Only a few large enterprises can purchase it, and there are still problems such as large equipment size and difficulty in maintenance. , making it difficult to popularize the technology of "reactive power compensation", the main method of power saving; on the other hand, in the market of household electrical appliances, such products are mostly primary products that eliminate power grid surge and high-order harmonic interference, saving power The effect is not very satisfactory, and it has be...
