Embodiment Construction

[0023] Taking the low-voltage fully intelligent power saver (below 500V) as an example, the composition and implementation of the power saver will be further described in conjunction with accompanying drawings 3 and 4.

[0024] (1) The circuit structure is to make the power saver more concise, practical and cost-effective. Its signal collector is composed of light-emitting diodes and photosensitive resistors as the main components. On the other hand, the output current required by the internal voltage source of the low-voltage power saver is not very high. Large, so the internal demand voltage source does not need to set up the transformer transformation link. This power saver is composed of the following parts: ①Signal acquisition part: the light-emitting diode D1 is connected in series to the branch circuit L1 of the incoming line end, and D1 acts on the photosensitive resistor R1, which is composed of photosensitive resistor R1, resistor R2 and single-chip control signal H1 ...

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. Technical field [0001] The invention is used for reactive power compensation of industrial and household electrical equipment and elimination of 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 on 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 difficult maintenance. , making it difficult to popularize the main method of power saving "reactive power compensation" technology; The effect is not very satisfactory, and it has become the main reason why household appliances are difficult to be widely used; and electricity saving is an urgent need of enterprises, families and society, especially in the current situation of energy shortage and high en...
