Intelligent power-saving equipment with contactless adjustment function

Abstract

The invention relates to intelligent power-saving equipment with a contactless adjustment function and relates to the technical field of power distribution systems. The equipment comprises a clampingblock, and a flange block is fixedly connected to the front surface of a mounting ring. The intelligent power-saving equipment with the contactless adjustment function integrates advanced alternatingcurrent voltage regulation technologies such as a transformer winding combination and a contactless switch, and has the characteristics of high efficiency, quick adjustment, no mechanical moving part,high reliability, long service life, wide application range and the like. The transformer windings are selected in a combined manner, and more voltage regulation gears are realized by using a small number of self-coupling windings, so that self-coupling winding resources can be fully utilized, and the voltage stabilization precision is relatively high. The single-chip microcomputer compares the calculated theoretical value of the output voltage curve at the moment with the detected actual value of the output voltage, and the output voltage can be stabilized on the working curve through the contactless switch. The contactless switch works in a full-cycle waveguide conduction state, no additional harmonic wave is generated, and the contactless switch is a real green power supply product.

Description

technical field [0001] The invention relates to the technical field of power distribution systems, in particular to an intelligent power-saving device with a non-contact adjustment function. Background technique [0002] The bidirectional thyristor non-contact adjustment is applied to the power-saving equipment of the power distribution system, which has no pollution to the power grid, and the shift transition time is microseconds, which is thousands to hundreds of times faster than the contact shift transition time of commonly used AC contactors. ten thousand times. Therefore, it can be achieved that the main circuit voltage and current have no interruption, no current impact, and no overvoltage phenomenon when shifting gears. Its advantages are very obvious. The highly reliable intelligent energy-saving equipment with non-contact adjustment technology can achieve an adjustment accuracy of ±1%, a maximum energy-saving rate of more than 20%, and can greatly extend the servi...

Problems solved by technology

The main reason is that the key technology of product shifting has not passed the test. Theoretically speaking, under the inductive load, as long as the quality of the non-contact device passes the test, as long as the key technology passes the test, the life of the non-contact product must be longer than that of the contact product. Many, if using contact products or non-contact products that have not passed the key technology, the complex and changeable grid interference signals cannot be accurately detected and judged, which will lead to poor reliability of the product
