Problems solved by technology

However, due to the large reactive power consumption in the starting process of the iron core magnetic ballast, the power factor is generally only 0.35 to 0.55, and its apparent power remains high. Due to the large amount of use and the wide area, the waste of electric energy is very alarming.

Abstract

The feature of the invention is: the input end of low voltage power supply is connected with mains supply and its output end is connected with the input end of waveform shaping circuit, and supplies power to each circuit except timer through self keeping power switch; the power of timer is supplied by stabilized voltage power, and its output end is connected with the control end of self keeping power switch; the output end of waveform shaping circuit is connected with the triggering input end of bi-stable model circuit; the output end of bi-stable model circuit is connected with the voltage control end of bi-stable model circuit is connected with the triggering input end of astable model circuit; the voltage control end of astable circuit is connected with output end of slowly increasing voltage control circuit; the astable circuit processes the output signal outputted by bi-stable model circuit and control signal output by slowly increasing voltage control circuit, and sends them to the triggering control end of synchronous phase-shift circuit; after the synchronous phase-shift circuit is serial connected with compensation capacitor, its both ends are connected in parallel with mains power and then is connected with halogen lamp.

Description

technical field [0001] The invention relates to an energy-saving switch device for electric equipment requiring soft start, in particular to an energy-saving switch device for soft start. Background technique [0002] In order to ensure that the equipment will not be damaged or affect its service life due to the influence of starting current and voltage, and at the same time achieve the purpose of saving energy, various existing electrical equipment, especially high-end electrical equipment, are designed with soft-start protection switches. There are generally two types of soft start protection switches: electronic type and frequency conversion type. They all have the disadvantages of complex circuit, high use requirements, short life, high cost, large energy consumption, and poor versatility. [0003] For example, the iron-core magnetic ballasts matched with gas discharge lamps (that is, metal halide lamps) have the advantages of simple structure and less failures, so this ...
