Embodiment Construction

[0049] The working principle diagram of the present invention is attached figure 1 As shown, among them, the normally open contact of the power-saving contactor is K j , the normally open contact of the bypass contactor is K p , K 1 …K n It is the normally open contact of the power-saving gear contactor, K 1 '... K n ' are the normally open contacts of the gear auxiliary buffer contactor respectively. R, C parallel circuit is gear buffer, L 1 is the total inductance of the power-saving coil group, and the symbol of the remaining inductance is L 2 , L 1 ', L', L 1-2 The representative inductance has been marked in detail in the drawings and will not be described again.

[0050] attached figure 1 In , when the grid AC voltage acts on the device, the energy-saving device automatically adjusts its working state according to the change of the grid voltage amplitude. When the grid voltage is high, the power saving device works in the power saving state, and which power ...

Abstract

The invention discloses a lighting energy saving device with no flash or overvoltage on the basis of logic control, and a control method thereof. The lighting energy saving device comprises an energy saving switch which is successively connected with a fixed energy saving coil and an energy saving coil set in series, wherein the energy saving coil set comprises at least two energy saving tap position coils successively connected in an energy saving circuit in series; the tail end of each energy saving tap position coil is electrically connected with a zero line respectively by an energy saving tap position control switch and is also electrically connected with a tap position assistant buffer control switch; all tap position assistant buffer control switches are electrically connected withthe zero line by a tap position buffer; two ends of the energy saving coil set are connected with load; and a bypass switch is arranged between the live wire end of mains supply and the tail end of the fixed energy saving coil. The invention automatically adjusts power supply state according to the fluctuation of power grid voltage, does not generate overvoltage impact in the state conversion process, does not generate voltage flash and electric arc phenomena and ensures the reliability of load power supply.

Description

technical field [0001] The invention relates to a power saving control device, in particular to a lighting circuit conversion device from power saving to bypass direct connection. Background technique [0002] With the rapid development of China's economy and the continuous improvement of the degree of industrialization, people's living standards have also been continuously improved, and new requirements have been put forward for lighting equipment and lighting projects. Lighting projects have become a symbol of urban civilization. In the promotion of urban lighting projects In the process, lighting sources and control equipment have been developed unprecedentedly, and the power consumption and various power consumption of urban lighting are also increasing. Therefore, the development and promotion of efficient and reliable lighting energy-saving devices are in line with my country's national policy and also It has important social and economic significance. [0003] The fund...
