technical field

The utility model relates to the field of power systems, in particular to an energy-saving power supply and an energy-saving power supply system.

Background technique

With the rapid growth of electricity consumption and electricity load across the country, there are various levels of power shortages and even power cuts in many places every year. According to statistics, lighting electricity consumption around the world consumes about 30% of all power generation. Therefore, saving lighting electricity consumption is of great significance to energy saving, emission reduction, low-carbon environmental protection. However, high-power on-load regulation has always been an international technical problem. At present, lighting energy-saving solutions include direct energy saving and indirect energy saving. Direct energy saving refers to replacing high-energy-consuming lamps with energy-saving lamps, such as LED lamps, energy-saving lamps, electrodeless lamps, etc.; indirect energy saving refers to adding energy-saving controllers or power-saving devices on the line without changing the original lamps. To achieve the purpose of energy saving.

In the prior art, transformer-type energy-saving devices are currently the mainstream devices on the market, and such devices are mostly used in lighting energy-saving renovations. Transformer power saving devices are specifically divided into the following categories:

In the prior art, in order to save electric energy, there is a transformer power saving device: electromagnetic autotransformer fixed tap mechanical switching device: large and heavy, cannot perform on-load voltage regulation and dimming during work, the power saving rate is fixed, and the illuminance cannot be controlled. There is a phenomenon of inversion of illuminance and demand; electromagnetic autotransformer tapped silicon controlled rectifier (SCR) switching device: large and bulky, abrupt voltage regulation and dimming, and the phenomenon of extinguishing the HID lights of urban road lighting. Dimming cannot be precisely controlled, and the failure rate is high due to the common state conduction when multi-SCR switches are switched; the electromagnetic autotransformer stepless carbon brush switching device: it is bulky and heavy, and the mechanical carbon brush components slide under high current, which is affected The impact of electric sparks, short life and high failure rate; electromagnetic induction transformer motor servo stepless carbon brush voltage regulator: large and bulky, low efficiency, and loud noise. This kind of energy-saving device saves electricity but does not save money, the life of the lamp is short, the cost of replacing the lamp and the engineering cost are high, and the voltage is lowered when the lamp is turned on, and it cannot be illuminated on demand. When illuminated, the light gets brighter instead. Such power-saving devices do not conform to environmental protection and sustainable development. They consume a large amount of rare copper and silicon steel, and are seriously stolen and damaged. At the same time, large-scale use will lead to environmental pollution and energy waste.

The SCR control device has a SCR thyristor regulator: the input current has large harmonics, pollutes the power grid, and the output voltage is seriously distorted, causing electromagnetic interference, which cannot meet the requirements of electromagnetic compatibility. At the same time, it can only adapt to inductive lighting loads. And the country's mandatory capacitance compensation cannot adapt. SCR single-lamp power saver and SCR centralized control power saver are relatively stable for energy-saving control of pure inductive lighting systems. The effective value of voltage can be adjusted smoothly in real time and in different periods, and can achieve modular and small embedded control, but the inductive ballast it uses The device requires local compensation or centralized compensation of the capacitance of the lamp. SCR energy-saving products cannot adapt to capacitive loads. A large number of low-order harmonics generated by the sudden conduction of the capacitor to the SCR form a short circuit of the power supply.

Aiming at the problem in the related art that when the control circuit is energy-saving, it is impossible to precisely regulate the voltage of the high-frequency and high-power on-load circuit, no effective solution has been proposed yet.
