Abstract
The utility model discloses a mini energy saving transformer. The product is connected in series with a line of a watt-hour meter, and the mini energy saving transformer comprises a power supply voltmeter V1, a load voltmeter V2, windings L1 and L2, an iron core B, capacitors C1 and C2, capacitor switches K1 and K2, and a safety tube. When the voltage is overhigh, the mini energy saving transformer operates the function of pressure-limiting by windings L1 and L2 and the iron core B ; when the voltage is over low, the voltage can resumed to normal supply by compensating the voltage of capacitors C1 and C2 . The mini energy saving transformer has simple product structure and stable performance, and the mini energy saving transformer is an ideal mini energy saving transformer.
Description
Technical field: the utility model relates to a kind of transformer, particularly relates to a kind of miniature energy-economic transformer.
Background technology: in China because vast in territory, regional disparity is bigger, country's power supply network is wide, the load peak difference of electricity consumption is very big, make line voltage very stably remain on the power supply of 220V, be difficult to accomplish fully, sometimes more than the voltage Gao Shida 260V, when low below 170V, household electrical appliance are burnt out during electricity consumption under high voltage, household electrical appliance can not normally use again during low pressure, thereby the voltage stabilizing electrical equipment sold on the market occurred, and use voltage stabilizing electrical equipment, only use at single electrical equipment, use face is narrow, and complex structure, power consumption is big, is difficult to adapt to the safe handling of whole home household appliance.
The utility model content: the utility model will provide a kind of simple in structure exactly, and the scope of application is wider, can make the energy-conservation miniature energy-economic transformer of the household electrical appliance energy safety utilization of electric power of whole family.
