Portable household power saver

Abstract

The invention discloses a portable household power saver. The portable household power saver comprises pins and a first capacitor, wherein the pins are connected with a fire wire and a null line, a fuse, a diode, resistors and a second capacitor are serially connected at the rear end of the pin which is connected with the fire wire, the other end of the second capacitor is connected with the pin which is connected with the null wire, one end of the first capacitor is parallelly connected between the fuse and the diode, and the other end of the first capacitor is connected with the pin connected with the null wire. In the portable household power saver, the fuse is arranged to avoid accidental damage caused by instable voltage, the diode and current limiting resistors are arranged to stabilize voltage within a certain range, the first capacitor is arranged to eliminate harmful harmonic wave in a power source, the second capacitor is arranged to realize reactive compensation, and accordingly safety and economy of power utilization are realized.

Description

technical field [0001] The invention relates to a power saver, in particular to a household portable power saver. Background technique [0002] At present, most household appliances are inductive loads, and household appliances will generate some reactive power when they work normally, but too much reactive power will directly affect the power factor, thus wasting electric energy. If household appliances do not receive reactive power compensation, the quality of grid power supply will decline, which will lead to the loss of electric energy. Therefore, it is necessary to develop a reactive power compensation equipment suitable for household appliances. [0003] The defects of reactive power compensators for household appliances currently on the market are: [0004] 1. There is no effective voltage stabilizing circuit, which easily causes household appliances to be subjected to voltage shocks and shorten the service life; [0005] 2. The selection range of the input capacit...

AI Technical Summary

Problems solved by technology

[0004] 1. There is no effective voltage stabilizing circuit, which easily causes household appliances to be subjected to voltage shocks and shorten the service life;

[0005] 2. The selection range of the input capacitor is too large, which may easily cause overcompensation to the electrical appliances with low power, which not only does not save power but consumes more power

[0006] 3. There is no fuse, once the voltage is slightly unstable, it will be permanently damaged
