Description

A kind of electricity-saving appliance

Technical field

The utility model is related to energy-saving device, and in particular to a kind of electricity-saving appliance.

Background technology

With gradually increasing for terminal use's power grid electric, if it is user's very concern to improve power grid quality. In terminal use's electrical network, there is a large amount of winks stream, wink stream be that electric current is abnormal with a kind of transient state of voltage in sine wave AC circuit Become, wink stream the copper loss of inductive load, iron loss, line loss can be caused to increase, the consumption that not only increased electric energy also causes electricity consumption The additional temperature of equipment is raised and makes various contacts produce oxide layers and loose contact, and its consequence is user is increased the electricity charge and is contracted The service life of short electrical equipment.Generally using dash current, the transition in electricity-saving appliance suppression and reduction supply line on market And the generation of higher hamonic wave, power conditioner, the power supply quality of raising electrical network, the copper loss of line loss and power-equipment is greatly reduced And iron loss, to improve the service life and mechanical efficiency of electrical equipment.But in existing electricity-saving appliance, some system complex, investment is big, Later maintenance cost is higher；Some regulations are inconvenient, and user need to change the operating habit and power mode of electricity consumption；Have to electrical network Additional electromagnetic pollution can be produced, making the power supply quality of electrical network reduces.
