After equipment of the present utility model is mainly used in the output of three-phase alternating current power supply, make the electricity consumption user can save a kind of equipment of electric energy.This equipment,
1. why can drop-out current? can save the electricity charge?
At line end installing energy conserving system, thereby be that electromagnetism that load is produced does not have function and closely absorbs the back and change useful active energy into by energy-saving equipment and reduce line current for the demand that electric can reduce load power source once more.As everyone knows: the electricity consumption electric current is big more, and the electricity charge are many more, and electric current has just reduced the electricity charge after descending.
2. but burning voltage why? can save the electricity charge again?
According to: the P=UI gained, bearing power is certain, and load will reach identical power, produce voltage drop because of line loss again, must increase loop current, after the installing energy-saving equipment, just can reduce to minimum to this part line drop, U road=U is total-and U decreases, after wire-end voltage got a promotion, as long as reach equal power, load circuit stream just can correspondingly reduce, stablize the wire-end voltage of load simultaneously, therefrom also just can save electric energy.
