And the K1 among Fig. 1 is an air switch, and K is a regular tap, and M is a motor.
After the utility model technical equipment of the patent 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, produces 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 always-U decreases after wire-end voltage gets a promotion, as long as reach equal power, load circuit stream just can correspondingly reduce, and has stablized the wire-end voltage of load simultaneously, therefrom also just can save electric energy.
3. why line loss is arranged, how does line loss form? can make line loss improve several points after loading onto energy-saving equipment?
Resistance is the conductive characteristic that material itself has, generally speaking, the resistance value of metallic conductor raises with temperature and increases, when the link tester overcurrent, reason owing to electric resistance partial pressure, will produce pressure drop at the circuit two ends, this part pressure drop is transformed into heat energy loss to electric energy in circuit acting back to be fallen, thereby has just formed line loss.Line loss rate is length, the line footpath according to distribution, the size and the electric current of load power consumption, because of above 3 be parameter, the proportion of goods damageds that cause are and variant, definite data should be as the criterion with in-site measurement calculating.
4. improve the benefit of power factor?
Improving power factor also is to save one of electricity consumption project.The purpose of improving power factor is exactly in order to improve the service efficiency of electric energy, and the KVA gap of power KW that electric energy is done and system supply reduces, and the efficient of power electric energy is high more, that is the inefficient power KVAR of system supply reduces, and then plays the gap of KW and KVA and gets over ripple.Power factor is low, and the expression inefficient power is bigger than normal, and line current is increased, and increases the power loss of circuit and power consumption equipment.Desire improves the power consumption efficiency factor, must reduce the inefficient power KVAR of system supply.Therefore, the employing automatic power factor regulator is adjusted the KVAR that works as in good time and is measured, and more can maximum benefit get energy savings, reduces production costs, and reduces equipment maintenance cost, the long service life of equipment in the court of a feudal ruler, and the reduction circuit consumes, and keeps the balance of voltage source.Stable power is supplied with, power system capacity is increased, reduce high order harmonic component, effectively suppress wink stream, surge, the building-out section electric work is imitated. and power savings is obvious, guarantees power saving rate 8%-18%, alleviate electricity charge burden. increase the allowance of transformer, promote effective power consumption, electric current reduced, improve and burning voltage.
Based on former technical description and present technical characterstic: using frequency converter in the past, is to change the power consumption equipment frequency, increases the operating efficiency of motor, increases output, but long-term the use useful life that can influence power consumption equipment.
Now, the utility model is comprehensive high-effect electric power energy-saving equipment, more once, frequency converter is different with the position that comprehensive high-effect electric power energy-saving equipment is installed, frequency converter is mounted on the machine, and the comprehensive high-effect electric power energy-saving equipment of the utility model is mounted on the circuit of whole electricity consumption.And the digital automatic Regulation and reactive power compensation circuit of energy triple-frequency harmonics filtering line group, and the digital control system of microcomputer with the filtering of LC frequency-modulated wave.
