Description
Technical field
The invention belongs to electronic technology and be combined the field with power technology, relate to a kind of energy-saving device, particularly a kind of three-phase electricity-saving device.
Background technology
In terminal use's electrical network, exist a large amount of winks stream, and wink stream be a kind of transient distortion of electric current and voltage in the sine wave AC circuit, surge and harmonic wave are its main form of expression.The main feature of distortion is superhigh pressure, ultrahigh speed, the superelevation frequency.Superhigh pressure: refer to that 2-50 that wink stream spike exceeds the normal voltage amplitude doubly.Ultrahigh speed: refer to flow in wink spike and occur in the extremely short time.The superelevation frequency: refer to that the wink activity of stream spike is very frequent.
We can say and wink flow at all times, ubiquitous.The source that the wink miscarriage is given birth to mainly contains two aspects: the one, and external environment condition, as: lightning induced voltage, the large-scale switch in power transmission and transformation station close jumping, the start-stop of contiguous enterprise bulk loads, the capital has wink stream to enter into using electricity system, and the 2nd, the inner wink stream that produces of using electricity system, as: close and sudden load change the frequent pass of any load, arc discharge all can have a large amount of wink miscarriages to be born in the using electricity system of itself, and has influence on contiguous enterprise and electrical network.Because wink stream existence, copper loss, iron loss, the line loss of inductive load are increased, the consumption that has not only increased electric energy also causes the extra temperature rising of power consumption equipment and makes various contacts produce oxide layer and loose contact that its consequence is to use the family to increase the electricity charge and shortens the useful life of power consumption equipment.
At present, the battery saving arrangement that generally uses all is the electricity-saving appliance that adopts the third generation in the world, this electricity-saving appliance is a kind of converter plant of tandem type, it must be cascaded with each power consumption equipment respectively, can there be several defectives in this mode: the first, and the user need change operating habit and the power mode of electricity consumption; The second, if the converter plant of this tandem type breaks down, user's equipment can't normally be moved, and influence ordinary production, so must carry out manual intervention; The 3rd, the converter plant of this tandem type not only self power consumption is bigger, and complex circuit, not only break down easily, and, user's input cost height, and the maintenance cost in later stage is also higher, causes economic benefit not high.
Summary of the invention
Above-mentioned existing change consumption habit, failure rate height, power consumption are big in order to remedy, complex circuit, economic benefit are low, input and the high deficiency of maintenance cost, the invention provides a kind of three-phase electricity-saving device, and it has following six advantages:
One, it is a kind of battery saving arrangement of parallel connection type, and a user only needs in total outlet of its transformer the power savings that can realize ideal to be installed;
Two, the user does not need to change operating habit and the power mode of original electricity consumption, and accomplishes non-maintainingly substantially, will withdraw from automatically if it breaks down, and does not influence the normal operation of subscriber equipment;
Three, it is by absorbing in terminal use's electrical network because the frequent variations of electric load, the start-stop folding of perception equipment and the wink stream, surge, the harmonic wave that produce, convert it into and be useful sine wave, improve the reduction supply waveform, increase and realize economize on electricity for power consumption efficiency;
Four, it utilizes computer chip that wink stream and harmonic wave deal and user load are carried out real-time analysis, calculating, tracking, regulation and control reaching high accuracy, high efficiency economize on electricity, and has effectively eliminated the infringement to electrical network and power consumption equipment such as wink stream, surge, harmonic wave;
Five, it can also reduce the distortion degree of voltage and current in economize on electricity, purifies electricity supplying and using system, improves the antijamming capability of power consumption equipment, improves the quality of power supply of whole system, prolongs the Acceptable life of power consumption equipment;
Six, it is not only simple in structure, and the cost that drops into is low, and its power saving rate can remain between 5%～20%; In some type of production enterprise, if the inductive load of the power consumption equipment of these enterprises changes greatly, it just can reach the best power savings of economize on electricity more than 20% so.
Therefore, it have novel structure, easy and simple to handle, easy for installation, cost is low, economic benefit is obvious, failure rate is low, antijamming capability is strong, power savings is good, the characteristics of power conditioner, protection equipment.
