Description
Technical field
The utility model relates to a kind of device that reduces idling consumption.
Background technology
Transformer is an important component part of many electrical equipment or equipment, and many times electrical equipment or equipment are in underloading or unloaded state, thereby the loss during standby has accounted for a sizable part in the middle of energy consumption, waste huge.
Although no-load loss only accounts for about 1/6～1/4 in the total losses power of electrical equipment and equipment, but from circadian energy loss, its shared ratio is but not little, especially the transformer of some low load factors, stand-by time is longer, and the influence of no-load loss is just more outstanding.
Summary of the invention
Loss when the utility model will solve electric appliance standby has accounted for the problem that a sizable part causes huge waste in the middle of energy consumption, a kind of device of saving the reduction idling consumption of the energy is provided.
The technical solution of the utility model:
A kind of device that reduces idling consumption, comprise AC power and transformer, described transformer is connected with AC power, it is characterized in that: be provided with sectional pressure element between described transformer and the AC power, described sectional pressure element is parallel with a switching circuit, described switching circuit is connected with electronic control module, described electronic control module input load status signals control switch state.
Further, described sectional pressure element is that impedances such as resistance or electric capacity constitute.
Further, described electronic control module is relay or triode or optocoupler control circuit or SCR control circuit.
Transformer is as a decompression device of electrical equipment or device interior, a primary coil and one or more secondary coil are arranged, primary coil is connected on the AC power, when electrical equipment is in holding state, the load of the secondary coil of transformer is very light, even unloaded, so can come approximate analysis, see Fig. 1 with zero load.
Because the primary coil of transformer is connected on the AC power, so no-load loss always exists, the variation with load does not change, often think constant loss, comprise the copper loss on magnetic hysteresis loss, eddy current loss and the coil resistance of transformer, and when unloaded, the loss of transformer is mainly magnetic hysteresis loss and eddy current loss, i.e. the iron loss of often saying.
The magnetic hysteresis loss of transformer also is directly proportional with the quadratic power of magnetic flux density except relevant with permeability magnetic material; The eddy current loss of transformer also is directly proportional with the quadratic power of magnetic flux density except outside the Pass the frequency with the thickness of permeability magnetic material, power supply has, and like this, on the basis of current material, the no-load loss of transformer is directly related with magnetic flux density.
Suppose that supply voltage is U
1, if ignore the resistance drop and the leakage reactance pressure drop of primary coil, then the induced potential E of primary coil
1Have: E
1≈ U
1Wherein:
E
1＝KfBm
K---proportionality constant, long-pending relevant with the number of turn and the core section of primary coil;
The frequency of f---supply voltage, the Hz of unit;
Bm---the peakflux density in the iron core, unit Wei/rice
2
Magnetic flux density in the iron core of primary coil is determined that by induced potential the no-load loss size is by the voltage swing decision of primary coil thus.
The utility model when the transformer operate as normal, described electronic control module control switch closure, the voltage of transformer equals supply voltage, electrical equipment or equipment can normally move; When electrical equipment or equipment were in holding state, described electronic control module disconnected according to the load state Signal-controlled switch, and the voltage of transformer reduces, and idling consumption reduces, and energy consumption also just reduces.
Advantage of the present utility model: simple in structure; realize easily; can reduce 10～20% of idling consumption; not only reduce the electricity charge; save the energy; also reduced the investment cost of a power transmission and transforming equipment, and power plant is that the multiple electricity of loss is given the expense that influence that environmental protection brings and environment protection treating increased etc.
