Abstract
The invention relates to the high-voltage power supply field, particularly to a high-voltage electricity saving system. A high-voltage input terminal is connected in series with a three-dimensional rolling-iron-core auto transformer; an output terminal of the three-dimensional rolling-iron-core auto transformer is a multi-tap voltage regulator exciting winding provided with a plurality of gears; each gear output is connected with a switch; and each switch is connected with a control chip. With the mutual balancing effect of three phases of the three-dimensional rolling iron core in terms of magnetic potentials, voltages transmitted to electrical equipment can be balanced and stabilized, thereby achieving an objective of power saving. Meanwhile, different gears are selected and thus different voltages are outputted, so that the electrical appliance can work with a minimum proper voltage and thus the energy is saved effectively. Moreover, because of series connection of the three-dimensional rolling-iron-core auto transformer, the stability and filtering of the system are enhanced and the power factor of the system is improved.
Description
Technical field
The present invention relates to high voltage supply field, specifically a kind of high pressure power saving apparatus.
Background technology
High voltage electric is very ordinary in life, and how effectively to save electricity is the something highly considered, economize on electricity is at present general all for low-pressure field, and concrete utilization is little to high pressure field.
Summary of the invention
Technical problem to be solved by this invention is: how effectively to save high voltage electric.
The technical solution adopted in the present invention is: a kind of high pressure power saving apparatus, high voltage input terminal is connected a three-dimensional winding iron core autotransformer, the output of three-dimensional winding iron core autotransformer is tap changer excitation winding more than, many tap changer excitation winding has multiple gear, each gear exports and connects a switch, each switch connection control chip, many tap changer excitation winding connects electrical appliance, control chip is mounted on the power detection device on electrical appliance, the changed power situation that control chip detects according to power detection device, the opening and closing of control switch, electrical appliance is run under minimum suitable voltage, gear refers to the winding of different coil number, high voltage input terminal and many tap changer excitation winding of three-dimensional winding iron core autotransformer use same three-dimensional winding iron core.By the unlatching of control chip control switch, when appliance starting, use the gear that output voltage is the highest, in normal work, the lower gear of output voltage is automatically switched to according to behaviour in service control chip, electric energy can not only be saved like this, nor easily burn electrical appliance, control chip is mounted on the power detection device on electrical equipment, different switch is opened according to changed power on electrical equipment, electrical appliance is run under minimum suitable voltage (the minimum voltage that the gear that can meet electrical appliance power needs exports), when namely power rises, select high output voltage, during power drop, select low output voltage.The high pressure mentioned in the technical program refers to that 320-450 lies prostrate three-phase alternating voltage.
As a kind of optimal way: all gear output voltages of many tap changer excitation winding are 90% high input voltage terminal voltage ~ 110% high input voltage terminal voltage.When starting electrical appliance, voltage needs higher, or when electrical equipment uses interruption to need discontinuity high voltage, automatically switches to suitable gear, not only meet electricity consumption needs but also can save electric energy by control chip.
As a kind of optimal way: gear has five, the high input voltage terminal voltage of corresponding output 97%, 96%, 95%, 94%, 93%, or corresponding output 97%, 95%, 93%, 91%, 89% high input voltage terminal voltage, or the high input voltage terminal voltage of corresponding output 95%, 93%, 91%, 89%, 87%.General electrical equipment needs higher voltage when starting, the lower voltage of stable rear maintenance one just can meet energy-conservation needs, corresponding five gears of the present invention, the different gear that automatically switches can be selected according to the needs of electrical appliance, only need set in the chips switching condition just can, effectively can save electric energy.
In the selection of above gear of the present invention, be that the gear that can meet most of electrical equipment needs is at present selected, but the present invention has not limited to above gear to be selected.
What express in foregoing is all stablize for input, reduce output end voltage thus the problem of economize on electricity, in fact, the technical program is also suitable for input terminal voltage change (such as: user is powered by 380 volts of three-phase alternating currents, time by day, input terminal voltage is low, and during evening, input terminal voltage is high), require that all gear output voltages are 90% high input voltage terminal voltage ~ 110% high input voltage terminal voltage this time.If be still five gears, but the high input voltage terminal voltage of corresponding output 90%, 95%, 100%, 105%, 110%, and gear needs according to specifically selecting.When input terminal voltage is lower, if the minimum essential requirement voltage (the minimum voltage that the gear that can meet electrical appliance power needs exports) of electrical appliance can not be met, just need to heighten voltage by gear, when input terminal voltage is higher, be adjusted to minimum suitable voltage by gear just can, minimum suitable voltage refers to the minimum voltage that can meet electrical appliance demand, this voltage can be determined by the voltage measured on electrical appliance, first the minimum operating voltages minimum operating voltages set point the most on electrical appliance is determined by experiment, then the moment detects the voltage on electrical appliance, if detect that virtual voltage on electrical appliance is in decline state close to minimum operating voltages set point, voltage then during adjustment gear on electrical appliance raises, until voltage constant on electrical appliance and close to minimum operating voltages set point, this value is minimum suitable voltage, if detect that virtual voltage on electrical appliance is in propradation higher than minimum operating voltages set point, voltage then during adjustment gear on electrical appliance reduces, until voltage constant on electrical appliance and close to minimum operating voltages set point, this value is minimum suitable voltage.
The invention has the beneficial effects as follows: high voltage input terminal is connected a three-dimensional winding iron core autotransformer, utilize excitation balance mode and the design feature of three-dimensional winding iron core, reach mutual balanced action in magnetic potential in three-phase, the voltage flowed on power consumption equipment is balanced and stablizes thus reach the object of power saving, simultaneously by selecting different gears, and then export different voltage, electrical equipment is run under minimum suitable voltage, effectively save the energy, due to series connection three-dimensional winding iron core autotransformer, serve the effect of current-limiting reactor, surge can be absorbed, thus sluggish heavy current impact, minimizing system instantaneous pressure drop, improve the stability of a system, and serve the effect of filtering, improve the power factor of system.
