Technical field
The present invention relates to high voltage supply or power transmission and distribution field, specifically a kind of high pressure power saving apparatus with seamless link function.
Background technology
High voltage power distribution is not so good as the general of low pressure in life, be mainly used in the input of industrial and mining enterprises, or among electrical power trans mission/distribution system, but how effectively to economize on electricity from source, highly consider, because economize on electricity is mainly used in low-pressure field at present, but during to certain capacity, low-voltage component has been difficult to reach distribution requirement, now then needs to use high pressure economize on electricity.
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 with seamless link function, high voltage input terminal is connected a three-dimensional winding iron core autotransformer, three-dimensional winding iron core autotransformer is star-like connection, output is many tap changer excitation winding, each gear exports to connect and is connected with the corresponding gear of shunting switch, the gear number of shunting switch is identical with the tap number of three-dimensional reel iron core transformer, the gear conversion of shunting switch is what to carry out under the instruction of shunting switch controller, the instruction of shunting switch controller comes from central controller unit, central controller unit drives the gear switch each time of shunting switch controller according to electrical quantity acquisition module and inner instruction setting, electrical appliance is run under minimum suitable voltage.Central controller, simultaneously according to electrical quantity acquisition module and inner instruction setting, when being necessary, completes the conversion and control of economize on electricity to bypass.When appliance starting, use the gear that output voltage is the highest, in normal work, the gear switch each time of shunting switch controller is driven according to electrical quantity acquisition module and inner instruction setting, when meeting electrical equipment and running well, central controller unit, the minimum voltage that is adjusted to by shunting switch that can be orderly exports, electric energy can not only be saved like this, and have protection electrical appliance not easily burn, central controller unit is in running, the magnitude of voltage read raises and maintains a period of time within a period of time, then by sending instructions to shunting switch controller, make it to drive tap to close by current gear to more high tap position (more low-voltage output gear) conversion, until to the most high-grade five grades (minimum output voltage gear), central controller unit is in running, the magnitude of voltage read reduces and maintains a period of time within a period of time, then by sending instructions to shunting switch controller, make it to drive tap to close by current gear to more low-grade location (more high voltage output gear) conversion, until deep low gear one grade (maximum output voltage gear), when central controller unit detects that input voltage can not meet economize on electricity demand, then can Direct driver bypass, disconnect economize on electricity path simultaneously, connect in the course of work in bypass, central controller unit uninterruptedly can judge whether input voltage meets economize on electricity demand, when discovery condition meets, send instruction immediately to shunting switch controller and the work of economize on electricity path contactor, discharge bypass path simultaneously.The high pressure mentioned in the technical program refers to 6KV or 10KV three-phase alternating voltage.
As a kind of optimal way: multiple gear output end voltages of shunting switch are 90% high input voltage terminal voltage ~ 98% high input voltage terminal voltage, when starting the continuous increase of electrical appliance load, the reduction of voltage must be caused, in order to ensure electrical appliance at suitable operating at voltages, central controller unit according to circumstances can send instruction to shunting switch controller, shunting switch is driven first to select suitable gear work, when electrical appliance use interruption needs discontinuity high voltage, central controller unit equally can by inner instruction setting, send instruction to shunting switch controller, shunting switch controller can drive shunting switch to carry out the switching motion of gear equally, guarantee the normal operation meeting electrical appliance, and can effective saves energy.
As a kind of optimal way: three-dimensional reel iron core transformer does not carry out gear switch, but export different voltage by five gears, shunting switch is in respect of gear five, that is shunting switch has five independently position is corresponding with five gears of three-dimensional reel iron core transformer respectively, from the output of shunting switch, export 98% respectively, 96%, 94%, 92%, the high input voltage terminal voltage of 90%, with regard to general electrical appliance, direct-on-line starting is needed when starting, and be to maintain a lower voltage after normally running, just can guarantee the normal operation of electrical appliance, according to the different needs of electrical appliance, central controller unit can send instruction to shunting switch controller, shunting switch is driven to carry out gear conversion, it is all be preset in central controller unit that all gears will change action command, the suitable low-voltage gear of automatic selection can effective saves 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.
In above description of contents, when being all relatively stable for line voltage, by reducing the voltage of output, thus reach the object of saves energy, in fact, the technical program is also applicable to the relatively large situation of voltage ripple of power network (such as: user is powered by 6000 volts of three-phase alternating currents, peak times of power consumption time by day simultaneously, voltage can be corresponding on the low side, and during evening, input terminal voltage is higher).When input terminal voltage is lower, if again by high pressure power saving apparatus, can lower by voltage drop, the minimum essential requirement voltage of electrical appliance can not be met, now central controller unit can work by direct command bypass path, disconnect economize on electricity path, input terminal voltage former state is allowed to export, the path that now economizes on electricity is then standby, after line voltage is increased to certain value, central controller unit sets according to internal processes, send instruction and also perform economize on electricity path start-up operation to shunting switch controller, shunting switch is driven to carry out gear conversion, if line voltage continues to raise within a period of time, then central controller unit, not timing regulation stall, until be adjusted to 90% input voltage, now saves energy also reaches high point.
The invention has the beneficial effects as follows: the main body of high pressure economize on electricity is the three-dimensional winding iron core autotransformer sealed in, utilize the excitation balance mode of three-dimensional winding iron core and special design feature, 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, select different gears by shunting switch simultaneously, 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.
