Description
Technical field
This utility model relates to high voltage supply or power transmission and distribution field, the high pressure power saving apparatus of a kind of band seamless link function.
Background technology
High voltage power distribution is not so good as the universal of low pressure in life, it is mainly used in the input of industrial and mining establishment, or among electrical power trans mission/distribution system, but how effectively to economize on electricity from source, highly consider, owing to economize on electricity at present is mainly used in low-pressure field, but during to certain capacity, low-voltage component has been extremely difficult to distribution requirement, the most then need to use high pressure economize on electricity.
Utility model content
Technical problem to be solved in the utility model is: the most effectively save high voltage electric.
This utility model be the technical scheme is that the high pressure power saving apparatus of a kind of band seamless link function, high voltage input terminal one three-dimensional winding iron core autotransformer of series connection, three-dimensional winding iron core autotransformer is star-like connection, outfan is multi-tap pressure regulator Exciting Windings for Transverse Differential Protection, the output of each gear connects the gear corresponding with shunting switch and is connected, 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 to carry out under the instruction of shunting switch controller, the instruction of shunting switch controller comes from central controller unit, central controller unit sets drive the gear switch each time of shunting switch controller according to electrical quantity acquisition module and internal instruction, electrical appliance is made to run under minimum suitable voltage.Central controller sets according to electrical quantity acquisition module and internal instruction simultaneously, it is necessary to time, complete the conversion and control to bypass of economizing on electricity.nullWhen appliance starting，Use the gear that output voltage is the highest，In normal work，Set drive the gear switch each time of shunting switch controller according to electrical quantity acquisition module and internal instruction，In the case of meeting electrical equipment normal operation,Central controller unit,The minimum voltage that is adjusted to by shunting switch that can be orderly exports,So can not only save electric energy，And there is protection electrical appliance and be difficult to burn，Central controller unit is in running,The magnitude of voltage read raises within a period of time and maintains a period of time,Then by issuing a command to shunting switch controller,It is allowed to drive tap to close changed to more high tap position (more low-voltage output gear) by current gear，Until arriving the most high-grade five grades (minimum output voltage gear),Central controller unit is in running,The magnitude of voltage read reduces within a period of time and maintains a period of time,Then by issuing a command to shunting switch controller,It is allowed to drive tap to close changed to more low-grade location (higher voltage output gear) by current gear，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 directly drive bypass,Simultaneously switch off economize on electricity path,In work process is connected in bypass,Central controller unit can uninterruptedly judge whether input voltage meets economize on electricity demand,When discovery condition meets,Issue instructions to shunting switch controller and economize on electricity path catalyst work immediately,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 being continuously increased of electrical appliance load, necessarily cause the reduction of voltage, in order to ensure electrical appliance at suitable operating at voltages, central controller unit can according to circumstances send instructions to shunting switch controller, shunting switch is driven first to select the work of suitable gear, when electrical appliance uses interruption to need discontinuity high voltage, central controller unit can be set by internal instruction equally, send instructions to shunting switch controller, shunting switch controller can drive shunting switch to carry out the switching motion of gear equally, guarantee to meet the normal operation of electrical appliance, and can effective saves energy.
nullAs 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 independent positions corresponding with the five of three-dimensional reel iron core transformer gears respectively，From the outfan of shunting switch，Export 98% respectively、96%、94%、92%、The high input voltage terminal voltage of 90%，For general electrical appliance，Need full-voltage starting on startup，And be to maintain a relatively low voltage after properly functioning，Can ensure that the properly functioning of electrical appliance，Different needs according to electrical appliance，Central controller unit can send instructions to shunting switch controller，Shunting switch is driven to carry out gear conversion，All of gear action command to be changed is all to be preset in central controller unit，Automatically selecting suitable low-voltage gear can effective saves energy.
In the selection of above gear of the present invention, it is that the gear that can meet major part electrical equipment needs at present selects, but the present invention has not limited to above gear and selected.
In above description of contents, when being all that line voltage is stablized relatively, by reducing the voltage of outfan, thus reach the purpose of saves energy, it is true that the technical program applies also for the relatively large situation of voltage ripple of power network (such as: user is powered, peak times of power consumption time by day by 6000 volts of three-phase alternating currents simultaneously, voltage can be the most on the low side, and during evening, input terminal voltage is higher).When input terminal voltage is relatively low, 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, now economize on electricity path is the most standby, after line voltage is increased to certain value, central controller unit sets according to internal processes, send instructions to shunting switch controller and perform path startup operation of economizing on electricity, shunting switch is driven to carry out gear conversion, if line voltage persistently raises within a period of time, then central controller unit, variable interval regulation stall, until regulation is to 90% input voltage, now saves energy also reaches high point.
The beneficial effects of the utility model are: 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 construction features, reach mutual balanced action in magnetic potential in three-phase, make the voltage flowing in electrical equipment be balanced and stablize thus reach the purpose of power saving, select different gears by shunting switch simultaneously, and then export different voltage, electrical equipment is made to 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 sluggishness heavy current impact, minimizing system instantaneous pressure drop, improve system stability, and serve the effect of filtering, improve the power factor of system.
