In modern electric power system, the dual power supply pattern that generally employing main power source is powered or stand-by power supply is powered, and from
Dynamic permutator is exactly the switch changing main power source and stand-by power supply, is mainly used in urgent or emergency power supply system, its function
It is that load circuit is automatically switched to another road power supply from a road power supply, to guarantee the uninterrupted power supply to important load, makes
Load i.e. electricity consumption facility is continuously, reliably run.Along with improving constantly that people's power quality requires, they are to automatically turning
The requirement of the performance requirement such as arc extinction ability etc. changing switch is the most harsh.
The most conventional automatic transfer switch controller the most all possesses the voltage status to main power source and stand-by power supply and examines
The function surveyed.When under-voltage, overvoltage or phase shortage having been detected, carry out showing and reporting to the police, and enter by mode set in advance
Row switching, but seldom have controller to have frequency and phase-detection function.And in actual application, supply network has
Time there will be the phenomenon of unbalance in phase and frequency fluctuation, especially electromotor is being used as stand-by power supply, even serving as master
During power supply the most prominent, this can cause gather signal inaccurate.
Utility model content
The purpose of this utility model is to overcome prior art not enough, it is provided that a kind of automatic switch for electric device conversion equipment, its
Also there is while possessing voltage detecting function frequency and phase-detection function.
The technical solution of the utility model is: a kind of automatic switch for electric device conversion equipment, including main power source, stand-by power supply,
Voltage transformation module, A/D modular converter, frequency detection module, phase detecting module, processor, position detecting module,
Driving module and permutator, described main power source and stand-by power supply connect electrical equipment, described master by permutator respectively
Power supply and stand-by power supply connect A/D modular converter, frequency detection module and phase detecting module also by voltage transformation module
Input, the outfan of described A/D modular converter, frequency detection module and phase detecting module is connected with processor,
Described processor is by position detecting module and drives module to be connected with permutator.
Further, described processor is also associated with display and keyboard.
Further, described processor is also associated with alarm module.
Further, described voltage transformation module uses model to be the voltage transformer of ATT7022A.
Further, described processor uses model to be MSP430F1232.
This utility model has the advantage that with good effect: owing to using technique scheme, pass through voltage transformation module
The ac voltage signal of automatic power supply and stand-by power supply is converted to current signal in the future, and described current signal is through A/D modulus of conversion
It is conveyed into processor, it is achieved to magnitude of voltage, frequency and phase after block, frequency detection module and phase detecting module conversion
The detection of position, present design also add frequency, phase-detection on the basis of voltage detecting, gathers signal more accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is elaborated.
Shown in structural representation as of the present utility model in Fig. 1, this utility model provides a kind of automatic switch for electric device conversion equipment,
Including main power source, stand-by power supply, voltage transformation module, A/D modular converter, frequency detection module, phase detecting module,
Processor, position detecting module, driving module and permutator, described main power source and stand-by power supply are opened by conversion respectively
Close and connect electrical equipment, described main power source and stand-by power supply also by voltage transformation module connection A/D modular converter, frequency
Detection module and the input of phase detecting module, described A/D modular converter, frequency detection module and phase detecting module
Outfan be connected with processor, described processor by position detecting module and drive module be connected with permutator.
Described processor is also associated with display and keyboard.Described processor is also associated with alarm module.Described voltage is changed
Module uses model to be the voltage transformer of ATT7022A.Described processor uses model to be MSP430F1232.
The work process of this example: the automatic switch for electric device conversion equipment that this utility model provides, main power source and stand-by power supply
A/D modular converter, frequency detection module and the input of phase detecting module, A/D is connected after voltage transformation module blood pressure lowering
Modular converter sends processor to after being turned by the voltage signal of main power source and stand-by power supply, frequency detection module is used for detecting master
Power supply and the electric voltage frequency of stand-by power supply, described phase detecting module is used for detecting main power source and stand-by power supply whether phase shortage,
Processor detects the two-way three-phase mains voltage of main power source and stand-by power supply automatically, and by the main power source collected and standby electricity
Source voltage, frequency and phase settings compare.When magnitude of voltage is within set point, display display two-way electricity
Source is normal.When measured main power voltage is below or above setting value, processor is measured the most continuously 1 second and is confirmed.
If measured value remains above in the range of acknowledging time or less than setting value, then processor leaves by driving module to control conversion
Pass automatically switches to stand-by power supply and monitors its voltage, and upper limit alarm voltage range is arranged on 380～475V (adjustable), lower limit
Alarm voltage scope is arranged on 285～380V (adjustable).Processor will monitor again double loop power supply voltage automatically.When main power source is extensive
After the most normal, processor automatically switches to main power source by driving module to control permutator and monitors its voltage, and electrical equipment sets
Standby continuation is powered by main power source.Position detecting module for detecting the feedback signal such as splitting or integrating lock and dropout of permutator,
Its input is connected with permutator, and outfan is connected with processor；Drive circuit is that the divide-shut brake of permutator controls
Circuit, it can drive permutator to carry out the switching motions such as separating brake and combined floodgate according to the control signal that processor sends.
When main power source breaks down, such as overvoltage, under-voltage, phase shortage if stand-by power supply also breaks down simultaneously, by setting up
Alarm module can send sound and light alarm, and simultaneous processor will continue the voltage of monitoring double loop power supply, controls conversion to switching nothing
Electric power exports.After arbitrary road power up is normal, output conversion signal accordingly is recovered electric equipment by processor automatically
Power supply.
Above an embodiment of the present utility model has been described in detail, but described content be only of the present utility model relatively
Good embodiment, it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range
Impartial change and improvement etc., within all should still belonging to patent covering scope of the present utility model.
