Description
(1) technical field:
This utility model belongs to electrical equipment technical field, and especially a kind of single-phase voltage with seamless handover function is mended
Repay device.
(2) background technology:
With the raising of China's modern industrial technology and living standards of the people, power quality problem increasingly highlights, electric energy matter
Amount Treatment process has become as the key solving power quality problem.An outstanding problem of the quality of power supply is voltage dip at present
With short interruptions, corresponding solution mainly has dynamic electric voltage recovery device (dvr), uninterrupted power source (ups), and dynamic electric voltage is temporary
Fall compensator (hereinafter referred to as dysc) etc., wherein, dvr belongs to tandem type device, and when system power supply is interrupted, dynamic electric voltage recovers
Device cannot work；The online loss of online ups is larger and relatively costly, and backup type ups response speed cannot meet sensitivity more slowly
The requirement of load；Dysc is single-phase h bridge topological structure, and its equipment cost is of a relatively high, especially big when the system power supply break period
After 1 second, it is difficult to be widely popularized in industrial quarters.
With the development of industrial automation, controller is as industrial key control unit, the fortune of its safety and stability
Row produces most important to enterprise.Typical controller includes plc and dcs etc., and the control power supply of these controllers commonly enters
For single phase ac 220v civil power, it is output as direct current 24v.The operating mechanism that controller is controlled simultaneously, the such as input such as catalyst
For single phase ac 220v civil power.Thus when civil power occurs voltage dip or short interruptions, controller and associative operation mechanism can
Energy meeting misoperation, thus destroy production procedure running well, is that enterprise brings heavy losses.Simultaneously because controller and related behaviour
Make that mechanism's power is relatively low, traditional voltage compensation schemes based on energy storage are relatively costly and no longer applicable due to it.Therefore develop
A kind of low cost, and it is significant to possess the single-phase voltage compensation device of seamless handover function.
(3) utility model content:
The purpose of this utility model is to propose a kind of single-phase voltage compensation device with seamless handover function, and it is permissible
Overcome the deficiencies in the prior art, be that a kind of structure is simple, the device that function is easily realized；And mains supply occur voltage dip and
During short interruptions, by rapidly switching off bidirectional thyristor by load and the dead electricity isolated from power breaking down, and start single simultaneously

Operation principle of the present utility model: when system power supply ac is normal, system power supply ac passes through bidirectional thyristor to negative
Lotus is powered, and single-phase invertor module is passed through controlled rectification pattern and realized energy stores to the charging of electrochemical capacitor module, works as system
When power supply ac occurs transient voltage fault, single-phase invertor module working condition is by controlled rectification pattern switching to voltage source mould
Formula, realizes effective shutoff of bidirectional thyristor by back-pressure pulse method or load current transfer method, and electrochemical capacitor module is led to
Crossing single-phase invertor module DC side provides energy for the exchange output of single-phase invertor module, and single-phase invertor module is as voltage
To maintain the normal work of load, after system power supply ac recovers normal, single-phase invertor module then exits voltage source work in source
Pattern is simultaneously again started up controlled rectification mode of operation, and bidirectional thyristor is switched on to maintain the normal work of load.
Superiority of the present utility model: 1, do energy-accumulating medium using electrochemical capacitor, and integrated further, effectively reduce
Cost；2nd, during holding state, inverter is in controlled rectification state, and mains supply is powered to load by bidirectional thyristor, so
Not only reduce the loss of device self-operating, be simultaneously achieved On-line self-diagnosis function；3rd, employ and can rapidly switch off IGCT skill
