The insulating transformer outputs the uninterrupted alternating current and the hold-off diode outputs the uninterrupted direct current. The main switch and the output end of the insulating transformer are also connected with an interlocking alternation switch whose emergency output is connected with the energy consumption of unimportant facilities. The uninterrupted power supply has the characteristics of complete function, low price, reliable operation and simple structure, has the compensation effects for the instant voltage substantial suspension and the millisecond level power off with great safety redundant volume, is particularly applicable for the environment with poor electricity network and can be widely applied for the power supply for various assembly line and power equipment with big load fluctuation and frequent change.
Description
Technical field
The utility model belongs to power technique fields, more particularly relates to the improvement of industrial drives with uninterrupted power supply, is to be used for based on the various production lines of frequency converter driving and the supply unit of power-equipment.
Background technology
The method that is used to solve the frequency converter instant cut-off at present has following two kinds.A kind of is large-scale uninterrupted power supply UPS, and its shortcoming is that expense costliness, efficient are low, and the long-time running power consumption is big, maintenance workload is big.It is uneconomical and worthless scheme.Another kind is to solve with the large-scale high-precision pressurizer, and expense economy can solve transient voltage fluctuation, but can not solve dead electricity or instant cut-off and the problem that causes production line or power-equipment to be shut down.It is a kind of infeasible scheme.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of industrial drives uninterrupted power supply is provided.It has successfully solved the problems referred to above, have the function more complete than Large UPS, and price only is equivalent to high-precision pressurizer.Reliable, simple in structure, economical and practical.The production line or the power-equipment that are fit to the big and frequent variations of the fluctuation of load cave in or the Millisecond outage has compensating action significantly to transient voltage, and safe amount of redundancy is big, is particularly suitable for abominable power grid environment.
In order to achieve the above object, the utility model comprise the master switch that is connected on the electric main, be connected in parallel on charger and rectifier, the inverter that is connected with rectifier, the isolating transformer that is connected with inverter on the master switch, be connected the diode between rectifier and the charger, the batteries that is connected in parallel on the charger output and AC/AC translation circuit, be connected AC/AC translation circuit output high-speed switch, be connected the hold-off diode of high-speed switch output and be connected electric main and high-speed switch between ac detector.The output of isolating transformer is exported uninterrupted alternating current, and the output of hold-off diode is exported uninterrupted direct current, and the input of ac detector is the output AC civil power simultaneously.
The output of master switch and isolating transformer also is being connected the interlocking change over switch, and the emergent output of interlocking change over switch connects the electricity consumption of non-visual plant.
Operation principle of the present utility model is as follows:
When the AC network power supply just often, frequency converter exchanges the access port input AC by it.Straight/DC converter no-load running in the utility model is transformed to the direct current supply voltage that is complementary with the frequency converter DC port with cell voltage, and the input side of delivering to high-speed switch and hold-off diode is standby.This moment, hold-off diode was closed, thereby frequency converter does not obtain energy from the utility model.
When the unexpected dead electricity of AC network (interrupt or super model), after ac detector in the utility model detects the input AC variation, the high-speed switch conducting, direct current is sent into the frequency converter DC port, the voltage that ensures frequency changer direct current bus is stable, thereby has guaranteed the operate as normal and the output of frequency converter.
After the AC network power up was normal, the utility model was deactivated, charger accumulators boost charge simultaneously.
Online uninterrupted duty of the present utility model: when AC power just often alternating current become direct current through rectifier and supply with inverter and become the ac control system power supply that pure sine wave is a frequency converter through isolating transformer; When alternating current lost efficacy, storage battery was through inverter power supply.
Emergency service working method of the present utility model: load at ordinary times and powered through the interlocking change over switch by civil power, when civil power lost efficacy, the interlocking change over switch was cut to inverter power supply, and only be 0.1 second change-over time.
Task of the present utility model comes to this and finishes.
The utility model is the abbreviation of industrial drives uninterrupted power supply, that is DPS.It is to be used for based on the various production lines of frequency converter driving and the power supply ensuring equipment of power-equipment.This installs both output AC electricity, output DC again.And alternating current voltage stabilizing, frequency stabilization; Can realize that online zero switches, uninterrupted Alternating Current Power Supply can provide a jumbo DC uninterrupted power supply again, the emergency service of all right backup type.
Its complete function, cheap.Reliable, simple in structure.Transient voltage is caved in or Millisecond outage has compensating action significantly, and safe amount of redundancy is big, is particularly suitable for abominable power grid environment.It is big and change the power supply of frequent production line or power-equipment to be widely used in the various fluctuations of load.
