Description
Technical field
The utility model belongs to power technique fields, more specifically to the improvement with multi-functional EPS power supply of power-equipment and production line.
Background technology
Existing many production lines, power-equipment have been used frequency converter widely, have brought many benefits.But a disadvantage has also appearred; promptly significantly cave in or during the outage of Millisecond, all can make frequency converter protect shutdown immediately, thereby cause production line or power-equipment out of service when line voltage moment; cause a large amount of waste products or serious accident, cause generation to be lost than large economy.
The way of Xie Jueing is before: one, solve with large-scale uninterrupted power supply (ups) Unity.The costly investment of this way is big, and because the efficient of UPS only about 90%, has been wasted a large amount of electric energy in vain.The workload of UPS operation maintenance is very big in addition.Therefore, this is a very uneconomical and worthless way.Its two, solve with the large-scale high-precision pressurizer.Though this way is economical, can solve the problem that transient voltage significantly caves in or raises, can not solve frequent Millisecond outage problem.Production line or power-equipment can shut down because of the Millisecond outage equally, stall, have serious consequences.Therefore, this way is also undesirable.
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of above-mentioned disadvantage that solves is provided, not only exportable interchange, also exportable direct current; Can voltage stabilizing, frequency stabilization, online zero is switching uninterrupted for exchanging or direct current, but the emergency service of part backup type again has the function more complete than Large UPS; And have only the price of high accuracy pressurizer, reliable, simple in structure, economical and practical power-equipment and production line are with multi-functional EPS power supply.
Summary of the invention
In order to achieve the above object, the utility model by shell, be installed in the circuit in the shell and the panel that is installed on the shell is constituted.Circuit comprises the threephase switch that is connected on the 380V AC network, the interlocking change over switch that is connected with threephase switch, the interchange that is connected with the interlocking change over switch output of meeting an urgent need, the rectifier that is connected with threephase switch, the inverter that is connected with rectifier, the elementary winding of the isolating transformer that is connected with inverter, the online uninterrupted output of the interchange that is connected with the isolating transformer secondary winding, the charger that is connected with threephase switch, the battery pack that is connected with charger, the DC-DC converter that is connected with charger, be connected the diode between charger and the rectifier output end, the diode cathode that is connected with DC-DC converter is connected the frequency converter on the diode cathode and is connected second threephase switch on the 380V AC network.The output of second threephase switch is connected with above-mentioned frequency converter.Another road of interlocking change over switch is connected the isolating transformer secondary winding and exchanges between the emergent output.
The output of DC-DC converter also is connected with the positive pole of the diode on another road, and the negative pole of this diode is connecting another road frequency converter.Connecting the 3rd threephase switch between another road frequency converter and the 380V AC network.
When line voltage just often, each electrical equipment of production line or power-equipment all normally the operation.When line voltage moment significantly caves in or when rising or Millisecond outage, direct current output online immediately zero of the present utility model is switched and is given the frequency converter supplementary power, keeps the frequency converter operate as normal.The online uninterrupted output of interchange of the present utility model simultaneously still keeps frequency-and voltage-stabilizing to export to the important system power supply of non-frequency device electricity consumption.Non-important system can not cause because of the fluctuation of voltage is out of service than large economy loss, thereby the output of the utility model emergency service still be mains supply, keeps moving.
When the electrical network instant cut-off, or during short supply interruption, frequency converter in production line or the power-equipment can rely on the direct current output in the utility model to keep the normal operation of certain hour, and the non-frequency device electricity consumption important system in production line or the power-equipment can lean on the uninterrupted output of the interchange of this power supply to keep the normal operation of certain hour.At this moment, immediately the emergency service loop to be connected the output AC electric energy be that the non-important system of non-frequency device is carried out emergency service (switching time was less than 0.1 second) to the interlocking change over switch.Realized that thus outage continues operation.The time of outage back operation is on customer requirements and what of setting battery are decided.Because same DC source (battery pack) is all used in each the road output of this power supply, when battery discharge finishes, above-mentioned production line or power-equipment will be shut down thereupon.When mains supply recovered, frequency converter changed mains supply immediately into, and battery will be charged by charger, and the emergency service of this power supply will change mains supply into by the interlocking change over switch.Therefore, it to be particularly useful for being dragged by frequency converter be the main various power-equipments that constitute.The important system that can be the non-frequency device electricity consumption in power-equipment or the production line provides the online zero switching uninterrupted power supply of interchange of a frequency stabilization, voltage stabilizing, provides the reserve emergency service to non-important system; The frequency converter that can be in power-equipment or the production line provides a stable DC power-supply system, ensures frequency converter interrupt run not when line voltage fluctuation or short supply interruption.It exchanges output a high-quality power supply of high accuracy is provided, and can ensure that important system avoids influences such as voltage ripple of power network, impact, clutter, in order to avoid equipment is out of control or components from being damaged, guarantees the reliability of electricity consumption.Exchange output an emergency power supply system that switches at a high speed also is provided, can ensure the emergency service of non-important system, to guarantee the normal operation of equipment.Direct current output provides a DC power-supply system, for the normal operation of frequency converter in the equipment provides power supply to ensure.It is fit to big and frequent production line or the power-equipment of load change; Also be fit to motor, perception, the various loads of capacitive.
It exchanges output and adopts the isolating transformer design, makes system's operation more safe and reliable.
Battery pack monitoring panel also is installed on the shell.Be installed with on the battery pack monitoring panel and can show the numbering of damaging battery and the display of voltage.Battery pack monitoring panel can be monitored the state of every battery of each battery pack, in case certain piece battery damages, panel will show the numbering and the voltage of this battery, and battery can onlinely be changed.
Task of the present utility model comes to this and finishes.
The utility model provides a kind of not only exportable interchange, also exportable direct current; Can voltage stabilizing, frequency stabilization, online zero is switching uninterrupted for exchanging or direct current, but the emergency service of part backup type again has the function more complete than Large UPS; And have only the price of high accuracy pressurizer, reliable, simple in structure, economical and practical power-equipment and production line are with multi-functional EPS power supply.Its great advantage is significantly to cave in or Millisecond outage or adopt direct current supply to compensate to frequency converter during outage when longer or power at line voltage, keeps stable operation.It can be widely used in the power supply of various power-equipments and production line.
