Description
Technical field
The utility model relates to the frequency converter field in the electric power transfer, particularly relates to a kind of control power supply that is used for high voltage converter device that supplies power with double circuit.
Background technology
High voltage converter is widely used in playing the part of important role aborning on the high-power important motors such as blower fan, water pump, elevator as the high-voltage motor speed regulating device.Therefore the reliability of high voltage converter is had higher requirement, particularly after high pressure is carried electricity, hope that high-voltage frequency converter controller can continue maintenance work, various protections and warning function should continue to remain valid, and avoid occurring major accident.In high voltage converter, the power supply reliability of control power supply is most important for the steady operation of whole frequency converter.Only have the mode reliability of one tunnel power supply low, in case break down, will cause controlling power supply can't supply power, and makes the operation paralysis of whole frequency converter.
For eliminating above-mentioned influence, have now and mainly contain two kinds of solutions:
A kind of way is that 220V is exchanged behind uninterrupted power supply (ups) Unity as the power supply power supply, but because bearing power is big, the weak point of holding time of UPS battery, can only solves in short-term and disturb, to the 220V of long period exchange power down then incapability be example.
Another kind is or adopts the multichannel externally fed, one road 220V for example, and one road 380V, but because these all adopt externally fed, still there is control dead electricity risk in outside different range fault.
The utility model content
The utility model is to the problem of above-mentioned existence, and a kind of control power supply that is used for high voltage converter that makes the reliability that the high voltage converter reliability of operation improves, increases to greatest extent frequency converter greatly device that supplies power with double circuit is provided.
The control power supply that is used for high voltage converter of the utility model device that supplies power with double circuit; Comprise master control power supply, the output of transformer secondary, automatic switching control equipment; Said master control power supply all is connected with the input of automatic switching control equipment with the inner transformer secondary output of frequency converter; When the master control power supply breaks down, automatically switch to the output of transformer secondary by automatic switching control equipment;
The output of said automatic switching control equipment connects uninterrupted power supply UPS; When master control power supply dead electricity and automatic switching control equipment fault; Provide control electric by UPS, UPS connects friendship/straight current transformer, exports three road direct voltages afterwards through filtering, rectification and the unsteady flow of friendship/straight current transformer.
The control power supply that is used for high voltage converter of the utility model device that supplies power with double circuit, said automatic switching control equipment is made up of 2 A.C. contactors and 1 relay.
Compared with prior art the beneficial effect of the utility model is: 1, the control power supply of the utility model adopts frequency converter outside, inner multiple-way supply; When abnormal electrical power supply appears in the outside; Can switch to in-line power; Guarantee to control the power supply operate as normal, the high voltage converter reliability of operation is improved greatly.
2, the utility model adopts ups power; In switching device shifter or outside, the internal control power supply simultaneously dead electricity the time, still can guarantee the normal operation of frequency converter, in the UPS power supply; Can change switching device shifter quickly, increase the reliability of frequency converter to greatest extent.
Description of drawings
Fig. 1 is control power supply that the utility model the is used for high voltage converter manipulated or operated apparatus that supplies power with double circuit.
