Abstract
The utility model discloses a high-voltage frequency converter control power supply circuit uninterruptible power supplying device, which is provided with two groups of alternating-current input terminals, wherein one group is a single-phase 220V alternating-current input terminal which is connected with a single-phase rectification circuit, an output of the single-phase rectification circuit is connected with an input of a direct current /direct current converter after capacitor filtering, another group is characterized in that a group of 220V alternating-current input which is led in via a DCS uninterruptible power supply UPS is connected with another single group of single-phase rectification circuits, and the output of the single-phase rectification circuits is connected into the input of the direct current /direct current converter after capacitor filtering. The uninterruptible power supplying device adopts the UPS backup power supply and the 220V control power supply to form a circuit power supply, when the 220V control circuit is in abnormal power supply, the uninterruptible power supplying device sufficiently utilizes the existing UPS backup power supply so as to ensure normal operation of the high-voltage frequency converter control power supply, and the uninterruptible power supplying device has the advantages of low cost and reliable practicable effect.
Description
Technical field
The utility model relates to high voltage converter control electric power loop uninterrupted power supply device, has solved high voltage converter control loop dead electricity possibility, and is shared with existing DCS uninterrupted power supply, improved the high voltage converter functional reliability.
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, wish 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.
The above-mentioned power supply source of existing high voltage converter control circuit only has one tunnel power supply, and reliability is low, in case have the technical scheme fault, will cause controlling power supply can't power, and makes the operation paralysis of whole frequency converter.
Summary of the invention
Technical problem to be solved in the utility model is the above-mentioned deficiency at prior art, provides a kind of simple in structure, and outstanding effect high voltage converter control electric power loop uninterrupted power supply device is to improve the operational reliability of equipment.
It is two groups that high voltage converter control power supply uninterrupted power supply device exchanges input terminal: wherein one group is that single-phase 220V exchanges input terminal, connects a single phase rectifier circuit, and the output of single phase rectifier circuit connects behind capacitor filtering directly/the directly input of current transformer; Wherein another group is to introduce one group of 220V through DCS uninterrupted power supply UPS to exchange input, connects independent one group of single phase rectifier circuit in addition, and the output of single phase rectifier circuit inserts behind capacitor filtering directly/the directly input of current transformer.
High voltage converter control power supply uninterrupted power supply device, two groups of single phase alternating current (A.C.) inputs insert together always behind current rectifying and wave filtering circuit/straight current transformer.Form high voltage converter control power supply uninterrupted power supply device, simultaneously mutual electrical isolation between the three.Briefly, promptly described straight/straight current transformer provides multiple different output voltage V 1, V2, V3; Wherein master control 220V power supply exchanges input connection No. one rectification circuit, and inserts straight/straight current transformer through electric capacity.
The utility model adopts UPS back-up source and 220V control power supply to form and loop power supply.When wherein abnormal electrical power supply appears in the 220V control loop, guarantee high voltage converter control power supply operate as normal, the high voltage converter reliability of operation is improved greatly.High voltage converter control power supply uninterrupted device has made full use of existing UPS back-up source, have with low cost, the reliable characteristics of practical function.

Embodiment
Below in conjunction with description of drawings the utility model is further elaborated.
Fig. 1 is a preferred version of the present utility model, its shown high voltage converter control power supply by directly/straight current transformer 3 provides.Directly/directly current transformer 3 provides multiple different output voltage V 1, V2, V3, connects various controllers respectively as controller power source.Wherein master control 220V power supply exchanges input connection No. one rectification circuit 1, and rectification circuit 1 becomes direct current with the AC rectification of input, and after electric capacity 2 filtering filtering alternating components, inserts straight/straight current transformer 3.When the direct voltage that produces when external master control 220V power supply is low, start working by another loop that the UPS of DCS system back-up source 4 provides, equally through another independent single phase rectifier circuit 1 output after electric capacity 2 filtering, insert the input of straight/straight current transformer 3.Formation is uninterruptedly controlled electric power loop by the high voltage converter of UPS back-up source 4 power supplies.Before inserting uninterrupted control supply unit, both exchange mutual electrical isolation between the input for it.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
