Abstract
The utility model discloses a kind of dynamic capacity regulating reactor for filtering compensation device, comprises main coil, secondary coil, switching device, optical fiber and controller.Described secondary coil is connected with switching device, and switching device is by controller described in Fiber connection.The target capacity value that described controller regulates needed for reactor, export corresponding switching signal to switching device, the filtering compensation device that switching device produces under described switching signal controls needs the electric current exported, and this electric current is exported to secondary coil, thus realize the adjustment of reactor capacity.The target capacity value regulated needed for reactor and filtering compensation device need the electric current that exports corresponding, and the electric current that switching device produces can export corresponding switching signal by controller and realizes electrodeless adjustment, therefore the utility model achieves the dynamic electrodeless capacity transfer of reactor, the utility model is not by tap number quantitative limitation simultaneously, degree of regulation is high, can reach the filter effect that filtering compensation device is good.
Description
Technical field
The utility model relates to reactor capacity transfer technical field, particularly relates to a kind of dynamic capacity regulating reactor for filtering compensation device.
Background technology
In filtering compensation device, because capacitor exists foozle and alignment error, in order to reach good filter effect, usually require that the filter reactor capacity of series connection with it is adjustable.Tradition regulative mode makees a secondary coil outward again at the main coil of reactor, and on secondary coil, reserved some taps, reach by the link position changing main coil and secondary coil the object regulating reactor capacity.But this regulative mode is by tap number quantitative limitation, and degree of regulation is low, can not realize step-less adjustment.
Utility model content
The purpose of this utility model is, by a kind of dynamic capacity regulating reactor for filtering compensation device, to solve the problem that above background technology part is mentioned.
For reaching this object, the utility model by the following technical solutions:
For a dynamic capacity regulating reactor for filtering compensation device, it comprises main coil, secondary coil, switching device, optical fiber and controller; Described secondary coil and switching device are electrically connected, and described switching device is by controller described in Fiber connection; The target capacity value that described controller regulates needed for reactor, exports corresponding switching signal to switching device, and the filtering compensation device that switching device produces under described switching signal controls needs the electric current exported, and this electric current is exported to secondary coil.
Especially, described switching device selects high-power inverter.
The target capacity value regulated needed for reactor for the dynamic capacity regulating reactor middle controller of filtering compensation device that the utility model proposes, export corresponding switching signal to switching device, the filtering compensation device that switching device produces under described switching signal controls needs the electric current exported, and this electric current is exported to secondary coil, thus realize the adjustment of reactor capacity; The target capacity value regulated needed for reactor and filtering compensation device need the electric current that exports corresponding, and the electric current that switching device produces can export corresponding switching signal by controller and realizes electrodeless adjustment, therefore the utility model achieves the dynamic electrodeless capacity transfer of reactor, the utility model is not by tap number quantitative limitation simultaneously, degree of regulation is high, can reach the filter effect that filtering compensation device is good.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.Be understandable that, specific embodiment described herein only for explaining the utility model, but not to restriction of the present utility model.It also should be noted that, for convenience of description, the part relevant to the utility model is illustrate only but not full content in accompanying drawing, unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of term used herein just in order to describe specific embodiment, is not intended to be restriction the utility model.
Please refer to shown in Fig. 1, the dynamic capacity regulating reactor structure chart for filtering compensation device that Fig. 1 provides for the utility model embodiment.
Main coil 101, secondary coil 102, switching device 103, optical fiber 104 and controller 105 is specifically comprised for the dynamic capacity regulating reactor of filtering compensation device in the present embodiment.Described secondary coil 102, round described main coil 101, is electrically connected with switching device 103; Described switching device 103 connects described controller 105 by optical fiber 104.
During work, first, described controller 105, by harmonic current, the voltage in detection system, calculates the electric current that filtering compensation device needs to export, thus obtains the required target capacity value regulated of reactor; Secondly, the target capacity value that controller 105 regulates needed for described reactor calculates the switching signal needing to export to switching device 103, the filtering compensation device that switching device 103 produces under described switching signal controls needs the electric current exported, and this electric current is exported to secondary coil 102, thus realize the adjustment of reactor capacity.The target capacity value regulated needed for reactor and filtering compensation device need the electric current that exports corresponding, and the electric current that switching device 103 produces can export corresponding switching signal by controller 105 and realizes electrodeless adjustment, therefore the utility model achieves the dynamic electrodeless capacity transfer of reactor, the utility model is not by tap number quantitative limitation simultaneously, degree of regulation is high, can reach the filter effect that filtering compensation device is good.It should be noted that, the kind of described switching device 103 is a lot, and repeat no more, switching device 103 described in the present embodiment selects high-power inverter.High-power inverter herein refers to the inverter of power at more than 50KW.
Note, above are only preferred embodiment of the present utility model and institute's application technology principle.Skilled person in the art will appreciate that the utility model is not limited to specific embodiment described here, various obvious change can be carried out for a person skilled in the art, readjust and substitute and protection range of the present utility model can not be departed from.Therefore, although be described in further detail the utility model by above embodiment, but the utility model is not limited only to above embodiment, when not departing from the utility model design, can also comprise other Equivalent embodiments more, and scope of the present utility model is determined by appended right.
