Transformer noload losses phase compensation device
Art
The utility model belongs to transformer energy saving device, the phase compensation device of particularly a kind of transformer noload losses.
Background technology
It is very large that electricity is lost in transformer noload losses every year.Solar power generation power supply network on daytime in recent years, carry the electric energy (no-load loss) of electrical network evening, a lot of user is also like this.How to reduce empty damage to be really difficult to, because of transformer noload losses mainly core loss, it is relevant to permeability magnetic material and magnetic flux density with eddy current loss by magnetic hysteresis loss, cannot avoid no-load loss from integrated transformers design angle.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of transformer noload losses phase compensation device, and its structure is simple, greatly can reduce transformer noload losses.
The technical scheme in the invention for solving the technical problem is: it comprises transformer electrical parameters detection controller, current transformer, fling-cut switch and pressure regulation capacitor, the output three of transformer electrical parameters detection controller first input end and transformer is connected, transformer electrical parameters detection controller second input is connected with current transformer three-phase electricity, the output of current transformer access transformer, the output of transformer electrical parameters detection controller is electrically connected with fling-cut switch, to control fling-cut switch, pressure regulation capacitor is by the output of fling-cut switch three-phase access transformer.
The utility model has following advantages: 1), for solar power generation step-up transformer carry out unloaded phase compensation, makes original sense phase adjust be capacitive phase angle, greatly can reduce transformer noload losses; 2), automatically adjust phase compensation, automaticity is high; 3), structure is simple, and cost is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the utility model schematic diagram.
Embodiment
As shown in Figure 1, the utility model comprises transformer electrical parameters detection controller 3, current transformer 2, fling-cut switch 4 and hierarchical capacitor 5, the output three of transformer electrical parameters detection controller 3 first input end and transformer 1 is connected, transformer electrical parameters detection controller 3 second input is connected with current transformer 2 three-phase electricity, current transformer 2 accesses the output of transformer 1, the output of transformer electrical parameters detection controller 3 is electrically connected with fling-cut switch 4, to control fling-cut switch 4, pressure regulation capacitor 5 is by the output of fling-cut switch 4 three-phase access transformer 1.
Described transformer electrical parameters detection controller 3 comprises transformer electric parameter detector and controller, and controller controls fling-cut switch 4.
Described controller is single-chip microcomputer or PLC.
During use, transformer electrical parameters detection controller 3 detects the load parameter of transformer 1 automatically, automatically controls excision, the access of pressure regulation capacitor 5 and adjust condenser capacity by fling-cut switch 4.Automatically adjust phase compensation by pressure regulation capacitor 5, make original sense phase adjust be capacitive phase angle, reduce the no-load loss of transformer.
