Abstract
The utility model relates to a kind of power transformer no load energy-saving device.Comprise reactor, by-pass switch and controller, by-pass switch is in parallel with reactor, and by-pass switch can by reactor short circuit, and by-pass switch is electrically connected with controller, and controller automatically can detect having of transformer and carry and idling, and can control by-pass switch.Its structure is simple, greatly can reduce transformer noload losses.
Description
Technical field
The utility model belongs to power transformer, particularly a kind of power transformer no load energy-saving device.
Background technology
Consider from technical standpoint with regard to current, the no-load loss of power transformer is inextirpable, also allows there is certain loss when power transformer no-load running with national standard and IEC standard.But this loss is too large for country's loss, both transformer noload losses accounted for about 20% of whole capacity.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of power transformer no load energy-saving device, and its structure is simple, greatly can reduce the no-load loss of transformer.
The technical scheme in the invention for solving the technical problem is: comprise reactor, by-pass switch and controller, by-pass switch is in parallel with reactor, by-pass switch can by reactor short circuit, by-pass switch is electrically connected with controller, controller automatically can detect having of transformer and carry and idling, and can control by-pass switch.
The utility model has following advantages: 1), structure is simple, and cost is low; 2), can supporting current any power transformer; 3), no-load transformer electric current and loss can effectively be reduced; 4), coordinate transformer master to enter switching manipulation and effectively can reduce inrush current of transformer and disjunction transformer cut-off overvoltage.Greatly can reduce transformer noload losses.
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 reactor 1, by-pass switch 2 and controller (not shown in FIG.), by-pass switch 2 is in parallel with reactor 1, by-pass switch 2 can by reactor 1 short circuit, by-pass switch 2 is electrically connected with controller, controller automatically can detect having of transformer and carry and idling, and can control by-pass switch 2.
Described reactor 1 is iron-core reactor.
Described by-pass switch 2 is permanent magnetic vacuum switch.
During use, the primary windings connected in series of the utility model and transformer.Automatically access during no-load transformer, have when carrying and automatically excise.
The main switch folding order of the utility model and transformer: close no-load transformer, first drop into the utility model, then close main switch, excise high reactance more afterwards, can reduce to shove; During disjunction transformer, first excise the utility model, then divide main switch, cut-off overvoltage when can prevent perceptual small area analysis from excising.
