Abstract
The utility model discloses a dephasing filter transformer which includes a transformer mounting rack (1), an iron core (2) and a winding (3), wherein the transformer mounting seat (1) is provided with the iron core (2), and the winding (3) encircles the peripheral side of the iron core (2). The winding is characterized in that the winding (3) is winded by board-type materials, and the winding (3) is made of annular copper bars. The winding winded by annular copper bars is arranged outside of the iron core (2). The purposes of purifying power source and filtering the surges, transient currents and ultraharmonics in circuit are achieved when the made-up dephasing filter transformer serializes in a main return circuit and supplies power, thus the three-phase imbalance is relieved effectively and the power factor is improved. The load of effects caused by vortexes and ultraharmonic component is further reduced greatly when the dephasing filter transformer is used in an inductive load. The dephasing filter transformer further has the advantages of being simple in structure, small in space, convenient to use and economic and effective, and the dephasing filter transformer is suitable to be popularized.
Description
Technical field
The utility model relates to the transformer technology field, specifically a kind of phase-shift filtering transformer that improves three-phase imbalance, improves power factor (PF) and utilization rate of electrical.
Background technology
Existing transformer often can produce the factor that surge, wink stream, high order harmonic component etc. affect the systematic electricity quality in the circuit in power supply process; When transformer used in inductive load, inductive load often can be subject to the impact of eddy current, higher harmonic components, thereby caused a large amount of electric energy losses.
Summary of the invention
The purpose of this utility model is the defective for prior art, and a kind of phase-shift filtering transformer that improves three-phase imbalance, improves power factor (PF) and utilization rate of electrical is provided.
The purpose of this utility model solves by the following technical programs:
A kind of phase-shift filtering transformer comprises transformer installing rack, iron core and winding, and the transformer installing rack is provided with iron core, and all side rings of iron core are wound with winding, it is characterized in that described winding is formed by the board-like material coiling.
Described winding adopts copper bar to make.
The copper bar that described winding adopts is annular.
The utility model has the following advantages compared to existing technology:
The winding that the utility model turns to by the arranged outside annular copper bar at iron core, when the phase-shift filtering transformer of making seals in main circuit power supply, can reach the purpose of surge in power conditioner, the filtering circuit, wink stream, high order harmonic component, effectively improve three-phase imbalance, improve power factor (PF); When using in inductive load simultaneously, but the decrease load improves the power quality of system because of the impact of eddy current, higher harmonic components, and has characteristics simple in structure, that take up an area little, easy to use and economical and efficient, suitable promoting the use of.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Wherein: 1-transformer installing rack; 2-iron core; 3-winding.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1: a kind of phase-shift filtering transformer, comprise transformer installing rack 1, iron core 2 and winding 3, transformer installing rack 1 is provided with iron core 2, all side rings of iron core 2 are wound with winding 3, this winding 3 is formed by the board-like material coiling, and further, winding 3 adopts the copper bar of annular to make.The winding 3 that the utility model turns to by the arranged outside annular copper bar at iron core 2, when the phase-shift filtering transformer of making seals in main circuit power supply, can reach the purpose of surge in power conditioner, the filtering circuit, wink stream, high order harmonic component, effectively improve three-phase imbalance, improve power factor (PF); When using in inductive load simultaneously, but the decrease load improves the power quality of system because of the impact of eddy current, higher harmonic components, and has characteristics simple in structure, that take up an area little, easy to use and economical and efficient, suitable promoting the use of.
Above embodiment only is explanation technological thought of the present utility model, can not limit protection range of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on the technical scheme basis all falls within the utility model protection range; The technology that the utility model does not relate to all can be realized by prior art.
