Abstract
The utility model relates to an electric power device, particularly the improvement of a transformer. The utility model is characterized in that a coil L1 of an A-phase branch of a first coil is connected in series with a capacitor C0 and a resistor R1; the resistor R1 and the capacitor C0 are connected in parallel; a coil L3 of a C-phase branch is connected in series with an inductance L0 and a resistor R2; the resistor R2 and the inductance L0 are connected in parallel a coil L2 of a B-phase branch is in reverse-phase connection in parallel with the coil L1 of the A-phase branch and the coil L3 of the C-phase branch; both ends M and N are in single-phase input. The b-phase of a secondary coil is the same with a and c; the reverse sealing star points of all end phases are o, a 0, b and c 0 and are three-phase leading out end. The utility model can realize the transformation of three-phase electricity and single-phase electricity.
Description
The utility model relates to power equipment, specifically a kind of improvement of transformer.
At present, people common household electricity and office's electricity consumption be single-phase ac power supply, just must use single-phase motor as working power, the shortcoming of single-phase motor is that starting torque is little, efficient is low, and using three-phase alternating-current motor as need is to be difficult to accomplish, and can only be to set up a three-phase wire in addition, the occasion institute requirement big to meet starting torque, that efficient is high; Its shortcoming is that three-phase electricity needs stringing again, and infusion of financial resources is big, expense height, indoor complex circuit.
The purpose of this utility model is the shortcoming at above-mentioned existence, and a kind of multiple electricity consumption occasion requirement that adapts to is provided, transformer that can single three phase supply.
Technical essential of the present utility model is: it realizes single three phase supply by the change to primary and secondary coil connected mode, it is characterized in that the A phase branch road coil L of primary coil
1With capacitor C in parallel
0And resistance R
1Serial connection, the coil L of C phase branch road
3With inductance L in parallel
0And resistance R
2Serial connection, the coil L of B phase branch road
2With the A coil L of branch road mutually
1With the C coil L of branch road mutually
3Parallel connected in reverse phase, the single-phase input of two ends M, N; The opposite envelope of identical each end with a, c of secondary coil b asterism is 0, a
0, b
0, c
0Be the three-phase exit.
Appearance of the present utility model can realize that the conversion of single-phase electricity and three-phase electricity is used, and when using three phase electric machine, need not prepare three-phase power line, and is as the driving of the motor of civilian well, electric water pump water lift, wood craft machines, all comparatively convenient.It is simple in structure, and is easy to use, easy to utilize.
Description of drawings:
Fig. 1 is a wiring schematic diagram of the present utility model.
Fig. 2 is the vector relations schematic diagram of Fig. 1.
From accompanying drawing as seen, primary coil A addition capacitor C of the present utility model
0But 60 ° of phase shifts, C addition inductance L
0Phase shift-60 °, 180 ° of the opposite phase phase shifts of B, secondary coil L
1', L
2', L
3' be connected into Y shape, U
a, U
b, U
cBe mutually 120 °, three phase mains.
This single three phase mains conversion can be passed, and when single-phase bigger load can cause three-phase imbalance, such as exchanging the single-phase electricity welding machine, utilizes the utility model to power load balancing simultaneously with regard to available three phase mains synthetic single phase alternating current power supply A, B, C.
