Detailed description of the invention
Below in conjunction with detailed description of the invention and accompanying drawing, the present invention is described in further detail.
Seeing Fig. 1, energy-conservation high-frequency and high-voltage power supply, including commutator 1, inverter 2 and transformator 3.
See Fig. 2, commutator 1 includes the first diode D1, second diode D2, first relay K T1, second relay K T2 and electric capacity C, the live wire of extraneous power supply is divided into two-way, one tunnel coil with the first diode D1 and the first relay K T1 successively connects with zero line after being connected again, another road coil with the second diode D2 and the second relay K T2 successively connects with zero line after being connected again, first diode D1 and the second diode D2 is oppositely arranged, the live wire of extraneous power supply and the first relay K T1 switch one end and are connected, the first relay K T1 switch other end is connected with inverter 2, the two ends that second relay K T2 switch ends switchs with the first relay K T1 intersect and are connected, the extraneous zero line of power supply is connected with the zero line of inverter 2.Electric capacity C is arranged between the other end and the zero line of the first relay switch.Electric capacity effect in circuit is filtering.
See Fig. 3, inverter 2 includes that 21 two, motor inputs brush 2a, 2b and two output brush 2c, 2d, a diverter 22 and two output electrodes 23 it are provided with in the rotating shaft of motor 21, 24, diverter 22 is one and is fixed on the collar rotated together with rotating shaft in rotating shaft, diverter 22 is provided with the conducting block 221 being mutually 180 degree a pair, 222, two input brush 2a, 2b contacts with diverter 22, and two input brush 2a, 2b is oppositely arranged, two conducting blocks 221, 222 respectively with two output electrodes 2c, 2d turns on, two output brush 2c, 2d respectively with two output electrodes 23, 24 are conducted.Adopting in this way, inverter does not use any electronic devices and components, and therefore maximum possible avoids energy loss.
