Accompanying drawing explanation
The line construction functional schematic that Fig. 1 adopts for the utility model.
Embodiment
For understanding the utility model better, set forth below by embodiment.
With reference to figure 1, illustrate a kind of electron tube resisting momentary spike pulse voltage that the utility model provides, comprise order electricity
The ac-dc converter circuit module connected, filtering useless band circuit module, orthogonal stream inverter circuit module, output device, the described electron tube resisting momentary spike pulse voltage also comprises suppressing high-frequency current harmonic wave electrical network to be produced to the electromagnetic filter circuit polluted, in order to improve power factor, reduce harmonic wave, realize the power factor regulating circuit of constant power output, in order to prevent abnormality, the protective circuit of infringement is produced to electron tube, described electromagnetic filter circuit is connected between voltage input end and ac-dc converter circuit module, described power factor regulating circuit is connected between ac-dc converter circuit module and filtering useless band circuit module, described protective circuit is arranged among orthogonal stream inverter circuit module.
