Zusammenfassung: | The invention discloses a wireless induction type capacitive voltage divider which comprises an induction PCB (printed circuit board), the induction PCB is of a multi-layer PCB structure and sequentially comprises a component base material layer, an induction shielding copper foil layer, an induction copper foil layer and a grounding shielding copper foil layer, and the induction PCB, a matching capacitor, a compensation capacitor, a matching resistor and a sampling interface are arranged on the induction PCB. The matching capacitor and the compensation capacitor form a parallel circuit, one end of the parallel circuit is connected with a high-voltage end through the induction capacitor, the other end of the parallel circuit is grounded, and the sampling interface is connected with the parallel circuit through the induction copper foil layer and the matching resistor. The wireless induction type voltage divider has the advantages that the size is very small, the space of pulse high-voltage equipment is basica |
