るブラウン管内放電保護回路。In the cathode ray tube discharge protection circuit, the spark gap has one end connected to an electrode pin led out from inside the cathode ray tube and the other end connected to an exterior carbon coating of the cathode ray tube via a ground lead wire. In a cathode ray tube, a lead wire having a capacitor connected in series is connected in parallel with the ground lead wire in order to make the impedance between the other end and the outer carbon coating low with respect to spark current. Discharge protection circuit.
