DEVICE PREVENTING FORMATION OF X-RADIATION AND VOLTAGE EXCESS IN CATHODE-RAY TUBE OF COLOR DISPLAY |
摘要 |
FIELD: electronics. SUBSTANCE: increased voltage or voltage of heater caused by anomalous operation of monitor and fed to cathode-ray tube of color display or increased voltage fed from power supply source to peripheral circuit is detected and disconnected to prevent formation of X-radiation and increased voltage. Anomalous voltage across output voltage leads is used for direct control over part of power supply source and output part of horizontal deviation. EFFECT: ensured stability of power supply source, reduced consumption of power and early prevention of peripheral circuits against burning out due to abnormally high voltage. 7 cl, 4 dwg
