DEVICE FOR MONITORING OF CONVERTER HIGH-VOLTAGE VALVE CONDITION Russian patent published in 2010 - IPC H02H7/10 

FIELD: electricity.

SUBSTANCE: in device for converter high-voltage valve condition monitoring, comprising units of high-voltage valve power keys condition monitoring by number of serially connected power keys, each unit of high-voltage valve keys condition monitoring comprises rectifier, resistor, also stabilitron and capacitor are included, connected in parallel to outputs of rectifier, unit of synchronisation, unit of delay and generation of pulses, with according time delays of pulses and key introduced between the second output of rectifier and the second input of optical transmitter arranged in the form of light diode, besides, control input of key is connected via unit of delay and generation of pulses with output of synchronisation unit connected by one input to input of rectifier, and by the second input - to the second output of rectifier, and optical receiver is arranged, for instance in the form of photodiode and is intended for all units of keys condition monitoring.

EFFECT: reduction of consumed power and cost of device, simplification of design, expansion of functional capabilities.
