Device for monitoring thyristors of high-voltage valve

Thyristor voltage detectors (1) are coupled via light guides (2) through a selector (7) to a buffer storage unit (13), OR gate assembly (14), an adder (16), a memory unit (19), and a comparison unit (25) which are coupled also to a control unit (9). The comparison unit (25) is connected to both the...

Beschreibung
Zusammenfassung:	Thyristor voltage detectors (1) are coupled via light guides (2) through a selector (7) to a buffer storage unit (13), OR gate assembly (14), an adder (16), a memory unit (19), and a comparison unit (25) which are coupled also to a control unit (9). The comparison unit (25) is connected to both the adder (16), and the memory (19), and its output controls an indicator (30) signalling the quantity of disabled thyristors, and a unit (32) protecting the high-voltage rectifier against breakdown. The selector (7) is also connected to an indicator (11) signaling the numbers of the disabled thyristors.
