Description

ление резистора 10 равно сопротивлению группы резисторов 8, соединенных через силовые предохранители параллельно.Resistance 10 is equal to the resistance of a group of resistors 8 connected in parallel through the power fuses.

При исправности предохранителей параллельных ветвей катодной группы фазы А в полуобмотках трансформатора 5 протекают токи, равные по величине. При этом на вторичной обмотке трансформатора 5 напр жение равно нулю.When the fuses of the parallel branches of the cathode group of phase A are intact, currents of equal magnitude flow in the semi-windings of the transformer 5. In this case, on the secondary winding of the transformer 5, the voltage is zero.

При сгорании предохранителей в одной или нескольких параллельных ветв х происходит разбаланс токов в первичной обмотке трансформатора 5, так как при сгорании предохранител  нарушаетс  цепь протекани  тока через резистор, включенный последовательно предохранителю и сопротивление группы резисторов увеличиваетс , а на выходе вторичной обмотки трансформатора 5 по вл етс  напр жение , величина которого зависит от количества сгоревших предохранителей.When the fuse blows in one or several parallel branches x, the currents in the primary winding of the transformer 5 are unbalanced, because when the fuse blows, the current flow through the resistor connected in series to the fuse and the resistance of the group of resistors increase, and the output of the secondary winding of the transformer 5 appears voltage, the value of which depends on the number of blown fuses.
