Пристрій для контролю ресурсу повітряних високовольтних вимикачів

Abstract

The device for tracking of air high-voltage circuit-breaker resource comprises a current sensor, the first, second and third comparator inputs are connected among them. The pressure sensor outputs are connected to the fourth and fifth comparator inputs. The first pulse oscillator is connected with the third AND element input, the second input being connected to a switching output and the third input is connected with a pulse shaper input. In the device there is a AC / DC voltage converter, a motion start sensor, a voltage sensor, the sixth and seventh comparators, the second and third OR elements, the fourth, fifth, sixth and eighth AND element, the second differentiating element, a flip-flop, the second pulse oscillator, a signal delay unit, the fifth pulse counter, on/off time initialization unit, the third digital comparator, the and second indicators.
