Abstract

The device for tracking of valve arrester resources comprises current sensor, four flip-flops, an encoder, a NOT element, two AND elements, two pulse generators, an OR element, three pulse counters, a zero setting unit, a signal shaper, a functional generator, a digital comparator. In it there is a time-delay element time, a temperature and voltage sensor the fifth flip-flop, three analog to digital converters, the second and third functional generators, the second and third digital comparators and two display units. Herewith the fourth input of the second AND element is connected with the first digital comparator input and the third input is connected with the second pulse generator. A NOT element output and the second input of the fifth flip-flop are integrated and connected to the second input of the second AND element. The first flip-flop output and the first input of the fifth flip-flop are connected to the first input of the second AND element. The first input of the first analog-to-digital converter is connected to a current sensor and the second input is integrated with the second input of the second analog to digital converter and connected to a time-delay element output, the input being connected to the fourth flip-flop output, the first input being connected to an OR element output and the second input is connected with the first comparator output. A temperature sensor is connected to the firs input of the second analog to digital converter, the output bus being connected to an input digital bus of the second functional generator, the output digital bus being connected to the second digital bus of the second digital comparator. The output digital bus of the first analog-to-digital converter is connected with an input digital bus of the second digital comparator, the output being connected with the first display unit. The first input of the third analog-to-digital converter is connected to a voltage sensor. The fifth flip-flop output is connected to the second input of the third analog-to-digital converter, the output bus being connected with the second input digital bus of the third comparator. The output digital bus of the encoder is connected to input digital bus of the third functional generator, the output digital bus is connected to the first input digital bus of the third digital comparator, the output is connected to the second display unit.
