Description

(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ПОТЕНЦИАЛА ПОДЗЕМНОГО МЕТАЛЛИЧЕСКОГО СООРУЖЕНИЯ, ПОЛЯРИЗУЕМОГО ПУЛЬСИРУЮЩИМ ТОКОМ(54) DEVICE FOR MEASUREMENT OF THE POTENTIAL OF UNDERGROUND METAL CONSTRUCTION, POLARIZED BY A PULSE CURRENT

Claims (2)

Формула изобретения Claim Устройство для измерения потенциала подземного металлического сооружения , поляризуемого пульсирующим током, содержащее измерительный прибор, включенный между контролируемым сооружением и электродом сравнения, расположенным над сооружением, прерыватель тока с формирователем командных сигналов и ключом, установленным в цепи питающего тока, отличающееся тем, что, с целью повышения точности и обеспечения воспроизводимости результата измерения, в прерыватель тока введены блок выделения моментов максимума пульсирующего тока, блок совпадения и триггер, причем выходы блока выделения моментов максимума пульсирующего тока и формирователя командных сигналов подключены ко входу блока совпадения, выход которого через триггер соединен с управляющим входом ключа.A device for measuring the potential of an underground metal structure polarized by a pulsating current, comprising a measuring device connected between the structure being monitored and a reference electrode located above the structure, a current chopper with a command signal shaper and a key installed in the supply current circuit, characterized in that, for the purpose of increasing accuracy and ensuring reproducibility of the measurement result, a block for extracting the moments of the maximum ripple current is introduced into the current chopper, the block coincides Denia and a trigger unit which outputs selection moments maximum pulsating current generator and control signals are connected to the input matching unit, the output of which through the flip-flop is connected to the control input of the key. 35 .
