Abstract
УСТРОЙСТВО ДЛЯ ЗАИЩТНОГО ОТКЛЮЧЕНИЯ С ЗАВИСИМЫМ ВРЕМЕНЕМ СРАБАТЬВАНИЯ, содержащее датчик тока утечки, к выходу которого подключен выпр митель, выход которого через компаратор подсоединен к интегрирующему входу интегратора, а выход интегратора подключен к первому пороговому блоку, при этом к обнул ющему входу интегратора подключен выходом блок сброса интегратора на ноль, вход которого св зан с выходом выпр мител , с тличающее с тем, что, с целью расширени диапазона уставок срабатывани и токовременных характеристик и обеспечени возможности их независимой регулировки, в него введен второй S . пороговый блок, вход которого подV ) ключен к выходу выпр мител , а выход - к входу блока сброса интегратора на ноль.A DEVICE FOR PROTECTIVE DISCONNECTION WITH A DEPENDENT CLOSING TIME, containing a leakage current sensor, to the output of which a rectifier is connected, the output of which is connected to the integrator's integrator input through a comparator, and the integrator output is connected to the first threshold unit of the integrator, and to the integrator's integrator input, while the integrator's output connector is connected to the integrator's integrator input, the integrator's output is connected to the first threshold unit of the integrator, and the integrator's output is connected to the first threshold unit of the integrator. resetting the integrator to zero, the input of which is connected to the output of the rectifier, in contrast to the fact that, in order to expand the range of operation settings and current-time characteristics and ensure tim possibility of their independent adjustment, it entered the second S. the threshold unit, whose input is V is connected to the output of the rectifier, and the output is to the input of the integrator reset unit to zero.
