description | The invention relates to the commutation devices meant for man and animal protection from electrocution, as well as for protection from disconnection of one of the phases of the electrotechnical installations.The device contains a leakage current transducer (1), a preamplifier (2), a comparator (3), a time delay point (4), a thyristor-switch (5) and an interposing relay P2, all being coupled in series, connected to a three-phase network with neutral wire. Between the linear outputs of the device A2, B2, C2 and the neutral wire N there are additionally connected the resistors R1, R2, R3 of equal potential.
Invenţia se referă la dispozitive de comutare destinate pentru protecţia oamenilor şi animalelor de electrocutare, precum şi la protecţia de la deconectarea unei din fazele instalaţiilor electrotehnice.Dispozitivul include un traductor al curentului de scurgere (1), un amplificator preliminar (2), un comparator (3), un ansamblu de reţinere în timp (4), o cheie tiristor (5), un releu intermediar P2 - toate unite consecutiv, conectate la o reţea trifazată cu conductor neutru. Între ieşirile lineare ale dispozitivului A2, B2, C2 şi conductorul neutru N sunt conectate suplimentar rezistoarele R1, R2, R3 cu acelaşi nominal.
Изобретение относится к коммутационным устройствам, предназначенных для защиты людей и животных от поражения электрическим током, а также для защиты от отключения одной из фаз электротехнических установок.Устройство содержит последовательно соединенные датчик тока утечки (1), предварительный усилитель (2), компаратор (3), узел временной задержки (4), тиристорный ключ (5), промежуточное реле P2, подключенные к трехфазной сети с нулевым проводом. Между линейными выходами устройства A2, B2, C2 и нулевым проводом N дополнительно подключены сопротивления R1, R2, R3 одинакового потенциала. |
