DEVICE FOR PROTECTIVE DISCONNECTION IN AC CIRCUIT WITH GROUNDED NEUTRAL |
摘要 |
FIELD: electrical engineering, in particular, automatic devices for protection of people against electric shock. SUBSTANCE: due to introduction of additional elements to the circuit of electronic devices of protective disconnection additional protective properties are attained, which provide in four-terminal networks TN-C-S the same electric safety as the best electromechanical devices for protective disconnection in five-terminal network TN-S or network TT. EFFECT: enhanced reliability. 2 cl, 3 dwg
