DECLENCHEUR ELECTRONIQUE POURVU D'UN CIRCUIT D'ALIMENTATION COMPORTANT DES MOYENS REHAUSSEURS DE TENSION ET DISJONCTEUR COMPORTANT UN TEL DECLENCHEUR |
摘要 |
The device has a rectifying circuit to rectify a secondary current supplied by current sensors (T1-T3) and to supply a supply current (la). An electric power supply circuit has a storage capacitor (16) to electrically supply an actuator, and a voltage regulator (17) to supply a supply voltage (VA) to an electronic processing unit (6). The capacitor is charged by the supply current. The supply circuit has a resistor (19) and a voltage-limiting diode (20), to supply a raised voltage (VB) to the input of the regulator. The voltage (VB) is greater than a voltage (VM) at the capacitor terminals. The secondary current supplied by the current sensors is representative of a primary current in a main conductor of a circuit breaker. An independent claim is also included for a circuit breaker equipped with an electronic trip device. |
