INTERFACE FOR INTERCONNECTING CIRCUIT BREAKER AND SURGE ARRESTER, SURGE ARRESTER INCLUDING SUCH INTERFACE AND SELF-PROTECTED ELECTRICAL DEVICE COMPRISING SURGE ARRESTER AND CIRCUIT BREAKER INTERCONNECTED BY SUCH INTERFACE

摘要

The invention relates to a breaker and arrester interconnecting interface (100) comprising the following elements: a switch (110) connected with a connector (120) sending representation breaker and/or arrester running state signals; a machinery part (130) connected with the breaker and moving between a wrench position and a disconnect position respectively matched with a connecting state and a disconnecting state of the breaker, and used for actuating the breaker in the disconnect position. The interface comprises another machinery part (140) connected with the arrester and moving between the a stop position and a disconnect position respectively matched with a normal running state and a default setting state of the arrester, and is positioned on the path of the first part in the disconnect position and capable of actuating the breaker.
