1. can be used for the mechanical type DC circuit breaker of electric power or electronic system, it is characterized in that:

  • comprise whippletree body (1), supporting mass (2), connector (3), 2 electric rails (4), magnet (5), conducting liquid (6);

    Whippletree body (1) and supporting mass (2) are connected form gravity seesaw by being rotationally connected (12);

    Whippletree body (1) has the cavity volume (10) for holding conducting liquid (6), the fulcrum vertical line of the gravity seesaw that cavity volume (10) is formed with supporting mass (2) jointly across whippletree body (1);

    Conducting liquid (6) is loaded in the cavity volume (10) of whippletree body (1), and the volume of conducting liquid (6) is less than the half of the dischargeable capacity of the cavity volume (10) of whippletree body (1);

    The length of electricity rail (4) is less than the half of the lateral length of the cavity volume (10) of whippletree body (1);

    The fulcrum of the cavity volume (10) being arranged on whippletree body (1) that electricity rail (4) is paired is one-sided, between electricity rail (4) and electric rail (4), there is gap, between the end of the cavity volume (10) of electricity rail (4) and whippletree body (1), there is gap, between electricity rail (4) and whippletree body (1) fulcrum vertical line, there is interval, between paired electric rail (4), the both ends open in gap moves towards and whippletree body (1), the arm of force direction of the gravity seesaw that supporting mass (2) is formed jointly is consistent, very close to each other between the bottom surface of the cavity volume (10) of electricity rail (4) and whippletree body (1),Electricity rail (4) externally forms electricity passage via connector (3);

    Magnet (5) magnetic field line trend with gravity vertical move towards close, the end being mounted to right electric rail (4) passing through the cavity volume (10) of the whippletree body (1) at electric rail (4) place of the magnetic field line of magnet (5);

    Connector (3) is slip ring;

    Also comprise two be arranged in the cavity volume (10) of whippletree body (1) the end of electric rail (4) is not installed can jointly form the electrode of switch with conducting liquid (6);

    Also comprise circuit module and head station;

    Circuit module is that electricity is connected with the electrode that can jointly form switch with conducting liquid (6) not installing the end of electric rail (4) in the cavity volume (10) being arranged on whippletree body (1);

    Communicated by wireless telecommunications between circuit module with head station.
