摘要： Provided is a circuit closer that: does not cause formation of projections, which may reduce the voltage withstanding performance between electrodes, on the surface of the electrodes even after a circuit closing operation; offers a larger number of possible operations than a pulse-type closer; and does not require a trigger electrode and a pulsed power supply.
The circuit closer comprises: a vacuum interrupter (1) in which one of a pair of electrodes (12A and 12B) oppositely disposed in a vacuum vessel (10) is provided so as to be capable of advancing and retracting relative to the other of the electrodes; and an operation device (3) for driving the one of the electrodes toward the other of the electrodes at a predetermined time, wherein a gap d between the pair of electrodes always satisfies d > 0, and a gap d1 between the pair of electrodes in a state in which closing of a circuit is completed, is shorter than a distance d2 at which insulation between the pair of electrodes is broken down by a charge voltage V of the circuit that is to be closed, and is longer than a distance d3 at which the pair of electrodes are bridged by a deposition of an electrode metal after a closing operation, the deposition resulting from evaporation caused by heat of an arc generated when the circuit is closed.

摘要： A DC circuit breaker includes: a mechanical switch (2) provided on an electrical path (1) through which a direct current flows; and a semiconductor switch (20) connected in parallel with the mechanical switch (2). The mechanical switch (2) includes a gas disconnector (3) and a vacuum circuit breaker (4) connected in series. Normally, the direct current flows through the mechanical switch (2). When interrupting the direct current, the vacuum circuit breaker (4) is made nonconductive to allow the direct current to be commutated to the semiconductor switch (20), and subsequently the gas disconnector (3) and the semiconductor switch (20) are made nonconductive. A vacuum circuit breaker (4) having a low withstand voltage can be used.
