| 发明名称 | Method for controlling gap in circuit breaker | ||
| 摘要 | Disclosed is a method for controlling a gap in a circuit breaker, the circuit breaker configured to interrupt a circuit by separating a movable contactor from a fixed contactor as a cross bar is pressed to be rotated by a pressing member due to bending of a bimetal, the method including: a gap forming step of bending the bimetal by apply of a set current, in a state where the pressing member is coupled to a coupling hole so as to be freely-movable, the coupling hole formed at an upper part of the bimetal; and a gap fixing step of interrupting the set current when a prescribed time has lapsed, and of welding the pressing member to the bimetal. | ||

| 主权项 | 1. A method for controlling a gap in a circuit breaker, the circuit breaker configured to interrupt a circuit by separating a movable contactor from a fixed contactor as a cross bar is pressed to be rotated by a pressing member due to bending of a bimetal, the method comprising: a gap forming step of bending the bimetal by apply of a set current, in a state where the pressing member is coupled to a coupling hole so as to be freely-movable, the coupling hole formed at an upper part of the bimetal; and a gap fixing step of interrupting the set current when a prescribed time has lapsed, and of welding the pressing member to the bimetal. | ||
