    • Blow-out device for an electromechanical DC circuit breaker especially for protection of DC installations in a main circuit, comprising a fixed contact element (5) and a moving contact element (6) which under normal conditions are in electrical contact with each other carrying the full current of the main circuit and which moving contact element (6) when some predefined condition is detected in the main circuit which according to the applied strategy should result in a cut off of the main current is caused to be withdrawn from the mechanical and thereby the electrical contact with the contact element (5). The device is provided with a pair of electrodes (12) electrically connected to the moving contact element (6) through a magnetising coil (8) arranged on both sides of the trajectory for the element (6). And said magnetising coil (8) when energised by means of a magnetic circuit including at least one pair of pole pieces (9) is arranged to create a magnetic field in the space between the fixed and the moving contact elements for driving the arc into a co-operating arc-chute (1).
    • 一种用于机电式直流断路器的吹出装置,特别用于保护主电路中的直流安装,包括固定接触元件(5)和可移动接触元件(6),其在正常条件下彼此电接触,承载着 在主电路中检测到主电路中的某些预定条件时,主电路的全电流以及根据应用策略导致的主电流的切断被导致从机械中撤出,从而 与接触元件(5)的电接触。 该装置设置有一对电极(12),电极通过布置在用于元件(6)的轨迹的两侧的磁化线圈(8)电连接到可移动接触元件(6)。 并且,所述磁化线圈(8)当通过包括至少一对极片(9)的磁路被激励时,被布置成在固定和可移动接触元件之间的空间中产生磁场,用于将电弧驱动到 合作电弧槽(1)。
