    • A time-delay switching device which includes a pneumatic timer adapted to be triggered by an electromagnet. The switching device includes at least two switches, with each switch including a movable switching element for controlling switching operations in, for example, a wye-delta control circuit. The time delay switching device is constructed in such a fashion that a specified switching pause occurs between an actuation of the two switches and/or an actuation of a second group of switches. One of the switches includes a movable switch element which is influenced immediately after the expiration of a time delay period by the pneumatic timer. A movable switching element of the other switch is coupled with the first switching element by a buffer which is adapted to transmit a switching movement on a delayed basis. The buffer may take the form of a mechanical or pneumatic compression spring.
    • 一种延时切换装置,其包括适于由电磁体触发的气动计时器。 开关装置包括至少两个开关,其中每个开关包括用于控制例如八叶形三角洲控制电路中的开关操作的可移动开关元件。 时间延迟切换装置构造成使得在两个开关的致动和/或第二组开关的致动之间发生指定的切换暂停。 其中一个开关包括可动开关元件,其通过气动计时器在时间延迟周期期满之后立即受到影响。 另一个开关的可移动开关元件通过缓冲器与第一开关元件耦合,该缓冲器适于以延迟的方式发送切换运动。 缓冲器可以采取机械或气动压缩弹簧的形式。
