SPRING-OPERATED MECHANISM HAVING DELAY CIRCUIT |
摘要 |
A hydromechanical stored-energy spring mechanism is provided for operating at least one switching contact of a circuit breaker, for example, in a high-voltage switching system. The hydromechanical stored-energy spring mechanism includes a hydraulically operated close-open (CO) delay circuit configured to delay triggering of a switching process of the circuit breaker, and an electromechanical actuator provided in place of a hydraulic operation of the CO delay circuit. The electromechanical actuator generates a mechanical time delay or acceleration over an extended temperature range. |
