Diesel engine overspeed protection system and method

摘要

the present invention is a power failure (Black-out) and UPS to a total loss (total loss), even if the status of the battery and additional latch type solenoid valve used in the local control panel and control panel to the governor to supply a driving power normally to control a diesel engine, or on the overspeed phenomenon prevention system and method for a diesel engine to safely stop the diesel engine, supplies the DC power received charge, and the charged direct-current power supply when the direct-current power is cut off the release of feed the uninterruptible power supply for direct current with a battery for supplying a direct current; If the supply and take charge, AC power supply is cut off the release of the AC power source AC uninterrupted power supplies for supplying alternating current power charged; A local control panel for outputting by converting the DC power supplied from the uninterruptible power supply of direct current to the engine shutdown control voltage; And provided with a standby power supply, AC uninterruptible power supply converts the AC power supplied from the device to the governor actuator control voltage to output, and if that is the AC power is supplied from the alternating-current uninterruptible power supply for parts of the emergency power supply for governor actuator control panel to the governor supplying a control voltage via the actuator; And in response to the engine shutdown control voltage of the local control panel provided with a first solenoid valve for emergency stop Soleil shutdown the diesel engine and which includes a. Accordingly, there is an effect that allows to avoid breakage phenomenon of the diesel engine in advance. ;
