| Zusammenfassung: | The invention relates to a ship-shore oil conveying pipeline safety monitoring and emergency system, which comprises an emergency resistor, an insulating flange and a power supply, the flange measuring circuit is used for detecting resistance at two ends of the insulating flange; the first electronic change-over switch is connected with the flange measuring circuit and used for connecting or disconnecting the emergency resistor between the tail end of the ship side oil conveying pipe and the starting end of the shore side oil conveying pipe. When the resistance value of the insulating flange is larger than a first threshold value, the emergency resistor is connected between the tail end of the ship side oil conveying pipe and the starting end of the shore side oil conveying pipe through the first electronic change-over switch. According to the ship-shore oil conveying pipeline safety monitoring and emergency system, when the resistance at the two ends of the insulating flange is larger than the first threshol |
