Fuel-discharge protection system for preventing electrostatic hazard

摘要

A fuel-discharge protection system is provided herein to prevent electrostatic hazard when a tank truck is discharging fuel into a reservoir. This invention mainly contains an oil-valve switch device, a driving device, and an electrostatic detection and control device. The fuel is discharged from the tank truck into the reservoir through the oil-valve switch device. The electrostatic detection and control device monitors the ground resistance and the electrostatic voltage of the tank truck during the entire process of fuel discharge. The electrostatic detection and control device, by controlling the driving device, opens the valve of the oil-valve switch device to allow fuel discharged into the reservoir only when the ground resistance and the electrostatic voltage of the tank truck are within respective safety ranges.
