Static discharge is a phenomenon in which, when the field intensity around a charged body exceeds the dielectric breakdown field intensity of the surrounding medium, the medium is ionized, and the charge on the charged body is partially or completely eliminated. The civil aircraft is pressurized to refuel due to large fuel consumption, complex design structure of an oil tank and short-time filling of large-tonnage fuel. The fuel oil can generate static electricity and store electricity when moving relative to the solid surface, and can generate discharge phenomenon when the potential difference reaches 20KV, and the spark energy is 0.2 megacoke greater than the minimum ignition energy of the fuel oil or the concentration of fuel oil steam in the air is in the explosion limit range, so that explosion can occur. The phenomenon is easy to occur within 1-2 minutes from the beginning of the pressure refueling of the aircraft, and the timely elimination of static electricity generated in the refueling process of the aircraft is of great importance to all systems and safety of the aircraft.

The tank type refueling truck is provided with an oil tank which can independently complete pressure refueling (oil pumping) of the aircraft, and the pipeline refueling truck can independently complete refueling of the aircraft through a apron pipe network. The pressure control system of the refueling truck ensures that the pressure at the tail end of the refueling pipe is not more than 0.35MPa, the flow rate of fuel in the pipeline is not more than 9m/s, and the flow rate of the fuel entering the fuel tank port is not more than 3m/s. The aircraft refueling mode comprises the following steps: pressure filling and gravity filling, the full tank pressure filling is accomplished for example at a330 for approximately 33 minutes. Aviation fuel has a strong ability to accept charge (high charge tendency) and a low ability to discharge charge (low conductivity). The antistatic agent is added into the fuel oil to improve the conductivity, so that the electrostatic charge generated in the fuel oil is rapidly conducted. The conductivity of fuel provided by civil airports is generally not lower than 70pS/m. The electrostatic grounding and the bridging are effective methods for eliminating static electricity in the process of airplane refueling, and the electrostatic grounding means that a refueling truck is respectively bridged with an airplane grounding column (grounding sheet) and ground grounding through a metal wire when an airplane refuels, so that the refueling truck, the airplane and the ground form an electrical potential body, and electrostatic charges generated in fuel oil of the airplane and the refueling truck are released.
The electric potentials of the airplane and the refueling truck are equal through grounding, and the disaster caused by the discharge phenomenon caused by the electrostatic potential difference is avoided. The oiling vehicle is provided with an electrostatic grounding reel and a grounding wire with a jointing clamp, and the bottom of the vehicle body is provided with an electrostatic mopping adhesive tape. The fuel filler pipe of the fuel truck is a metal pipe, any two points or any point of the fuel filler pipe reach the tail end of the grounding wire, and the resistance value of a conductive path from the grounding wire to the tail end of the mopping adhesive tape is not more than 10 omega. Before equipotential refuelling, the refuelling truck should lead the static electricity line and link to each other with the airborne vehicle equipotential, during the refuelling operation, must not remove the static electricity of leading of refuelling truck and airborne vehicle and connect, can remove after the refuelling truck pipeline separates with the airborne vehicle. Although a strict operation flow system is specified, manual operation cannot avoid missing inspection steps due to human negligence.
