摘要（英）：

The invention relates to a fully sealed oil-paper insulated nitrogen charging long-term storage test device and method. The fully sealed oil-paper insulated nitrogen charging long-term storage test device comprises a device main body, a gas pressure indicator, a valve, an external winding heating belt, a bracket and a screw rod, wherein the device main body is provided with a three-electrode measuring device, a sealing cover plate, a PTFE shell, a base, a gas valve, an oil valve and a temperature sensor; the three-electrode measuring device comprises a high-pressure electrode, a measuring electrode and a protective electrode; the sealing cover plate is provided with a sealing ring, which is fixed and sealed with the screw rod to realize the sealing of the device; the gas valve and the oilvalve cooperate with each other to realize the nitrogen charging long-term storage of a sample in the device; and the gas pressure indicator and the temperature sensor can monitor the nitrogen pressure and temperature during long-term storage, and can realize temperature control during storage in cooperation with the external winding heating belt. The fully sealed oil-paper insulated nitrogen charging long-term storage test device and method are used for realizing the nitrogen charging long-term storage of oil-paper insulation, and study the influences of different influencing factors on the nitrogen charging long-term storage.
