The invention provides an oil tank overfilling protective system and a working method thereof. The oil tank overfilling protective system comprises a first oil cavity communicating with an oiling pipeline, a second oil cavity communicating with an oil tank, a partition plate for separating the first oil cavity from the second oil cavity, and the partition plate is provided with a communicating port used for communicating with the first oil cavity and the second oil cavity. The oil tank overfilling protective system further comprises a piston device capable of closing or opening the communicating port, and a control device for controlling action of the piston device; and when the liquid level of the interior of the oil tank reaches the highest liquid level, the control device drives a piston to act, and thus, the communicating port is closed. Automatic oiling of the oil tank can be achieved, overfilling is avoided, and the reliability is high. 本发明提供了一种油罐加油过满保护系统及其工作方法，油罐加油过满保护系统包括与加油管路连通的第一油腔、与油罐连通的第二油腔、用于间隔所述
