The invention relates to the technical field of high-voltage contactors, in particular to a safety protection system of a high-voltage contactor, which comprises a shell, a circuit cavity is formed in the shell, an electrifying mechanism is arranged in the circuit cavity and is used for receiving and conveying an electric arc, an electromagnetic cavity is formed in the upper side of the circuit cavity, and a protection mechanism is arranged in the electromagnetic cavity and is used for overload protection of the electric arc. A detection box is installed on the periphery of the shell, a detection cavity is formed in the detection box, a detection mechanism is arranged in the detection cavity and used for detecting the numerical value of transmission voltage and signal transmission, heat dissipation boxes are symmetrically arranged on the two side faces of the shell, a heat dissipation cavity is formed in the heat dissipation box, and a heat dissipation mechanism is arranged in the heat dissipation cavity and used for heat dissipation of work in the electromagnetic cavity. The high-voltage contactor is protected through the protection mechanism and the power-on mechanism, the problem that protection of the contactor is too single is effectively solved, damage caused by too large current fall generated during driving can be effectively prevented, and accurate detection can be made during maintenance.
