The invention provides a shock isolation device for an electrical device. The shock isolation device comprises a support body, a first elastic connection mechanism and at least two second elastic connection mechanisms, wherein the first end of the first elastic connection mechanism is connected with the support body; the second end of the first elastic connection mechanism is connected with a basic phase; each second elastic connection mechanism is arranged on the periphery of the first elastic connection mechanism in a surrounding way; each second elastic connection mechanism and the first elastic connection mechanism are arranged in a form of an include angle; the first end of each second elastic connection mechanism is rotatably connected with the support body; the second end of each second elastic connection mechanism is rotatably connected with the basic phase; the support body is connected with the electrical device. According to the shock isolation device for the electrical device provided by the invention, the shock isolation device has accurate zero stiffness and can be used for carrying out shock insulation on low-frequency earthquakes, meanwhile, the earthquake force stressed on the electrical device is smaller, and the anti-seismic property of the electrical device is effectively improved.
