The invention provides a four-point type electrical equipment shock-absorbing method and a shock-absorbing system. The method comprises the following steps: acquiring parameters, wherein the parameters comprises the number n of preset absorbers, edge length of a square formed by four absorbers arranged in a square and symmetric manner, seismic fortification intensity and an attenuation ratio of seismic acceleration reaction, and n is equal to 4; acquiring mass, length, height of centre of gravity, elastic modulus and moment of inertia of electrical equipment, as well as a seismic influence coefficient corresponding to seismic fortification intensity and a site feature cycle corresponding to a design earthquake grouping and site classification in an electrical equipment installation site; determining limitation conditions of absorber parameters; selecting adaptive absorbers for the electrical equipment; and mounting four adaptive absorbers at the root of the electrical equipment in a square and symmetric manner, wherein edge length of the square of the four adaptive absorbers is equal to that of the square formed by the four absorbers arranged in a square and symmetric manner. According to the invention, a prospective shock-absorbing effect is realized with lower cost, and the seismic performance of the electrical equipment is improved.
