The invention provides an electrical equipment seismic isolation device which comprises a pool body, a supporting mechanism and a limiting mechanism, wherein the pool body is embedded into a foundation; the supporting mechanism and the limiting mechanism are placed in the pool body; the bottom end of the supporting mechanism is connected with the bottom wall of the pool body; the top of the supporting mechanism is slidingly connected with electrical equipment; one end of the limiting mechanism is connected with the bottom wall of the pool body; the other end of the limiting mechanism is connected with the electrical equipment; and the limiting mechanism is used for limiting the displacement of the electrical equipment on the supporting mechanism. According to the electrical equipment seismic isolation device, the electrical equipment can slide freely along the supporting mechanism in the pool body and consumes a part of seismic energy, and when the vibration is great, the limiting mechanism in the pool body may prevent the electrical equipment from being separated from the supporting mechanism, so that the seismic response of the electrical equipment is reduced, the electrical equipment is protected from being damaged by an earthquake, and a damage rate of the box type electrical equipment in an earthquake is reduced. The complete electrical equipment seismic isolation device is convenient to mount, and a seismic isolation function is easy to realize.
Description
technical field [0001] The invention relates to the technical field of power systems, in particular to a vibration isolation device for electrical equipment. Background technique [0002] At present, the seismic design of different regions is carried out according to the seismic zoning map and national standards. Considering that earthquakes are unpredictable and extreme geological disasters, the damage rate of box-type electrical equipment in substations is extremely high when earthquakes occur. The box-type electrical main equipment in the substation itself is heavy, such as the main transformer and high-resistance, etc. When an earthquake occurs, the main electrical equipment may leave its original position, shift or fall off. In addition, the casing on the equipment body is a weak link that is prone to damage, and the root of the porcelain casing often breaks or shifts under the action of a large earthquake. Once the electrical equipment breaks away from the foundation ...
