The invention provides a shock isolation device for electrical equipment, comprising a shock isolator, a first connecting plate, a second connecting plate and limit devices; wherein, the shock isolator is arranged between the first connecting plate and the second connecting plate, and the first connecting plate is used to connect the electrical equipment; the second connecting plate is used to connect a base; the limit devices are connected to the base, and a preset distance is provided between the limit devices and the first connecting plate; the limit devices are used to limit the horizontal displacement of the shock isolator in multiple directions. In the invention, the limit devices can be used to limit the horizontal displacement of the shock isolator in multiple directions, so that the continuous limit of the shock isolator in all directions is achieved, the horizontal displacement of the shock isolator is limited within the preset range, and the shock isolation effect is improved greatly; in addition, the limit devices can be used to disperse the acting force of the first connecting plate, the limit devices are prevented from being damaged, and the shock isolation device is excellent in integrality and convenient for implementation.
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, electrical equipment is an important part of transmission lines. Correspondingly, people pay more and more attention to the anti-seismic ability of electrical equipment. For example, transformer-type electrical equipment in substations, such as transformers and high-voltage reactors, etc., these electrical equipment are large in size, relatively low in the center of gravity, and their natural vibration frequency is above the excellent frequency of earthquake vibrations, so it is easy to cause electrical damage to equipment. [0003] In order to avoid damage to electrical equipment caused by earthquakes, shock isolators are generally used to improve the seismic performance of electrical equipment. The shock isolator is installed between the electrical equipment and the foundati...
