Description
The present invention minimizes the vibration energy transferred from the transformer 1 as well as minimizes the behavior of the transformer 1 according to the behavior of the ground and easily verifies the positional change between the transformer 1 and the vibration- To a vibration-damping support device of a substation transformer capable of quick maintenance.
A typical substation is a collection of facilities that are installed for the modification of voltage and current and the distribution of electric power in the process of sending electric power produced by a power plant to a demander through a transmission line and a distribution line.
Examples of facilities installed in such a substation include a transformer (1), a disconnector, a circuit breaker, an ancillary equipment, a lightning arrester, or an electric switchboard.
Although the transformer (1) of the substation is a key device for supplying electricity, complaints by the residents around the substation are frequent because of the characteristics that cause a lot of noise. Therefore, for a substation operator, development of techniques for reducing the vibration of the transformer 1 is a very important technique in terms of environmental noise reduction.
Conventionally, a substation transformer is installed on a floor of a foundation part, which is usually made of concrete, without a separate device, so that vibration from the transformer 1 or the transformer 1 is transmitted between the transformer 1 and the concrete foundation part do.
Therefore, when the vibration from the transformer 1 is transmitted to the base portion because no separate vibration reduction device is provided, the vibration is transmitted to the vicinity of the substation so that the shape destruction due to the vibration of the surrounding structure, Problems such as complaints caused by noise generation occurred. In addition, when vibrations generated in the base portion, for example, vibrations generated by automobile operation, vibrations generated by earthquake or the like are transmitted to the transformer 1, the transformer (1) 1), and the like.
Therefore, there is a demand for a vibration preventing technique that removes the vibration caused by the operation of the transformer 1 and the vibration from the ground that is transferred toward the transformer 1.
An anchor bolt for placing and fixing the transformer 1 on the ground is interposed between the transformer 1 and the ground on the lower end of the transformer 1. The earthquake and dustproof technique applied to the conventional transformer 1 will be described.
In the case of simple fastening by such an anchor bolt, vibration due to an earthquake is directly transmitted to the transformer 1, which may damage or damage the transformer 1.
Alternatively, a vibration-
