The present invention relates to a vibration control-type earthquake-resistant distribution board employing a steel body mode absorbing vibration according to a weight of a component device, and more specifically, to an earthquake-resistant distribution board having a vibration control effect by misaligning with a predominated period range of an earthquake from a viewpoint that natural frequencies of devices in a distribution board are different by weights, shapes, and positions. The vibration control-type earthquake-resistant distribution board employing a steel body mode absorbing vibration according to a weight of a component device according to the present invention comprises special devices which absorb a vertical and a horizontal vibration impact for a circuit breaker, a current transformer, a bus bar, etc in a distribution board to demonstrate earthquake-resistant performance, comprises an accessory device for each device in the distribution board which absorbs a shock wave transferred from a frame of the distribution board to improve resistance to vertical and horizontal vibration to demonstrate the earthquake-resistant performance, and demonstrates a sufficient earthquake-resistant effect even when a steel body lighter and less strong than a conventional earthquake-resistant distribution board is used. Additionally, an internal structure of the conventional distribution board is maintained and the special devices are used to fix the devices in the distribution board to facilitate simple installation, and can be applied to a general distribution board such as an extra high voltage board, a high voltage board, a low voltage board, a motor control center (MCC), a panel board, etc. without limitations. |
