Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a distribution board having an anti-

More particularly, the present invention relates to a switchboard having an earthquake-proof and anti-vibration function for vibration in horizontal and vertical directions, such as an earthquake, etc. [0003] 2. Description of the Related Art [0004] .

The switchgear is one of the electric power facilities, which consists of monitoring and control devices such as relays, instruments, and controllers, and main circuit devices such as breakers and disconnecting switches. Each unit device is mounted on the support structure for easy maintenance and repair.

However, if there is a problem in insulation or circuit durability because a high voltage is formed in the switchgear and a current flows, there is a possibility that a serious accident such as a fire may occur.

On the other hand, in addition to the above-mentioned circuit hazards, the switchgear often causes a serious accident such as a fire due to a physical shock such as an earthquake.

Due to the nature of the switchboard, not only circuit safety but also structural stability is very important.

Japanese Patent Application Laid-Open No. 10-0850228 discloses a switchboard having an earthquake-proof characteristic.

The distribution board of Patent Publication No. 10-0850228 is constructed so as to be spaced apart from the supporting upper plate and each pipe and spaced springs are disposed therebetween to mitigate the impact of the connecting members when the load path changes. The seismic resistance can be excellent, but the structure is very complicated and the manufacturing cost is also high.

In addition, JP-A-10-0850228 has an advantage that vibration can be effectively absorbed and cut off against an impact in the up-and-down direction, but has a disadvantage in that the vibration absorbing ability is relatively poor for the lateral vibration.

The seismic characteristics of Korea are mainly caused by the lateral vibration occurring along the ground rather than the vertical vibration and the lateral vibration causing cracks on the ground and causing more severe shock than the vertical vibration .

Therefore, it is necessary to strengthen the seismic resistance in the transverse direction unlike the existing switchboard, and it is necessary to strengthen the seismic resistance property with a smaller unit price and a simple structure.

An object of the present invention is to provide an electric distribution board having an anti-vibration and anti-vibration function.

The above and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, in which like reference characters designate the same or similar elements throughout the several views. A triangular steel piece welded to the horizontal surface and the vertical surface so as to be mutually supported in an inner angle direction of the vertical surface, An anchor bolt fixedly coupled to the anchor bolt and an anchor bolt hole for fixing the anchor bolt to the bottom surface of the rubber pad, and a panel rope band hole is formed on the vertical surface, Stopped; A lower horizontal surface and a vertical surface each of which is fixed to a quadrangular frame provided at an edge of an inner bottom plate of the power distribution board and is bent at an angle of 90 degrees to face the floor surface and the quadrangular frame, A rectangular flat plate formed on both upper and lower ends of the vertical plane and the upper horizontal plane, the rectangular flat plate being bent at 90 degrees toward the square frame and fixed to the rubber pad, And a rubber pad fixedly connected to the rubber pad fixing end, wherein the lower horizontal surface of the triangular steel piece is fixed to the lower horizontal surface An anchor bolt hole (not shown) for fixing the anchor bolt to the floor surface, a plurality of second stops in which a plurality of first stop portions are formed; Four third staples of a rectangular parallelepiped shape formed of a rubber material inserted between a base on which the switchboard is installed and an edge of the switchboard to reduce vibrations and shocks; And two panel rope bands secured to both ends of the panel rope band hole so as to be fixed to the upper ends of the switchboards.

Here, the second stop may be provided for each frame of the quadrangle frame provided at the edge of the inner bottom plate of the distribution board, and a total of eight may be provided.

The panel band rope is preferably made of a resilient rubber material.

According to the above-described switchboard having an anti-vibration and anti-vibration function of the present invention, it is possible to more effectively mitigate and absorb an impact caused by an earthquake using a simpler and less cost structure.

Particularly, since it is configured to absorb transverse vibration efficiently, it is useful for lateral vibration of earthquake mainly occurring in Korea, and absorption for longitudinal vibration is also good.

In addition, since a simple stop is installed in the switchboard, there is an advantage that the switchboard does not take up much space. Thus, it is easy to install a stop in addition to the existing switchboard. It is possible to easily provide the earthquake-proof characteristic without requiring a lot of cost and effort for the existing switchboards which are not designed for earthquake-resistant design.
