Description

{SWITCHGEAR HAVING A REINFORCED EARTHQUAKE-PROOF FUNCTION}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ASSEMBLY, and more particularly, to an ASSEMBLY for enhancing an earthquake-proof function for protecting an ASSEMBLY installed in a substation, power generating facilities, various buildings, public facilities, .

Generally, the magnitude of the seismic force that affects the building when an earthquake occurs varies depending on the structural characteristics such as the height, shape or material of the building, and the earthquake can have a greater influence on the advanced equipment installed on the building floor .

In areas such as industrial information processing control equipment, OA equipment and related facilities, where online / real-time processing systems are required, especially in fields with high publicity such as power, nuclear power, water treatment, aviation and railroad, The demand for it is getting higher.

In addition, earthquake disaster countermeasures (Law No. 9636) and earthquake disaster countermeasures enforcement ordinance (Presidential Decree No. 21362) require mandatory seismic measures for all public buildings and facilities.

In addition, mechanical vibrations occur due to vibration of the floor or electromagnetic force in the ordinary case where an earthquake does not occur. In such a case, vibrations are transmitted to the cabinet itself, and expensive high-end devices installed inside the cabinet are damaged. Occurs.

As a result, the switchboard installed on the floor of the building must be equipped with not only dustproof performance but also seismic performance.

However, the conventional structure has a problem that it is very vulnerable to an earthquake because it is a dust-proof structure separating the vibration source and the switchboard by attaching a spring or a rubber pad under the switchboard for vibration isolation.

On the other hand, in the prior art of the present invention, a "switchboard apparatus having an isolation system" of the patent registration number "10-1305302" is filed and registered. The switchboard apparatus having the isolation system includes a switchboard A controller for generating a control signal in accordance with the detection result of the sensor; and a controller for generating a control signal based on the electric power supplied to the electric power source from the electric power source And a main switching unit having a first terminal connected to the isolation device and a second terminal electrically connected to the isolation device and switching a power source supplied to the isolation device according to a control signal from the controller.

However, since the floor surface on which the seismic isolation device and the switchboard are installed is not fixed, the switchboard apparatus having the above-mentioned isolation system may be able to conduct the switchboard when the earthquake occurs, or to deviate from the position where the switchboard is installed.

In addition, there is a problem that when the electric power is cut off in the event of an earthquake, the electric circuit for driving the isolation device is not operated and the isolation device can be stopped.

Korea Patent Registration No. 10-1282201 (2013.07.04) Korea Patent Registration No. 10-1269899 (May 31, 2013) Korea Patent Registration No. 10-1305302 (2013.09.06)

Accordingly, an object of the present invention is to provide a switchgear having an improved seismic function capable of safely protecting an interior of an ASSEMBLY or an ASSEMBLY from internal vibration caused by floor vibration, mechanical vibration, or earthquake transmitted to an ASSEMBLY, .

In order to accomplish the above object, the present invention provides a switchgear having enhanced seismic function, comprising: a transverse direction rail piece laid down in a lateral direction; and one end portion fixedly coupled to one end of the transverse direction rail piece, And an upper anchor bolt which is fixedly connected to the bottom surface of the switchboard through an anchor bolt, and the shock due to the earthquake is transmitted to the lower end of the switchboard, A triangular earthquake-proof means that attenuates the impact transmitted to the switchboard as it is contracted or expanded elastically, a tie-breaker steel wire with both ends facing each other in the vertical direction of the switchboard, a triangular earthquake-resistant means and an anchor bolt, And a wire for preventing the wire from being changed, As the elastically deformed or restored when in the deployed state due to the earthquake shock is transmitted to the panel board it may be formed of a resilient iron piece to attenuate the impact transmitted to the switchboard.

An earthquake-resistant switchboard having such a structure according to the present invention can safely protect the equipment inside the switchboard or the switchboard from internal shocks caused by floor vibration, mechanical vibration, or earthquake transmitted to the switchboard.

In addition, the present invention can more efficiently absorb shock caused by earthquakes by using a structure that is simpler in structure and lower in unit price than the existing structure.

In addition, since the present invention having an earthquake-proofing function can be simply mounted on an existing switchboard not subjected to earthquake-resistant design, it is possible to provide an earthquake-proof property to an existing switchboard without requiring much expense and effort.

Further, according to the present invention, by mounting the triangular earthquake-resistant means on the lower four corners of the switchboard, the triangular earthquake-proof means can be elastically contracted or expanded when the earthquake occurs, so that shocks transmitted to the switchboard can be buffered.

In addition, when the navigator steel pieces are brought into contact with the upper horizontal bar and the upper vertical bars on the upper portion of the switchboard, and then the navigator steel pieces are fixed to the upper vertical bar and the upper vertical bar, It is possible to prevent deformation.

Further, by connecting the navigator steel piece and the triangular earthquake-resistant means through a wire in a resilient manner, it is possible to prevent the switchboard from being conducted or disengaged from the installation position.
