Distribution Board with Earthquake-Proof Device used Steel BallHigh-voltage Switchgear Low-voltage Switchgear Motor Control Center Cabinet Panel

摘要

The present invention relates to a water switchboard (high voltage board, low voltage board, motor control panel, distribution panel) equipped with a seismic device using a steel ball capable of effectively reducing vibration in the horizontal direction transmitted to the water switchboard due to an earthquake or the like. The seismic device of a switchgear equipped with a seismic device using a steel ball according to the present invention for solving the above problems, a base plate having a predetermined size in which a long hole is formed, and a protrusion having a predetermined height on an upper surface of the base plate A lower bracket including an installation part in which three or more fastening holes are formed radially on an outer surface while receiving grooves having a predetermined size are formed therein; Located in the upper portion of the lower bracket, the bottom surface is opened to form a contact surface of a predetermined size inside, and a cylindrical housing in which a plurality of guide holes are formed along the outer surface, and one end is fixed to the upper surface of the housing and the other end is vertically An upper bracket including a fastening bolt formed to protrude upward a predetermined length; A steel ball having a predetermined diameter inserted into the installation portion and installed to contact the contact surface; And one or more elastic support members having one end screwed to the fastening hole and the other end passing through the guide hole to have a horizontal length to elastically support the upper bracket.
