VERTICAL SYSTEM FOR SEISMIC RETROFIT OF ELECTRIC/ELECTRONIC CONTROL EQUIPMENT

摘要

PURPOSE: A vertical system for seismic retrofit of electric/electronic control equipment is provided to prevent damage of internal components by installing an additional system for seismic retrofit at a control cabinet and a distribution board. CONSTITUTION: A top load(110) is formed with a shape of a cylinder. A top load is formed with a shape of a plate. One end of the upper rod is fixed and coupled to a ceiling slab of a building. A hydraulic damper(120) is rotatably combined with an end of the top load. A hydraulic damper includes oil and a spring in the inside thereof. One end of a lower rod(130) is combined with an electronic device. The other end of the lower rod is located in the inside of the hydraulic damper.
