ROTATIONAL VIBRATION ABSORBING DEVICE FOR AN EARTHQUAKE-PROOF FUNCTION OF A HIGH/LOW VOLTAGE DISTRIBUTION BOARD, A MOTOR CONTROL BOARD, AND A CABINET BOARD WHICH IS CAPABLE OF PREVENTING POWER FAILURE

摘要

PURPOSE: A rotational vibration absorbing device for an earthquake-proof function of a high/low voltage distribution board, a motor control board is provided to absorb vibration to minimize impact by vibrating, thereby safely protecting electricity receiving facilities.;CONSTITUTION: The bottom surface of a fixing base(102) adheres closely to the ground. The fixing base has a ball separation prevention unit(101). An impact and vibration absorbing unit(111) is inserted into the outer circumferential surface of a ball bearing bolt. The impact and vibration absorbing unit which is placed in a spring container absorbs or buffers impact and vibration. A horizontal gimbals unit(122) is located on the upper part of the impact and vibration absorbing unit.;COPYRIGHT KIPO 2013
