VOLTAGE DETECTING DEVICE FOR PREVENTING ELECTRIC SHOCK BY DETECTING VOLTAGE APPLIED TO MAIN LINE OF DISTRIBUTING BOARD SUCH AS HIGH-VOLTAGE DISTRIBUTING BOARD, LOW-VOLTAGE DISTRIBUTING BOARD, MOTOR CONTROL CENTER AND SWITCHBOARD

摘要

The present invention relates to a voltage detecting device of a distributing board for preventing an electric shock by detecting voltage applied to the main line of a high-voltage distributing board, a low-voltage distributing board, a motor control center and a switchboard and, more specifically, to a voltage detecting device of a distributing board capable of not only detecting high voltage applied to the main line of a high-voltage distributing board but also detecting low voltage applied to the main line of a low-voltage distributing board, a motor control center and a switchboard. For the purpose, the voltage detecting device of a distributing board for detecting voltage applied to the main line of a distributing board comprises: a voltage distributing part connected to a first main line having high voltage applied thereto and distributing the voltage applied to the first main line into at least two voltages; a set voltage restricting circuit part for receiving one voltage distributed by the voltage distributing part or receiving voltage applied from a connected second main line and restricting the received voltage to having a set size of voltage; a rectifying part for rectifying voltage provided from the set voltage restricting circuit part; and a voltage dropping part for dropping voltage provided from the rectifying part to a set voltage or lower.;COPYRIGHT KIPO 2016
