Abstract
PURPOSE: To accomplish accurate detection of short-circuit, if any, in the power switch by detecting current running through a high voltage conductor contained in the closed metal vessel with a current transformer, a light emission element and a photo detector.
CONSTITUTION: A high voltage conductor 2 is contained in a closed metal vassel 1. A through type current transformer 3 is mounted to the high voltage conductor 2 insulated at the same potential as the conductor 2. A light emitting device 5 is fixed to the section to which the through type current transformer is bounded. As opposed to the light emitting device 5, a photo detecting device 6 having a photo detector is installed to a given point of the closed vessel 1. The electric signal is indicated on a display unit after amplified by an amplification circuit.
