APPARATUS FOR INDICATING GROUNDING ACCIDENT SECTION OF GAS INSULATION POWER EQUIPMENT

摘要

PURPOSE: An apparatus for indicating a grounding accident section of a gas insulation power equipment is provided to improve the detection accuracy of an accident section by detecting a decomposed gas generated by a corona and an arc through a decomposed gas sensor. CONSTITUTION: A conductor(10) is inserted into an inside of a closed vessel(1) filled with an insulation gas(2). The inserted conductor(10) is fixed on lateral ends of the closed vessel(1) apart by a space(3) so that the conductor(10) is located on an inner center of the closed vessel(1). A gas valve(6) connected to a gas pipe line(12) and a decomposed gas sensor(7) is installed on a hole formed on a side of the closed vessel(1). The decomposed gas sensor(7) is connected to a control panel(9) by a transmission line(8).
