A SYSTEM AND METHOD FOR DETECTING FAULTS OF GAS INSULATED SWITCHGEAR

摘要

The present invention relates to a system and method for determining a fault interval of a gas insulated switchgear (GIS). The gas insulation switchgear failure section determination system according to the present invention, the pressure switch for detecting the rate of change (ΔP / Δt) of the pressure rise in the gas insulation switchgear operating the built-in switch and generates an operation signal indicating the switch operation ; And a circuit breaker that operates in an open state and generates a mechanical contact signal indicating an open state in the event of a failure of the gas insulated switchgear, and includes a failure of the gas insulated switchgear using an operation signal of the pressure switch and a mechanical contact signal of the circuit breaker. Determine the section. In addition, the gas insulation switchgear failure interval determination method according to the present invention comprises the steps of detecting the low-pressure alarm through the gas pressure gauge by the central control equipment; Detecting, by the central control equipment, mechanical contact of the breaker; And determining, by the central control facility, whether the GIS has failed from the low pressure alarm and the mechanical contact operation of the breaker.
