Title:
GAS-BLAST CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2010/041455
Kind Code:
A1
Abstract:
It is possible to avoid the difference between the gross amount of used gas and the sum of a plurality of amounts of variation that the gas-blast circuit breaker holds. The gas-blast circuit breaker comprises a flow detection unit (11), a flow calculation unit (12), a fluctuation calculation unit (13), a fluctuation determination unit (14), a valve driving unit (15), a valve (16), a fluctuation correction unit (17), and a constant fluctuation correction unit (18). The fluctuation determination unit (14) acquires the corrected amount of variation (G) from the fluctuation correction unit (17) or the constant fluctuation correction unit (18) and adopts the corrected amount as the new amount of variation (C), to thereby prevent the elongation in the time period for using the gas until a gas passage is closed.
