Title:
IMPACT PRESSURE RELAY
Document Type and Number:
Japanese Patent JP2002078127
Kind Code:
A
Abstract:
To provide an impact pressure relay which enables saving power and also performing reliable SP detection.
An impact pressure relay 1 is connected to a pressure introduction pipe 3 of a GIS 2 pressure container 2C. In the impact pressure relay 1, a first processing step, which monitors pressure change at plural predetermined time intervals, and a second processing step, which monitors pressure change at a time interval shorter than that of the first processing step, are executed. When any pressure change is detected in the first processing step, the second processing step is performed. The operating clock of a microcomputer is controlled so as to be low in the first processing step and high in the second processing step.
