Abstract

PURPOSE:To prevent an accident from being generated, by judging the normal or abnormal state of the gas pressure of an objective gas section from information on the switching condition or the like of earth switches and stop valves. CONSTITUTION:Micro-computer boards 14 are arranged at every gas sealing section in the control box of a gas insulated electric apparatus, and the connecting relation of various apparatus in the section, a relation between a pressure switch 12 and stop valves 10A, 10B, and the like are previously stored, and signal or the like for showing the switching states of the stop valves 10 and an earth switch 7B and the state of sealing pressure with the pressure switch 12 is introduced. Input signal to the boards 14 is processed via a signal processing section 14A and an intelligence process judging section 14B, and output from a terminal 15 is used for command signal for locking the operation of earth switches 7A-7D. Then, the items of information are combined with each other, and the existence of insulating gas in the sealing section is detected, and when sufficient gas is not sealed in, then the earth switches in relation to the section are locked not to be released.
