<p><P>PROBLEM TO BE SOLVED: To provide an opening and closing control system for a circuit breaker which can be easily connected to an external device such as a personal computer or the like in a site or from a remote area, without using a dedicated software and can efficiently perform maintenance and data collection. <P>SOLUTION: The opening and closing control system for a circuit breaker is constituted of: an opening and closing control unit 100 for one or more circuit breakers, which input at least one electric amount of either system voltage or main circuit current and a state amount of the circuit breaker and at least one signal of either the pole-opening command signal or the pole-closing command signal of the circuit breaker to perform interruption control or connection control; and a display operation part 700, which is connected to the opening and closing control unit via a communication network 500 for monitoring the operation and the state of the opening and closing control unit. The system further includes a first area 110 as an opening and closing control computing means for interrupting or connecting the circuit breaker at a desired phase of the system voltage or the main circuit current and a second area 120 as a communication computing means for receiving/transmitting the information from the display operation part or for transmitting the information in the first area via the communication network. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
