Gas insulated switchgear accident segment detection device

摘要

(57) Abstract Objective With former accident orientation manner it to be possible to detect,With the fact that slight accident such as brief it is not ground is detectedThe GIS accident interval detection device which finishes is offered. Constitution The light which detects the arc light inside GIS11 - 23Sensor the light where converts the optical output from P11 - P23 to the electric informationElectric converter 32, is enclosed inside GIS the switch CB1 whichAssistantThe contact input section 33 where opening and closing state of the contact breaker points of the help switch is input,The time of accident conservation rire which trip it can point the breaker of GIS- The conservation relay contact where the trip command which is output is inputFrom entry section 34, and logical decision section 35 GIS accident interval detectionTo form device 31, the logical decision section appear from the aforementioned photoelectricity converterWhen power is done, aforementioned contact input section and aforementioned conservation rire- From opening and closing state of each contact breaker points in the contact input section generation of accidentAnd accident interval is detected.
