PASSIVE OPTICAL FIBER SWITCH OF INTELLIGENT TRANSFORMER SUBSTATION AND SAFETY MEASURE ISOLATING METHOD THEREOF

摘要

Disclosed are a passive optical fiber switch of an intelligent transformer substation and a safety measure isolating method thereof. A passive optical fiber switch comprises an optical fiber collimator. At two ends of the optical fiber collimator, two optical fiber adapters are partially embedded in the optical fiber collimator. The optical fiber adapters are connected to optical fibers. A blocking plate is arranged in the optical fiber collimator. The blocking plate divides the optical fiber collimator into a left part and a right part, and a trigger switch is connected to the blocking plate. The present invention overcomes the defect of poor visibility of a soft pressing plate in safety measure isolation, and eliminates a risk of error wiring caused by plugging and pulling optical fibers for safety measure isolation and a hidden risk of damage to an optical fiber interface. No operation of an electronic device is needed, so as to eliminate the influence of interference from an external electromagnetic field, and provide high reliability. Same as a safety measure method of a conventional transformer substation, an obvious disconnection point is provided. The safety measure isolating method is simple and convenient to implement and restore, satisfies safety requirements of conventional repair and maintenance, and improves working efficiency, reliability and safety.
