Description

Technical Field

[0001] This utility model relates to the field of differential protection device technology, and more specifically, to an optical fiber differential protection device that effectively protects against plug detachment. Background Technology

[0002] Fiber optic differential protection uses phase-separated current differential elements as fast main protection and employs PCM optical fiber or cable as the channel, enabling faster operation and making it the primary protection for short-circuit lines. The difference between fiber optic differential protection and other differential protection methods lies in the channel configuration. Longitudinal protection channels generally include the following types: power line carrier longitudinal protection (also known as high-frequency protection); microwave longitudinal protection; fiber optic longitudinal protection; and guide wire longitudinal protection. However, the connections in fiber optic differential protection are often prone to detachment or poor contact, causing the differential protection device to malfunction and fail to protect the equipment.
