Abstract

The invention discloses a comprehensive intelligent protection system applied to power distribution automation. The system comprises a mounting unit, a power transmission and distribution gas unit anda DTU intelligent terminal; the mounting unit comprises a fixing plate, a bearing piece and a supporting piece, one end of the bearing piece is hinged to the fixing plate, the other end of the bearing piece can rotate relatively, and the two ends of the supporting piece are detachably connected to the fixing plate and the bearing piece respectively and can form a triangular stable structure; thepower transmission and distribution gas unit comprises a switching station box body and a ring main unit arranged in the switching station box body, and the fixing plate is attached and fixed to the outer side wall of the switching station box body; and the DTU intelligent terminal is placed on the bearing piece and is electrically connected with the ring main unit in the switching box body. According to the invention, the DTU intelligent terminal is installed on the power transmission and distribution gas unit in an externally-hung assembly mode, installation is not limited by the site, and the installation process is flexible and rapid.

Description

technical field [0001] The invention relates to the technical field of distribution automation, in particular to a comprehensive intelligent protection system applied to distribution automation. Background technique [0002] According to the distribution of the load, the existing ring network cabinets have different installation positions; according to the operation period, the types of ring network cabinets also have great differences. Some ring network cabinet switches themselves have electric operation mechanism and CT, and do not need to be modified It can be directly automated, but often due to insufficient space around the ring network cabinet, it is impossible to directly expand the foundation and install outdoor vertical DTU terminals next to the ring network cabinet, resulting in some ring network cabinets that cannot be automated due to the limitation of the surrounding space. The existing transformation process is generally to install DTU terminals on the new expa...
