Intelligent support suitable for circuit breaker or drop-out fuse

Abstract

The invention discloses an intelligent support suitable for a circuit breaker or a drop-out fuse. The support comprises a support frame, and one side of the support frame is provided with a wire inlet and wire outlet end combined sensor. One end of the wire inlet end combined sensor is provided with an upper contact holding mechanism, and a wire inlet terminal is arranged above the upper contact holding mechanism; a lower contact is mounted at one end of the wire outlet end combined sensor; a mounting frame, an information acquisition unit and an information processing unit are mounted on the other side of the support frame; and the wire inlet and wire outlet end combined sensor is connected with the information acquisition unit. The problem that a conventional fuse support does not have the functions of remote signaling, remote measurement and online monitoring is effectively solved, and the functions of real-time monitoring of the operation state of the drop-out fuse, fault type discrimination, automatic positioning of fault points, line loss monitoring and the like are realized.

Description

technical field [0001] The invention belongs to the field of outdoor high-voltage power distribution equipment, and in particular relates to an intelligent bracket suitable for circuit breakers or drop-out fuses. Background technique [0002] The traditional drop-out fuse brackets are simple mechanical switches, which only provide the rotation of the lower contact, mechanical retention, and maintenance of the rated pressure of the upper contact for the drop-out fuse, and satisfy certain parameters of thermal stability and other electrical properties. They do not have intelligence. Sensors and control functions cannot realize remote control, line status collection, automatic reclosing after faults, power quality monitoring, line loss monitoring, fault location and other automatic functions. After a fault, the operation and maintenance personnel can only rely on the power outage area to find the power outage point. , which is not conducive to quickly troubleshooting and restor...

[0002] The traditional drop-out fuse brackets are simple mechanical switches, which only provide the rotation of the lower contact, mechanical retention, and maintenance of the rated pressure of the upper contact for the drop-out fuse, and satisfy certain parameters of thermal stability and other electrical properties. They do not have intelligence. Sensors and control functions cannot realize remote control, line state collection, automatic reclosing after faults, power quality monitoring, line loss monitoring, fault location and other automatic functions. After a fault, the operation and maintenance personnel can only rely on the power outage area to find the power outage point. , which is not conducive to quick troubleshooting and restoration of power supply, and cannot meet the needs of the existing distribution network automation process
