Column switch anti-error remote control locking system and operation method

Abstract

The invention discloses a column switch anti-error remote control locking system and an operation method. The locking system includes a distribution network anti-error system and a column switch device and is characterized in that the distribution network anti-error system is electrically connected with a handheld intelligent operation terminal, the handheld intelligent operation terminal is electrically connected with a remote controller, the remote controller is electrically connected with a feed line intelligent terminal, and the feed line intelligent terminal is electrically connected with the column switch device. When in operation, the problems that when a column switch device is operated, only a simple prompt type locking measure is provided but no imperative locking measure is provided, the operation is easy to be influenced by operators' mood and experiences, and work conditions, and misoperation or wrong operation sequences may be caused by carelessness, and major accidents such as large-area shutdown, loop closing, and loop opening can be caused, and the safe and stable operation of the whole power distribution network is influenced are solved by the operation procedures of operation order generation, operation order downloading, on-site position confirmation, real-time anti-error verification, remote operation, equipment state confirmation etc.

Description

technical field

[0001] The invention belongs to the technical field of power system safety, and in particular relates to a pole-mounted switch anti-misoperation remote control locking system and an operation method. Background technique

[0002] The wiring mode of overhead lines in distribution network has developed from the initial radiation-type non-contact to "hand-in-hand" single-connection to today's multi-segment and multi-connection "ring network power supply open-loop operation" mode. The traditional distribution production, operation, Management methods often cannot meet the needs of the new situation, and distribution network security accidents occur from time to time. When the distribution automation technology is still immature, the distribution operation and maintenance department generally uses local remote control to operate the switchgear on the pole. During operation, there is only a simple reminder lock, and there is no mandatory lock measure, which is easy...
