The invention discloses an intelligent distribution network controller, which mainly comprises: a communication interface for receiving data information from a control terminal and an uploading controller; a processor for parsing and processing the data information and issuing operation instructions; a relay The output module is used to use the signal source provided inside the controller to drive the motor of the handcart / ground knife to rotate according to the above-mentioned operation instructions, and after reaching the designated position, trigger a trigger signal; or drive the intermediate relay of the circuit breaker to pull in, Realize the closing / opening operation of the circuit breaker; the digital input module collects the above trigger signal and feeds it back to the processor, the processor cuts off the relay output, and controls the motor braking that drives the handcart / ground knife; the display module displays the circuit breaker , ground knife status and single-line diagram, and system control operation interface. The invention realizes one-key programmed electric operation for various operating states of the central cabinet, and effectively solves the problems of cumbersome manual operation, fault location, and difficulty in maintenance and repair of the traditional switch cabinet. The invention also discloses an intelligent distribution network control method.
Description
technical field [0001] The invention relates to a 10KV / 35KV central cabinet distribution network controller, in particular to an intelligent distribution network programmed controller, which is used for remote control, monitoring, Measurement, fault location and motor protection. Background technique [0002] At present, most of the distribution network of the central cabinet adopts the traditional solution: the closing and opening of the circuit breaker can be operated locally, or remotely operated by the remote control center; On-site manual operation using a crank handle; the grounding switch closing and opening operation is also manually completed by the operator on site; when a fault occurs on site, it is impossible to quickly and effectively locate the fault, which makes on-site maintenance difficult and increases the workload of the operator. Increase the accident rate of on-site maintenance. Contents of the invention [0003] The purpose of the present invention ...
