Abstract

The invention discloses a digital primary and secondary fusion ring main unit integrated system. The system comprises a ring main unit, and a power distribution station terminal cabinet, a voltage transformer cabinet and a plurality of switch cabinets which are arranged in the ring main unit; a digital power distribution station terminal, a power supply module and a communication box are configured in the power distribution station terminal cabinet; the digital power distribution station terminal is in communication connection with the main station through the communication box; a voltage transformer and a sensor digital unit are arranged in the voltage transformer cabinet; a switch unit, a current transformer, a sensor unit and a sensor digital unit are arranged in the switch cabinet; the sensor digitization unit is used for converting an analog signal of a sensor in the cabinet body into a digital signal and uploading the signal to the digital power distribution station terminal through communication connection; and the power supply module is electrically connected with the digital power distribution station terminal, the sensor digital unit and the switch unit. Wiring can be simplified, cost is saved, and the digitization level of the ring main unit complete system is improved.

Description

technical field [0001] The invention relates to a digital primary-secondary fusion ring cage complete system, which belongs to the technical field of power distribution stations. Background technique [0002] The ring net box is a kind of electrical equipment that installs high-voltage equipment in a metal or non-metal insulated cabinet and makes it into an assembled interval ring network power supply unit. Its core components are voltage transformers, current transformers and circuit breakers or load switches. [0003] The distribution station terminal (DTU) is the power distribution terminal equipment installed at the ring network box. It completes the data collection and calculation of the position signal, voltage, current, power, line loss and other data of the switchgear, and completes the analysis of the switchgear. Closing operation, identification of feeder switch faults, etc. [0004] The existing complete set of primary and secondary fusion ring cage technology i...
