Wiring-free centralized control type distribution automation terminal and system thereof

Abstract

The invention provides a wiring-free centralized control type distribution automation terminal and a system thereof. The terminal comprises a terminal central processing unit and a plurality of powerdistribution terminal subunits, wherein the terminal central processing unit is composed of a first power supply module, a first anti-surge protection module, a first EMC filtering module, a first central processing unit, a first Ethernet module and a WIFI module, the plurality of power distribution terminal subunits are used for collecting electrical signals of power distribution equipment, and the terminal central processing unit communicates with the plurality of power distribution terminal subunits through the WIFI module. The system provided by the invention comprises the power distribution automation terminal. The terminal is simple in structure, reasonable in design, free of wiring, and capable of rapidly positioning faults and being replaced in an electrified mode, and can guarantee the power supply continuity and reliability of a power distribution network so as to meet the requirements of an intelligent power grid.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a wiring-free centralized control type power distribution automation terminal and a system applied to the terminal. Background technique [0002] With the rapid development of the economy, the demand for electric power is increasing, and the requirements for the quality of electric energy and the reliability of power supply are also getting higher and higher. Distribution automation terminal is a new type of automatic power equipment integrating computer technology, information and communication, data transmission, control technology, modern equipment and management. Its purpose is to improve power supply reliability, improve power quality, provide users with quality services, and reduce Operating costs, reducing the labor intensity of operation and maintenance personnel, widely used in substations, switch stations, distribution stations, ring main units and other place...

AI Technical Summary

Problems solved by technology

The difference is that the 16-circuit power distribution automation terminal needs 2 power distribution automation core units 100, and the current and voltage terminals, wires, guide rails, wire slots and accessory materials also need to be doubled, and the number of wiring will also be doubled, but in The process of installation and production is similar. First of all, the corresponding wires must be prepared, the terminals should be pressed and the wire numbers should be threaded; secondly, the current and voltage terminals, guide rails, wire slots and other accessories need to be installed in the cabinet; finally According to the technical requirements of the drawings, the wires prepared in advance will be connected to the corresponding current and voltage terminals in the cabinet, because the data information collected by the 8-circuit power distribution automation terminal is the remote signal corresponding to 8 switches, Telemetry and remote control data, so every PCB circuit board on the distribution automation core unit must be connected to wires, plus the wiring of some external modules, such a distribution automation terminal needs to connect thousands of wires , and the 16-circuit power distribution automation terminal collects more data information, which is twice that of the 8-circuit power distribution automation terminal, and the number of connections is also twice that of the 8-circuit power di
