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 distribution automation terminal. The installation and production of the 16-loop power distribution automation terminal connected by two wires puts forward higher requirements for the production personnel, and the probability of wrong wiring will also greatly increase

[0006] In addition, the traditional power distribution automation terminal must be debugged or after the operation and maintenance personnel arrive at the site, the parameters can be configured by connecting the power distribution automation terminal with a laptop computer with a network cable. Every time a parameter is modified, the operation and maintenance personnel must go to the site to operate it again , which greatly increases the labor intensity of the operation and maintenance personnel, and also increases the maintenance cost; the traditional distribution automation terminal needs to connect a large number of secondary lines to realize the collection of various signals. Once a failure occurs, it will cost a lot of It takes a long time to find the fault point, and the power outage time will become very long, and the economic loss will be greater; when the technical requirements of the distribution automation master station change, the traditional distribution automation terminal cannot be remotely modified online or To upgrade the system, debugging or operation and maintenance personnel must go to the site to modify and upgrade the database
