Description

Electricity consumption scene cloud data beginning case

Technical field

The utility model relates to a kind of wiring cabinets, and in particular to a kind of data access unit concentration for electric substation connects Line case.

Background technique

Electricity supplying and using system is a complexity and strongly professional work, and the stable operation of route and equipment is to ensure user The basic guarantee of reliable electricity consumption.Mainly there is following 3 class operation and maintenance mode at present and respectively perplex as follows:

(1) the shortcomings that artificial on duty and manual mode of operation:

(1) electrical equipment malfunction occurs often and reacts not in time, and cause damages heaviness；

(2) operator on duty cannot prevent trouble before it happens to equipment or route, and bursting problem occurs, cannot debug in time； When breaking down, producing cause cannot be positioned promptly and accurately, not only be delayed emergency repair time, but also waste man power and money；

(3) high to the professional requirement of personnel due to that should not be saved for complete artificial on duty and operation, various records, it needs Personnel are more, and working efficiency is low.

(2) artificial combination local on duty electric power monitoring system or the shortcomings that background computer system mode:

(1) high construction cost: needing dedicated background monitoring room, and dedicated background computer and desk, sound equipment, printer are matched Electric cabinet, ups power etc.；

(2) maintenance cost is high: the operator on duty's moment for needing professional skill monitors background system, and alarm not in time, is System consumption electric energy itself is higher；

(3) background system fault point itself is more, should not check: background system hardware device degradation failure, software operation system System crashes, and application software is that usually there are inherent shortcomings for definite value；Measuring and controlling equipment is generally the connection of RS485 bus, a node Outlet problem influences whole total built-in unit, and it is difficult to check malfunctioning node.
