Description
Technical field
The invention belongs to field of electric power automation, is related to a kind of realize and the long-range distribution monitor of interval function is set automatically
It is standby.
Background technology
The normal operation of power system be unable to do without monitoring in real time, and distribution system is also such.It is at full speed with network technology
Development, distributing monitoring system develop into high in the clouds mode by original mode on the spot, realize the long-range of distributing monitoring system,
A variety of applications can be realized on the basis of this, the long-range operation maintenance of such as distribution system, big data are shared, Energy Efficiency Analysis.Remotely match somebody with somebody
The dependable with function of electricity consumption monitoring system depends on the reliability of distributing monitoring system data, the i.e. data in high in the clouds and scene
Whether real time data is consistent.How to ensure the uniformity of both, generally use be scene manually to the mode of data, that is, match somebody with somebody
Electric scene is compared with back-end data by the manually addend evidence in distribution monitor equipment, so time consuming, and is needed
Field Force possesses higher quality.And distribution system can be divided into the distribution interval of difference in functionality, such as inlet wire interval, outlet
Interval, capacitor standoff etc..Data per class interval are essentially identical, unique the difference is that compartment name.
The content of the invention
The technical problems to be solved by the invention are to make up drawbacks described above, there is provided a kind of to realize automatically to the remote of interval function
Journey distribution monitor equipment.
The technical problem of the present invention is solved by the following technical programs.
This realization is automatically to the long-range distribution monitor equipment of interval function, by host CPU module, AC current-voltage input
Module, memory module, RS485 communication interface modules, power module, indicator lamp and automatically to interval module form.
