Description

A kind of Multifunctional power distribution automatization terminal

Technical field

The utility model relates to the switchyard, switchgear house, ring main unit, the distribution power automation terminal in box-type substation that are arranged on distribution feeder loop.

Background technology

In power distribution network, load is complicated and changeable, Connection Mode varies in different localities of a great variety, and due to the characteristic of distribution, electrical network is often in three-phase imbalance state, and the power distribution network auxiliary facility of China is incomplete, the problems such as it is many that this series of factors causes distribution network failure, and accident is many, and interruption duration is long, power supply reliability is low, the quality of power supply is poor.Along with socioeconomic development, the ability that user bears power failure is more and more weak, has had higher requirement to power supply quality, reliability.Distribution power automation terminal can significantly improve power distribution network reliability of operation, improves the quality of power supply, reduces work about electric power person's labour intensity, and can make full use of the ability of existing equipment.

summary of the invention

The purpose of this utility model is just to provide a kind of every state parameter to being arranged on primary equipment in 10kV and above power distribution network and carries out Real-Time Monitoring, the Multifunctional power distribution automatization terminal controlled, for realizing above object, technical solution adopted in the utility model is: comprise power module, output module, intake acquisition module, communication module, CPU module and analogue collection module, be interconnected by bus board between each module, and all external interfaces are all opened to the outside world by the mode of general pluggable plate, power module provides power supply for other module, DC quantity collecting part in power module, intake acquisition module, the signal collected is sent to CPU module by analogue collection module, monitoring result is uploaded to background computer by communication module by CPU module, CPU module drives and outputs module deciliter circuit breaker simultaneously.

This terminal is installed in the component cabinet such as switchyard, ring main unit, and termination function module can be joined flexibly, can according to the actual demand of engineering site apolegamy open into, output, the number of the module such as analog acquisition.It is high that this terminal has certainty of measurement, and system safety is stablized, the feature such as flexible and convenient to use, the mode that the distribution power automation terminal required for national grid one of providing is new.

Accompanying drawing explanation

Fig. 1 is structured flowchart of the present utility model;

Fig. 2 is external structure schematic diagram of the present utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As depicted in figs. 1 and 2, the utility model comprises power module 1, outputs module 2, intake acquisition module 3, communication module 4, CPU module 5 and analogue collection module 6, be interconnected by bus board between each module, and all external interfaces are all opened to the outside world by the mode of general pluggable plate.Power module 1 provides power supply for other module, the signal collected is sent to CPU module 5 by the DC quantity collecting part in power module 1, intake acquisition module 3, analogue collection module 6, and monitoring result is uploaded to background computer by communication module 4 by CPU module 5.

During terminal operating, intake signal, circuit voltage signal enter terminal by intake acquisition module 3 and analogue collection module 6; This mode can not affect primary equipment internal electrical structure, so both ensure that the integrality of sensor signal, turn avoid terminal and primary equipment and to be directly connected the electrical Interference caused.When terminal monitors the faults such as primary equipment generation overcurrent, overvoltage by analogue collection module 6, terminal CPU module 5 can drive outputs module 2 deciliters circuit breakers, after deciliter success, circuit breaker can be conjugated information and be sent to CPU module 5 by intake acquisition module 3, simultaneously, the data that each acquisition module sends by CPU module 5 carry out arranging, analyze and after a series of high level computer algorithm process, judge corresponding fault type, reach master station computer with serial ports or Ethernet interface after then judged result being changed by communication module 4 in form.
