Amount.3rd, clear failure type, carries out repairing and prepares, and supporting module repairing work is carried out, and lifts first-aid repair efficiency.
Brief description of the drawings
Below in conjunction with the accompanying drawings and implementation method the present invention is further detailed explanation：
Fig. 1 is frame principle figure of the present invention；
Specific embodiment
The low-voltage distribution network fault location system that the present apparatus as shown in Figure 1 is provided, it is characterized in that, including information about power adopts
Collection module, switch changed position acquisition module and data concentrated collection module；Acquisition module is arranged on transformer side in data set；Electricity
Information acquisition module is arranged on feeder pillar side collection three-phase current, voltage；Switch is changed into acquisition module installed in user's electricity box side
The switch changed position information of total air switch in collection user's electricity box, and all points of switch changed position information of family air switch in user's electricity box；Electricity
Amount information acquisition module, the data of switch changed position acquisition module collect into data set acquisition module by power carrier.
Low-voltage distribution network fault location system is by acquisition module, feeder pillar side information about power collection mould in transformer side data set
Block and the part composition of user's electricity box side switch changed position acquisition module three.Feeder pillar side information about power acquisition module and user's electricity box side
The data of switch changed position acquisition module collection collect the acquisition module into transformer side data set by power carrier.
The effect of acquisition module is the electricity by each branch node in power carrier picking platform area in transformer side data set
Total air switch in parameter, and each electricity box, the switch changed position information of point family air switch.In addition in transformer side, concentrated collection module is also led to
Cross the electrical parameter of each outgoing line interval of serial acquisition.Data of the concentrated collection module also to being gathered are analyzed treatment, work as low pressure
During distribution outlet failure, point is occurred according to each node data analyzing and positioning failure, and analysis result is passed through into wired or wireless net
Network is real-time transmitted to management platform.
The effect of feeder pillar side information about power acquisition module is three-phase current, the voltage for gathering each branch in feeder pillar.
The power supply of information about power acquisition module, voltage sample and current sample take from the outgoing line side of branch switch.
The effect of user's electricity box side switch changed position acquisition module is the switch changed position information for gathering total air switch in electricity box, and table
The all points of switch changed position information of family air switch in case.Switch changed position acquisition module power supply takes from the end of incoming cables of the total air switch of electricity box, protects
Various switch changed position situations occur in card electricity box can accurately be detected.
When certain node outgoing failure in low-voltage distribution network, concentrated collection module can be automatically analyzed and event according to network topology
Other related node data information of barrier node, so that clear failure occurs position.Electric quantity acquisition module and switch changed position are gathered
Module is all corresponded in low-voltage distribution network fault location system all with information such as address, table numbers with actual track, equipment.
Failure being accurately positioned with reference to these information, point occurs.
Specifically：
It is each in acquisition module meeting active poll platform area in transformer side data set when low-voltage distribution network fault location system runs
The electric parameter of individual information about power acquisition module, switch changed position acquisition module and appearance interval.
Information about power acquisition module, switch changed position acquisition module also can automatically monitor respective gathered data, if it happens
The failure situation such as switch changed position, decompression, can be immediately by failure active reporting to acquisition module in data set, so as in time to failure
Analyze, position and report management platform.
When switch changed position acquisition module detects single or multiple points of family air switch displacements, and electricity box where these point of family air switch
Total air switch state it is normal, failure can be positioned directly in corresponding point family air switch.The fault message for reporting can carry this point
Family air switch correspond to actual floor number, unit number, floor number and number.
There is displacement in total air switch that switch changed position acquisition module detects certain electricity box, then it is the electricity box that can position failure
Total air switch.
If all electricity box switch changed position module communication disruptions of certain branch, according to other points in Network topology feeder pillar
The voltage data of branch, if other branch's voltage datas are normal, can fault point be the branch air switch.
If all branch datas are abnormal in same feeder pillar, acquisition module gathers outlet where the feeder pillar in data set
The voltage data at interval, if data are normal, trouble point is total air switch of the feeder pillar.If voltage data is abnormal, failure
The air switch of point outgoing line interval where the feeder pillar.
It is clear example of the present invention that above-mentioned case study on implementation is only, and is not the limit to embodiment of the present invention
It is fixed.To belonging to the obvious change or change still in protection scope of the present invention that spirit of the invention amplifies out.
