Summary of the invention
The purpose of this utility model provides a kind of distribution network failure navigation system based on block switch and FTU exactly in order to address the above problem.
The purpose of this utility model is achieved in that
A kind of distribution network failure navigation system based on block switch and FTU of the present utility model, described power distribution network comprises bus and some outlet circuits of drawing from bus, described distribution network failure navigation system comprises some block switches, some FTU and main website, wherein
Described block switch distributes and is installed on each outlet circuit;
Described FTU is installed on each block switch place, and is connected with this block switch communication;
Described main website is connected with each FTU communication respectively.
Above-mentioned a kind of distribution network failure navigation system based on block switch and FTU, wherein, described main website is connected by wired or wireless communication with each FTU respectively.
Above-mentioned a kind of distribution network failure navigation system based on block switch and FTU, wherein, described main website carries out wire communication with each FTU by optical fiber respectively and is connected.
Above-mentioned a kind of distribution network failure navigation system based on block switch and FTU, wherein, described main website carries out wireless telecommunications with each FTU by GPRS respectively and is connected.
FTU is when measuring outlet circuit service data, and the running status of real time discriminating outlet circuit is during as if the outlet line failure, the data failure judgement point that main website uploads by FTU, block switch by FTU control both sides, fault point disconnects again, and isolated fault guarantees to perfect the section power supply.
The utility model is the earth fault location accurately and reliably, and can carry out Fault Isolation fast, and the consumption of having saved human and material resources and time greatly provides the reliability and stability of powering.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See also Fig. 1, power distribution network comprises bus 1 and some outlet circuits of drawing from bus 1 (1#, 2#...N#, N 〉=2 and be positive integer);
The utility model distribution network failure navigation system comprises some block switches 201, some FTU202 and main website 3, wherein, block switch 201 distributes and is installed on each outlet circuit (1#, 2#...N#) on, FTU202 is installed on each block switch 201 place, and is connected with block switch 201 communications at this place; Main website 3 is connected with the wired or wireless communication of each FTU202 respectively, and wire communication connects preferred fiber, and wireless telecommunications connect preferred GRPS.
FTU202 is measuring outlet circuit (1#, 2#...N#) service data the time, the running status of this outlet circuit of real time discriminating, if during the outlet line failure, the data failure judgement point that main website 3 uploads by FTU202, block switch 201 by FTU202 control both sides, fault point disconnects again, and isolated fault guarantees to perfect the section power supply.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
