Description

A distribution network fault location system based on section switch and FTU

technical field

The utility model relates to a distribution network fault location system based on a section switch and an FTU.

Background technique

The distribution network includes a busbar and multiple outgoing lines drawn from the busbar, and each outgoing line is divided into multiple sections. When a fault occurs in the outgoing line of the distribution network, there is currently no good method to quickly and accurately locate the fault location.

At present, when locating the fault point of the outgoing line, it is relying on electric power workers to scan the line section by section to find the fault point, which requires a lot of manpower, material resources and time, and seriously reduces the reliability of power supply.

Contents of the invention

The purpose of this utility model is to provide a distribution network fault location system based on section switches and FTUs in order to solve the above problems.

The purpose of this utility model is achieved in that:

A distribution network fault location system based on segmented switches and FTUs of the utility model, the distribution network includes a busbar and several outgoing lines drawn from the busbar, and the distribution network fault location system includes several segmented switches, Several FTUs and master stations, among them,

The section switches are distributed and installed on each outgoing line;

The FTU is installed at each section switch and communicated with the section switch;

The master station is respectively connected to each FTU in communication.

In the above distribution network fault location system based on section switches and FTUs, the main station is connected to each FTU through wired or wireless communication.

In the above-mentioned distribution network fault location system based on section switches and FTUs, the master station is respectively connected to each FTU by wired communication through optical fibers.

In the above-mentioned distribution network fault location system based on section switches and FTUs, the main station is connected to each FTU through GPRS for wireless communication.

While the FTU is measuring the running data of the outgoing line, it can judge the running status of the outgoing line in real time. If the outgoing line fails, the master station will judge the fault point through the data uploaded by the FTU, and then control the segmental switches on both sides of the fault point to disconnect through the FTU. , Isolate faults and ensure sound section power supply.

The utility model can accurately and reliably locate faults and quickly isolate faults, greatly saves manpower, material resources and time consumption, and provides reliability and stability of power supply.

Fig. 1 is the structural representation of the utility model.

Detailed ways

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

Please refer to Figure 1, the distribution network includes bus 1 and several outgoing lines drawn from bus 1 (1#, 2#...N#, N≥2 and is a positive integer);

The utility model distribution network fault location system includes several section switches 201, several FTU202 and the main station 3, wherein, the section switches 201 are distributed and installed on each outgoing line (1#, 2#...N#), and the FTU202 Installed at each section switch 201 and communicated with the section switch 201 there; the master station 3 is respectively connected with each FTU202 by wired or wireless communication, the wired communication connection is preferably optical fiber, and the wireless communication connection is preferably GRPS.

FTU202 measures the running data of the outgoing line (1#, 2#...N#), and at the same time judges the running status of the outgoing line in real time. If the outgoing line fails, the master station 3 judges the fault point through the data uploaded by FTU202. Then, the section switch 201 on both sides of the fault point is controlled to be disconnected by the FTU202, so as to isolate the fault and ensure a sound section power supply.

The above embodiments are only for illustrating the utility model, rather than limiting the utility model. Those skilled in the art can also make various transformations or modifications without departing from the spirit and scope of the utility model. Therefore, all equivalent technical solutions should also belong to the category of the present utility model, and should be defined by each claim.
