Abstract

The utility model relates to a cable network structure of a power distribution network, which comprises transformer stations, K type stations, P type stations and WX type stations. The transformer stations are connected with K type stations connected with P type stations or K type stations connected with P type stations and WX type stations to form a radiation type wiring structure. Compared with the prior art, the cable network structure of the power distribution network can increase the power consumption reliability, etc.

Description

A kind of cable system structure of power distribution network

Technical field

The utility model relates to a kind of distribution system, especially relates to a kind of cable system structure of power distribution network.

Background technology

The general wiring complexity of distribution system, number of devices is various, amount of information is huge, exist certain related between each device parameter and the state, corresponding data and operate closely relatedly, the forecast assessment of finishing distribution system user power supply reliability by craft is very difficult.Develop software systems for forecast assessment even can utilize computer technology, but if the software systems of exploitation only are off-lines, then the user still needs to utilize graphical interfaces manually to draw electric hookup in advance on computers, parameter and the state information of input all devices, and when electric network composition changes, power system operating mode or Plant maintenance plan change and when having new equipment to drop into, also need the user artificially to revise winding diagram and device parameter, workload is very big, simultaneously also make mistakes the situation that the result will cause the real work personnel that the off-line forecast assessment software systems of developing are given it up easily.

The network configuration of power distribution network is the basis of its reliability level, brief flexible net topology can ensure user's dwindling of scope that have a power failure, namely under failure condition, non-faulted line segment load is changeed band, arrange in advance non-pre-arrangement line segment load to be changeed band under the power-off condition at equipment.

Summary of the invention

The purpose of this utility model is exactly to provide a kind of cable system structure that improves the power distribution network of electricity consumption reliability for the defective that overcomes above-mentioned prior art existence.

The purpose of this utility model can be achieved through the following technical solutions: a kind of cable system structure of power distribution network, it is characterized in that, comprise transformer station, K type station, P type station and WX type station, described transformer station connects the radial pattern wiring construction at K band P type station, type station or band P type station, K type station and WX type station.

Band P type station, described K type station refers to that a K type station connects three P type stations.

Band P type station, described K type station refers to that with WX type station a K type station is connected two P type stations, connects the WX type station of four circulation series connection simultaneously.

Described transformer station is provided with a plurality of, and each transformer station connects two K type stations, each K type station connects three P type stations.

Described transformer station is provided with a plurality of, and each transformer station connects two K type stations, each K type station connects two P type stations and two WX type stations, and between two WX type stations two WX type stations of series connection.

Compared with prior art, the utility model distribution wiring pattern is reasonable, cable system adopts the radial pattern wiring pattern at band P type station, K type station or band WX type station, K type station substantially, can ensure user's dwindling of scope that have a power failure with brief flexible net topology, has improved the reliability of electricity consumption.

Description of drawings

Fig. 1 is the structural representation of utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Embodiment
