Abstract
The utility model relates to a 35kV side line transformer assembly. The 35kV side line transformer assembly comprises three transformer devices and input lines, output lines and connection lines all connected on the transformer devices. Each input line is a power transmission line. The input lines are respectively connected to the transformer devices through 35kV inlet wires. The output lines which are three power transmission lines are used for transmitting power to client sides needing 35kV power. The connection lines are connected with 35kV transformer stations. Compared with the prior art, the 35kV side line transformer assembly has the advantages of wiring simplicity, balanced currents, low network loss, low investment, running convenience and convenient maintenance, etc.
Description
Technical field
The utility model relates to a kind of transformer group, especially relates to a kind of 35kV side line road transformer device.
Background technology
35kV transformer station is generally with the different bus radiation of power supply wiring, and indivedual transformer stations are different electrical power radiation wiring.In this mode of connection, transformer station's separate unit main transformer power supply can only obtain the power supply that does not have other to get in touch with on the circuit from a paths.This high voltage distribution network wiring is simple, the trend equilibrium, and network loss is low, invests for a short time simultaneously, and operation maintenance is convenient.Its shortcoming is that the busy line corridor is more, and wiring is comparatively complicated, is unfavorable for during fault that load shifts.
The utility model content
The purpose of this utility model is exactly to provide a kind of wiring simple for the defective that overcomes above-mentioned prior art existence, the 35kV side line road transformer device of trend equilibrium.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of 35kV side line road transformer device, comprise three device for transformer and be connected incoming line, outlet line and connection line on the device for transformer, described incoming line is a transmission line, be connected to device for transformer through the 35kV inlet wire, described outlet line is three transmission lines, be transported to need 35kV user side, described connection line connects 35kV transformer station.
Described device for transformer is the transformer of 20MVA.
Described device for transformer is the transformer of 31.5MVA.
Described outlet line adopt single busbar connection four segmentations or the six segmentation modes of connection to be transported to need 35kV user side.
It is 240-400mm that described incoming line, outlet line and connection line adopt the cross section
2Single to piece together cable, Two bors d's oeuveres cable or cross section be 630mm
2Single cable of piecing together.
Compared with prior art, it is simple to the utlity model has wiring, the trend equilibrium, network loss is low, invest simultaneously little, advantage such as operation maintenance is convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 is that device for transformer, 2 is that incoming line, 3 is that outlet line, 4 is connection line.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of 35kV side line road transformer device, its structure as shown in Figure 1, employing one is advanced three and is gone out the belt switch station character mode of connection, comprise three device for transformer 1 and be connected incoming line 2, outlet line 3 and connection line 4 on the device for transformer, the device for transformer 1 that uses is the transformer of 20MVA or the transformer of 31.5MVA.It is 240-400mm that incoming line 2, outlet line 3 and connection line 4 can adopt the cross section
2Single to piece together cable, Two bors d's oeuveres cable or cross section be 630mm
2Single cable of piecing together.Incoming line 2 is a transmission line, is connected to device for transformer 1 through the 35kV inlet wire, and outlet line 3 is three transmission lines, adopt single busbar connection four segmentations or the six segmentation modes of connection to be transported to need 35kV user side.Connection line 4 connects 35kV transformer station.
