Abstract

The utility model discloses a transformer, in particular to a unilateral line feeding structure of transformer, which comprises a transformer housing, a lead wire elbow, a cable terminal socket and a low voltage sleeve; wherein, the cable terminal socket is connected with the lead wire elbow arranged on the lateral face of the transformer; the section of the lead wire elbow is L bent shape; the plug and play direction of the cable terminal socket is arranged a certain included angle with ground; the transformer is 35 to 220KV transformer. The utility model has the advantages of matching with high-voltage cable plug, facilitating underground cabling of high-voltage cable, lowering the total height of transformer, reducing phase distance, construction convenience and low equipment cost.

Description

A kind of one-sided inlet wire structure of transformer

(1) technical field

The utility model relates to a kind of transformer, is specially a kind of one-sided inlet wire structure of transformer.

(2) background technology

Present stage, 35～220kV level transformer high-voltage inlet wire adopts sleeve pipe usually, is arranged in the transformer tank side of covering, and the transformer overall height dimension increases, and alternate size is bigger, adopts buried cable inlet wire inconvenience; Also have at present and adopt the cable termination socket to substitute the transformer that bushing is transformed, the cable termination socket arrangements on the bushing installing hole of the transformer tank side of covering, the cable distribution complexity; Some new design is at present directly adopted the cable termination socket in the side of transformer, and the plug direction is vertical with the transformer tank wall, and cable needs bending after underground drawing and before plug-in cable termination socket is connected, and it is big to take up room.

(3) summary of the invention

The utility model provides the one-sided inlet wire structure of a kind of inlet wire convenience, the little transformer that takes up room in order to remedy the deficiencies in the prior art.

The technical solution of the utility model is:

A kind of one-sided inlet wire structure of transformer, comprise transformer-cabinet, lead-in wire bend pipe, cable termination socket, low-tension bushing, its special character is: the cable termination socket links with the lead-in wire bend pipe that is arranged in the side of transformer, lead-in wire bend pipe cross section is the L bending, and the plug direction and the ground of cable termination socket are in a certain angle.

The one-sided inlet wire structure of transformer of the present utility model, described transformer are 35～220kV level transformer.

The utility model is the transformer inlet wire structure that has the cable termination socket, its cable termination socket links with the lead-in wire bend pipe that is arranged in the side of transformer, the lead-in wire bend pipe slightly is the L bending, the plug direction and the ground of cable termination socket are in a certain angle, be used with high potential cable termination, be convenient to realize the high-tension cable underground distribution, effectively reduce the transformer overall height, reduce phase spacing; It is the comparatively compact one-sided inlet wire structure of utility model transformer of a kind of volume.

That the utility model takes up room is little, easy construction, effectively reduce the transformer overall height, reduce equipment manufacturing cost.

(4) description of drawings

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

Fig. 1 looks schematic diagram for master of the present utility model;

Fig. 2 is a schematic top plan view of the present utility model;

Fig. 3 looks schematic diagram for a left side of the present utility model.

Among the figure: 1 is transformer-cabinet, and 2 are the lead-in wire bend pipe, and 3 is low-tension bushing, and 4 is the cable termination socket.

(5) embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model.The one-sided inlet wire structure of the transformer of this embodiment, comprise transformer-cabinet 1, lead-in wire bend pipe 2, cable termination socket 4, low-tension bushing 3, cable termination socket 4 links with the lead-in wire bend pipe 2 that is arranged in the side of transformer, lead-in wire bend pipe 2 slightly is the L bending, and the plug direction and the ground of cable termination socket 4 are in a certain angle, after the high pressure underground cable is drawn from ground, can directly dock with cable termination socket 4, need not bending, it is little to take up room, easy construction; Transformer low voltage sleeve pipe 3 is arranged in transformer-cabinet 1 top, is convenient to overhead outlet.The transformer high-voltage inlet wire adopts cable termination socket 4, is arranged in the side of transformer, is convenient to realize the high-tension cable underground distribution, reduces the phase insulation distance, effectively reduces the transformer overall height, reduces equipment manufacturing cost.

Claims (3)

1. the one-sided inlet wire structure of a transformer, comprise transformer-cabinet (1), lead-in wire bend pipe (2), cable termination socket (4), low-tension bushing (3), it is characterized by: cable termination socket (4) links with the lead-in wire bend pipe (2) that is arranged in the side of transformer, lead-in wire bend pipe (2) cross section is the L bending, and the plug direction and the ground of cable termination socket (4) are in a certain angle.
