Abstract
The utility model relates to a high-voltage lead clamping structure of a transformer. The high-voltage lead clamping structure comprises a transformer iron core clamping part and is characterized in that a pair of wooden supports are vertically arranged on the transformer iron core clamping part, the top ends of the two wooden supports are connected through a support crosspiece, and the support crosspiece is provided with a clamping crosspiece which is matched with the support crosspiece and used for clamping a high-voltage lead. The high-voltage lead clamping structure disclosed by the utility model has the advantages of shortening the straight-line distance between the lead wire and the iron core clamping part, prolonging the creepage distance between the lead wire and an iron core web and reducing the local discharge risk.
Description
Technical field
The utility model relates to a kind of transformer high-voltage lead-in wire clamp structure, is applicable to 110kV level and above transformer.
Background technology
Transformer device structure is more and more compacter now, but must guarantee electric insulation intensity necessarily again.In order to improve high pressure 110kV level and above lead-in wire insulation level over the ground, need design more superior lead-in wire clamp structure.
Summary of the invention
The purpose of the utility model is to provide a kind of transformer high-voltage lead-in wire clamp structure, and this structure shortens the air line distance of lead-in wire to the iron core folder, prolongs the creepage distance of lead-in wire to the iron core web, has reduced the risk of partial discharge.
The utility model is characterised in that: a kind of transformer high-voltage lead-in wire clamp structure; Comprise the transformer core folder; It is characterized in that: erect on the said transformer core folder and be provided with a pair of brace; Two brace tops one are supported beam and are connected, and said support beam is provided with and is mated the clamping beam that is used for the clamping high-voltage connection.
Above-mentioned support beam top middle portion offers first half-arc groove, and said clamping beam center bottom offers second half-arc groove that is used with first half-arc groove.
The length of above-mentioned clamping beam is less than the length that supports beam.
The advantage of the utility model: simple in structure, easy to operate, safe and reliable; High-voltage connection is through supporting the support of beam; Strengthened the creepage distance of high-voltage connection to the iron core folder; Avoid the high-voltage connection bending, improved the operating efficiency of lead-in wire operation, avoided the damage in insulation that causes because of the lead-in wire bending; Support beam and adopt two end supports, avoided cantilever beam structure, prevented the shake of beam in the transformer running, help the long-term safety operation of transformer; Shorten the air line distance of lead-in wire, prolong the creepage distance of lead-in wire, thereby the size of having dwindled fuel tank can realize the effect that originally needs very big space just can reach in very limited space, reduced the risk of partial discharge the iron core web to the iron core folder.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Among the figure: 1 is the transformer core folder; 2 is brace; 3 for supporting beam; 4 is high-voltage connection; 5 are the clamping beam; 31 is first half-arc groove; 51 is second half-arc groove.
Embodiment
For letting the above-mentioned feature and advantage of the utility model can be more obviously understandable, hereinafter is special lifts embodiment, and cooperates appended graphic elaborating as follows.
With reference to legend; A kind of transformer high-voltage lead-in wire clamp structure; Comprise transformer core folder 1; It is characterized in that: perpendicular a pair of brace 2, the two braces 2 tops one support beam 3 that is provided with is connected on the said transformer core folder 1, and said support beam 3 is provided with and is mated the clamping beam 5 that is used for clamping high-voltage connection 4.
Above-mentioned support beam 3 top middle portion offer first half-arc groove 31, and said clamping beam 5 center bottom offer second half-arc groove 51 that is used with first half-arc groove 31.
The length of above-mentioned clamping beam 5 is less than the length that supports beam 3.
In the utility model one preferred embodiment, support beam and clamping beam and be connected through the screw realization of being located at clamping beam both sides, the specification of two braces is identical.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
