Description
Technical field
The utility model is related to the winding structure between a kind of transformer outlet and bus, belongs to transformer manufacturing equipment skill
Art field.
Background technology
Power transformer is NETWORK STRUCTURE PRESERVING POWER SYSTEM complexity, the most one of electric equipment of core the most.With voltage class
And the raising of power transformation capacity, itself vibration and the earthquake of transformer turn into the key factor of the normal operation of influence transformer, domestic
It is outer to have carried out substantial amounts of transformer vibration monitoring and Controlling research.
Due to itself vibration or earthquake of transformer, can pull the connection cable between transformer outlet and bus
Phenomenon, causes bushing shell for transformer to suffer destruction problem, influences the normal operation of transformer.Therefore, the antidetonation energy of transformer is improved
Power is to improve the important step of power system quake-resistant safety.The pulling of connection cable is to bushing shell for transformer between transformer and bus
Destruction is a key issue urgently to be resolved hurrily.
Utility model content
The utility model purpose is to provide the winding structure between a kind of transformer outlet and bus, when transformer itself
When vibration and earthquake, it is ensured that the connection cable between transformer and bus can be capable of expansion and contraction, solve present in background technology
Problem.
The technical solution of the utility model is：
Winding structure between a kind of transformer outlet and bus, comprising metal tube axle, scroll spring, outboard tube axle, pipe
Shaft housing and connection cable, outboard tube axle are located in pipe shaft housing, the external diameter of the internal diameter more than metal tube axle of outboard tube axle, metal
Pipe axle is located in outboard tube axle, and the two 1 of metal tube axle is fixed on pipe shaft housing, metal tube axle and the concentric cloth of outboard tube axle
Put, metal tube axle is respectively arranged at two ends with scroll spring with outboard tube axle, and one end of the scroll spring is fixed on metal tube axle
Outside, the other end of scroll spring is fixed on the inwall of outboard tube axle, and connection cable is penetrated and twined from one end of metal tube axle
It is wound on outboard tube axle.
The outboard tube axle is provided with the perforation being engaged with connection cable.
Internal diameter of the external diameter of the connection cable less than metal tube axle.
The outboard tube axle and pipe shaft housing are made of glass fibre.
Using the utility model, when pulling near transformer side connection cable end, the outside under the drive of scroll spring
Pipe axle is rotated, and connection cable is unclamped；After external force disappears, scroll spring resets, and outboard tube axle rotates back to original state, connection electricity
Cable withdraws.
The beneficial effects of the utility model are：When transformer itself vibrates or earthquake occurs, between transformer and bus
Connection cable can be capable of expansion and contraction, prevent because of the pulling of the connection cable between transformer outlet and bus and caused by sleeve pipe
Destruction, it is ensured that the normal operation of transformer.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
In figure：Metal tube axle 1, scroll spring 2, outboard tube axle 3, pipe shaft housing 4, connection cable 5.
Specific embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 1, the winding structure between a kind of transformer outlet and bus, comprising metal tube axle 1, scroll spring 2,
Outboard tube axle 3, pipe shaft housing 4 and connection cable 5, outboard tube axle 3 are located in pipe shaft housing 4, and the internal diameter of outboard tube axle 3 is more than gold
The external diameter of category pipe axle 1, metal tube axle 1 is located in outboard tube axle 3, and one end of metal tube axle 1 is fixed on pipe shaft housing 4, metal
Pipe axle 1 and the concentric arrangement of outboard tube axle 3, metal tube axle 1 are respectively arranged at two ends with scroll spring 2, the scrollwork with outboard tube axle 3
One end of spring 2 is fixed on the outside of metal tube axle 1, and the other end of scroll spring 2 is fixed on the inwall of outboard tube axle 3, even
Cable 5 is connect to penetrate and be wrapped on outboard tube axle 3 from one end of metal tube axle 1.
In the present embodiment, outboard tube axle 3 and pipe shaft housing 4 are made of glass fibre, the pipe that glass fibre is made
The outer side spray of shaft housing 4 has the paint of anti-corrosion, windproof, leakproof and antiultraviolet.Connection cable 5 is between transformer outlet and bus
Connection cable, its external diameter less than metal tube axle 1 internal diameter.Metal tube axle 1 is two sections, is respectively provided at the two ends of outboard tube axle 3,
And concentric arrangement, pipe shaft housing 4 is provided with the perforation being engaged with connection cable 5.
When due to transformer itself vibrate or occur the external force that the reason such as earthquake produces pull transformer outlet and bus it
Between connection cable 5 in the case of, scroll spring 2 drives outboard tube axle 3 to rotate, and connection cable 5 is unclamped；After external force disappears,
Scroll spring 2 automatically resets, and outboard tube axle 3 rotates back to original state, and connection cable withdraws.Make the telescopic of connection cable 5
Freely, it is unlikely to damage other parts being connected with connection cable, it is ensured that the normal operation of transformer.
