Domain.
Background technology
With the continuous development of DC transmission engineering, DC converter transformer is as current conversion station main equipment demand also not
Disconnected increase, valve side lead is one of part of most critical in converter power transformer, because its design, technique, manufacturing flow are suitable
Complexity, qualified supply of material producer is few, and process-cycle very long etc. factor has had a strong impact on that the change of current becomes fabrication cycle, and then influences China
The development in an all-round way of DC transmission engineering.In addition, the existing horizontal outlet structure in valve side lead valve side is complicated, converter power transformer is caused to exist
Need to be individually designed to every product during design, the inconvenience of inadequate supply and design is also caused to a certain extent.Therefore, to change
Enter converter power transformer design structure, the situation of graduated release valve side lead inadequate supply, accelerate the development of direct current electric transmission and transformation industry, make
New type of valve side outlet structure is very urgent.
The content of the invention
It is rational in infrastructure, be easily achieved it is an object of the present invention to provide a kind of converter power transformer new type of valve side outlet structure, effectively
Graduated release valve side lead inadequate supply situation, be advantageous to the fast development of direct current electric transmission and transformation industry, solve on existing for background technology
State problem.
The technical scheme is that：
Converter power transformer new type of valve side outlet structure, it is exhausted using aluminum pipe in the wire outlet part of converter transformer valve-side lead
Edge, multilayer insulation paper web and corrugated board structure are used in outlet, is gradually transitions wrinkle paper structure；
Multilayer insulation paper web and corrugated board be set outside the aluminum pipe of outlet, every layer of insulating paper cylinder ladder from inside to outside
Overlap joint arrangement, the length of primary insulation paper web are more than the length of outer layer insulation paper web, and proportional spacing is taken between multilayer insulation paper web
Connect；Corrugated board is set between adjacent two layers insulating paper cylinder, and the length of corrugated board is more than upper strata insulating paper cylinder, exhausted less than lower floor
Edge paper web；The lap-joint of insulating paper cylinder sets flat paperboard, and the insulating paper cylinder and corrugated board thickness outside aluminum pipe are gradually thinning, transition
To wrinkle paper structure, the aluminum pipe outsourcing crimped paper away from outlet, wrinkle paper bag insulate to flat paperboard, continues bag insulation, to most
At outer layer insulation paper web, six layers of crimped paper of flat paperboard outer wrapping, wrinkle paper structure is completed.
The wrinkle paper bag insulate to flat paperboard, extracts flat paperboard out 50mm, continues bag insulation, to outermost layer insulating paper cylinder
Place, the unilateral 8mm of outsourcing insulation, wrapping length is 200mm.
The outlet aluminum pipe, provided with voltage equalizing ball and square ring.
Every layer of corrugated board docks around aluminum pipe, butt seam≤2mm.Corrugated board is if necessary to splice, in joint
With 1mm T4 paper plate bondings, and bag crimped paper 5-6 layers.The present invention is hardened using multilayer insulation paper web and corrugated paper in outlet
Structure, corrugated board play a supportive role between multilayer insulation paper web, and play certain insulating effect.
The positive effect of the present invention：It is rational in infrastructure, be easily achieved, effective graduated release valve side lead inadequate supply situation, favorably
In the fast development of direct current electric transmission and transformation industry.

Embodiment
Below in conjunction with the accompanying drawings, by embodiment, the present invention will be further described.
Converter power transformer new type of valve side outlet structure, it is exhausted using aluminum pipe 4 in the wire outlet part of converter transformer valve-side lead
Edge, multilayer insulation paper web 3 and the structure of corrugated board 6 are used in outlet, is gradually transitions the structure of crimped paper 1；
Multilayer insulation paper web and corrugated board be set outside the aluminum pipe of outlet, every layer of insulating paper cylinder ladder from inside to outside
Overlap joint arrangement, the length of primary insulation paper web are more than the length of outer layer insulation paper web, and proportional spacing is taken between multilayer insulation paper web
Connect；Corrugated board is set between adjacent two layers insulating paper cylinder, and the length of corrugated board is more than upper strata insulating paper cylinder, exhausted less than lower floor
Edge paper web；The lap-joint of insulating paper cylinder sets flat paperboard 2, and the insulating paper cylinder and corrugated board thickness outside aluminum pipe are gradually thinning, mistake
Crossing to the structure of crimped paper 1, the aluminum pipe outsourcing crimped paper 1 away from outlet, wrinkle paper bag insulate to flat paperboard 2, continues bag insulation,
To outermost layer insulating paper cylinder, flat paperboard 2 outer wrapping, six layers of crimped paper, the structure of crimped paper 1 is completed.
The wrinkle paper bag insulate to flat paperboard 2, extracts flat paperboard 2 out 50mm, continues bag insulation, to outermost layer insulating paper
