Description
Technical field
The utility model belongs to transformer coil lead technology field, is related to a kind of dry-type transformer high-voltage connection.
Background technology
Transformer lead is the important part of dry-type transformer, by with the wire connection terminal on high-tension coil, use
The mode of point-to-point is independently connected, and since lead is more, causes the fairlead quantity increase for being set with lead so that terminals
The weight increase born, simultaneously as connecting line is more, causes that the connection between lead and terminal is unstable, and contact surface not enough fills
Point, easily loosen, security risk is brought to transformer station high-voltage side bus.In order to ensure between high-voltage connection, high-voltage connection and coil and point
The insulation of connecting terminal has enough safe distances, it is necessary to sets enough transformer lead spaces, reduces connecting line and connecting rod
Weight, it is also necessary to mitigate the load-bearing burden of high-voltage connection terminal, improve the functional reliability of transformer.
The content of the invention
The object of the present invention is to provide a kind of dry-type transformer high-voltage connection connection structure, solves in the prior art, to exist
Because connecting line causes the connection between lead and terminal unstable more, the operation of the transformer is caused security incident easily occur
Problem.
The technical solution of the utility model is：A kind of dry-type transformer high-voltage connection, three groups of coils point of dry-type transformer
It is not coil I, coil II, coil III, the middle part of coil I is provided with high-voltage connection point A, top is provided with first branch lead point
X1, lower part is provided with the second branch lead point X2, the middle part of coil II is provided with high-voltage connection point B）, top is provided with first
Pass line point Y1, lower part is provided with the second branch lead point Y2, the middle part of coil III is provided with high-voltage connection point C, top is provided with
First branch lead point Z1, lower part is provided with the second branch lead point Z2, be horizontally disposed with folder has high-voltage connection on the transformer
Point I, high-voltage connection point II and high-voltage connection point III, high-voltage connection point I are connected by conducting wire with high-voltage connection point A, high-voltage connection
Point II is even connected by conducting wire with high-voltage connection point B, and high-voltage connection point III is connected by conducting wire with high-voltage connection point C；
First branch lead point X1With the second branch lead point X2It is connected by the first Y types connecting rod with high-voltage connection point B；
First branch lead point Y1With the second branch lead point Y2It is connected by the 2nd Y types connecting rod with high-voltage connection point C；
First branch lead point Z1With the second branch lead point Z2Led to by the 3rd Y types connecting rod and high-voltage connection point A
Connect；
First Y types connecting rod, the 2nd Y types connecting rod and the 3rd Y types connecting rod are equipped with insulation distance each other,
Two component wiring leading-out terminals are also set up on the coil I, coil II, coil III.
Using the technical solution of the utility model：High-voltage connection point is set in thiol, then is drawn high pressure with connecting rod
Line point is connected with corresponding branch lead point, realizes that multiple branch circuit is combined into a branch connection, in permitted relatively small sky
In to lead rational deployment, so as to reduce number of leads, it is ensured that contact abundant between lead and terminal, be connected firmly；In addition,
Since each connecting rod is into Y shape, triangular support is formed after connection, the weight that leading-out terminal is born is reduced, so as to increase
The security of strong transformer station high-voltage side bus.
