Description
Technical field
The utility model relates to transformer technology fields, and in particular to a kind of transformer coil supporting block.
Background technique
The basic principle of transformer be the ratio between former and deputy coil induced electromotive force be equal to turn ratio, it is ensured that the number of turns it is accurate,
It is necessary that insulation, insulation breakdown just will form turn-to-turn short circuit between circle and circle between circle and circle, the number of turns variation leads to transformation
Device cisco unity malfunction；Due to the structural relation of transformer, a winding has plurality of layers, if turn-to-turn short circuit makes the number of turns
Small variation, then layer short circuit just makes the number of turns that big variation have occurred, so layer insulation is just more important, transformer around
Group insulate between being divided into former pair, the insulation between different windings to be just called winding, and supporting block usually in transformer interlayer or
It is used in insulation between winding, the coil of transformer is made to keep certain interval between layers, traditional supporting block is usually
The contact surface of quadrangle, ellipse, supporting block and coil is small, and insulation performance is poor, and be easy to cause damage coil, to transformer
Operation causes certain risk hidden danger.Therefore, design that a kind of structure is simple, prevents coil impaired and the transformation of good insulation preformance
Device coil supporting block is of great significance.
Utility model content
Purpose of the utility model is to solve above-mentioned technical problem, provide a kind of structure is simple, prevent coil it is impaired,
The transformer coil supporting block of good insulation preformance.
In a first aspect, providing a kind of transformer coil supporting block, including the first support plate, the second support plate, and connection
What the shape of the connecting plate of the first support plate and the second support plate, first support plate and the second support plate was contacted with it
Coil shape is adapted, and is provided with the first groove in first support plate, and the second groove, institute are provided in the second support plate
State connecting plate include match with the first groove connection the first insert plate, with the second groove match connection second insertion
Plate, and the connecting rod of connection the first insert plate and the second insert plate, first insert plate, the second insert plate, connecting rod are whole
Body is in I-shaped.
With reference to first aspect, in the first possible implementation of the first aspect, first support plate and second
Fillet is respectively arranged on four angles of support plate.
With reference to first aspect, in the second possible implementation of the first aspect, first support plate and second
Several circular holes are evenly distributed in support plate.
The utility model has the beneficial effects that:
The utility model is by setting I-shaped the first insert plate, the second insert plate, connecting rod, and for connecting plate
One insert plate be embedded in the first groove in, the second insert plate be embedded in the second groove in, increase the supporting surface of coil, prevent coil by
Damage, improves the insulation performance of transformer coil；By will be set as round on four angles of the first support plate and the second support plate
Angle further reduced the risk of damage coil, improve its dielectric level；By equal in the first support plate and the second support plate
It is even to be provided with several circular holes, enhance the heat-sinking capability of coil.
Detailed description of the invention
