Description

High-voltage head end fixing plate groove pad structure of transformer

Technical Field

The utility model relates to a transformer high pressure head end fixed plate groove pad structure belongs to large-scale power transformer technical field.

Background

In the assembly of large-scale transformer, the first head of transformer high pressure is drawn forth and is needed to carry out the centre gripping with electrically conductive clamp, because the fixed plate that fixed wire pressed from both sides is the metalwork for the unsatisfied insulation distance requirement of the high-pressure head end of part transformer to the distance of fixed plate, prior art's solution is at fixed plate department winding crepe paper, this kind of mode exists difficult operation, the scheduling problem that drops easily, if cause to drop can lead to the high-pressure head end can not satisfy the creepage requirement and arouse discharging, there is the hidden danger to the safe operation of transformer.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a transformer high pressure head end fixed plate groove pad structure, convenient operation can not drop, satisfies the safety margin that the high pressure lead wire arrives the fixed plate, eliminates the potential safety hazard, solves the above-mentioned technical problem that prior art exists.

The technical scheme of the utility model is that:

a transformer high-voltage head end fixing plate groove pad structure comprises a transformer iron core, a clamping piece, a fixing plate, a groove pad, a wire clamp and a high-voltage lead, wherein the transformer iron core is clamped by the clamping piece, the wire clamp is fixed on the clamping piece by the fixing plate, the head of a transformer high-voltage coil is connected with the high-voltage lead by the wire clamp, the groove pad is arranged on the fixing plate, the groove pad is made into a U-shaped groove by a paper plate, the fixing plate is inserted into the U-shaped groove, the groove pad covers the right side surface, the upper surface and the lower surface of the fixing plate; the U-shaped groove is provided with a mounting hole and is fixedly connected with the wire clamp through a mounting bolt.

The U-shaped groove upper surface and the lower surface of groove pad respectively are equipped with two mounting holes, and the mounting hole corresponds each other from top to bottom, and the mounting bolt is insulating bolt, and the mounting bolt presss from both sides the wire with the fixed plate fastening together to carry on spacingly to the groove pad, thereby satisfy the safety margin of high-voltage lead wire to the fixed plate.

The utility model has the advantages that: the operation is convenient, the falling-off is avoided, the safety margin from the high-voltage lead to the fixing plate is met, and the potential safety hazard is eliminated.
