Description

Technical Field

[0001] The utility model relates to the technical field of chopsticks, in particular to a transformer winding structure replacing a PT measurement function. Background Art

[0002] The existing transformer voltage monitoring adopts the method of passing the cable through the PT (voltage transformer). When the voltage is high, if the insulation is not properly handled, insulation breakdown is likely to occur, damaging the transformer and PT. Utility Model Content

[0003] The purpose of the utility model is to provide a transformer winding structure that replaces the PT measurement function, so as to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transformer winding structure that replaces the PT measurement function, comprising an iron core, a screw rod is horizontally provided at the center of the iron core, brackets are symmetrically provided on both sides of the iron core, a U-shaped copper shielding tube is connected between the two brackets, and windings are provided inside the copper shielding tube.

[0005] Preferably, screws are provided at both ends of the screw rod, and the bracket is connected to the screw rod via the screws.

[0006] Compared with the prior art, the utility model has the following beneficial effects: the utility model protects the windings through the copper shielding tube to avoid the risk of insulation breakdown, and after adopting this winding structure, the original PT measuring equipment can be eliminated, thereby reducing the cost of the entire system and improving the safety performance of the system.
