Embodiment Construction

[0052] figure 1 A conventional anodizing unit 1 from the prior art and as described above in the context of the prior art is shown. Nevertheless, it should be noted that the figure 1 In the example shown in , although plant 40 is an aluminum anodizing plant comprising a plurality of aluminum electrolytic cells, the invention is not limited to this application, but more generally relates to a magnetically saturated reactor comprising Short-circuit test method for transformers.

[0053] In particular, this anodizing unit 1 includes, inter alia, a transformer 20 , known as a rectifying transformer, installed at the interface between the device 40 and the power circuit 30 . For each phase of the power circuit 30, the rectifier transformer 20 includes:

[0054] the primary winding 210 connected to the corresponding phase of the power circuit;

[0055] • A secondary winding 220 with a positive leg and a negative leg; and

[0056] A set of two magnetically saturated reactors 230...

Abstract

The invention relates to a method of testing a transformer (20), known as a rectifier transformer, designed to be installed at the interface between a device and a power circuit having at least one phase, the rectifier transformer (20) For each phase of the power circuit comprising a primary winding and a secondary winding, the secondary winding (220) is intended to be connected to the device (40) via the rectifier circuit (30) via a positive branch and a negative branch, each branch being equipped with a magnetically saturated reactor (230a, b, c, d, e, f), the method comprising the steps of short-circuiting each positive branch and the corresponding negative branch, and measuring the impedance and / or loss. The invention also relates to an electrical testing system (2), a short circuit (50) and an anodizing unit.

Description

technical field [0001] The present invention relates to a transformer for use in high power rectification circuits, particularly for supplying direct current (DC) to devices such as devices comprising aluminum electrolytic cells. Background technique [0002] refer to figure 1 A transformer 20 for a rectification circuit (hereinafter referred to as a "rectification transformer") is generally designed to be installed at an interface between a power supply circuit 10 having at least one phase and a device 40 such as a device including an aluminum electrolytic cell. figure 1 Such a rectifying transformer 20 installed at the interface between the power supply circuit 10 having three phases and the electrolyzer device 40 is shown. [0003] Such a rectifying transformer 20 comprises, for each phase, two windings: a primary winding 210 and a secondary winding 220, said windings 210, 220 being adapted to be connected in a delta or star configuration, such as figure 1 shown. Each ...
