Embodiment Construction

[0030] exist figure 1 The figure shows a perspective view of an on-load tap-changer 1 according to the invention, which is arranged directly below a transformer housing 2 of a tapped transformer, not shown in greater detail. A more detailed description of the components of on-load tap-changer 1 and their function can be obtained from the following description of the drawings. Such tapped transformers, which are well known from the prior art, comprise a transformer housing filled with insulating oil, in which at least one winding is arranged on an iron yoke. The winding is composed of a main winding and an adjusting winding, and a plurality of winding sub-joints are arranged on the adjusting winding, and these winding sub-joints form an adjusting area. Furthermore, the on-load tap changer 1 has a drive module 3 fastened on the underside of the transformer housing 2 , which interacts with a motor drive 4 arranged on the opposite outer side of the transformer housing 2 . In thi...

Abstract

The present invention relates to an on-load tap changer for uninterrupted switching between different winding taps of a tapped transformer according to the first claim. The general inventive concept is that of arranging the on-load tap changer on the underside of the transformer cover by means of a gear module.

Description

technical field [0001] The invention relates to an on-load tap changer according to the preamble of claim 1 for switching without interruption between different winding taps of a tapped transformer. Background technique [0002] On-load tap-changers have been used worldwide for many years to switch between different winding taps of tapped transformers without interruption. So-called reactor switches, which are prevalent in North America in particular, have a switching impedance which enables slow continuous switching. Generally, an on-load tap-changer according to the resistance fast switching principle comprises: a selector for the power-free call-up (Anwahl) tap changer of the corresponding winding tap to which it should be switched; The tap is actually switched to the load changer on the new preselected winding tap. In addition, load switchers typically have switching contacts and resistive contacts. In this case, the switching contacts are used for the direct connecti...
