Abstract

The present invention relates to an instrument transformer (1) for high current and / or high voltage conversion, comprising a housing and at least an active part, which is electrically insulated by an isolation material. The isolation material comprises particles (14). A method for the instrument transformer (1) comprises the filling of a housing of the instrument transformer (1) with particles (14), particularly with particles (14) of paper material and / or cellulose, which were impregnated by an insulating fluid (10), particularly mineral oil and / or a synthetic oil, and / or ester, particularly vegetable esters.

Description

technical field [0001] The invention relates to a transformer and method for high current and / or high voltage switching, comprising a housing and at least one active part electrically insulated by an insulating material. Background technique [0002] An oil-insulated transformer or measuring transformer is known, for example, from US 5 391 835A. Transformers are used for measuring large currents and / or voltages, especially in the range up to several hundred amperes and / or up to 1200 kV. The transformer includes a housing and at least one active part including a measurement assembly. The measuring assembly comprises, for example, a winding arranged around an electrical conductor, which can be used to measure the current in the conductor by means of magnetic induction in the winding. The active part is electrically insulated from the housing of the transformer by the insulating material. The entire measurement assembly or parts of the measurement assembly are wrapped in kra...
