HIGH-VOLTAGE COLUMN CURRENT TRANSFORMER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240047134 titled 'HIGH-VOLTAGE COLUMN CURRENT TRANSFORMER

Simplified Explanation

The abstract describes a high-voltage column current transformer that includes a column insulating body and a head. The head has a volume and contains a primary winding conductor, a secondary winding core assembly with secondary winding leads, and a conical insulator spacer. The conical insulator spacer is tapered from a base to an apex and is positioned with its base on the bottom of the head facing the column insulating body. The apex of the spacer holds the secondary winding core assembly away from the wall of the head. The spacer also includes at least one ring-shaped electrode embedded in and surrounding the base, and another flat, circular-shaped electrode embedded in and surrounded by the apex. Additionally, the spacer has at least one opening in the lateral face.

  • The high-voltage column current transformer includes a column insulating body and a head.
  • The head contains a primary winding conductor, a secondary winding core assembly, and a conical insulator spacer.
  • The conical insulator spacer is tapered from a base to an apex and is positioned with its base on the bottom of the head.
  • The apex of the spacer holds the secondary winding core assembly away from the wall of the head.
  • The spacer includes at least one ring-shaped electrode surrounding the base and another flat, circular-shaped electrode surrounded by the apex.
  • The spacer also has at least one opening in the lateral face.

Potential Applications:

  • High-voltage power transmission systems
  • Electrical substations
  • Power generation plants

Problems Solved:

  • Insulation and spacing of high-voltage components
  • Protection against electrical arcing and breakdown
  • Efficient current measurement and transformation

Benefits:

  • Improved insulation and spacing for high-voltage applications
  • Enhanced protection against electrical faults and breakdowns
  • Accurate and efficient current measurement and transformation


Original Abstract Submitted

a high-voltage column current transformer comprising a column insulating body and a head arranged thereon is disclosed, whereby the head defines a volume and comprises arranged therein a primary winding conductor, a secondary winding core assembly having secondary winding leads and a conical insulator spacer tapered from a base to an apex with a lateral face therebetween, the conical insulator spacer is arranged with its base on a bottom of the head facing the column insulating body and its apex holds the secondary winding core assembly distant from a wall of the head, the conical insulator spacer comprises at least one ring-shaped electrode embedded in and surrounding the base and another flat, circular shaped electrode embedded in and surrounded by the apex, and the conical insulator spacer comprises at least one opening in the lateral face.
