High-voltage device having a measuring resistor
First Claim
Patent Images
1. A high-voltage device comprising:
- a plurality of capacitors and at least one internal resistor for the measurement of high voltage;
wherein the plurality of capacitors are aligned so as to form at least two parallel planes, where terminals corresponding to a first set of the plurality of capacitors define a first plane, and terminals corresponding to a second set of the plurality of capacitors define a second plane;
wherein the measuring resistor comprises terminals defining a third plane, the third plane disposed between and parallel to the at least two parallel planes; and
wherein the first set of capacitors are electrically connected in series with each other, the second set of capacitors are electrically connected in series with each other, and the first set of capacitors are electrically connected in parallel with the second set of capacitors so as to create an electrical field surrounding the measuring resistor, the terminals of the measuring resistor being disposed proximate the terminals of the parallel arrangement of capacitors such that the electrical field has a voltage potential across the parallel arrangement of capacitors similar in value to a voltage potential across the measuring resistor that is generated during steady state operation of the measuring resistor, thereby shielding the measuring resistor from a ground potential.

Abstract
A high-voltage device having a measuring resistor, also called a bleeder, is plunged into an electrical field whose voltage varies in the same way as the voltage along the bleeder. To achieve this, the capacitive elements are distributed in two rows, each row defining a plane. Along each row, the potentials are growing. The space between the two rows is sufficient for the bleeder to be placed therein. The bleeder is formed either by series-connected resistors or by a screen-printed resistor.
