Definitions
- the invention relates to equipment for high voltage networks, in particular the supply of control or control circuits to be connected to a high voltage equipment.
- Equipment used in high voltage networks such as power lines, transformers or power converters, require local electronic circuits. These electronic circuits are used either to control electronic power components or to perform measurements and control operations on the equipment. The supply voltages of this electronic circuit are much lower than the potential difference between the ground and the high voltage level of the equipment to which the electronic circuit is contiguous.
- a supply of the electronic circuit from a source connected to the earth poses problems of galvanic isolation between the ground and the high voltage, all the more annoying that the voltage level is high. The sizing constraints of the circuit can then make its cost prohibitive.
- FR738101 discloses a high voltage electrical insulator. This insulator is designed to divert energy from a high-voltage conductor through the insulator. A primary winding passes through the insulator along its axis and connects its input to its output. The primary winding is surrounded by an insulating sleeve. A secondary winding surrounds the insulating sleeve.
- Fiber optic feeds have also been proposed. Such power supplies are based on a light emitted by the power supply to the earth, the transmission of this light by an optical fiber, and the conversion of this light into electricity by a converter attached to the electronic circuit. However, such power supplies are particularly expensive and provide only a very limited power.
- the invention aims to solve one or more of these disadvantages. There is thus a need for a simple and safe solution for supplying electronic circuits connected to high voltage, from a ground potential, without limitation of autonomy.
- the invention thus relates to a high voltage electrical insulator, as defined in appended claim 1.
- FIG 4 is a sectional view of a second variant of fixing a resonant circuit on an insulator body
- FIGS. 6 and 7 correspond to embodiments of resonant circuit windings embedded inside the material of the insulating body 11 and with a winding produced by tracks on a printed circuit.
