Title:
CURRENT BREAKING DEVICE FOR HIGH-DC-VOLTAGE ELECTRIC CURRENT, INSTALLATION COMPRISING SUCH A DEVICE, CONTROL METHOD AND PROCESS FOR EVALUATING THE INTEGRITY OF AN ELECTRICAL CONDUCTOR
Document Type and Number:
WIPO Patent Application WO/2022/029379
Kind Code:
A3
Abstract:
The invention relates to a breaking device (28) for a high-DC-voltage current including, in succession, an isolating switch (48), a first primary point (44.1) and a first breaking module (40.1), characterized in that the breaking device (28) includes, between the first primary point (44.1) and ground (52), a precharge circuit (50) that has a precharge capacitor (54, 54.1), a precharge resistor (56) and a precharge switch (58), and in that the breaking device has at least: - one charging configuration (C_CH) for allowing the precharge capacitor to be charged; and - one precharging configuration (C_PCH) for allowing the precharge capacitor (54, 54.1) to be discharged into a conductor (12). The invention also relates to a method for controlling such a device and a process for evaluating the integrity of an electrical conductor.
