Embodiment Construction

[0036] figure 1 An overview view of a possible embodiment of the device according to the invention is shown. The device according to the invention comprises at least two parts: a first part 1, intended to detect and locate faults on one or more electrical lines 3; and a second part 2, composed of at least one operable control switch or contactor 5. This switch can be electromechanical or electronic, for example based on transistors or thyristors. This switch is connected at the input to the power supply 4 and at the output to the electrical network 3 . Instead, the switch can be connected to a power supply at the output. This makes it obvious to consider the case of battery powered systems, where either the battery powers the motor or the motor powers the battery (which is then charging).

[0037] The first part of the device consists of at least one fault detection system 1 operating according to the reflex principle.

[0038] This principle is similar to that of radar. ...

Abstract

The invention relates to a device comprising at least one first portion (1) for detecting an electrical defect arising in a power grid, and a second portion (2) comprising at least one switch (5) connecting said power grid to a power supply source (4), the first portion (1) comprising at least one reflectometric detection system capable of being coupled with the power grid. Said system detects and analyzes impedance changes arising in the power grid, a signal being sent by said system to turn on the switch (5) when a detected impedance change is considered by said system to be an electrical defect.

Description

technical field [0001] The subject of the invention is a device for protecting an electrical network. This equipment is suitable for the protection of all types of electrical networks, regardless of their nature, whether they are intended for power supply or data transmission. Background technique [0002] The protection of any type of electrical installation is necessary for the safety of people and property. In fact, electrical failures frequently cause fires, often with catastrophic consequences. Electrical faults can also cause electrification of sensitive areas or, more significantly, electrocution of persons. [0003] Electrical protection is suitable for all types of electrical installations. This can notably include, for example, the electrical protection of buildings, industrial sites, aircraft and automobiles. This can also notably include the protection of new electrical production infrastructures such as wind farms or photovoltaic panel arrays. Other infrast...
