Abstract

System for autonomously reclosing a circuit breaker, characterised in that it comprises: a capacitor C as a single energy source, an adjustable time-delayed relay 2 preventing unintentional immediate reclosing, an electromagnet 4 which converts the electrical energy into a mechanical force, and, the current having been cut off, the reclosing takes place by virtue of the discharge of a capacitor C which requires no external supply at this given moment.

Description

DESCRIPTION
SELF-CONTINUED RE-ENCLOSURE SYSTEM FOR A CIRCUIT BREAKER
FOR DOMESTIC OR INDUSTRIAL USE
The invention relates to the following field
Electrical installations in domestic and industrial.

Previously, there was no maintenance-free stand-alone system
can reset a circuit breaker.

The system is based on the energy return of a capacitor (C)
direct current, which allows the reclosing of a circuit breaker (D).

The originality of the choice of the capacitor is based on the fact that it does not
requires no maintenance and only resets the number of times
calculated. This system supplies energy to an electromagnet (4) or
to the control coil (4) of an electric trigger circuit breaker (D).

The invention responds to the supply of energy by a component (the con
densifier) without any other device, whereas currently there is no
system like this, any device to date needing energy
rescue. Example: battery.

On the other hand, the capacitor (C) stores only a certain quantity
of energy determined by its value, it offers security in principle
dahs his job, namely that the capacitor cannot provide more energy
than the one he stored.

To make a copy of the invention, proceed as follows
Take an electrically operated circuit breaker (D); when it is closed (energized), it supplies a rectifier bridge (I) which supplies direct current to. a capacitor (C) and thus charges it.

When a break occurs caused by the circuit breaker, the system, after a time delay established by a time relay (2), returns its energy thanks to the DC capacitor) which discharges me on the coil (4) for controlling the circuit breaker ( D) electric trigger. The relay is made up of two parts, the first being used to nestle the condener (at the time of the
cut to prevent it from discharging, the second, timed, putting the capacitor () in. lei
coil supply circuit (4) after a given time,
example: 30 "
A second embodiment could be as follows: on the same.

In principle, the capacitor, instead of discharging on the coil of an electrically operated circuit breaker, could supply its energy to an electromagnet acting mechanically on the manually operated circuit breaker (domestic use).

This device can be switched off using a switch (3).

Anyone with an electrical installation, whether domestic or industrial, will find great advantages in using this system.

In fact, it allows individuals to avoid the inconveniences of a late re-engagement. Example: freezers, alarm systems, energy savings, and for manufacturers with operational requirements, to reduce their downtime as well as monitoring.

The device is adaptable to any meter power in single-phase or three-phase, alternating and direct current.
