Definitions

  • the present invention relates generally to a set of electrical equipment.
  • the invention relates more particularly to a set of modular electric switchgear, this set including at least one alternating current circuit breaker.
  • the object of the present invention is to improve the structure of a modular DC circuit breaker.
  • a set of modular electric switchgear assemblies including alternating current circuit breakers, in which all the electric switchgear have a similar external shape in order to be able to be mounted side by side, the assembly comprising at least an accessory consisting of a housing having an external shape similar to that of the others electrical equipment of the assembly and containing a magnetic field generation means, the magnetic field propagating outside the housing at at least one side wall of the housing and substantially perpendicular thereto, so that, when an alternating current circuit breaker and said accessory are mounted side by side, the magnetic field supplied by the accessory crosses an arc extinguishing chamber of the alternating current circuit breaker in order to be able to operate this circuit breaker in direct current.
  • Element 1 is a conventional alternating current circuit breaker and element 2 is an accessory which is particular to the present invention and the function of which will be described later.
  • the alternating current circuit breaker 1 is a conventional circuit breaker which can be used in general in a low voltage electrical installation. In fact, in an installation electrical, it is common practice to have side by side a large number of various electrical devices and among these, there are mostly AC electrical circuit breakers such as that shown in Figure 1. If one wishes use the alternating current circuit breaker 1 as a direct current circuit breaker, we know that it is necessary to create, in the zone of formation of the electric arc, a transverse magnetic field.
  • Element 2 is an accessory according to the invention which makes it possible to use the alternating current circuit breaker 1 as a direct current circuit breaker by the simple fact of attaching the specific accessory 2 to the alternating current circuit breaker 1.
  • the accessory 2 is , according to the invention, consisting of a housing of a non-magnetic material, for example plastic.
  • the housing 3 has a general external shape which can be similar to the general external shape of the circuit breaker 1. However, its width need not be the same as that of the circuit breaker 1 and, preferably, its width may be more low. In fact, the only shape constraints of the housing 3 are those which make it possible to mount and fix the accessory 2 on a support for electrical equipment (not shown).
  • the housing 3 comprises two substantially flat and relatively thin side walls 4, 5. In FIG. 1, the side wall 5 which is situated on the right is therefore applied against a left side wall 6 of the circuit breaker 1.
  • a magnetic field generation means 7 is fixedly disposed inside the housing 3, interposed with minimum clearance between the side walls 4 and 5.
  • This magnetic field generation means 7 can be constituted either by a magnet permanent either of a magnetic coil.
  • this magnetic field generation means is a magnet 7, and in the following text we will say “magnet” to mean “magnetic field generation means", for the sake of brevity.
  • this means 7 is a magnetic coil, the latter is supplied electrically from the outside by means of electrical terminals (not shown) arranged at the rear of the accessory 2 so as to be able to continuously supply the coil magnetic when accessory 2 is mounted on a fixed support of an electrical installation (not shown).
  • the side walls 4 and 5 of the housing 3 of the accessory 2 also include protrusions directed inwards 8 which make it possible to retain and position the magnet 7 inside the housing 3.
  • the magnet 7 produces a magnetic field B which propagates outside the housing 3 in a manner substantially perpendicular to the side wall 5 of the housing 3, that is to say perpendicular to the wall lateral 6 of the circuit breaker 1.
  • the zone of maximum intensity of this magnetic field B when it crosses the circuit breaker 1 is preferably located in the region of arc formation in the circuit breaker mechanism of the circuit breaker 1.
  • FIG. 3 a simplified representation is shown, in front view, of a possible assembly using a set of electrical apparatuses according to the invention, this assembly comprising two alternating current circuit breakers 1A, 1B arranged side by side, a first accessory 2A placed on the left and against the circuit breaker 1A on the left and a second identical accessory 2B placed on the right and against the circuit breaker on the right 1B.
  • the accessory 2 according to the invention can be associated with an alternating current circuit breaker 1 by being disposed against it either to its right or to its left.
  • the magnet 7 is disposed in the housing 3 of the accessory 2 to provide a significant external magnetic field at a single side of the accessory 2.
  • the circuit breaker having to be associated with the accessory 2 in order to be able to operate in direct current would be disposed against the accessory, only on this same side in order to be effectively crossed by the magnetic field.
  • the width of the electrical equipment can be for example 18 mm and, in this case, the accessory 2 which is intended to be associated with these electrical equipment can have a thickness of 9 mm or 18 mm.
  • the side walls 4 and 5 of the housing 3 of the accessory 2 are preferably relatively thin, for example with a thickness of less than 2 mm, so that the magnet 7 is located at the smallest possible distance of the active area of the electrical equipment located next to and against the accessory 2. It is relatively easy to produce such relatively thin side walls 4 and 5 because these side walls, as well as the entire housing 3, can be made of plastic and because these side walls are not generally not subject to significant mechanical stress.
  • two magnetic field generation means may be provided at the two opposite lateral faces of the accessory, the magnetic orientations of these two magnetic field generation means being substantially the same in order to add up their effects.
