Definitions

  • the present invention relates to a low-voltage power circuit breaker having improved functions and characteristics; more specifically, the expression "low-voltage power circuit breaker” is used to reference a circuit breaker for applications with operating voltages below 1000 Volt.
  • Said power circuit breakers which typically operate with AC currents whose nominal operating values, according to the applications, can vary over a wide range, typically from a few hundred to several thousand amperes, are devised to provide some performances which are required in order to ensure the correct operation of the electric power supply circuit that they protect and of the loads connected thereto.
  • they protect the loads from abnormal events caused for example by malfunctions related to short circuits or due to overloads by automatically opening said power supply circuit; they allow the correct insertion/exclusion of loads in/from the electric power supply circuit; they ensure that the nominal current for the various connected users is actually equal to the required one, and allow, by manual intervention on an operating lever of said circuit breaker and by corresponding separation of the moving contacts from the fixed contacts, the complete isolation of a load with respect to a power supply source and the consequent disconnection of the circuit that they protect.
  • the actuation devices used are generally constituted by actuation systems of the mechanical type which use appropriate spring-loaded kinematic systems.
  • Such a system according to the preamble of claim 1 is known for example from EP-A-0867903.
  • the association of said actuation devices with the two interruption methods used, despite allowing adequate execution of the functions required of the circuit breaker, in any case entails some drawbacks and disadvantages.
  • circuit breakers with air-insulated interruption and mechanical actuation have a mechanical life which can vary from a few thousand to a maximum of a few tens of thousands of switching operations, and a significantly lower electrical life, mainly due to the formation of intense electric arcs which significantly deteriorate the contacts.
  • the electrical life increases considerably and reaches in practice the same order of magnitude as the mechanical life.
  • it is necessary to program and correctly perform a complex maintenance plan during the use of the circuit breaker, so as to compensate for variations caused by wear and aging which are typical of mechanical systems.
  • a maintenance plan forces the removal of the circuit breaker from active service, the use of labour and the consequent expenditure of time and cost, and becomes particularly onerous in all applications in which it is essential to provide protection against unexpected interruptions, such as for example in process industries.
  • actuation devices with spring-loaded kinematic systems are inherently very complicated and bulky; the level of mechanical energy that they must develop is proportional to the various levels of electrical performance of the circuit breaker in which they are used, for example breaking capacity for short circuits, nominal current, et cetera, and requires long and complicated testing and calibration operations.
  • the aim of the present invention is to provide a low-voltage power circuit breaker which has a longer useful life than known types of circuit breaker and at the same time allows to fully eliminate, or at least significantly reduce, the maintenance interventions required to ensure said useful life.
  • an object of the present invention is to provide a low-voltage power circuit breaker whose useful life is considerably longer than in the circuit breakers of the known art and in particular in which the mechanical and electrical life are maximized and have substantially the same value.
  • Another object of the present invention is to provide a low-voltage power circuit breaker whose constructive architecture is considerably less complicated than known types of circuit breaker.
  • Another object of the present invention is to provide a low-voltage power circuit breaker which is highly reliable, relatively easy to manufacture and at competitive costs.
  • a low-voltage power circuit breaker comprising a vacuum chamber which contains at least one fixed contact and at least one moving contact which can be mutually coupled/uncoupled in correspondence of a closed/open condition of the circuit breaker, and actuation means which are operatively connected to the moving contact and provide the energy required to move said moving contact and to determine its coupling/uncoupling with respect to said fixed contact, characterized in that said actuation means comprise an electromagnetic actuator.
  • the low-voltage power circuit breaker comprises an enclosure 1 which is in vacuum and contains at least one fixed contact 7 and at least one moving contact 6.
  • the vacuum enclosure 1, which constitutes the interruption chamber of the circuit breaker can be constituted by an appropriately shaped bulb inside which vacuum is maintained; the embodiment of the bulb and the manner in which the vacuum is maintained inside it are widely known in the art and are accordingly not described further.
  • the fixed contact 7 is electrically connected, by using conventional conducting means 4, for example a copper bar, to a user to be supplied, not shown; in turn, the moving contact 6 is electrically connected, by virtue of conducting means 5, to a power supply line, also not shown in the figure.
  • Said conducting means 5 can be constituted by a plurality of flexible metal strips which are packed together and perforated at their opposite ends, so as to accommodate means for connection to the moving contact 6 and to the power supply line.
  • the metal strips are arranged so as to form a substantially U-shaped turn; in this manner, when a short-circuit condition occurs, the two arms of the U-shaped turn are affected by two forces which are orientated in mutually opposite directions and so as to contrast the repulsion forces that are generated during the short circuit and tend to separate the contacts.
  • the strips allow to keep the contacts closed for a short initial interval of the short circuit, during which, for example, another circuit breaker possibly included in the power supply network can intervene, thus avoiding untimely interventions and the deactivation of users which could instead continue to operate correctly. Once this interval has elapsed, if no other circuit breaker (if present) has intervened, the contacts separate.
  • the movements for opening/closing the circuit breaker 100 are performed by moving the moving contact 6 so as to produce its engagement/disengagement with respect to the corresponding fixed contact 7; the energy required to perform these switching operations is supplied by appropriate actuation means which are operatively connected to the moving contact 6 by virtue of a kinematic chain which is generally designated by the reference numeral 3 in Figure 1.
  • a single pole of the circuit breaker 100 is shown for the sake of simplicity in description.
  • the actuation means comprise an electromagnetic actuator 2; the use of an actuator of this type allows to considerably extend the useful life of the circuit breaker, since it does not have the problems of possible wear and/or damage that are typical of mechanical-type actuators, allowing in particular to make the electrical useful life of the circuit breaker practically equal to its mechanical life. Furthermore, the electromagnetic actuator ensures the correct execution of the opening/closure movements of the circuit breaker without requiring any maintenance interventions during its useful life, or at least for a significantly large number of switching operations.
  • the electromagnetic actuator 2 is a permanent-magnet electromagnetic actuator.
  • the permanent-magnet actuator 2 comprises a magnetic yoke 10, an armature 30 which can move within the space formed by the yoke 10, and a pivot 20 which is fixed to the armature 30 and is suitable to transmit the motion to the kinematic chain 3 and therefore ultimately to the moving contact 6.
  • the movable armature 30 can be shaped in various manners according to the applications and/or specific requirements and can be provided monolithically and be made of ferromagnetic material or by means of a plurality of stacked magnetic sheets.
  • the yoke 10 is constituted by two core parts, designated by the reference numerals 40 and 50 respectively, which have an E-shaped profile and are mounted on a suitable support, not shown, so that two air gaps, designated by the reference numerals 18 and 19 respectively, form between them.
  • Two permanent magnets designated by the reference numerals 26 and 27 respectively, are mounted on the facing surfaces of the two intermediate arms 13 and 23 of the cores 40 and 50; furthermore, two excitation coils 44 and 45 are arranged in the spaces formed between the central arm 13 and 23 and the two end arms, designated by the reference numerals 41 and 22 respectively, of the cores 40 and 50.
  • a power supply unit schematically designated in Figure 1 by the reference numeral 8, which preferably comprises, according to a solution which is simple, not cumbersome and effective, one or more capacitors which are dimensioned appropriately and are supplied by the electric mains or by an auxiliary source of electric power.
  • the power supply unit 8 is operatively controlled by an electronic command unit 9, which is also connected to the power supply mains; said electronic command unit 9, according to an intervention command which originates for example from a protection system or from an operator, causes the intervention of the power supply unit 8; in this manner the capacitors discharge and energize the coil.
  • the kinematic chain 3 comprises two linkages 35 and 36 which transmit the motion from the pivot 20 to a transmission lever 37; said transmission lever 37, by turning about its pivoting point 38, produces the movement of a coupling pivot 39 which is rigidly coupled thereto and is connected to the moving contact 6; in this manner, the latter moves, consequently realizing the requested operation.
  • the kinematic chain 3 can be modified appropriately, for example by varying the number of its constructive components, their relative arrangement and/or their geometric configuration.
  • an actuator thus provided allows to significantly simplify the constructive architecture of the circuit breaker with respect to the current state of the art, by eliminating or at least significantly reducing the need of springs and/or of other complicated and cumbersome components; the fact should also be stressed that the use of a vacuum interruption technique does not require excessive switching forces, so that the combination of said interruption method with an electromagnetic actuation produces a synergistic effect which allows to further optimize the geometric and energy sizing of the circuit breaker as a whole, and to reduce testing and calibration operations as well.
  • an electromagnetic actuator without permanent magnets; in this case, however, the actuator must be provided with a system which is suitable to maintain the pivot 20 in stable equilibrium at the positions it reaches at the end of the switching operation, differently from what occurs when using permanent magnets, where this function occurs automatically and without using additional components.
  • FIG. 1 illustrates a single-pole circuit breaker; the above described solution can in any case be implemented easily and effectively in the case of a multiple-pole power circuit breaker.
  • each pole uses a vacuum enclosure 1 which contains at least one fixed contact 6 and at least one moving contact 7.
  • Each moving contact 6 is operatively connected to actuation means which supply the energy required to move said moving contacts and to determine coupling/uncoupling with respect to the corresponding fixed contacts.
  • a single electromagnetic actuator 2 is provided which is operatively connected to the corresponding movable contact.
  • the electronic command unit 9 it is possible to realize a strategy of switching operations in relation to the phases of the electrical network to which the circuit breaker is connected.
  • measuring means such as measuring transformers, which send information about the current and/or voltage trend of the network phases to the unit 9; in its turn, the unit 9, on the ground of the information received, drives the actuators 2 in order to perform synchronized operations for each phase, independently from the others.
  • a unique electromagnetic actuator 2 an operating shaft which is operatively connected to said electromagnetic actuator 2 and, for each pole, a kinematic chain 3 which is suitable to connect each moving contact to said operating shaft.
  • the opening/closure operations of the circuit breaker occurs simultaneously for all the poles, as described above and can be realized in a synchronized way for one phase, which is considered as a reference.
