Definitions

  • the present invention generally relates to an electrical switch used for opening and closing an electrically conductive path between an electrical supply and an electrical load.
  • the present invention relates to a regulated power supply assembly suitable for operating such an electrical switch.
  • At least one movable contact is displaced relative to at least one pair of stationary contacts to establish or interrupt an electrically-conductive path between supply-side and load-side stationary contacts.
  • the supply-side and load side stationary contacts are connected to an electrical supply and an electrical load respectively.
  • An electromagnetic assembly is included to provide a driving force such as to cause a desired displacement of the movable contact from an open position to a closed position during a switching-on operation.
  • a biasing mechanism is included to provide a biasing force to return the movable contact from the closed position to the open position during a switching-off operation.
  • a typical electromagnetic assembly includes a magnet frame, which includes a stationary portion referred to as 'yoke' and a movable portion referred to as 'armature' (sometimes also referred to as 'anker').
  • the yoke and the armature have a complementary construction with air gaps in between confronting ends.
  • the armature of the electromagnetic assembly is coupled to the movable contacts, and is held in a spaced relationship from the yoke using the biasing mechanism.
  • the yoke is associated with an electromagnetic coil.
  • the electromagnetic coil is energized through a power supply assembly to establish a magnetic flux through the yoke and consequently, through the armature such that the armature moves under the influence of magnetic force against the biasing force exerted by the biasing mechanism, thereby providing a driving force to displace the movable contact from the open position to the closed position thereof.
  • the power supply assembly de-energizes the electromagnetic coil such that the movable contact returns to the open position under influence of the biasing force exerted by the biasing mechanism.
  • electrical switches are required to handle high electrical loads, with electrical currents ranging from hundreds to even thousands of amperes at correspondingly high electrical voltages.
  • one approach adopted to mitigate the problem of arcing and resulting damage to the electrical switch while interrupting an electrical current there through during the switching-off operation is to ensure that movable contacts are separated from corresponding stationary contacts as quickly as possible.
  • the control circuit includes first and second input terminals to receive a control signal for operating the electrical switching device.
  • a first transistor has a conduction path connected in series with the electromagnetic coil between the first and second control terminals.
  • a controller applies a series of electrical pulses to a control terminal of the first transistor to switch that transistor into a conductive state and apply current pulses to the coil.
  • a fly-back circuit has a first diode and a second transistor connected in series to provide a conductive path in parallel with the electromagnetic coil for current produced in the electromagnetic coil when the first transistor is nonconductive.
  • the second transistor is biased into a first conductive state by the control signal.
  • the second transistor Upon removal of the control signal from the first and second input terminals, the second transistor is biased into a second conductive state by current produced in the electromagnetic coil with the second conductive state being less conductive than the first conductive state.
  • the first conductive state acts to maintain an electromagnetic field produced by the coil between occurrences of the electrical pulses.
  • the second conductive state produces a voltage drop in the path for current produced in the electromagnetic coil when it is desired to deactivate the switching device. This action dissipates significant power to rapidly deplete the coil stored magnetic field which results in rapid opening of the switch contacts.
  • the electrical switch transitions from the closed position to the open position under the influence of the biasing force exerted by the biasing mechanism.
  • energy imparted to various movable components mainly the armature and the movable contact
  • Such mechanical stress adversely impacts operational life of the electrical switch.
  • uncontrolled opening may disadvantageously cause the movable contacts to rebound towards the corresponding stationary contacts, which may undesirably lead to formation of arc between the movable and the stationary contacts.
  • an electrical switch adapted for regulating transition from a closed position to an open position thereof. It is desirable that the electrical switch is adapted to not only ensure rapid separation between corresponding movable and stationary contacts such as to minimize arcing there between while transitioning from the closed position to the open position but energy imparted to various movable components, such as one or more movable contacts, an armature, and so on, within the electrical switch is also regulated to eliminate any mechanical damage thereto.
