Definitions

  • the present application relates to the field of an electromagnetic operation device which operates, for example, a switch.
  • a vacuum circuit breaker which has incorporated in a vacuum container thereof a movable contact and a fixed contact, wherein opening/closing operation is carried out by causing the movable contact to move.
  • An electromagnetic operation device which operates the switch is configured so as to enable not only electromagnetic operation but manual operation.
  • opening operation for example, an operator causes a rotation shaft to pivot, thereby driving a lever fixed to the rotation shaft, and the lever directly pushes a movable shaft of the electromagnetic operation device, thus driving the device.
  • the rotation shaft is configured to be driven using a tool, such as a wrench (for example, refer to Japanese Patent No. 5,901,351 ).
  • a configuration is disclosed such as to carry out opening/closing operation for three phases' worth of switch portions (switches) all at one time, wherein a handle as another part is mounted on a main shaft (a rotation shaft) when in manual operation, and a drive shaft (a movable shaft) is directly driven with a lever fixed to the main shaft (for example, refer to Japanese Patent No. 4,668,165 ).
  • the electromagnetic operation device of Japanese Patent No. 5,901,351 is such that a mechanism portion for manual operation is provided paired with the electromagnetic operation device. For this reason, when a configuration is assumed in which three phases' worth of switches are included in one switching apparatus and an electromagnetic operation device is provided for each of the three phases, it is necessary to carry out manual operation per phase when carrying out manual opening operation, so that an open phase state occurs temporarily.
  • a structure is such that the movable shaft is directly driven with the lever fixed to the rotation shaft, thus requiring operation torque high enough to directly rotationally operate the rotation shaft to which the lever is fixed, and there is a problem with operability in that the operation torque increases with an increase in the number of devices to be manually operated all at one time. Also, there is also a problem with operability in that a handle for manual operation, or the like, is not equipped on the device side.
  • a circuit breaker includes a circuit breaker housing and a plurality of independent poles.
  • Each of the independent poles includes separable contacts, a voltage sensor mounted on or within the circuit breaker housing and being structured to sense voltage operatively associated with the separable contacts, and an electro-magnetic actuator structured to open and close the separable contacts.
  • a point-on-wave controller is housed by the circuit breaker housing and cooperates with the sensors and the actuators of the independent poles to independently and synchronously open and close the separable contacts of the independent poles.
  • a solenoid controller includes: a plunger which is fixed to the outer portion of a shaft; an inputting coil which makes the plunger move in the input direction; a tripping coil which makes the plunger move in the direction for tripping; a tripping spring which has a repulsive force in the tripping direction to the plunger; an attraction iron core which is located in the input direction of the plunger and on the outer portion of the shaft; a yoke which covers the outer surface of the inputting and tripping coils; a permanent magnet which is located between the yoke and the attraction iron core to form a magnetic flux path passing through the plunger, the yoke, and the attraction ion core at the time of inputting operation completion; and an annular magnetic material which is located between the inputting and tripping coils at a position where a magnetic flux density generated at the start of excitation for the inputting coil becomes larger than a magnetic flux density generated in the plunger
  • an encapsulated medium voltage vacuum circuit interrupter includes a line terminal, a load terminal, a vacuum interrupter, an operating mechanism and an elongated, insulated, generally cylindrical encapsulating housing.
  • the vacuum interrupter includes a vacuum envelope containing a fixed contact assembly and a movable contact assembly movable between a closed circuit position in electrical communication with the fixed contact assembly and an open circuit position spaced apart from the fixed contact assembly.
  • the fixed contact assembly is electrically interconnected with the line terminal.
  • a flexible conductor electrically connects the movable contact assembly with the load terminal.
  • the operating mechanism moves the movable contact assembly between the closed circuit position and the open circuit position.
  • the housing includes a first end supporting the line terminal and an opposite second end supporting the load terminal. The housing encloses the vacuum interrupter, the flexible conductor and the operating mechanism.
  • Document US 2013/187733 A1 states an electrical switchgear which combines, connected electrically in series, a visible disconnect switch (operated by a main switch actuator) and a circuit breaker module (which may also be termed an interrupter) including circuit breaker contacts which are opened and closed by an electrically-activated magnetic actuator and capable of interrupting fault currents.
  • the magnetic actuator is stable in either a breaker-closed state or a breaker-open state without requiring electrical current flow through the magnetic actuator.
  • An interlock is provided such that, as the main switch actuator begins to move from its switch-closed position to its switch-open position, the breaker-closed state is destabilized to open the circuit breaker contacts.
  • An interlock is also provided such that the circuit breaker contacts cannot close while the visible disconnect switch is open.
  • the present application has been made to solve the problem, and an object of the present application is to provide an electromagnetic operation device which enables manual operation to be carried out for a plurality of switches all at one time and also which is superior in operability.
  • a configuration is such that the cam mounted on the shaft is interlocked with the link member, causing the movable shaft to move, so that design margin is higher by the amount equivalent to a larger number of parts interlocking with the shaft than in the case of a configuration in which one member for causing the movable shaft to move is directly mounted on the shaft, and it is easy to adjust the operation torque necessary for manual operation, so that it is possible to operate a plurality of movable shafts all at one time by manually operating the handle portion fixed to the shaft, and thus possible to improve operability.

Accordingly, it is easy to carry out the manual opening operation for the three phases' worth of switches 200 all at one time without depending only on the operator's operational force of operating the handle portion 7.
  • the contact pressure of the plunger 40 is highest in the intermediate position of the pivoting range of the shaft 5, so that it is possible to inhibit the movable shaft 1 which has once come into the open state from returning to the closed state and stably hold the open state.
  • the contact pressure of the plunger 40 increases gradually as opening operation proceeds, so that when opening operation starts, a force acts such as to restore the handle portion 7 to its previous closed state. Therefore, even though a load is mistakenly put on the handle portion 7, the plunger 40 acts so as to hold the closed state, and it is possible to prevent malfunction.
