Detailed Description
Embodiment 1.
Hereinafter, embodiment 1 will be described with reference to fig. 1 to 3. Fig. 1 is a general configuration diagram showing an electromagnetic operation device and a switching device operated by the electromagnetic operation device in embodiment 1. The electromagnetic operating device 100 includes an electromagnetic operating portion 4 connected to a movable side of the switch 1 in which the vacuum valve 2 is provided, and configured to switch the switch 1, and a driving power supply portion 12 configured to supply power to the electromagnetic operating portion 4. As will be described later, the electromagnetic operation unit 4 and the driving power supply unit 12 are connected by a connection circuit constituted by connecting the electromagnetic operation unit side connection circuit 161 and the driving power supply unit side connection circuit 162, and power is supplied from the driving power supply unit 12 to the electromagnetic operation unit 4 via the electromagnetic operation unit side connection circuit 161 and the driving power supply unit side connection circuit 162.
The electromagnetic operating section 4 has a fixed core 7 and a movable core 10, and an open-pole coil 8a and a closed-pole coil 8b are coaxially arranged with the movable core 10 so as to surround a part of the movable core 10. A permanent magnet 9 for pulling the movable iron core 10 in the pole closing direction is provided inside the fixed iron core 7, and an open spring 11 for biasing the movable iron core 10 in the pole opening direction is provided on the outer side in the axial direction of the fixed iron core. Further, one end of the movable shaft 6 is fixed to the movable iron core 10. The movable shaft 6 extends from the movable iron core 10 toward the switch 1, and the other end of the movable shaft 6 is connected to one end of the insulating rod 3 via the contact pressure spring 5. The insulating rod 3 extends from the contact pressure spring 5 into the vacuum valve 2, and the other end of the insulating rod 3 is provided with an electrode.
The movable iron core 10 is moved in the opening and closing directions by electromagnetic force from the excited opening and closing coils 8a and 8b. This causes the switching device 1 to perform the pole opening operation and the pole closing operation. The open-pole coil 8a and the closed-pole coil 8b are excited by power supply from the drive power supply unit 12. The driving power supply unit 12 includes: the direct current power supply 13 is a first power supply unit; two electromagnetic coil capacitors 15a and 15b for storing power from the dc power supply 13; and a first control unit serving as a control board 14 that operates by power from the dc power supply 13 and controls current flowing through the discharge of the solenoid capacitors 15a and 15b. The control board 14 controls the current supplied from the solenoid capacitors 15a and 15b to the open-pole coil 8a and the close-pole coil 8b, and controls the switching operation of the switching device 1, based on an open-pole command or a close-pole command input by a host control device (not shown) or a user.
The solenoid capacitor 15a corresponds to the open coil 8a, and the current from the solenoid capacitor 15a is supplied to the open coil 8a. Similarly, the solenoid capacitor 15b corresponds to the closed coil 8b, and the current from the solenoid capacitor 15b is supplied to the closed coil 8b. Therefore, the electromagnetic operation portion side connection circuit 161 and the driving power supply portion side connection circuit 162 have at least a circuit corresponding to the open coil 8a and a circuit corresponding to the close coil 8b.
The solenoid-operated-portion-side connection circuit 161 is connected to the open-pole coil 8a and the closed-pole coil 8b of the solenoid operated portion 4, and solenoid-operated-portion-side circuit connection means 16a1 and 16b1 are provided at the end portion of the solenoid-operated-portion-side connection circuit 161 opposite to the solenoid operated portion 4. The drive power supply unit side connection circuit 162 is connected to the control board 14 of the drive power supply unit 12, and drive power supply unit side circuit connection means 16a2 and 16b2 are provided at an end portion of the drive power supply unit side connection circuit 162 opposite to the drive power supply unit 12. The electromagnetic operation portion side circuit connection unit 16a1 and the driving power supply portion side circuit connection unit 16a2 correspond to the open coil 8a and the electromagnetic coil capacitor 15a, and the electromagnetic operation portion side circuit connection unit 16b1 and the driving power supply portion side circuit connection unit 16b2 correspond to the closed coil 8b and the electromagnetic coil capacitor 15b. The electromagnetic operation unit side connection circuit 161 and the driving power supply unit side connection circuit 162 are connected to each other by connecting the electromagnetic operation unit side circuit connection unit 16a1 and the driving power supply unit side circuit connection unit 16a2, and the electromagnetic operation unit side circuit connection unit 16b1 and the driving power supply unit side circuit connection unit 16b2, respectively, to constitute a connection circuit for connecting the electromagnetic operation unit 4 and the driving power supply unit 12.
In embodiment 1, the electromagnetic operation unit side circuit connection units 16a1 and 16b1 and the driving power source unit side circuit connection units 16a2 and 16b2 are in a detachable form, and are, for example, a plug and a socket connected to the plug. Thus, the electromagnetic operation portion side circuit connection units 16a1, 16b1 and the driving power source portion side circuit connection unit can be realized using a connector constituted by a plug and a socket.
As described above, in normal operation, the electromagnetic operating unit 4 and the driving power supply unit 12 are connected by the electromagnetic operating unit side connection circuit 161 and the driving power supply unit side connection circuit 162, and the driving power supply unit 12 supplies power to the opening coil 8a and the closing coil 8b and controls the switching of the switching device 1.
Next, an operation in an emergency will be described. Fig. 2 is a configuration diagram of the emergency operation device according to embodiment 1. Here, the "emergency" is a situation in which it is impossible to supply power from the driving power supply unit 12 to the electromagnetic operating unit 4, and examples thereof include a case in which the dc power supply 13 is lost, a case in which the control board 14 is out of order, a case in which the solenoid capacitors 15a and 15b are out of order, a case in which the driving power supply unit side circuit connection circuits 162 between the driving power supply unit side circuit connection units 16a2 and 16b2 and the driving power supply unit 12 are disconnected, a case in which a plurality of failures such as those described above are generated, and the like. The emergency operation device 121 includes: a second power supply unit as the power supply unit 20; two electromagnetic coil capacitors 19a and 19b for storing power from the power supply unit 20; and a second control unit serving as a control board 18 for controlling the current flowing by discharging the solenoid capacitors 19a and 19 b. In the emergency operation device 121, the power supply unit 20, the solenoid capacitors 19a and 19b, and the control board 18 are integrally formed, and the emergency operation device 121 is portable.
The emergency operation device side connection circuit 17 is connected to the control board 18. Emergency operation device side circuit connection means 17a, 17b connectable to the electromagnetic operation portion side circuit connection means 16a1, 16b1 are provided at an end portion on the opposite side of the control board 18 of the emergency operation device side connection circuit 17. The emergency operation device side circuit connection means 17a, 17b are, for example, plugs or sockets, have the same connector shape as the driving power source side circuit connection means 16a2, 16b2, and can be connected to the electromagnetic operation portion side circuit connection means 16a1, 16b1 in the same manner as the driving power source portion side circuit connection means 16a2, 16b2.
The power supply unit 20 includes a manual power generator 22 to which a rotation handle 23 is attached and which generates power by rotation of the rotation handle 23, and a control power supply capacitor 21 which stores power generated by the manual power generator 22. The control board 18 operates by using the power stored in the control power supply capacitor 21, and controls the current generated by the discharge of the solenoid capacitors 19a and 19 b.
Fig. 3 is a diagram showing an overall configuration of a state in which the electromagnetic operating unit and the emergency operating device are connected. In an emergency, first, the electromagnetic operation unit side circuit connection unit 16a1 and the driving power supply unit side circuit connection unit 16a2, and the electromagnetic operation unit side circuit connection unit 16b1 and the driving power supply unit side circuit connection unit 16b2, which are in the connected state, are respectively pulled apart, and the respective electrical connection states are released. Next, the solenoid-operated-unit-side circuit connection means 16a1, 16b1 are connected to the emergency-operated-device-side circuit connection means 17a, 17b, so that power supply from the emergency operation device 121 to the solenoid operated unit 4 is possible. The control board 18 controls the current supplied from the solenoid capacitors 19a and 19b to the open-pole coil 8a and the closed-pole coil 8b in response to an open-pole command or a close-pole command issued by a control device (not shown) in the upper side or by user input, and resumes the switching control of the switching device 1.
When the return to normal state is completed, the connection state between the electromagnetic operation unit side circuit connection unit 16a1 and the emergency operation device side circuit connection unit 17a, and the connection state between the electromagnetic operation unit side circuit connection unit 16b1 and the emergency operation device side circuit connection unit 17b are released. Subsequently, the electromagnetic operation unit side circuit connection means 16a1 and 16b1 are connected to the drive power source unit side circuit connection means 16a2 and 16b2, and the state is returned to the normal state.
The solenoid capacitor 19a corresponds to the open coil 8a, and the current from the solenoid capacitor 19a is supplied to the open coil 8a. Similarly, the solenoid capacitor 19b corresponds to the closed coil 8b, and the current from the solenoid capacitor 19b is supplied to the closed coil 8b. Therefore, the emergency operation device side connection circuit 17 has at least a circuit corresponding to the open coil 8a and a circuit corresponding to the closed coil 8b.
The emergency operation device 121 may be provided with a monitoring means for monitoring the electric storage conditions of the power supply capacitor 21 and the solenoid capacitors 19a and 19b, and giving a warning when it is determined that the power required for switching control of the switch 1 is not stored or the possibility of the power not being stored is high. By providing such a monitoring means, the user can timely perform power generation by the power supply unit 20, and can prevent the switching operation control from being stopped due to insufficient power.
According to embodiment 1, even when an abnormality occurs in the control board that controls the switching operation of the switch, the switching control can be restarted promptly. More specifically, in connection between an electromagnetic operation unit of a switch and a driving power supply unit for controlling power supply to the electromagnetic operation unit, a connection circuit for connecting the electromagnetic operation unit and the driving power supply unit is configured by connecting an electromagnetic operation unit side connection circuit and a driving power supply unit side connection circuit. The electromagnetic operation portion side connection circuit and the driving power source portion side connection circuit are connected by an electromagnetic operation portion side circuit connection unit and a driving power source portion side circuit connection unit provided at each end portion. When an abnormality such as a failure occurs in the control board of the drive power supply unit, the connection state between the electromagnetic operation unit side circuit connection means and the drive power supply unit side circuit connection means is released, and an emergency operation device provided with a control board for controlling the switching operation of the switch is connected to the electromagnetic operation unit side circuit connection means. Thus, the emergency operation device is connected to the electromagnetic operation unit, and thereafter, the switching operation of the switching device is controlled by the emergency operation device. The emergency operation device is provided with a manual generator, and an emergency power supply is not required to be prepared. In this way, the switching control can be restarted only by switching the connection destination of the electromagnetic operation portion side circuit connection means from the drive power source portion to the emergency operation device, so even when an abnormality occurs in the control board that controls the switching operation of the switch, the switching control can be restarted promptly.
The same effects are also obtained when confirming the state after installation, as an example other than the emergency. That is, when the control power supply is not turned on after the switch is mounted, the state confirmation after the mounting can be started promptly.
