High voltage disconnecting switch control
A system for controlling a high voltage switch having at least one connect/disconnect arm, the system comprising: actuating means for displacing the at least one connect/disconnect arm; an optical position sensor for determining a position of the at least one connect/disconnect arm; and a control module operatively connected to the actuating means and adapted to dynamically adjust a speed of motion of the at least one connect/disconnect arm as a function of the position of the at least one connect/disconnect arm.
1. A system for controlling a high voltage switch having at least one connect/disconnect arm, the system comprising:
actuating means for displacing said at least one connect/disconnect arm;
an optical position sensor for determining a position of said at least one connect/disconnect arm; and
a control module operatively connected to the actuating means and adapted to dynamically adjust a speed of motion of said at least one connect/disconnect arm as a function of said position of said at least one connect/disconnect arm.
2. A system as claimed in claim 1 , wherein said control module comprises at least three speeds to which said at least one connect/disconnect arm can be set.
3. A system as claimed in claim 1 , wherein said control module comprises digital logic.
4. A system as claimed in claim 1 , further comprising at least one additional sensor connected to said control module for sensing at least one operating parameter of said system.
5. A system as claimed in claim 4 , wherein said at least one additional sensor is a sensor for sensing environmental conditions of said system.
6. A system as claimed in claim 5 , wherein said control module is adapted to determine a temperature and humidity level of said system in order to react to climate changes therein.
7. A system as claimed in claim 1 , further comprising at least one external communication port.
8. A system as claimed in claim 7 , wherein data obtained by said system can be retrieved via said at least one external port.
9. A system as claimed in claim 1 , further comprising external indicators showing a status of said system.
10. A system as claimed in claim 9 , wherein said external indicators show a position of said connecting/disconnecting arm.
11. A system as claimed in claim 1 , wherein said actuating means comprise a motor having at least one speed of operation for opening and for closing said at least one connect/disconnect arm.
12. A system as claimed in claim 1 , wherein when opening said at least one connect/disconnect arm, said control module adjusts said at least one connect/disconnect arm to a first speed until it reaches a point where an arc would commence, a second speed greater than said first speed until said arc is cut, and a third speed less than said second speed until a fully opened position is reached and a brake is activated, thereby bringing said at least one connect/disconnect arm to a stop.
13. A system as claimed in claim 1 , wherein when closing said at least one connect/disconnect arm, said control module adjusts said at least one connect/disconnect arm to a first speed until after a formed arc has been cut and a second speed until a fully closed position is reached and a brake is activated, thereby bringing said at least one connect/disconnect arm to a stop.
14. A system as claimed in claim 1 , wherein said control module is configured to adjust the speed of motion of said at least one connect/disconnect arm as a function of a type of equipment of said arm, and provides different speeds for initial movement of the arm, after an arc has been cut, and slow down of the arm.
15. A method for controlling a high voltage switch having at least one connect/disconnect arm, the method comprising:
optically sensing a position of said connect/disconnect arm;
dynamically adjusting a speed of motion of said at least one connect/disconnect arm as a function of said position of said at least one connect/disconnect arm; and
actuating said at least one connect/disconnect arm in accordance with said speed of motion.
16. A method as claimed in claim 15 , wherein said dynamically adjusting a speed of motion comprises adjusting said at least one connect/disconnect arm to at least three speeds.
17. A method as claimed in claim 15 , further comprising sensing at least one additional operating parameter of said system.
18. A method as claimed in claim 17 , wherein said at least one additional parameter is an environmental condition of said system.
19. A method as claimed in claim 18 , further comprising determining a temperature and humidity level of said system in order to react to climate changes therein.
20. A method as claimed in claim 15 , further comprising providing at least one external communication port on said system.
21. A method as claimed in claim 20 , further comprising retrieving data obtained by said system via said at least one external port.
22. A method as claimed in claim 15 , further comprising providing external indicators showing a status of said system.
23. A method as claimed in claim 22 , wherein said external indicators show a position of said connecting/disconnecting arm.
24. A method as claimed in claim 15 , wherein said actuating said at least one connect/disconnect arm comprises operating said at least one connect/disconnect arm at a first speed until it reaches a point where an arc would commence, a second speed greater than said first speed until said arc is cut, and a third speed less than said second speed until a fully opened position is reached and a brake is activated, thereby bringing said at least one connect/disconnect arm to a stop.
25. A method as claimed in claim 15 , wherein said actuating said at least one connect/disconnect arm comprises operating said at least one connect/disconnect arm at a first speed until after a formed arc has been cut and a second speed until a fully closed position is reached and a brake is activated, thereby bringing said at least one connect/disconnect arm to a stop.
26. A method as claimed in claim 15 , wherein said actuating said at least one connect/disconnect arm comprises adjusting the speed of motion of said at least one connect/disconnect arm as a function of a type of equipment of said arm, and providing different speeds for initial movement of the arm, after an arc has been cut, and slow down of the arm.
